Abstract: A method of eradicating pests by the controlled application of heat for a predetermined period of time.

Abstract: An apparatus and method for detecting faults and providing diagnostic information in a refrigeration system comprising a microprocessor, a means for inputting information to the microprocessor, a means for outputting information from the microprocessor, and five sensors.

Abstract: The performance of a refrigeration system is often reduced due to insufficient refrigerant charge or due to the use of an inverter compressor. The performance loss is associated with the operating condition, which is not at the optimum, thus yielding less than the maximum EER (energy efficiency ratio). A vortex generator restores the optimum operating condition in the refrigeration system with insufficient refrigerant charge or using an inverter compressor.

Abstract: A linear switch having 360 degree circumferential activation is provided. The switch includes first and second resilient strips separated by an actuator that defines two separate longitudinal channels. A pair of conductive strips, separated by perforated foam, extend the entire length of each channel. An external force applied anywhere along the exterior length or perimeter of the switch will activate it.

Abstract: A low-cost, easy to manufacture and maintain pressure responsive switch. The switch includes a pressure responsive diaphragm made from latex rubber that is mounted in a housing base. An annular groove in the housing base communicates with an annular shoulder in a housing cover to compress an O-ring for forming upper and lower chambers, sealing the housing and securing the diaphragm.

Abstract: An apparatus for lifting pipe including an arm having a substantially rectangular cross-section, and a substantially cylindrical body portion pivotally mounted to the arm. The apparatus is designed to be inserted into the standard lift port of a pipe section. In addition, a handle may be attached to the arm to more easily carry and to guide the apparatus into the lifting port. The apparatus allows a single worker to quickly and efficiently lift pipe sections, while reducing the possibility of injury.

Abstract: A portable containment apparatus for field use in containing liquids from vehicles and the like. The containment apparatus is especially designed to contain wash water run-off and includes a plurality of side members for defining a predetermined wash area, an integral floor and wall for containing the wash off, a sump for collecting the wash off, a sump pump for removing the liquid from the containment area to a remote container for later disposal.

Abstract: A rigid ultrasonic radiating plate system assembly designed for fastening to bottom/planes of an ultrasonic cleaning tank. As an initial sub-assembly, the plate has selected threaded bolts/studs which are fitted/welded in a pattern perpendicular to the bottom of the plate. This plate sub-assembly component is fitted through the selected tank plane (bottom/wall), by simultaneously matching the entire bolt/stud hole pattern through to the outside of the tank and on the inside of the tank against the surface of the bottom/wall.

Abstract: An improved wall plate incorporating an electroluminescent lamp for providing illumination to the immediate area proximate the wall plate. The electroluminescent (EL) panel is activated and deactivated by a photoconductive cell, in response to the intensity of ambient light falling on the wall plate. A further embodiment provides for an easily accessible regulating means for regulating the intensity of the light emitted by the EL panel.

Abstract: A teleradiology system for sending the raw data from a complete patient study to a remote location for a radiologist to make a final diagnosis. The system consists of two segments, a sending segment and a receiving segment. The sending segment consists of a universal floppy disk reading unit capable of reading raw data from a radiological device, (e.g., CAT Scanner, Nuclear Medicine Imaging device, Magnetic Resonance Imaging device, and the like) a personal computer, and a high speed modem. The receiving segment consists of a high speed modem to receive the data from the sending segment, a personal computer to control the receiving and manipulation of the data, and a high resolution monitor to view the images. The segments communicate through the modems and over existing telephone systems. At the remote location, the radiologist has the raw data and the capability of utilizing true windowing functions and true density values.
