20090127185 | FILTER ELEMENT - The invention relates to a filter element for filtering fluid for a motor or gearing, comprising a first filter medium which is arranged in a cylindrical way, with the fluid impinging in a perpendicular way on the circumferential surface of the first medium for filtering in an associated filter apparatus, then penetrating and passing through the same. The filter element comprises a second filter medium with a filter density differing from the first filter medium, the first filter medium and the second filter medium being stacked upon each other as filter layers and being jointly wound in a spiral manner. A desired purity of the fluid can thus be achieved more quickly than in filter elements which exclusively allow a radial passage of the fluid through the filter elements. The spiral configuration also achieves a higher dirt absorption capacity. | 05-21-2009 |
20100038304 | FILTER MEDIUM - The instant invention generally provides a porous filter medium, a porous composite filter medium, a filter assembly, processes of making the same, and processes suitable for filtering contaminants from liquids. | 02-18-2010 |
20100224551 | MICRO FLUIDIC DEVICE, SEPARATION METHOD AND SEPARATION APPARATUS - A micro fluidic device includes a separation membrane that has an upper surface and a lower surface opposing to each other and a side surface; a plurality of base materials that sandwiches the separation membrane; a first channel and a second channel that are partitioned from each other by the separation membrane; a first feed port that is connected to the first channel; and a first discharge port that is connected to the second channel, wherein the first channel comes into contact with at least a part of the upper surface and the lower surface of the separation membrane, the second channel comes into contact with at least a part of the side surface of the separation membrane, and a fluid is movable in a surface direction within the separation membrane. | 09-09-2010 |
20130043182 | WATER FILTER - A filter for filtering water includes a compound material installed between the upper supporting seat and the lower supporting seat; the compound material being formed with an high density fiber layer, an active carbon layer surrounding the high density fiber layer and a fiber layer surrounding the active carbon layer; the upper supporting seat having a cover plate, an inner ring, an middle ring and an outer ring; the lower supporting seat having a cover plate; an inner ring; a middle ring and an outer ring; the high density fiber layer being installed between the platforms of the upper and lower supporting seat; the active carbon layer being installed between the fiber filtering material of the upper supporting seat and the fiber filtering material of the lower supporting seat; and the fiber layer being installed between the upper and lower supporting seat. | 02-21-2013 |
20140183126 | END MEMBER FOR SPIRAL SEPARATION MEMBRANE ELEMENT, SPIRAL SEPARATION MEMBRANE ELEMENT AND SEPARATION MEMBRANE MODULE - An end member ( | 07-03-2014 |
20150122724 | FILTRATION SYSTEM - The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system. | 05-07-2015 |
20160023136 | End Plug for Precoat Filter Element - A precoat filtration element for a condensate polisher system that yields high weld strength in the form of a septa having a core with a plurality of perforations and wound filter elements, the wound filter elements wound around said core, and the septa including an extension flange at one end; and an end fitting having a solid base and a threaded post, the end fitting being slideably engaged within the extension flange such that an outside wall of the solid base is in mechanical contact with an inside wall of said extension flange, and upon insertion, the threaded post is coaxial with the septa center axis, and extends longitudinally outwards away from said septa. Spot welding the end fitting solid base to the extension flange provides high tensile strength over prior art designs. | 01-28-2016 |
