Logical circuits

Claim 1

A LOGIC DEVICE COMPRISING FIRST AND SECOND MAGNETIC CORES EACH HAVING TWO STATES OF MAGNETIC REMANENCE RESPECTIVELY REPRESENTING ZERO AND ONE, AN INPUT WINDING COUPLED TO SAID FIRST CORE, AN OUTPUT WINDING COUPLED TO SAID SECOND CORE, A FIRST DRIVE WINDING HAVING TWO SERIALLY CONNECTED SECTIONS, ONE OF SAID SECTIONS BEING INDUCTIVELY COUPLED TO SAID FIRST CORE AND THE OTHER OF SAID SECTIONS BEING COUPLED TO SAID SECOND CORE WITH A WINDING SENSE OPPOSITE TO THAT OF SAID FIRST SECTION ON SAID FIRST CORE, A SECOND DRIVE WINDING INDUCTIVELY COUPLED TO SAID SECOND CORE, A THIRD WINDING CONNECTED IN PARALLEL WITH SAID FIRST DRIVE WINDING AND INDUCTIVELY COUPLED TO SAID SECOND CORE, A RECTIFIER CONNECTED IN SERIES WITH SAID THIRD WINDING, AND MEANS FOR ALTERNATELY EXCITING WITH CURRENT SAID FIRST AND SECOND DRIVE WINDINGS FOR RESPECTIVELY DRIVING SAID FIRST CORE FROM A ONE TO A ZERO STATE OF MAGNETIC REMANENCE AND FOR DRIVING SAID SECOND CORE FROM A ZERO TO A ONE STATE OF MAGNETIC REMANENCE AND FOR DRIVING SAID SECOND CORE FROM ITS ONE TO ITS ZERO STATE OF MAGNETIC REMANENCE WHEREBY UPON SAID FIRST CORE BEING DRIVEN TO ITS ONE STATE OF MAGNETIC REMANENCE RESPONSIVE TO EXCITATION OF ITS INPUT WINDING NO OUTPUT APPEARS IN SAID OUTPUT WINDING UPON THE SUCCEEDING EXCITATION OF SAID SECOND DRIVE WINDING.
