5279. Cohen, E. S. Ali-. March 9. Sizes.-The product described in Specification No. 8071, A.D. 1902, is heated at a temperature of 160-180‹ C. with a dried and purified vegetable oil, oxidized or not. The resulting mass, after vulcanization, is kneaded under the influence of heat and pressure. The product resembles vulcanized india-rubber, and may be used for electric insulation, for waterproofing and otherwise protecting paper, fabrics, &c., and for adding to india-rubber and gutta-percha. The vulcanizing process may be omitted and the unvulcanized product may be diluted with benzine or other solvent and used for impregnating porous materials, such as paper and textile fabrics, for waterproofing, insulating, &c.
