  • Gas and process for plasma arc cutting
    Patent number: 4611109
    Abstract: There is proposed as a plasma-producing gas, a gas containing the elements nitrogen and oxygen chemically combined in a nitrogen oxide and in particular nitrous oxide. These plasma-producing gases or mixture of gases stored in a bottle, a frame, a container, a tank, in the gaseous or liquid form at ambient or cryogenic temperature, are applicable to the plasma arc cutting of electrically conductive materials.
    Type: Grant

    Inventors: Maurice Bruni, George Duboz
  • Stable ternary cryogenic fuel having density in the gaseous state less than that of air
    Patent number: 4426207
    Abstract: A stable cryogenic fuel mixture containing 25 to 30% by volume of acetylene, 61 to 72% by volume of ethylene and 3 to 9% by volume of a C.sub.3 hydrocarbon preferably propylene. This fuel mixture having a density in the gaseous state, which is less than the density of air, is particularly suited for use in welding and assembly operations.
