no albert PI Steb beus of little boock ck al arkansas ore concentrating agitator tor the agitator t casing e A is suitably supported on framework BB CC the casing forms an at agitating chamber A enlarged at or near its central portion to permit a proper circulation of air air cut currents rents therein prior to their passage into tile the exist pipe a the exit pipe a extends through the casing basing A and well into the agitating chamber this is for the S A A U E K C NO purpose of preventing a direct passage of the air currents from inlet eto and through the exit pipe a near the side of the casing casier A is a feed hopper D which communicates S with the chamber A by means of a feed conduit d in which works a feeding device below the feeding device and preferably in the side aide of the casing opposite thereto is the air inlet pipe b communicating by suitable irinec 1 eions I 1 W with any usual al source of air blast the lower part of the casing A terminates in a red reduced portion A az 2 extending exten extending din 0 some som distance below the agitating chamber A the bottom is ia closed in a wall az having several slots aa therein and below the said bottom is the chute as ae terminating in a discharge spout aa extending upward from the bottom wall aa is the stud or pin ua u upon which the shaft aio is supported and carries Cs it at its lower part the throwing blades ae aa at one side of the reduced portion AZ a sliding I 1 door is provided I 1 at k which permits access to the interior of the reduced portion in opposite walls walla of the casing I 1 A are the observation windows L through r which the operator can view the internal workings of the machine and re regulate the feed of material thereto accordingly the operations is as follows the finely ground or powdered ore is fed into the hol hopper D and transmitted to the agitating chamber bv the feed screw As it falls the all air blast passes through it carrying away some of the lighter particles through the exit pipe a As the mass falls it is acted on by the throwing blades which separate and scatter the mass and throw v it upward where the blast acts to carev curry it into and through the exit pipe T it 0 a i r blast enteria entering the agitator ari does not pass direct to the exit pipe a but circulates around in curre currents lItS partly due to tile the fact that the air blast enters the chamber at an all ano anole angle ang le to the exit and that the exit pipe ex teals well into the agitating chamber the circulation cu lation of these currents affords opportunity for the heavier particle articles to fall and some borne of them thein pass out through the slots in the bottom of the reduced portion aa A 2 of the agitator ta tor while others with the light material are carried into the settling chamber S where the heavy and valuable portions of the mass entering the setti settling ing chamber fall owin owing 11 to the reduced air currents ur and are conducted out of the machine by the chute 13 no j leo horwitz horwit of berlin germany electric lamp for miners use this invention relates toan to an elect electric lc switching ing device for two

done the fuel is first transformed in a separate e furnace into combustible co ln bastible bus tible gas gam ind and then forcel forced in association with hot air into the crucible of the furnace fur

center of a submerged horizontally disposed slowly rotating surface at the periphery of which a soft bank of sand hand or other suitable suitable material is maintained for the pur purpose pose of arresting heavier matter the conglomerate fed into the center of this surface is rotated at a speed sufficient only to develop centrifugal force sligh slightly try in exec excess of that necessary to overcome the inertia of the heavier material resting on the support and is ay suh material is slowly driven from froin the center to tile the periphery or of the surface it is kept in a prolonged disintegrating action of the comparatively still water whereby the lighter and heavier materials ire are effectively separated from each other the li lighter ahter beto being gently g lifted and

with a suitable solvent and a centrally located tube arrall arranged ged in said tank containing an all agitator through tile the operation of which the ore pul pulp parida and a suitable solvent may be conveyed from the main portion of the tank into and up through the centrally located tube in such a manner that the solvent falls slowly in the main portion of the tank and rises rapidly in the central tube th fit practical use of this apparatus the ore pulp or ground ore is deposited with solvent into the corn compartment apartment part ment 2 21 and motion is im parted to the shaft 7 which causes rot rotation aaion of the cups 21 and 23 and the wings 11 ate thereof thereby causing said parts to act as a pump or agitator within the tube 3 and the solvent which has entered the tube 3 1 from tile the cot compartment a r ent 2 abrou through h the openings ps 20 is raised by centrifugal action within the tube this causes a suction through the openings 20 from the compartment 2 by which the ore pulp pull in said compartment are drawn into the lower end of the tube and upwardly through the space between the wings 22 and elevated to the open upper end of said tube from which they again pass into the compartment 2 tile the ore pulp and solvent descend by gravitation in the compartment 2 and are again taken up into the tube as before and elevated there through this action goin on OD
