Abstract
921,719. Magnetic stirrers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 1, 1961 [May 6, 1960], No. 16079/60. Class 86. A stirrer for liquids comprises a cone or dynamically equivalent shape of magnetic material lying on the bottom of the container and caused to roll by a rotating magnetic field. As shown, the stirrer comprises a disc 2 having on the underside a coaxial hemisphere 3 (corresponding to a cone of which the disc 2 is the base and the point 11 the apex). The stirrer may have vanes as at 12, and may alternatively be a pure cone as at 10 or a diso with a central pin. The stirrer may be encased in polythene. The rotating field is generated by a U-shaped salient pole magnet which rotates about an axis 9 passing through one of the poles 7 and which may be balanced by a weight 17. It may be permanent or D.C. energized and may be bar-shaped. Alternatively, the rotating field may be generated by a fixed multipolar field winding energized by a polyphase A.C. supply.
