Transistor circuit for generating pulses in alternate directions

Claim 1

A SYSTEM FOR PROVIDING CURRENT FLOW THROUGH A COIL IN ALTERNATE DIRECTIONS COMPRISING, A FIRST AND SECOND PAIR OF TRANSISTORS WITH EACH TRANSISTOR HAVING AT LEAST BASE, AN EMITTER AND A COLLECTOR, THE COLLECTOR OF A FIRST TRANSISTOR OF SAID FIRST PAIR BEING CONNECTED TO THE COLLECTOR OF A FIRST TRANSISTOR OF SAID SECOND PAIR AT A FIRST JUNCTION, THE COLLECTOR OF SAID SECOND TRANSISTOR OF SAID FIRST PAIR BEING CONNECTED TO THE COLLECTOR OF A SECOND TRANSISTOR OF SAID SECOND PAIR AT A SECOND JUNCTION, INPUT CIRCUIT MEANS FOR NORMALLY MAINTAINING NONCONDUCTIVE SAID FIRST PAIR OF TRANSISTORS, MEANS INCLUDING IMPEDANCE MEANS CROSS-CONNECTING SAID SECOND PAIR OF TRANSISTORS AND CONNECTED TO SAID FIRST AND SECOND JUNCTIONS FOR MAINTAINING NON-CONDUCTIVE SAID SECOND PAIR OF TRANSISTORS WHEN SAID FIRST PAIR OF TRANSISTORS IS NON-CONDUCTIVE, SAID COIL BEING CONNECTED BETWEEN SAID FIRST AND SAID SECOND JUNCTIONS, AND MEANS CONNECTED TO SAID INPUT CIRCUIT MEANS FOR APPLYING INPUT PULSES ALTERNATELY TO SAID FIRST AND SECOND TRANSISTORS OF SAID FIRST PAIR TO (1) TURN ON SAID FIRST TRANSISTOR OF SAID FIRST PAIR THEREBY TO TURN ON SAID SECOND TRANSISTOR OF SAID SECOND PAIR TO PROVIDE CURRENT FLOW THROUGH SAID COIL IN A FIRST DIRECTION AND (2) TO TURN ON SAID SECOND TRANSISTOR OF SAID FIRST PAIR THEREBY TO TURN ON SAID FIRST TRANSISTOR OF SAID SECOND PAIR TO PROVIDE CU RRENT FLOW THROUGH SAID COIL IN A SECOND DIRECTION.

Claim 2

A SYSTEM FOR PROVIDING CURRENT FLOW THROUGH A COIL IN ALTERNATE DIRECTIONS COMPRISING, A FIRST AND SECOND PAIR OF TRANSISTORS WITH EACH TRANSISTOR HAVING AT LEAST BASE, AN EMITTER AND A COLLECTOR, THE COLLECTOR OF A FIRST TRANSISTOR OF SAID FIRST PAIR BEING CONNECTED TO THE COLLECTOR OF A FIRST TRANSISTOR OF SAID SECOND PAIR AT A FIRST JUNCTION, THE COLLECTOR OF SAID SECOND TRANSISTOR OF SAID FIRST PAIR BEING CONNECTED TO THE COLLECTOR OF A SECOND TRANSISTOR OF SAID SECOND PAIR AT A SECOND JUNCTION, INPUT CIRCUIT MEANS FOR NORMALLY MAINTAINING NONCONDUCTIVE SAID FIRST PAIR OF TRANSISTORS, MEANS INCLUDING IMPEDANCE MEANS CROSS-CONNECTING SAID SECOND PAIR OF TRANSISTORS AND CONNECTED TO SAID FIRST AND SECOND JUNCTIONS FOR MAINTAINING NON-CONDUCTIVE SAID SECOND PAIR OF TRANSISTORS WHEN SAID FIRST PAIR OF TRANSISTORS IS NON-CONDUCTIVE, SAID COIL BEING CONNECTED BETWEEN SAID FIRST AND SAID SECOND JUNCTIONS, AND MEANS CONNECTED TO SAID INPUT CIRCUIT MEANS FOR APPLYING INPUT PULSES ALTERNATELY TO SAID FIRST AND SECOND TRANSISTORS OF SAID FIRST PAIR TO (1) TURN ON SAID FIRST TRANSISTOR OF SAID FIRST PAIR THEREBY TO TURN ON SAID SECOND TRANSISTOR OF SAID SECOND PAIR TO PROVIDE CURRENT FLOW THROUGH SAID COIL IN A FIRST DIRECTION AND (2) TO TURN ON SAID SECOND TRANSISTOR OF SAID FIRST PAIR THEREBY TO TURN ON SAID FIRST TRANSISTOR OF SAID SECOND PAIR TO PROVIDE CU RRENT FLOW THROUGH SAID COIL IN A SECOND DIRECTION.
