Abstract
Centrifugal processing apparatus in which a processing chamber is rotatably mounted with respect to a stationary base. An umbilical cable segment is fixed at one end substantially along the axis of the processing chamber at one side thereof, with the other end of the cable segment being attached substantially on the axis in rotationally locked engagement to the processing chamber. Frictional heating and drag of the umbilical cable segment during rotation thereof is alleviated by providing a flexible sheath having a variable radius which defines an outer surface contour conforming to the inner wall surface of a curved support to thereby provide non-slipping rotary motion of the umbilical cable segment.
