    Abstract: A lower filter for a fuel injector includes a disk having an annular shape and including a plurality of filter holes. The disk is positioned upstream of a valve guide of an internal valve assembly without contacting the valve guide. The disk prevents internally generated contaminants contained in fuel flowing through the filter holes from reaching a valve guide area and a sealing area of the internal valve assembly. By installing the lower filter upstream of the valve guide and without contact to the valve guide, interference with the guidance and reciprocal movement of the valve is avoided. Application of the lower filter in fuel injectors may reduce the occurrence of injector failures by reducing the number of stuck open conditions in injectors and by reducing the number of hydro lock engine incidents without interference with the valve guide.

    Abstract: The invention relates to a premix burner with high flame stability for use in a heat generator, preferably in the combustion chamber of a gas turbine. Modern, lean-operated premix burners enable very low noxious emissions, but sometimes operate very close to the extinction limit. To increase the stability of the lean premix combustion by increasing the distance between flame temperature and extinction limit temperature the invention proposes to equip the burner in the mixing zone (200) with a net-like structure (201) for the premixing of combustion air and fuel. According to a preferred embodiment, the net-like structure (201) consists of a plurality of layers of individual wire mesh fabrics (202) arranged at a distance from each other. The wire mesh fabrics (202) are preferably equipped with an oxidation-promoting, catalytically active surface.

  • Patent number: 6830062
    Abstract: A dripper apparatus for a water spigot includes a coupler having a threaded female member for connecting to a water spigot. A generally cylindrical elongate member has a longitudinal portion in fluid communication with the female member. The longitudinal portion has an upper portion that defines a seat within the female member. A flow controller sits on the seat. A filter screen upstream the flow controller collects particles in water flowing therethrough so that the controller does not become clogged. The flow controller includes a housing that is provided with an upper inlet for receiving a first flow rate of water from a water spigot. The housing also includes a cavity therewithin and the cavity is in fluid contact with the upper inlet. A flexible membrane is housed within the cavity and floats when water enters the cavity via the upper inlet. The upper inlet is slotted at the top thereof for further filtering water flowing therethrough.

  • Patent number: 6793148
    Abstract: A method and apparatus for producing man-made snow without using either compressed air or high-speed fans. The method makes use of a special water nozzle that is designed to provide a high volume spray of water particles that, owing to their size distribution (having a median size of between about 100 and 200 microns) in the spray, are readily susceptible to conversion to ice crystals as they settle to earth under favorable ambient conditions. Preferably, water applied to the nozzle is seeded with artificial nucleation sites so that water particles in a spray containing such sites are more susceptible to conversion to ice crystals as the particles settle to earth.
