Abstract
The system comprises a stationary drum with at least one end having a large open area, and a coaxial, rotatable cylinder of larger diameter than the stationary drum mounted for rotation about the stationary drum. The stationary drum has a plurality of circumferentially-separated, longitudinally-extending sets of gas baffles on its outside surface and a plurality of circumferentially-separated, longitudinally-extending sets of inwardly-extending louvers adapted to direct gas in an axial direction inside the stationary drum. First sealing members and circumferentially-separated second sealing members each extend across the annular space between the stationary drum and the rotatable cylinder to divide the annular space into two different pressure zones.
