Abstract: A multistage, crystal-controlled oscillator circuit for a color television receiver provides, from an intermediate stage, a control signal indicative of the presence or absence of burst components in the received signal, with this control signal being utilized to provide ACC and color killer controls for the color television receiver. A feed-forward circuit is provided for the final stage of the oscillator, so that the output signal level obtained from the final stage remains constant, and a provision is made for providing noise immunity of the circuit during both the presence and absence of received burst signal conditions.

Abstract: A color television receiver using direct demodulation of the color and brightness signals is provided with an automatic chroma control circuit for controlling the gain of the color IF amplifier stage in order to prevent the saturation of the demodulated color signals from exceeding the peak brightness signals. The output of the video amplifier is supplied through a peak detector to one input of a differential amplifier, the other input to which is obtained through a second peak detector from the outputs of the color demodulators. The output of the differential amplifier is used to control a switching transistor, which supplies D.C. control signals to the color IF amplifier to control the bias on the final stage thereof. A pair of comparison circuits of the same type are provided, with the second circuit being responsive to the peak blackness signals and the saturation of the color components occurring during the black-going portions of the video signals, while the first comparison circuit compares the white-going peak portions of the video signal with the saturated color appearing during the white-going portions. The blanking circuit operates to disable the comparison circuits during the blanking intervals, so that the automatic chroma control circuit is responsive only to the video signals present during the trace portion of the video signal.

Abstract: A degaussing circuit used in a color television receiver includes a positive temperature coefficient resistor connected in series with the degassing coil, and in addition includes a circuit coupled with the filament winding of the receiver for applying a current through the coil in phase opposition to the current through the positive temperature coefficient resistor. The opposition current is of a magnitude equal to the residual current through the positive temperature coefficient resistor to reduce the current in the degaussing coil to zero after the degaussing operation is complete.

Abstract: A portable meter for tracking any two colors of light emitted from a color cathode-ray tube at all brightness settings includes first and second light-dependent resistors connected in two arms of a bridge circuit in series with one another across a source of DC voltage with the other two arms of the bridge circuit consisting of equal resistors connected in parallel across the light-dependent resistors. The tap of a potentiometer connected between the light-dependent resistors and the tap of a potentiometer connected between the resistors to opposite sides of a DC meter through insulated gate field effect transistors. Light impinging upon each of the light-dependent resistors is passed through a color and a neutral density filter, permitting light of only one color to strike the associated resistor. Provision is made for adjustment of the bridge balance through the potentiometers for conditions of high light, low light and, through an additional arm of the bridge for darkness; so that the meter output is accurate over a wide range of brightness conditions.

Abstract: Remote control tuning of a television set is accomplished by providing a desired DC voltage level derived from an input signal at a particular frequency to a capacitor through a neon tube, and the voltage level stored in the capacitor is coupled to a varactor tuner by a field-effect transistor. In order to insure accurate tuning, the output of an automatic frequency control (AFC) circuit is added to the voltage present on the capacitor to modify the voltage level supplied to the field-effect transistor, thereby modifying the tuning voltage of the tuner causing it to pull on to the correct frequency.

Abstract: An automatic beam intensity limiter circuit for a television receiver having a ''''zero'''' focus cathode-ray tube arrangement employs a current transformer to sense the pulsating DC current in the lead from the high-voltage rectifier to the cathode-ray tube final anode to produce a control voltage indicative of the beam current intensity since the current in the high-voltage lead is proportional to the beam intensity. This control voltage then is utilized to reduce the direct current voltage in the signal path applying the video signal to the cathode-ray tube to limit the beam intensity to a predetermined level.

Abstract: A video signal amplifier is direct current coupled to a cathode ray tube, and an amplifier device, which is sensitive to variations in supply voltage and environmental temperature, is coupled to the video amplifier to compensate conduction changes therein and maintain the brightness level of the image despite these variations. The compensation circuit may be part of a system limiting maximum brightness level of the image.
