Abstract
A device employing frictionless bearings including a mass of superconductor material having a superconducting temperature Tc above about 77° K, magnet having an axis of symmetry being levitated from said mass of superconductor material so as to be rotatable about its axis of symmetry, and a support member attached to the magnet. The support member is driven so as to cause the magnet to rotate about its axis of symmetry. It also includes a frictionless commutator where a signal beam is intermittently interrupted by a member attached to the magnet, the support member being driven so as to cause the magnet to rotate about its axis of symmetry.
