Bray Controls has unveiled the Series 92/93 actuator, which features two independently adjustable travel stop screws and a cam on the output shaft to permit precise bi-directional adjustment of actuator movement in both open and closed positions for quarter turn valves. Available in two versions—double acting and spring return—the rack-and-pinion, opposed-piston actuator are intended for on-off and throttling applications. It offers a maximum pressure of 140 psig and temperature ranges of -40F to +200F. For more information, go to www.bray.com
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
