Abstract

372,460. Duplicating sound records. SELENOPHON LICHT-UND TONBILDGES., 46, Rennweg, Vienna. March 6, 1931, No. 7037. Convention date, Jan. 28. [Class 40 (ii).] Photographic sound records are made by copying an original record by the offset printing process. It is stated that a direct transfer of the record by means of suitable photographic copying methods to a metal plate suitable for offset printing avoids the defects inherent in the use of known printing processes such as the relievo or intaglio processes. Specification 331,278, [Class 40 (ii), Phonographs &c.], is referred to.
