Molded Nylon Special Standard Round Spacers
Micro Plastics announces a new product line of Special Standard Round Spacers. The new line of molded nylon round spacers includes over 250 sizes, with diameters of 1/8" through 1 1/2" and lengths from 1/8" to 2 3/4". These tough, resilient spacers can be used in a variety of assemblies. Useful in electronic and electrical applications, they may also be used as bushings, bearings, rollers, gliders, and bumpers. They are resistant to vibration, abrasion, and corrosion; are electrically insulating; and have a high strength-to-weight ratio.

A Robot Coming Out of its Cage
Universal Robots has reinvented industrial robotics with lightweight and flexible robot arms. The Danish-designed robots automate production in all industries -- even in SMBs that regard automation as prohibitively expensive, cumbersome, and difficult to integrate. Based on risk assessment, the robot arms can operate with no safety guarding and are easily moved around to complete the most detailed tasks. Programming is done through an intuitive touch screen, eliminating the need for skilled programmers. Sold in over 50 countries worldwide, the average ROI of a UR robot is three to eight months.

Image - Rotary ball spline technologies and the effective differences of two rotational nut technologies
Rotary ball spline technologies and the effective differences of two rotational nut technologies
Before you specify a rotary ball spline, ask the question, "Should the rotary spline nut be riding on angular contact ball bearings or crossed roller bearings?" Naoki Yamaguchi, assistant technical manager, NB Corp. of America, answers this and a host of other considerations.

U.S. Army researches advances in fire control technology
U.S. Army researches are working on a two-phase small-arms fire control project to help warfighters make more accurate shots from longer distances. Combining a new laser range finder with software that can pick out and track human targets, the engineers and scientists have demonstrated the capability to fire and hit the targets accurately from 1,200 m and further.

New technology may double radio frequency data capacity
A team of Columbia Engineering researchers has invented a technology -- full-duplex radio integrated circuits (ICs) -- that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies.

NASA tests experimental wing for aircraft powered by electric motors

The arrival of a unique experimental demonstrator at NASA Armstrong Flight Research Center on Feb. 26, 2015, may herald a future in which many aircraft are powered by electric motors. The Leading Edge Asynchronous Propeller Technology (LEAPTech) project will test the premise that tighter propulsion-airframe integration, made possible with electric power, will deliver improved efficiency and safety, as well as environmental and economic benefits.

Mike Likes:
Achieve maximum flexibility with electroformed bellows couplings

Electrodeposited bellows technology offers the best combination of flexibility and strength among coupling technologies. Servometer flexible shaft bellows couplings offer seamless construction with maximum flexibility, and handle angular misalignment up to 31° and parallel misalignments up to .076". Servometer bellows couplings exhibit low windup due to the bellows' radial rigidity, and low side thrust due to its lateral flexibility. Applications include encoders, servos, actuators, robotics, CNC machine tools, and more.

Image - Product: Hydraulic motors generate 4X more torque
Product: Hydraulic motors generate 4X more torque
Dayton Lamina hydraulic motors feature a unique, three-moving-part design that allows four times more torque to be produced at one-quarter the speed without gear reducers. With torque ratings comparable to larger motors, they save size, weight, and cost over larger, similarly rated motors. These low-speed/high-torque, high-speed/low-torque motors feature instant forward and reverse. Six motors are available with a torque range from 0 to 656 in-lb. and speeds from 0 to 2,255 RPM, providing the selectivity required to meet exact project parameters. These proven models are ideal for a wide range of applications, including conveyor drives, hose reel extraction, fan drives, pipe valve openers, thread core removal for plastic injection molding, box sealing equipment, and more.

NASA's giant crawlers turn 50 years old, pivot toward future exploration

NASA's crawler-transporters, two of the largest vehicles ever built, have carried NASA rockets and spacecraft to the launch pad for the last 50 years. Now these mega machines are being beefed up to carry NASA's Space Launch System (with the Orion spacecraft atop) and a whole lot more to begin even more ambitious space exploration missions.

Modeling mechanical applications in COMSOL Multiphysics
COMSOL Multiphysics is an ideal software solution for modeling mechanical applications and analyzing the multiple interacting physics affecting them. Structural mechanics, nonlinear material models, and geomechanics are just some of the many mechanical applications you can model with the software. Predefined interfaces, packaged within the COMSOL software, enable you to investigate multiphysics phenomena, such as electromechanics, acoustic-structure and fluid-structure interactions, and thermal and electrical contact analysis. Learn how COMSOL Multiphysics can help you streamline the design process and optimize your mechanical designs.
