a settling-space out of the path of travel of the intermingled pulp and mercury, and means to cause the passage of the pulp under pressure through said mixing-chamber, settling-chamber, and outlet-passage. (3.) In an amalgamator, the combination of a mixing-chamber having a pulp-inlet, mixing-means therein, a settling-chamber communicating with said mixing-chamber having a less restricted space than said mixing-chamber, and so located as to receive the intermingled pulp and mercury therefrom, said settling-chamber having a settling-space out of the path of travel of the intermingled pulp and mercury, and means for diluting the intermingled pulp and mercury during its passage through the amalgamator to aid the circulation of the same and the separation of the heavier from the lighter particles. (4.) In an amalgamator, the combination of a mixing-chamber having a pulp-inlet, means for intermingling the pulp and mercury therein, a settling-chamber having a less restricted space than the mixing-chamber in communication therewith, and adapted to receive the intermingled pulp and mercury therefrom, means in said settling-chamber for circulating and opening up said intermingled mass, a gangue-outlet therefrom, a settling-space therein out of the path of travel of the intermingled pulp and mercury, and a source of electricity connected with the interiors of said chambers to cause passage of the current through the intermingled pulp and mercury. (5.) An amalgamator, comprising distinct mixing and settling chambers in open communication, mixing-means in said mixing-chamber, said settling-chamber having less restricted space than said mixing-chamber, and having a settling-space out of the path of travel of the intermingled pulp and mercury, means for causing the pulp to circulate through said chambers under pressure, and means for diluting the pulp in its passage. (6.) In an amalgamator, a closed amalgamating-receptacle having inlet and outlet passages, and comprising a mixing-chamber with mixing-means therein, and a settling-chamber, of less restricted space than said mixing-chamber, with settling or freeing means therein, and having a settling space out of the path of travel of the intermingled pulp and mercury. (7.) In an amalgamator, an amalgamating-receptacle comprising a substantially horizontal mixing-chamber having mixing-means therein, communicating with a substantially horizontal stationary settling-chamber, of less restricted space than said mixing-chamber, having settling-means therein and a settling-space out of the path of travel of the intermingled pulp and mercury. (8.) An amalgamator comprising a mixing-chamber, a settling-chamber having a less restricted space than said mixing-chamber leading therefrom, and vehicle fluid inlet-passage near the initial end of said settling-chamber, said settling chamber having a settling-space outside the path of travel of the intermingled pulp and mercury. (9.) The described method for amalgamating metals, which consists in producing a pulp, bringing the same into contact with mercury, enforcing and intermingling of the mercury and the pulp, confining the mixed pulp and mercury within a restricted space during such intermingling, thereafter freeing the intermingled pulp and mercury from said restricted space, separating the heavier particles from the lighter by gravitation in a space less restricted for the circulation of the pulp-particles, and preventing further intermingling. (10.) The described method for amalgamating metals, which consists in producing a pulp, filling a space with said pulp and with mercury in the presence of pressure, and enforcing an intermingling of the two, placing said filled space in communication with a second space, and permitting the latter to be filled with the intermingled pulp and mercury from the first, also in the presence of pressure, freeing the mixture in said second space from the mixture-enforcing action of the first space, settling the amalgam and mercury in said second space, and carrying off the lighter sand and gangue under the pressure therein. (11.) The described method for amalgamating metals which consists in producing a pulp, bringing the same into contact with mercury, enforcing an intermingling of the mercury and the pulp, confining the mixed pulp and mercury within a restricted space during such intermingling, freeing the intermingled pulp and mercury from said restricted space, diluting the same with liquid, separating the heavier particles from the lighter, and settling the same by gravitation, and preventing the reintermingling of the settled particles. (12.) The described method for amalgamating metals, which consists in producing a pulp, introducing the same into a space containing mercury, said space being such that a slight movement of the pulp-particles in certain directions results in contact with the mercury, causing such movement of the pulp as to enforce an intermingling of the same with the mercury, passing the mixed pulp and mercury into a space such that the pulp-particles may move with relative freedom without contact with mercury, opening up the material of the mixture by disturbing the same while in this space, permitting the separation of the heavier particles therefrom by gravitation, and preventing further intermingling. (13.) The process of amalgamating metals which consists in forming a pulp, bringing the same into contact with mercury, enforcing an intermingling of the mercury and the pulp, confining the mixed pulp and mercury within a restricted space during such intermingling, thereafter freeing the mixed pulp and mercury from said restricted space, separating the heavier particles by gravitation in a less restricted space, and causing the passage of an electric current through the intermingled pulp and mercury. (14.) The described method for amalgamating metals which consists in producing a pulp, passing the same through a confined space containing mercury, enforcing an intermingling of the mercury and the pulp therein, passing the intermingled mercury and pulp through a less restricted space, separating therein the heavier particles from the lighter by gravitation, settling the same out of the path of the moving mass, and preventing further intermingling of the settled particles. (15.) The described method of amalgamating metals which consists in producing a pulp, passing the same through a confined space containing mercury, intermingling the mercury and the pulp therein, causing the intermingled mass to travel in a substantially horizontal direction through a less restricted space, opening up the materials thereof during its passage through said less restricted space, and separating the heavier particles from the lighter by gravitation. (16.) The described method for amalgamating metals which consists in producing a pulp, bringing the same into contact with mercury, enforcing an intermingling of the mercury and pulp, confining the mixed pulp and mercury within a restricted space during such intermingling, causing the intermingled mass to travel in a substantially horizontal direction through a less restricted space, diluting the same with liquid, separating the heavier particles from the lighter by gravitation, and preventing the reintermingling of the settled particles.

No. 15230.—7th August, 1902.—JOHN WILLIAM PORTER, of the Rifle Ranges, Williamstown, Victoria, Ranger. Improved apparatus for operating moving targets.*

Claims.—(1.) Improved apparatus for operating moving targets, comprising a traveller running on rails and carrying a rotatable target adapted to be rotated at irregular intervals through an angle of 90° so as to turn same “edge on” and “face on” alternately, and means for retaining same in either position, substantially as specified and illustrated. (2.)
