Abstract: A nozzle mounting and control system for use in sprayers comprising multiple sets of nozzles mounted in the operating position on a sprayer boom. Control valves are operable to select which sets of nozzles are operating at any given time. The valves may be remote controlled and may further incorporate a rate controller to maintain a chosen application rate as speed varies. This application rate may be varied conveniently. The rate controller may be a present rate controller such as measures the speed and total fluid volume delivered and then adjusts the pressure to maintain the application rate, or may be a novel rate controller which measures the speed and fluid pressure and then adjusts the pressure to maintain the application rate. Either rate controller would operate the control valves to select the proper combination of operating nozzles in addition to adjusting the pressure.

Abstract: A blanket for smothering fires or protecting items from fire, comprised of a wettable polymer capable of high volume water retention, a water reservoir and heat activatable valves or water source to permit water to flow from the reservoir to wet the polymer through gravity fed conduits. For fire extinguishing, such as well-head fires, the blanket further comprises a heavy metal framework and an under-blanket support. The blanket is weighted and sized to cover the well-head fires with sufficient wetting to maintain it in place for sufficient time for smothering of the fire with an airtight closure. Uses of the reservoir-connected blanket include houses and mobile homes, protection suits and doorway mounts. In an embodiment used to protect valuable items, the polymer portion of the blanket is comprised of a tri-layer configuration of: a) a water tight liner to prevent water damage to the covered item, b) the wettable polymer, and c) a protective outer coat of a material such as glass fiber, kevlar and the like.

Abstract: The dual-fuel nozzle for a gas turbine and combustor includes a liquid fuel nozzle surrounded by a gas fuel nozzle. A converging sleeve surrounds the converging outer wall of the combined liquid fuel and gaseous nozzle to form a duct of decreasing cross-sectional area in a downstream direction whereby air flow through the duct accelerates toward the conical droplet spray pattern emerging from the liquid fuel nozzle. An inside swirler is located upstream of the liquid fuel tip to swirl the air flowing through the duct. An outer swirler is provided about the downstream end of the sleeve, likewise to swirl air. The accelerated swirling air flow through the duct and outer swirling air flow preclude impingement of oil spray droplets onto metal surfaces of the nozzle and hence prevent carbon deposition thereon which would otherwise be deleterious to the liquid fuel and gaseous nozzles.

Abstract: A spa jet comprising a first nozzle, a second nozzle, and an aeration chamber therebetween, are all disposed in a housing. One seal forms a watertight seal between the first nozzle and the housing, and another seal forms a watertight seal between the second nozzle and the housing. A ring is affixed to the second-nozzle downstream end, and a third nozzle is pivotally mounted in the ring. A retainer is mounted to the ring and it frictionally secures the third nozzle in any one of a continuum of angular positions. The ring can be a ball-bearing ring, whereby the third nozzle can freely rotate in the ball-bearing ring under the force of a water stream exiting the third nozzle. A non-circular opening in the third nozzle assists in rotating the third nozzle even when centered in the ring. A barrel, comprising the first and second nozzles and the aeration chamber, has latching tabs formed thereon, and the housing has a retaining profile formed therein for engaging the latching tabs.

Abstract: The object of the present invention is a liquid atomization procedure that uses appropriate geometric parameters and physical properties to ensure that the liquid to be atomized is discharged as a continuous, steady capillary microjet through a suitable orifice. The procedure relies on the microwithdrawal effect undergone by a liquid-gas interface when the gas is withdrawn from a point (orifice) near the liquid surface. The invented procedure is applicable to any mechanism involving homogeneous atomization of liquids (particularly electronic fuel injection).
