  • Patent number: 7731100
    Abstract: Diverse methods of utilization and the corresponding, related modifications, of linear type, Variable Gas Atomization (VGA) nozzles and lances are described. Therein is joined the mixing and gas atomization of chemicals that react to form active products that further react with harmful flue gas constituents of combustion so as to enable their effective collection. One version combines, in a lance assembly of nozzles, the injection of reactants, in the form of finely divided dry solids conveyed in a carrier air stream, and the fine atomization of water, aqueous solutions or slurries. Atomization of such streams is employed to effectively wet the surfaces of the dry particles and, thereby, promote the rapid sorption of gaseous constituents of flue gas being treated. Another version simultaneously mixes and atomizes reacting chemicals to produce, and release into the flue gas stream, strongly oxidizing, transient, species of their reaction products.

  • Patent number: 7730909
    Abstract: An accessory for a vapor generator, such as a smoke or fog machine, includes an elongated member that connects to an output nozzle of the vapor generator. The elongated member has one or more perforations formed in its sidewall along its length. A vapor generated by the vapor generator travels through an interior of the elongated member and escapes through the perforations to the ambient atmosphere. The effect creates a curtain of smoke or fog.

  • Publication number: 20100078506
    Abstract: A fuel nozzle includes a hub with a plurality of output fuel holes arranged perimetrically around the hub. At least two plates located inside the hub define fuel flow passages between an input fuel flow and the output fuel holes. A plurality of enclosures is located between an inner surface of the hub and an outer one of the plates. Each enclosure is in fuel flow communication with first ones of the output fuel holes and the input fuel flow to define a first one of the passages. The two plates define a second one of the fuel flow passages which is in fuel flow communication with the input fuel flow and with second ones of the output fuel holes.

  • Patent number: 7591900
    Abstract: A nozzle for supplying a treatment liquid which makes it possible to perform uniform cleaning to a surface of a substrate even in a case where the size of a substrate is large. A slit-shaped ejection hole is formed at the lower end of the nozzle for supplying a treatment liquid. In the nozzle, a passage for supplying a treatment liquid which leads to the slit-shaped ejection hole is formed by bonding two nozzle parts to each other. Projections are provided on the abutting surface of at least one of the two nozzle parts so as to divide a treatment liquid flowing downward through the supply passage into left and right.

  • Publication number: 20090050707
    Abstract: Adjustable nozzles for directing a solid-stream of fluid and associated methods for using the same are provided. According to one embodiment, the adjustable nozzle includes a base member having an aperture therethrough defining a nozzle inlet. The nozzle includes a plurality of elongate vanes each having first and second ends. The first ends of the vanes extend from the base member in a circumferential configuration so as to form an interior region. The second ends of the vanes are operable to define an expandable nozzle outlet. The nozzle includes a liner extending from the nozzle inlet to the nozzle outlet within the interior region. The liner is structured to direct the fluid from the nozzle inlet to the nozzle outlet. Each of the plurality of vanes is biased towards the liner to thereby support the liner and control the flow of the fluid therethrough.

  • Patent number: 7415827
    Abstract: In an air mixing arrangement wherein a primary fluid is introduced through an opening in a wall to be mixed with a secondary fluid flowing along the wall surface, the opening is airfoil shaped with its leading edge being orientated at an attack angle with respect to the secondary fluid flow stream so as to thereby enhance the penetration and dispersion of the primary fluid stream into the secondary fluid stream. The airfoil shaped opening is selectively positioned such that its angle of attack provides the desired lift to optimize the mixing of the two streams for the particular application. In one embodiment, a collar is provided around the opening to prevent the secondary fluid from contacting the surface of the wall during certain conditions of operation. Multiple openings maybe used such as the combination of a larger airfoil shaped opening with a smaller airfoil shaped opened positioned downstream thereof, or a round shaped opening placed upstream of an airfoil shaped opening.

    Abstract: A steamer head for use with a steaming system for cleaning or smoothing fabric surfaces. The steamer head comprises a housing having a plurality of branches that extend between a base region and a front applicator face. The branches are disposed at an angle relative to each other so that they radiate outwardly from the base region in a fan shape. An inlet in a rear wall of housing is used to connect the steamer head to a hose extending outwardly from a remote steam-containing reservoir. An interior cavity is formed in the base region of the housing and is operationally connected to a bore in the inlet and thereby to the hose. Each of the branches includes a chamber that arises in the interior cavity and terminates in an outlet formed in the front applicator face. One or more of the branches and the chambers therein preferably are oriented so that they are disposed at an angle other than ninety degrees to the front applicator face.
