No. 16299.—6th May, 1903.—PETER BURD JAGGER, of 5, Warrington Gardens, Maida Vale, London, England. Improvements in non-refillable bottles and like vessels.

Claims.—(1.) The improved bottle or vessel for containing liquid, and the means for preventing the same, when once emptied, from being refilled in fraud of the original packer, substantially as described and shown. (2.) The improved non-refillable bottle or vessel a for containing liquid, a seating b formed in the neck or shoulder of the said vessel, with a ball-valve c adapted to fit on to the said seating b, and surmounted by a coned stopper f having a concave base resting upon the ball-stopper c, a frame or cage surmounting the said coned stopper f, the base ring h of which rests upon an annular ridge d formed in the neck of the vessel a, the said base ring being formed integrally or otherwise with two or more uprights k k connected to a crown ring l and a central table or partition m, the said crown ring being adapted for expansion radially to fit into an annular groove e formed in the neck of the vessel a, the said frame or cage, when in position, being surmounted by a cork or stopper p, substantially as and for the purposes set forth, and shown by the drawings. (3.) The improved non-refillable bottle or vessel a for containing liquids, a seating b formed in the neck or shoulder of said vessel, a ball-valve c adapted to fit on to the said seating b, and surmounted by a coned stopper f having a concave base resting upon the ball-stopper c, a frame or cage surmounting the said stopper f, the base ring h whereof rests upon an annular ridge d formed in the neck of the vessel a, the said base ring being formed integrally or otherwise with uprights k k connected to a crown ring l and a central table or partition m, the said crown ring being adapted for expansion radially to fit into an annular groove t formed in the neck of the vessel a, the said frame or cage, when in position, being surmounted by a cork or stopper p, substantially as and for the purposes described, and shown by the drawings, more particularly by Figs. 10 and 11. (4.) In a non-refillable bottle or like vessel a having any form of valve or stopper for closing the neck of said vessel, the combination therewith of a metallic cage or frame the upper end or crown ring of which is adapted for expansion radially to fit into an annular groove formed in the neck of said vessel, substantially as described and shown. (5.) In a non-refillable prepared bottle or vessel such as a, the combination therewith of a ball-valve c, coned stopper f, and metallic frame such as h, k, l, m, substantially as set forth and shown.

No. 16300.—6th May, 1903.—EDWARD HALL MILLER, of 81, Chardmore Road, Clapton Common, London, England, Fellow of the Chemical Society. A process for the elimination of sulphur from sulphide-ores.

Claims.—(1.) The described process for the elimination of sulphur from sulphide-ores, consisting in mixing powdered ore with powdered carbon or carbonaceous material and with sodium-sulphide or other suitable sulphide, exposing the mixture to a low heat in a restricted current of air for a short time, exposing the still heated product freely to air to cause rapid oxidation to ensue, and mixing the resultant product with a nitrate, such as Chili saltpetre, and heating the mixture. (2.) The process of completing the elimination of sulphur from sulphide-ores, consisting in heating the ore from which most of the sulphur has been eliminated with Chili saltpetre or other suitable nitrate, as described.
(Specification, 4s. 3d.)

No. 16302.—6th May, 1903.—THOMAS JOHNSTON GRIER, of Lead, in the County of Lawrence, South Dakota, United States of America, Superintendent of Homestake Mining Company. Improvements in processes for recovering precious metals from ores.

Claims.—(1.) The process of extracting precious metals from slimes, consisting in subjecting slimes to the action of a cyanide solution whereby the watery portions of the slimes may be replaced by the cyanide solution, the latter being of greater density than the water of the slimes, then treating the charge with compressed air and afterwards replacing the cyanide solution with a salt solution of greater density than the cyanide solution, as set forth. (2.) The process of extracting precious metals from slimes, consisting in subjecting the slimes to the action of a cyanide solution under pressure, whereby the water portions of the slimes may be replaced by the cyanide solution, the latter being of greater density than the water of the slimes, then treating the charge with compressed air and afterwards replacing the cyanide solution by introducing a salt solution under pressure and of greater density than the cyanide solution, as set forth. (3.) The process of extracting precious metals from slimes, consisting in spraying the thick slimes with a protective solution to neutralise the acids therein, of introducing a cyanide-of-potassium solution in the slimes to replace the watery portions thereof, the latter being of less density than the cyanide solution, afterwards treating the charge with air under pressure and then introducing in the vat containing the solution a salt solution under pressure, as set forth. (4.) The process of extracting precious metals from slimes, consisting in subjecting the slimes to a protective solution to neutralise the acid therein, then introducing a cyanide-potassium solution into the slimes to replace the watery portion thereof, the latter being of less density than the cyanide solution, of treating the charge with compressed air and afterward introducing in the vat in which the slime is contained a salt solution, and heating the contents of the vat above its false bottom for the purpose of reducing the density of the upper stratum of liquid, as set forth. (5.) The process of extracting precious metals from slimes, consisting in directing the slimes into a settling-tank, drawing off the thicker portions of the slimes and depositing the same into a leaching-vat, of introducing a cyanide solution under pressure through perforations in the false bottom of the vat, causing the watery portions of the slimes to be replaced by said cyanide solution, then treating the charge with air under pressure and afterward introducing in the vat a salt solution of greater density than the cyanide solution, as set forth.
