| 20090166287 | Fuel Filter and Process for Producing Fuel Filter - Presented is a fuel filter that includes a filter fabric and a plastic support body. The plastic support body includes a pump connection stub, and a first filter part that includes a first surface and a first peripheral edge that accommodates the filter fabric. The first surface faces away from the filter fabric. The plastic support body further includes a second filter part that includes a second surface and a second peripheral edge that accommodates the filter fabric. The second surface faces away from the filter fabric. The plastic support body further includes connecting elements disposed on the first and second filter parts. When the first filter part and the second filter part are joined, the connecting elements interact with each other and the first surface contacts the second surface. | 07-02-2009 |
| 20140183127 | COMPOSITE SEMIPERMEABLE MEMBRANE, COMPOSITE SEMIPERMEABLE MEMBRANE ELEMENT, AND METHOD FOR MANUFACTURING COMPOSITE SEMIPERMEABLE MEMBRANE - A composite semipermeable membrane in which a polyamide separation functional layer is formed on a porous support membrane includes a substrate and a porous support, wherein a standard deviation of a membrane thickness of the separation functional layer is 2.00 nm or less. | 07-03-2014 |
| 20150136686 | Embedded Type, Inverted-filtering and Anti-Clogged Emitter and Drip Irrigation Pipeline - The present invention discloses an embedded type, inverted-filtering and anti-clogged emitter and drip irrigation pipe (tape). The emitter comprises a first component and a second component which are mutually fixed, and a filter cloth sandwiched between the first component and the second component; the first component and/or the second component are provided with a diversion channel, the first part is also provided with a water outlet channel which is capable of exposing the filter cloth and enabling the filter cloth to communicate with a water outlet of a water pipe, the part around the water outlet channel is fixed with the inner wall of the water pipe, and the filter cloth sandwiched between the first component and the second component is a medium leading the diversion channel to the water outlet channel. The present invention has a simple structure, is convenient to manufacture, lay and install, is strong in controllability of flow rate of seepage water, is small, uniform and stable in discharging flow, is little in sensitivity to water pressure change, can prevent physical clogging and chemical and biological clogging, and is wide in application range. | 05-21-2015 |

| 20130098831 | MATERIAL EFFICIENCY AND FABRICATION OF MEMBRANE ELEMENTS - Membrane elements that use multiple membrane leaves may have a limited total active membrane area due to an increased diameter at the ends of the element. Membrane leaves may comprise a permeate carrier positioned between one or more membrane sheets. Adhesive may be used to seal one or more edges of the membrane leaf. The membrane sheets, permeate carrier and the adhesive contribute to the thickness of the edges of the membrane leaf and the diameter at the ends of the element. A reduced thickness of the edges of the permeate carrier may reduce the diameter at the ends of an element. Another permeate carrier sheet may also be used that is distanced from at least one edge of the membrane sheet so the permeate carrier sheet does not contribute towards the increased diameter at the ends of the element. | 04-25-2013 |
| 20140326656 | DIATOMACEOUS EARTH FILTER CLEANING TOOL WITH FLUID OSCILLATION NOZZLE AND DIATOMACEOUS EARTH CAPTURING SYSTEM - Embodiments provide a pool filter cleaning system that comprises an elongate tube having a first end, a second end and length in a longitudinal direction; a hose connector configured to connect to a supply of water under pressure, the hose connector is attached to the first end of the elongate tube. A spray nozzle is located at the second end of the elongate tube such that an outer surface of the spray nozzle and the elongate tube establish a substantially smooth continuous outer surface. The spray nozzle of an exemplary pool filter cleaning system comprises at least one water oscillation chamber configured to oscillate or pulsate fluid flow through the spray nozzle such that fluid output from a plurality of spray nozzle fluid outputs is oscillated or pulsated at a sonic frequency and in directions that have both a radial component and a longitudinal component away the second end. | 11-06-2014 |

| 20080217238 | Spiral filter that receives water from its top, bottom and side - A spiral filter has four layers wound around a central perforated outlet pipe. An input layer which extends not only around the outer sidewall but also to the top side and the bottom side of the filter receives the water to be filtered from all of said sides and feeds the incoming water through two layers containing a filtering media. The water then passes to an output layer which feeds the perforated outlet pipe. | 09-11-2008 |

| 20090314706 | Cartridge Module of Hollow Fiber Membranes - Disclosed is a cartridge module of hollow fiber membranes, which can be easily mounted on and dismounted from a module mounting frame, and allow a process for removal of the inter-membrane clogging to be performed in an effective and simple manner. The cartridge module is mainly characterized in that a water collecting header has an opened first collected water outlet, which is located at the upper portion of the front surface of the water collecting header and can be opened and closed; and a closed second collected water outlet, which is located at the lower portion of the front surface of the water collecting header and can be opened and closed. The inter-membrane clogging can be very simply removed by dismounting, turning upside down, and remounting the cartridge module. | 12-24-2009 |
| 20140284266 | FILTER ASSEMBLY - A filter element includes a substantially cylindrical center tube having a first end, a second end opposite the first end, and a central longitudinal axis. The filter element also includes filter media extending circumferentially around and longitudinally along the center tube, and a plate connected to the center tube proximate the first end. The plate includes an orifice and a cap. The orifice includes a pilot feature configured to locate the filter element at a single circumferential position relative to the longitudinal axis, the cap extending from a top surface of the plate toward the second end and having an inner wall configured to mate with a drain plug. In such embodiments, the orifice and the cap are disposed radially inward of an inner circumference of the center tube, and at least one of the orifice and the cap extends circumferentially around an additional longitudinal axis spaced radially from the central longitudinal axis of the center tube. | 09-25-2014 |
