Publication number: 20130087496Abstract: A disposable filtering unit includes a tube having a connection portion and an outlet respectively located on two ends thereof, and the connection portion is connected to a faucet body. The tube has a first path unit and a second path unit which has a filtering unit. A valve unit is located on a side of the tube so as to change direction of water flow to guide water to enter the first path unit and flow out from the outlet, or to enter the second path unit and flow out from the outlet via the filtering unit. The tube can be disengaged from the faucet body and disposable, and the filtering unit filters water to ensure that the water is clean.Type: ApplicationFiled: October 11, 2011Publication date: April 11, 2013Inventor: Yao-Tung Chen

Patent number: 8414515Abstract: A conduit tube (90) that communicates with an intracardiac blood inflow port (50) and a liquid medicine injection port (72) and allows blood from the intracardiac blood inflow port and a liquid medicine from the liquid medicine injection port to flow into a cardiotomy section (2) is inserted from above downward in the cardiotomy section 2. A blood flow channel (93) for the flow of blood and a liquid medicine flow channel (95) for the flow of a liquid medicine are formed independently of each other in the conduit tube. With respect to the vertical direction, the lower end of a blood conduit tube portion (94) that forms the blood flow channel is located at a lower position than the lower end of a liquid medicine conduit tube portion (96) that forms the liquid medicine flow channel. This prevents the generation of negative pressure in the liquid medicine flow channel due to the flow of blood. It also reduces the resistance to the inflow of a liquid medicine into the cardiotomy section.Type: GrantFiled: August 21, 2008Date of Patent: April 9, 2013Assignee: JMS Co., Ltd.Inventors: Yutaka Katsuno, Minoru Tanaka

Patent number: 8404118Abstract: The invention relates to a filter unit for purification of impure water, which could be seawater intended for ballast water, pool water, waste water or the like. The purification is performed by means of filter modules comprising filter means with dead end filter elements of a sintered material, and the filter unit facilitates alternating backwashing of the filter means at the same time as the filter unit may perform filtration of the impure water. The invention likewise relates to use of a dead end filter element in a de-gassing version, the filter element comprising a top end, a bottom end and a plurality of substantially parallel arranged channels with blockings in different ends.Type: GrantFiled: April 2, 2009Date of Patent: March 26, 2013Assignee: S R Light APSInventor: Povl Kaas

Patent number: 8404110Abstract: An apparatus for diverting rainwater includes a body having a top portion, a bottom portion, and a central portion. A diverter is disposed within the central portion, and has a lower portion and an upper portion. The lower portion of the diverter, together with one or more walls of the body, defines a containment configured to capture rainwater that enters through the top portion. An opening in at least one of the walls of the body is configured to divert rainwater from the containment. The body also includes a bypass flow area extending through the central portion adjacent to, and separate from, the containment, where the bypass flow area has a cross-sectional area that is substantially equal to or greater than a cross sectional area of the top and bottom portions.Type: GrantFiled: August 26, 2011Date of Patent: March 26, 2013Assignee: Fiskars Brands, Inc.Inventor: Andrew P. Block

Publication number: 20130048552Abstract: The invention relates to a filter device, in particular for fluids polluted with admixtures of water, such as diesel oil, comprising a filter housing (1) which has a fluid inlet (43) and a fluid outlet (44) and in which at least one filter element (9) can be received. During the filtering process, the respective fluid can flow through the filter medium (11) of the filter element from the unfiltered side (14) to the filtered side (13) of the filter medium, which surrounds an inner filter cavity (17). On at least one side of the filter medium (11), a water-separating system (23) having a separating region (25) for separated water is present. The water separating system is connected via at least one water opening (35) that is open toward the separating region (25) to a water collecting chamber (45), and the filter element (9) has a passage (29) that forms a fluid connection to the inner filter cavity (17) and can be connected to an element receptacle (47) of the filter housing (1).Type: ApplicationFiled: March 2, 2011Publication date: February 28, 2013Inventors: Richard Eberle, Micha Kreibig, Markus Dewes

Publication number: 20130020240Abstract: An appliance for washing objects is disclosed that effectively and energy-efficiently filters oil-based residue from a fluid such as washing fluid that drains from a basin in the appliance. In one illustrative embodiment, an appliance includes a novel filter assembly for filtering oil-based residue out of the washing fluid. The filter assembly includes a filter layer composed of a material that is both oleophilic and hydrophobic. The filter assembly forms part of a fluid distribution system that has different configurations. A first configuration allows for recirculating filtered wash fluid from an outlet of the filter assembly back into the basin of the appliance. A second configuration allows for draining both the washing fluid from the outlet of the filter assembly and the oil-based residue from a bypass zone of the filter assembly to an appliance outlet.Type: ApplicationFiled: July 20, 2011Publication date: January 24, 2013Inventors: Paul Matthew, Ramasamy Thiyagarajan, Nikhil Subhashchandra Tambe, Duraiswamy Srinivasan

Patent number: 8356714Abstract: An apparatus for separating particles includes a first planar wall and a spaced apart second planar wall parallel to the first planar wall. The first planar wall and the second planar wall define a passage therebetween, which is disposed along a fluid flow axis. A first plurality of spaced apart elongated ridges extends into the passage from the first planar wall. The first plurality of spaced apart elongated ridges is disposed along a diagonal direction relative to the fluid flow axis. When a fluid is moved through the passage in a direction corresponding to the fluid flow axis, particles of a first type will tend to move in a first direction that is diagonally away from the fluid flow axis and particles of a second type, different from the first type, will tend to move in a second direction that is different from the first direction.Type: GrantFiled: June 2, 2010Date of Patent: January 22, 2013Assignee: Georgia Tech Research CorporationInventors: Todd A. Sulchek, Alexander Alexeev, Gonghao Wang

Patent number: 8313656Abstract: A variable wash flow filter assembly includes guide that is operable to guide a wash velocity control cone between a minimal position and a maximum position. The guide defines at least one activation deltaP window downstream of a conical gap between the wash velocity control cone and a frusto-conical wash filter. The fuel flow through the conical gap and the activation deltaP window is operable to position the wash velocity control cone between the minimal position and maximum position to selectively split a fuel flow through an inlet into a burn flow through a thru flow port and a filtered flow thru the frusto-conical wash filter and filtered flow port.Type: GrantFiled: September 9, 2011Date of Patent: November 20, 2012Assignee: Hamilton Sundstrand CorporationInventors: Kevin Gibbons, Francis P.
