F16D 3/50

with the coupling parts connected by one or more intermediate members (F16D3/16 takes precedence)

Introduced: September 1968

Title

Titles differ between systems:

IPC: with the coupling parts connected by one or more intermediate members

CPC: with the coupling parts connected by one or more intermediate members (F16D3/16 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > with the coupling parts connected by one or more intermediate members

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) > with the coupling parts connected by one or more intermediate members (F16D3/16 takes precedence)

IPC and CPC are identically structured here. All 9 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.
