Abstract: A hybrid engine, having a plurality of coupled expansible chamber devices, preferably a piston in a cylinder, each capable of operating in any one of an internal combustion mode, an air pump/compressor mode and an air motor mode. The modes are controlled by a microcontroller which controls the valves, ignition source and fuel source. The mode for each expansible chamber device is computed and independently selected by the microcontroller and the combination of modes at any instant is switched to optimize engine operation for the operating conditions at that instant.

Abstract: A hollow evaporator is disposed in contact with the upper surface of the CPU. Heat from the CPU is absorbed by the evaporation of the refrigerant. The vaporized refrigerant ascends through the vapor flow channel by convection, flows into a condenser located above the evaporator, and radiates heat to be liquefied. The liquefied refrigerant flows down by its own weight through the liquid flow channel and returns to the evaporator. This circulation is repeated in this manner.

Abstract: A child car seat is designed for attachment to an automobile seat. The child car seat includes two sets of restraining guides through which a belt is threaded to install the child car seat to the automobile seat. One set of restraining guides is for positioning the child car seat to the automobile seat in a forward-facing orientation, and another set is for a rearward-facing orientation. The installation belt has two ends and an intermediate region extending between the ends. A length adjustor is engaged to the intermediate region, and a fastener is attached to each belt end. Each fastener detachably connects to cooperating devices on an automobile seat.

Abstract: A hand tool has a ground-piercing probe, which is manually insertable in the soil. The probe has a chamber in which an inductor is positioned and connected to metal detection circuitry. A pulse generator applies current pulses to an inductor for inducing eddy currents in a buried target object. After the pulse terminates, the decaying coil voltage is sampled at different times to detect both the presence and range of the object, as well as the type of metal in the object. The coil voltage samples are applied to signaling circuitry, which provides an audible signal which is a series of bursts of an audio tone. The pitch of the audio tone signals the presence, range and bearing of the buried metal object, while the pulse rate of the bursts signals the metal type. Signal variations resulting from temperature changes when the probe is inserted into soil are compensated for by detecting a signal proportional to the coil current during the pulse and subtracting a scaled portion of that signal from voltage samples.

Abstract: A fluent material containing and dispensing apparatus including a hopper having four sidewalls. A tube mounts to one of the sidewalls, and an auger extends from one end of the tube to the opposite end of the hopper, driving material in the hopper through the tube when the auger is rotated. A flexible hose is mounted to the underside of the tube and material in the tube pours into the hose, which can be kinked to slow or stop flow of material. A gap is formed between the outer surfaces of the auger and the tube wall. A radially inwardly extending flange can be mounted to the tube wall to slow the flow of material through the gap. Alternatively, a compressible sleeve can be mounted in the gap between the outer surfaces of the auger and the tube wall extending a substantial length of the tube.

Abstract: A Triac and a phase-locked loop are used to control the amplitude of reciprocation of an AC linear motor. The phase locked loop generates a square wave that is synchronized with an AC power source but is substantially isolated from electrical noise on the power source. The phase of the square wave is varied with an amplitude control signal, and Triac firing pulses are generated at the transitions of the square wave.

Abstract: Disclosed is a method of generating magnetic centering force on the permanent magnets of a reciprocating permanent magnet motor or generator, by allowing the ferromagnetic structure of the machine to saturate magnetically when the permanent magnets are near the ends of their travel.

Abstract: A self-adhesive laminate for sealing window frames includes an aluminum layer having a first side and a second side, a polyester layer adhered to the first side of the aluminum layer, an adhesive layer adhered to the second side of the aluminum layer, and a release paper overlying the adhesive remote from the aluminum layer. This laminate reduces or eliminates the overheating problems common in prior art tapes.

Abstract: A revolution threshold regulator and/or toggle switch has a first and a second fixed phase source of alternating current having a frequency proportional to the revolution speed of a rotor of an internal combustion engine. A trigger device scans the alternating currents to emit a control signal at a revolution threshold above or below a preset revolution threshold. The trigger device has a timer module which cooperates with one of the alternating current sources through a trigger charge element which can be discharged via at least one discharge path to create a control signal. The trigger charge element, as it discharges, sends a control current through a series Zener diode in a blocking direction to the control signal output.

Abstract: A hand tool has a handgrip attached to a ground-piercing probe, which is manually insertable in the soil. The probe has a chamber in which at least one inductor is positioned and connected to metal detection circuitry. The preferred circuitry has a pulse generator applying current pulses to an inductor for inducing eddy currents in a buried target object. After the pulse terminates, the decaying coil voltage is sampled at different times to detect both the presence and range of the object, as well as the type of metal in the object. An asymmetric magnetic field pattern about the probe is aligned with a direction pointing indicium on the handgrip and provides directional sensitivity. The coil voltage samples are applied to signaling circuitry, which provides an audible signal which is a series of bursts of an audio tone. The pitch of the audio tone signals the presence, range and bearing of the buried metal object, while the pulse rate of the bursts signals the metal type.

Abstract: A candle and method of making the candle. The candle includes a core surrounded by a combustible material and a fill composition. The combustible material surrounds the core. A wick extends downwardly a selected distance from the top of the core. The core is partly surrounded by a translucent sleeve which may include holes. In this way, the risk of the combustible material catching fire is reduced.

Abstract: A wick trimmer includes a gauge for assisting a user in trimming a candle wick to an appropriate length. The wick trimmer is adapted to be of a shape and size to allow a user to trim the wick within a votive holder, hurricane lamp, or the like without removing the candle. The gauge may be fixedly, rotatably, or slidably attached to the cutter and extends transversely of the blade of the cutter.

A central transceiver station is coupled to a base station controller and has a plurality of decentral transceiver stations surrounding and coupled to the central transceiver station. Groups of adjacent decentral transceiver stations are grouped in respective cell areas. All of the decentral transceiver stations in each cell area are allocated the same transmission frequencies, but the frequencies of each cell area are different from the other cell areas in the cell region.
