Title

Titles differ between systems:

IPC: with screw-spindle

CPC: with screw-spindle (F16K1/12 - F16K1/28 take precedence; actuating mechanisms with screw-spindles F16K31/50)

Full Title

Full titles differ between systems:

IPC:

Lift valves, i.e. cut-off apparatus with closure members having at least a component of their opening and closing motion perpendicular to the closing faces > with screw-spindle

CPC:

Lift valves , i.e. cut-off apparatus with closure members having at least a component of their opening and closing motion perpendicular to the closing faces ( ; diaphragm valves F16K7/00) > with screw-spindle (F16K1/12 - F16K1/28 take precedence; actuating mechanisms with screw-spindles F16K31/50)

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
