Title

Titles differ between systems:

IPC: Systems essentially incorporating special features for controlling the speed or the actuating force or speed of an output member

CPC: Systems essentially incorporating special features for controlling the speed or actuating force of an output member

Full Title

Full titles differ between systems:

IPC:

Servomotor systems without provision for follow-up action > Systems essentially incorporating special features for controlling the speed or the actuating force or speed of an output member

CPC:

Servomotor systems without provision for follow-up action; (F15B3/00 takes precedence) > Systems essentially incorporating special features for controlling the speed or actuating force of an output member

Of 4 combined children, 3 exist in both systems.

1 codes are CPC-only extensions.

2 shared codes have differing titles between IPC and CPC.
