Flyback transformer and transistorized deflection circuit

Claim 1

A TRANSISTORIZED HORIZONTAL DEFLECTION CIRCUIT OF A TELEVISION RECEIVER INCLUDING HORIZONTAL DEFLECTION WINDINGS AND A FLYBACK TRANSFORMER, SAID CIRCUIT NORMALLY SUBJECT TO UNDESIRABLE OSCILLATIONS DURING THE TRACE PORTION OF THE DEFLECTION CYCLE OF SAID CIRCUIT DUE TO LEAKAGE REACTANCES EXHIBITED BY SAID TRANSFORMER, COMPRISING THE COMBINATION OF; A BI-PART FERRITE CORE INCLUDING A PAIR OF SUBSTANTIALLY IDENTICAL C-SHAPED CORE SECTIONS JUXTAPOSED WITH INTERVENING AIR GAPS TO FORM A COMPOSITE CORE OF AN APERTURED RECTANGULAR SHAPE; SAID CORE FORMED WITH ONE LEG THEREOF HAVING A PORTION, EXTENDING ON EITHER SIDE OF THE AIR GAP FORMED IN SAID ONE LEG AT THE JUNCTION OF SAID CORE SECTIONS, WHICH IS CONSTRICTED WITH RESPECT TO THE REMAINING PORTION OF SAID ONE LEG; A HIGH VOLTAGE SECONDARY COIL HAVING A PLURALITY OF TURNS WOUND IN THE CONFIGURATION OF A DISC AROUND THE CONSTRICTED PORTION OF SAID ONE LEG TO EXHIBIT A DESIRED REDUCED STRAY CAPACITANCE BETWEEN SAID SECONDARY COIL AND SAID CORE; A LOW VOLTAGE PRIMARY COIL WOUND PARTIALLY AROUND THE REMAINING PORTION OF SAID ONE LEG AND PARTIALLY AROUND AN ADJACENT LEG OF SAID CORE TO CAUSE SAID TRANSFORMER TO EXHIBIT A DESIRED LEAKAGE INDUCTANCE; AN OUTPUT TRANSISTOR COUPLED ACROSS SAID LOW VOLTAGE PRIMARY COIL AND ALTERNATELY SWITCHED FROM A CUT-OFF CONDITION TO A SATURATED CONDUCTION CONDITION AT THE REPETION RATE OF SAID DEFLECTION CYCLE; AND MEANS COUPING SAID PRIMARY COIL ACROSS SAID HORIZONTAL DEFLECTION WINDINGS; THE INDUCTANCE OF SAID HORIZONTAL DEFLECTION WINDINGS, THE LEAKAGE INDUCTANCE OF SAID FLYBACK TRANSFORMER AND THE STRAY CAPACITANCE OF SAID HIGH VOLTAGE SECONDARY COIL BEING SELECTED TO ELIMINATE UNDESIRABLE OSCILLATIONS DURING THE TRACE PORTION OF THE DEFLECTION CYCLE.
