296  DF  HELICAL OR WOUND RESISTANCE ELEMENT {7}
298.~ Compound helix or winding


DEFINITION

Classification: 338/298

(under subclass 296) Subject matter wherein the resistance element is formed in two or more distinct helical or winding patterns, as a coiled wire resistance element being, in turn, helically wound on a cylindrical form.

SEE OR SEARCH THIS CLASS, SUBCLASS:

287+, for compound or multiple zigzag resistors, and especially subclass 286, where one of the winding patterns is helical.

297, for compound helically wound resistors, where one of the winding patterns is flattened.

299, for resistors formed with plural supported helices or windings.
