  • Patent number: 4761911
    Abstract: An animal snare includes a built-in force urging the snare loop toward a constricted, relatively small triggered position from a larger setting position. When the snare is released from the triggered position by an animal, the built-in force accelerates constriction of the loop, preventing animal escapes that might otherwise occur. The snare includes a flexible cable having opposed anchor and loop ends, with the loop end slidably engaged by a catch to an intermediate portion of the cable to form the constrictable ensnaring loop and for releasably, frictionally restraining the loop end relative to the intermediate portion when the snare is in its setting position. The built-in force is introduced during manufacture of the snare by giving a permanent set to the portion of the snare cable proximate its loop end.

    Abstract: In a gas turbine propulsion unit with means for branching off compressor air for purposes of cooling hot parts of the turbine, the cooling air is conducted to the hot parts to be cooled along a detour by way of structural parts of high heat capacity and large surface area. It is achieved therewith that with a jump-like change of the cooling air temperature as, for example, during an acceleration operation, the cooling air gives off a portion of its heat content along the detour to the structural parts so that the thermal time behavior of the cooling air is slowed down.

  • Patent number: 4761948
    Abstract: Systems capable of supplying either all gaseous fuel, all liquid fuel, or a mixture of the two, at a preselected ratio have been successfully employed in gas turbine engines. The mixing of such fuels has taken place in the combustion chamber and has caused the nozzle design and system controls to complicate the structure and increase costs. The subject system for burning gaseous fuels having a range of calorific values has overcome these problems by providing a simple inexpensive system. The system uses a starting step where only high calorific value gaseous fuel is injected through a first fuel supply passage of an injector and operates the engine to a preestablished engine operating parameter.

  • Patent number: 4761950
    Abstract: In a double air-fuel sensor system including two air-fuel ratio sensors upstream and downstream of a catalyst converter provided in an exhaust gas passage, an actual air-fuel ratio is adjusted in accordance with the outputs of the upstream-side and downstream-side air-fuel ratio sensors. A center value of an air-fuel ratio correction amount or an air-fuel ratio feedback control parameter calculated based upon the output of the downstream-side air-fuel ratio sensor is calculated by a learning control, and an air-fuel ratio feedback control is initiated by using the center value when the engine enters into an air-fuel ratio feedback control state.

  • Patent number: 4761953
    Abstract: The invention contemplates hydraulic-lift mechanism which employs a power integrator in the connection between a charged hydraulic accumulator and the actuator for a vertically positionable load; the power integrator, additionally, has a prime-mover connection, and the pressurized charge of the accumulator is advisedly set to fully accommodate a preselected level of average load upon the actuator. The hydraulic circuit importantly includes check valves, with a pilot-operated check valve interposed between the power integrator and the accumulator and another pilot-operated check valve interposed between the power integrator and the load actuator. The pilot-operated check valves cooperate with other check valves to assure automatic transfer of hydraulic fluid under pressure from the accumulator to the load actuator, and vice versa, as may be determined by selected control of or via the power integrator.

  • Patent number: 4761954
    Abstract: A battery-operated electric-motor driven hydraulic-lift mechanism for a fork-lift vehicle employs a hydraulic accumulator which serves an intertia-free counterweight function, designedly to the degree that such counterweight action is a direct offset of a predetermined average-load condition, as seen by the hydraulic-lift actuator of the system. Electric-motor drive is utilized for up/down operation of the fork lift, only to the extend needed to displace hydraulic fluid into or out of the "counterweighted" actuator. In some cases, such displacement will call for expending energy to add to or substract from the counterweight action; in other cases, the necessary fluid displacement results in an energy return to the system, i.e., in restoring energy to the battery.

  • Patent number: 4761958
    Abstract: Self-excited vibrations can occur in the combustion chambers of gas turbines, which vibrations are due to modulation of the quantity of gaseous fuel or fuel/air mixture as the fuel is injected through a nozzle and into the combustion chamber. The modulation results from pressure fluctuations that occur in the plane of the nozzle. The new fuel lance simultaneously permits both de-coupling of the fuel line in order to avoid combustion chamber vibrations and the possibility of fuel quantity control. The fuel lance comprises an adjustable throttle body that is provided with fuel passage openings and a plunger, the penetration depth of which plunger relative to that of the throttle body is a measure of the fuel quantity flowing therethrough.
