Title

Titles differ between systems:

IPC: by self-adjusting means

CPC: by self-adjusting means (F01D11/12 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Preventing or minimising internal leakage of working fluid, e.g. between stages > for sealing space between rotor blade tips and stator > Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing > by self-adjusting means

CPC:

Preventing or minimising internal leakage of working-fluid, e.g. between stages (sealings in general F16J ) > for sealing space between rotor blade tips and stator (specially-shaped blade tips therefor F01D5/20) > Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing (rotors with blades adjustable in operation F01D7/00) > by self-adjusting means (F01D11/12 takes precedence)

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1995.
