No. 13457.—7th March, 1901.—JOSEPH HENRY LANCASHIRE, of 64, Barrow Road, Streatham Common, London, England, Engineer, and JAMES WESTHEAD WORSEY, of 137, Boundary Road, St. Helens, Lancaster, England, Chemist. Improvements in treating complex ores.*

Claims.—(1.) The treatment of complex ores containing zinc and lead, with or without other metals, and also sulphur, for the separation and extraction of their metallic contents, substantially as set forth. (2.) In the treatment of refractory sulphide ores containing lead and zinc, treating the comminuted and calcined ore in a watertight receptacle with dilute sulphuric acid, adding solid nitrate of soda before or during the reaction, roasting the product with or without an oxidant, dissolving out the soluble salts, and separating and volatilising the zinc in the form of oxide, substantially as set forth. (3.) In the treatment of refractory sulphide ores as set forth above, adding to the charge in the roaster a further quantity of nitrate of soda, with or without quicklime, for the purpose of oxidizing any iron present in the ferrous state. (4.)

No. 13854.—26th July, 1901.—JARIG PHILIPPUS VAN DER PLOEG, Civil Engineer, retired from the Government Service of the Public Works Department in the Netherlands, East Indies, of 8, Bezuidenhout, The Hague, Holland. Improvements for treatment of ores and materials containing antimony.

Claims.—(1.) Process for the complete separation of antimony from substances of all kinds containing the same, in particular from ores wherein the finely divided materials containing antimony, or ores, are mixed with pulverised quicklime, or are ground up together with the same and are then mixed with water either before or after the addition of mono- or poly-sulphides of calcium or magnesium, for the purpose of bringing alone the antimony into solution by converting it into the form of easily soluble low double sulphides best suited for electrolysis, without the employment of artificial heat or pressure. (2.) In combination with the process referred to in claim 1, the method of separating the antimony from the solutions obtained thereby, either in the metallic form by means of electrolysis, or as sulphide, or in the form of any other antimony compound. (3.) In combination with the process referred to in claims 1 and 2, the method of repeatedly using the said sulphide solutions after separation of the antimony by electrolysis, as solvent, for new quantities of fresh ores or of ores that have been already treated, either with or without addition of fresh quicklime and calcium or magnesium-sulphides, according to the nature of the antimony compounds, for the purpose of completely extracting the antimony.

No. 13994. — 12th September, 1901. — JOHN PERCY GOODBUN, formerly of Ararat, Victoria, but at present of the Badminton Club, Piccadilly, London, England, Gentleman. An improved “dumb-caddie” or golf-club-bag support.

Claims.—(1.) In a support for golf-club bags, the combination of a stick or rod, a cross-piece pivoted to the bottom end thereof, means for securing the cross-piece at right angles to the stick or rod, and means for attaching the stick or rod to the mouth of a golf-club bag, substantially as set forth. (2.) In a support for golf-club bags, the combination of a stick or support, a cross-piece pivoted thereto, means for securing the cross-piece at right angles to the stick, and a strap attached to the stick by means of which the stick may be connected to a golf-club bag, substantially as shown and described. (3.) In a support for golf-club bags, the combination of a stick or rod, a cross-piece pivoted thereto, chains or cords attached to the cross-piece, a ring to which such chains or cords are connected, a spring catch to secure the ring in its operative position, and a strap attached to the stick by means of which the stick may be connected to the mouth of a golf-club bag, substantially as shown and described. (4.) In a support for golf-club bags, the combination of a stick or rod, a cross-piece pivoted thereto, means for securing the cross-piece at right angles to the stick or rod, means for attaching the stick or rod to the mouth of a golf-club bag, and a second stick or rod flexibly attached to the main stick, substantially as set forth. (5.) In a support for golf-club bags, the combination of a stick or rod, a cross-piece pivoted thereto, means for securing the cross-piece at right angles to the stick or rod, a loop fixed to the stick or rod and a loop sliding on the same, a strap carried by such fixed and sliding loops, and hooks or catches attached to the strap by means of which the support may be attached to a golf-club bag, substantially as shown and described.

No. 14073.—28th September, 1901.—ALFRED BRAKE, of 80, Abbeyville Road, Clapham, London, England, Aerated-water Manufacturer. Improvements in apparatus for drawing off liquids.

Extract from Specification.—In the specification of former Letters Patent granted to me, dated the 28th March, 1901, No. 13506, I have described constructions of apparatus for drawing off liquids, according to which the liquid is drawn off through an intermediate vessel which is normally in communication with the main liquid-storing vessel and which, for the purpose of drawing off, is first placed in communication with the external atmosphere, after which the outlet of the intermediate vessel is opened and in some cases the inlet of the intermediate vessel is simultaneously or almost simultaneously closed, the communication between the upper part of the intermediate vessel and the atmosphere being maintained opened during the drawing-off so as to allow the liquid to flow off gently. Now the present invention has reference, inter alia, to various modified constructions and arrangements of apparatus of the kind above referred to for drawing off liquid, some of which are specially adapted for drawing off aerated liquid, such as soda-water, that is under considerable pressure; others are better adapted for drawing off liquid, such as lager and like frothy beer, that is under a moderate pressure, whilst one is adapted for drawing off in a more accurate manner than heretofore measured quantities of liquid from a closed vessel in which a partial vacuum is maintained.
[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the descriptive part of the specification is inserted instead.]
