Abstract: A hose-end sprayer has a selectively rotatable rotary valve received within the transverse bore of a housing which includes a carrier liquid inlet passage, a chemical liquid inlet passage and a discharge passage. The valve has a carrier liquid duct and a chemical liquid duct opening into the carrier duct for interconnecting the inlet passage in a first rotative position of the valve, and the valve is capable of closing the inlet passages in a second rotative position of the valve. The rotary valve is selectively rotatable in a third position for interconnecting the liquid passage only with the discharge passage in a rinse position of the valve. Container venting is isolated from a valve chamber in which the rotary valve operates to avoid entry of carrier liquid into the container through the open vent in the ON position of the valve upon its selective rotation.

Abstract: A device for generating a pressurized stream of treating media including a vessel (4) containing the treating media (6), a pressurized fluid delivery assembly (16) for delivering a pressurized fluid to the vessel (4) and a conduit (14) for transporting the treating media (6) out of the vessel (4) which has been pressurized through the pressurized fluid.

Abstract: The foam marking device of the present invention includes a solution tank with a tube extending upwardly therein. An air line extends from an air pump and into the tank so as to provide air into the tube. The air passes through a porous element so as to create air bubbles. The tube includes an elongated slot that allows foam solution within the tank to enter the tube. The air bubbles generate foam within the upper end of the tube. The foam passes through a homogenizer at the upper end of the tube and then into a foam line for discharge onto the ground. The slot serves dual functions, by allowing solution in the tank to enter the tube and by allowing foam within the tube to enter the tank when the pressure in the foam discharge line exceeds the pressure within the tube.

Abstract: A self-adjusting, free-flowing pneumatic nebulizer interface is described for coupling fluid phase separation apparatus such as capillary electrophoresis apparatus or fluid-phase analyte delivery apparatus such as flow-injection analysis apparatus to gas phase, post-separation detection apparatus such as mass spectrometers, chemiluminescence detectors, or other similar gas phase detection apparatus. The interface combines the analytes with only the needed amount of sheath fluid to produce a combined flow whose magnitude automatically matches the self-aspiration rate of the pneumatic nebulizer interface, and which is combined with a gas flow to produce an aerosol. The resulting aerosol can then be either deposited directly on a surface, forwarded directly to a detection system or forwarded first to a conversion apparatus such as an oxidizer and the oxidized sample components are then forwarded to a detector.
