Abstract

308,616. Flatz, H., (Assignee. of Feldner, F.). March 24. 1928, [Convention date]. Optical-projection apparatus.-Kinematograph or other images are projected from diapositives a, b, c, arranged one behind the other, on to a corresponding number of screens d, e, f, similarly arranged, to produce a. relief effect. The effective parts of the screens are of such shapes that, if assembled in one plane, they would fit together to form one complete screen, and the complete image is carried by the diapositives in parts similar in shape to the effective parts of the screens. The screens may be of glass which is frosted at the parts which are to be effective.
