A system for separation of non-magnetic metal particles in a mixture using an inclined rotating drum and the action of a travelling electromagnetic field. The mixture is introduced at the upper end of the inclined drum which is externally driven about its outer circumference in one direction. Simultaneously, a shifting electromagnetic field is generated along the lower part of the outer periphery of the drum in an opposite direction to rotation of the drum. The mixture as it travels through the drum is repeatedly moved upward in the direction of drum rotation along the inner wall due to frictional forces or in the direction of the shifting electromagnetic field. The successive raising and tumbling to the bottom of the drum provides complete stirring and promotes separation irrespective of particle size. The force of the electromagnetic field is not reduced by coverage with non-magnetic particles and a clear path exists since the interior of the drum is free of any obstructions.

System for non-magnetic metal selection

In a fuel cell comprising (1) a generator cell having a fuel gas (hydrogen gas) chamber, an oxidizing gas (oxygen gas) chamber and an electrolyzing solution chamber, (2) a fuel gas circulating circuit for supplying fuel gas to the fuel gas chamber of said generator cell, (3) an oxidizing gas circulating circuit for supplying the oxidizing gas to the oxidizing gas chamber of said generator cell, and (4) an electrolyte circulating circuit for supplying an electrolytic solution to said electrolyzing chamber, the improvement characterized in that a means for regulating the concentration of the electrolytic solution at a constant value is provided on said electrolyzing chamber and a means for removing the formed water from each of said gas chambers, a means for regulating simultaneously the gas pressures in both of said gas chambers, and a means for keeping constant the temperature of said electrolytic solution are provided on each of said gas chambers.
