8, for formation of particulate material from a liquid or molten mass by means of centrifugal force.
68, for rotation to produce frictional heat.
69+, for processes which pertain to agitating by plural sequential rotations in reverse directions; however, such patents should be crossed herein where applicable, depending on the time of duration of said rotation periods in one direction.
