Claim 1
Independent Claim
138 words
A BISTABLE AMPLIFIER COMPRISING A MAGNETIC AMPLIFIER, A SATURABLE TRANSFORMER, A COUPLING MEANS AND A FLIP-FLOP ELEMENT HAVING AN INPUT MEANS; SAID SATURATING TRANSFORMER HAVING INPUT MEANS FOR RECEIVING A.C. AND OUTPUT MEANS CONNECTED TO ENERGIZE THE MAGNETIC AMPLIFIER; SAID MAGNETIC AMPLIFIER HAVING TWO SATURABLE MAGNETIC CORES EACH HAVING INDUCTIVELY DISPOSED THEREON A GATING WINDING; SAID GATING WINDINGS BEING CONNECTED IN CIRCUIT RELATIONSHIP WITH THE SATURATING TRANSFORMER OUTPUT MEANS AND SAID COUPLING MEANS; SAID COUPLING MEANS COUPLING AN OUTPUT FROM SAID GATING WINDING TO SAID INPUT MEANS OF SAID FLIP-FLOP ELEMENT; MEANS FOR BIASING EACH SAID SATURABLE MAGNETIC CORE TO FIRE AT SUBSTANTIALLY THE SAME TIME AS SAID SATURATING TRANSFORMER SATURATES; AND MEANS FOR APPLYING A CONTROL SIGNAL TO SAID MAGNETIC AMPLIFIER WHICH IS OPERATIVE TO FIRE SAID SATURABLE CORES PRIOR TO THE SATURATION OF SAID SATURATING TRANSFORMER.
