.~.~ With heat conducting or distributing path
DEFINITION
Classification: 338/159
(under subclass 118) Subject matter wherein a mass of heat conducting material usually metallic is disposed in the vicinity of the resistance element to provide a medium for transmission of the heat from the element along a desired and limited path.
(1) Note. The subject matter classified here provides a distinct and limited path for the heat passage for cooling purposes as opposed to a heat conductive casing which dissipates the heat in all directions from the element.
SEE OR SEARCH THIS CLASS, SUBCLASS:
25+, for resistors whose resistance value changes with ambient temperature.
51+, for resistors with heat dissipating projections, e.g., vanes.
226+, for resistors generally with a heat conductive casing or housing. See also (1) Note, above.
