DIFF Subgroup
F16D 3/02

adapted to specific functions

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > adapted to specific functions

CPC:

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > adapted to specific functions

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
