Electric motor control circuit

Claim 1

A CONTROL CIRCUIT RESPONSIVE TO INPUT PULSES ON TWO SEPARATE INPUT CHANNELS FOR CONTROLLING MOVEMENT OF A MOTOR HAVING A FIRST WINDING WHICH IS ENERGIZED OF ONE POLARITY OR THE OTHER AND A SECOND WINDING WHICH IS ENERGIZED OF ONE POLARITY OR THE OTHER WITH EACH INPUT PULSE ALTERNATELY SHIFTING THE POLARITY OF THE FIRST AND SECOND WINDINGS COMPRISING A FIRST TWO-STATE BISTABLE FLIP-FLOP MEANS HAVING AN OUTPUT CONNECTED TO THE FIRST WINDING FOR ENERGIZING THE FIRST WINDING OF ONE POLARITY FOR ONE STATE AND THE OTHER POLARITY FOR THE OTHER STATE, A SECOND FLIP-FLOP MEANS HAVING AN OUTPUT CONNECTED TO THE SECOND WINDING FOR ENERGIZING THE SECOND WINDING OF ONE POLARITY FOR ONE STATE AND THE OTHER POLARITY FOR THE OTHER STATE, EACH OF SAID FLIP-FLOP MEANS INCLUDING TWO TRANSISTORS WITH EACH HAVING A TRIGGER POINT AND A SENSE POINT WITH ONE TRIGGER POINT AT ONE STATE BEING AT A HIGHER POTENTIAL THAN THE OTHER AND WITH THE OTHER TRIGGER POINT BEING AT A HIGHER POTENTIAL THAN THE ONE AT THE OTHER STATE AND WITH THE SENSE POINT OF THE TRANSISTOR HAVING THE HIGHER POTENTIAL TRIGGER POINT BEING AT A LOWER POTENTIAL THAN THE SENSE POINT OF THE TRANSISTOR HAVING THE LOWER POTENTIAL TRIGGER POINT, EIGHT DIODES WITH EACH HAVING AN ANODE AND CATHODE ENDS, MEANS CONNECTING THE SIMILAR ENDS OF THE DIODES IN PARALLEL TO FORM FOUR PAIRS OF DIODES, MEANS CONNECTING THE DIODES TO THE TRIGGER POINTS, ONE PAIR TO EACH TRIGGER POINT, MEANS CONNECTING ONE OF EACH PAIR TO EACH INPUT CHANNEL WITH THE DIODES BEING CONNECTED TO BE CONDUCTIVE IN THE SAME DIRECTION AND MEANS CONNECTING THE SENSE POINTS TO THE DIODES WITH EACH SENSE POINT BEING CONNECTED TO TWO DIODES WITH THE TWO DIODES BEING ONE OF TWO PAIRS OF DIODES, TO PLACE A REVERSE POTENTIAL ON SAID DIODES, ONLY TWO OF SAID DIODES CONNECTED TO ONE INPUT CHANNEL HAVING A HIGHER REVERSE POTENTIAL THAN THE OTHER TWO AND ONLY TWO OF SAID DIODES CONNECTED TO THE OTHER INPUT CHANNEL HAVING A HIGHER REVERSE POTENTIAL THAN THE OTHER TWO.
