Abstract: An adjustable spray nozzle with adjustable arc of coverage as well as spray elevation angle and flow rate. A very simple adjustable arc of coverage spray nozzle configuration is also disclosed which may be easily assembled for a particular precipitation rate and/or range of coverage at a selected nominal pressure. Also disclosed is a simple fixed arc of coverage spray nozzle with selectable ranges for a particular precipitation rate.

Abstract: A flow control device for mounting on a plural component spray gun for controlling the flow of short segments of fiberglass, liquid or powder, into a fan spray pattern of mixed components ejected from a nozzle of the spray gun. An internal passage in the flow control device is provided with a pair of resilient, rectangular plate members movable between open and throttling positions, so as to precisely control the flow of material into the fan spray pattern emitted by the spray gun. The pair of resilient plates are movable by adjusting screws passing through threaded openings formed in opposed side walls of the flow control device.

Abstract: The uniform distribution of mixed phase fluid stream on to the top of a contact bed in a reactor chamber is provided by a horizontal tray with a plurality of spaced-apart, vertically disposed chimneys extending through the tray. These chimneys have a first end to receive liquid and gas above the tray and a second end for distributing the liquid and gas downwardly below the tray. Importantly, the second end is provided with a spray generating device located below the tray for producing a conical downward spray of the mixed fluid phase onto the top surface of a bed of contact material positioned below the tray. The spray generating devices for producing the conical spray are located at positions so that the spray of the mixed fluid stream from one spray generating device as it impinges on the top surface of the fixed bed, will overlap the spray from an adjacent spray generating device.

Abstract: The fuel injection nozzle has a nozzle body 11 with a movable fuel control valve 13. At the front end of the nozzle body 11 there is a spray tip 12 with the discharge orifices 16. The fuel jet disintegrator 17 is running through two opposite located discharge orifices 16. The ends 18 of the disintegrator 17 have a shape of a spring with outer diameter greater than a diameter of the discharge orifices 16. During the operation, fuel jet, coming from the discharge orifice 16, impinges on the disintegrator 17, breaks up into a multitude of tiny particles and produces spray which provides more complete burning of the fuel with the reduction in smoke and fuel consumption.

Abstract: A combination fuel introduction, distribution and air shaping device is provided for a fuel carburetion system of an internal combustion engine. The distributor is elongated and of generally inverted tear-drop cross-section. Fuel discharge openings are spaced longitudinally near or at the bottom of the distributor. The distributor extends across the intake air duct of an air-fuel mixing and modulating device that is adapted to deliver a mixture of finely divided fuel droplets in air to the intake manifold of an internal combustion engine. The body of the distributor divides the intake air flow into two converging air streams which entrain the fuel as liquid droplets sweeping it from a helically coiled wire extending along the downstream side of the distributor and uniformly distributing the droplets in the air streams.

Abstract: A nozzle for coupling a diverter to a hose for the purpose of changing the water stream from the hose into a spray by adjusting the position of the diverter. The nozzle is made out of plastic in one piece and may be connected to a conventional garden hose for selectively converting a solid stream of water into a uniformly distributed thin sheet.
