ABSTRACT:
A driving device for slow movement vertically and rotationally comprises a cylindrical central member having the workload on the upper end, and the lower end on a thrust bearing on a float immersed in a liquid whose supply can be controlled for vertical displacement.
Chambers insulated from each other, and supplied with compressed air, surround the central member. Nozzles in the chamber walls establish fluid bearings to self-center the central member and to rotate it.
