ABSTRACT:
A swirl or pitch changing chamber (16) is interposed at the convergence of a plurality of divergent pneumatic forwarding tubes (11, 12) and communicates with the tubes (11, 12). In the chamber (16), a transporter capsule (15) is caused to perform a complex motion, the motion being predominantly a pitch changing translation, by use of mechanical, electromagnetic, magnetic and/or pneumatic forces caused to act on the capsule (15), thereby accomplishing a desired change in the direction of longitudinal travel of the capsule (15). The chamber (16) is defined by an enlargement in the transverse dimension of the tubes (11, 12), the dimensions of the chamber (16) being sufficient to accommodate the complex motion.
