A portable parts washer flows a washing agent over an object to remove any contaminants. The washing agent and contaminants flow into a basin mounted below the object. The washing agent is drawn from the basin and used to wash the object to provide a closed-loop system. A venturi-type injector mixes ozone from an ozone generator with the washing agent. A pump draws the washing agent from a first inlet to the basin, forces the washing agent through the injector, and returns the washing agent thro...

A substrate treatment method including the steps of: generating droplets of a treatment liquid by mixing the treatment liquid with a gas; and causing the treatment liquid droplets generated in the liquid droplet generating step to impinge on a surface of a substrate being treated. The treatment liquid droplets have a volume median diameter of 5 .mu.m to 40 .mu.m.

The present invention describes a method and device for cleaning the components of an internal combustion engine. The device provides a single valve for regulating the flow and blend of air and cleaning fluid entering the combustion chamber of an internal combustion engine. The invention provides a novel device and process for cleaning mineral deposits from the surface of the combustion chamber, piston crown and intake ports, intake valves. The flow control valve is capable of regulating the flo...

The cleaning of barrel type containers, particularly beer kegs which have a fitting including a riser pipe which extends into the keg, is accomplished by incrementally increasing the level of a cleaning liquid which has been introduced into the barrel and, between each step of injection of cleaning fluid, causing turbulent motion of the liquid in the barrel by means of the injection of preselected volumes of a gaseous medium at a point below the surface level of the liquid cleaning fluid.

An aqueous oxidizing acidic cleaning solution or an aqueous oxidizing alkaline cleaning solution is produced by mixing an acidic or alkaline solution with ozone water. An aqueous reducing acidic cleaning solution or an aqueous reducing alkaline cleaning solution is produced by mixing an acidic or alkaline solution with hydrogen water. Each of these aqueous cleaning solutions has effective cleaning power and the ORP and pH values thereof are separately controlled. Therefore, by selecting an appro...

An apparatus and method for cleaning the intake system of an internal combustion engine, such as an automobile engine, employs intake manifold vacuum of the running engine to ingest and atomize a liquid cleaner using a bleed of ambient air. Atomizing of the liquid cleaner provides better dispersion of the cleaner to surfaces of the intake system of the engine, and prevents puddling of the liquid in low spots of the intake system.

Surface cleaning, chemical treatment and drying of semiconductor substrates is carried out using foam as a medium instead of a condensed phase liquid medium. In cleaning and chemical treatment, by introducing a foam into an overflow vessel the foam is caused to pass over the substrate in moving contact therewith. Drying of the substrate is carried out, using a water solution of carbon dioxide in a pressurizable vessel. By releasing the pressure in the vessel, a layer of foam is established on th...

A narrow neck bottle is washed and rinsed by a method comprising the steps of supporting the bottle in an upside down position, injecting water containing air bubbles, into the bottle through a tube extending through the narrow neck of the bottle, accumulating air released from the poured water in an upper space in the bottle and expelling air and water remaining in the bottle by the accumulated air. Apparatus for carrying out this method comprises an aspirator installed such that its discharge ...

An engine decarbonizing system comprises a manifold with one central and four lateral bores. Pressurized air and decarbonizing fluid in separate containers are adapted to be co-mingled and fed to and through the manifold. A tube assembly has an output tube and two parallel input tubes operatively coupled. The output tube is coupled to the central bore and the two parallel input tubes are coupled to the containers for dispensing pressurized decarbonizing fluid. Four short tubes are coupled to the...
