A Non-Intermittent Projector for Television Film Transmission

H. S. Bamford

A continuous machine is described for the projection of images from film into the pick-up camera for television transmission of motion pictures. The camera tube can be either of the instantaneous or the storage type. The images are incident upon the cathode during scansion and the optical image transition interval is less than the scanning flyback interval with which it is synchronized. Certain advantages are taken in the construction of a double-lens disk type of optical compensator to obtain an image steadiness determined only by the number of lenses per disk, such errors as are introduced by lens setting and gearing being negligible.
