DEFINITION

Classification: 338/250

(under subclass 243) Subject matter wherein the insulation is formed between the resistance and the metallic sheath and hardened in this position; or wherein the insulation is formed on and hardened on the resistance element or in the metallic sheath, the other of the resistance element and metallic sheath being placed on the formed insulation.

(1) Note. In this subclass the insulation is usually molded or vitrified in position. Where the insulation is hardened in a preformed mass and then applied to the sheath and element, classification is not in this subclass, but in the generic subclass 243 above.

SEE OR SEARCH THIS CLASS, SUBCLASS:

244, and 245, for resistors whose element is in insulation with a metallic sheath, the insulation constituting a coating.

248, for a resistor whose element is in insulation with a plural part metallic sheath, the insulation being formed or hardened in situ.

269, and 275, for incased, embedded, or housed resistors not classified above, the casing or housing being formed on and hardened on the resistor, e.g., molded.
