  • Nontoxic low melting point fusible alloy lubrication of electromagnetic railgun armatures and rails
    Patent number: 8653013
    Abstract: A railgun which has a conductive lubricant and system of delivery reduces the electrical resistance and friction of the armature-rail sliding contact, thereby decreasing the amount of heat generated at the electrical contact. The conductive lubricant may be a ternary alloy of bismuth, indium and tin. The system of delivery for the conductive lubricant may include a plurality of surface reservoirs formed in either the rail surface, the armature face, or both.
    Type: Grant
    Filed: September 20, 2011
    Date of Patent: February 18, 2014
    Assignee: The United States of America as represented by the Secretary of the Navy

  • Mercury-free fusible alloy for electrolyzing salts
    Publication number: 20130319876
    Abstract: An apparatus and method is provided for the production of alkali metals and caustic solutions. The apparatus and method do not require the use of toxic liquid mercury-sodium amalgam electrodes. The apparatus and methods utilize a bismuth-indium-tin eutectic alloy as a substitute for the mercury electrode used in a conventional Castner-Kellner apparatus.
