Abstract

25,808. Bone, W. A., Wilson, J. W. and MeCourt, C. D. Nov. 9. Atmospheric gas burners.- An explosive or self-burning mixture of two or more gases or vapours is burned just within the surface of a porous diaphragm, preferably made as described below. Fig. 1 shows a simple form of a unit, a number of which may be built up to form gas fires, grillers, toasters, &c., and, according to the Provisional Specification, also muffles, annealiug-furnaces, welding-appliances, and steam-generator furnaces, and also to heating an incandescent surface for lighting purposes. It consists of a porous diaphragm A secured in a casing C by a ring R. The mixture of gases is forced through the diaphragm and burns just under the surface E, which becomes incandescent. For grilling &c., two such diaphragms A are placed face to face. The diaphragms may be dome-shaped, cylindrical, &c., and their edges may be glazed to render them impervious. They are produced by burning a moulded mixture of fire-clay and rape seed, bran, plumbago, or other oxidizable material, or by consolidating and moulding a mass of granules of refractory material, such as burnt fire-clay containing a little finely-ground felspar, and then burning it.
