Abstract: A dishwasher (1) comprises a washing chamber (2) configured for receiving crockery (3) to be washed, which can be accessed via a first lateral zone (5a) and a distinct second lateral zone (5b). The dishwasher (1) includes a lid (6) configured for being rotated with respect to the washing chamber (2), around a rotation axis (7) passing through the washing chamber (2). In a first position, the lid (6) prevents accessing the washing chamber (2) both via the first lateral zone (5a) and via the second lateral zone (5b). In a second position, the lid (6) allows accessing the washing chamber (2) only via said first lateral zone (5a). In a third position, the lid (6) allows accessing said washing chamber (2) only via the second lateral zone (5b).

Abstract: Systems, methods, and techniques for cleaning sinks and dishes are provided. In some embodiments, a cleaning system comprises at least one fluid supply, at least one opening in a side wall of a sink basin, and at least one nozzle positioned along an exterior of the sink basin. The nozzle is configured to receive fluid from the fluid supply, and dispense fluid through an opening in a side wall of the sink basin to an interior surface of the sink basin. In some embodiments, the nozzle is configured to dispense fluid to the interior of a sink basin, such that substantially all surfaces of the interior of the sink basin are covered with a thin layer of fluid. In some embodiments, nozzle dispensing angle, duration of a cleaning cycle, flow rate or amount of dispensing fluid, or activation of a cleaning cycle may be manually or automatically controlled.

Abstract: A liquid processing apparatus includes a substrate holding member configured to rotate along with a substrate held thereon in a horizontal state; an annular rotary cup configured to surround the substrate held on the substrate holding member and to rotate along with the substrate; a rotation mechanism configured to integrally rotate the rotary cup and the substrate holding member; and a liquid supply mechanism configured to supply a process liquid onto the substrate. The apparatus further includes an annular drain cup configured to receive the process liquid discharged from the rotary cup, and provided with a drain port; and a circular flow generation element configured to generate a circular flow within the drain cup when the rotary cup and the substrate holding member are rotated, such that the circular flow serves to lead the process liquid within the drain cup to the drain port.

Abstract: A combination parts washer for cleaning mechanical parts of oil, grease and contaminants. The washer has a cabinet which has two reservoirs. A parts receptacle in the one of the reservoirs receives the parts which are cleaned by ultrasonic waves. An operable sink for manual cleaning is positioned on the top of the cabinet and opens to access the cabinet and reservoir. Fluid from the sink drains to the first reservoir. In the closed position, the sink covers the top of the cabinet and may be used as a sink washer using the attached brush supplied by fluid from the first reservoir. Initial pre-cleaning may be performed in the sink using the brush. Subsequent precision cleaning may be accomplished by immersion and ultrasonic cleaning in the second reservoir.

Abstract: A method and biological cleaning system are provided for cleaning substrate surfaces of oils and/or greases using a biological cleaning system which utilizes a pre-treatment bath and/or post-treatment bath as part of the cleaning system. The pre-treatment and/or post-treatment baths are compatible with the biological cleaning bath and during operation of the system, the used pre-treatment and/or post-treatment baths are recycled to the biological cleaning solution for biodegradation. A system is provided in which none of the pre-treatment, post-treatment or biological cleaning baths need expensive waste disposal. Replenishment pre-treatment and/or post-treatment baths as well as biological cleaning baths are added as needed to the biological cleaning system. Other treatment baths may be added directly to the biological cleaning bath with or without pre- or post-treatment for specific purposes such as a detergent phosphating bath used in the biological cleaning tank to provide a cleaned phosphated part.

Abstract: A drawer dishwasher includes a drawer which is movable from a closed to an open position. A lid is separate from the drawer and is adapted to seal over the top of the drawer when the drawer is in its closed position and to move upwardly and away from the drawer in response to movement of the drawer from its closed to its open position. Recirculation plumbing and draining plumbing are connected to the drawer dishwasher and lead to a remote pump and reservoir for receiving drained fluid from the drawer and for recirculating drained fluid back into the spray assembly within the drawer.

Abstract: A compact kitchenware washing station providing a variety of functions wherein three sink members are adjacently positioned and aligned adjacent to an automatic dishwashing apparatus. For an automatic operation, two of the sinks can be covered to support dishwashing racks with dishes. When a manual operation is desired, the covers are removed and the sink members utilized to provide a wash, rinse, and sanitizing operation. The kitchenware washing station is compact in design so that it can be utilized in even the smallest type of food service operation.

Abstract: A parts washer for removing cutting oil from machined parts includes two open compartments separated by a common heat-conducting wall. A single heater in one compartment heats washing solution in both compartments. The back of the washer has a stepped configuration to protect components from injury while the washer is on the shop floor.

Abstract: An improved blind washing device comprising a frame supporting a plurality of open-ended tubes, closure mechanism for selectably closing said tubes, mechanism for elevating one end of said tubes, a hose connection for delivering water into said tubes, a spray arm, an extensible hose connected to deliver water to said spray arm, an outlet drain and filter mechanism connected between said tubes and said outlet drain.

Abstract: The invention relates to a soaking system for solids. The system includes stacked tanks each of which has a conical bottom. The tanks are connected through perforated valves through which the solids move from the top and water is fed from the bottom. The solids are soaked in a counterflowing water. In one embodiment, two or more similar units are stacked one upon the other for more efficient operation.

Abstract: A parts cleaning machine (10) is provided which includes a cabinet (50) with a rotating carousel (60) therein for supporting articles to be cleaned and a spray bar network (80) for directing cleaning fluid (F) against articles supported upon the carousel (60). The carousel (60) is enclosed within the cabinet (50). A sink (100) is also provided which receives fluid (F) from a line (126) which taps into the spray bar network (80) to utilize cleaning fluid (F) provided by a fluid delivery system (250). The cabinet (50) includes a reservoir (90) at a bottom thereof which collects cleaning fluid (F) utilized by the spray bar network (80) and utilized within the sink (100). A filter (150) processes water from the reservoir (90) to remove contaminants from the cleaning fluid (F). The parts cleaning machine (10) can simultaneously wash articles within the cabinet (50) and within the sink (100).

Abstract: The invention provides a method for removing the oxide surface from water atomized metal powders containing an oxidizer capable of oxidizing chromium from a trivalent to a soluble hexavalent state, whereby chromium oxides are removed from the metal powder surface. The powder is then treated with a dilute acid solution essentially devoid of hydrofluoric acid to remove other hydrated oxides from the metal powder surface. The powder is then water washed and dried.

Abstract: A rinsing tank constructed to allow low volume water flow from an ingress point at one end of the tank to an outlet. Weirs are provided in the path of water flow to normally dam scum driven by the water flow yet allow passage of water. The rinsing water is, therefore, free of scum over a major part of its surface to permit immersion into and withdrawal from clear water of parts to be rinsed. Immersion of parts raises the water level in the tanks whereby scum dammed by the weirs can rise and pass over the weirs to the tank outlet.
