摘要： A blood component separating device comprises a centrifuge bowl adapted for rotation about its axis in a centrifuge. The bowl defines an outer arcuate wall plus an inner circumferential wall, spaced from the outer wall, to define a arcuate slot adapted for receiving blood components. Access tubing is adapted for communication with the slot. Preferably, an elongated, flexible, collapsible inner liner is provided in the slot. Individual access tubing also may communicate with an elongated container interior between the ends of the elongated, collapsible container. Furthermore, a portion of the slot may define the shape of an outwardly extending spiral, to provide an increasing gravitational field upon fluids therein as the fluid moves along the slot.

摘要： A centrifugal separator for extracting heavy metals from a slurry comprises a centrifuge bowl having an inwardly facing surface over which the slurry runs. A dam at a discharge end of the surface forms a shallow layer of particles which separate preferentially the heavy metals. The surface includes a portion formed by a plurality of annular membrane portions spaced axially and separated by radial rings extending from the surface to a supporting metal bowl. The membranes are deflated or retracted to gradually form annular cups for receiving the separated metals. The membranes are then inflated to discharge the collected materials while the feed is temporarily halted and the bowl continues to rotate.

摘要： Prior centrifugal concentrators for concentrating precious minerals use annular ribs or baffles to trap the precious minerals. Sand or magnetite tends to pack against such ribs, reducing the effectiveness of these devices. In the present invention, the inner surface of the rotating drum is free of obstacles, but forms three continuous zones, a migration zone, a retention zone and a lip zone. The precious mineral is retained in the retention zone by centrifugal force and friction while the unwanted slurry flows over the retention zone and out of the drum.

摘要： A specimen preparation unit having a plurality of interconnected compartments is automatically loaded onto a centrifuge rotor arm at a first rotor position. Each rotor arm has two indexing means for independently rotating the unit about either or both of two axes orthogonal to each other and to the rotor arm. The orientation of the unit with respect to the centrifugal force vector is changed in a predetermined manner so as to cause fluid flow between desired compartments even under conditions of microgravity. The unit is centrifuged in at least two different orientations with respect to the centrifugal force vector. As the fluids move between compartments, the specimen is prepared. After the multistep preparation process is completed, the unit is rotated to another rotor position at which the prepared specimen and/or the entire unit is removed. The centrifugal processing unit is capable of processing a plurality of specimen preparation unit in the same or a different manner. A plurality of the compartments of the specimen preparation unit are connected by force-sensitive valves which prevent reflux and which respond only to forces substantially exceeding gravity. The specimen preparation unit may provide for parallel processing of specimen aliquots.

摘要： A fuel cell power system for use in a weightless environment, such as in space, includes a device for removing water from a water-hydrogen mixture condensed from the exhaust from the fuel cell power section of the system. Water is removed from the mixture in a centrifugal separator, and is fed into a holding, pressure operated water discharge valve via a Pitot tube. Entrained nondissolved hydrogen is removed from the Pitot tube by a bleed orifice in the Pitot tube before the water reaches the water discharge valve. Water discharged from the valve thus has a substantially reduced hydrogen content.

摘要： A hemapheresis system and method in accordance with the invention comprises a stationary closed housing concentric about a central axis and a feed system that moves blood upwardly from the housing lower end toward an outlet port adjacent a substantially closed upper end. Within the stationary housing is a double walled rotor concentric with the housing and rotatable by magnetic means within the housing on sealed end bearings. The space between the rotor walls defines a centrifugation gap into which whole blood is passed and within which centrifugal separation takes place as the rotor is spun at a relatively low rate. Whole blood also seeks to flow upwardly in the space between the rotor and housing, but this path is arranged to have a substantially higher flow impedance, so that the preferential path is within the centrifugation gap. At the upper end of the rotor, lighter matter such as plasma rich in platelets passes continuously inwardly to a central lengthwise passageway leading to an outlet port coaxial with the central axis, while heavier central matter flows through apertures in the outer rotor wall to the upper outlet port. In one example the differential impedance is established by housing and rotor configurations which diverge outwardly with compound curvatures, and with the space between rotor and housing leading to a closed end. In another example the housing-rotor space is of restricted cross section and an opposing flow of compatible fluid is introduced in an intermediate region of the flow path.

摘要： A centrifugal filter separator system operable to separate from oil under pressure, contaminants and water. The centrifuged water port of the centrifugal filter separator of the system is coupled to a differential pressure responsive, sensor control, which automatically senses the presence of a layer of centrifuged water against the internal surface of the rotating drum of the centrifugal separator. The sensor control is coupled to a flow control circuit which in conjunction with the differential pressure sensor control causes automatic removal of an existing layer of centrifuged water from the rotating drum via the water exit port of the separator. When there is no adequate depth layer of centrifuged water on the inner surface of the rotating drum, the sensor control deactivates the water removal circuit, while the flow control circuit maintains a minimum generally constant flow of liquid from the water port of the separator for priming purposes. The flow control circuit is coupled to a pressurized gravity type separator in the system from which separated oil is returned back to the centrifugal filter separator. The gravity separator includes an inverse relief valve circuit for replenishing water evacuated from the gravity separator, with oil from the pressure port of the system pump.
