    Abstract: A process for the producton of pure syngas (hydrogen and carbon dioxide) by fast gasification of liquid, muddy, or solid raw materials, either produced for the purpose or from industrial processes in which they can not be recycled, or fuels from wastes or biomass, which process is carried out in a modular reactor including a raw materials feeding area, a gasification area, a discharging area of the residues in powdery or vitrified form. The obtained syngas is sent to a purification and compression step.

  • Patent number: 7229667
    Abstract: Compositions comprising a reactive gas and a matrix gas are disclosed, as well as articles of manufacture and methods of making the articles. The methods of manufacturing preferably employ zeolites to remove moisture from the reactive gas and from the matrix gas, and then combine the moisture reduced gases either in a container, or prior to filling a container, which has been previously vacuum-baked and passivated. The invention produces stable standard gas compositions having improved shelf-life.

  • Patent number: 7211765
    Abstract: The invention relates to a shielding gas for use in the arc welding of metallic work pieces. The invention further relates to a process for the arc welding of metallic work pieces using consumable electrodes, whereby a shielding gas stream is supplied to the work piece adjacent to the electrode. According to the invention, for shielding gases recommended for use in the MSG welding, preferably the MAG welding, of rust-proof steels, especially nickel-based materials, specialty steels, or high-alloy steels, a) if the shielding gas contains no helium, it contains carbon dioxide in a proportion of between 0.001% by volume and 1.9% by volume and b) if the shielding gas does contain helium, it contains carbon dioxide in a proportion of between 0.001% by volume and 0.9% by volume, in addition to argon, nitrogen, and, if applicable, helium.

  • Patent number: 6991748
    Abstract: In a process for the production of a shielding gas mixture argon is withdrawn from a liquid argon supply, vaporized and mixed with a gas premix. The gas premix contains helium and/or argon and a doping gas. A shielding gas mixture prepared this way is outstandingly suited, especially because of the helium content, for arc welding of aluminum and aluminum alloys.

  • Patent number: 6963046
    Abstract: A process gas for use in laser welding with a laser beam focused onto the work piece to be welded. The inventive process gas comprises helium, nitrogen, and at least one of carbon dioxide in an amount of up to 40% by volume, and oxygen in an amount of up to 30% by volume. The gas may comprise not more than 85% by volume of helium. Also disclosed are methods of laser welding using the inventive process gas. The invention is suitable for laser welding of low-alloy steels and coated, especially zinc-coated steels.

  • Patent number: 6847007
    Abstract: A process gas and a process of laser machining, such as laser beam fusion cutting or laser beam welding is provided. A gas mixture that contains at least oxygen and hydrogen, in addition to an inert has, is used as the process gas. The ratio of oxygen to hydrogen in the process gas is hypostoichiometric with respect to the reaction 2 H2+O2+?2 H2O, which causes the process gas to exhibit a reductive effect.

    Abstract: The occurrence of hypercapneic acidosis in a fetus during a laparoscopic procedure carried out on a pregnant female, is prevented or ameliorated by inclusion in or addition to the carbon dioxide insufflation gas, of a nitric oxide donor, e.g., ethyl nitrite. Administration of nitric oxide donor in insufflation gas causes increase in fetal cerebral oxygenation.
