Luminescent screens; Selection of materials for luminescent coatings on vessels

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 > Screens on or from which an image or pattern is formed, picked-up, converted, or stored; Luminescent coatings on vessels > Luminescent screens; Selection of materials for luminescent coatings on vessels

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) > Screens on or from which an image or pattern is formed, picked-up, converted, or stored; Luminescent coatings on vessels > Luminescent screens; Selection of materials for luminescent coatings on vessels

IPC and CPC are identically structured here. All 7 subcodes exist in both systems.
