Abstract: A wind turbine power generating system, including a wind turbine connected to a speed-increasing gearbox having an output shaft. An electrical generator having an input shaft is also provided. A coupling interconnects the input and output shafts. The coupling includes a high torsional wind-up and/or displacement ability in parallel with a high frictional slip ability, such that during normal operation there is little or no frictional slippage and during a transient torque reversal the loads in the turbine drive system are decreased, thus decreasing the impact loads on the gearbox bearings.

Abstract: An asymmetric torque limiting coupling system for use on wind turbines, in which a forward torque limiting clutch and a reverse torque limiting clutch are provided in paired relation, with the reverse torque limiting clutch having a characteristic slip torque that is significantly less than that of the forward torque limiting clutch. In a specific embodiment disclosed, an asymmetric torque limiter interconnects a wind turbine with a generator shaft. The coupling includes an input housing and an output hub, with an overrunning mechanism interposed between the two. A first torque limiting mechanism is provided in series interconnection with the overrunning mechanism between the input housing and hub, while a second torque limiting mechanism is provided in parallel interconnection with the overrunning mechanism between the input housing and output hub.

Abstract: A wind turbine power generating system includes a wind turbine connected to a speed increasing gearbox having an output shaft. An electrical generator having an input shaft is also provided. An asymmetrical coupling interconnects the input and output shafts. The coupling includes a first torque limiting clutch in series connection with a one-way clutch between the input and output shafts. A second torque limiting clutch is provided in parallel connection with the one-way clutch between the input and output shafts. The first and second torque limiting clutches have different characteristic slip torques. The interconnection of the clutches, and the implementation of the one-way clutch, provides for effective operation of the first and second torque limiting clutches in opposite rotational directions of the input and output shafts.

Abstract: A compact disc spring torque limiting clutch has an input hub and an output hub having a friction pack that is removable from the input hub as an entire unit to facilitate servicing and repair. The force actuator of the torque limiting clutch is a Belleville spring or machined disc spring that is operatively interposed between the input hub and the friction pack. The deflection of the Belleville spring during the useful life of the friction pack is within the flat portion of the force vs. deflection curve and establishes a characteristic breakaway torque for the torque limiting clutch. The use of a Belleville spring significantly reduces the axial dimension of the torque limiting clutch, adapting it for use in applications where space is at a premium.

Abstract: An oil cooled electric drive module for hybrid vehicles includes an AC motor assembly having a shaft parallel to an output shaft, with the shafts being interconnected by a set of helical reduction gears. The motor shaft is provided with a rotary union for cooling oil that passes first axially and then radially through the shaft to an outer circumferential surface thereof beneath the core of a rotor attached thereto. The cooling oil passes beneath the rotor to the outer ends thereof, where annular deflectors disburse the oil to provide a coanda effect over the shorting rings of the rotor, onto the stator windings, and thence onto the motor housing for return to a cooling sump, which may include hydraulic and electric pumps for further desired cooling circulation. The invention also includes solenoid valves for shifting a splined collar between positions of interconnection and disconnection between the motor shaft and output shaft.

Abstract: A photovoltaic awning assembly includes a sheet of material carrying photovoltaic strips thereon. A rotatable roll receives the sheet of material and has a contoured drum at opposite ends thereof for deploying and retrieving the sheet of material through the use of a cable connected to a boom at an opposite end of the sheet. A pair of support tubes extend along opposite sides of the sheet of material, and support legs serve to position the sheet. In one embodiment of the invention, one of the support legs is out of plane with the others, introducing a saddle surface in the sheet of material to provide it with stability to resist wind. The roll for retrieving and maintaining the material is constructed of a non-metallic material such as corrugated fiberglass sheet, rolled about take-up drums at opposite ends thereof, and having reinforcing flanged disks in the interior thereof. The corrugations provide conduits for the passage of electrical conductors to an externally maintained control box.

Abstract: A deployable and retractable photovoltaic awning assembly is formed from a flexible sheet of photovoltaic devices attached to a rotatable roll at one end and a boom at the other. A pair of side support tubes are provided with tracks that receive slides maintained on opposite ends of the boom. At least one of the slides is axially movable with respect to the boom, ensuring engagement of the slides in the tracks as the boom is moved away from and toward the roll during deployment and retraction of the flexible sheet. In this regard, the slides are mounted on pins through articulated joints of the spherical/universal type. The sheet of flexible voltaic devices is preferably transmissive as to light wave lengths in the range required for vegetation photosynthesis, and absorbert for all other ranges, allowing the awning to be deployed over vegetated areas, without interference with the photosynthesis process.

Closed systems are disclosed in which one or more awning fabrics can be extended through a single drive system. In particular embodiments, the shade structures cover large surface areas and include solar cells for the generation of photovoltaic power.

Abstract: A compressed air pumped hydro energy storage and distribution system includes a first reservoir of water and a second reservoir of air and water. An air pressure source, connected to the second reservoir, develops a pressure head in the second reservoir. A pump/turbine-motor/generator, received by the first reservoir, is connected to a regional energy grid. During peak demand periods, the pressure head forces water through the pump/turbine-motor/generator to generate power, delivered to the grid. During low demand periods, the pump/turbine-motor/generator pumps water back to the second reservoir, regenerating the pressure head. A third air reservoir interconnected with the second reservoir and a gas turbine generator can be used to generate power during peak demand periods. The reservoirs can be tunnels or abandoned mines, reinforced and sealed by pressure grouting and/or an internal liner, maintained well beneath the earth's surface and intersecting the path of the grid.

The flute has an inner surface that has at least one magnet to secure a golf club shaft within the flute. The flute is any structure that accepts a golf club shaft. The golf club support is any structure that is adapted to hold a golf club head and that prevents a golf club head from chaffing and scratching against another golf club or other items found in the golf club bag.

Abstract: A compact dry power takeoff clutch unit is adapted for interconnection with a flywheel of an engine. A housing is adapted for attachment to the engine and has a plurality of interleaved friction and separator disks maintained therein. A drive ring is connected to the friction disks and to the flywheel for driving the friction disks by the engine. An output shaft is interconnected with the separator disks. A pair of anti-friction bearings are received by the housing and provide the sole support for the output shaft. A pressure plate is configured to be nestingly received by a cup-shaped flywheel in order to maintain certain standardized dimensional constraints. Actuation of the clutch is achieved by a rotary union interposed between the pair of support bearings. A quiescent position for the separator disks is achieved by the mounting of the separator disks between the head and spring of shoulder bolts secured to an output hub mounted upon the output shaft.
