Static control for step type transformer regulator

Claim 1

A CONTROL SYSTEM FOR AN ELECTRICAL MOTOR COMPRISING A SIGNAL PRODUCING DETECTOR RESPONSIVE TO A PREDETERMINED ELECTRICAL CONDITION, ELECTRICAL SOURCE FOR SAID ELECTRICAL MOTOR, CIRCUIT MEANS CONNECTING SAID MOTOR TO SAID SOURCE AND INCLUDING ELECTROMAGNETIC MEANS FOR CONTROLLING THE VOLTAGE BEING APPLIED TO SAID MOTOR FROM SAID SOURCE, SAID ELECTROMAGNETIC MEANS COMPRISING A FIRST SATURABLE REACTOR HAVING A CORE, REACTANCE WINDING, AND CONTROL WINDINGS, MEANS FOR APPLYING A BIAS CURRENT TO ONE OF SAID CONTROL WINDINGS SUCH THAT SAID REACTANCE WINDING EFFECTIVELY PREVENTS SAID SOURCE FROM SUPPLYING SAID MOTOR, MEANS FOR SUPPLYING A CURRENT FROM SAID SIGNAL PRODUCING DETECTOR TO A SECOND OF SAID CONTROL WINDINGS WITH THE AMPERE TURNS SUPPLIED BY SAID SECOND CONTROL WINDING BEING SUFFICIENT TO DRIVE SAID CORE TO SATURATION, TIME DELAY MEANS, SAID TIME DELAY MEANS COMPRISING A SECOND SATURABLE REACTOR HAVING FIRST AND SECOND INDUCTIVELY RELATED WINDING MEANS AND A SATURABLE CORE, DIRECT CURRENT BIAS MEANS CONNECTED TO DRIVE THE CORE OF SAID TIME DELAY MEANS TOWARD NEGATIVE SATURATION, MEANS FOR CONNECTING A SIGNAL FROM SAID SIGNAL PRODUCING DETECTOR TO SAID FIRST WINDING MEANS TO DRIVE THE CORE OF SAID TIME DELAY MEANS TO POSITIVE SATURATION, AN OUTPUT CIRCUIT RESPONSIVE TO CURRENT INDUCED IN SAID SECOND WINDING MEANS FOR SAID TIME DELAY MEANS DURING THE PERIOD OF CHANGE OF SATURATION OF THE CORE OF SAID TIME DELAY MEANS FOR APPLYING CURRENT TO A THIRD CONTROL WINDING ON SAID FIRST SATURABLE REACTOR, RESISTANCE MEANS IN SAID OUTPUT CIRCUIT FOR VARYING THE TIME FOR CHANGING THE SATURATION OF SAID TIMING CORE FROM NEGATIVE TO POSITIVE, THE AMPERE TURNS OF SAID THIRD CONTROL WINDING OPPOSING THE AMPERE TURNS OF SAID SECOND CONTROL WINDING OF SAID FIRST SATURABLE REACTOR SO THAT SAID BIAS CONTROL WINDING ON SAID FIRST SATURABLE REACTOR IS EFFECTIVE TO PREVENT THE SUPPLY VOLTAGE TO SAID ELECTROMAGNETIC MEANS FROM BEING EFFECTIVE TO CAUSE OPERATION OF SAID MOTOR, THE CHARACTERISTICS OF SAID TIME DELAY MEANS BEING SUCH THAT THE APPLICATION OF A SIGNAL FROM SAID SIGNAL PRODUCING DETECTOR IS EFFECTIVE DURING THE FLUX CHANGE IN THE CORE OF SAID TIME DELAY MEANS TO PROVIDE SIGNAL AMPERE TURNS TO SAID THIRD CONTROL WINDINGS TO COUNTERACT THE EFFECTIVENESS OF THE AMPERE TURNS OF SAID SECOND CONTROL WINDING UNTIL THE CORE OF SAID TIME DELAY MEANS IS DRIVEN TO POSITIVE SATURATION.
