Abstract: A deflection generator (21) of a television receiver includes a trace switch (27) that during normal mode of operation is switched at a deflection rate to generate scanning current in a deflection winding (LH). The deflection generator includes a retrace capacitance (CR) for forming a retrace resonant circuit with the deflection winding to produce a retrace pulse voltage. A load circuit (at Vb) is coupled to the deflection generator and is energized by the retrace pulse voltage during normal operation. A remote control circuit (30) develops a remote ON-OFF command signal. A standby circuit (Q2) is series coupled with the deflection generator (21) and is responsive to a remote ON-OFF command signal for producing substantially a short circuit through the trace switch (27) upon receipt of the OFF-state of the command signal. The retrace pulse voltage then collapses and places the load circuit in a standby mode of operation.

Abstract: A raster centering circuit derives it power from a deflection amplifier and has reduced power consumption through the use of energy storage capacitance. In one embodiment a first capacitor coupled to the deflection winding is charged by deflection current through a first diode during a first portion of the trace interval and discharges through a centering control during a second portion of the trace interval, providing a centering current of one polarlity through the deflection winding. A second capacitor coupled to the deflection circuit charges through a second diode during the retrace interval and discharges through the centering control during the trace interval for producing a centering current of the opposite polarlity through the deflection winding. Adjustment of the centering control determines the net flow of centering current through the deflection winding. In another embodiment the junction of the deflection winding and the deflection winding coupling capacitor is coupled through the centering control and through two parallel oppositely poled diodes to ground such that adjustment of the centering control provides a greater deflection current flow through one of the diodes for producing a negative or positive voltage at the capacitor and winding junction for causing the desired polarity centering current flow through the deflection winding.

Abstract: 1460569 Transistor amplifiers RCA CORPORATION 12 Nov 1973 [13 Nov 1972] 52362/72 Heading H3T An amplifier circuit having constant current consumption comprises first and second transistors 101, 105 series connected between supply terminals, utilization means 104 coupled in parallel across the first transistor 101 and a D.C. impedance 102 monitoring the current through the first transistor and controlling via a third transistor 106 and a resistor 108 the bias to the second transistor 105 so as to provide constant current flow I 0 therethrough. As shown the D.C. power supply for an audio pre-amplifier 80 and output amplifier 100 is obtained by rectification of horizontal deflection flyback pulses from a T.V. receiver and the arrangement maintains the current drawn therefrom constant. Thermal stability of I 0 is achieved by the diodes 109 and 110. The audio amplifier is protected against a short circuit across the speaker 104 since the maximum current can only reach the value I 0 .

Abstract: First and second resonant circuits store energy from a supply. First and second switches are respectively coupled to the first and second resonant circuits for generating resonant oscillations in the resonant circuits. A deflection circuit coupled to one of the resonant circuits has energy transferred to the deflection circuit during the resonant oscillations. A control circuit coupled to the switches varies the conduction angle overlap of the resonant oscillations in the resonant circuits for providing energy regulation.
