Titles differ between systems:
IPC: using dynamo-electric devices
CPC: using dynamo-electric devices (operated by pulses G08C19/20)
Full Title
Full titles differ between systems:
IPC:
Electric signal transmission systems > using dynamo-electric devices
CPC:
Electric signal transmission systems (G08C17/00 takes precedence) > using dynamo-electric devices (operated by pulses G08C19/20)
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
