Multiphase electrical system

Claim 1

A CONTROL CIRCUIT FOR A MOTOR HAVING N STATOR WINDINGS PRODUCING FIELDS EQUIANGULARLY SPACED FROM EACH OTHER AND A ROTOR WHICH ALIGNS ITSELF WITH SAID FIELDS, SAID CIRCUIT COMPRISING: A RING COUNTER INCLUDING N FLIP-FLOPS EACH HAVING FIRST AND SECOND STABLE STATES, EACH FLIP-FLOP HAVING FIRST AND SECOND INPUT TERMINALS AND FIRST AND SECOND OUTPUT TERMINALS, WITH SAID FIRST OUTPUT TERMINALS INDIVIDUALLY CONNECTED TO DIFFERENT ONES OF SAID WINDINGS, AND WITH ALL SAID FIRST INPUT TERMINALS COMMONLY CONNECTED TO A SIGNAL INPUT SELECTOR MEANS, AND WITH SAID SECOND OUTPUT TERMINALS CONNECTED RESPECTIVELY TO THE SECOND INPUT TERMINALS OF THE NEXT ADJACENT FLIP-FLOP IN A MANNER SUCH THAT ONLY ONE FLIP-FLOP AT A TIME WILL ASSUME THE FIRST STABLE STATE OF OPERATION IN WHICH IT ENERGIZES THE CORRESPONDING STATOR WINDING; AND FIRST AND SECOND INPUT SIGNAL SOURCES COUPLED TO SAID INPUT SELECTOR MEANS AND ALTERNATIVELY SELECTABLE THEREBY FOR APPLYING FLIP-FLOP SELECTOR MEANS AND ALTERNATIVELY SELECTABLE THEREBY FOR APPLYING FLIP-FLOP ACTUATING SIGNALS TO SAID COMMONLY CONNECTED FIRST INPUT TERMINALS; SAID FIRST SOURCE COMPRISING MEANS TO PROVIDE A TRAIN OF SINGLE PULSES FOR SUCCESSIVELY SWITCHING SAID FLIPFLOPS WHEREBY SAID MOTOR IS DRIVEN IN A FIRST ANGULAR DIRECTION, AND SAID SECOND SOURCE COMPRISING MEANS TO PROVIDE A TRAIN OF GROUPS OF RELATIVELY CLOSELY SPACED PULSES, WITH EACH GROUP INCLUDING A NUMBER OF PULSES EQUAL TO ONE LESS THAN THE NUMBER OF SAID FLIP-FLOPS FOR SUCCESSIVELY SWITCHING ALL BUT ONE OF SAID FLIP-FLOPS IN A MANNER SUCH THAT SAID MOTOR IS DRIVEN IN A SECOND ANGULAR DIRECTION AT A ROTATIONAL SPEED CORRESPONDING TO THE REPETITION RATE OF SAID GROUPS OF PULSES.
