Abstract: A lavatory pan washing apparatus includes a water supply unit supplying washing water into a rim so that a whirling flow is formed in a lavatory bowl, an air inlet pipe connected to a water discharge channel continuing to the downstream side of a water sealing portion of a pan, an air sucking unit sucking air through the pipe from the channel, and a control unit configured to activate the water supply unit at a time of washing of the pan so that the washing water is supplied into the water sealing portion. The control unit is configured to start activation of the air sucking unit after rise of a water level in the lavatory bowl, so that air is sucked through the pipe from the channel. The control unit is configured to deactivate the water supply unit after air has flowed through the air inlet pipe into the channel.

Abstract: A rotating and telescoping cleaning system improves high pressure water cleaning of the inner surfaces of vessels or tanks. Vessels can be vertically divided with dividing plates with centered through-holes. Synchronized and controlled transverse and rotary movements of water jets result in a controlled spiral or helical cleaning track along the vessel walls. The water jets are directed at a pre-adjusted distance from the vessel wall and the travel speed of the water nozzle jets is exactly controlled allowing the removal of very hard deposits. One pass with the tool carrier with operating water jets along the length axis of the vessel results in a thoroughly cleaned vessel wall. The tool unfolds and folds inside of the vessel powered by the flow of the high pressure cleaning water.

Abstract: A wafer processing system has a moveable drain assembly having multiple drain rings. The drain rings may be spaced apart sufficiently to allow a process fluid applicator to move between them. Each drain ring provides a separate drain path, optionally in a separate recirculation loop carrying a single process fluid. The drain rings may be sequentially moved into position to collect process fluid moving off of the workpiece. As a result, process fluids may be more uniformly applied and used process fluids can be separately removed, collected, and either recycled or processed for disposal. Mixing of used process fluids is largely avoided. A lower process fluid outlet allows for processing the back side of the wafer as well, without flipping the wafer.

Abstract: A lift mechanism for a cleaning device of a dry shaving apparatus includes a base plate with guides and a chassis plate mounting the chassis and arranged for displacement relative to the base plate. Coiled-strip springs arranged on the guides spring-load the chassis plate against the base plate. On actuation of the lift mechanism the coiled-strip springs are untensioned by coiling up along the guides, thereby lifting the chassis plate. The coiled-strip springs reduce the load on the construction and ensure an almost noiseless lift mechanism.

Abstract: A method for cleaning a semiconductor substrate is provided. The method initiates with introducing a liquid onto the top surface of the semiconductor substrate. Then, a bottom surface of a resonator is coupled to a top surface of a semiconductor substrate through the liquid. Next, sonic energy is transmitted through the resonator to the liquid. Then, the liquid is heated through the bottom surface of the resonator. A method for applying localized heating to a cleaning chemistry during a cleaning operation of a semiconductor substrate is also provided. The method initiates with positioning a resonator to contact a surface of a cleaning chemistry applied to a semiconductor substrate. Then, heat energy is simultaneously applied with the sonic energy through the resonator to clean the semiconductor substrate. A device for cleaning a semiconductor substrate and system for cleaning a semiconductor substrate are also provided.

Abstract: A method for precision cleaning of a workpiece with a cleaning fluid comprising liquid and/or supercritical fluid carbon dioxide and a primary solvent which is liquid at ambient temperatures and pressures comprises first placing the workpiece in a pressurizable vessel with a removable lid and within an inner tank open at the top; supplying the primary solvent to the inner tank; flushing the primary solvent through the pressure vessel; draining the inner tank to remove the primary solvent; and then supplying liquid and/or supercritical fluid carbon dioxide to the pressure vessel and flushing it through the vessel by withdrawing it from near the bottom of the inner tank.

Abstract: A powered cleaning apparatus is provided for routine cleaning of both moderately soiled and severely stained toilet bowls. The device comprises a motor, fluid pump, and cover universally mountable on toilet bowls, and provides a continuous recirculated spray of cleaning solution fluid onto all interior toilet bowl surfaces. The continuous contact of cleaning solution fluid cleans the interior bowl surfaces without manual effort.

Abstract: An apparatus for removing plastic residues from parts of plastics processing machines includes a vessel which is closed in air tight manner by a lid and contains a liquid heat transfer fluid which is heated by heating elements to a temperature above the melting point of the plastic material adhering to the parts. For shortening the working cycle for heating and cooling the heat transfer fluid and also for shortening the cleaning process per se, the interior of the vessel cooperates with a pump which circulates the heat transfer fluid. In order to prevent a decomposition of the heat transfer fluid, inert gas is introduced into the space above the liquid level of the heat transfer fluid for displacing the prevailing air volume.

Abstract: An apparatus for removing plastic residues from parts of plastics processing machines includes a vessel which is closed in air tight manner by an end plate and contains heat transfer fluid. Immersing within the heat transfer fluid is a disk which is operatively connected to a vibrator so as to oscillate for improving the cleaning action. Placed on the end plate is a tubular casing box which is divided into a lower compartment which is essentially sealed off and in which the vibrator is accommodated and into an upper compartment which is open to the atmosphere. At least one pipe traverses the lower compartment for connecting the interior of the vessel with the upper compartment so that vapor and gases may escape through this pipe. A filter is arranged within the upper compartment for absorbing the vapor and gases to prevent the release of obnoxious gases.

Abstract: A device for cooling rubber-coated large containers with liquid nitrogen to crack and remove the rubber coating includes at least one annular duct with sprayers for directing the liquid nitrogen against the inside of the container. At least one axially disposed duct is in the container extending from the bottom to the top with a ventilator causing rotation of the evaporated nitrogen from the bottom through the axial duct and to the upper part of the container.

Abstract: A plunger-type paint roller cleaning device wherein such device is suitably constructed for forcing a solvent longitudinally and peripherally through the nap of a wet, previously-used paint roller. In one embodiment a one-way valve is employed in conjunction with a container suitably designed to receive a paint roller. The plunger of the invention serves to draw external solvent fluid inwardly within the container, whereas a reverse action of the plunger forces the charge of solvent so drawn in to proceed longitudinally and peripherally through the roller nap, such solvent thereby carrying wet paint or other painting medium from the nap for exit from the container. In another embodiment the container receives the roller and then is filled with a charge of solvent, the container later to be closed.
