Abstract: A method and apparatus are provided for atomizing liquids into a gaseous medium, in a fine, highly consistent, uniform dispersion. This pneumatic nebulizer method is designed to allow a wide range of liquids to be atomized without plugging. The process atomizes liquids directly from the surface of a body of liquid, allowing non-wetting materials to be used for the nebulizer. The liquid path does not require a narrowing of diameter at the exit area, nor along the length of the system, which minimizes plugging. The gas orifice is on or near the edge of the liquid path and may be very much smaller than the liquid path's area. The nebulizer has no suction. The liquid flow is controlled by pumping the liquid to the nebulizer. Most pneumatic nebulizer systems rely on the gas flow surrounding the liquid path, the liquid path surrounding the gas flow, or the gas flow being at right angles to the liquid flow.

Abstract: A nozzle holder, carrying at least one inlet nozzle is mounted within the bore of a hollow body between a liquid inlet and abutment.The or each inlet nozzle is dimensioned and arranged so that the radial cross-section of the flow of liquid through a mixing chamber between the nozzle holder and outlet (16, 17) at the other end of the bore from the liquid inlet is smaller than the cross-section of the mixing chamber.Particulate abrasive material is therefore sucked into the mixing chamber, where it mixes with the liquid, through passages which extend through the hollow body along axes which are convergent with the axis of liquid flow through the mixing chamber.

Abstract: A hose-end valve device to control the flow of water from a garden hose and liquid from an attached pressurized container with a single motion. The control device includes a camming ring rotatably mounted on an extension of a hose coupling. Rotational movement of the camming ring with respect to a tubular member which is attached to an actuator panel causes axially interacting camming surfaces to change the relative axial positions of the ring and tubular member thereby opening or closing an axially movable water flow valve, depending on the direction of rotation. Rotational movement of the camming ring with respect to a fixed frame opening causes radially interacting camming surfaces to move the actuator panel radially which depresses or raises the valve stem of the pressurized container. A preferred axially movable valve is an accordion-like self-closing washer-valve.
