Abstract

391,457. Gramophone records. DIAMOND, S., 13, Crescent Road, Crouch End, London. Oct. 28, 1931, No. 29827. [Class 40 (ii).] An unbreakable gramophone sound-record is made by securing a photograph on each side of a basic ply or plies of paper, cardboard, or other material, with the photographic print facing outwardly and by covering each of the photographs with a layer of transparent cellulosic material, preferably non-inflammable cellulose acetate. All the plies are stuck together by adhesive and consolidated by heat and pressure when the sound track is impressed on the outer layers. Amyl acetate may be used on the surface of each photograph to secure the outer layers thereto. The amyl acetate combines with the gelatine of the photographic surface, dries out, and under the subsequent heat and pressure ensures a firm union without damaging the photographs. To seal the edges of the composite record the inner and outer peripheries of the outer cellulosic layers are cut so that the inner plies overlap slightly. This enables the uncovered edge margins of the inner plies to fuse with the adherent and seal up any gap between the plies. The photographs are preferably identified with the subject of the sound record. Specifications 17163/02, [Class 40, Electric telegraphs &c.], 247,429, 324,520, and 333,175, [all in Class 40 (ii), Phonographs &c.], are referred to.
