Abstract: A continuously variable transmission system having a fixed variable diameter pulley connected by a drive belt to at least one other pulley. A tensioner pulley maintains the tension on the drive belt within predetermined limits as the effective diameter of the variable diameter pulley changes. The effective diameter of the variable diameter pulley is determined by a balance between a resilient force biasing a plurality of belt engaging members in a predetermined direction and a radial force acting on the plurality of belt engaging members in the opposite direction. In a first embodiment, the resilient force biases the plurality of belt engaging members outwardly and the radial forces are generated by displacing the tensioner pulley to increase the tension on the drive belt. In an alternate embodiment, the plurality of belt engaging members are biased inwardly by a resilient force and are displaced outwardly by centrifugal forces.

Abstract: A centrifuge device is provided which may impart selectively controlled centrifugal force to samples under consideration, or a shaking or agitation movement to the samples, as required. A feature of the invention is the use of two roller clutches on the single drive shaft of the device so that a selective movement may be imparted to the samples through the same drive by utilizing a locking mechanism to provide rotation from the shaft in opposite directions. Rotation in one direction causes the imposition of centrifugal force through one clutch, while rotation in the opposite direction causes rotation through the second clutch and the imposition of agitation. In that direction, the sample support mechanism is moved vertically, controlled by a cylinder cam. A further feature of the invention is selective agitation movement and selective degree of agitation through selection of a particular cam profile.

Abstract: A method for plasmapheresis includes withdrawal of a quantity of blood from a blood donor to an annular primary container forming part of a closed flexible processing assembly positioned in a processing space provided in a centrifuge rotor and conformed to the processing assembly. During the withdrawal, the rotor is caused to perform an oscillating movement for agitating the blood whereupon the blood is centrifuged in the primary container to be separated into blood cells and plasma. While the centrifugation is going on, the primary container is compressed to expel the plasma fraction to a secondary container. Liquid diluent is then fed to the primary container to resuspend the blood cell fraction while agitation is again accomplished by oscillating the rotor, whereupon the blood cell fraction is returned to the blood donor.
