Abstract: A power control circuit for induction motors wherein a servo loop is used to control power input by controlling the minimal power consumption of motor operation. The minimum power consumption is measured by sensing current or power and operating the servo loop at or near a minimally sensed power consumption level. The negative derivative of power consumption vs voltage curve, dP/dV, is sensed and a minimal value is used in a servo loop's error summing point wherein compensating slightly drives the power consumption point past the minimal power consumption point to regulate minimal power consumption by a smooth, minimal cycle. Maximum energy savings is thus attained with a smooth, stepless regulating method placing no mechanical stress on the motor-and-load combination. An indicator of power savings and normal operation is inherent in this type of control system which provides for a device for both indicating the level of savings and alerting of system faults.

Abstract: An ice maker is disclosed for freezing ice pieces and delivering the ice pieces to a receptacle under a chute. The ice machine is made up of an ice mold with an opening in its bottom which receives and ice extractor with an open bottom and upwardly and outwardly extending sides. An evaporator plate is supported below the opening in the ice mold bottom and a water supply is provided to maintain the water in the mold at a predetermined level. A thermo electro unit is disposed below the evaporator. Classical freon refrigeration can also be used. Thus when water is frozen to ice in the extractor, the refrigeration, or thermo-electric means melts the ice loose from the evaporator, in some models, and also from the ice extractor. The ice extractor, which is attached to a motor by means of an arm, swings to an inverted position over an ice chute from which the ice falls, is in some models aided by ambient heat, into a repository. The extractor then swings back into the mold for another cycle.
