Abstract

1,081,875. Associated working. L. KERTESZ, and L. ACZEL. Aug. 4, 1964, No. 30516/64. Heading G5K. An arrangement for synchronizing a film strip projector 1 to a tape recorder 11 or gramophone 10 comprises a flexible drive-shaft 12 coupled between either the recorder or gramophone and a drive mechanism 14 for moving a perforated tape 15 past a set of contacts 16 and a claw feeder mechanism for moving the film strip forward or backward by one frame each time the contacts close through a perforation in the tape. Depending on the position of a switch 6, which may be manually operated or operated in conjunction, e.g. with the forward and rewind switches of the tape recorder, the contacts either energize a solenoid 2 to move the strip forward via claw feed 4 or solenoid 3 which moves the strip backward via claw feed 5. The perforated tape may include further perforations controlling contacts in the circuits of lights disposed around the picture screen and used to draw attention to particular features in the pictures.
