  • Publication number: 20110057056
    Abstract: A monolithic fuel injection head for a fuel nozzle includes a substantially hollow vesicle body formed with an upstream end face, a downstream end face and a peripheral wall extending therebetween, an internal baffle plate extending radially outwardly from a downstream end of the bore, terminating short of the peripheral wall, thereby defining upstream and downstream fuel plenums in the vesicle body, in fluid communication by way of a radial gap between the baffle plate and the peripheral wall. A plurality of integral pre-mix tubes extend axially through the upstream and downstream fuel plenums in the vesicle body and through the baffle plate, with at least one fuel injection hole extending between each of the pre-mix tubes and the upstream fuel plenum, thereby enabling fuel in the upstream plenum to be injected into the plurality of pre-mix tubes. The fuel injection head is formed by direct metal laser sintering.

  • Publication number: 20110049267
    Abstract: A two component spray gun with low/high flow rates allows the operator to spray in confined areas at lower flow without having to change the mix module. The lower flow reduces undesirable “spray back” and will also help reduce material waste. Pneumatic piston 12 travel, which determines on/off fluid flow, can be selected on the fly to either close the fluid ports 14 which stops fluid flow, partially open the fluid ports 14 which limits fluid flow, or to fully open the fluid ports 14 to allow for maximum flow. Pneumatic piston 12 travel can be limited by means of a simple multi-position mechanical stop plunger 16.

  • Publication number: 20110011951
    Abstract: The invention relates to a nozzle that has direct compressed air injection into the nozzle. The injection of compressed air directly into the nozzle thereby eliminates the need for additional means by any separate apparatus to collect the material prior to discharge of the material. The compressed air in the nozzle results in the material being drawn into the nozzle's hollow rod upstream inlet end and simultaneously discharged through the chamber's downstream outlet end through the attached female end of the external hollow rod. The invention can be used for liquid, slurry or dry material and can be immediately switched from one type of material to another without making any adaptations or changes to the invention.

    Abstract: A system for cold gas dynamic spraying of particulate material has a de Laval nozzle and two or more radial particle inlets located between the throat and the outlet of the nozzle, the two or more particle inlets arranged symmetrically around a linear flow path of the nozzle. Blocking of the inlets is reduced by controlling pressure of particle carrier gas to provide a stable particulate material injection pressure before and during introduction of working gas into the nozzle, and/or by clearing the particle inlets of residual particles after a spraying process. Such a system and associated method combines benefits of both downstream and upstream cold gas spray systems. Further, a nozzle for spraying particulate material having a cross-sectional shape that is narrower in a middle section compared to edge sections provides coatings with superior cross-sectional profiles.

  • Publication number: 20100006670
    Abstract: A device for ejecting an at least diphasic mixture includes an injection inlet for a liquid and a gas, a distribution chamber for producing a first liquid-gas mixture, an ejection nozzle of the first liquid-gas mixture in a main direction defined by an axis-vector. The ejection nozzle has a geometry comprising, on its length at least, a minimal section or neck at a location of the axis-vector. Among others things, due to the nozzle geometry, the expansion obtained inside the ejection nozzle allows the first liquid-gas mixture from the distribution chamber to be converted into a second mixture, according to the flow configuration, consisting for instance of a diphasic mist jet having an ejection range and liquid particle size that can be controlled according to the liquid and gas mass flow and to the absolute pressure at the injection inlet.

  • Patent number: 7621466
    Abstract: Disclosed is a nozzle for cold spray and a cold spray apparatus using the same. The nozzle for cold spray includes a hollow-type nozzle section. The nozzle section includes a convergence inlet section in which the cross-sectional area is converging, a throat area connected to the convergence end point of the inlet section, and an outlet section connected to the end point of the throat area. The nozzle for cold spray is provided with a spray tube located inside the convergence inlet section, the spray tube having a spray hole formed at its end point in such a way as to be placed at the throat area or the outlet section beyond the throat area. The speed of the powder flow at the outlet end point of the outlet section reaches 300-1,200 m/s.

  • Patent number: 7604780
    Abstract: An ozone disinfection apparatus is provided whereby the ozone is dispersed in a vapor. The use of an ozonated vapor increases saturation of the article, surface or area being disinfected. Ozone from a generator on-board the apparatus is forced into contact with a fluid, such as water, to form the vapor. Particle size of the vapor is controlled by passing the vapor through an atomizer.

    Abstract: The present invention provides a spray method and spray apparatus for bentonite-based material that allow forming a bentonite layer of high dry density. A spray apparatus 1 comprises a supersonic nozzle 2, to which a compressor 5 and a bentonite container 6 are connected. The supersonic nozzle 2 is fed compressed air from the compressor 5 and a bentonite-based material from the bentonite container 6. The compressed air, mixed with the bentonite-based material, is accelerated to supersonic speed when passing through a constriction portion 14 of the supersonic nozzle 2, and is sprayed at supersonic speed out of a jet orifice 11.
