Abstract

819,510. Charging with static electricity. ZINDLER, W., [trading as LUMOPRINT ZINDLER K.G.]. March 22, 1957 [March 28, 1956; April 6, 1956], No. 9491/57. Drawings to Specification. Class 35. [Also in Group XX] Class 38 (4). The surface of a sheet comprising a photoconductive layer is given a uniform charge by passing it between a pair of conductive rollers spaced apart at a distance about that of the thickness of the sheet and with the required potential difference maintained between them. Alternatively, a photoconductive layer in the form of a continuous web is given a surface charge by moving it past a corona discharge electrode comprising several wires embedded in an artificial resin body which has cavities for the wires.
