Patent number: 7807059Abstract: During collection of pollutants having a density lower than that of water and carried by a surface layer of a body of water, water of the surface layer is caused to flow into and through a collection vessel having a separation compartment with a top wall, pollutants entrained by the inflowing surface layer water are allowed to collect gravimetrically as a supernatant layer carried beneath the top wall of the separation compartment on water in the separation compartment, and changes of the weight of the collection vessel in the body of water are monitored. Intake and discharge phases may be initiated and terminated to in response to the said weight reaching predetermined values.Type: GrantFiled: October 3, 2008Date of Patent: October 5, 2010Assignee: Surfcleaner ABInventors: Stig Lundback, Jonas Johnson

Publication number: 20100230335Abstract: Apparatus and methods related to centrifugal liquid chromatography are described. An angular velocity can be simultaneously imparted to a large number of chromatographic enclosures. Via centrifugal forces, a mobile phase fluid including a sample can be driven through a stationary phase within the chromatographic enclosure to perform a chromatographic separation process on components of the sample. The use of centrifugation as a driving force can allow significantly smaller stationary phase particles to be employed as compared to high performance liquid chromatography (HPLC). Further, for an equivalent chromatographic separation process, the use of centrifugation can provide much greater separation efficiencies than HPLC.Type: ApplicationFiled: March 12, 2010Publication date: September 16, 2010Applicant: TERRASEP, LLCInventors: Robert R. Kerr, James D. Whitaker, Thomas M. Kerr

Publication number: 20100228056Abstract: The present invention relates to a magnetic separation apparatus for continuous separating and recovering magnetic solid particles from a solid-liquid mixture. The apparatus includes at least one magnetic separation unit and each unit includes: an outer cylindrical vessel having a material inlet, a first outlet, and a second outlet; an inner cylindrical vessel, at least part of which extends along the axis inside the first cylindrical vessel without contacting with the inner surface of the outer cylindrical vessel; and a magnet, rendering the bottom of the inner cylindrical vessel magnetism during the first period and making the part of the surface lose its magnetism during a second period. When the solid-liquid mixture flows through the magnetic surface of the inner cylindrical vessel in the passage, the magnetic solids are absorbed and separated from the mixture.Type: ApplicationFiled: February 22, 2008Publication date: September 9, 2010Applicant: Jiangsu Sinorgchem Technology Co., Ltd.Inventors: Nongyue Wang, Xiaogen Feng, Xiaohui Mao

Patent number: 7785463Abstract: A system, program product and method continuously optimize an ultrafiltration rate during an extracorporeal renal replacement process by modeling physiological and actual rate data. The system maps the sensed, physiological data to a mathematical model to assess the data in terms of the ultrafiltration rate. The model provides parameters used to predict where the treatment is headed based on current conditions. The system processes the parameters in terms of preset criteria to generate the optimized ultrafiltration rate. Where the system is networked, communication of the data may be accomplished using remote and online communication techniques.Type: GrantFiled: March 17, 2006Date of Patent: August 31, 2010Assignee: Children's Hospital Medical CenterInventors: John J. Bissler, Nat Hemasilpin, Marios M. Polycarpou

Publication number: 20100176058Abstract: The present invention relates to a simulated moving bed process, wherein at least one adsorbent is washed after binding of target compound and wherein the outlet of wash liquid from the adsorbent is subsequently passed onto another adsorbent for binding of target compound removed by the washing. In one embodiment, the method comprises binding of at least one target compound using three or more adsorbents connected in series and elution of target compound from said three adsorbents. After the binding to an adsorbent, wash liquid is passed across the adsorbent to recover desorbed and/or unbound target compound, and the outlet of such wash liquid is directed to the adsorbent after the next in the series, to which no feed has yet been added. The target compound is recovered by eluting target compound from the washed adsorbents.Type: ApplicationFiled: June 12, 2008Publication date: July 15, 2010Applicant: GE HEALTHCARE BIO-SCIENCES ABInventors: Mattias Bryntesson, Martin Hall, Karol Lacki
