Abstract
A locking ring having castellations is provided for a swinging bucket-type centrifuge. The locking ring is constructed such that the castellations can be angularly positioned relative to the rotor to either block or permit the buckets to swing outwardly during operation. The angular positioning of the castellations relative to the buckets is accomplished by relative angular acceleration and deceleration between the rotor and the locking ring.
