Note(s) This sub-class deals with (a) electrostatic generators, motors, clutches, or holding devices, (b) other non-dynamo-electric generators or motors, (c) holding or levitation devices using magnetic attraction or repulsion, and (d) arrangements for starting, regulating, braking, or otherwise controlling such machines unless in conjoint operation with a second machine.
