摘要:
A pneumatic gauge and pressure control device includes a pneumatic gauge that is manually movable from a neutral position to: (i) a fill position for compressed air to flow from a compressed air source into a system; or (ii) a vent position for compressed air to be vented from the system. The pneumatic gauge can rotate or slide from the neutral position to the fill and vent positions. A method for controlling a flow of compressed air with respect to a pneumatic system includes manually moving a pneumatic pressure gauge from a neutral position to a fill position to cause compressed air to be communicated from an associated compressed air source into the pneumatic system and/or moving the pneumatic gauge from the neutral position or from the fill position to a vent position to cause compressed air to be vented from the pneumatic system.

A piston assembly used in forming a gas spring assembly includes a first piston member and a second piston member telescopically engaging one another and capable of axial displacement relative to one another between collapsed and extended conditions. The first piston member includes a mounting end and the second piston member includes a flexible wall-engaging end. The first and second piston members arranged such that in the collapsed condition the mounting and flexible wall-engaging ends are disposed a first distance from one another and in the extended condition the mounting and flexible wall-engaging ends are disposed at a second distance from one another with the second distance being greater than the first distance. A gas spring assembly and suspension system utilizing such a piston assembly as well as a method are also included.

A device for measuring near forward scatter caused by particulate matter in a fluid is disclosed. The device comprises, according to various embodiments, a transceiver and a reflector. The transceiver includes a light source and a detector. The reflector is positioned opposite the transceiver so that at least a portion of the fluid is present between the transceiver and the reflector. The reflector includes a front portion facing the transceiver. Optical energy from the light source incident upon the reflector is reflected towards the transceiver as a return beam of optical energy, wherein the detector senses primarily optical energy of the return beam that is scattered over a range of near forward angles by particulate matter in the fluid.

摘要:
A thin window that stands off atmospheric pressure is fabricated using photolithographic and wet chemical etching techniques and comprises at least two layers: an etch stop layer and a protective barrier layer. The window structure also comprises a series of support ribs running the width of the window. The windows are typically made of boron-doped silicon and silicon nitride and are useful in instruments such as electron beam guns and x-ray detectors. In an electron beam gun, the window does not impede the electrons and has demonstrated outstanding gun performance and survivability during the gun tube manufacturing process.
摘要:
A gas sampling system utilizes small sample vacuum transport to reduce the dew point of the sample. A vacuum pump maintains a substantial vacuum on the sampling system causing a sample, drawn at a rate less than a liter per minute, to be drawn and transported under partial vacuum for analysis. A dryer can be placed near the sampling probe to further reduce the dew point prior to the vacuum transport. The dew point of the sample is affected by both the dryer and the degree of vacuum transporting the gas mixture. As such, the dew point can be varied indefinitely by any reasonable combination of moisture removal by the dryer and vacuum pump strength.
