  • Metal alloy and method of preparation thereof
    Patent number: 5156806
    Abstract: Ternary metallic alloys of the formula Li.sub.x B.sub.y Mg.sub.z wherein 5.ltoreq.x.ltoreq.0.90, 0.05.ltoreq.y.ltoreq.0.90, 0.05.ltoreq.z.ltoreq.0.90, and x+y+z=1 and a method of preparing them. These alloys find use in areas where superlight weight, high specific strength (strength/weight ratio) and oxidation resistance are required.
    Type: Grant
    Filed: May 5, 1975
    Date of Patent: October 20, 1992
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Raymond A. Sutula, Frederick E. Wang
  • Pyrophoric alloy complexes
    Patent number: 4960564
    Abstract: Alloy complexes which are composed of (1) lithium (Li, (2) Boron (B), and ) one or more of the following elements: sodium (Na), potassium (K), rubidium (Rb), and cesium (Ce). These alloy complexes in powder form react spontaneously with air upon contact to produce large amounts of heat.
    Type: Grant
    Filed: April 6, 1978
    Date of Patent: October 2, 1990
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Raymond A. Sutula, Frederick E. Wang
  • Lightweight battery electrode
    Patent number: 4215190
    Abstract: An electrode grid comprising a sintered mat or felt of graphite fibers which are coated with a mixture of from about 85 to less than 100 weight percent of nickel and from more than zero to about 15 weight percent of phosphorous, the graphite fibers having a density greater than 1.8 gm/cm.sup.3. The grid is attached to an electrical connector and then impregnated with an active material such as nickel hydroxide or cadmium hydroxide to form an electrode.
    Type: Grant

    Inventors: William A. Ferrando, Raymond A. Sutula
  • Battery with boron-lithium alloy anode
    Patent number: 4162352
    Abstract: A new anode material consisting essentially of from about 50 weight percent o about 90 weight percent of lithium and from about 50 weight percent to about 10 weight percent of boron, and current generating electrochemical cells utilizing said anode material.
    Type: Grant
    Filed: September 24, 1976
    Date of Patent: July 24, 1979
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Raymond A. Sutula, Frederick E. Wang
  • Battery electrolyte
    Patent number: 4026725
    Abstract: A method of activating a battery containing an alkali metal halide electrte comprising placing a powdered alkali metal carbide selected from the group consisting of lithium carbide, sodium carbide, potassium carbide, rubidium carbide, cesium carbide, and mixtures thereof into contact with the alkali metal halide electrolyte and then contacting the powdered alkali metal carbide with a halogen gas selected from the group consisting of fluorine, chlorine, and mixtures thereof.
