Abstract
13,792. Eberhard, R. June 29. [Patent of Addition to No. 12,980, A.D. 1908.] Wood, treating for preserving, waterproofing, &c. -In the process described in the parent Specification, in place of chrome salts, chrome acids are used, or, in conjunction with very small quantities of such acids or chrome salts, very small quantities of one or more compounds of the following categories : bases soluble in alkalies, salts of such bases, salts, oxides, and hydrates of heavy metals soluble in alkalies, boric acid, oxalic acid, or. ammonium oxalate. The following are examples of such bodies : stannous or stannic chloride, stannic hydrate, sodium stannate, tin sulphides, pink salt and other tin salts ; lead oxide, peroxide, carbonate, acetate, and other lead salts ; potassium manganate and permanganate; zinc oxide, hydrate, and salts ; aluminium hydrate, chloride, and phosphate and other aluminium salts ; aluminium salts in conjunction with tartaric and citric acids and alkali ; borax, and borax in conjunction with barium or calcium chloride or magnesium sulphate; sodium phosphate. The corresponding doublesalts can be used if soluble in alkalis. Some of the salts precipitate silicates from the water-glass, but the precipitate redissolves in a little alkaline lye. In an example 0À05 per cent of chromic acid, and 0À25 per cent of freshly precipitated lead hydrate dissolved in alkaline lye, are added to water-glass of 20‹ BÚ.
