Abstract: 138,641. Arent, A. Feb. 5, 1919, [Convention date]. Varnishes.-Fibrous materials, such as wood, wood pulp, paper, canvas, duck, aeroplane cloth, &c., are fireproofed by treatment with a solution of a salt of an antimony-group metal, such as antimony trichloride, in an appropriate solvent, such as amyl acetate. Drying-oil, such as linseed oil, may be added to the solution when the canvas &c. is required to be waterproofed as well; or the metal salt may be dissolved in drying-oil alone. The metal salt deposit left on the canvas &c. is converted by the action of the air, or more readily by treatment with water, steam, or moist air, into insoluble fire-resistant basic or oxy-salts. Ordinary varnishes, such as solutions of natural or artificial gums or resins, or cellulose ester solutions, such as the acetate, nitrate, or viscose, or paints or stains comprising pigments or dyestuffs, may be made to give fire-resisting coatings by the addition of antimony trichloride &c., either alone or dissolved in amyl acetate or other solvent.

Abstract: A solid air-freshening product contains an active substance which is present in a gel formed from the metal soap with a gelling action and paraffin and which gradually evaporates from the gel. The metal soap acts in this case as the actual carrier material which does not evaporate. The paraffin, however, which has an evaporation number at 20 DEG C of from 8 to 1000, based on that of diethyl ether being 1, evaporates together with the evaporating active substance, especially an odour destroyer or a perfume or a mixture of these active substances, from the carrier material while substantially retaining the external appearance of the product and shrinkage of its volume. The product contains an amount of water which is sufficient for complete gelling of the metal soap with the paraffin. The metal soap preferably consists of sodium stearate. The product can contain an agent which lowers its solidification point, preferably a liquid glycol, e.g. 1,2-propylene glycol.
