Abstract: The present invention provides a new wetting chamber for a metering and wetting system typically for polyelectrolyte polymer. Atmospheric air is used to disperse the polymer fed into the chamber by a suitable feeder and to generate air/water turbulence in the wetting chamber in which the polymer is wetted. Suction draws the metered polymer into the wetting chamber and increases the downward velocity of the polymer as it enters the turbulent section of the wetting chamber. When wetted, the polymer is transferred to a mixing tank for aging. It is then ready for use in various industries.

Abstract: A poultry vaccinator for use in brooding houses having multiple layered rows of cages for high volume vaccination. The vaccinator apparatus includes a plurality of atomizer nozzles disposed at multiple elevations on a collapsible stand pipe assembly.

Calibration orifices located in the liquid lines to each of the atomizer nozzles provide pressure compensation for elevational differences of the nozzles. Thereby producing a uniform particle size aerosol out of the nozzles regardless of nozzle elevation.

Abstract: An improved powder pump for pumping air entrained solid particulate powder material comprising a pneumatic conveyor line within which there is located a low pressure venturi pumping chamber. This venturi pumping chamber is intersected by a powder supply passage through which powder is drawn into the conveyor line. Located within the powder supply passage is a rotatable tubular powder diffuser through which the powder passes in the course of passage through the powder supply passage. Rotation of the diffuser is effected by atomizing or metering air flow to the powder flow passage upstream of the venturi pumping chamber. This atomizing air flow, in addition to effecting rotation of the diffuser, also controls the rate of flow of powder through the powder supply passage and into the venturi pumping chamber.

Abstract: A device for installation in the water supply pipe to a bath shower head comprising a venturi aspirator connected to a vented measuring chamber, said chamber connected to a supply container for liquid additive. Restricting the vent to the measuring chamber creates a pressure differential causing additive liquid to flow into said chamber. With the vent reopened, the liquid additive flows by gravity and differential pressure into the duct connected to the venturi aspirator, mixing the air and water flowing to the shower head and producing an aerated shower spray with liquid additive dispersed therein.

Abstract: A closure for use in dispensing a spray of liquid and air can be constructed so as to utilize a cap and a spout rotatably mounted on the cap so as to be capable of being moved between open and closed positions. An air-liquid mixing chamber is located within the spout adjacent to the discharge end of the spout and an orifice is provided on the discharge end of the spout so as to lead from the mixing chamber. A liquid passage and at least one gas passage are provided in the cap and in the spout for conveying liquid and gas into the mixing chamber.

Abstract: A spraying apparatus utilizes pressurized gas to spray liquid contained in a large replaceable or refillable cartridge. The cartridge is positioned within a casing which provides a pressure chamber, and a source of pressurized gas is attached to the casing to pressurize the chamber. The top of the cartridge communicates with the chamber so that the liquid is also pressurized. A tube extends from above the level of the liquid in the cartridge to the bottom of the cartridge and is attached to a valve. An opening is provided in the tube adjacent to the bottom of the cartridge, and the diameter of the tube is reduced above the opening to restrict the flow of gas through the tube and to create a pressure differential in the tube. When the valve is open, pressurized gas flows through the tube, and, since the pressure of the gas inside the tube at the opening is less than the pressure of the liquid, liquid flows through the opening, mixes with the gas within the tube, and flows through the valve.

Abstract: An improved nozzle apparatus rapidly convertible, while operating, between spray and foam forming modes of operation. An elongate rigid generally cylindrical first conduit member receives surfactant bearing solution at an inlet port thereof and directs the solution under pressure to a spray forming nozzle connected at an outlet port of the first conduit. A second elongate conduit member coaxially slidably overlies the first conduit member and is movable relative thereto between extended and retracted positions. When in its retracted position, the second conduit member exposes the spray-forming nozzle, which is then enabled to direct a spray pattern of the solution longitudinally outward from the apparatus. When in its extended position, the second conduit member encompasses the spray-forming nozzle, and aspirates the spray therefrom with air to form foam which is ejected longitudinally outward from the second conduit member.

Abstract: A foam generating unit is adjustably mounted for longitudinal movement on a liquid sprayer having an orifice which provides a diverging liquid stream directed into the inlet of the foam generating unit. The foam generating unit includes a foam-generating section most advantageously having a pressure-reducing inlet passageway section including a preferably sharply outwardly tapering portion leading to a throat portion. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. The desired foaming action is achieved by adjusting the points of the pressure-reducing passageway section struck by the stream by moving the foam generating unit relative to the orifice.

Abstract: A foam generating nozzle is made either as an attachment to an existing liquid spray nozzle unit or as a pre-manufactured assembly and includes a foam-generating section having a pressure-reducing passageway including a preferably sharply outwardly tapering portion leading to a venturi-forming throat portion, and adapted to receive the liquid stream issuing from an inlet orifice. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. Optimum foaming action is achieved by adjusting the point of the pressure-reducing passageway struck by the stream which is most advantageously achieved by adjusting the angle of the stream issuing from the orifice so the widest portion thereof strikes the end section of the tapering portion of the passageway.
