Abstract: A two-tube centrifuge separates light material and heavy material from an input mixture. A hollow drive shaft rotates a central body member about an axis of rotation. Two hollow arm assemblies, each having circular cross-section, are mounted on diametrically opposite sides of the central body. Each arm assembly includes an outer housing tube, an intermediate tube, and an inner tube that is longer than the intermediate tube. An end cap having a removable plug is mounted on the outer end of the housing-tube of each arm assembly. The inner ends of all three tubes are mechanically interlocked in a manner to cantilever mount the inner and intermediate tubes to the central-body with their outer ends spaced from the internal surface of the end cap. An input-mixture path extends through the hollow drive shaft, through the central-body, and into a cylindrical space between the inner and intermediate tubes of each arm assembly.

Abstract: The present invention provides an apparatus for separating components of a fluid having an outer housing containing a core wherein three separate fluid pathways are provided to allow continuous separation of biological fluids.

Abstract: The teachings of the present disclosure provide methods and apparatus for removing substances from a process fluid. The system may include a centrifuge body rotatable around a longitudinal axis, the centrifuge body having a first end and a second end. The first end may be configured for receiving a process fluid. The second end may be configured for dispensing a clarified fluid. The centrifuge body may include a first working space and a second working space. The working diameter of the second working space may be greater than the working diameter of the first working space.

Abstract: A self-cleaning centrifuge for clarifying contaminated liquids has a rotor assembly comprising nested first and second sets of concentric cylinders supported for rotation about an axis. The sets of concentric cylinders are rotatably connected. A motor is connected to rotate one of the sets. Contaminated liquid is supplied to the nested cylinders, and the liquid provides coupling between both of the sets so that both sets rotate about the axis. Centrifugal force causes foreign matter to collect on the circumferential surfaces of the cylinders. The resultant clarified liquid is collected for reuse. A selectively utilized brake provides sudden braking of one of the rotating sets to purge collected foreign matter from the cylinders. The purged foreign matter is collected for disposal.

Abstract: A fractionator includes a shaft attached to a drum which is positioned in a housing and which is rotatable about a substantially horizontal axis and has an inlet means for suspension and at least two outlets for fractions. The drum has a first end and a second end and includes at least two fluid tight walls surrounding the axis. The drum also extends in its longitudinal direction between the first end and the second end to define a fluid channel. The fluid channel extrends substantially parallel to the axis from the first end to the second end and continuously in a circumferential direction of at least 360.degree..

Abstract: In a multi-chamber centrifuge for gassing or degassing of liquids which has a floor 7, a corresponding lid 3 placed at a certain distance, with gaps to permit the passage of gas in the floor 7 and lid 3, with a liquid pipe connection in the lid 3 and two sets of coaxially mutually fitting cylinders, the set (=rotor) with the rotating cylinders rises from the floor 7, while the other set (=stator) descends from the lid 3 and is static. The cylinders of one set each penetrate the gaps between the cylinders of the other set, and each set of cylinders leaves a radial gap by reaching just short of the opposite base (either the floor 7 or the lid 3). At least some of the cylinders of the rotating set can be made at least partially of a woven material which can be fashioned like a sieve. On the static cylinders 4, vibration generators 19 and/or heating devices 13 may be installed (FIG. 1).

Abstract: A system for continuously esparating lighter and intermediate density matter, such as plasma rich in platelets from whole blood moves blood through a diverging centrifugation gap between inner and outer walls of a rotor rotating about a central axis within an outer housing. The centrifugation action creates layered flow along an intermediate section. However by crating trailing wakes in the gap between the rotor and housing, localized remixing patterns tending to move in the opposite direction are induced in the layered matter. Platelet rich plasma may then be extracted through adjacent platelet concentrate ports on the inner wall of the rotor. An interior passageway system passes the platelet rich plasma to a platelet concentrate reservoir. Recirculation of blood in the rotor-housing gap between the output and input, and pumping action provided by the diverging centrifugation gap, aid in enhancing throughput and concentration levels.
