Abstract: 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.

bio
Christopher L. DuMont is a senior technical associate in the Entertainment Imaging business unit of Eastman Kodak Co. He has a B.S. from RIT in Imaging Science, and a M.S. in analytical chemistry, also from RIT. He has worked in motion picture systems studies for the last 12 years, and in the military doing remote sensing, prior to working at Kodak. He has worked on developing new negative, intermediate, hybrid and digital products for use in the motion picture industry. Dumont's most recent projects were developing the Kodak PreView System and novel technologies for use in the exhibition industry. Dumont has been the author and presenter of papers at numerous SMPTE conferences. He holds six U.S. patents in the imaging science field for Kodak.
