Method and Tooling for removing material from holes or orifices (round or other shapes) or the like in a workpiece, the method and tooling providing means for directing at least a first portion of an abrasive flow composition under pressure from a main body of composition from one side of a workpiece to another side of the workpiece (i. e. about the workpiece) so as to permit at least a second portion of the abrasive flow composition also under pressure from the same main body of composition to easily flow through the holes therein. In the preferred embodiment a first portion of the composition which is directed about the workpiece is returned to a point adjacent another side of the workpiece and is directed at an angle to the flow of the second portion of the composition through the holes in order to produce an interaction between the flow of said first and second portions of said composition.

A scraper nozzle which provides a high pressure, uniform sheet of water. The nozzle is preferably used in the upstream portion of the prewash zone of a warewasher. Wares, such as dishes, are contacted by the sheet of water and the materials on the dishes are scraped off. The nozzle comprises a planar surface and an arcuate surface. The arcuate surface terminates in a discharge edge which is characterized by a plurality of protuberances. The water flows across the discharge edge and forms the uniform sheet of water.

A horizontally sliding seal tight door is provided for a warewasher. The leading and trailing edges of the door are formed to mate with guide members secured to the sides of the door opening. When in the closed position the edges of the door in combination with the guide members direct the water contacting the door into the warewasher.

A method of making a solid cake-like detergent for ware and hard surface washing, which cake-like detergent is the product of hydration and sequestration reactions, which includes: blending an alkali metal hydroxide and a hardness sequestering agent to form a dry powdered detergent mixture; flowing the mixture to form a particulate stream; moistening the particulate stream to form moistened particulates; depositing the moistened particulates in a receptacle; and forming the solid cake-like detergent in said receptacle.

An apparatus for forming a solid cake-like detergent. A dry powdered detergent mixture is discharged downwardly as a flowing particulate stream. The particulate stream is moistened by a spray of water. The moistened particulates are collected in a container in which the detergent is solidified and formed.

A device for holding flatware which flatware is cleaned in a commercial warewashing machine is disclosed. The device is secured to a conventional dolly. A drive wheel on the device engages the conveyor pan. As the dolly moves, the drive wheel oscillates a frame about a fixed axis. The frame carries the baskets which loosely hold the flatware. As the dolly moves the flatware is tossed to and fro eliminating nesting to ensure all surfaces are contacted by the wash water.

A flowable abrasive composition comprising a polyboronorgano silicon compound and dispersed abrasive granules, said composition being modified with a gel formed from a metallic soap (8-22 carbon atoms) and a hydrocarbon oil. The composition is especially useful for honing, abrading, deburring or polishing surfaces, especially metallic surfaces.

A pulper to convert bulky, solid wastes from food service establishments into a uniform, moist pulp. The material is pulverized in a first section and transferred as a slurry to a second section where the slurry is dewatered by an auger. To prevent clogging of the auger, a portion of the liquor extracted from the pulp is introduced as a jet stream into the upstream end of the auger to create turbulence. Additionally, a reverse flow of water through a drain chamber in excess of the amount of water required for make-up in the system is employed to prevent clogging of the screen covering the drain.
