Abstract: A commercial warewasher consecutively washes racks of soiled ware, such as dishes, through a machine cycle which includes recirculating wash water over the ware followed by a fresh water spray rinse. Part of the wash water is drained and a second portion is retained in the machine after each rack of dishes is washed, then combined with subsequent fresh rinse water spray to provide a volume of water sufficient for pumped wash recirculation for the next rack without cavitation. When a drain valve is opened, water pressure to the wash arm system is reduced, flow through it decreases, and when the pump stops the wash system will drain by gravity to the lowest point in the wash system plumbing. In the meantime the pump discharges wash water until the level of water in the sump and/or its associated outlet pipe reaches the level of the pump impeller eye. The pump begins to cavitate and effectively ceases to pump water.

Abstract: A washing machine assembly includes first and second liquid ducts having respective inlets and outlets. The first duct has an interior volume greater than the second duct, and the outlet of the first duct is at a level higher than the outlet of the second duct. A pump pumps liquid to the ducts, and a valve controls the flow of liquid from the pump to the inlets of the first or second ducts. The valve includes a housing having an inlet connected to the delivery side of the pump and first and second outlets connected respectively to the inlets of the first and second ducts. A valve closing element within the housing is movable from a stable first unblocking position spaced from and aligned with the first outlet to a first blocking position closing the first outlet, such that the pumped liquid flows to the second duct. At the same time, a bypass allows some pumped liquid to bypass the closing element into the first duct.

Abstract: A centrifugal soil separator for use in dishwashers and the like. A portion of the dishwashing liquid being circulated during the dishwashing operation is directed against a housing wall portion of the soil separator to spin the separator at high speed. The separator defines a soil collecting portion to which soil pumped through the separator is directed so as to be separated from the dishwashing liquid. Pumping of the liquid through the separator is a function of the rotation of the separator. Washing liquid may be directed reversely through the separator upon completion of the washing cycle for washing out the collected soil from the separator and permitting it to be disposed of through the normal drain structure of the dishwasher. The separator may be rotated during the washing-out operation for improved automatic cleaning thereof.

The washing apparatus is comprised of a container for housing the food articles, an agitation system and washing system for removing undesired foreign materials from the surface of the food articles without causing bruising or damage, and a discharge system.

Abstract: A fingernail cleaner comprising an enclosed fingernail receiving receptacle having an opening in the upper end for receiving one or more of a person's fingers to be cleaned, which opening fits closely around the fingers to prevent liquid from splashing out through the opening, and a liquid nozzle for spraying liquid at one or more angles behind the end of the fingernail for cleaning the fingernail, with a drain at the bottom of the receptacle for draining the liquid from the recptacle, and a selective source of liquid for providing a pulsating liquid stream to the nozzle.

Abstract: A waste receptacle is provided at the bottom of a mobile, wheeled, open topped vessel. A suction pipe in the vessel is coupled to, and extends from, a water supply pipe into the vessel. A drain pipe extends from the vessel at the bottom thereof for draining water from the vessel. A motor driven pump and a plurality of valves mounted on the outside of the vessel selectively apply the pump to the pipes whereby in one valve operation the pump supplies water via the water supply pipe under pressure and the output of the nozzle cleans the surface of an item onto which it is directed in the vessel so that material removed from the item is collected in the waste receptacle, and in another valve operation, the pump draws water or water mixtures from the vessel through the suction pipe and discharges under pressure via a high pressure hose and nozzle. In another valve operation, the pump draws water from the water supply and discharges it under high pressure via a high pressure hose for external cleaning.

Abstract: A truncated cone shaped pump support and fluid deflector is provided with a plurality of intake apertures in the wall thereof and the pump is supported in the wall below the upper side of the sloping wall so that the intake is uppermost and situated above the intake apertures. This maintains the pump and motor submersed in solvent at all times for cooling purposes and also provides self-priming characteristics to the pump. If the pump is switched on for too long a period, most of the fluid will be pumped to the sink of the parts washing machine thus starving the pump which, if fully exposed, can overheat and become damaged. Furthermore, with conventional pumps, if starved of fluid, air locks often occur which prevents the pump from operating correctly once liquid or fluid is restored thereto.

Abstract: This liquid recirculation system is particularly suitable for flammable solvents since the liquid is pumped by an air powered pump. The system has a solvent tank with a sink mounted on top of it for drainage into the tank. A centrifugal liquid pump is immersed below the liquid level in the tank for pumping liquid to a spout over the sink. A centrifugal air turbine is mounted above the liquid level for driving the pump. The liquid pump and air turbine have identical housings at opposite ends of a tubular housing. A drive shaft mounted in bushings or bearings at the ends of the tubular housing connects impellers in the turbine and pump. Each impeller is a flat disk with a plurality of flat upstanding blades with a substantially larger number of blades on the turbine impeller than on the pump impeller. Air enters the turbine tangentially and is discharged through an outlet on the top of the turbine.

Abstract: The invention relates to a dish washing machine, comprising a receptacle which can be opened to one side - preferably upwards - which encloses the wash zone and forms a water reservoir at the bottom, comprising also at least one dish basket or similar device which can be inserted into the wash zone and secured, and an offset spray pipe which passes through the spray zone from bottom to top in a preferably vertical direction, the spray pipe having a number of superposed jets in its side and the bottom of which extends into the water reservoir and contains a water pumping device, in particular a screw-type impeller which is coupled to an electric motor.
