Abstract: A high pressure hot water acid washer is towed to a site on a trailer. A chemical tank and gasoline and diesel fuel tanks are filled. A water supply hose is connected to a water tank. A power cord is connected to a power source. A float valve controls the filling of the water tank. Water flows from the water tank through a Y-type filter to a water pump. A drain withdraws water directly from the water pump. The water pump and a compressor are driven with an engine. Pressurized water flows through a flow switch to a heat exchanger. Upon water flow, the flow switch completes a power circuit to operate a fuel pump with an electric motor. Fuel is pumped from the fuel tank and is atomized and sprayed into the heat exchanger. An ignition coil ignites the fuel. The power circuit is interrupted upon sensing a high temperature in a pressurized water delivery line from the heat exchanger. Pressure of pressurized hot water in the delivery line is controlled with a hot water pressure relief valve.

Abstract: A spraying apparatus adapted for blending liquids in a gaseous spray stream includes a gas nozzle that is adapted for discharging a gas jet to be directed at an object to be sprayed, and a plurality of liquid nozzles having suction outlets adapted for removal of liquid therefrom by aspiration, the liquid nozzles being mounted for disposing them relative to the gas jet to effect aspiration of liquid from their outlets together into the gas jet for spraying an object with the resulting spray mixture, at least one of the gas nozzle and a liquid nozzle being mounted for varying the disposition of the liquid nozzle relative to the gas jet to thereby vary the rate of aspiration from the outlet of such liquid nozzle relative to the rate of aspiration from the outlet of another liquid nozzle.

Abstract: A process and apparatus are provided for injecting dry lightweight particulate material into a stream of catalyzed resin. The dry lightweight particulate material is stored in a fluidizing tank. The fluidized dry particles are conveyed from the tank under a controlled vacuum created by a low pressure venturi pump. An anti-static conveying tube delivers the dry lightweight particulate material to an adjustable delivery tube which terminates with a nozzle. The nozzle delivers a low velocity controlled spray pattern which coincides with the stream of pressurized resin. The nozzle is positioned at an acute angle relative to the longitudinal axis of the resin stream and injects the dry lightweight particulate material into the stream. Within the venturi pump and opposite to the main low pressure, low volume inlet, is a second pressurized inlet. This inlet directly controls the degree of vacuum, thereby precisely determining the amount of dry lightweight particles delivered to the resin stream.

A common pressure plate is fitted over the push button valve of the containers and a single key is used for actuating the push button valves. Each valve is directed on an axis towards a common point so as to create a fog or cloud containing insecticide and/or fungicide.

Abstract: A dispenser (1) has two facing and outwardly sealed reservoirs (2) for separate media components, as well as for each reservoir (2) a separate discharge pump (3), both discharge pumps (3) being simultaneously operable by means of a common handle (10). Thus, the components are separately sucked in and are kept separate up to a mixing zone located inside or outside the handle (10), but with respect to the use thereof are brought together at the latest possible time. The components can be brought together in a precisely dosed quantity ratio.

Abstract: An external mix, air-assisted, airless atomization, plural component spraying system and method includes a first source of a first component, e.g., a resin; a second source of a second component, e.g., catalyst for the resin; spraying means to mix the resin and catalyst and direct the mixture to a substrate; a source of compressed air; and means for injecting the catalyst into the compressed air. The spraying means includes a nozzle assembly which comprises a liquid nozzle for forming the resin into a fan-like film with expanding edges extending from a liquid orifice, and a nozzle assembly for directing a flow of compressed air and catalyst at the fan-like film colsely adjacent the liquid orifice. In a preferred embodiment, compressed air is directed to impinge upon the expanding edges of the fan-like resin stream downstream of the impingement of the flow of compressed air and catalyst particles to capture from catalyst particles in small, uniform spray pattern.

Abstract: A fluid gun has multiple spring-loaded oblong extendable barrels arranged to provide a plurality of fluid streams which intersect in air at a predetermined distance from the nozzles when a single trigger is squeezed. The gun has separate chambers containing fluids of different colors. When the streams intersect, the colors combine and mix.

Abstract: A hospital room humidification system operated from an outside source of pressurized oxygen and/or other gas for increasing the humidity of the ambient air in the room. The humidification system includes a collapsible bag for containing a quantity of water in a condition sealed from the environment of the room, an atomizing nozzle formed with separate liquid and gas passageways, a first adapter for coupling the atomizing nozzle to the water containing bag, and a second adapter for selectively coupling the atomizing nozzle to the outside pressurized gas source. The atomizing nozzle is operable for causing the pressurized gas flow discharging from the air passageway to break the flow of liquid discharging from the liquid passageway into fine liquid particles and to directly dispense such particles into the air of the room in the form of a mist and in a manner which significantly increases the humidity of the ambient air in the room.

Abstract: A method and apparatus for simultaneously applying and blending pigmented cosmetics is one step, wherein pressurized air is released from a container, is divided into one or more spray channels, and exits together with pigmented cosmetics through a directional shield onto an individual's skin. The pigmented cosmetics are mixed with the pressurized air by various means. In a preferred embodiment of the apparatus, a part or the entire directional shield can be removed, enabling changes in the size and shape of the area of skin where the pigmented cosmetics are deposited. For some embodiments of the apparatus, the colors and types of cosmetics used can be varied by switching interchangeable cartridges or canisters of cosmetics.

Abstract: A spray head for use with a liquid to be sprayed and a propellant. The spray head includes a first cap which has segmented, arcuate, resilient, annular gripping sections having outwardly extending projections which grip an annular lip on the container of propellant. A cover on the first cap is shaped and adapted to coact with a dome on the first container so that a section of the spray head is placed under compression or tension by opposing forces when the spray head is attempted to be removed from the container of the propellant. A second cap has a body with threads to connect it to a second container which would normally contain a liquid. A bridge included in the second cap is operatively attached to the first cap. The bridge includes a channel through it and has ne end connecting an opening in the first cap. An actuator on the bridge controls a spring-biased valve n the propellant container. The other end of the channel and bridge is in close proximity to a bore in the second cap.
