.~ Flattened resistance element between flat layers {1}
255
.~.~ Layers coalesced or fused together
DEFINITION
Classification: 338/255
(under subclass 254) Subject matter wherein the layers are fastened to one another as by fusing, vulcanizing or other intimate bonding of all or part of the layer surfaces.
(1) Note. Where the layers are merely secured together by an adhesive such as glue, classification is not in this subclass, but in the generic subclass 254 above. Where the two layers are intimately bonded together to be integral, the structure of the casing or housing in this subclass may resemble the corresponding structure in subclass 275 below. In this subclass 255 the layers are preformed and applied to the resistance element as layers to be then fastened together. While in subclass 275 below the casing or housing is usually applied as a plastic mass and then hardened in place. Usually in subclass 275 due to the nature of the molding or hardening process the casing or housing is intimately associated with or adheres to the surface of the resistance structure which it surrounds, while in this subclass 255 this is unnecessary.
SEE OR SEARCH THIS CLASS, SUBCLASS:
212, for flexible or folding sheet or tape resistors whose casing layers are fused or coalesced together.
269, and 275, for a resistor whose casing or housing is formed on and hardened on as by molding. See also (1) Note above.
