Abstract
363,998. Copying sound records. KLANGFILM GES., 4, Askanischer Platz, Berlin. June 26, 1930, No. 19519. Convention date, June 26, 1929. [Class 40 (ii).] Sound records on films, plates, discs, or other carriers are transferred simultaneously by photographic recording apparatus on to a single blank so that the latter has the records lying adjacent to each other. As shown, sound records on films T<1>, T<2> are printed side by side on a film T, the light rays from sources L<1>, L<2> passing through the films T<1>, T2 respectively and through a light slit S and optical system O. The width of each record may be varied and the intensity of the records may be varied by varying the strengths of the sources L<1>, L<2>, or by introducing screens into the light paths. The sound records on the film T or the sound records being combined may be simultaneously listened to. In the latter case the films T<1> T2 have testing devices A<1>, A2, acting upon an amplifier V and listening device L. In Fig. 2, three records are shown side by side on a single film.
