296  DF  HELICAL OR WOUND RESISTANCE ELEMENT {7}
300.~ Element forms a coating


DEFINITION

Classification: 338/300

(under subclass 296) Subject matter wherein the helical resistance element constitutes a helical coating on an

insulating base or support.

SEE OR SEARCH THIS CLASS, SUBCLASS:

195, for resistors which may be varied or adjusted by removing and/or adding material, the resistance element being formed as a coating.

292, for zigzag or sinuous shaped resistors whose elements form coatings.

308+, for resistors generally whose elements are formed as a coating on a base. See also the Search Notes under subclass 308.

SEE OR SEARCH CLASS 336, Inductor Devices,

200, for inductor coil structure comprising a printed conductive coating on a base.

428, Stock Material or Miscellaneous Articles,

195+, for a plural layer product having a nonuniform coating, impregnation or bond which may be helical in pattern and subclass 222 for a plural component product in which one of the components may be helical, and in which the products above may involve resistance materials.
