Abstract: A liquid composition for use in purifying an oil contains a polar polymer, a surface active hydrotrope/solubilizer, and a co-tenside. The polar polymer may be a polyalkylene glycol, such as polyethylene glycol. The hydrotrope/solubilizer may be an anionic sulfonic acid, a phosphate ester-based substance or a non-ionic surfactant from the poly-glycoside family. The co-tenside may be at least one amphoteric co-surfactant, such as sodium caprylimino dipropionate.

Abstract: A disposable integral filter unit 10—suitable for the primary and/or secondary clarification of pharmaceutical fluids—is disclosed. The disposable integral filter unit has an inlet 40 and an outlet 60, and comprises a plurality of filter plates 20n interposed between a pair of end plates 24, 26. Each said filter plate 20n comprises a polymeric framework 28 with a deep gradient filter packet 35 embedded therein. The filter plates and end plates form in the aggregate a substantially fixed integral stack, wherein fluid entering the disposable integral filter unit 10 through said inlet 40 passes the deep gradient filter packet 35 of each filter plate 20n substantially contemporaneously (i.e., in “parallel”) prior to exiting said unit 10 through said outlet 60.

Abstract: A porous filter medium is formed by a pleated cylinder of a depth filter medium. An absolute rated inner filtration layer is arranged between upstream and downstream drainage layers. The depth filter medium is formed from a continuous sleeve. Additionally or alternatively at least the downstream drainage layer may be formed integrally with at least a part of an inner filtration layer. The material of the medium may be a fibrous mass of non-woven synthetic polymeric micro-fibers which are free of fiber-to-fiber bonding and are secured to each other by mechanical entanglement or intertwining, with the diameter of the fibrous structure varying across the medium.

Abstract: The present invention provides at least one cylindrical, close-ended porous, ceramic molten metal filter element connected to an essentially horizontal porous ceramic sealing plate filter element. The cylindrical element extends vertically above the elevation of that sealing plate. The molten metal flow is introduced to the exterior of the close-ended cylindrical elements and the upper surface of the plate element. The cylindrical filter body elements rest on the sealing plate, thus the sealing plate provides all of the structural support for the assembly. The molten metal flows through the porous ceramic material of the cylindrical elements and the sealing plate element to be further flowed downstream, ultimately to the associated casting molds.

Abstract: A fluid filter is formed by manufacturing an air laid batt containing randomly disposed structural fibers and a thermoplastic binder fiber. The interstices between the fibers are fixed by applying a latex resin to the batt, thereby fixing the pore sizes of the filtering media before the filtering media is molded. The filtering media is then molded into shape by using a plunger to tuck the media into an open cavity mold. The mold may be heated and pressure may be applied to the batt to mold the batt.

Abstract: A combined valve and filter mechanism for use in chemical apparatus comprises a valve body having a valve seat connected thereto. A valve stem has a valve at one end thereof for engaging said valve seat and has a cylindrical filter element for telescoping within the valve seat. The mechanism permits filtration of the chemical in situ without a separate filtering mechanism while providing a valve which when open or closed permits the agitation of the chemical in the apparatus without interference with or from the valve and vice versa. In the fully open position, the entire contents of the apparatus can be withdrawn from the apparatus.
