Abstract
A processing wall is made part of a boundary of a continuous re-entrant lumen, another part of which is a return section. A free, wall conditioning shuttle circulates around this lumen, clearing accumulated material from the processing wall and returning through the return section to circulate again. While the shuttle is in the return section it blocks flow through the return section and while the shuttle is circulating through the processing wall a blocking structure blocks flow through the return section.
