  • Patent number: 6846257
    Abstract: A clutch mechanism is disclosed for use with a hybrid electric vehicle wherein the electric motor-generator and engine are arranged in a series configuration. The clutch mechanism is positioned between and in communication with the electric motor-generator and engine to allow for either direct drive or a predetermined gear ratio between the electric motor-generator and engine. The electric motor-generator is preferably an integrated electric motor and generator. The engine is preferably a combustion engine.
    Type: Grant

  • Patent number: 6834750
    Abstract: A clutch mechanism is disclosed for use with a hybrid electric vehicle wherein the electric motor/generator and engine are arranged in a series configuration. The clutch mechanism is positioned between and in communication with the electric motor/generator and engine to allow the electric motor/generator to either: 1) provide sole motive power to the vehicle; 2) start the engine; 3) charge the vehicle's battery; 4) provide a power boost; or 5) provide regenerative braking. The clutch mechanism includes an outer race, an inner race, a roller set positioned between the inner and outer races, and a roller cage positioned adjacent the roller set to contain the roller set. The electric motor is preferably an integrated electric motor and generator. The engine is preferably a combustion engine.

  • Patent number: 6679367
    Abstract: An over-running clutch assembly for an automotive transmission comprises an outer race having a cylindrical inner surface and an inner race engaged with a drop shaft of the transmission and having a cammed outer surface coaxial with the cylindrical inner surface and defining a gap therebetween and a roller clutch disposed within the gap; a biasing element to bias the roller clutch to a disengaged position; and an actuator to selectively overcome the biasing element to engage the roller clutch and lock the outer race and inner race and prevent relative rotation between the outer race and inner race, thereby preventing rotation of the drop shaft and movement of the automobile.

  • Patent number: 5053927
    Abstract: A pocket within the molded casing of a solid electrolyte capacitor is of greater volume than a fuze passing through the pocket, thereby ensuring that the fuze will not reestablish its conductive path after being blown. The pocket is established between layers of polyester tape that insulate the cathode of the capacitor from its leadframe and protect the fuze from the molding material.

  • Patent number: 4402434
    Abstract: An automatic closure device for containers being openable by pressure on the container and closable when such pressure is released. A cap member having a discharge orifice adapted to be closed by a plug member on a hollow stem is provided. The hollow stem has a discharge port. A diaphragm is positioned on said stem extending out to said cap, and a seal member having an aperture defined therein for receipt of said stem is positioned within said cap forming a pressure chamber between it and the diaphragm. Above the diaphragm which is resilient and movable downwardly by pressure is a discharge chamber. A lock is provided to also lock the plug in an open or in a closed mode.

  • Patent number: 3961941
    Abstract: A process for producing metallic lead and silver from materials such as ores and concentrates containing the corresponding sulfides and particularly a mixture of minerals such as galena and tetrahedrite in which process the minerals are initially roasted under neutral conditions which include a non-oxidizing or even slightly reducing atmosphere at an elevated temperature for a time equivalent to about 1.5 hours at about 550.degree.-600.degree.C. to produce a roasted mineral product in which the roasting causes certain unidentified changes but with the resulting roasted product being more easily leachable so that the process of removing the silver and lead can be greatly simplified.
