(under subclass 75) Devices in which the member is movable about an axis of rotation.
(1) Note. An illustrative example is: [figure]
SEE OR SEARCH THIS CLASS, SUBCLASS:
120+, for inductor devices having relatively movable coils and a core, a coil and a core being relatively movable as a unit about an axis of rotation.
122+, and the subclasses specified in the Notes thereto for inductor devices having relatively movable coils, one of the coils being movable about an axis of rotation.

74, Machine Element or Mechanism, 10+, and the subclasses specified in the Notes thereto for mechanical mechanism for rotating a shaft including such mechanism designed for use with an adjustable inductor device. Also see the search notes to subclass 10 of Class 74 for the classification of other rotary shaft moving mechanism and for the line between Class 336 and Class 74.
310, Electrical Generator or Motor Structure,
105+, for induced or eddy current magnetic field type of torque transmitting clutch or brake which have a rotating short-circuited or conducting disc member, and subclasses 210+ for dynamoelectric machines with secondary windings or conductors which may include such of the short-circuited coil or disc conductor type.
324, Electricity: Measuring and Testing,
137+, for meters with eddy current rotors.
335, Electricity: Magnetically Operated Switches, Magnets, and Electromagnets,
225, for magneto-mechanical motive devices with relatively,
movable members of the induced current type, (e.g., rotary disk); and subclass 226 specifically for such with short-circuited coils.
