  • Patent number: 7780095
    Abstract: The present invention relates to an apparatus utilizing ultrasonic vibrations to force movement of protrusions to spray a fluid. The apparatus includes a horn with an internal chamber. Within the internal chamber of the horn are protrusions extending from a wall of the chamber. When the horn is vibrated, a fluid is expelled from the horn by the oscillation of the protrusions. Fluid to be expelled from the horn enters the internal chamber of the horn through at least one channel passing through a wall of the horn and leading into the chamber. After passing through the horn's internal chamber, the fluid exits the horn by passing through a channel originating in the front wall of the chamber and ending at the horn's radiation surface. A transducer may be connected to the horn's proximal end to generate ultrasonic vibrations throughout the length of the horn.

  • Patent number: 7753285
    Abstract: An ultrasound apparatus capable of mixing and/or atomizing fluids is disclosed. The apparatus includes a horn having an internal chamber through which fluids to be atomized and/or mixed flow. Connected to the horn's proximal end, a transducer powered by a generator induces ultrasonic vibrations within the horn. Traveling down the horn from the transducer, the ultrasonic vibrations induce the release of ultrasonic energy into the fluids to be atomized and/or mixed as they travel through the horn's internal chamber. As the ultrasonic vibrations travel through the chamber, the fluids within the chamber are agitated and/or begin to cavitate, thereby mixing the fluids. Upon reaching the front wall of the chamber, the ultrasonic vibrations are reflected back into the chamber, like an echo. The ultrasonic vibrations echoing off the front wall pass through the fluids within the chamber a second time, further mixing the fluids.

  • Patent number: 7264179
    Abstract: A nebulization system, which creates a uniform fog of tiny suspended liquid droplets, to lubricate the surfaces of MEMS devices. These droplets fall over the edge of a baffle and are then mixed with an umbrella-like sheet of N2 turbulation gas to generate a uniform cloud of droplets that fill a passivation chamber. The MEMS device is then positioned in this uniform cloud of lubricant droplets for a specified amount of time, thereby uniformly lubricating all the surfaces of the device. The system uses a laser monitoring approach to control the uniformity of the lubricant cloud by providing feedback to the system to control the flow of gases. The system also equalizes the pressure around the sample device seal to prevent gases from entering or exiting the chamber and thereby influencing the environment inside the chamber.

  • Patent number: 6394792
    Abstract: An improved burner for combustion of fuel gas with air in a manner to result in low NOx, the burner is generally circular and has a refractory tile and gas tips. The gas tips are spaced around the outer circumference of a generally circular passageway in the burner tile, each gas tip is positioned to cause the fuel gas to entrain furnace flue gas. Each gas tip has one or more ports, an ignition port and at least one firing port. The ignition port injects fuel through a passageway to the burner tile. The firing port injects fuel gas in the direction that is generally upward with respect to the pathway of the ignition port. This causes fuel gas to entrain combustion products from the flue gas, the resulting mixture of fuel gas and flue gas is directed out of the burner tile to mix with combustion air that is discharged through the burner tile.

  • Patent number: 6193502
    Abstract: The fuel is fed centrally into a fire tube (3), where it is mixed with combustion air in a combustion zone. The air exits through first and second air line nozzles (4 or 5) which are arranged in two directly adjoining rows (6, 7) and inclined in the direction of counterflow at an angle of 60° to the axis of the fire tube. The distance (x) between the fuel nozzle (9) and the openings of the first air line nozzles (4) is 0.70 times the diameter of the fire tube. In addition, the second air line nozzles (5) extend into the fire tube by a distance (y) which is 0.17 times the diameter of the fire tube. The total cross-section of the second air line nozzles (5) is 0.6 times that of the first air line nozzles (4). A highly turbulent toroidal eddy forms inside the fire tube (3) which generates a very homogeneous mixture across the cross-section of said fire tube (3). This results in lower NOx values and even temperature distribution already inside the fire tube.

  • Patent number: 6174160
    Abstract: Method and apparatus to prevaporize and premix liquid and/or gaseous fuels with air in two stages at two different temperatures prior to combustion. The invention is directed to the entry of a finely atomized liquid fuel, such as No. 2 diesel, into an inlet end of an annular chamber. Air is mixed with finely atomized liquid fuel, preferably generated by a small flow number liquid fuel nozzle, in a first chamber of the annular chamber at a first (relatively high) temperature for a relatively long residence time. The air and liquid fuel is moved into a second chamber of the annular chamber where a secondary hotter air is injected into the annular chamber by a plurality of staggered high velocity jets to prevaporize and premix the combined fuel and air mixture at a second higher temperature, but for a shorter time. The intense prevaporization and premixing make the mixture suitable for entry into a combustor, but without the need to add water or steam to keep pollutant emissions low.
