Patent788,506, May 2, 1905. Application filed Nov. 16, invention relates especially to electrolytic cells in whicha fused electrolyte is employed at a comparatively high-currentdensity, and requires agitation or circulation for movingand circulating an intermediate electrode of liquid metal, suchas fused lead, in the production of caustic soda or metallicsodium. The inventor states that if a circular vessel contain-ing fused chloride of sodium be carrying a current which entersthe bath more or less centrally, and leaves its more or less. FIG. 3.—ASHCROFts apparatus. peripherally, as when a fused lead cathode and a carlion anodeare employed in the production of a sodium lead alloy orsodium amalgam from chloride of sodium, a common pot-electromagnet, having concentric poles, when placed concen-trically beneath the bath, will set up a violent swirl of thewhole contents of the bath. The necessary condition is, thatthe lines of magnetic force shall cut the lines of current—flow more or less at right angles to the direction of the re-quired motion. The direction of rotation of the fluid armaturewill be according to the relative directions of the magnetism andthe current flow.
