52.~ Granular, powdered, or transversely stacked resistance element


DEFINITION

Classification: 338/52

(under subclass 51) Subject matter wherein the resistance element is granular or powdered in form or is formed as a plurality of layers or other distinct masses stacked or piled transversely to the direction of current flow through the resistance element; i.e., so that the current flowing through the resistance element will flow from mass to mass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

54, for resistors with cooling gas or liquid circulation, and having granular powdered or transversely stacked elements.

99+, for mechanically variable resistors including surfaces pressed together for adjustment purposes, e.g., compressible type; and subclass 115 for such resistors generally whose elements are in piled or stacked layers.

204+, for resistors generally whose elements are piled or stacked between terminals.

223+, for resistors having granular or powdered elements.
