Patent number: 8596292Abstract: A controlled flow drain having an upper flange coupled to a lower flange. The upper flange defines an inlet cavity and the lower flange defines a swirl chamber. The inlet cavity and swirl chamber are in fluid communication via a swirl nozzle defined within a swirl nozzle plate that separates the inlet cavity from the swirl chamber. After separating debris within the drain fluid, the drain fluid is accelerated through the swirl nozzle and discharged into the swirl chamber, and more debris is thereby separated and eventually settles into an annular groove. The drain fluid may then exit the lower flange via an exit control passage. The swirl chamber may be flushed with a series of flushing liquid injection ports symmetrically-arrayed about the annular groove. Flushing the swirl chamber removes fluidized debris and also remove any built up fouling present on the swirl nozzle and exit control passage.Type: GrantFiled: August 22, 2011Date of Patent: December 3, 2013Assignee: Dresser-Rand CompanyInventor: William C.

Patent number: 8590713Abstract: A centrifugal separator having a separation chamber and a collection chamber utilizes an axially-oriented structure which extends from the spin structure, or spin plate, up and into the vortex finder. The axially-oriented structure decreases turbulence within portion of the separator in axial adjacency with the spin structure, including the separation chamber in which the solids are collected. The reduction of turbulence substantially reduces the entrainment of solids in the rising stream of liquid flowing to the vortex finder, and thus increases the efficiency of the separator. The spin structure may comprise a truncated cone mounted with a portion of the truncated cone in the separation chamber and the remainder in the collection chamber.Type: GrantFiled: May 26, 2010Date of Patent: November 26, 2013Assignee: Claude Laval CorporationInventor: Steven D.

Patent number: 8501015Abstract: A centrifuge for separating blood having a camera observing fluid flow, and a controller controlling the flow. The location of an interface is detected by image processing steps, which may comprise the steps of “spoiling” the image, “diffusing” the image, “edge detection”, “edge linking”, “region-based confirmation”, and “interface calculation”. “Spoiling” reduces the number of pixels to be examined preferentially on orthogonal axis oriented with respect to the expected location of the interface or phase boundary. “Diffusing” smoothes out small oscillations in the interface boundary, making the location of the interface more distinct. “Edge detection” computes the rate of change in pixel intensity. “Edge linking” connects adjacent maxima. “Region-based confirmation” creates a pseudo image of the regions that qualify as distinct. “Final edge calculation” uses the points where the shade changes in the pseudo image, averages the radial displacement of these points for the interface position.Type: GrantFiled: November 16, 2012Date of Patent: August 6, 2013Assignee: Terumo BCT, Inc.Inventors: Christopher Fletcher, William Sweat, Jeremy Kolenbrander, Aditya Dalvi, John R.

Patent number: 8398734Abstract: The invention relates to a cyclonic separator comprising a throat portion (4) arranged between a converging fluid inlet section and a diverging fluid outlet section, to generate a swirling fluid flow in a downstream direction. The diverging fluid outlet section comprises an inner primary outlet (7) for condensables depleted fluid components and an outer secondary outlet for condensables enriched fluid components (6). The cyclonic separator comprises a volute diffuser (9, 9?) connected to one of the outlets (6, 7), which comprises a volute outlet duct (90, 90?) defined by a volute axis (I1), forming a spiral shape around the central axis (I). The outlet duct (90, 90?) comprises a vortex chamber 95. The vortex chamber is provided to transform axial momentum of the swirling fluid flow with respect to the central axis (I) into tangential momentum with respect to the volute axis (I1).Type: GrantFiled: August 1, 2008Date of Patent: March 19, 2013Assignee: Twister B.V.Inventors: Cornelis Antonie Tjeenk Willink, Marco Betting, Frederik Albert Lammers

Publication number: 20130043185Abstract: A whirlpool skimming device removes surface debris from a pool by creating a whirlpool having an upper bound at the surface of the pool. The uppermost portion of the whirlpool is free standing and is not bounded by the device. The device includes an outer cup-shaped portion and an inner cup-shaped portion coaxially disposed therein. An opening is disposed in the bottom of the inner cup-shaped portion which communicates with a source of suction which is preferably a Venturi tube feeding the outlet water to a filter bag. There is a first nozzle supplying water at an upper, inner edge of the inner cup-shaped portion at a slightly downward angle in a first direction, and there is a second nozzle supplying water at a lower, outer edge of the inner cup-shaped portion and mounted on an opposite side of the inner cup-shaped portion.Type: ApplicationFiled: August 16, 2011Publication date: February 21, 2013Inventor: Joseph Iacovacci
