Abstract

149,649. Messter-Film Ges. Aug. 11, 1919, [Convention date]. Optical - projection apparatus. - Two images are projected on to a screen by one kinematograph projector, one being projected on to an opaque part of the screen, and the other on to a transparent part of the screen. As shown, the projection beam passes through a transparent glass sheet c to a mirror b by which it is reflected on to the transparent part of the screen, and is also reflected by the glass c on to a mirror a, by which it is reflected to the opaque part of the screen. The images are without inversion as viewed from opposite sides of the screen.
