  • Patent number: 7306045
    Abstract: A multi-stage fluid power turbine having application as a fire extinguisher to be ideally carried by a fire truck (e.g., a tanker or a pumper) so as to fight outdoor fires. An impeller and a propeller are located at one end of the fire extinguisher, and a fan is located at the opposite end. The propeller and the fan are mounted on a common inner shaft so as to rotate in a first direction. The impeller is mounted on a hollow outer shaft or tube that surrounds the inner shaft. The impeller includes a plurality of curved blades, each of which having a fluid duct running therethrough. Water under pressure being supplied from a source to the impeller blades is ejected from the fluid ducts thereof and thrust against the blades of the propeller, whereby to impart a rotational force to the propeller and a corresponding rotational force to the fan. The water ejected from the curved impeller blades causes the impeller to rotate in an opposite direction.

  • Patent number: 7290722
    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.
