———

Claims.—(1.) In the treatment of pulverous substances, as in the production of artificial fuel in the form of balls, briquettes, or the like, the method which consists in thoroughly mixing the ingredients in a dry cold state, heating the mixture in a fluid-heated chamber whilst still dry, and then whilst agitating the mixture injecting live steam there-into so as to moisten the same, substantially as described.

[NOTE.—Here follow four other claims.]

No. 28565.—11th October, 1910.—DOUGLAS GRIFFITHS, of 5 Josephine Avenue, Brixton, London, England, Clerk, and WALTER ROY WILTHEW, of Woodstock House, James Street and Oxford Street, London aforesaid, Brewer. Improvements in apparatus for delivering measured quantities of liquor.

———

Extract from Specification.—The arrangement is such that the operation of the evacuation of the contents of the measuring-vessel has the effect of emptying of liquor a portion of the passage through which air rises into the bottle or other vessel, and substitutes air for the liquor in that portion, so that when the measuring-chamber is again placed in communication with the bottle or other vessel the pressure in the downward-flow passage for the liquor will predominate, and the refilling will commence promptly and take place rapidly.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 28572.—11th October, 1910.—CLANCY METALS PROCESS COMPANY, a corporation of the State of New York, of No. 170 Broadway, New York, Borough of Manhattan, United States of America, engaged in the business of treating ores (assignees of John Collins Clancy, of No. 909 St. Mark’s Avenue, New York, United States of America, Chemist). Treatment of precious metalliferous ores.

———

Claims.—(1.) The process of treating ore containing precious metals which consists in subjecting said ore to the action of a solution containing a cyanogen-bearing material and an amidine or amide compound, and electrolyzing said solution or mixture. (2.) The process of treating ore containing precious metals which consists in subjecting said ore to the action of a solution containing a cyanamide, and electrolyzing the said solution or mixture. (3.) The process of treating ore containing precious metals which consists in subjecting said ore to the action of a solution containing a cyanamide in the presence of a halogen compound, and electrolyzing said solution or mixture. (4.) The process of treating ore containing precious metals which consists in subjecting said ore to the action of a cyanogen-bearing solution containing a cyanamide, and electrolyzing said solution or mixture. (5.) The process of treating ore containing precious metals which consists in subjecting said ore to the action of a cyanogen-bearing solution containing a soluble cyanamide and a halogen compound, and electrolyzing said solution or mixture. (6.) The process of regenerating cyanogen-bearing solutions which consists in subjecting the said solutions to the action of a soluble amidine or amide compound (such, for example, as calcium cyanamide), and electrolyzing the said solutions. (7.) The process of treating ore containing precious metals which consists in subjecting the ore to the action of a thiocyanate and a soluble halogen compound, and oxidizing the mixture. (8.) The process of treating ores containing precious metals which consists in subjecting the ore to the action of a soluble thiocyanate and a halogen compound, and oxidizing said mixture by means of ozone. (9.) The process of treating ore containing precious metals which consists in subjecting the ores to a solution containing thiocyanate and a halogen compound, and electrolyzing the mixture. (10.) The process of treating sulphide ore containing precious metals which consists in subjecting the said ore to the action of an alkaline cyanogen-bearing solution in presence of oxygen until a part or all of the cyanide has been transformed into a non-available sulpho-cyanide compound, or other non-available cyanide compounds, then subjecting the said solution or mixture to electrolysis.
