Including Additional Dispersing Plate Or Obstruction In Mixing Chamber Patents (Class 239/432)
  • Patent number: 8083156
    Abstract: A dispersion apparatus for dispersing a treating agent into a fluid treatment system that includes a flow duct in which a fluid stream flowing through the duct is mixed with the treating agent. The apparatus is based on a multi-pipe lance positioned in the stream flow, where each pipe supplies a minimum of feed discharge nozzles (typically one to four), and the individual pipes branch off from the same location. Use of the multi-pipe lance, in combination with a suitable baffle, results in better overall dispersion/distribution of the injected medium by surface area. By improving the surface area distribution, better utilization of the injected sorbent can be achieved. The baffle acts to generate a low pressure zone on its downstream side and creates a high-intensity turbulence plume in the fluid. The orifices of the pipe are located to inject the treating agent into the turbulence plume to better distribute and intermix the injected treating agent into the surrounding fluid.

  • Patent number: 8070074
    Abstract: A bathing apparatus includes an in-line mixing unit and a hand operated injecting unit. The mixing unit is coupled between a water supply pipe and a water dispensing device, such as a showerhead and is in fluid communication with the hand operated injection unit. The injection unit, upon user demand, draws a controllable predetermined quantity of bathing fluid from a standard off the shelf purchased bottle of bathing fluid, such as a bottle of bath oil, and then ejects, upon user demand and in a hands free operation, the drawn bathing fluid, at a user selected flow rate. The ejected bathing fluid passes to the mixing unit which causes the ejected bathing fluid to be mixed within a stream of water being delivered to the water dispensing device.

    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: 7516909
    Abstract: An apparatus for mixing an additive into a fluid to form a settable mixture includes a main fluid passageway having an inlet for receiving a supply of the fluid and an outlet for dispensing the fluid, the passageway having a longitudinal axis. The apparatus includes a control valve defining a portion of the main fluid passageway and configured for selectively controlling the flow of fluid in the passageway, an additive injector disposed in the passageway and having an emitter disposed in close relationship with the axis and oriented toward the outlet. A static mixer is disposed between the injector and the outlet for enhancing the uniform mixing of the additive and the fluid. Connection points between the inlet, the valve and the static mixer are configured for smooth transition of fluid and the prevention of at least one of the collection and premature setting of the mixture.

  • Patent number: 7337856
    Abstract: An apparatus, system and method for suppression of fires are provided. In accordance with one embodiment of the invention, a housing is provided with a first opening (or set of openings), a second opening (or set of openings) and a flow path defined between the first and second openings. A fire-suppressing gas is produced, such as from a solid propellant composition, and is introduced into the flow path in such a way that a volume of ambient air is drawn from a location external to the housing, through the first opening and into the flow path. The volume of ambient air may be subjected to an oxygen-reducing process and mixed with the fire-suppressing gas to form a gas mixture. The gas mixture is discharged from the flow path through the second opening and into an associated environment for suppression of a fire located therein.

  • Patent number: 7152396
    Abstract: A lean NOx trap operating in a lean NOx exhaust stream is progressively regenerated, sector to sector, for efficient operation of the trap and conservation of reducing gas used in the regeneration. A reductant gas distributor is inserted in the exhaust upstream of the trap. Reductant gas is carried into the exhaust duct through a conduit portion and the reductant gas stream diverged and directed through a distributor into selected cells of the trap. The NOx in the selected cells is reduced to N2 while lean NOx exhaust continues to flow through the remainder of the trap. By relative movement of the reductant gas distributor and the trap, the entire trap is progressively and continually regenerated while still preforming as a NOx trap.
