Abstract

An automatic vortexing drive is described in which a rotatable coupling has a cuplike recess positioned off of and opening radially outward from the axis of rotation of the coupling. The coupling is positioned to intercept the lower and reaction vessels in the recess. Selective rotation of the coupling permits the vessels to pass the coupling or be engaged by the coupling and nutated.
