Introduced: January 1980

Title

Titles differ between systems:

IPC: using single beam tubes

CPC: using single beam tubes (G09G1/26, G09G1/28 take precedence),

Full Title

Full titles differ between systems:

IPC:

Control arrangements or circuits, of interest only in connection with cathode-ray tube indicators > using single beam tubes

CPC:

Control arrangements or circuits, of interest only in connection with cathode-ray tube indicators; (cathode-ray oscilloscopes G01R13/20; ) > using single beam tubes (G09G1/26, G09G1/28 take precedence),

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1980.
