Patent GB-2053858-A (GB)
Title: Friction paper feeder
IPC: G03G15/00
Filed: 1980-05-27
Abstract: Apparatus for individually feeding sheets in which a friction feed roller 98 positively driven in the direction of feed co-operates with a second friction roller 112 which is urged against the feed roller, e.g. by springs 130, and is provided with a torque biasing it in the reverse direction.

Patent GB-2080735-A (GB)
Title: Electrostatographic process and apparatus
IPC: G03G15/20
Filed: 1980-08-01
Abstract: A photoconductive sheet supported on a drum 20 of electrophotographic apparatus is developed with toner at a developing station 25 and then advanced to a first fixing station 27 where the toner image is fused with the sheet still in position on drum 20 by means of radiant heat from a lamp 60 followed by pressure from a roller 28. When used for electrophotographic duplicating the drum 20 rotates through a first relatively low speed cycle where the photoconductive sheet is charged by corona station 21, imaged at 32, developed by a first developing station 25 and fixed by station 27. In subsequent high speed duplicating cycles of the drum 20 the sheet charged at station 21 is flood exposed at 22 and developed at a second station 24. The developed sheet is rotated to a transfer roller 26 where the toner image is transferred to copy sheet material and is fixed in a copy fixing unit 31. The combination of heat and pressure in the fixing of the master image enables the fixed toner to retain the necessary insulation properties, and there is no warm-up period before fixing can be begun. <IMAGE>
