tenth, to provide an electro-chemical process for the extraction of the metallic values of ores, in which ores are reduced to ore-pulp and are formed into a chemical ore-pulp solution, which is kept in continuous movement for a predetermined period of time in fixed charges, and is distributed in a continuously moving thin sheet in contact with the atmosphere, and in which the continuously moving ore-pulp is brought in contact with suitable electrolytic electrodes that are adapted to collect the metallic values in the chemical ore-pulp solutions; eleventh, to provide a process in which the ores are first pulverised in cyanide-solutions or other chemical solutions, to start and establish a chemical action that will prepare the ore-pulp for the electrical precipitation of its metals in subsequent treatment, then to amalgamate said ore-pulp, then to settle and classify and to chemically treat said ore-pulp to destroy any acid salts present therein detrimental to the solvent action of cyanide or other chemical solutions, then to separate the clear cyanide or other chemical solutions from the ore-pulp and return it to the ore recrushing and pulverising machinery’s solution supply-tank, then to mix said ore-pulp in fixed charges with restrengthened cyanide or any other suitable chemical or chemicals or with cyanide and other chemicals, then to heat said chemical ore-pulp solution, then to agitate by moving said chemical ore-pulp solutions in a continuous stream for a predetermined period of time and at the same time to aerate by distributing said continuous-moving chemical ore-pulp solution in a thin stream in contact with the atmosphere, then at the same time flowing said chemical ore-pulp solution in contact with suitable electrolytic electrodes until they have collected a satisfactory percentage of the said chemical ore-pulp solution’s metallic values, then settling and decanting or separating the chemical solutions from the ore-pulp, and then conveying the said chemical solutions to the recrushing and pulverising machinery’s chemical solution supply-tank, and then running the settled ore-pulp to waste or to further treatment as desired; twelfth, to provide a process in which the ores are first pulverised in cyanide-solutions or other chemical solutions or in cyanide and other chemical solutions, to start and establish a chemical action that will facilitate the recovery of the free particles of the minerals in the ore-pulp by amalgamation and that will prepare the chemical ore-pulp solution for the electrical precipitation of its metals in subsequent treatment, then to amalgamate said ore-pulp solution, then to settle and classify and to chemically treat said ore-pulp solution to destroy any acid salts present therein detrimental to the solvent action of cyanide or other chemical solutions, then to separate the clear cyanide or other chemical solutions from the ore-pulp and return it to the ore recrushing and pulverising machinery’s chemical-solution supply-tank, then to mix said ore-pulp in fixed charges with restrengthened cyanide or other chemical solutions or with cyanide and other chemical solutions, then to heat said fixed charges, then to agitate said chemical ore-pulp solutions by moving them in a continuous stream for about from two hours’ to about twelve hours’ time and at the same time to aerate by distributing said continuous-moving chemical ore-pulp solutions in a thin conical-shaped stream in contact with the atmosphere, then at the same time flowing said chemical ore-pulp solutions in contact with suitable electrolytic electrodes until they have collected all they can collect of the said chemical ore-pulp solution’s metallic values, then settling and decanting or separating the chemical solutions from the ore-pulp, and then conveying the said chemical solutions to the recrushing and pulverising machinery’s chemical-solution supply-tank, and then concentrating the settled ore-pulp.

No. 19222.—20th March, 1905.—WILBUR ALSON HENDRYX, of Hotel Angeles, corner of Fourth and Spring Streets, Los Angeles, California, United States of America, Physician and Surgeon. An apparatus for extracting metals from their ores and solutions, and for agitating purposes.

Extract from Specification.—My invention relates to an apparatus for extracting metals from their ores and from solutions, and for agitating purposes, and the objects of my invention are: First, to provide an apparatus in which crushed or ground or pulverised ores may be treated in solutions for the extraction of their values; second, to provide an apparatus in which crushed or ground or pulverised ores may be treated in cyanide-solutions; third, to provide an apparatus in which crushed, ground, or pulverised ores may be treated in chemical solutions, and in which the ore-pulp and chemical solutions are in constant, continuous, and progressive agitation; fourth, to provide an apparatus in which crushed, ground, or pulverised ores may be treated in chemical solutions and be agitated, and also be continuously and progressively aerated; fifth, to provide an apparatus in

which crushed or ground or pulverised ores may be treated, and their values recovered by electrolytic deposition; sixth, to provide an apparatus in which crushed or ground or pulverised ores and slimes may be continuously and progressively agitated and aerated, and their values extracted by chemical solutions or electrical precipitation; seventh, to provide an apparatus in which fluid, either by itself or mingled with other substances, may be agitated by upward or downward movement; eighth, to provide a cyaniding apparatus by means of which crushed, ground, or pulverised ores may be treated in cyanide-solutions and be continuously, progressively, and evenly agitated, and be continuously and progressively and evenly charged with all the oxygen it is capable of absorbing from the commencement of its treatment until its values have been extracted; ninth, to provide an apparatus for the treatment of crushed or ground or pulverised ores by suitable hot chemical solutions; tenth, to provide an ore-treating tank and apparatus, in which ore-pulp solutions may be agitated by positive and continuous upward-and-downward movement of the ore-pulp solutions; eleventh, to provide an ore-treating tank and apparatus, in which ore-pulp solutions and cyanide or other solutions are aerated by direct contact with the atmosphere; twelfth, to provide an ore-treating apparatus in which the refractory metallic compounds and the volatile elements of ores are broken up, separated, and decomposed, and their values extracted and removed by positive vertical reciprocal movement and agitation, oxidization, or aeration of the pulp, combined with the use of cyanide or other chemical solutions and electrolytic deposition, and to regenerate the chemicals and prevent the fouling of the solution.

No. 19258.—25th March, 1905.—ALBERT BERRY PROUD, Jeweller, and HUGH MCDONALD ALEXANDER, Patternmaker, both of Dunedin, New Zealand. Improvements in fixing hat-pins.

Extract from Specification.—In our invention each pin is furnished with a plate or loose boss having a central hole in which the pin slides. The pin is enlarged near its point so that it cannot be completely withdrawn; but it can be sufficiently withdrawn for convenience. This plate or boss is secured to the proper place at the side of a hat as required.

No. 19265.—30th March, 1905.—ALFRED SPAULDING PATTERSON, of Nos. 570–576, Bourke Street, Melbourne, Victoria, Australia, General Manager for the Massey-Harris Company, Limited (nominee of Massey-Harris Company, Limited, a company duly incorporated under the Joint-stock Companies Act of the Dominion of Canada, of 915, King Street West, Toronto, Ontario, Canada, Manufacturers, the assignees of Charles H. Hackett and Thomas W. Morgan, both of Waterloo, Iowa, United States of America). Improvements in centrifugal liquid-separators.

Extract from Specification.—The invention relates to improvements in centrifugal liquid-separators, and the objects of the invention are—(1) to so construct such liners as have concentric layers of separating-discs in inner and outer series as to secure more perfect action by increasing the resistance offered to the passage of the liquid over them; (2) to devise an elastic collar bearing for the shaft of the bowl which will be sufficiently elastic to be responsive to the sidewise thrust of the shaft, and which will automatically readjust itself to its true central position when the sidewise pressure upon it has been removed. These objects are attained (1) by spacing the outer discs of the liner closer together than the inner
