DEFINITION

Classification: 445/46

Electrode making:

(under subclass 1) Method for fabricating or manufacturing an electrical conductor through which an electric current enters or leaves a vacuum or a fluent media.

(1) Note. For original placement within this subclass it is not only necessary that the electrode structure itself be produced without any recited assembly or disassembly operation but also that no other fabrication or manufacture of the product.
