(under the class definition) Elements comprising wheels and other rotors where the improvements claimed pertain to inertia or momentum characteristics.
(1) Note. Where additional characteristics are claimed which limit the wheel or other rotor to particular arts (as gears, vehicle wheels, centrifugal separators, turbines, dynamos, etc.), the patent will be placed with the appropriate art and cross referenced here, but the mere designation of the device by name will not exclude the same from this subclass or the indented subclasses.
