Pneumatically-driven vacuum pumps. The Low-Pressure Mini Chip vacuum pump series is designed to handle low or fluctuating compressed air pressures. These pumps, at an inlet pressure of only 55 psi, provide down to 24.1 in. Hg of vacuum. The multi-ejector pumps are quiet, easily installed and virtually maintenance-free. Offered in several mounts, their small size permits use in end-of-arm tooling applications, or wherever space is at a premium. PIAB Vacuum Products. Rockland, MA. http://www.piab.com

Ultra-high molecular weight plastic. GAR-DUR is abrasion resistant and offers a low coefficient of friction, reducing clean-up time as materials do not stick to its surface. It is self-lubricating and has high impact resistance, becoming work-hardened in the course of use. GAR-DUR also resists alkalis and all acids, except for concentrated sulphuric and nitric acid. It is stable over temperature extremes from -460°to 180°F. Garland Manufacturing. Saco, ME. http://www.garlandmfg.com

Right Angle Servo Gearbox. The Dyna Series servo gearbox uses hypoid gearings to deliver high torque throughput and positioning accuracy for high-dynamic servo applications. Precision-ground gears in the single-stage unit allow efficiencies up to 96% and provide for low backlash and noise. Eight ratios from 3:1 to 15:1 are offered with one or two output shafts, or with a hollow bore configuration. Taper roller bearings handle high loads.

Peristaltic pump. The MicroPeri pump with 3mm ID silicone tube delivers up to 30 ml/min, and can provide pressure up to 15 psi. The unit is available with AC or DC gearmotor drives -- the DC motors are for 6, 12 or 24V supplies. This is also for MicroPeri models with 1.6mm ID tubing. Peristaltic pumps are ideal for moving hard-to-handle fluids, because only the tubing comes in contact with the material being pumped. Small Pumps Inc. Arlington, TX. http://www.smallpumps.com

Supercapacitor. The Best Cap line of supercapacitors is based on an aqueous chemistry (rechargeable hydrogen ion solid state). This technology is ideal for high power pulsing, and is designed for use in hand-held and mobile communications equipment. RHISS also results in an environmentally friendly non-hazardous material, providing a significant advantage over other lithium or nickel based power sources. AVX.

Conductive urethane. Durethane C urethanes are available in a range of solid and foam formulations. Applications where electrostatic dissipation or tribocharge management are required are ideal for this material. It is a machinable, thermoset polyurethane that contains low percentages of conductive additives (0.1 to 10% by weight) to control the flow of electrical charges while preserving the strength, resilience, thermal stability and life of the material.
