Abstract

605,014. Sound - film apparatus. ETABLISSEMENTS E. BRANDT. Dec. 12, 1945, No. 33565. Convention date, Dec. 26, 1944. [Class 40 (ii)] In a sound-film apparatus, a device for maintaining uniform speed of the film past the translation point consists of a driven sprocket E which draws film over a drum D, the shaft of which is coupled, via gear-wheels C and B and a resilient coupling J, to a shaft carrying a flywheel K and another drum A, comprising the translation point, over which a loop M, N of the film passes.
