Abstract: An improved oscillating sprinkler comprising a frame having a sprinkler tube mounted for oscillating movement on the frame. An inlet water housing is mounted on the frame and supplies water to the sprinkler tube. The sprinkler tube is driven in an oscillating path by a crank arm, and an eccentric gear mechanism driven by the water being supplied to the sprinkler tube is operably connected to the crank arm. The eccentric gear mechanism is constructed to provide a variable speed output that balances the varible speed output of the crank arm to provide a substantially uniform velocity of oscillating movement for the sprinkler tube. The sprinkler also includes a mechanism for varying the effective length of the crank arm to change the arc of oscillation of the sprinkler tube, and a slip clutch mechanism interconnects the inner end of the sprinkler tube to the housing to permit the sprinkler tube to be manually rotated to shift the spray pattern to one side or the other.

Abstract: A yaw and pitch thrust vectoring exhaust nozzle includes a spherical collar, and two surrounding clam shells hinged to a gimbal ring and pivotal about an axis perpendicular to the clam shell hinge axis. The clam shells define a variable area nozzle throat (42) which can be selectively directed vertically by rotation of the clam shells about the hinge axis (38), or horizontally by rotation of the clam shells and gimbal ring about the pivot axis (30), thereby biasing the nozzle exhaust flow vector. Divergent flaps (44, 46) further direct the exhaust downstream of the nozzle throat (42).

Abstract: A method for the fabrication of a continuous action reservoir type air freshening device is described. The device is characterized by the use of an evaporation rate controlling porous membrane which is in intimate contact and completely covers the exposed surface of an erodible gel-type of solid perfume composition. The fragranced gel is enclosed in a container, one end of which is open and over which is affixed the porous membrane. One side of this membrane is exposed to the atmosphere; the other side intimately contacts the solid reservoir consisting of the fragrance gel. Transmission of the volatile fragrance and carrier agents to the surrounding environment through the porous membrane matrix occurs as a function of an evaporative process. The membrane permits only a limited penetration, if any by the gel solution, i.e. in the liquid state, but is sufficiently permeable to the gel solution to establish physical attachment between the solidified gel and the membrane.

Abstract: Disclosed is an aerosol actuator button for delivering a product such as an atomized air freshener liquid from a pressurized aerosol container wherein the spray pattern produced is tilted away from the central long axis of the actuator button and container. Tilting of the spray pattern is accomplished by placing the actuator button orifice at the bottom of an asymmetrical conical depression which is open to the surrounding atmosphere. More preferably, the orifice itself is asymmetrical with the shorter portion of the orifice being situated relative to the conical depression such that tilting of the spray is accentuated. This configuration causes the atomized spray to be tilted away from the central long axis in spite of the fact that the orifice is concentric with the central long axis of the actuator button. Also disclosed are dies for making such actuator buttons.

Abstract: NOx production from pressure-atomised burners is reducible by shaping, e.g. splitting, the fuel film leaving the burner. This is achieved, in accordance with the invention, by having an external wall 54 which surrounds the fuel outlet orifice 52 and from which external formations 56 extend radially inwardly towards the axis 20 of the burner. The formations 56 penetrate the frusto-conical pattern of fuel (not shown) emitting from the orifice 52 to split the flame into four discrete lobes. Other arrangements are possible in which different numbers of lobes are formed; or assymetric patterns are produced; or shaped flame patterns having no discrete lobes are produced.

Abstract: Equipment for spraying a fluid such as a herbicide comprises a support tube on which is mounted a head comprising a body and a rotatable disc. Electrical supply leads and a supply hose for fluid pass to the head through the support tube. The head and the body define between them a narrow annular gap. Fluid is supplied to the disc at a position radially inwards of the gap and flows through the gap to be discharged as fine droplets from the periphery of the disc. The width of the gap is such that the fluid passing through it is wiped circumferentially so that it is distributed around the disc. This promotes an even spray of fluid from all parts of the periphery of the disc. Special shapes for the disc are proposed in order to promote the formation of small droplets of uniform size.

Abstract: A gun head constituting the front section of an electrostatic powder painting gun makes the pattern of powder flow spouted out therefrom into the form of a flat fan-like shape to decrease the velocity of the powder flow traveling toward a workpiece to be painted to thereby enhance the efficiency of adhesion of the powder paint to the workpiece. A spout section of an end wall of a cylindrical body constituting a fundamental section of the gun head has a pair of opposed slits bored therein such that the spacing between these slits decreases progressively as approaching the outer ends thereof, and the inner ends of these slits communicate with a powder path formed inside the cylindrical body at opposed spots close to the inner surface of the powder path.
