(under the class definition) Subject matter where the lamp or discharge device has a magnetic device associated therewith.
(1) Note. Many of the devices in this and the indented subclasses are discharge devices in which the magnetic field is designed to influence the space discharge but these subclasses are not limited to such devices.
(2) Note. This and the indented subclass includes devices in which an electrode generates the magnetic field, such as having an electrode made in coil form to generate the magnetic field.
(3) Note. Where the lamp or discharge device is provided with an envelope, the magnetic field generating means may be within or without the envelope.
(4) Note. See the class definition for the classification of deflection and focusing magnets.
(5) Note. The magnetic means may be an electromagnet connected in circuit with an electrode. A mere conductive connection is not sufficient circuit to exclude the organization from Class 313.
