Full titles differ between systems:
IPC:
Gearings for conveying rotary motion with variable gear ratio, or for reversing rotary motion, by friction between rotary members > characterised by the use of a magnetisable powder or liquid as friction medium between the rotary members
CPC:
Gearings for conveying rotary motion with variable gear ratio, or for reversing rotary motion, by friction between rotary members (control of change-speed or reversing-gearings conveying rotary motion F16H59/00 - F16H63/00) > characterised by the use of a magnetisable powder or liquid as friction medium between the rotary members
