  • Patent number: 8910890
    Abstract: Tracer particles together with air are jetted from a nozzle of a seeder into a hood, the air is guided by a collision surface of the hood, deflected to a downstream side in an airflow direction in a wind tunnel, and flows out into the wind tunnel through an opening of the hood. Tracer particles having a large diameter fly straightly without being drifted by the deflected air and collide with the collision surface and are trapped thereon and are prevented from being supplied into the wind tunnel. Tracer particles having a small diameter are drifted by the deflected air, thereby deflected, and supplied into the wind tunnel without collision with and adhesion to the collision surface.

The spray system has a central nozzle for the primary fluid and a nozzle for the secondary fluid. The nozzle housing has a tubular design and the central nozzle is provided with a central passage for the primary fluid. The passage, as seen in the flow direction, has convergent inlet region, a constriction and a divergent outlet part. An outlet opening for the secondary fluid is arranged on the downstream end of the nozzle housing and an outlet opening generates a spray jet of secondary fluid that surrounds the primary fluid exiting the central passage in a substantially ring-shaped manner.

    Abstract: An elongated pipe conduit snow making tower, and assembly method, having an upper end spray nozzle head and pivotally supported on a support pipe for vertical inclination by a hydraulic ram jack enabling infinite non-preselected incremental inclinations. A ram safety latch automatically latch/catches the tower pipe if the jack leaks. Secondary and tertiary external flexible water hoses are selectable to feed associated spray head snowmaking nozzles, and an internal compressed air conduit feeds spray head seeding nozzles. Secondary and tertiary ball valve assemblies mounted on a water feed block are outlet coupled to their respective hoses. In drain condition turbulent primary water continually washes against a valve ball flow closure side for an anti-freezing effect. The spray head is a four-piece modular planar stack up of disks each carrying spray nozzles that all discharge forwardly away from the pipe tower in generally parallel spray patterns.

  • Patent number: 7156320
    Abstract: A clog-resistant injector spray nozzle allows relatively unobtrusive insertion through a small access aperture into existing ductwork in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle comprises an easily cleaned and easily replaced straight liquid tube whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube until they both exit the injector, thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.

  • Patent number: 5147412
    Abstract: The invention relates to a process in which a melt is mixed with, and emulsified in a colder aqueous phase at a temperature below the crystallization point of the molten compound, the melt only solidifying in the form of the dispersed particles after the emulsification step. To this end, the melt is sprayed into the aqueous phase to form a preliminary emulsion (12) and the preliminary emulsion is finely dispersed for 0.005 s to 0.15 s in a following homogenization nozzle (8) to form an emulsion (15) which then solidifies to form the final crystal suspension. The particle size can be clearly and reproducibly adjusted through the nozzle pressure during the emulsification step. The process may be used in particular for the production of highly concentrated dispersions of high-melting organic materials.
