Abstract: An electrically non-insulative, typically metal, atomizer bell is housed in a shroud-like housing. A prime mover, such as an air turbine motor, typically also housed in the housing, rotates the bell to atomize coating material delivered to the bell. A second shroud movable relative to the bell has a first, retracted orientation in which the second shroud does not shield the charging portion from the approach of articles to the bell and a second, projected orientation in which the second shroud does shield the bell from the approach of articles to reduce the likelihood of disruptive electrical discharges from the bell.

Abstract: A high pressure fuel injector has a swirl generator with a metering disk upstream of the valve seat. The disks function to redirect the axially flowing fuel through the injector into a tangential fuel flow. As the fuel moves past the needle valve and the valve seat, the narrow cross section imparts a higher velocity to the fuel to atomize the fuel. As the fuel leaves the swirl generator and is ejected from the injector, the fuel forms a hollow conical sheet containing atomized fuel.

Abstract: A dripline duct with internally attached emitters is provided for irrigation. The duct is preferably plastic and continuous but does not have a constant cross-section along its length. The emitter may be auto-adjusting for securing a constant supply at a particular area of water pressures. The emitters are placed in the interior of the duct at its production phase and are covered almost totally by the wall of the duct which is swollen at the location of the emitters.

Abstract: An fire protection system for use in shipboard magazines wherein electric at detectors in a ship magazine provide temperature data to a fire panel. Upon detection of predetermined threshold temperatures, the fire panel initiates an alarm system and activates a fire sprinkler valve to apply water to fire sprinklers in the magazine. Temperature data from the heat sensors and stored weapon response data are used by a damage control system to generate graphic display data showing thermal conditions in the magazine and estimated times and temperatures at which stored munitions will undergo thermal destruction.

Abstract: A method and apparatus for droplet generation in agricultural or other spraying comprises supplying air and liquid to a supply chamber having an outlet opening, and entraining the liquid in the air flow for droplet formation. Air and liquid are injected into the supply chamber which has a closed end target wall toward which the liquid is directed in the form of a jet and from which the liquid moves outwards towards the outlet opening for droplet formation. The supply of air and liquid at suitable pressures to the chamber and so that the liquid proceeds with direction change to the outlet causes the droplets formed to have a size particularly suitable for effective coating of plant material, and the momentum provided to the droplets by the air enables controlled direction of the resulting spray mist even at very low liquid volumes per hectare.

Abstract: The invention is directed to a humidifying device which can be coupled to a conventional water feed pipe and shower head. The device includes a main body having a flow path, a diverter valve provided within the main body, the valve having at least two flow passageways therethrough, and a spray nozzle capable of being in fluid communication with one of the flow passageways of the diverter valve. The diverter valve can be placed in one of two positions, the position of the valve determining the flow path of water from the feed pipe. In the first position, water flows from the feed pipe, through the main body, and out the shower head. In the second position, the water flows from the feed pipe, through the main body and out the spray nozzle. The spray nozzle is capable of atomizing fluid flowing therefrom, thereby humidifying the air in a space.

In addition, a scavenge circuit is provided to direct a scavenging flow of fuel and combustion gas from the injector directly to the low pressure drain without communication with the spring chamber.

Abstract: A rotary nozzle for a high-pressure cleaning apparatus has a housing into which a feed line for a cleaning fluid issues, an outlet provided in the housing for expelling the cleaning fluid, a nozzle body through which the cleaning fluid flows, and a bearing that surrounds the outlet. The nozzle body is disposed in the housing, and is supported at its convex end in the bearing. The bearing is formed directly in an inner wall of the housing as a conically-shaped depression to avoid the need for a separate bearing insert, thereby simplifying the manufacturing process. Additionally, the conical shape of the bearing cooperates with the convex shape of the nozzle body to provide optimal sealing with a reduced contact surface for a long service life. The bearing is disposed concentrically relatively to the outlet. The nozzle body is set by the flow of cleaning fluid through the housing in a revolving movement in which a longitudinal axis of the nozzle body revolves on a generated cone.

Abstract: A fuel injector to inject fuel into a cylinder of an internal combustion engine when installed therein. The injector has an injector body which defines an interior cavity, a movable needle valve which cooperates with the interior body to define a variable-volume control chamber and a control valve for selectively blocking and permitting fluid communication among the control chamber, the high-pressure fuel supply, and the low-pressure fuel return. Such selectively controlled variation of the volume of the control chamber varies the position of the needle valve to selectively permit or prevent fluid communication between the high-pressure fuel supply and the engine cylinder. The control valve for selectively permitting fluid communication is preferably force balanced by relatively low forces acting thereon.
