Electrical circuit for translating a mechanical variation into an electrical variation

Claim 1

AN ELECTRICAL CIRCUIT FOR TRANSLATING A MECHANICAL VARIATION OF CONDUCTIVE MATERIAL TRAVELING IN A FIXED PATH INTO AN ELECTRICAL VARIATION, INCLUDING AN OSCILLATOR ELECTRICALLY CONNECTED TO BOTH SIDES OF A SOURCE OF ELECTRICALLY AND INCLUDING A COIL IN PROXIMITY TO THE PATH OF TRAVEL OF THE MECHANICAL VARIATION AND SAID OSCILLATOR GENERATING SINUSOIDAL WAVES INTERRUPTED BY THE TRAVEL OF THE CONDUCTIVE MATERIAL OF THE MECHANICAL VARIATION IN PROXIMITY TO THE COIL, A DIODE DETECTOR ELECTRICALLY CONNECTED IN CIRCUIT WITH SAID OSCILLATOR TO RECTIFY AND FILTER THE FREQUENCY VARIATION OF THE VAVES GENERATED BY THE OSCILLATOR, AN AMPLIFIER ELECTRICALLY CONNECTED IN CIRCUIT WITH SAID DIODE DETECTOR, A SENSITIVE RELAY ELECTRICALLY CONNECTED IN CIRCUIT WITH THE AMPLIFIER AND ENERGIZED AND DE-ENERGIZED BY SAID AMPLIFIER DEPENDING UPON THE DEGREE OF PROXIMITY BETWEEN THE CONDUCTIVE MATERIAL OF THE MECHANICAL VARIATION AND THE COIL, A SATURABLE TRANSFORMER ELECTRICALLY CONNECTED IN CIRCUIT WITH SAID SENSITIVE RELAY TO PRODUCE A CURRENT FLOW IN ONE DIRECTION WHEN THE RELAY IS ENERGIZED AND A CURRENT FLOW IN THE OPPOSITE DIRECTION WHEN THE RELAY IS DE-ENERGIZED, AND A RECTIFIER ELECTRICALLY CONNECTED TO SAID TRANSFORMER AND CONSTITUTING THE OUTPUT OF THE ELECTRICAL CIRCUIT.
