Abstract

151,084. Beldam, G. W., and Ryall, A. U. B. June 14, 1919. Sponge substitutes.-Rubber sponges are formed so as to have large and small pores in different parts of the sponge, either by vulcanizing together superposed layers of two different compounds which will yield on vulcanization portions having large and small pores, or layers of the same compound, one part of which has been masticated more than the other and forms larger pores on vulcanization. Alternatively, a mixture of the two compounds is vulcanized while supported in a, shallow vessel of water with its lower part dipping into or just above the water. A compound whch yields, on vulcanization, small pores, consists of para rubber, milk of sulphur, lithopone, crimson sulphide of antimony, or vermilion, ceresin wax, fine oil, together with ammonium carbonate or amyl acetate. In a compound for yielding large pores, larger proportions of ammonium carbonate or amyl acetate ara used, precipitated chalk and zinc oxide are used in place of lithopone, and turpantine may partially replace fine oil.
