Panaflo® axial fans from Panasonic Industrial Co. feature a sealing process that protects circuitry, pc-boards, and connections against invasive moisture, dust, and high ambients. The fans are available for operation with a choice of signal outputs, and feature low noise and minimum vibration. Operating temperature range is -10 to 70C, and all sizes are available in either 12 or 24V dc models.
Series RVDT anti-siphon valves from Plast-O-Matic Valves Inc. prevent gravity-induced siphonage from storage tanks, and remain closed under the pressure created by the presence of liquid in a tank and piping system, but open under pump pressure. In chemical process applications, the anti-siphon valve protects a system from unwanted flow through a pump due to negative pressure in a pipeline. The RVDT actually closes tighter under the presence of vacuum at the valve outlet; yet it opens and allows chemicals to enter the system under controlled pumping, the company says.
Cryogenic valves from Valcor Engineering Corp. are for critical flow control of liquid nitrogen and liquid carbon dioxide. The valves provide maximum cryogenic fluid throughput with minimum pressure drop, the company says. Applications include coolant controlled for environmental chambers, and liquid and gas chromatography.
Flow tubes from Andrews Glass Co. are for use in equipment and instrumentation that require precise flow control. The company uses shrinking equipment to produce flow tubes to exact specifications, and can manufacture tubes to handle gas flows from 0.1 ml to 20l .
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
