Abstract
1,052,019. Cleaning electrophotographic plates. L. F.W. LAWES, N. G. SHREEVE and N. MIHALIK. June 16, 1965 [March 16, 1964], No. 10933/64. Heading G2H. Surfaces carrying developed electrostatic images are cleaned by brushes 2, 3, 4 engaging flick - edges 5, 6 and 7 which discharge powder, picked up by the brushes, into a chamber 20. A removable slide 9 Fig. 2 (not shown) of insulating material retains powder by electrostatic force. Alternatively the chamber 20 may be connected to a fan 11 Fig. 3 (not shown) which draws powder laden air through a filter 12. In another embodiment, Fig. 4 (not shown) an electrostatic precipitator cleans discharged air.
