Patent number: 10668484Abstract: A fluid handling system is provided that includes a controller, a plurality of valves, a pump, and an interface in communication with the controller. The valves can be operatively connected with a conduit to along a flow path. Each of the valves is controlled by the controller for selective movement between a first position and a second position. The first position closes the flow path, while the second position opens the flow path. The pump can be operatively connected with the conduit and the is controlled by the controller for selective pumping of fluid through the flow path. The interface allows selective definition of the flow path through the valves.Type: GrantFiled: July 21, 2017Date of Patent: June 2, 2020Assignee: Alfa Wassermann, Inc.Inventors: Kurt Spiegel, Blaine J Marsh, Christopher A DeBlasis, Fernando J Garcia, Ian Eric Lynes, Raymond A Hathaway

Patent number: 9405836Abstract: A continuous flow centrifuge system is provided. The system includes a rotor, a stator, a stator housing, upper and lower bearing plates, upper and lower bearings, first and second snap rings, and lip seal. The upper bearing rotatably secures a shaft of the rotor in the upper bearing plate. The first snap ring secures the upper bearing to the rotor shaft. The lip seal is over the upper bearing and forms a rotatable seal with the upper bearing plate. The second snap ring secures the lip seal to an inner diameter of the upper bearing plate. The upper and lower bearing plates are secured to the stator housing so that the rotor is operatively aligned with the stator.Type: GrantFiled: May 3, 2012Date of Patent: August 2, 2016Assignee: ALFA WASSERMANN, INC.Inventors: Kurt Spiegel, Sorin Weissman, Bill Lepse, Blaine J.
