Stepper motor circuits

Claim 1

A CIRCUIT MEANS FOR ENERGIZING MAGNETIC FIELD PRODUCING MEANS COMPRISING, IN COMBINATION: A SOURCE OF ELECTRICAL ENERGY; A PLURALITY OF SWITCH MEANS FOR CONNECTING SAID SOURCE TO SAID MAGNETIC FIELD PRODUCING MEANS TO ESTABLISH A MAGNETIC FIELD IN A GIVEN DIRECTION DEPENDENT UPON WHICH OF SAID PLURALITY OF SWITCH MEANS ARE CLOSED AND WHICH ARE OPEN; A CLOCKWISE INPUT TERMINAL; A COUNTERCLOCKWISE INPUT TERMINAL; A FIRST CONTROL MEANS FOR CLOSING AND OPENING SAID PLURALITY OF SWITCH MEANS IN A GIVEN SEQUENTIAL ORDER IN RESPONSE TO RECEPTION OF ELECTRICAL PULSES ON SAID CLOCKWISE INPUT TERMINAL, SAID FIRST CONTROL MEANS COMPRISING A PLURALITY OF CLOCKWISE LOGIC CIRCUITS RESPONSIVE TO PULSES ON SAID CLOCKWISE INPUT TERMINAL AND CONNECTED TO BE RESPONSIVE TO THE STATE OF SAID SWITCH MEANS, EACH CLOCKWISE LOGIC CIRCUIT BEING CONNECTED TO ENERGIZE SAID SWITCH MEANS FROM ITS PREVIOUS STATE TO THE STATE FOLLOWING SAID PREVIOUS STATE IN SAID GIVEN SEQUENTIAL ORDER; AND SECOND CONTROL MEANS FOR CLOSING AND OPENING SAID PLURALITY OF SWITCH MEANS IN THE OPPOSITE OF SAID SEQUENTIAL ORDER IN RESPONSE TO RECEPTION OF ELECTRICAL PULSES ON SAID COUNTERCLOCKWISES INPUT TERMINAL, SAID SECOND CONTROL MEANS COMPRISING A PLURALITY OF COUNTERCLOCKWISE LOGIC CIRCUITS RESPONSIVE TO PULSES ON SAID COUNTERCLOCKWISE INPUT TERMINAL AND CONNECTED TO BE RESPONSIVE TO THE STATE OF SAID SWITCH MEANS, EACH COUNTERCLOCKWISE LOGIC CIRCUIT BEING CONNECTED TO ENERGIZE SAID SWITCH MEANS FROM ITS PREVIOUS STATE TO THE STATE PRECEDING SAID PREVIOUS STATE IN SAID GIVEN SEQUENTIAL ORDER.
