  • Patent number: 7246756
    Abstract: A water sprinkler for irrigating lawn and garden areas has two axes of movement, one transverse to the other. A barrel moves or oscillates on one horizontal axis to direct water spray from nozzles carried on the barrel across the length of the area, and the nozzle outlets also simultaneously move or oscillate on axes transverse to the barrel axis to spray water across the width of the area. As the nozzle outlets move or oscillate in the two transverse directions, the ground area is irrigated uniformly over time by application of water in a criss-cross pattern. The area sprayed can be surprisingly large compared with single-axis oscillators, or the area may be limited to a single row or a narrow rectangular area, by adjustment of the barrel and outlet movement and/or the water pressure.

  • Patent number: 7237731
    Abstract: A fuel injector has a housing extending along a longitudinal axis between an inlet and an outlet. A seat assembly is disposed in a body proximate the outlet. The seat assembly includes a flow portion and a securement portion. The flow portion extends along the longitudinal axis between a first surface and an orifice disk retention surface at a first length. The flow portion has a seat orifice extending therethrough and an orifice disk coupled to the orifice disk retention surface so that the orifice plate is aligned in a fixed spatial axial orientation with respect to the flow portion. The securement portion extends along the longitudinal axis away from the orifice disk retention surface at a second length greater than the first length. A method of maintaining a fixed spatial axial orientation and dimensional symmetry of at least one of the seat and orifice disk in the body is disclosed.

  • Patent number: 7168636
    Abstract: An apparatus, method and system for applying a biologically active or chemical substance to a relatively large volume harvested or pre-harvested crop includes relatively small container of a mixture biologically active or chemical substance and water in fluid communication with fluid conduit. A pump moves mixture from the bottle through the conduit. A source of pressurized air is in fluid communication with the conduit to aerate the mixture. The aerated mixture is expelled through a nozzle at distal end of the conduit. In one aspect, the controller can monitor speed of the pump by monitoring operating voltage of the pump. Speed of the pump can be adjusted to adjust application rate. In one aspect, a process combines a flow of air through an orifice with the metering of a low volume of additive, such as an aid to preservation, to a crop as it is being cut or harvested to provide for even distribution of the additive to the crop.

  • Patent number: 7168633
    Abstract: A spraying device comprises a spraying plate, having a plurality of tiny holes, a vibrating element, set on a periphery of the spraying plate, and driving a vibrating movement thereof, a wrapping layer, made of soft material and tightly surrounding the vibrating element, sealing the vibrating element from the liquid, and a fastening cap, allowing for quick mounting and dismounting of the spraying device; wherein the vibrating movement of the spraying plate causes liquid adjacent to a lower side of the spraying plate to be periodically compressed and thereby to be pressed through the holes of the spraying plate, and wherein the wrapping layer prevents external interference with the vibrating movement, at the same time minimizing transmission losses of vibrational energy, enhancing effectivity of spraying.

  • Patent number: 7165625
    Abstract: A method of stopping and containing fires involving, in one embodiment, taking the fumes from a turbine, jet or any chemical source, and running it through a giant muffler, radiator, or pipe. The radiator cools the fumes down from the engine or chemical store. This is a system that uses the fumes to cool the fire down, it will suck the heat and oxygen away, and replace it with a non-combustible gas. This system can also be used to put out architectural fires, by blowing the fumes in the building from one side, keeping oxygen from entering the building, by building up pressure, until no more oxygen can enter the building.

  • 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.
