Synchro-Lite Powered 16mm Projector

R. E. Putman, E. H. Lederer

A new flashtube arrangement, providing projection light for television reproduction from film, is here described in detail. It assures accurate and permanent synchronization of light pulse with intermittent pulldown. Further, since both the intermittent movement and the flashing lamp are controlled by the television vertical pulse, the mechanism can readily be interlocked with other picture sources for interpolation, laps and fades. Travel ghost resulting from motion of film while the light pulse is on is made impossible by the design.
