Abstract
377,095. Combined sound and picture films. I. G. FARBENINDUSTRIE AKT.- GES., Frankfort-on-Main, Germany. Jan. 7, 1932, No. 504. Convention date, Jan. 7, 1931. [Class 40 (ii).] In the process of printing by optical reduction on a substandard film sound and picture records from standard film, the standard film is printed intermittently and so that every third picture is not printed and the standard sound film is printed whilst driven at a uniform but higher speed than the sub-standard film whereby on reproduction from this film at a reduced speed the reproduction of corresponding sound and picture records is similar as regards time to reproduction from a standard film and the sound is reproduced at the correct speed. The picture omissions in printing may be effected by interrupting the travel of the sub-standard film at each third change and simultaneously obstructing the picture window, or by advancing the standard picture negative film at each third change by an amount equal to two picture spaces.
