Abstract: A rotating machine valve health monitor. Aspects of the valve monitor include instrumenting each valve of a reciprocating compressor, or other rotating machine, with a sensor capable of detecting at least vibration and instrumenting the crank shaft with a sensor capable of detecting at least rotation. A controller directly monitors the operation and condition of each valve to precisely identify any individual valve exhibiting leakage issues rather than only identifying the region of the leakage. The valve monitor uses a relatively high frequency stress wave analysis technique to provide a good signal-to-noise ratio to identify impact events indicative of leakage. The valve monitor uses circular waveforms of vibration data for individual valves to identify leakage by pattern recognition or visual identification. The valve monitor provides ongoing data collection to give warning of predicted valve failure and scheduling of preventative maintenance for failing valves.

Abstract: A three-phase vacuum interrupter switch assembly for power distribution systems comprises an outer case having at least one window, a plurality of internal disconnect switch assemblies, and a plurality of vacuum interrupter bottle switch assemblies within the case. Each vacuum interrupter bottle switch is coupled in electrical series with a corresponding internal disconnect switch assembly. Because the open/closed state of a bottle switch is not directly observable owing to its sealed interior, a direct visible indication of the state of the three-phase vacuum interrupter switch assembly is provided by a visually detectable contact rod for each internal disconnect switch that is visible through the case window. To prevent potentially serious damage caused by arcing between the contacts of the internal disconnect switch, the internal disconnect switch is prevented from opening or closing when the bottle switches are closed. The case interior is preferably free of oil and/or SF6 gas.

Abstract: An enclosed insulator assembly has a generally cylindrical polysiloxane body, a tubular Durethan® core with upper and lower terminals, Multilam™ contacts within the terminals, an arc-quenching tube, and a manually removable handle. Entrance holes in the body accommodate the coupling of external cables to the terminals. A threaded cylinder positioned on the handle's interior accommodates one of an interchangeable cutout fuse tube assembly and disconnect tube assembly and permits the assembly to be inserted into the core as the handle is positioned on the body. Both assemblies have top and bottom fittings with O-rings that prevent weather corrosion between the fittings and terminals. A grooved load interrupter is attached to the bottom fitting of the assemblies to suppress arcing when the assembly is pulled out from the body.

Abstract: A method and a device for the detection of trinitrotoluene (TNT) in efflu water from the purification apparatus of ammunition plants is described. The tube detector utilizes a basic oxide section to convert the TNT to its Meisenheimer anions, followed by an alkyl quaternary ammonium chloride ion-exchange resin which collects the colored anions. The length of the resultant stain is proportional to the concentration of TNT in the water.

Abstract: A method for analyzing water for .alpha.-trinitrotoluene comprising the ss of allowing the water to flow over an ion exchange resin which contains a quaternary ammonium group and observing to determine whether or not a chemical reaction takes place.

Abstract: A signal device combining a fluorescent or phosphorescent light tube and a ovel base to be thrown or dropped from a vehicle as a warning marker. The light tube may be of the chemically actuated type and the base preferably has four pivotally attached resilient legs serving to ensure that the device will assume an angular position of about 45.degree. when dropped.
