Abstract

731,232. Automatic synchronizing systems for sound film apparatus. SEIFFERT, M. Oct. 2, 1953 [Oct. 9, 1952], No. 27161/53. Drawings to Specification. Class 38 (4). [Also in Group XXXVIII] In a sound film apparatus comprising a magnetic sound reproducer and a cinematograph projector driven by separate motors and using separate sound and image bands, the speed of one of the motors is regulated by a device responsive to changes of tension in one of the bands, e.g. by a variable series resistance, controlled by a movable spring-loaded arm displaced by changes in the length of a loop in one of the bands. As described, the sound and image bands are fed on to a single take-up reel.
