Abstract

836,449. Combined sound and picture apparatus. HANDLER, A., and VOCKENHUBER, K. March 12, 1957 [March 27, 1956], No. 8073/57. Class 40 (2). [Also in Group XXXV] A device for synchronizing a picture projector with a separate independently-driven magnetic tape recording apparatus. The magnetic tape 6 is drawn over the sound head 7 by the roller 25 and before being wound on the take-up spool 4 passes over a guide roller 16 and a roller 15, carried on a pivoted lever 19, then between a pressure roller 14 and a second driven roller 12. The roller 12 is keyed to a shaft 11 having at its other end a sprocket 9 driven by the cine-film 2. The diameter of the roller 12 is such that if the film and tape are running at the correct relative speeds the length of the loop of tape 6<1> is constant but a difference in the two speeds causes the loop to alter in length and rotates lever 19 and shaft 18 which carries the slider 20 of rheostat 21 connected in the projector motor circuit. Limit switches 23 and 24 co-operate with contact 22 to stop one or both pieces of apparatus at the end of the film.
