Pressure-Compensated Flow Control Valve

Beswick Engineering (Greenland, NH) has released the PCFCD-1N1, an ultra-miniature pressure-compensated flow control valve with low-friction diaphragm. The device is designed to maintain a constant flow rate, which the customer can adjust, regardless of upstream or downstream pressure variations. It works with incompressible fluids and gasses, but is primarily intended for the control of liquids. The pressure regulation is accomplished with a low-friction diaphragm mechanism.

Shaft Grounding Ring

The AEGIS SGR™ Conductive MicroFiber™ Shaft Grounding Ring from Electro Static Technology (Mechanic Falls, ME) is suitable for predictive maintenance programs on VFD-controlled AC and DC motors. By protecting bearings from electrical damage, the SGR may extend motor life by preventing bearing noise, downtime, and motor repairs and replacements. Preventing shaft current damage, the AEGIS SGR provides predictive/ preventative maintenance programs for motor repair shops, maintenance contractors, HVAC service contractors, and in-house maintenance departments. The SGR’s conductive microfibers work with no friction or wear, are unaffected by dirt and grease, and last for the life of the motor, regardless of the RPM. The SGR can be mounted on any NEMA or IEC motor and provides clearance for motors with shaft shoulders, slingers, bearing caps, or end-bell protrusions.

Origin 8

OriginLab Corp., Northampton, MA, has announced Origin 8 Windows-based data analysis and graphing software that operates around a revamped workbook space, which allows results of an analysis to be placed into a worksheet within a raw data’s workbook. Parameter values, statistics, and related analysis graphs are available whenever looking at the original data. A new multi-sheet workbook feature keeps all related data, analyses, and graphs together. Sheets can be moved, added, inserted, or deleted. Workbooks in the new version also contain a new feature that allows users to embed graphs and images within cells to create a custom report. Another new feature called Sparklines allows for a special type of embedded graph found within worksheet column headers. Column Sparklines provide brief profiles of the column’s data, providing users with an at-a-glance profile of the data in a given column. The aspect ratio of column Sparklines can be changed to show more data trends by changing the column width and/or row height. A graph can be copied to the clipboard as a Sparkline to display a small, word-sized graphic within text documents.

System Locates Passengers Who Contaminate Airline Cabins

Researchers at Purdue University have developed a system that uses mathematical models and sensors to locate passengers releasing hazardous materials or pathogens inside airline cabins. The system can track a substance to an area the size of a single seat. The technique could enable officials to identify passengers responsible for the unintentional release of germs, such as contagious viruses, or the intentional release

Karen Whitley, Expandable Structures for Exploration Task Lead

NASA Langley Research Center, Hampton, VA Karen WhitleyNASA plans to return to the Moon by 2020. For a sustained lunar presence, however, astronauts need habitats that can support them and their experments. To this end, researchers at NASA Langley, working with NASA contractor ILC Dover (Frederica, DE), are developing the “planetary surface habitat and airlock unit,” a prototype inflatable structure that could be deployed on the lunar surface. Karen Whitley is the project lead.

Battery Power Source Options for Mission-Critical Applications

Selecting power source technology for mission critical devices is crucial to ensure success. Whether it is a monitor at the bottom of the ocean, a drill system at 30,000 feet into the Earth’s crust, or hand warmers on an astronaut in Earth orbit, the cost of failure in these situations far outweighs the cost of a battery. Equipment used in these and other mission- critical situations must perform under environmental conditions that would destroy most commercially available components and energy sources. Every element must be capable of operating in environments where extremes in temperature, pressure, shock, vibration, and corrosive exposure are the norm. Selecting batteries for these vital activities must include consideration for the high level of reliability and performance required to ensure these significant and often costly programs stay on target.
