Transistor deflection system with linearizing circuit

Claim 1

A GENERATOR SYSTEM FOR PROVIDING CURRENT FOR THE HORIZONTAL DEFLECTION COILS OF A CATHODE RAY TUBE USED IN TELEVISION APPARATUS INCLUDING IN COMBINATION, OSCILLATOR MEANS FOR PROVIDING PULSES RECURRING AT THE HORIZONTAL DEFLECTION FREQUENCY, A TRANSISTOR HAVING BASE, EMITTER AND COLLECTOR ELECTRODES, MEANS COUPLING SAID BASE, EMITTER AND ELECTRODES TO SAID OSCILLATOR, DIRECT CURRENT POTENTIAL SUPPLY MEANS, A CHOKE COIL HAVING FIRST AND SECOND TERMINALS AND AN INTERMEDIATE TAP, A RESISTEOR HAVING FIRST AND SECOND TERMINALS WITH SAID FIRST TERMINAL THEREOF CONNECTED TO SAID SECOND TERMINAL OF SAID COIL, MEANS CONNECTING THE DEFLECTION COILS BETWEEN SAID TAP ON SAID CHOKE COIL AND SAID SECOND TERMINAL OF SAID RESISTOR, AND CIRCUIT MEANS CONNECTING SAID POTENTIAL SUPPLY MEANS BETWEEN SAID COLLECTOR AND EMIUTTER ELECTRODES OF SAID TRANSISTOR, SAID CIRCUIT MEANS PROVIDING A PATH FOR DIRECT CURRENT FLOW THROUGH SAID COIL AND SAID RESISTOR AND EXTENDING FROM SAID FIRST TERMINAL OF SAID COIL TO SAID SECOND TERMINAL OF SAID RESISTOR, SAND TRANSISTOR BEING RENDERED CONDUCTIVE BY SAID PULSES APPLIED THERETO FROM SAID OSCILLATOR MEANS TO APPLY A CURRENT WAVE OF SAWTOOTH FORM THROUGH THE DEFLECTION COILS.
