Extract from Specification.—The essential feature of novelty in the improved machine consists in the combination of two monoplanes arranged one behind the other upon a single frame of triangular cross-section and each of which planes is provided with its own means of propulsion. Other features of the construction consist in the combination with each of such planes of a small plane arranged below it and secured transversely across the base of the frame, and to the combination with each of the main planes of flexibly hinged extensions that normally incline rearwards from the back edge of the plane.

No. 27097.—29th December, 1909.—HENRY HOWARD GREENWAY, Metallurgist, of 62 London Wall, London E.C.; HENRY LIVINGSTONE SULMAN, Metallurgist, of 44 London Wall, London E.C.; and ARTHUR HOWARD HIGGINS, Metallurgist, of Broken Hill, New South Wales, Australia. Improvements in or relating to the concentration of ores.

Extract from Specification.—The crushed ore is mixed with water containing in solution a small percentage of a mineral-frothing agent—that is, of one or more organic substances which enable metallic sulphides to float under conditions hereinafter specified—and containing also a small percentage of a suitable acid, such as sulphuric acid, and the mixture is thoroughly agitated. The ore-particles are caused to come into contact with a gas such as air; thus a gas may be liberated in, generated in, or effectively introduced into the mixture so that the ore-particles come into contact with the gas, and the result is that metallic sulphide particles float to the surface in the form of a froth or scum and can thereafter be separated by any well-known means. Among the organic substances which, in solution, we have found suitable for use as mineral-frothing agents with certain ores are alcohols, such as methyl-, propyl-, ethyl-, butyl-, or amyl-alcohol or mixtures of these; organic acids—viz., acetic acid, propionic acid, butyric acid, and valerianic and lactic acid; ethereal salts, such as ethyl acetate, amyl acetate; aromatic hydroxy compounds—viz., phenol, cresol, and their homologues and many of their derivatives, such as resorcin, trinitrophenol, salicylic acid; ketones, such as acetone or camphor; aldehydes, such as formaldehyde and furfural, or mixtures of these.

In an electric valve, the combination of a conductor body and a warm wire. (3.) In an electric valve, the combination of a conductor body, a wire, and means for heating the said wire. (4.)
