Design Improvements for Motion Picture Film Projectors

Christopher L. DuMont, Andrew F. Kurtz, Barry D. Silverstein, David H. Kirkpatrick

This paper describes design improvements developed for motion picture film projectors that are intended to improve the quality of the overall screen image. In particular, new designs for the intermittent, or Geneva mechanism, and for a “Universal” lamp house are described. These improved designs allow the system light efficiency and uniformity to be improved, resulting in significant increases in screen luminance.
