Abstract: A three wire power supply circuit is provided comprising a circuit for monitoring the integrity of the ground connection of the power supply circuit. A circuit element is provided in the line-to-ground current path which conducts when current flows in the line-to-ground current path and is nonconductive when the ground connection is poor or absent. A microcontroller monitors the output of the circuit element and operates a buzzer or a light emitting diode to indicate when the ground connection is poor or absent.

Abstract: Personal cleansing bar compositions which contain a fragrance-releasing complex and a bar carrier. The fragrance-releasing complex contains a hydrophilic inorganic porous fragrance carrier and a fragrance impregnated within the fragrance carrier. The ratio of the fragrance:fragrance carrier ranges from about 5:1 to about 1:10.

Abstract: The disclosure relates to removing impurities from hexafluoroethane (CF.sub.3 CF.sub.3), also known as Perfluorocarbon 116 (PFC-116) or Fluorocarbon 116 (FC-116), by using azeotropic distillation such that an overhead product consisting essentially of HCl-hexafluoroethane is formed, optionally combined with a phase separation step to break the HCl-hexafluoroethane azeotropic or azeotrope-like composition thereby permitting recovery of substantially pure hexafluoroethane. Unreacted hydrogen fluoride (HF) may be removed from hexafluoroethane during the above azeotropic distillation with HCl or alternatively by an azeotropic distillation wherein an HF-hexafluoroethane azeotropic or azeotrope-like composition exits overhead and substantially pure HF exits in the bottoms stream.

Abstract: A method for preparing moisturizing liquid personal cleansing compositions comprising preparing an encapsulated lipophilic skin moisturizing agent, mixing the encapsulated lipophilic skin moisturizing agent into a liquid personal cleansing matrix, and processing and packaging the resulting mixture. The final liquid personal cleansing composition product comprises a lipophilic skin moisturizing agent comprised of droplets having a particle size distribution such that at least about 10% by weight of the droplets have a diameter of greater than about 100 microns.

Abstract: A system for selectively providing power from a power source to a load to operate in an area for at least one occupant comprising a processing device for controlling the opening and closing of a relay connected between the load and the power source for energizing the load, and a sensor for detecting the presence of an occupant in the area. The processing device is programmable to close the relay in response to an output signal from the sensor for a period of time that can be of fixed duration, or a duration that is dynamically and automatically determined using sensor data relating to measured time between successive, detected occupant movements. In addition to a daylight inhibit function, the system is provided with color indicators and a tone generator to indicate various operating conditions and to guide a user entering selected system parameters, among other features.

Abstract: A method and apparatus controls the display of information for troops and vehicles in a simulated battlefield. Rounds of munition are fired into the simulated battlefield and the effects of such munitions are displayed on the troops and vehicles display devices. These display devices include character displays for troops and display screen for vehicles. The text character display may include such information as damage assessment, weapon type, miss distance and miss direction. A screen display may be used for a vehicle display. The screen display depicts similar information as for the text character display, but in a graphical representation via icons representing various battlefield effects.

Abstract: A forward observation officer (21) initiates a call for fire (33) on a particular target (20). The call for fire is received by a control center (30) which generates a precision guided munitions simulation message which is transmitted to all potential targets via a data link (31). The forward observation officer (21) then illuminates the target (20) with a laser designator simulator (22). Laser detectors (23) then determine that the target (20) has been illuminated. Processor arrangement (34) then determines that the target (20) was the correct one that was selected by the forward observation officer (21) and that the location of the precision guided munitions (29) is at the same location of the target (20). Processor arrangement (34) then indicates that the target (20) has been hit or missed.

Abstract: The invention is directed to a memory cell with a floating gate and a method for charging the floating gate using channel-initiated secondary electron injection (CISEI). In the device of the present invention, a positive bias voltage of about 1.1 volts to about 3.3 volts is applied between the drain and the source when introducing charge onto the floating gate. A negative bias voltage of about -0.5 volts or more negative is applied to the substrate and the source. The drain substrate bias induces a sufficient amount of secondary hot electrons to be formed with a sufficient amount of energy to overcome the energy barrier between the substrate and the floating gate to charge the floating gate.

Abstract: A magnetic resonance imaging apparatus includes a magnet assembly (10) for generating a temporally constant primary magnetic field through a central bore (14). The central bore is surrounded by a gradient coil assembly (30) including a dielectric former (32) and gradient coils (34, 36, 38) for generating magnetic field gradient pulses across the examination region. A radio frequency coil assembly (50) including a birdcage coil (52) is mounted inside of the gradient coil assembly and surrounding the examination region. A radio frequency shield (60) includes a dielectric sheet (62) having a plurality of first metal foil strips (72) defined on each surface. The metal strips are defined by etching or cutting gaps (70) in a continuous sheet of copper foil, leaving bridges (74) across the gaps adjacent opposite ends of the foil strips.

Abstract: A toroidal housing (18), such as a vacuum dewar, contains magnets (10, 12) for generating a temporally constant magnetic field through a central bore (14). Gradient coils (32, 42) are mounted around the bore defining a space therebetween. A radio frequency shield (78) is disposed radially inward from the gradient coils. Inside the radio frequency shield, an inner shimming assembly (60) includes a dielectric cylinder (62) having annular grooves around its periphery. Segmented ferrous material (66) is arranged in annular rings in the grooves. The ferrous material is segmented into small pieces electrically insulated from each other to limit radio frequency and gradient frequency eddy currents. A radio frequency coil (70) is mounted inside of the annular ferrous shims (66). Preferably, additional shim trays (50) which carry shims (54) are mounted in the space between the primary and secondary gradient coils.

Abstract: A manual tool for rolling and positioning a mass of material. More particular, for use with rolls of stratified materials having a central core. The tool when inserted into the central core of such stratified rolls articulates in a manner so as to allow a cleat member to grip the outer perimeter of the roll and thereby allows the workman to apply leverage to the mass causing rotation. Repeated articulated movements allows the tool to be operated in a ratcheting manner.

Abstract: An improved erase cycle for direct-viewing bistable storage tubes that substantially eliminates the bright flash characteristic of conventional erasure methods. As applied to the backplate of a meshless storage tube, the improved cycle suitably comprises two or more short (about 2 to 10 ms) fade positive pulses separated by a negative, decaying recovery pulse about 50-100 ms in length and optionally, a "dead time" of about 200 ms at the target operating level. The final fade positive pulse is followed by a longer recovery interval that gradually increases the backplate voltage to its previous operating level while the flood guns retain the storage phosphor in an erased, unwritten condition.
