Abstract

831,155. Magnetic relays; mercury and other conducting liquid switches. KOHLSTROM, C. April 11, 1957, No. 11898/57. Class 38 (5). [Also in Group XXXV] A magnetically-actuated relay or operating device has a movable member consisting of a liquid alloy of mercury and a ferromagnetic material such as iron. As shown in Fig. 1 a body 1 of the material is moved on energization of the coil 3 to connect terminals 7, 8. In Fig. 2 the flow of the alloy 9 under the influence of the coil 11 is controlled by an adjustable screw 15. A device responsive to current surges is shown in Fig. 3, each surge moving the alloy 19 to the other end of a tube 20 where it remains until the next surge. Permanent magnets may be used instead of the energizing coils.
