Abstract: An agricultural sprayer includes a spray boom equipped with a plurality of spray heads, with each head having a body defining a cavity located in fluid communication with a fluid inlet and an array of four outlets leading to four nozzles respectively having different flow rates. A nozzle-select control member is mounted for rotation in the cavity and includes a fluid passage arrangement for establishing fluid connections between the inlet and different ones or combinations of the four nozzles as the control member is rotated among preselected discrete positions by an electric stepper motor, with the stepper motor being controlled in response to vehicle speed so that the spray tip capacity decreases for effecting a constant application rate as the vehicle speed decreases from a maximum permitted speed.

Abstract: A regulating device for a water outflow, in particular of sanitary fittings, comprises a cylindrical sleeve with a central cylinder axis. The sleeve is adapted for attachment to or in the water outflow. A support plate is disposed perpendicular with respect to the axis of the sleeve. A throttling and regulating element can rotate relative to the support plate about the axis and can move in the direction of the axis. By way of the throttling and regulating element, water can flow through from one side of the support plate to the other side of the support plate. The throttling and regulating element comprises a device for fine throttling of the water. An annular distribution space for the water is delimited by the support plate, the sleeve and the throttling and regulating element. In the distribution space, water can flow in from openings in the throttling and regulating element. In the distribution space, water can flow out of the sleeve to a water outlet.

Abstract: Shower heads are disclosed providing for varying types of spray. One spray head permits two different spray patterns with one of the patterns optionally being pulsed or unpulsed. Another provides three different spray patterns, with two of the patterns having pulsing impellers which can pulse at different speeds from each other. The third provides three different spray patterns, each of which provides spray through outlets at different force levels.

Abstract: A pistol nozzle is constructed to include a body, a cap covered on the body, a spray-pattern disc and a spray-pattern dial fastened together and coupled to the cap, and a control ring for rotating the spray-pattern disc and the spray-pattern dial to control the spray pattern of water, the spray-pattern dial having a smoothly arched water hole disposed in communication with one water outlet of the spray-pattern disc for output of water from the body to produce a wide spray pattern of water.

Abstract: A brush and water spray system comprising, a primary head having a flat exterior section with apertures therethrough for dispensing water, a tubular interior section in a cylindrical configuration adapted to be coupled to a shower outlet tube for receiving water to be dispensed and a generally hemispherical intermediate section with a housing therewithin and a connector at the interiormost end of the inner section couplable to the shower outlet tube.

Abstract: A diffuser assembly for controlling air flow in a fresh food compartment of a refrigerator has a housing mounted to the refrigerator liner wall that covers a first air flow opening in the fresh food compartment liner. The housing has side walls and an exterior wall with a second air flow opening spaced from the liner by the side walls. An air flow passage extends between the first air flow opening and a second air flow opening The exterior wall has a first centralized opening passing therethrough and an inner surface with a recessed elongated slot. The assembly has an elongate leaf spring secured in the housing adjacent the inner surface along the recessed slot and biased away from the exterior wall. The spring has a second centralized opening aligned with the first centralized opening. The assembly has a dial diffuser with a shaft that extends through the first and second centralized openings and a shaft controlling portion extending beyond the exterior wall of the housing.

Abstract: The dispenser dispenses and spreads measured quantities of granular materials over a relatively wide area. A plurality of individual measurement chambers are distributed throughout a disc or rectilinear panel which is moved relative to other discs or panels with similarly shaped and spaced holes to first cover the inlet to the chambers to prevent unwanted leakage of material from the interior of the container, and to then open the outlet to each of the chambers to dispense material. A deflector is positioned below the dispenser outlets to spread the dispersed materials over an even wider area. The dispenser is used advantageously to spread seasonings and other food materials onto spread-out food items such as french fries and popcorn, large kettles and vats, etc.

Abstract: A turbulence-quelling fluid-flow controller and method having a housing with a fluid flow passageway and a vane member disposed in the passageway. Inclined surfaces extend on the member between the vanes, and the inclined surfaces and the vanes have the fluid flowing thereagainst and direct the flow to a nozzle, all for quelling turbulence in the flow. The method diverts the flow from the first path and into a second path, at a right angle to the first path, and between vanes, all for quelling.

Abstract: A liquid spray nozzle has an outer orificed plate portion with a generally elliptical orifice which tapers in the direction of the water stream and an inner orificed member which has a larger centrally located circular orifice and a pair of smaller circular orifices arranged symmetrically on either side of the central orifice. A centrally located tubular channel member is provided to carry the water stream from a hose or the like such that it passes through the inner and outer orificed members. Means are provided for rotating the orificed members relative to each other. In a first position where the smaller orifices of the inner plate are positioned opposite the corners of the elliptical orifice of the outer plate, a flat, fan-shaped spray is produced. When one of the orificed members is rotated to a position 90.degree. from this first-mentioned position whereat the smaller inner circular orifices are covered by the outer orificed plate, a high-force, narrow cylindrical water stream is provided.

Abstract: A fluid dispersal device utilizes the Karman Vortex street phenomenon to cyclically oscillate a fluid stream before issuing the stream in a desired flow pattern. A chamber includes an inlet and outlet with an obstacle or island disposed therebetween to establish the vortex street. The vortex street causes the stream to be cyclically swept transversely of its flow direction in a manner largely determined by the size and shape of the obstacle relative to the inlet and outlet, the spacing between the obstacle and the outlet, the outlet area, and the Reynolds number of the stream.
