Abstract: A downhole pump comprises a pump cylinder driven by a pneumatic cylinder. A compressor compresses air and delivers compressed air to the pneumatic cylinder under the control of first and second trip valves and a pilot valve. The trip valves control the pilot valve so that it alternately delivers the compressed air above and below the pneumatic cylinder piston to reciprocally drive the piston. The pneumatic cylinder piston connects to the pump cylinder via a pair of push rods to drive the pump cylinder piston to pump water from the well to an above-ground reservoir.

Abstract: A microwave signal is generated from a fixed source across a fixed path to trigger individual FM transmitters in passing objects such as race vehicles. A vehicle transceiver then sends an omnidirectional specific frequency FM radio carrier signal with a tone imposed to a console and a portable remote receiver. As the FM signal and tone are detected and decoded by the console receiver, data word is sent to a scoring computer which displays the lap of that particular vehicle and the current order of all vehicles.

Abstract: A surface mount soldering/de-soldering tip holder includes a base having recesses or pockets formed therein that include at least one wall configured and sized to cooperate to a side surface of the tip. A cover plate having apertures formed therethrough is positioned on the base such that the apertures are aligned with the recesses in the base. Each aperture includes a convex portion for seating the shank of a soldering/de-soldering tip, while the portion of the cover plate adjacent to the convex portion extends over a portion of the respective recess to form a shelf. The shelf cooperates with the shoulder of a soldering/de-soldering tip once the tip is properly positioned in the recess. To remove a tip that is frictionally secured within a soldering iron adapter, the tip is inserted into one of the recesses formed in the base and positioned so that its shank is seated against the portion of the cover plate that forms the boundary for the convex portion of a respective aperture.

A preferred oral dosage form according to the invention comprises a capsule or other dosage form having a dimension above 2 mm and that contains one or more of the said units. The density of each unit is preferably at least 2.5 and usually at least 2.7 g/ml and can conveniently be achieved by including at least 50% by weight of a weighting agent such as barium sulphate.

Abstract: A carrier for electronic components which generate heat during their operation, such as high power semiconductors, is disclosed. The carrier includes complementary ends which are designed to permit the second end of a first carrier to abut and overlap the first end of a second carrier to conserve space when more than one carrier is mounted on a substrate containing an electronic circuit. Preferably each end of each carrier has an aperture bored therethrough to allow the carrier to be mounted to the substrate with fasteners such as screws. The apertures are located so that the aperture in the second end of a first carrier aligns with the aperture in the first end of a second carrier to permit a first and a second carrier to be fastened to the substrate with a common fastener passing through the aligned apertures. Similarly, the aperture in the second end of a second carrier is positioned to align with an aperture in the first end of another carrier.

Abstract: The toy action figure includes a body having one leg mounted for rocking movement toward and away from its other leg. The figure also includes one arm mounted for swinging movement about a generally vertical axis provided by a ball member on said arm and a ball cup integral with the figure's body. A motion-converting mechanism is contained within the body which mechanism comprises an actuating lever which is rocked when said one leg is rocked. The actuating lever includes a triangularly configured cam at its upper end having an angled cam edge which engages against an edge on a panel. The panel is integral with a transmission lever that constitutes an inverted T-shaped member and which pivots abouts its lower T-shaped end when the cam edge acts against the panel edge so as to cause a generally vertical pin of the upper end of the transmission lever to force in an angular direction a lever arm integral with a ball member on the arm to be swung.

Abstract: An impact responsive toy vehicle in which two separable halves each carrying surface engaging wheels are connected together to provide a vehicle supported on the surface engaging wheels. A torsion spring biases the joinable ends of the two halves to separate and each flip over. The parts are retained together by a connecting latch that is disengageable by a slidable lever that moves in reponse to a force on an extending front bumper. One half carries a rotatable lock including a lug that cooperates with an abutment on the lever to lock the trigger lever against sliding movement in response to impact on the bumper. Fail-safe combination of the two parts rendering the impact responsive feature totally inoperative is accomplished by assembling the parts together with the arm of the torsion spring received in a recess on the underside of the chassis of the other half.
