A signal transmission device comprises a high-frequency signal waveguide. The storage system also has a control unit and managing a plurality of virtual volumes. The controller can also generate a valve control signal based on a measured pressure at a particular pressure sensor during a second mode of operation. Said storage tank including a vapor port and a liquid port. Accordingly, in response to operation of the actuators the posts of each of the clevis-shaped members shift in unison to center and clamp the workpiece at the workstation. The motor output shaft, intermediate shaft and final output shaft are mounted on bearings at fixed centers on the frame plates and the motor and intermediate shaft are interconnected by a stretchable flexible drive belt reeved over respective drive pulleys mounted on the motor output shaft and the intermediate shaft.
