Full Title

Full titles differ between systems:

IPC:

Details of electrodes, of magnetic control means, of screens, or of the mounting or spacing thereof, common to two or more basic types of discharge tubes or lamps > Control electrodes, e.g. grid; Auxiliary electrodes

CPC:

Details of electrodes, of magnetic control means, of screens, or of the mounting or spacing thereof, common to two or more basic types of discharge tubes or lamps (details of electron-optical or ion-optical arrangements H01J3/00) > Control electrodes, e.g. grid (for igniting arrangements H01J7/30); Auxiliary electrodes (auxiliary anodes for maintaining a discharge H01J1/36)

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
