  • Publication number: 20170115003
    Abstract: Methods, burner, apparatuses, and systems are provided for controlling a velocity of a jet of gas exiting a burner when the gas is heated or not and at a corresponding second higher temperature or lower first temperature. Through the use of a temperature-sensitive magnetic valve, the flow of a gas can be redirected to maintain velocity of the gas as delivered to a combustion chamber based on the temperature of the gas. The temperature-sensitive magnetic valve can redirect flow of the gas based on the magnetic state of a ferromagnetic material. The state of the temperature-sensitive magnetic valve changes based on the temperature of the gas to maintain the velocity of the gas delivered through an outlet of the burner to the combustion chamber. Thus, heated gases and standard temperature gases can be delivered at approximately equal velocities thus maintaining flame size and shape.

  • Patent number: 9618203
    Abstract: A plurality of independently flow rate-controlled flows of fuel may be preheated at a heat exchanger (or both oxidant and fuel at separate heat exchangers) by heat exchange with a hot shell-side (heat transfer) fluid. The separate flows of hot fuel are directed to associated separate burners where they combust with flows of fuel to produce hot combustion gases. The hot combustion gases are used to preheat the hot shell-side fluid at a recuperator or regenerator.

  • Patent number: 9285113
    Abstract: A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis. The action of the angling away together with staging of the oxidant between primary and secondary oxidant injections allows achievement of distributed combustion conditions.

  • Patent number: 9243182
    Abstract: The present invention is a cryogenic subterranean fracturing fluid, comprising a liquefied industrial gas and a viscosity increasing additive. The liquefied industrial gas may be liquefied carbon dioxide, liquefied nitrogen, or a blend of the two. The liquefied industrial gas mixture should be substantially free of water. In this context, substantially free of water means less than 10% water by volume, or preferably less than 5% water by volume. In addition to the viscosity increasing additive, a proppant may be added to the fracturing fluid. In addition to the viscosity increasing additive and/or proppant additional additives may be added to the liquefied industrial gas as required.

  • Patent number: 9206507
    Abstract: Disclosed are homoleptic diazabutadiene nickel precursors used for the vapor deposition of nickel-containing films. The precursors have the general formula Ni(R-DAD)2, wherein R-DAD stands for substituted 1,4-diazabuta-1,3-diene ligands. The sole presence of the Ni—N bonds was also considered to avoid too high intrusion of other elements, such as carbon, into the nickel-containing films. The flexibility of the Ni—N bond in terms of film deposition also allows using the molecules for nickel, nickel-nitride, nickel-carbonitride, nickel oxide or any other type of nickel-containing films. The nickel-containing film depositions can be carried out by thermal and/or plasma-enhanced CVD, ALD, and pulse CVD or any other type of depositions methods.

  • Patent number: 9103019
    Abstract: Methods and compositions for depositing a metal containing thin film on a substrate comprises introducing a vapor phase metal-organic precursor into a reaction chamber containing one or more substrates. The precursor has at least one ?-diketiminato ligand, and has the general formula: M(R1C(NR4)CR2C(NR5)R3)2Ln wherein M is a metal selected from nickel, cobalt, ruthenium, iridium, palladium, platinum, silver and gold. Each of R1-5 is an organic ligand independently selected from H; and a C1-C4 linear or branched, alky group, alkylsilyl group, alkylamide group, alkoxide group, or alkylsilylamide group. Each L is independently selected from: a hydrocarbon; an oxygen-containing hydrocarbon; an amine; a polyamine; a bipyridine; an oxygen containing heterocycle; a nitrogen containing heterocycle; and combinations thereof; and n is an integer ranging from 0 to 4, inclusive. A metal containing film is deposited onto the substrate, while the substrate is maintained at a temperature between about 100° C.

  • Publication number: 20150216161
    Abstract: The invention may be broadly defined as the addition of Argon to FFPE procedures as an RNA stabilizing agent. Argon is an inert gas from the Noble gas group with low saturation concentrations in water. It is therefore highly surprising that Argon would have any effect on RNA stability in the presence of Formalin, or any other chemical. This property of Argon appears to be specific in that other inert gases fail to show any RNA stabilizing effect.
