(under the class definition) Subject matter wherein the resistance element is formed of a plurality of layers of resistance material such as discs or buttons, piled or stacked between the terminals, the layers being electrically connected in series together and in series with the terminals.
(1) Note. Subject matter found in this subclass consists essentially of a plurality of plates or disks of resistance material piled or stacked such that the surfaces are in electrical contact or electrically connected. The plates or disks used to construct a resistor under this subclass need not be of the same resistance material.
