Magnetic oscillator apparatus having means for minimizing nonlinearities in the square wave output

Claim 1

A MAGNETIC OSCILLATOR COMPRISING: A PAIR OF INPUT TERMINALS FOR CONNECTION TO A SOURCE OF ELECTRIC POTENTIAL; MAGNETIC TIMING MEANS INCLUDING A SATURABLE CORE AND A WINDING WHICH INCLUDES FIRST AND SECOND PORTIONS ON SAID CORE; BISTABLE SWITCHING MEANS, CONNECTED TO SAID WINDING AND TO SAID PAIR OF INPUT TERMINALS FOR ALTERNATELY DRIVING THE CURRENT THROUGH SAID WINDING IN FIRST AND SECOND DIRECTIONS, THE DIRECTION OF SAID CURRENT DEPENDING ON THE STATE OF SAID BISTABLE SWITCHING MEANS; SENSING MEANS CONNECTED ALTERNATELY TO SAID FIRST AND SECOND PORTIONS OF SAID TIMING MEANS FOR SENSING FLUX CHANGES IN SAID CORE AND PROVIDING A FEEDBACK SIGNAL INDICATIVE OF THE FLUX CHANGES; AND CONTROL MEANS CONNECTED TO SAID WINDING AND ADAPTED TO RECEIVE SAID FEEDBACK SIGNAL FROM SAID SENSING MEANS FOR VARYING THE VOLTAGE ACROSS THE OTHER PORTION OF SAID WINDING FROM THAT PORTION WHICH IS CONNECTED TO SAID SENSING MEANS AND ATTAINING A CONTROLLED RATE OF FLUX CHANGES IN THE CORE.
