Abstract: Biofilm and debris can be removed from the interior and exterior surfaces of small bore tubing by passing an aqueous cleaning solution of water, one or more surfactants and preferably a source of hydrogen peroxide, optionally including small inert solid particles, together with a gas under pressure, to create a turbulent flow within the tubing that loosens the biofilm and debris so that they can be flushed from the tubing. When the exterior surfaces of tubing are to be cleaned, the tubing is inserted in a sleeve fitted with an adaptor that provides a pressure-tight seal between the tubing and the sleeve.

Abstract: A flushing system includes a tank for receiving a cleaning material, an object coupled to the tank for receiving the cleaning material from the tank, a container coupled to the object for receiving the cleaning material from the object, and a pressurized air supplying device for supplying a pressurized air into the tank to force the cleaning material into the object to clean the object. A control valve and a switch valve are coupled between the tank and the pressurized air supplying device and the container for selectively supplying the pressurized air into the tank and the container.

Abstract: This invention overcomes the disadvantage of the prior systems and produces a high velocity specially formed and constituted pressure aerodynamic stream system for efficiently and effectively removing ice from an aircraft. The specially formed stream system includes a stream within a stream, wherein a deicing fluid such a glycol is entrained within and encased by a surrounding jacket of entraining fluid such as air. This deicing is now known as coaxial stream/stream within a stream deicing. The special nozzle allows the stream to maintain fluid separation over its flight path so that aircraft contact is made by to be known as coaxial stream/stream within a stream deicing. The coaxial stream/stream within a stream deicing is further enhanced by pressurizing the stream to deliver the stream as a high pressure, high velocity stream to improve the aerodynamic sweeping action of the airstream.

Abstract: A chemical foaming system for use in a floor cleaning machine has a foam generator and a delivery system upstream of the foam generator in communication with a source of pressurized fluid and a source of liquid cleaning solution. The delivery system delivers pressurized fluid and liquid cleaning solution to the foam generator. A dispensing system is disposed downstream of the foam generator for dispensing foam generated by the foam generator onto the floor being cleaned. The foam generator has a pair of independent foaming chambers in generally parallel flow relationship intermediate the delivery system and the dispensing system whereby a portion of pressurized fluid and liquid cleaning solution delivered to the foam generator by the delivery system flows into one of the foaming chambers. The remaining portion of the pressurized fluid and liquid cleaning solution delivered to the foam generator flows into the other foaming chamber.

Abstract: A spherical object transport apparatus of the invention brings a spiral stream into contact with a first atmosphere containing a spherical object, selectively sucks the first atmosphere outward so as to engulf in the spiral stream for diffusing the first atmosphere outward, guides the spherical object so that the spherical object passes through the center of the transport apparatus, supplies a second atmosphere to the spherical object, and sends the spherical object together with the second atmosphere to the following step.

Abstract: Method and apparatus for cleaning and/or drying objects that may have been wetted or contaminated in a manufacturing process. The objects are submerged in a rinse liquid in an enclosed chamber, and aerosol particles from a selected liquid are introduced into the chamber above the rinse liquid surface, forming a thin film on this surface. As the rinse liquid is slowly drained, some aerosol particles settle onto the exposed surfaces of the objects, and displace and remove rinse liquid residues from the exposed surfaces by a “chemical squeegeeing” effect. Surface contaminants are also removed by this process. Chamber pressure is maintained at or near the external environment pressure as the rinse liquid is drained from the chamber. Inert gas flow is employed to provide aerosol particles of smaller size and/or with greater dispersion within the chamber. Continuous filtering and shunt filtering are employed to remove most contaminants from the selected liquid.

Abstract: Organic matter and metal impurities present on the surface of a photomask are removed. Foreign matter still adhering to the surface of the photomask is removed with H2 gas dissolved water. The photomask is dried. Thus provided is a method of washing a photomask in a manner which permits attaining an effect of removing foreign matter equivalent or superior to that of a conventional method with a small amount of chemical solution and reducing the amounts of chemicals and high purity water.

Abstract: An aerosol assisted chemical cleaning method to remove wall deposition from reaction chambers is provided. The method generates cleaning chemicals in an aerosol state, and then feeds them into the reaction chamber by a carrier gas. The cleaning chemicals interact quickly with unwanted deposits on all internal surfaces of the reaction chamber. By controlling the pressure in the closed reaction chamber, the deposits can be stripped off from the wall and fall into a waste acid collector. The acid collector can then process the waste to prevent contamination.

Abstract: Outlets of a contraction/enlargement exhaust nozzle type are formed in an air bubble-generating plate from which fine air bubbles are generated. The outlets are constituted with outer outlets and inner outlets. The outer outlets are formed along edge portions of the air bubble-generating plate and the inner outlets are formed in the inner portions of the air bubble-generating plate. Each of the outlets has a flow-in portion, a contraction portion, and a flow-out portion which are aligned in a coaxial line and have different diameters, so that each of the outlets are formed in a shape of a contraction/enlargement exhaust nozzle type. A diameter of the flow-out portion is smaller than a diameter of the flow-in portion, but larger than a diameter of the contraction portion. A height of the contraction portion is larger than a height of the flow-out portion, but smaller than a height of the flow-in portion.
