DRIVE SYSTEM FOR A CENTRIFUGAL LIQUID PROCESSING SYSTEM Abstract of the Disclosure A drive system for a centrifugal liquid processing apparatus or the like wherein a rotor assembly having a container for receiving a liquid to be processed by centrifugation is rotatably mounted on a rotor drive assembly, which in turn is rotatably mounted to a stationary base. Liquid communication is maintained with the container during rotation of the rotor by means of a flexible umbilical cable which extends from the container to a location external to the apparatus by way of a passageway provided in the support shaft of the rotor assembly and a guide sleeve carried on and rotatably mounted to the rotor drive assembly. The rotor assembly is rotatably driven in the same direction as the rotor drive assembly with a speed ratio of 2:1 and the guide sleeve is rotatably driven in the opposite direction with a speed equal to that of the rotor drive assembly to prevent the umbilical cable from becoming twisted during operation of the apparatus. This is accomplished by a novel drive arrangement which includes a planetary drive gear on the rotor drive assembly which is rotatably coupled to the rotor and guide sleeve by means of a single drive belt.
