Vertical deflection and blanking circuit

Claim 1

A CIRCUIT FOR THE PICTURE TUBE OF A TELEVISION SET COMPRISING: AN AMPLIFYING DEVICE INCLUDING AN OUTPUT ELECTRODE AND A CONTROL ELECTRODE; A TRANSFORMER INCLUDING A FIRST WINDING COUPLED TO SAID OUTPUT ELECTRODE, A SECOND WINDING COUPLED BETWEEN SAID FIRST WINDING AND THE DEFLECTION COIL OF SAID PICTURE TUBE, AND A THIRD WINDING COUPLED TO SAID FIRST AND SECOND WINDINGS, SAID THIRD WINDING HAVING A PREDETERMINED NUMBER OF TURNS TO PRODUCE THEREACROSS PULSES OF GIVEN MAGNITUDE TO PROVIDE BLANKING PULSES; FIRST MEANS COUPLED TO SAID THIRD WINDING TO COUPLE TO SAID BLANKING PULSES TO AN ACCELERATING ANODE OF SAID PICTURE TUBE; A FIRST CAPACITOR COUPLED TO SAID CONTROL ELECTRODE; SECOND MEANS COUPLED ACROSS SAID THIRD WINDING TO REDUCE SAID GIVEN MAGNITUDE; A CHARGING CIRCUIT INCLUDING A FIRST RESISTOR COUPLED BETWEEN SAID CAPACITOR AND SAID SECOND MEANS, AND A VOLTAGE SOURCE COUPLED TO SAID SECOND MEANS; AND THIRD MEANS COUPLED TO SAID CAPACITOR IN SAID CHARGING CIRCUIT TO PRODUCE A CONTROL VOLTAGE FOR SAID AMPLIFYING DEVICE AND A PREDETERMINED DEFLECTION CURRENT FOR THE DEFLECTION COIL OF SAID PICTURE TUBE.
