Full Title

Full titles differ between systems:

IPC:

Gas-filled discharge tubes with solid cathodes > Details

CPC:

Gas-filled discharge tubes with solid cathode (H01J25/00, H01J27/00, H01J31/00 - H01J41/00 take precedence; gas filled spark gaps H01T; Marx converters H02M7/26) > Details

IPC and CPC are identically structured here. All 10 subcodes exist in both systems.
