Introduced: September 1968

Title

Titles differ between systems:

IPC: Blade-carrying members, e.g. rotors

CPC: Blade-carrying members, e.g. rotors (rotors of non-bladed type F01D1/34; stators F01D9/00 )

Full Title

Full titles differ between systems:

IPC:

Blades; Blade-carrying members; Heating, heat-insulating, cooling, or antivibration means on the blades or the members > Blade-carrying members, e.g. rotors

CPC:

Blades; Blade-carrying members (nozzle boxes F01D9/02); Heating, heat-insulating, cooling or antivibration means on the blades or the members > Blade-carrying members, e.g. rotors (rotors of non-bladed type F01D1/34; stators F01D9/00 )

CPC subdivides this area 2x more granularly than IPC with 7 additional codes.

7 codes are CPC-only extensions.

3 shared codes have differing titles between IPC and CPC.
