Abstract

331,030. Sartelstone, L. March 13, 1929, [Convention date]. Compound transparent sheets.-A process for the manufacture of compound transparencies composed of sheets of glass and celluloid consists of seasoning the celluloid for five days in a current of air at 98‹ F. about, cleaning the celluloid of dust by means of a rubber which is an electric conductor and removes the electricity generated by the friction, surfacing the sheet with a free flowing solution of celluloid which is then dried at 150‹ to 160‹ F. for 30 minutes and finally interposing the sheet between two glass sheets the contacting surfaces of which have been coated thickly with castor oil or other vegetable oil at a pressure of 150 lbs. per square in. for about 4¢ minutes and at a temperature of 240‹ to 250‹ F. The celluloid sheet used in the process should contain 30 per cent or more of camphor.
