Reinhold Deml, Dieter Giglberger, Ulrich Greis: Daylight projection screen and method and apparatus for making the same. Agfa Gevaert, Michael J Striker, October 23, 1979: US04172219 (37 worldwide citation)

A layer of material which absorbs incident focussed laser light and undergoes a resultant heating is arranged in the focal plane of a lens matrix. Laser light is projected onto such layer through the lens matrix itself. The laser light is focussed by the lens elements of the lens matrix onto the lay ...

Robert Kohler, Jorn Muller, Dieter Giglberger, Freidrich Bestenreiner: Apparatus for electrophotographic copying with means for effecting image penetration through the copy carriers. Agfa Gevaert, Michael J Striker, May 27, 1980: US04204731 (6 worldwide citation)

An electrostatic charge is applied to a charge carrier and the latter is thereupon contacted with one side of a sheet-material copy carrier. Thereafter, an original is imaged onto the charge carrier to produce thereon a latent electrostatic image field which penetrates the copy carrier, whereupon th ...
