摘要： A protected electrical power system may comprise a feeder between a power source and an electrical load. A first current transformer may be positioned on the feeder in a first location. The first current transformer may have a shunt resistor electrically connected across its winding. A second current transformer may be positioned at a second location on the feeder. A control unit may be interposed between the first and second current transformers and may be interconnected with the first and second current transformers on current-monitoring loops independent from the feeder. The control unit may be responsive to a predetermined differential in feeder (DF) current between the first and second current transformers to disconnect the power source from the electrical load. The control unit may have a compensation network for reducing DF error resulting from presence of the shunt resistor in the first current transformer.

摘要： A variable frequency generator regulation control circuit and method for controlling open loop gain under changing generator speed conditions employing a high frequency pulse-width modulated signal with a duty cycle that is controlled such that variations in rectified PMG voltage and generator gain over the generator speed range can be compensated for. This signal is modulated by a low frequency pulse-width modulated signal provided by the generator regulator, using a logic gate to produce a combined signal representing an average voltage signal applied to a generator field winding as the generator speed fluctuates.

摘要： A control scheme for a wound rotor synchronous generator whereby feedback signals corresponding to the exciter field current and the generator output voltage potential combine together to control the generator output voltage in such a way that at lower generator speeds and lower load requirements, exciter field current saturation is eliminated by reducing generator output voltage. The generator control scheme includes a circuit for sensing exciter field current in logic cooperation with a circuit for sensing generator voltage. Both sensing circuits regulate the current applied to the exciter field which corresponds to the rectified current applied to the field windings of the power generator. During steady state operations the generator output voltage is regulated using the generator output voltage as a feedback signal. At lower speeds and reduced loads and as the exciter field current approaches the saturation point, the generator output voltage is regulated using the exciter field current as a feedback signal.

摘要： An improved device for distributing tickets or coupons is disclosed that includes a plurality of ticket chutes each having a ticket guide assembly for guiding tickets through the chute and an exit slot and biasing tickets against a drive wheel which engages the tickets. The drive wheel is powered by a motor which uses a drive belt to power a screw gear which in turn rotates and axle on which the drive wheel is attached. The motor is activated by a controller in response to an input signal and the controller may also received input from an optical sensor in the chute for the detection of the tickets and the movement of the motor.
