Abstract: In a pressure diffuser, clogging of the tapered inlet passageway at the bottom of the vessel is minimized by providing a number of lubricating fluid introducing nipples disposed circumferentially around the annular passageway. The nipples introduce lubricating fluid so that it flows upwardly along the inner wall of the vessel. The vessel inner wall and the bottom support for the screen at the passageway are polished and free of projections, so that friction is minimized. The nipples are provided in sets that are staggered so that a nozzle is placed about every 15.degree. around the circumference of the vessel, and a common annular header--mounted on the support legs of the vessel--provides the lubricating fluid. Should screen movement slow as a result of paper pulp properties near the screen bottom support, the flow rate of lubricating liquid can be increased so as to significantly dilute the pulp at the passageway until slow movement of the screen is overcome.

Abstract: A laundry machine is constructed to discharge liquid from fixed nozzles located within a fixed tub, through holes in the bottom of a basket within the tub.

Abstract: A valve is provided for use in an automatic washer which is positioned in a liquid conduit for directing a flow of wash liquid to a first spray jet during a first predetermined condition of the washer and for directing a flow of wash liquid to a second spray jet during a second predetermined condition of the washer. In a particular embodiment of the invention, the valve is a centrifugal valve and the predetermined conditions of the washer are the rotational speeds of the basket. When the basket rotates at a relatively slow speed, such as during agitation, liquid is directed to a spray jet which enhances agitation. When the wash basket is rotated at a high speed, such as during spin, the wash liquid is directed to a spray jet which enhances the rinsing of the wash load.

Abstract: Now discovered that a resonance rotating wave sustained by a rotating fluid jet can achieve a high level of agitation as required in washing devices. The rotating fluid wave is created by one or more constant flow rotating fluid jets that are rotating at a speed near the natural frequency of a wave in the washing chamber. The rotating fluid jets are produced by a pump mounted within a rotating nozzle housing within the main washing container. The nozzle housing with pump, flow passages and nozzles is rotated to produce the rotating fluid jets. Since only rotational motion is used to produce agitation with the resonant wave-jet agitator washing machine the mechanical components are greatly simplified as compared to a conventional oscillating motion washing machine.

Abstract: The screens of a pulp treating vessel, such as a paper pulp thickener, or diffuser, are back flushed in a simple yet effective manner. The screens are mounted to a supporting conduit within a vertical vessel, and a cylinder is connected at one open end to the conduit, and the other open end is disposed within the pulp inside the vessel. A piston is mounted within the cylinder and relative movement between the piston and cylinder is effected periodically in order to force liquid from within the cylinder into the conduit and out the screens, backflushing the screens and preventing clogging. Since no additional volume of liquid is added to the vessel during backflushing, no surge occurs in the vessel. Conventional accumulators, on/off valves, and the like can be eliminated while--in the case of diffusion washing--efficiency can be increased as much as 20-30%, and capacity increased as much as about 15%.
