DIFF Subgroup
H01J 1/04 Liquid electrodes, e.g. liquid cathode
Introduced: September 1968
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 > Main electrodes > Liquid electrodes, e.g. liquid cathode
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) > Main electrodes > Liquid electrodes, e.g. liquid cathode
IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
