    Abstract: A fuel nozzle includes a first plate, a second plate axially spaced from the first plate, a shroud extending between the first plate and the second plate, thereby defining a plenum. Tubes extend through the first plate, the plenum, and the second plate. An inlet of each tube is defined through the first plate, and an outlet of each tube is located downstream of the second plate. The tube inlets have a first size, the tube outlets have a second size different from the first size, and the walls defining the tubes have a transition portion between the inlet and the outlet. The transition portion has an axial length from the fuel injection port to a location having a diameter of the second size. The transition portion of a first tube extends a first axial length and the transition portion of a second tube extends a different second axial length.

  • Patent number: 9789431
    Abstract: A cleaning device for a dust filter has a flow duct extending between an entry opening and an exit opening. An annular chamber surrounds the flow duct. Gas-inlet connectors are provided for inflow of pressurized gas into the annular chamber. Nozzle gaps delimited by nozzle-gap walls open toward the flow duct. The annular chamber has an upper annular shell and a lower annular shell interconnected pressure-tightly in a connection region. The gas-inlet connectors are molded on the upper annular shell. The lower annular shell is predominantly flat, extends horizontally or downwardly toward the nozzle gaps, and forms the lower nozzle-gap wall. In order to meet highest demands in terms of hygiene, in the connection region the angle at which the annular shells mutually abut in the annular chamber is at least 90°. Gaps and constrictions are thus avoided.

    Abstract: A nebulizer for a charged aerosol detection (CAD) system is disclosed. The nebulizer is provided with a spray emitter for generating a spray of droplets within a central region of a spray chamber. The central region is separated from an upper region by a horizontally projecting rib, which defines a passageway between the central and upper regions. The major direction of droplet travel within the upper region is substantially reversed with respect to the major direction of droplet travel within the central region. Larger droplets are unable to negotiate the turn from the central to upper regions and impinge on a rear surface of the spray chamber. Removal of larger droplets has the advantageous effect of enabling the detector to sense a smaller range of particle sizes, which establishes a relatively steady electrical current at the detector.

  • Patent number: 8597729
    Abstract: In a method and system for forming microbeads, a polymer solution includes particles and a polymer dissolved in a solvent. A stream of the polymer solution flows into a chamber. A focusing fluid contacts and focuses the polymer stream in the chamber. The focusing fluid and the focused polymer stream flow, as a single flow stream, out from the chamber. Pendant droplets detach from a leading end of the single flow stream to form the microbeads. The focusing fluid reacts with the polymer solution to form functional groups at a surface of the microbeads for binding with biorecognition molecules. In the system, a flow focusing apparatus includes a flow focusing body shaped to define the chamber. Microbeads formed according to the methods and systems are also disclosed.

    Abstract: The spray gun is provided with a nozzle section which mixes gas into raw material liquid and also ejects the raw material liquid. The internal space of the nozzle section has an introduction path into which the raw material liquid is introduced, an open portion in which a flow path is enlarged more than the introduction path, thereby ejecting the raw material liquid in a fine particle form, a reduced diameter portion in which a flow path is made narrower than the open portion, thereby re-aggregating the raw material liquid in a fine particle form, and an ejection orifice portion which ejects the raw material liquid to the outside. In the nozzle section, a gas introduction hole which introduces gas into a base-end-side portion of the open portion is formed.

  • Publication number: 20130214067
    Abstract: A device for manually painting a large surface using a spray gun connected to a paint feed line for the supply of an enamel paint and to a pressure line for the provision of compressed air. After the manual actuation of an operating switch arranged on a handle piece, the spray gun sprays the enamel paint by compressed air via a spray head to apply the enamel paint onto the surface. The spray gun includes means such that it can be moved manually along the surface. The means include an extension rod, at one end of which the spray gun is attached by the handle piece and which is configured such that, when held by an operator on an arm holder configured at the opposite end, it extends from the elbow along the forearm of the operator and beyond the distal end of the forearm.
