Abstract

475,260. Driving sound-films. BRITISH THOMSON-HOUSTON CO., Ltd. (Allgemeine Elektricitõts-Ges.) June 22, 1937, No. 17373. Addition to 456,884. [Class 40 (ii)] [Also in Group XX] In film-driving apparatus according to the parent Specification, comprising a smooth roller 1 imparting rotation to a roller 2 with a resilient coating, the film 5 being engaged over its whole width by the roller 2, the path of the film before it engages both rollers is such that it does not engage the roller 2. The film may first engage the roller 1, and is drawn over a sound recording or reproducing device 3 and wound on a spool 4.
