  • Patent number: 5439038
    Abstract: An apparatus for repressurizing a partially emptied carbonated beverage bottle, comprises a stationary pumping station mountable against a wall or under a kitchen cabinet, and a set of bottle caps adapted for use on the pumping station. The station includes a pump operated by pushing a movable front panel section, a filling slot equipped with a air-supplying cannula, and a slot for holding the set of caps. Each cap has a resiliently self-sealing opening designed to be penetrated by the cannula when the bottle is inserted into the filling slot, and a pouring orifice closed by a thumb-activated and spring-biased stopper.

  • Patent number: 5434454
    Abstract: Proximity switches and circumferentially movable stator windings allow a motor-generator to simultaneously sense and switch from a synchronous motor position to a synchronous generator position. This mechanism replaces the conventional separate sensing and switching of motor-generator functions. Automatic rotational repositioning of the stator maintains constant voltage and prevents the generation of transient voltages or harmonics. The stator flux leads the rotor magnetic flux slightly in an import power or motor position, creating a torque on the rotor and a counter torque on the stator reacted by the fixed casing of the apparatus. As the stator field weakens due to a failure of the normal power supply, the counter torque also weakens and the stator windings are biased to begin to turn with the rotor until the rotor and stator fields are in step, i.e., when virtually no current is generated or consumed or until a full export power or generator position is reached.

  • Patent number: 5428310
    Abstract: A signal-delaying capacitive circuit applied to a node in a microcircuit device is immunized against the variation of the supply voltage by a metal-oxide semiconductor connected in series between the node and the signal-delaying capacitive circuit. The gate of tile semiconductor is biased with a voltage signal proportional to the supply voltage, whereby the resistance of the semiconductor is increased as the supply voltage decreases; thus, isolating the capacitive circuit from the node and reducing the delay.

  • Patent number: 5426358
    Abstract: A rechargeable power pack is shaped and dimensioned to be inserted in the battery compartment of an electrical device. The top of the power pack is exactly symmetrical with the battery compartment cover which it replaces. The power pack houses rechargeable power cells, and has a peripheral wall spaced apart from the sides of the battery compartment mounting the battery contact terminal. Flexible prongs project from the peripheral walls to provide a wiping contact with either a spiral spring negative terminal or a stationary positive terminal of the compartment. A top mounted connector allows recharging of the power pack even while in use on the electrical device. Baffles mounted astride each flexible prong avert damage to the prong during insertion of the power pack into the battery compartment.

  • Patent number: 5425691
    Abstract: An aerobic exercise platform comprises a rigid base having a smooth and slick surface for practicing sliding exercises. Elastic or rigid holding elements are securable to a series of anchoring points located about the periphery of the base. An alternate embodiment of the invention combines a sliding exerciser with a stepping exercise stool. The stool is constituted by the two symmetrical halves of an enclosure housing a web wound around a drum. When the two halves of the enclosure are spread apart the web is deployed. The slick upper side of the web acts as a sliding surface. Alternatively, the web may be a completely separate sheet, stored in the enclosure or attached between the spread apart halves for sliding exercises. Additional features such as extensions for raising the height of the stool and bumpers for protecting the user's feet and providing an angled sliding surface may be stored within the enclosure. The angled sliding surfaces and stabilizing poles provide ski-type exercise capability.

  • Patent number: 5424672
    Abstract: In a microcircuit device such as a memory chip, where a bank of fuse-controlled latch pulse routing-circuits are used to program redundant circuits or other programming options with every memory cycle or multiple thereof, the amount of current drawn by every fuse-control circuit is reduced by controlling each bank of circuits with a bank-enabling, fuse-programmed circuit between the latch pulse source and the bank of fuse-controlled programming circuits, and by adding a second fuse into each programming circuit; whereby, the bank of programing circuits can be enabled by alternately blowing one of two fuses in the bank-enabling circuit, and each programming logic can set by alternately blowing one of its pair of fuses thus cutting off any current path through the programming circuit regardless of the programming state of the circuit.

  • Patent number: 5413751
    Abstract: High density heatsinks for microcircuit packages are formed by first mold-pressing a composite powder of free-flowing spray-dried particles of copper and at least one other denser material such as tungsten and/or molybdenum, the proportions of which are adjusted to match the thermal expansion characteristics of the microcircuit material. The pressed compacts are then heated in a sintering furnace at 1,200.degree. C. to 1,350.degree. C. in order to effect an homogeneous distribution of the melting copper throughout the structure. The process results in a readily usable component having good thermal conductivity and matched thermal expansion that requires no further machining.

  • Patent number: 5410330
    Abstract: A scroll displaying mechanism suitable for use in moving advertising displays, chart recorders and tape readers uses a pair of D.C. motors wired to operate under slightly different speed-controlling voltages in order to maintain the displayed part of the scroll between two rollers taut. A simple belt and pulley drive mechanism for each roller assures quiet and vibration-free operation. The viewing time between frame-advance and the scroll direction reversal are controlled by detection of different length markers positioned along one edge of the scroll.
