DEFINITION

Classification: 242/444.1

Dielectric and conductive layers (e.g., capacitor):

(under subclass 444) Subject matter wherein the winding materials include alternate electrically conductive and dielectric strips wound on the core in superposed convolutions usually to form an electrical capacitor (condenser).

(1) Note. Patents disclosing a capacitor winding machine or method without details specific to conductor or dielectric winding are classified as generic winding machines provided for later in this class.
