  • Patent number: 8302884
    Abstract: A cross-flow injector is used to introduce fluids into a chemical vapor deposition process chamber separately and simultaneously for efficiently atomizing and vaporizing the fluids. The cross-flow injector consists of a three port cavity having an inlet nozzle, a throat region, and an exit nozzle. The injector cavity is defined by the tapering of the inlet and exit nozzles to the smaller diameter of the throat region. The tapering allows for pressure differentials at the inlet, throat, and exit regions, and assures the inlet pressure being much greater than the exit region. The throat region consists of additional apertures for injecting dopants and precursors within the fluid flow. The pressure differential at the throat region atomizes and vaporizes the injected dopant and precursor fluids. In a second embodiment, the injector cavity consists of two ports, having an inlet nozzle and a throat region.

  • Patent number: 7147173
    Abstract: A nozzle for mixing and delivering two or more components and method of use thereof. One variation provides a nozzle that injects a first component, such as fuel, into a flow plume for a second component, such as nitrous oxide, for use with combustion engines. The nozzle receives two or more separate flows of components (e.g., gases and/or liquids), one of which is pressurized so as to be outputtable from the nozzle as a plume. The plume is directed so as to encompass an output extension for the other component near the plume edge, thereby enhancing mixture of the components. In addition, the plume produces a low pressure draw of the second component from the output extension, the low pressure draw varying with plume velocity, in turn varying with delivery pressure of the first component. The plume flow of the second component also atomizes the first component, further enhancing mixing.

  • Patent number: 6267585
    Abstract: A plate burner for combusting hydrogen with air as an oxidizer forms a wall portion of a combustion chamber for example of a gas turbine. The plate burner is so constructed that air and hydrogen are separately guided to the downstream surface area facing into the combustion chamber for forming a large number of diffusive microcombustion flames, thus achieving a very low mixing scale simultaneously with a high nixing intensity. The number of diffusive micorcombustion flames is so selected that the NOx content in the exhaust gas from the combustion chamber is at the most 10×10−6 cubic foot per cubic foot of exhaust gas. The hydrogen enters the entrance area into the combustion chamber either through a porous wall, and air is injected into the hydrogen environment to form inverse diffusive microcombustion flames or the hydrogen is injected through a multitude of fine holes into high velocity air jets forming regular diffusion flames.

  • Patent number: 6267820
    Abstract: An injection valve is provided with vibration to dislodge residue therefrom and to thus avoid injection valve clogging. A wave generator which preferably generates an ultrasonic sine wave, is operatively coupled to the vaporization region of the injection valve (i.e., via the injection block, via a piezoelectric valve controller, etc.). The wave may be applied to the injection valve whenever vaporization takes place, in which case a removable trap is coupled between the injection valve and the processing chamber. Alternatively, the sonic wave may be applied to the injection valve only in conjunction with a chamber cleaning process.

  • Patent number: 6089160
    Abstract: A paint injector for digital printing in which paint is deposited in metered amounts on a print medium comprises a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and an endless cable disposed around the wheel and the idler. The motor is preferably computer controlled such that the rotation of the wheel and thus movement of the cable is selectively controlled. As the wheel is rotated, paint contained within the paint reservoir coats the cable and is thus drawn by the cable in front of an air stream. The air stream pulls the paint from the cable and carries it toward the print medium. By employing a plurality of such paint injectors into a single print head, each containing a different color of paint, and secured to a computer controlled, movable carriage positioned over the print medium, a digital image can be painted by the print head on the print medium.

  • Patent number: 6076748
    Abstract: A purification device utilizing ozone, this device comprising a body member having an internal passage through which propellant gas is constrained to flow under pressure, with the internal passage forming an outlet at a downstream location in the body member. Liquid is supplied in limited quantities to the propellant gas in the internal passage, with the introduction of the liquid into the propellant gas causing thin ribbons and threads of liquid to flow into and with the gas flowing out of the outlet and to break into fine particles. An ozone supplying conduit is disposed in a central location in the outlet, with the conduit arranged to emit ozone into the propellant gas at a location near the outlet and to create a turbulent propellant gas region downstream of the ozone conduit. The propellant gas flows around the ozone conduit at a substantial velocity and thus serves to induce the flow of ozone from the conduit.

  • Patent number: 6003789
    Abstract: Mixing means, for producing a flow mixture of oil and steam, is combined with an atomizing nozzle to provide a nozzle assembly which produces a jet of very fine oil droplets. The nozzle assembly is used in conjunction with a reactor, such as a fluidized bed coker. The mixing means comprises a pipe, external of the reactor, having separate, spaced apart inlets for oil and steam. The steam inlet is upstream of the oil inlet. A reducing diameter nozzle is positioned in the pipe bore between the inlets, for accelerating the steam. The steam contacts the oil and turbulently moves down the pipe bore to produce what is known as a "bubbly flow" mixture. The mixture is fed to the nozzle, which is internal of the reactor.

  • Patent number: 5941460
    Abstract: A spray generator has a gas duct (1, 6, 10, 14, 16, 21) from which issues a stream of gas in various configurations according to the shape of the delivery end. Liquid is directed by nozzles (3, 11) or other means (13, 18, 22) transversely into the gas stream, although it may have a directional component going with that stream and/or a component to generate swirl. The relative speeds and amounts of gas and liquid cause the liquid to break up into droplets (9, 24) which form discrete clusters (5, 8) in a compact spray pattern. Secondary gas streams (17, 23) can be applied further to shape the spray pattern.

  • Patent number: 5863192
    Abstract: An object of the present invention is to achieve lower NOx combustion in response to the increasingly intensified NOx regulations for burners. The present invention provides a low nitrogen oxides generating combustion method and apparatus which utilizes effective self-induced exhaust gas recirculation before the initiation of the combustion of diffusion flames, or allows part of the combustion gas to be entrained by auxiliary fuel flow, air flow and fuel flow before the formation of the diffusion flames to further intensify the recirculation flow of the combustion gas by the diffusion flames or, in addition, which can achieve rich and lean combustion in the diffusion flames for decreasing the generation of NOx by a combination of these measures, and which are excellent in flame stability even in a low temperature atmosphere.

  • Patent number: 5827360
    Abstract: The invention relates to a method and equipment for producing foam bitumen. Water is mixed to hot bitumen under a pressure which is lower than the prevailing absolute pressure, and after this the pressure is allowed to rise and the flow rate to drop. The mixing of water and bitumen occurs in a foaming reactor (17), which is connected via a pipeline (6, 8, 9, 10) to a spray bar (1), which also acts as a heat exchanger, and the changes in the flow caused by an inclination in the spray bar are compensated by means of pipes (6) and valves (7). The entire equipment is thermally insulated, and a part of it may be provided with electric heating to prevent the bitumen from solidifying. It is possible to circulate hot bitumen in the equipment by opening a valve (12), whereby the entire equipment is brought to an operating temperature.

  • Patent number: 5654040
    Abstract: Methods and apparatus for spraying a liquid or hot melt material involve placing the material in a plurality of parallel grooves arranged across the entire width of a movable member and then causing a compressed gas to impinge upon the material in the grooves, thereby to spray the material from the grooves toward a substrate, as by extending, fiberizing or atomizing the material, or by mixing a gas with the material. For some materials of relatively high viscosity, a scraper is used to scrape the material from the grooves, and the compressed gas impinges the material while it is on the scraper, thereby to cause spraying. This provides a wide band deposition of a liquid or hot melt material with uniform material distribution across the entire width, along with improved ability to quantify the amount of material deposited on the substrate.
