F-Series System Meets Machine Safety StandardsMechan Controls has announced that the F-series electronic safety system has achieved the highest possible rating under EN ISO 13849-1, the international standard for machine safety. The F-series is a modular, multi-gate safety system that features a flexible control unit capable of monitoring up to 30 tamper-proof safety switches simultaneously.
In tests recently conducted by TUV Nord in Germany, the system achieved a Category Four rating, with Safety Integrity Level Three and Performance Level E. The F-Series main control module has dual safety outputs and monitoring for external circuits, while each connected safety switch has both LED and volt-free contact indication at the control unit.
For larger plants or where a complete production line is being monitored, the modular system can be expanded using Mechan's FX1 and FX2 extender units, which work alongside the FM1 master control module. The safety switches are robust, fully encapsulated and available in three sizes with the standard tamper-proof coding, while the CMA version gives the option of half a million unique codes.
The switches have a 10mm operating distance, which makes them easy to install and free from nuisance tripping, and they are well suited for use in harsh conditions and environments where frequent cleaning is essential. As a result, the F-series provides safe and reliable protection on machine guards of all kinds. It is used in industries such as food processing, dairies, pharmaceutical plants and the manufacture of concrete blocks and other construction materials.

Adept Offers Jai's 040 Progressive Scan CamerasTwo new Mini Camera Link (MCL) 0.4-megapixel progressive scan cameras from Jai are now available from Adept Electronic Solutions. The CM-040MCL (monochrome) and CB-040MCL (Bayer colour) cameras are targeted at clients requiring small, high-quality devices with advanced functionality at a cost-effective price. Jai has designed these MCL models for applications that require higher-bandwidth, real-time signalling and a lower latency than is possible using GigE interfaces.
At 776 x 582 pixels, the 040 models provide slightly greater resolution than basic VGA versions while maintaining a high frame rate of 60fps. The cameras utilise the Sony ICX415 charge-coupled device and, while at full resolution output is at 61fps, higher frame rates can be achieved by using the partial-scan or vertical-binning modes.
The CM-040MCL and the CB-040MCL feature auto-iris lens video output to support the dynamic lighting conditions usually found in outdoor applications such as intelligent traffic systems and surveillance. Both models are available with an optional factory-installed right-angle adapter, which enables the camera to 'look' at a 90 angle. Both are designed for a range of inspection tasks where physical access is limited.
The cameras provide practical, versatile solutions in a range of deployments, including in the automotive industry, such as for inspection, high-precision gauging and process monitoring; pharmaceuticals, such as for the inspection of blister packages and for fill level control; in the beverage industry, such as for the control of the fill levels of defective bottles; in the food industry, such as for sorting; and for electronics inspection.

Voltammetric Device Measures Labile Copper ContentThe Metrohm 797 VA Computrace can be used for the determination of labile copper in sea water. Spectroscopic methods can only determine the total concentrations of metals, but with voltammetry it is possible to differentiate between the different oxidation states of copper. This allows statements to be made about the biological availability and toxicity, making voltammetry an essential tool in environmental analysis.
Copper is one of the most toxic-heavy metals known to marine life, generally concentrations of heavy metals are comparatively low in open sea areas where human activities have not yet had a major detrimental effect. However, in coastal area, contamination is usually more widespread often in offshore sediments close to municipal and industrial discharge points. Many marine and research institutions are interested in determining the relationship between the labile (or free copper) and total copper, both of which can easily and reliably be performed using the 797 VA Computrace from Metrohm.
The 797 VA Computrace is a modern voltammetric measuring instrument that connects to a PC via a USB connection. The Windows XP-based PC software controls the measurement, records the measuring data and allows full evaluation of the recorded information. The sample and auxiliary solutions are added to the reaction vessel and the labile copper is determined on a mercury film formed at the surface of the ultra-trace electrode. By performing the analysis first using an ultra-trace electrode then separately using a classic mercury electrode, it is possible to measure first the values of labile and then total copper to determine the ratio of the different species.
Whether the labile or total copper is being determined, the process can be partially or fully automated through the use of Metrohm Dosino dispensing devices and autosamplers. The low running costs are an additional bonus point for voltammetry requiring no expensive combustible gases or reconstruction of the laboratory infra-structure to accommodate specialist ducting and fume hoods. Apart from the small amounts of reagents required for the analysis, only small volumes of pure nitrogen are required.
GEA Presents Spray And Fluid Bed Drying TechnologyGEA Niro will be exhibiting technologies in the field of spray and fluid bed drying for the pharmaceutical, food and beverage, and chemical industries at Powtech 2010. The company will be displaying one of its smallest spray dryers, the SDMicro, on its stand. The lab-scale spray dryer is equipped with a two-fluid nozzle for atomisation and can be applied for both water and organic solvent-based formulations. The SDMicro is designed with the smallest possible spray drying chamber that allows for retaining the same air flow pattern as a large-scale spray dryer.
This makes it possible to conduct realistic tests at a very small scale and produce small quantities of powder for product and concept evaluations. The company will also exhibit its Drynetics method, which allows drying parameters to be established based on the study of one droplet of a given substance. The technique allows real-world measurements (for example, drying time and stickiness of a given feed) to be incorporated into CFD simulations. This makes it possible to establish the spray dryer performance by precisely analysing the results of one-droplet experiment.
The Drynetics analysis is used to investigate product formulations and to optimise spray drying plant designs - for new or existing plants. The company will also display a set of 3D animations showing a GEA Niro spray dryer with heat recuperation, a Contact Fluidizer fluid bed dryer and a Swirl Fluidizer dryer in operation. The 3D animations are an opportunity to see what takes place inside the dryers and to learn what happens during the drying process.
The company's process technologists and sales managers will be available to discuss how GEA Niro's range of drying systems can be applied for production of a wide range of chemical, food and pharmaceutical products. GEA Niro specialists are also available to discuss plant upgrades and rebuilds. The GEA Niro stand will be located in hall 1, 1-115, at the Powtech event, from 27-29 April 2010.
Sandvik Focuses On Granulation Systems At PowtechSandvik Process Systems has announced that it will exhibit products this year's Powtech fair. With granulation systems available for applications such as foodstuffs, subcooling melts, thixotropy, abrasive and corrosive products, Sandvik offers a wide ranges of process solutions. Working examples of two steel belt-based granulation systems - the Rotoform 3000 and Rotoform HS (high-speed) models - will provide the focus of the company's stand, booth 425 in hall 7.
The steel belt cooler is designed as an integrated system, incorporating everything needed to complete the solidification process, from Rotoform feeding, steel belt and automatic belt tracking, to release agent, discharge device and exhaust air system. Each of the nine different members of the Rotoform range has been designed to meet specific process requirements and all are based around the same basic concept. At the heart of every system is a special drop depositor, the Rotoform, which feeds droplets of the molten product onto a continuously running steel belt.
This is cooled by water from the underside, rapidly solidifying the product. The droplets are discharged in the form of dry, uniform, free flowing and dust-free pastilles - suitable for transport, storage and subsequent processing. It is a flexible process capable of handling molten products at temperatures of up to 320C and viscosities up to 50.000 cP. Depending on the system used, pastilles can be produced in diameters from 1mm up to 30mm, and the diameter can be adjusted on the machine or, in the case of more major change, by switching components.
The system is also environmental friendly. The fact that there is no contact between cooling water and the product being processed means no risk of cross contamination; while fast cooling times mean little or no exchange of gases, vapour or oxygen between chemical product and the surrounding atmosphere. The Rotoform 3000 is the standard unit and is widely used for products such as hot-melt adhesives, resins, sulphur and waxes. However, some oil and gas refineries need higher capacity solutions and it was to meet this need that the HS model was developed.
Through the use of a bigger rotating shell, reducing the centrifugal force on the droplet shape - Sandvik said it has been able to produce a system that delivers up to two times the throughput of a standard Rotoform, while maintaining control of end-product quality and delivering a consistent pastille with a regular, hemispherical shape. Sandvik can also supply conveying, storage and loading facilities, together with associated control systems. The company has invested in a network of test centres where all nine Rotoform types are available for demonstration and tests on customer products. Transportable units have also been developed to allow tests and pilot production to be carried out at customer sites.

Bruel And Kjaer Helps To Test Lift Sound QualityOrona has used Bruel and Kjaer's Head and Torso Simulator (HATS), binaural microphones and Pulse sound-quality software to analyse the sound-quality behaviour of its lifts. This equipment allowed it to correlate the sound quality with the different noise sources and to study the most appropriate ways to improve lift comfort. Orona (manufacturer of lifts), Mondragon Goi Eskola Politeknikoa (MGEP [Engineering Faculty of Mondragon University]) and Ikerlan (Research Centre) formed a consortium to investigate the sound quality in Orona's lifts.
According to Unai Galfarsoro, the coordinator of the acoustic and vibration group at Mondragon University: 'The reason for establishing the sound-quality project is the need to go beyond the traditional A-weighted sound pressure level, which is usually used to rank different noise sources, because we believe that a complete sound-quality analysis gives wider and more reliable results.
'The objective is to analyse the actual sound-quality performance of the various types of Orona lifts, to correlate the sound quality with the different noise sources and to study the most suitable approaches to improve the comfort of the lifts,' he added. Before carrying out the sound-quality process, the types of lifts to be analysed were selected and six of each type were tested. Three up and three down full travelling cycles (doors closing, acceleration, constant speed, deceleration and doors opening) were measured from the bottom to the top floor and back and the time data was the basis for the following sound-quality analysis.
The equipment used consisted of Bruel and Kjaer's Sound Quality Head and Torso Simulator (HATS) Type 4100-D, equipped with two microphones for binaural noise measurements. The two signals were recorded using a Pulse IDAe front-end and time data recorder software. 'The Pulse front-end is useful for measurements inside a moving lift as it makes no noise at all (its fan can be switched off during measurements) and it can be battery operated. 'Besides, time data recorder software is extremely simple to configure and use for time data measurements,' added Galfarsoro.
Imaging Tool Expands Research OpportunitiesThe installation of a Jeol Electron Probe Microanalyzer (EPMA) aims to expand research and educational opportunities for students, faculty and industry in southeastern North Carolina. In January, Jeol completed the installation of its latest EPMA, also known as a microprobe, at the Southeastern North Carolina Regional Microanalytical and Imaging Center (SENCR-MIC).
The state-of-the-art facility opened in 2009 as a joint collaboration between Fayetteville State University (FSU) and the University of North Carolina (UNC) at Pembroke. The microprobe enables detailed surface analysis that reveals a lot of information about both hard and soft samples. FSU and UNC students will have access to this electron microscope to advance environmental, geological and forensic science research.
'We'll be able to use it to compare paint chips, analyse soil samples, gunshot residue and micro tool marks,' said Dr Steven Singletary, director of the SENCR-MIC. Singletary sees this resource as benefiting both future careers and the future of the region in southeastern North Carolina. Research at this level is an opportunity for students who typically hold down jobs while attending school and have responsibilities that would prevent them from obtaining this type of training away from home.
Singletary and his fellow faculty members are hopeful that access to this instrumentation will produce a more highly trained workforce, which will in turn attract more businesses to the area. The SENCR-MIC will be a resource for both Fayetteville State University and the University of North Carolina at Pembroke. Additionally, local industry and government will have access to the facility for research.
Cold-PCR Technology Detects Tumour Mutations
Transgenomic has validated the use of its licensed Cold-PCR technology to detect colorectal tumour-associated KRAS mutations that determine efficacy of recently developed therapies. These mutations were detected in plasma samples in which the mutation levels were too low for detection by standard DNA analysis methodologies such as Sanger sequencing. The study, which was performed by Transgenomic's Pharmacogenomics Services Laboratory in Omaha and the company's molecular biology research team in Gaithersburg, consisted of testing DNA extracted from colorectal tumour-matched plasma samples.
Screening with standard Sanger sequencing of the plasma samples resulted in only 70 per cent concordance between matched plasma and tumour due to missing KRAS codon 12 and 13 mutations. The samples were enriched by Transgenomic's Cold-PCR mutation enrichment technology before analysis with the Surveyor Scan KRAS assay. Cold-PCR preferentially amplifies genomic DNA mutations in comparison to normal, wild-type sequences. This enrichment and screening method can detect matched-tumour KRAS mutations in serum mutation levels at less than 0.1 per cent of total wild-type DNA.
This resulted in the accurate detection of all KRAS codon 12 and KRAS codon 13 mutations with full discrimination against wild-type or normal samples tested concurrently. Due to the extent of the enrichment process, all of these KRAS-containing plasma samples could subsequently be verified by DNA sequencing. It was confirmed by the study's pharmaceutical partner that there was a 100 per cent concordance between Transgenomic's mutation results and the matched-tumour KRAS genotypes.
'We believe that the developments in Cold-PCR that we are pursuing at Transgenomic will open the way for detecting tumour mutations in surrogate tissues and body fluids such as serum, plasma and urine rather than by tumour biopsy,' said Craig Tuttle, chief executive of Transgenomic. 'We intend to participate in further studies such as this with the aim of developing Cold-PCR serum assays for key gene mutations that are biomarkers for early tumour detection, tumour therapy efficacy, emergence of drug resistance biomarkers and relapse,' he added.
Cold-PCR was discovered in the laboratory of Dr Mike Makrigiorgos at the Dana Farber Cancer Institute. It has been exclusively licensed by Transgenomic for all Sanger Sequencing and mitochondrial DNA applications.
It can be coupled with Transgenomic's DNA mutation detection technologies to improve its sensitivity. When mutant and reference DNA samples from the same gene are mixed and re-annealed, variations between these sequences cause double-stranded DNA heteroduplexes to form. The Wave system employs denaturing HPLC to separate these homo- and hetero-duplexes by ion-pairing reverse-phase HPLC.
This technology has been in widespread use for genomic analysis being cited in more than 2,000 peer-reviewed publications. As an alternative offering, Transgenomic's Surveyor Nuclease cleaves such heteroduplexes with high specificity at sites of base mismatch or small insertions/deletions. It is a robust and reliable tool for analysing DNA variations, especially where the mutant alleles are at a very low concentration within the sample (less than one per cent of the total wild type allele concentration).
Cold-PCR protocols preferentially amplify heteroduplexes such that mutant alleles become enriched compared to normal alleles. The range of enrichment demonstrated to date varies from three to 100-fold, which will contribute to Transgenomic's target of achieving a 1/10,000 mutant to normal allele ratio detection in a routine, cost-effective and high throughput protocol. This level of detection will allow straightforward tumour analysis via surrogate tissues such as blood and urine.
Transgenomic has validated the use of its licensed Cold-PCR technology to detect colorectal tumour-associated KRAS mutations that determine efficacy of recently developed therapies. These mutations were detected in plasma samples in which the mutation levels were too low for detection by standard DNA analysis methodologies such as Sanger sequencing. The study, which was performed by Transgenomic's Pharmacogenomics Services Laboratory in Omaha and the company's molecular biology research team in Gaithersburg, consisted of testing DNA extracted from colorectal tumour-matched plasma samples.
Screening with standard Sanger sequencing of the plasma samples resulted in only 70 per cent concordance between matched plasma and tumour due to missing KRAS codon 12 and 13 mutations. The samples were enriched by Transgenomic's Cold-PCR mutation enrichment technology before analysis with the Surveyor Scan KRAS assay. Cold-PCR preferentially amplifies genomic DNA mutations in comparison to normal, wild-type sequences. This enrichment and screening method can detect matched-tumour KRAS mutations in serum mutation levels at less than 0.1 per cent of total wild-type DNA.
This resulted in the accurate detection of all KRAS codon 12 and KRAS codon 13 mutations with full discrimination against wild-type or normal samples tested concurrently. Due to the extent of the enrichment process, all of these KRAS-containing plasma samples could subsequently be verified by DNA sequencing. It was confirmed by the study's pharmaceutical partner that there was a 100 per cent concordance between Transgenomic's mutation results and the matched-tumour KRAS genotypes.
'We believe that the developments in Cold-PCR that we are pursuing at Transgenomic will open the way for detecting tumour mutations in surrogate tissues and body fluids such as serum, plasma and urine rather than by tumour biopsy,' said Craig Tuttle, chief executive of Transgenomic. 'We intend to participate in further studies such as this with the aim of developing Cold-PCR serum assays for key gene mutations that are biomarkers for early tumour detection, tumour therapy efficacy, emergence of drug resistance biomarkers and relapse,' he added.
Cold-PCR was discovered in the laboratory of Dr Mike Makrigiorgos at the Dana Farber Cancer Institute. It has been exclusively licensed by Transgenomic for all Sanger Sequencing and mitochondrial DNA applications.
It can be coupled with Transgenomic's DNA mutation detection technologies to improve its sensitivity. When mutant and reference DNA samples from the same gene are mixed and re-annealed, variations between these sequences cause double-stranded DNA heteroduplexes to form. The Wave system employs denaturing HPLC to separate these homo- and hetero-duplexes by ion-pairing reverse-phase HPLC.

Qiagen Acquires Exclusive Licence Of key PI3K GeneQiagen has announced that its DXS subsidiary has acquired the global and exclusive licence for biomarker PI3K from Johns Hopkins University to develop real-time-PCR and endpoint PCR assays. Research has shown that variation in the PI3K gene could be a key biomarker for use as a companion diagnostic with certain cancer treatments. The studies suggest that mutations in the PI3K oncogene are predictive for the success of certain treatments of patients suffering from lung, breast, colorectal and other cancers.
Qiagen has an active PI3K assay development and partnering programme with pharmaceutical companies to develop and market tests for new cancer drug candidates. Qiagen already markets a PI3K test for research use. This test is based on real-time polymerase chain reaction (RT-PCR), a widely available technology to make DNA sequences visible through amplification. The assay, which uses technology that allows a very significant sensitivity, detects mutations frequently missed by sequencing methods.
Johns Hopkins researchers assessed the biomarker during their evaluation of tyrosine kinase inhibitors targeting the EGFR (Epidermal Growth Factor Receptor) pathway. Various EGFR inhibiting drugs have shown to be not effective in cancer patients with mutations in genes of the EGFR pathway (EGFR, K-RAS, B-RAF and so on). Qiagen already markets several tests determining the mutation status in oncogenes. This portfolio includes tests for mutations of K-RAS and B-RAF, which are indicative for metastatic colorectal, lung and other cancers. The K-RAS test is CE-marked for companion diagnostic use with EGFR inhibitors Vectibix and Erbitux and is expected to be submitted for FDA approval shortly.

KTR Develops Coupling For Measurement And ControlKTR's Countex Coupling is a three-part, backlash-free, torsionally stiff coupling used mainly in measuring and control technology, such as encoders and tachometers. The compact design of the coupling is characterised by its simple assembly, reliable performance and suitability for use in confined spaces. The double cardanic design allows the coupling to compensate for all potential misalignments with minimal restoring forces.
The axial 'plug-in' of the coupling ensures an easy blind assembly. The coupling has aluminium crown-shaped hubs on the outside diameter, with a toothed cage made from temperature-resistant nylon. Set screws secure the hubs against axial movement. Countex can be used in temperatures of up to 160C. The first Countex Coupling available was a size 14 with rated torques of 1Nm and maximum bore diameter of 14mm.
KTR has now extended the range to include the smaller size 6 Countex Coupling with a rated torque of 0.3Nm and maximum bore diameter of 6mm. The coupling is available from stock at KTR with a range of bore sizes.
Westermo Enhances Wolverine Line-Extruder RangeWestermo Data Communications has expanded and improved its Wolverine range of industrial Ethernet line extenders with the addition of the DDW-225 and an enhanced version of the existing DDW-120. These rugged industrial products form part of Westermo's range of Ethernet SHDSL extenders that are used to establish reliable long-distance, high-speed remote connections between simple and complex Ethernet networks using any existing twisted pair copper cables. The DDW-225 line extender includes the WeOS system, which is already employed in Westermo's Redfox industrial routing switches.
WeOS is said to provide advanced switching and routing functionality that enable the management of complex industrial networks. The enhanced DDW-120 is aimed at simple point-to-point applications, or as a start or termination unit, together with any of the DDW-220/221/222/225 products, in daisy-chain applications. The latest version of the extender enables data transmission rates as high as 15.3Mbit/s in both directions, and transmission distances of over 10km, depending on cable quality. This increased data transmission rate will help the ever-increasing demands for bandwidth from applications such as transmitting high-definition video from remote sites.
The DDW-225 supports two SHDSL interfaces and has a built-in four-port managed Ethernet switch, enabling users to build complete Ethernet networks with daisy chains and ring topologies. Suitable for use in harsh industrial environments, the device offers a data transfer rate of 5.7Mbit/s in both directions, and transmission distances of up to 15km. This makes it useful for applications such as railway trackside, tunnels, highways, harbours, power stations and extended industrial plants. The DDW-225 also includes Westermo's FRNT (fast recovery of network topology) technology - claimed to be the fastest protocol on the market to reconfigure a network in the event of any failure of a link or hardware, which provides support for redundant rings.
The DDW-225 can also support multiple rings, with a FRNT ring running from the SHDSL interface and a RSTP ring from the switch port. Device functionality, including VLAN, Static Routing, Layer 3 switching, IGMP Snooping Firewall, SNMP V3 and VPN support, all help improve bandwidth support and network security. The DDW-120 is designed to be transparent for multicast addressing, is suitable for VLAN networks, allows VPN (Virtual Private Network) pass-through for IPSec (Internet Protocol Security) and can be used with protocols like Modbus/TCP and Profinet I/O. The DDW-120 is said to be simple to install, with no software configuration required.
When long or poor cabling is used, the settings can be adjusted via DIP-switches for optimised performance. The unit is also supplied with an advanced diagnostic utility that allows the installer to analyse the quality of the line and the connection status. As with other products in the Wolverine series, both models are suitable for tough industrial environments. The rugged units can operate in a wide temperature range and total galvanic isolation and transient protection are standard for all interfaces. The line interface is also equipped with extensive protection against over-voltages and transients.
HSTA And HSTAR Sensors Resist Heat And VibrationMacro Sensors' HSTA and HSTAR LVDT-based linear-position sensors offer the environmental resistance and short-stroke sensor body length for cylinder applications where these are critical. While linear-position sensors were once considered too long for hydraulic applications, the development of new winding techniques, such as computerised layer winding and improved microprocessing, has considerably reduced the length of the linear-position sensor body compared with its measurable stroke length. In fact, for short-stroke actuators and cylinders (less than 6in), Macro Sensors' linear-position sensors can be much shorter than a magnetostrictive sensor.
These linear-position sensors are hermetically sealed and AC-operated. They measure 3/4in (19mm) diameter and can survive in temperatures up to 200C and withstand high levels of shock and vibration. Coil windings are sealed against hostile environments to IEC standard IP-68. They are offered with either an axial (HSTA) or radial (HSTAR) connector - units can have a through bore for the fluid to pass or can seal the fluid in the RAM. The radial connector makes the installed length of the HSTAR LVDTs at least 2in shorter than comparable units, with an axially mounted connector for easier installation in tight spaces.
Accessible from both ends, the linear-position sensors can be easily cleaned of grit, dirt, dust or other contaminants for greater reliability and longer life. Available in ranges of +/-0.050in (+/-1.25mm) to +/-10.0in (+/-250mm), the HSTA and HSTAR sensors feature the high resolution, excellent repeatability and low hysteresis associated with LVDT (linear variable differential transformer) technology, as well as the highest sensitivity consistent with good linearity. The maximum linearity error for any of these sensors is +/-0.25 per cent of full-range output using a statistically best-fit straight line derived by the least squares method.
Macro Sensors offers custom designs for higher temperatures and pressure resistance, smaller diameters and connector options. HSTA and HSTAR Series LVDTs operate properly with any conventional differential input LVDT signal conditioner. Ranges of 1in or greater will also work with ratiometric LVDT signal conditioning. Macro Sensors offers a full line of LVDT signal conditioners that deliver optimum performance from any HSTA and HSTAR linear-position sensor.

Festo Actuators Offer +/-10 Micron Repeatability
Festo has brought out an extensive range of ultra-compact precision electric actuators that can be ordered from its online shop. This means that machine designers and builders can now take delivery of positioning actuators offering +/-10 micron repeatability within 24 hours of placing their order. Downloadable PC-based software for dimensioning electromechanical linear axes and electric motors, backed by native CAD models of the actuators, helps users accelerate design-in and machine build. Festo's new EGSK and EGSP series actuators provide exceptionally accurate positioning capabilities.
Featuring a one-piece solid-steel housing that also serves as a guide rail - conveying a high degree of rigidity to the design - they are ideal for applications demanding short and precise moves, especially where space is limited. Their low profile makes them particularly suitable for the type of small pick-and-place systems and X-Y tables used in the semiconductor manufacturing and pharmaceutical industries. The EGSK and EGSP electric actuators offer a choice of three classes of precision, with repetition accuracies of +/-3, +/-5 or +/-10 microns.
They are available in two performance categories, to help maximise applications flexibility. The EGSK range of standard-performance electric actuators comprises five models, with profile heights from 15 - 46mm. All five models employ a ball-screw drive, with a choice of pitches, and offer a wide variety of stroke lengths - from 25 to 800mm, depending upon the particular model. The +/-10 micron precision class versions of all EGSK actuators, which are suitable for the majority of applications and are therefore likely to prove the most popular, are available off-the-shelf from Festo.
The EGSP range of high-performance electric actuators use caged re-circulating ball bearings between the carriage and the guide, to further reduce friction and noise. There are four models in the range - with profile heights of 20, 26, 33 and 46mm - and again, each model is available with a choice of ball-screw drive pitches and a variety of stroke lengths, ranging from 25 to 800mm. The two largest-size actuators also employ caged ball-bearing chains in the ball-screw drive assembly, to ensure smooth, trouble-free operation under heavy load conditions.
All Festo EGSK and EGSP electric actuators feature four rows of ball bearings circulating within the loaded area of the moving carriage to maximise rigidity and help ensure a long service life. The ball bearings run between the honed grooves of the carriage and the linear guide until they are returned by means of the reversers in the end plates and the recirculation channels. The four rows of balls are arranged at a contact angle of 45 degrees, which means the guide carriage has the same basic load ratings in both radial coordinate directions; the actuator can therefore be used in any mounting position and can accommodate a wide range of load conditions.
EGSK and EGSP electric actuators are fully compatible with Festo's range of stepper and servo motors and controllers, and can also be used with third-party motors. Festo produces a comprehensive range of motor mounting flanges and couplings, as well as actuator-mounting plates and axial mounting kits. The company also offers optional cover kits for these actuators, plus a sensor rail kit that enables inductive position sensors to be attached to the left or right side of the actuator body. Festo has also developed a powerful PC-based software tool to help machine designers and other potential users make the best use of electric-drive technology such as the EGSK actuators.
This positioning drive software enables users to choose the optimum components for a complete, high-efficiency positioning system, and can be downloaded free of charge from the electric-drive technology page at Festo's website. Once a few application details have been entered, the software automatically calculates the ideal combination of electric linear axes, motors, gear units, controllers and software, from a widely coordinated product range. By specifying various project parameters, users can also obtain the load-characteristic values for the selected drive, quickly and reliably.
Modified PTFE Can Be Processed As A Thermoplastic
A structurally modified PTFE can now be processed as a thermoplastic. This gives designers a new range of freedom and enables hitherto impossible applications for this fluoropolymer.At the same time, part production is more efficient. Polytetrafluoroethylene (PTFE) is a high-performance material with a range of properties that have made it particularly suitable for challenging applications. By modifying the polymer, it has become possible to obtain a product, the newly developed Moldflon, that can be processed by thermoplastic techniques.
This material opens up further applications due to the freedom offered by thermoplastic shaping. It can overcome the conventional disadvantages of PTFE processing methods, particularly high material waste as a result of machining and poor surface quality. Due to the thermoplastic process ability of Moldflon, PTFE parts can be produced in a single operation. With traditional PTFE, at least three steps - pressing, sintering and machining - were necessary. The possibility of overmoulding individual parts that is now available can simplify product design.
Lean manufacturing replaces the previous complicated multicomponent solutions. For manufacturing PTFE coverings, processors have so far had two methods available. In isostatic pressing, the insert is embedded in the PTFE raw-material powder, which is then sintered. The surface usually only has to be finished by machining to meet the tight tolerance specifications. It is difficult to achieve smooth surfaces and challenging contours. Another way of producing the PTFE skin consists in prefabricating the individual parts from PTFE. Then the insert part is embedded in further shaping steps, or the PTFE components are welded to form the end shell contour.
Because Moldflon can be processed as a thermoplastic, the inserts can now be overmolded, greatly shortening the process chain. This results in a huge savings potential, particularly for large-scale production. Typical parts that are difficult to produce by conventional PTFE processes include joint capsules of ball-and-socket joints. Generating this outer skin from Moldflon not only requires a great deal of experience with the material behaviour, but also detailed technical knowledge about the production technology. Since Moldflon has a melting point of about 320C, melt temperatures of 360C and mould temperatures of about 260C are necessary.
The parts to be overmoulded must consequently pass through a pre-heating station before they are transferred to the cavity. If required, retaining the centring pins can be used to reduce the part tolerances. To prevent the plastic melt solidifying prematurely in the region of the pins, they are heated together with the surrounding components. During the injection, the pins are retracted, requiring special mould equipment. For top part quality, it is essential to coordinate all the relevant process parameters, from injection to demoulding. The sliding layers in the ball joints undergo steady, as well as intermittent, compressive loading during use and, in cars and trucks, they also experience high temperatures in the region of the drive components.
Fluctuating pressures and temperatures both require the material to have high compression resistance, but it should not have relaxation properties. This property combination is essential to minimise play during use. Frictional loads require the capsule material to have a low coefficient of friction and high abrasion resistance. The possibility of dry running during continuous operations reduces the maintenance outlay and system costs. What must be the composition of a material that can optimally meet these requirements? The structure of this semi-crystalline material is composed of lamellar crystallites and the amorphous zones between them. To achieve good mechanical strength of the material, the crystallites must be joined by sufficient numbers of tie molecules.
The tie molecules are anchored in various lamellae and tied together. The main difference from standard PTFE is that the lamellae in Moldflon are about a factor of 10 smaller than in conventional PTFE. As a result, comparatively small molecular chains can act as tie molecules. Short molecular chains in turn reduce the viscosity of the polymer melt, which is the prerequisite for thermoplastic processing. It is therefore possible to process Moldflon by the traditional methods used for thermoplastic, such as injection moulding, extrusion or transfer moulding.
Even melt spinning can be used to produce very thin fibres with an extremely smooth surface. The close-meshed crosslinking of the very small crystallites make the material extremely compression resistant compared to conventional PTFE and it therefore features low cold flow. Because of the molecular displacement within the crystalline regions, it can act as a dry lubricant similar to graphite, molybdenum disulfide or PTFE micropowders. This is the guarantee for the low-friction coefficient and the consequent low abrasion of this material. At normal processing temperatures, Moldflon has a corrosive effect on steel.
All the melt-contacting parts should therefore be made of corrosion-resistant metals. The screw and cylinder are made of materials such as Hastelloy C4 and Inconel 625, which are familiar for processing PFA (perfluoroalkoxy polymer) and FEP (fluorinated ethylene-propylene). The moulds and dies are made from nickel, nickel alloys and specially coated tool steels. Large runners are used because of the melt's shear sensitivity. For small injection moldings, the weight for the cold-runner system is often larger than the weight of the parts. Due to Moldflon's good recyclability, the sprue scrap can be easily returned to the product stream.
PTFE's properties combined with the possibility of thermoplastic processing open up a variety of new applications, which it has not been possible to cover in this way before. Although the product is still in the launch phase, a range of new system solutions are already emerging. The possibility of producing a large number of compounds additionally extends the range of the natural material. The possibility can be illustrated with reference to automotive applications. Moldflon components are primarily accessible via extrusion and injection moulding.
However, secondary processing methods such as blow moulding or thermoforming, as well as automatic machining of simple extruded profiles, are used here. The combination of traditional properties of PTFE - with the new process techniques of this material, such as injection moulding, transfer moulding and extrusion, but also thermoforming, blow molding or melt spinning - will allow completely new products to be produced economically on a large scale. It will also be easier to produce compounds based in Moldflon. This will allow the applications of this material to be expanded significantly beyond the existing limits of fluoropolymers.

Piezo Linear Motors Provide 20mm Travel RangesPI has introduced the N-216 Nexline high-load piezo linear motors - ultra-precision nanopositioning actuators that provide travel ranges to 20mm and push/pull forces to 600N (130lb). The operating principle is based on coordinated motion of a number of highly preloaded linear and shear piezo elements acting on a ceramic runner. Nexline Piezowalk drives can be used in ultra-precision manufacturing and semiconductor test equipment to astronomy and high-energy physics applications.
Their reliability makes them suitable for applications in difficult-to-access internals of instruments, where nanometer-realm adjustment and/or vibration cancellation are required. To promote long lifetime, the Piezowalk controller can reduce the operating voltage on the piezo elements to zero at any position without affecting the full holding force (up to 800N, 177lbs). The piezoceramic clamping and shear elements act directly on a moving runner coupled to the load.
For maximum velocity and long-distance movements, the runner can be driven in full step mode. Extremely uniform motion and constant velocity is achieved with the nanostepping mode. Combining long travel ranges with piezo-class precision, Nexline Piezowalk drives offer a high-dynamics analogue operation mode over smaller distances. Open- and closed-loop operation N-216 linear motors come in two versions for open- or closed-loop operation, as well as in two different load configurations.
Closed-loop versions are equipped with a linear encoder for direct position measurement of the moving runner. The encoder features 5nm resolution over the full travel range. In open-loop operation a positioning resolution to 30 picometers can be realised by use of the analogue operation mode.
Objet Geometries To Exhibit Connex350 3D PrinterObjet Geometries will showcase its latest 3D printer, the Connex350, at two customer events in France in March. Illustrating the benefits of high-performance rapid-prototyping technology, the 'A vitesse grand V' events will be hosted at Le Mans 24-hour circuit (9 March) and Actua GT Driving (11 March) in Lyon. The Connex350 maintains the Connex range's ability to produce 3D models by simultaneously printing multiple materials with different mechanical and physical properties.
Widely established through the Connex500, the Polyjet Matrix Technology enables two polymers to be printed as separate entities or mixed during printing. In this way it can simulate overmoulding or create different material characteristics such as variable shore hardness materials, due to Digital Materials. The Connex350 offers these capabilities at a lower investment, through its build volume of 350 x 350 x 200mm, while delivering the same performance as its larger counterpart.
The 'A vitesse grand V' events will introduce the features of the Connex350 through product demonstrations, technical explanations and case studies from customers on their experience of the base technology. There will be opportunities to discuss prototyping challenges with the Objet technical team and engineers, as well as explore other products from the Objet range.
