DEFINITION

Classification: 336/55

(under the class definition) Inductor devices wherein means are provided for modifying or for controlling the temperature of the inductor device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

179, for inductor devices whose inherent construction is such as to maintain their inductance at a constant value, or which permits their inductance to vary in a predetermined manner with changes in temperature of the device.

SEE OR SEARCH CLASS

62, Refrigeration, appropriate subclasses for miscellaneous refrigeration apparatus, particularly

259.1+, for refrigeration means installed in structures having other functions. 165, Heat Exchange, appropriate subclasses for heat exchange apparatus combined with a device to be cooled or heated thereby, if no structure of such device is included other than that necessary for cooperation with the heat exchange device.

174, Electricity: Conductors and Insulators,

15.1+, for a mere housing, casing or envelope for an electrical device where no significant structure of the device is claimed with means for modifying the temperature of the device.

310, Electrical Generator or Motor Structure,

16, and 52+ for reciprocating and rotary dynamoelectric machines, respectively, with cooling or temperature modification means.

315, Electric Lamp and Discharge Devices: Systems, particularly

50, for combined structure of a space discharge device and impedance means, which means may be an inductor, and which means is constructed to modify the temperature of the load device.

331, Oscillates,

69, and 70 for oscillator systems with means for modifying or controlling the temperature of the oscillator or an element, such as a tank circuit inductor, of the oscillator.

454, Ventilation, appropriate subclasses for miscellaneous ventilating apparatus.
