Abstract: A system for securing a blood separator bowl in an autotransfusion machine includes a split ring or collar adapted to grip an enlarged cap on the base of the bowl and a clamp assembly for moving the collar between retracted and expanded positions. In the retracted position, the clamp assembly includes both an overcenter lock system for securing the collar in the retracted position and a backup auxiliary lock in the event of failure. The system further provides for centering the separator bowl on its axis of rotation to prevent undue vibration.

Abstract: A synchronized drive and cable handling system is disclosed for a rotational element, such as a rotational gantry of a tomographic scanning machine, upon which element are carried load devices to which a medium, such as oil or electricity, is required to be supplied through the cables. A pair of spaced-apart sets of idler pulleys are disposed to either side of the rotational element with a cable being wound about the respective pulley sets to form an elongated loop, one end of each respective cable being attached to a load device which is disposed on the rotational element. One pulley set of each pair of sets is disposed about a translatable axis, the position of which is controlled by a lead screw drive to vary the distance between the pair of pulley sets and to thus vary the amount of cable which is played-out and taken-in therefrom.
