摘要： An apparatus and process for maintaining the purity of solid/granular product and dispensing high purity granular product from a vessel. A noncontaminating surface is provided by a cup, cylinder, or other structure having a surface of silicon, silicon carbide, silicon nitride, sialon, or similar materials and preferably operates as an angle of repose valve in a pressurized system to prevent contamination by undue contact of the high purity product with conventional gastight valves such as ball valves, butterfly valves, pinch valves, etc.

摘要： A rotary drum filter apparatus comprising a rotary drum, a plurality of axial, parallel slots spaced circumferentially around the drum, a filter cloth positioned peripherally around the drum and portions thereof extending into each of the axial slots, flexible metal means inserted into each of the slots over the portion of the filter cloth extending into the slots and caulking means for holding each of the metal means and each of said portions of said filter cloth in a locked position in their respective axial slots. The metal means may comprise a stranded metal cable wherein caulking means are unnecessary.
