Driving mechanism of a torsional oscillator

Claim 1

AN ELECTROMECHANICAL OSCILLATOR COMPRISING; A BALANCE WHEEL HAVING AN AXLE AND AN UPPER AND LOWER DISC FIXED IN AXIALLY SPACED PARALLEL RELATION THEREON, SAID WHEEL HAVING AN ANGULAR OSCILLATION ARC, SAID UPPER AND LOWER DISCS HAVING COAXIAL SECTOR PORTIONS REMOVED THEREFROM AND HAVING INNER SIDES FACING EACH OTHER, AN ARCUATELY SHAPED PERMANENT MAGNET MOUNTED ON THE INNER SIDE OF SAID UPPER DISC COAXIALLY WITH SAID AXLE AND HAVING THE ENDS THEREOF AT THE OPPOSITE SIDES OF THE SAID SECTOR PORTION, AN ARCUATELY SHAPED PERMANENT MAGNET MOUNTED ON THE INNER SIDE OF SAID LOWER DISC COAXIALLY WITH SAID AXLE AND HAVING THE ENDS THEREOF AT THE OPPOSITE SIDES OF THE SAID SECTOR PORTION, SAID MAGNETS BEING AXIALLY MAGNETIZED AND HAVING POLES OF OPPOSITE POLARITY FACING EACH OTHER AND AT LEAST EQUAL IN CIRCUMFERENTIAL LENGTH TO THE LENGTH OF THE OSCILLATION ARC OF SAID BALANCE WHEEL, SAID MAGNETS ESTABLISHING AN AXIAL FIELD THEREBETWEEN WHICH IS CONTINUOUS CIRCUMFERENTIALLY FROM ONE SIDE OF SAID SECTOR PORTIONS AROUND THE WHEEL TO THE OTHER SIDE OF THE PORTIONS, MAGNETIC SHUNT MEANS NEAR SAID AXLE EXTENDING BETWEEN SAID UPPER AND LOWER DISCS TO REINFORCE THE MAGNETIC EFFECT OF SAID UPPER AND LOWER MAGNETS, COAXIAL EXCITER AND DRIVING COILS MOUNTED IN THE SPACE BETWEEN THE PLANES FORMED BY SAID DISCS AND SAID MAGNETS AND WITHIN THE RADIAL RANGE OF SAID FIELD, AND ELECTRIC CIRCUIT MEANS INTERCONNECTING SAID EXCITER AND DRIVING COILS AND ADAPTED TO SEND A DRIVING CURRENT IMPULSE THROUGH SAID DRIVING COIL TO DEVELOP A DRIVING MAGNETIC IMPULSE ON SAID BALANCE WHEEL IN RESPONSE TO A VOLTAGE INDUCED IN SAID EXCITER COIL BY THE SUDDEN CHANGE IN SAID FIELD WHEN SAID SECTOR PORTIONS PASS WITHIN THE RANGE OF SAID EXCITER COIL, SAID CIRCUIT MEANS COMPRISING A TRANSISTOR AND A VOLTAGE SOURCE, THE CHANGE OF FLUX OF THE MAGNETIC FIELD OF SAID MAGNETS BEING STRONG ENOUGH TO INDUCE A CURRENT IN SAID EXCITER COIL SUFFICIENT TO OPEN SAID TRANSISTOR, SAID TRANSISTOR HAVING A VERY SMALL AMPLIFICATION FACTOR.
