IPC: G03G15/02
Filed: 1965-11-25
Abstract: 1,128,618. Charging xerographic plates. RANK XEROX Ltd. Nov.25, 1965 [Dec.4, 1964(2)], No.50071/65. Heading G2H. An apparatus for charging xerographic plates, connected to an A. C. source, has a capacitor 80, Fig.2 in series with the plate 10, 12 to be charged and a control valve 86 which controls a switch 96 which connects a high voltage D.C. supply for energization from the A.C. source. The apparatus includes wires 54, e.g. of stainless steel mounted on a frame (14) Fig.1 (not shown). A control circuit 66, Fig.2, having triodes 68, 69 controls the voltage applied to the primary winding TP-1 of a transformer. The grid of triode 68 is connected to the secondary winding TS-2 of the transformer. A pressure sensitive bellows 74 controls the setting of potentiometer 72 in accordance with ambient pressures. A rectifier circuit 60, energized through secondary winding TS-1 has diodes 76 and 78 which supply wires 54. The capacitor 80 is connected to the plate 10, 12 and a voltage divider having resistors 82, 83. The junction of resistors is connected to the grid 85 of the thyratron 86. A relay 94 controlling switches 96, 98 is energized when thyratron 86 conducts. The thyratron 86 conducts when the voltage drop across capacitor reaches a predetermined level related to the required charging of the plate 10, 12. In a modification Fig. 5 (not shown) D.C. and A.C. potential is applied to a plate (110,112) which is charged in series with a capacitor (180). A switch (168) controlled by a relay (166) opens the A.C. and D.C. circuits when the plate potential reaches the required level. The relay (166) is controlled by the grid potential of a pentode (176).
