Title: Black level stabilization system for a television receiver

Abstract: 1,008,010. Television. HAZELTINE CORPORATION. July 26, 1963 [Aug. 9, 1962], No. 29796/63. Heading H4F. Relates to a modification of the system described in Specification 1,006,123, and involves the provision of a non-linear element in the circuit by which the video signal is applied to the cathode-ray tube, the element being made responsive to the voltage produced across a resistor through which the tube current flows to cause the transition from correct black level operation with dark scenes, which produce a relatively small D.C. component in the video signal, to substantially deteriorated black level operation with light scenes, which produce a relatively large D.C. component. Thus in Fig. 1 the video signal is applied from amplifier 18 to the cathode of cathode-ray tube 26 via a capacitor 23 shunted by a diode 24 and the cathode circuit of tube is completed via a resistor 31. The diode provides D.C. coupling until the level of D.C. component is such that the voltage produced across resistor 31 equals the D.C. voltage at point 12a. Thereafter, the diode is rendered non-conducting and only A.C. coupling exists via capacitor 23. In a second arrangement, Fig. 4, a direct connection is made from amplifier 18 to the tube grid 29 and the diode 424 is included in the cathode circuit. At low levels of the video D.C. component the diode conducts to short-circuit resistor 431 with a substantially smaller (e.g. one-tenth value) resistor 432. Above the level at which the voltage produced across resistor 431 by the tube current equals the bias potential produced across resistor 432, diode 424 becomes non-conducting and resistor 431 function to introduce substantial D.C. degeneration tube cathode circuit. Further increase in the D.C. component applied between grid and cathode is therefore prevented and the circuit function as though A.C. coupled. According to modification, the diodes shown in Figs. 1 and 4 may be replaced by (1) a reversely connected electrolytic capacitor (in Fig. 1 this also permits capacitor 23 to be dispensed with) and (2) a reversely connected junction diode.
