The Timken Co. is using a $1.4-million grant from the US Department of Energy to develop an online ultrasonic measurement system that increases the efficiency of manufacturing seamless steel tubing. The new manufacturing process uses a laser-ultrasonic system for providing on-line measurement of wall thickness and eccentricity of steel tubing for manufacturing control. According to the US Department of Energy, the system improves productivity of seamless mechanical steel tubing by 30 to 50% while reducing energy consumption and emission of pollutants. How? First, consider that current methods require stopping production runs for manual measurement. Machinery adjustments for each run result in a loss of approximately three of ten tubes made. "And while you stop the machinery and make adjustments three or four times, your plant sits idle," says Robert Kolarik, an engineer and project manager for the Timken Co. "The new online ultrasonic measurement method eliminates the need for stopping the machine for manual measurements. "Just like traditional ultrasound, we use sound waves. Knowing the acoustic velocity of the steel allows us to determine the wall thickness and eccentricity," he says. Scrapped tubes resulting from out-of-tolerance specifications are eliminated.

The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
