Conjugate devices, i.e. devices having at least one port decoupled from one other port

Introduced: July 1974

Full Title

Full titles differ between systems:

IPC:

Coupling devices of the waveguide type > Coupling devices having more than two ports > Conjugate devices, i.e. devices having at least one port decoupled from one other port

CPC:

Coupling devices of the waveguide type > Coupling devices having more than two ports (H01P5/04 takes precedence) > Conjugate devices, i.e. devices having at least one port decoupled from one other port

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1974.
