Abstract: A batch-type warewash machine includes a chamber for receiving wares to be cleaned, the chamber having a chamber access opening and a single spray zone, with at least one spray system for spraying liquid onto wares in the single spray zone. A door is movable between a closed position covering the chamber access opening and an open position away from the chamber access opening to allow wares to be moved in and out of the chamber. A curtain structure is mounted on the machine, the curtain structure located behind the door when the door is in the closed position. The curtain structure remains in position and at least partially covers the chamber access opening when the door is in the open position so as to retain hot moist air within the chamber when the door is moved to the open position upon completion of a ware cleaning cycle.

Abstract: A tank washer comprising a housing which supports reciprocating spray nozzles for spaying the walls of a tank which is to be cleaned with a cleaning liquid. The reciprocation of the spray nozzles is controlled by a piston that reciprocates in the housing under the force of the cleaning liquid. A piston assembly for use in a tank washer comprising a piston head and a connecting rod having one end connected to said piston head. The piston is mounted in a piston chamber for reciprocation.

Abstract: A device for clearing obstructions from a medical tube, such as a chest tube, is disclosed in various embodiments. The device features a shuttle member that is magnetically coupled to a guide wire within a guide tube, through the guide-tube wall, so that translation of the shuttle member induces a corresponding translation of the guide wire within the guide tube, without penetrating or compromising the guide-tube wall. In this manner, when the guide tube is coupled to a medical tube where obstructions have formed, the guide wire and clearance member may be inserted into and withdrawn from the medical tube, via actuation of the shuttle member, to engage and help clear such obstructions from the medical tube without compromising the sterile field. Methods of clearing a medical tube of obstructions are also disclosed.

Abstract: A fixture for holding a valve assembly in an automated washing system, wherein the valve assembly is movable between an opened position and a normally closed position. The fixture is comprised of first and second housing sections that are releaseably attachable to each other. The housing sections define an internal cavity that is dimensioned to hold the valve assembly in an opened position. A fluid inlet is in communication with the chamber, and is attachable to a source of an anti-microbial fluid in the washing system. A fluid outlet communicates with the chamber to allow the anti-microbial fluid to exit the fixture.

Abstract: A container rinsing apparatus and method of rinsing a container that includes a nozzle positioned to spray liquid at a particular spray angle toward the interior surface of the container when the top surface of the container depresses a base cover of the rinsing apparatus. The rinsing apparatus is capable of completely rinsing virtually any shape of container without requiring manipulation of the container relative to the rinsing device during rinsing. When the container is positioned to engage the rinsing apparatus, the nozzle is closer to the open end of the container than the closed end.

Abstract: An apparatus for cleaning a semiconductor substrate has a chuck for rotatably supporting the semiconductor substrate, and a horizontally movable probe for applying ultrasonic vibrations uniformly to cleaning solution supplied onto an upper surface of the semiconductor substrate. The probe makes contact with the cleaning solution supplied and extends vertically from the upper surface of the substrate. The cross-sectional area of the probe gradually increases in a direction towards the semiconductor substrate so that the ultrasonic vibrations are widely distributed to the cleaning solution. The lower surface of the probe has surface features that act to disperse a reflected wavefront of the vibrational energy. Thus, patterns formed on the semiconductor substrate will not be damaged by the ultrasonic vibrations.

Abstract: The present invention relates to apparatus for washing drains. The apparatus includes a support and a nozzle, which are adapted and configured to convey fluid to and to wash a drain. Typically, the apparatus includes a wand as the support and a ball or head as the nozzle. The apparatus can also include a fluid retainer, which can keep the dispensed fluid in and/or near the drain.

Abstract: A single wafer cleaning apparatus that includes a rotatable bracket that can hold and rotate a wafer and that also includes a UV light tube capable of being positioned parallel to, and a short distance from, a wafer top surface to radiate oxygen above the wafer top surface with UV light rays to produce ozone.

Abstract: A cleaning apparatus for removing contaminants from the surface of a substrate includes two parts: one which produces an aerosol including frozen particles and directs the aerosol onto the surface of the substrate to remove contaminants from the surface by physical force, and another part in which a fluid including a gaseous reactant is directed onto the surface of the substrate while the surface is irradiated to cause a chemical reaction between the reactant and organic contaminants on the surface, to chemically removing the organic contaminants. In the method of cleaning the substrate, the physical and chemical cleaning processes are carried out in a separate manner from one another so that the frozen particles of the aerosol are not exposed to the effects of the light used in irradiating the surface of the substrate. Therefore, the effectiveness of the aerosol in cleaning the substrate is maximized.

Abstract: In a glass washing machine having a glass carrier rotatable on an upright axis, half of the carrier is always in an access zone where glasses can be loaded onto the carrier and removed from it, the other half in a cleansing zone where detergent solution is discharged from a first set of spray nozzles and germicidal rinsing solution is discharged from a second set of nozzles. Upon actuation of a pushbutton switch, the carrier rotates through 180.degree., always in the same direction, then stops until the switch is again actuatd. Liquids are discharged from all nozzles while the carrier rotates. Detergent solution is recirculated, but fresh detergent solution is introduced during a predetermined portion of each period of carrier rotation.

Abstract: Apparatus for selectively coupling a source of pressurized fluid to washing machine containers which hold items during wash cycles where there are first containers adapted for preventing the flow of fluid and second containers adapted for receiving the fluid when the containers are placed in their normal positions in the washing machine. The apparatus includes a member having a contoured passage therethrough and which defines an inlet and an outlet and means slidably disposed within the member for controlling the flow of fluid through the outlet to the containers. The flow control means has a first portion, which may include a body and a flange and a second portion which may be an elongate pin. The first portion is adapted for such engagement with the contours of the passage that the flow control means can assume a first position for preventing the flow and a second position for permitting the flow.

Abstract: A system for supplying treatment liquids to an electroplating drum rotatably mounted in trunnion bearings comprises at least two sets of ducts of different sizes opening into the electroplating drum and disposed in two series about a through bore of the bearing. An axially fluted inner surface of the through bore cooperates with a cylindrical outer surface of a removable cleaning tube to define one set of ducts. A liquid distribution valve allows treatment liquid to be supplied either to the two sets of ducts or to only one of the sets of ducts. Removal of the cleaning tube from the bearing allows overhaul of the one set of ducts.
