Abstract

1,055,312. Electromagnetic switches. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 5, 1964 [Feb. 20, 1963], No. 6845/63. Heading H2B. [Also in Division G4] Switching means serving as an indicator or storage device comprises two or more liquid cavities interconnected serially through constricted passages, a globule of an electrically conducting liquid, e.g. mercury or molten metal, in one of the cavities, at least two electrodes in each cavity between which electrodes a current path can be established through the globule if it is in that cavity so that the current through the globule in the presence of an external magnetic field causes the globule to transfer to the next cavity. A two-cavity device, Fig. 1, having a cross-section as shown in Fig. 2 includes a ball of mercury in a cavity A which is transferred to the cavity B on the occurrence of a current or pulse I through electrodes 21, and returned by a current or pulse I 2 between electrodes 22. Small channels 17 in the walls of the cavities allow an inert gas enclosed with the mercury to pass freely. Alternatively the device may be evacuated.
