Full Title

Full titles differ between systems:

IPC:

Fluid-actuated clutches > in which the fluid actuates a piston incorporated in the clutch > the clutch having friction surfaces > with clutch members exclusively moving axially > with flat friction surfaces, e.g. discs > with more than two discs, e.g. multiple lamellae

CPC:

Fluid-actuated clutches > in which the fluid actuates a piston incorporated in, the clutch (F16D25/02 takes precedence) > the clutch having friction surfaces > with clutch members exclusively moving axially > with flat friction surfaces, e.g. discs > with more than two discs, e.g. multiple lamellae

No child classifications to compare. This is a leaf node in both IPC and CPC.
