DEFINITION

Classification: 314/11

(under subclass 10) Subject matter wherein an electrical circuit in shunt is completed about the discharge device or some part thereof.

(1) Note. In many of the devices in this subclass the shunt circuit is placed about only the regulating mechanism, such as the magnet coils.

(2) Note. The shunt circuit is usually of lower resistance than the resistance of the discharge device and/or the part around which it is completed and is often a "short circuit", but it may be of higher resistance.
