Full Title

Full titles differ between systems:

IPC:

Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion > without gears having orbital motion > exclusively or essentially using gears that can be moved out of gear

CPC:

Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion (speed-changing or reversing mechanisms F16H59/00 - F16H63/00) > without gears having orbital motion > exclusively or essentially using gears that can be moved out of gear

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
