Abstract

23,406. Johnson, J. V., [American Graphophone Co.]. Nov. 7. Graphophones.-The ingredients used in making the blanks for graphophones &c., either separately, or in partial mixture, or preferably all mixed together, are subjected to a temperature between 450‹ F. and 475‹ F., when all water of crystallization is driven off, and all fibrous or other organic matter is destroyed. The temperature of the mixture is then allowed to fall about 100 degrees, and the mass moulded into shape, the material producing being amorphous and homogeneous. As an illustration of the process, the Specification mentions a mixture of stearic acid, aluminic hydrate, caustic soda lye, and paraffin, ozokerit, or similar material in definite proportions, such that only partial saponification of the stearic acid is produced.
