Abstract
A shuttle exchanger exchanges a shuttle circulating in a reentrant lumen by actuating a channel selector to alter the path of the shuttle to be exchanged. Following the altered path the to-be-exchanged shuttle impinges on a shuttle stored in a storage channel and drives it into the reentrant loop while the to-be-exchanged shuttle is retained in the storage channel. The enclosing wall of the shuttle exchanger defines part of the reentrant lumen and includes therein the channel selector , the shuttle storage channel , a bypass channel , and a collector section
