Abstract

319,398. Thornton, J. E. June 21, 1928. Addition to 319,038, [Class 40 (ii), Phonographs&c.]. Adhesives. - The Provisional Specification states that in the manufacture of gramophone records comprising coated layers of paper, double sided records may be produced by cementing together, back to back, two single-sided record discs. The adhesive used may be a mixture of glue or gelatine, molasses or glycerine, and chrome alum or potassium bichromate, in proportions which are specified; it is applied to the paper and allowed to dry, and the sheets are then caused to adhexe under heat and pressure.
