Abstract: A remote control circuit breaker system in which an electronic logic unit is built into a main electromagnetically operated circuit breaker to act as the controlling interface between the latter and a remotely located pilot control-circuit breaker unit. In addition to directing main circuit breaker operation to provide closing and opening of the same in correspondence with the operation of the pilot unit, the logic unit responds on overload trip open of the main circuit breaker to subject the pilot unit to a controlled value of simulated overload current as will cause the latter to trip open and afford indication of the occurrence of overload tripping in the main circuit breaker. The logic unit also affords coordination of a plurality of such circuit breakers in a multiphase A.C. system so that all will be responsive to the operation of a single remote pilot unit, and will also trip open following overload response of any thereof. Further the logic unit automatically functions in the event of a fault occurring in the pilot unit or the line connecting it with the main breaker to limit the value of fault to a non-destructive value, and prevents repeated circuit breaker cycling in the event the pilot breaker fails to open. The main circuit breaker uses double-break contacts and permanent magnet latching to improve its arc rupture withstandability and eliminate the necessity of continuous energization of its electromagnetic operating coils. The overload trip mechanism in the main circuit breaker uses a low friction latch, and together with ambient temperature compensation in the bimetal latch release enhances the trip point precision.

Abstract: A REMOTE CONTROL CIRCUIT BREAKER SYSTEM IN WHICH AN ELECTRONIC LOGIC UNIT IS BUILT INTO A MAIN ELECTROMAGNETICALLY OPERATED CIRCUIT BREAKER TO ACT AS THE CONTROLLING INTERFACE BETWEEN THE LATTER AND REMOTELY LOCATED PILOT CONTROL-CIRCUIT BREAKER UNIT. IN ADDITION TO DIRECTING MAIN CIRCUIT BREAKER OPERATION TO PROVIDE CLOSING AND OPENING OF THE SAME IN CORRESPONDENCE WITH THE OPERATION OF THE PILOT UNIT, THE LOGIC UNIT RESPONDS ON OVERLOAD TRIP OPEN OF THE MAIN CIRCUIT BREAKER TO SUBJECT THE PILOT UNIT TO A CONTROLLED VALUE OF SIMULATED OVERLOAD CURRENT AS WILL CAUSE THE LATTER TO TRIP OPEN AND AFFORD INDICATION OF THE OCCURENCE OF OVERLOAD TRIPPING IN THE MAIN CIRCUIT BREAKER. THE LOGIC UNIT ALSO AFFORDS COORDINATION OF A PLURALITY OF SUCH CIRCUIT BREAKERS IN A MULTIPHASE A.C SYSTEM SO THAT ALL WILL BE RESPONSIVE TO THE OPERATION OF A SINGLE REMOTE PILOT UNIT, AND WILL ALSO TRIP OPEN FOLLOWING OVERLOAD RESPONSE OF ANY THEREOF. FURTHER THE LOGIC UNIT AUTOMATICALLY FUNCTIONS IN THE EVENT OF A FAULT OCCURRING IN THE PILOT UNIT OR THE LINE CONNECTING IT WITH THE MAIN BREAKER TO LIMIT THE VALUE OF FAULT TO A NON-DESTRUCTIVE VALUE, AND PREVENT REPEATED CIRCUIT BREAKER CYCLING IN THE EVENT THE PILOT BREAKER FAILS TO OPEN. THE MAIN CIRCUIT BREAKER USES DOUBLE-BREAK CONTACTS AND PERMANENT MAGNET LATCHING TO IMPROVE ITS ARC RUPTURE WITHSTABILITY AND ELIMINATE THE NECESSITY OF CONTINUOUS ENERGIZATION OF ITS ELECTROMAGNETIC OPERATING COILS. THE OVERLOAD TRIP MECHANISM IN THE MAIN CIRCUIT BREAKER USES A LOW FRICTION LATCH, AND TOGETHER WITH AMBIENT TEMPERATURE COMPENSATION IN THE BIMETAL LATCH RELEASE ENCHANCES THE TRIP POINT PRECISION.

Abstract: A solid state switching circuit and power controller for permanent magnet and shunt field winding motors used in portable power tools and the like. The power controller employs a bidirectional thyristor triode and trigger diode for varying the current supplied to the motor armature, and a full-wave rectifier bridge to establish unidirectional current flow through the motor armature on opposite half cycles of the AC power supply. A resistor across the AC terminals of the rectifier bridge enhances control action under light loads.

Abstract: A full-wave adjustable motor speed control system with feedback for automatic regulation of the speed of an AC motor such as a series or universal motor. A bidirectional thyristor triode in series with the motor armature winding is controlled by a firing circuit operated by a ramp and pedestal voltage. The ramp may be set at a fixed value whereas the pedestal is adjusted for desired speed and regulated by a feedback signal. This feedback signal is developed in an amplifying feedback circuit that is adjusted to eliminate unwanted characteristics and to provide a true speed signal proportional to motor counter EMF.
