(under subclass 118) Subject matter in which the portion of the center electrode which is encased by the insulating core structure consists of more than one part.
(1) Note. For the purpose of classification in this subclass, necessary terminal structure immediately adjacent the end of the insulator shall not be considered to be one of the aforementioned parts, nor shall a coated or covered wire (as, for example, in the cored rod) be considered to be plural parts for classification in this subclass.
(2) Note. The parts may be physically united as by welding a rod of one metal to a rod of another metal.
