Abstract: The conventional washing apparatus has a double-cup washing tank that joins and separates to let work be placed therein, with nozzles set on the inner cup to allow a passage between it and the outer cup for spent liquid and/or air. The work is cleaned by washing detergent spirally flowing along the periphery of the inner cup by suction power within the passage, and then dried. Suction is not generated within the inner cup, so the spiral flow is too weak to make the tornado effect. This invention though resolves the above issues by an encased washing apparatus having a capsule-shaped washing chamber that joins and separates, has nozzles thereon, has a work table within that rotates by a drive device, has a drain at the bottom, and is characterized by washing detergent, cleaning water and/or air swirling by negative pressure within the washing chamber and then discharging into a drain.

Abstract: The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles, iron ore piles, and also for piles within and/or being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.
