ABSTRACT:
Sound waves are utilized to apply torque to a body in an enclosure of square cross section, by driving two transducers located on perpendicular walls of an enclosure, at the same frequency but at a predetermined phase difference such as 90.degree.. The torque is a first order effect, so that large and controlled rotational speeds can be obtained.
