An apparatus for use with a refrigeration system including a compressor for compressing a working fluid evaporated in an evaporator and condensed in a condenser. A control circuit initiates operation of a refrigeration cycle and initiates a defrost cycle in response to a defrost enable signal. The apparatus drives an air moving assembly moving air over the evaporator. A motor including a rotatable assembly is in driving relation to the air moving assembly. An energizing circuit selectively energ...

A motor system having a stationary assembly including a winding and a rotatable assembly in magnetic coupling relation to the stationary assembly. A power supply link having upper and lower rails supplied by a power supply provides power to the motor winding. The power supply link has power switches responsive to a motor control signal for selectively connecting the rails to the winding to energize the winding with a motor current whereby an electromagnetic field is produced for rotating the rot...

Methods and apparatus for automated testing of centrifugal start mechanisms for electric motors are described. In one embodiment, the system includes a stepper motor and an adapter secured to the stepper motor shaft. The adapter includes a shaft sized to have a diameter about equal to the diameter of a rotor shaft which carries the start mechanisms to be tested. The system also includes a fiber optic sensor having an optical signal transmitter and an optical signal receiver. The transmitter and ...

A vehicular headlight having a low height-to-width ratio includes a plurality of collimating lenses. The collimated light output from certain ones of the lenses is redirected into the forward direction by separate sets of reflectors associated with the respective lenses. Means are provided to impose a desired light pattern on the forward-directed light outputs.

An ice-cube making device for use in a refrigerated cabinet is provided. The ice-cube making device is attachable to a freezer liner and thus makes efficient use of the space in the freezer cavity. The ice-cube making device includes a mechanism for extracting ice by applying a twisting torque to one or more ice-cube trays therein. The ice-cube making device may also include mechanisms for refilling the ice trays with water and for providing a user-friendly installation. Aspects of the present i...

A method, adhesive sheet, and kit are provided to enable lifting and shaping to a female human breast. The kit may include a mushroom-shaped adhesive sheet comprising a curvilinear section and a rectangular section. The kit may further include a set of instructions for applying the adhesive sheet to a female human breast in conjunction with manipulations performed on the breast to provide lifting and shaping to the breast.

A single phase permanent magnet motor includes a rotor, a stator, and a quadrature axis winding positioned out-of-phase from a main winding of the stator for generating an output signal representative of rotor angular position. An integrator can be coupled to the quadrature axis winding for phase retarding the output signal, and a comparator can be coupled to the integrator for detecting zero crossings of the phase retarded output signal to provide a commutation signal. The quadrature axis windi...

A drive package for a dynamoelectric machine mounts a printed wire board in cantilever fashion from a wall of a drive package housing. Potting material in the housing provides mechanical support for the printed wire board away from the heat sink. Heat generating components on the first printed wire board have tubes of electrically insulating, thermally conductive material inserted over them and are clamped against the heat sink. The heat sink is mounted directly to the housing and is electricall...

Methods and apparatus for coupling a conduit to an electric motor by way of a moisture resistant two-piece connector, are described. The two-piece connector includes, in one embodiment, a boss sized to be at least partially located in an end portion of a plastic, non-metallic conduit and a protective cover that substantially covers the motor shell notch at least between the boss and the motor shell notch edges. More specifically, in the one embodiment, the two-piece connector includes first and ...
