  • Patent number: 6247654
    Abstract: The invention, an improved sprinkler structure equips a molded handle and sprinkler majority with internally connected waterways. A valve bar is inside the waterway with extension end extruded out of the majority and connects with a compression board through a screw. A valve opening with contracted diameter is located at the front end of waterway, thus a valve bar can block the valve opening to prevent water spraying from a water outlet. If a valve bar is compressed by a compression board to move backward, water will flow through a water outlet and enters the structure of a sprinkler. Especially, at the sprinkler majority near the side held by a user, a water outlet column connecting with internal waterway inside the sprinkler majority is equipped. A foggy water spray base, which is able to produce foggy water and control water flow is connected to the surrounding edge of the column.

  • Patent number: 6241158
    Abstract: A pop-up rotor type irrigation sprinkler has a pivotable butterfly valve body located in its riser just below the nozzle. The valve body is selectively pivotable between fully open and fully closed positions by manually turning a drive member mounted in the upper end of the riser with a hand tool. The drive member is connected to the valve body with a linkage that extends within the riser outside of the water flow path to avoid adversely affecting the water stream ejected from the nozzle. The valve body has an elliptical shape and is curved in section and downwardly concave when in its closed position. Due to its curved shape, the valve body can pivot to its vertical open position in which it rests parallel with the curved cylindrical interior wall of an internal flow tube to minimize flow resistance.

  • Patent number: 6241160
    Abstract: An atmospheric inversion layer de-stabilizer apparatus is using the energy of the water vapor present in the earth's atmosphere to destabilize an atmospheric inversion layer, as a way and to disperse the air pollutants concentrated below the inversion layer, in time to prevent photochemical reactions and smog formation. The apparatus may also be used to alleviate frost, disperse fog, and control the atmosphere's composition above of a limited geographic area. The apparatus is using a ring balloon (26) filled with lighter than air gas, to elevate vertically in the atmosphere an air transport shuttle (42), and a control platform (122) to control the altitude and the ascending and descending speed of the air transport shuttle (42) via a vertical cable (102) attached to the air transport shuttle (42) and wound on a motorized reel (146).

  • Patent number: 6237863
    Abstract: A sealed worm wheel gearbox is provided having a worm disposed on a driveshaft. The worm engages a bull gear within the gearbox. Eccentric rotatable driveshaft mounts are mounted on opposite sides of the gearbox to support the driveshaft. The driveshaft axis of rotation is offset from the eccentric rotatable driveshaft mount axis of rotation. Thus, when the eccentric shaft mounts are rotated, the driveshaft moves linearly within the gearbox. In this way, rotation of the eccentric shaft mounts enables engagement and disengagement of the worm and bull gears.

  • Patent number: 6237859
    Abstract: A system for injecting a fluid spray into a wind machine-generated airstream is provided. The system includes a wind machine that is rotatably mounted upon a central tower. The wind machine is a conventional type, generating the air stream by the rotation of a propeller. The air stream can be directed toward a target, such as an orchard, vineyard or crop for cooling, humidifying, heating or the dispersal of agricultural chemicals. The present invention can be utilized for dust control. A nozzle array is mounted proximate to and preferably onto the wind machine, downstream of the air flow. The nozzle array includes at least a nozzle wand with a base end and a nozzle end. The base end attaches to the wind machine and each nozzle end has a nozzle. The nozzle injects the fluid into the air stream, behind and away from the rear of the wind machine. A rotatable manifold distributes the fluid to the nozzle array through the fluid outlet. The manifold is ring shaped and circumferentially mounted on the central tower.

  • Patent number: 6227463
    Abstract: Tap water supply systems are flushed by opening fire hydrants and running potable water through the fire hydrants for a period of time. Since potable water usually contains chlorine, it is necessary to remove the chlorine before the water enters rivers, streams and bays in order to protect aquatic life. This is accomplished by passing the water through a diffuser attached to the fire hydrant, which diffuser contains a mesh bag with a sodium sulfite tablet therein.

  • Patent number: 6227455
    Abstract: A pop-up sprinkler has a diaphragm-type valve in the lower end thereof which is actuated by a remote pilot valve. The pilot valve may be either solenoid actuated, or hydraulically actuated by a suitable valve actuator component. In a first embodiment an upwardly opening valve actuator component assembly housing communicates with a hollow wire and hose housing. The wire and hose housing connects to the side of the cylindrical outer body of the sprinkler to position a lid of the valve actuator component assembly housing at surface level, but outside a circular ground support flange connected to the sprinkler body. In a second embodiment, the housing is situated so that the lid effectively forms part of the circular ground support flange. The valve actuator component assembly housing may contain, for example, a pilot valve coupled to a solenoid, and a regulator. The pilot valve and regulator are connected through hoses to the sprinkler body.
