C. L. DuMont, A. F. Kurtz, B. D. Silverstein, D. H. Kirkpatrick

This paper describes improvements developed for motion picture film projectors, in particular, new designs for the intermittent, or Geneva mechanism, and for a Universal lamp house. These new designs are intended to improve the quality of the overall screen image as well as light efficiency and uniformity, resulting in significant increases in screen luminance.
