DIFF Subgroup
H01P 1/165 for rotating the plane of polarisation
Introduced: July 1974
Full Title
Full titles differ between systems:
IPC:
Auxiliary devices > for rotating the plane of polarisation
CPC:
Auxiliary devices (coupling devices of the waveguide type H01P5/00) > for rotating the plane of polarisation
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 1974.
