Abstract: Disclosed herein is a stator plate for a rotary bed PSA apparatus that has an exhaust slot that has first and second sections for receiving blowdown and purge exhaust gas streams, the sections being separated by a flow restriction that restricts but does not full prevent gas flow between the sections, or that has separate exhaust slots for separately receiving the blowdown and purge exhaust gas streams. Also disclosed is pressure swing adsorption (PSA) apparatus including such a stator plate, and a rotary bed PSA process using such an apparatus.

Abstract: A steering apparatus includes a rotatable steering shaft having an exterior, an input end for connecting a steering member and an output end for connecting to at least one steerable wheel of a vehicle. An electric motor is operatively connected to the steering shaft for rotating the steering shaft. The shaft is magnetized and serves as a torque sensor transducer. At least one magnetic field sensor is adjacent to the exterior of the steering shaft. The steering shaft and the at least one magnetic field sensor form a torque sensor for sensing torque applied to the steering shaft by the manually operable steering member and provide a signal to operate the electric motor to assist steering of the steering shaft by the manually operable steering member.

Abstract: The invention relates to a steering apparatus for a vehicle. It includes a housing with a steering shaft having a longitudinal axis. A first bearing is interposed between the shaft and the housing, permitting rotation of the steering shaft about the axis. There is also a first wedge-shaped member that has a thin end against the first bearing and a means for biasing the first wedge-shaped member against the first bearing to take up play between the shaft and first bearing, and play within the first bearing.
