ABSTRACT:
A rotary drum comprises a hollow cylindrical outer member, a coaxial hub, and a plurality of spokes pivotally connected to the outer member and to the hub, all the spokes being aligned at the same oblique angle to the radius at the respective connections to the hub. Thermal expansion of the outer member relative to the spokes is accommodated by rotation of the outer member relative to the hub and a consequent change in the oblique angle, so minimizing thermally induced stresses in the spokes. The drum may be used in the production of a metal by deposition from the vapor phase onto the outer surface of the drum.
