Abstract

408,001. Sound and like records. MILLER, J. A., 4627, 193rd Street, Flushing, New York, U.S.A. Sept. 26, 1932, No. 247/34. Convention date, Sept. 30, 1931. Divided on 411,144 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 1, 1932. [Class 40 (ii).] A hill-and-dale record of sound or like vibrations, which record is suitable for optical reproduction and is of the varying- density type, is made on a carrier, preferably a film, by removing with a vibrating cutter parts of a layer consisting of an exposed and subsequently developed photographic emulsion. The emulsion layer 10 is preferably applied to a transparent backing 9, e.g. of celluloid, and is sufficiently thick to ensure that the recording tool 11 does not cut into the hard backing 9. The record may be made on disc or cylindrical carriers.
