Claim 1
Independent Claim
215 words
IN A BISTABLE MULTIVIBRATOR CIRCUIT ARRANGEMENT, IN COMBINATION, AT LEAST ONE FLIP-FLOP CIRCUIT INCLUDING TWO CONTROLLABLE ELECTRONIC VALVE MEANS EACH CAPABLE OF BEING ALTERNATIVELY CONDUCTIVE WHILE THE OTHER ONE IS NON-CONDUCTIVE, AND VICE VERSA; AND AT LEAST ONE CONTROL CIRCUIT FOR CONTROLLING SAID VALVE MEANS AND COMPRISING TWO MAGNETIC MEMORY MEANS MAGNETIZED NORMALLY WITH MUTUALLY OPPOSITE MAGNETIC POLARITIES, THE MAGNETIZATION POLARITY OF EITHER OF SAID MAGNETIC MEMORY MEANS BEING REVERSIBLE TO A POLARITY EQUAL TO THAT OF THE OTHER ONE BY APPLICATION OF AN INPUT IMPULSE OF PREDETERMINED POLARITY THERETO, FROM A PRESELECTED ONE OF SAID MAGNETIC POLARITIES TO THE OPPOSITE MAGNETIC POLARITY, SAID MAGNETIC MEMORY MEANS BEING RESPECTIVELY CONNECTED WITH SAID TWO ELECTRONIC VALVE MEANS FOR RENDERING ONE THEREOF CONDUCTIVE AND THE OTHER ONE THEREOF NON-CONDUCTIVE WHEN THE MAGNETIZATION POLARITY OF ONE OF SAID MAGNETIC MEMORY MEANS IS REVERSED, AND FOR RENDERING SAID ONE OF SAID ELECTRONIC VALVE MEANS NON-CONDUCTIVE AND THE OTHER ONE THEREOF CONDUCTIVE WHEN THE MAGNETIZATION POLARITY OF THE OTHER ONE OF SAID MAGNETIC MEMORY MEANS IS REVERSED, AND MEANS FOR REVERSING, AFTER THE CESSATION OF SAID IMPULSE PULSE, UNDER CONTROL OF SAID ELECTRONIC VALVE MEANS THE MAGNETIZATION POLARITY OF THAT ONE OF SAID MAGNETIC MEMORY MEANS WHICH HAS AFTER THE APPLICATION OF SAID INPUT PULSE NOT CHANGED ITS MAGNETIC POLARITY.
