Abstract

352,825. Associated sound and picture films. FREUND, B., 30, M³nchenerstrasse, Sch÷neberg, Berlin. Aug. 20, 1929, No. 28780/30. Convention date, Aug. 20, 1928. Divided on 317,735, [Class 40 (ii), Phonographs &c.]. [Class 40 (ii).] Relates to the production of associated sound and picture films. According to the invention, the picture record is made photographically, in known manner, and the accompanying sound record is first made non-optically (e.g. magnetically), the said non-optical sound record being then converted in any known way into a photographic sound record which is used in co-operation with the picture record. From the original sound record, a photographic record may be obtained on a film which may be used in conjunction with the separate picture film ; or the photographic sound record derived from the original record may be printed on to a reserved margin of the undeveloped film on which the pictures have been photographed, the development of the sound and picture records on the film being then effected simultaneously. Alternatively, the preparation of a separate optical sound record may be avoided by converting the non-optical record directly into a photographic record on the picture film. Specification 243,375, [Class 40 (ii), Phonographs &c.], is referred to.
