Self-charging power cell converts and stores energy in a single unit
Georgia Tech researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. The advance could have military applications for troops who might one day recharge battery-powered equipment as they walk.

Engineer's Toolbox:
Maximizing steam turbine/compressor performance with precise torque monitoring at the coupling

Precise monitoring of turbo machinery performance with continuous torque-monitoring systems can be used to identify gradual efficiency loss, allowing a more focused maintenance scope to be developed to return the system to its optimum operation and efficiency. A system of this type was recently installed on a cracked-gas compressor train at Qenos Olefins in Australia to determine the causes of a power limitation.

Expanded line of low-load gaskets
Garlock Sealing Technologies has expanded its line of low-load gaskets with the addition of its 3504 GYLON STRESS SAVER for industrial applications and the 3505 GYLON STRESS SAVER for potable water applications. These gaskets are designed to seal lightweight metallic, plastic, and fiberglass flanges that cannot provide the proper loads required to compress conventional fiber or PTFE gaskets. The molded, raised, concentric ribs allow for a more concentrated gasket load, creating a tighter seal with less torque on both flat and raised face flanges. The gasket material, 100% GYLON PTFE with glass microspheres, provides superior cold-flow and creep resistance, eliminating the need for frequent retorquing. The field-proven Blue GYLON material gives the gaskets chemical resistance and high-temp (-450° to 500° F) and pressure capabilities.

ERD actuator with reverse-parallel motor mount creates compact, flexible package
Tolomatic's ERD electric cylinders are now available with a reverse-parallel motor mount that creates a more compact and flexible package. The new option reduces the length of the Tolomatic ERD actuator while increasing mounting flexibility and motor selection in electric actuator applications. Designed as an alternative to pneumatic cylinders and as an option for automating manual processes, the economical ERD rod-style electric actuator is ideal for product changeovers, pick-and-place, pressing, diverting, heat-staking/sonic welding, and more.

Polymers that can reduce weight, improve reliability
VICTREX 90-Series polymers are widely specified in applications like brackets, clamps, stand-offs, and fasteners for the aerospace industry due to the significant weight savings achieved that increase the fuel economy of the aircraft. Automotive bearings and bushings made from PEEK thermoplastics also help to reduce vehicle weight and have no creep deformation after running at 5,000 rpm continuously for more than 2,000 hr, which improves the overall fuel economy and reliability of the vehicle. In electronics, VICTREX 90-Series grades are used in connectors, capacitors, sensors, bobbins, and switches due to lower outgassing, increased ductility, higher knit line strength, and the ability to withstand the lead-free soldering process, which can reach temperatures up to 280° C (536° F).

NASA's next rover is chock full of 3D-printed parts
NASA engineers are using 3D printing to build a next-generation, two-person rover to support humans exploring other worlds, such as asteroids and Mars. Designers of the galactic SUV used fused deposition modeling (FDM) technology from Stratasys to create one-off, working prototype parts quickly and efficiently.

DARPA developing new amphibious transporters for disaster relief
Take a 1/5-scale demonstrator of the Captive Air Amphibious Transporter (CAAT) for a spin. The CAAT has air-filled pontoons on a tank tread-like design, enabling it to carry containers over water and directly onto shore. The vehicle is part of DARPA's Tactically Expandable Maritime Platform (TEMP) program, which seeks new sea and air delivery systems to enable direct support to disaster zones from offshore container ships. All technologies developed under TEMP are transportable using standard 20- or 40-ft commercial shipping containers. This technology demonstrator is jointly funded with the Office of Naval Research, which is looking at it for potential use as an amphibious transport for the Marines/Navy.
