CPC: in which a fluid is used (fluid couplings allowing continuous slip F16D31/00 - F16D35/00)
Full Title
Full titles differ between systems:
Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > in which a fluid is used
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) > in which a fluid is used (fluid couplings allowing continuous slip F16D31/00 - F16D35/00)
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
