.~.~.~ Insulation formed and hardened in situ (e.g., molded)
DEFINITION
Classification: 338/248
(under subclass 247) Subject matter wherein the insulation is formed between the resistance element and 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 later 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 247, 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.
250, for resistors generally whose element is in insulation with a 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.
