DEFINITION

Classification: 29/610.1

Resistor making:

(under subclass 592.1) Process for making an electrical resistor and including (1) a process for making a resistor which involves metal working, (2) a process for making a resistor which involves metal working combined with an nonmetal working process such as chemical or metallurgical

and not otherwise classifiable, and (3) a process for making a resistor not otherwise classifiable.
