Abstract: An air turbine starter for starting an engine, comprising a housing defining an inlet, an outlet, and a flow path extending between the inlet and the outlet for communicating a flow of gas there through. A turbine member is journaled within the housing and disposed within the flow path for rotatably extracting mechanical power from the flow of gas and a gear train is drivingly coupled with the turbine member. A drive shaft is operably coupled with the gear train, and a decoupler is selectively coupled to the drive shaft for decoupling the air turbine starter from the engine.

Abstract: An air turbine starter that includes a turbine member for rotatably extracting mechanical power from a flow of fluid, where the turbine member is coupled to a drive shaft to provide a rotational output. The air turbine starter further includes a foil-air bearing assembly and a thrust bearing that rotatably support the drive shaft.

Abstract: An air starter for starting a turbine engine that includes a housing, a turbine member, a drive shaft, and at least one bearing assembly. The housing can define an interior where the turbine couples to the drive shaft that is rotatably supported by the least one bearing assembly. A lubricant passageway can provide lubrication to the at least one bearing assembly.

Abstract: A method and decoupler for disengaging an output shaft from an engine in a back drive event with a backdrive decoupler. The backdrive decoupler includes a an output shaft, drive shaft, and a retention mechanism selectively coupling the output shaft to the drive shaft. In a backdrive event, the decoupler decouples the output shaft from the drive shaft.

Abstract: A heat pump water heater and systems and methods for its control. The systems are configured to heat water within a water storage tank of a heat pump water heater wherein a controller within the system is operatively connected to a plurality of heat sources including at least one electric heating element and a heat pump and sensors in order to selectively energize one of the plurality of heat sources. The controller is configure to process data representative of the temperature of water within the tank near the top of the water storage tank, and rate of water flowing out of the water storage tank, in order to automatically selectively energize the heat sources. The selection of heat sources by the controller is determined by a mode of operation selected by the user and the data processed by the controller in view of the selected mode of operation.

Abstract: A water heater is provided that includes a centering ring or thermal barrier that facilitates centering or alignment of the water tank while also diminishing heat loss through the bottom of the water heater. Features are provided with the bottom of the water heater and centering ring that can also improve the stability of the water heater when placed in a vertically upright position.

Abstract: A duct adapter system directs air flow relative to a hybrid water heater. The duct adapter system includes a collar adapted to surround a vent of a hybrid water shroud. The collar couples to standard duct pipe to extend ductwork to a heat pump portion of the hybrid water heater. A boost fan may be included in the system for boosting air flow to or from a remote location. The duct adapter system is adapted to deliver a warm air supply to the heat pump from the remote location, or deliver the cool discharge air from the heat pump water heater to a remote location.

Abstract: A method and modified clothes washer provides for an overnight dry cycle. A standard washer is modified to draw air from external to the housing, direct the air into the tumbling drum, and remove the air with a blower to exhaust from the housing during an extended drying period overnight. By selecting this option, the consumer need not move the clothes from the washer to the dryer.
