Claim 1

A SHIFT REGISTER COMPRISING A PLURALITY OF ELEMENTAL CIRCUITS CONNECTED IN CASCADE, EACH ELEMENTAL CIRCUIT INCLUDING A TRANSISTOR HAVING A BASE, EMITTER, AND COLLECTOR, A FIRST PULSE INPUT CIRCUIT CONNECTED TO THE BASE OF THE TRANSISTOR FOR INJECTING MINORITY CARRIERS IN THE FORM OF A DISCRETE PULSE TO ESTABLISH A CARRIER STORAGE CONDITION THEREIN, A SECOND PULSE INPUT CIRCUIT CONNECTED IN THE BASEEMITTER CIRCUIT OF THE TRANSISTOR FOR EXTRACTING MINORITY CARRIERS FROM THE BASE TO TERMINATE THE CARRIER STORAGE CONDITION, AN OUTPUT CIRCUIT CONNECTED IN THE COLLECTOR-EMITTER CURRENT WHEN A CARRIER STORAGE CONDITION EXISTS IN THE TRANSISTOR, A MAGNETIC CORE OF THE RECTANGULAR HYSTERESIS LOOP TYPE CARRYING AN ENERGIZING WINDING WHICH COUPLES IT TO THE SAID OUTPUT CIRCUIT SO THAT COLLECTOR-EMITTER CURRENT FLOWING IN THE OUTPUT CIRCUIT ENERGIZES THE CORE INTO A GIVEN MAGNETIC STATE, MEANS FOR SETTING THE CORE INTO THE OTHER OF ITS TWO STATES, MEANS FOR PRODUCING A SIGNAL WHICH IS DISTINCTIVE OF THE DIRECTION OF CHANGE EACH TIME THE STATE OF MAGNETIZATION OF THE CORE IS CHANGED, AND A UNIDIRECTIONAL PATH WHICH PASSES THAT DISTINCTIVE SIGNAL WHICH CORRESPONDS TO A CHANGE OF THE CORE FROM THE GIVEN STATE CONNECTING THE MEANS FOR PRODUCING DISTINCTIVE SIGNALS TO THE FIRST INPUT CIRCUIT OF THE SUCCEEDING ELEMENTAL CIRCUIT, A COMMON INPUT SOURCE CONNECTED VIA INDIVIDUAL UNIDIRECTIONAL ELEMENTS TO THE SAID SECOND INPUT CIRCUIT OF EACH SAID ELEMENTAL CIRCUIT, A COMMON SUPPLY SOURCE CONNECTED TO THE OUTPUT CIRCUIT OF EACH ELEMENTAL CIRCUIT FOR SUPPLYING THE COLLECTOR-EMITTER CURRENT, A COMMON CLOCK SOURCE CONNECTED TO THE MEANS FOR SETTING EACH CORE AND, A COMMON SHIFT SIGNAL SOURCE CONNECTED TO THE MEANS FOR PRODUCING DISTINCTIVE SIGNALS, THE COMMON SOURCES COMPRISING PULSE SOURCES HAVING A COMMON PULSE RECURRENCE FREQUENCY IN WHICH PULSES FROM THE SHIFT SIGNAL SOURCE PRECEDE AND OVERLAP PULSES FROM THE CLOCK SOURCE WHEREBY THE FIRST INPUT CIRCUIT OF AN ELEMENTAL CIRCUIT IS OPERATED WHEN A CLOCK PULSE CHANGES THE CORE STATE OF THE PRECEDING ELEMENTAL CIRCUIT THE SHIFT SIGNAL PULSE ALREADY PROVIDING A DATUM FOR THE MEANS FOR PRODUCING THE DISTINCTIVE SIGNAL OF THE PRECEDING ELEMENTAL CIRCUIT, PULSES FROM THE COMMON SUPPLY SOURCE SUCCEED CLOCK PULSES SO THAT THE CORE OF THE ELEMENTAL CIRCUIT IS ENERGIZED BY THE ENERGIZING WINDING IN THE OUTPUT CIRCUIT, AND PULSES FROM THE COMMON INPUT SOURCE COMMENCE AFTER THE BEGINNING OF PULSES FROM THE COMMON SUPPLY SOURCE TO DETERMINE THE DURATION OF ENERGIZATIONS OF THE CORE BY EXTRACTING MINORITY CARRIERS.
