Patent number: 9358482Abstract: A filtration apparatus which has a filtration chamber, and the filtration chamber has a fluid inlet, a filtered fluid outlet, a residue outlet, and a filtering element. The filtering element is situated between the fluid inlet and the filtered fluid outlet. The apparatus also includes a wiping member which is situated within, or about, the filtering element and which is adapted to wipe the surface of the filtering element. The wiping member also wipes any residue toward the residue outlet when the apparatus is in use. The filtration apparatus includes a first pumping configured to create a flow toward the filtering chamber, and a second pumping situated within the filtering chamber and configured to induce a counter-flow back toward the first pumping.Type: GrantFiled: July 1, 2010Date of Patent: June 7, 2016Assignee: LIQUIDSTRIP LIMITEDInventor: Gregory Richard Morgan

Patent number: 9327213Abstract: A chromatography column design and a packing device, as well as a method for obtaining a column with a very compact and uniform bed are provided. The bed remains compact and uniform during operation of the column and during sanitization, storage and transportation of the column. The amount of hardware, particularly the hardware parts in contact with product, is minimized, especially with the implementation of an internal liner. With this internal liner, the packed bed can be separated from the column in intact form, or even prepared separately from, and outside of, the column.Type: GrantFiled: February 20, 2013Date of Patent: May 3, 2016Assignee: Bio-Rad Laboratories, Inc.Inventors: Sébastien Lefebvre, Lilian Portier, Maurice Agée

Patent number: 9314710Abstract: A multifunctional device for chromatographic separation, in particular for affinity chromatographic separation of a substance mixture, provides for a uniform fluid distribution on a separation medium and a uniform flow through a stationary phase. The fluid to be separated is passed through a radial inlet line in an upper partial region of the device, to the center of the upper partial region. The radial inlet line is enlarged in the form of a cupola at the center of the upper partial region.Type: GrantFiled: October 18, 2011Date of Patent: April 19, 2016Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventors: Hans-Peter Leinenbach, Franz-Josef Gerner, Stefan Kuhn, Patrick Priesnitz

Patent number: 9213021Abstract: A connector is used to connect a conduit to a threaded orifice of a fluidic component, such as a component of an apparatus for chromatography. The connector includes a flexible fitting, a deformable fitting, and a compression fitting. The flexible fitting fixes the position of the conduit with respect to the threaded orifice. The deformable fitting provides a fluid-tight seal between the fluidic conduit and the threaded orifice. The compression fitting includes an external-thread portion for attachment to the orifice, to urge the flexible fitting toward an outer surface of the fluidic conduit, and to urge the deformable fitting toward both the outer surface and the orifice, a cam portion in mechanical communication with the flexible fitting via a through-hole in the external thread portion, and a graspable portion in rotatable communication with the cam portion.Type: GrantFiled: July 16, 2010Date of Patent: December 15, 2015Assignee: Waters Technologies CorporationInventors: Kenneth R. Plant, John C. Conidi

Patent number: 9175805Abstract: A filtration device is disclosed. The device includes a filter inlet, a filter outlet, and a filter flow path from the filter inlet to the filter outlet. A filter in the filter flow path filters contaminants from lubricant flowing from a lubricant supply to a lubricant destination. A bypass flow path bypasses the filter in the event the filter becomes clogged. The bypass flow path has a bypass inlet in fluid communication with the filter flow path at a location upstream from the filter and a bypass outlet separate from the filter outlet and not in fluid communication with the filter outlet. The bypass outlet is normally closed to permit flow along the filter flow path and opens if the filter becomes clogged so that lubricant is directed along the bypass flow path and through the bypass outlet for disposal without going to the lubricant destination.Type: GrantFiled: September 29, 2011Date of Patent: November 3, 2015Assignee: Lincoln Industrial CorporationInventors: Paul G. Conley, Canlong He, Craig J. Fraser

Patent number: 9034178Abstract: A fluid filter assembly with sight glass provides an upper housing carrying a transparent sight glass for visualizing the interior of the filter assembly and fluids passing therethrough. A sight glass retainer secures the sight glass within the upper housing. A screen filter is carried between the upper housing and a mating lower housing. A fluid inlet port is defined in the upper housing above the screen filter and a fluid output port is defined in the lower housing below the screen filter. The sight glass retainer carries plural fluid deflectors and plural sight glass supports for fluid dispersion and fluid cooling. A pressurized air input communicating with fluid inlet port allows pressurized air to be injected into the assembly to force fluids through the screen filter and out of the filter assembly. A low pressure drain valve and a bypass valve are carried in the lower housing.Type: GrantFiled: April 30, 2012Date of Patent: May 19, 2015Inventor: Michael E. Cofini
