Claim 1

IN A CIRCUIT FOR CONTROLLING THE IMPEDANCE PRESENTED TO A DRIVE CURRENT SOURCE, THE COMBINATION OF: A UNITARY BLOCK OF MAGNETIC MATERIAL HAVING DRIVE AND CONTROL CURRENT AXES THERETHROUGH SUBSTANTIALLY PERPENDICULAR TO EACH OTHER, AND INCLUDING A FIRST FLUX PATH ABOUT THE DRIVE CURRENT AXIS, AND A SECOND FLUX PATH ABOUT THE CONTROL CURRENT AXIS PERPENDICULAR TO THE FIRST FLUX PATH; A VARIABLE IMPEDANCE CONDUCTOR POSITIONED ALONG SAID DRIVE CURRENT AXIS FOR COUPLING TO THE DRIVE CURRENT SOURCE; A CONTROL CURRENT CONDUCTOR POSITIONED ALONG THE CONTROL CURRENT AXIS; A THIRD CONDUCTOR POSITIONED ALONG THE CONTROL CURRENT AXIS, WITH A CLOSED CIRCUIT HAVING APPROXIMATELY ZERO RESISTANCE IN AT LEAST ONE DIRECTION CONNECTED ACROSS THE THIRD CONDUCTOR; AND A CONTROL CURRENT SOURCE FOR GENERATING A CURRENT IN THE CONTROL CURRENT CONDUCTOR TO PRODUCE A MAGNETIC FLUX IN SAID SECOND PATH FOR SELECTIVELY SETTING THE MAGNETIC INDUCTION STATE IN THE SECOND PATH AT SUBSTANTIALLY ZERO AND AT A HIGH VALUE WITH THE HIGH INDUCTION STATE PROVIDING COUPLING OF THE CLOSED CIRCUIT IMPEDANCE OF THE THIRD CONDUCTOR TO THE VARIABLE IMPEDANCE CONDUCTOR AND WITH THE ZERO INDUCTION STATE PREVENTING SUCH COUPLING AND PRODUCING A HIGH IMPEDANCE TO CURRENT IN SAID VARIABLE IMPEDANCE CONDUCTOR.
