Abstract
807,798. Charging with static electricity. RADIO CORPORATION OF AMERICA. Feb. 9, 1956 [March 3, 1955], No. 4130/56. Class 35. An insulating sheet which may carry a photoconductive layer is given a uniform electrostatic charge by passing it between two corona electrodes 8, 10 to which high voltages of opposite polarity are applied, the sheet being guided so as to be spaced from both electrodes. As shown, the corona electrodes 8, 10 each comprise a series of fine wires 12, 16, respectively. They may be surrounded by shields 20 which are connected to earth.
