in which two members of non-uniform effective diameter directly co-operate with one another

Introduced: September 1968

Full Title

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 > without members having orbital motion > Gearings providing a continuous range of gear ratios > in which two members of non-uniform effective diameter directly co-operate with one another

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) > without members having orbital motion > Gearings providing a continuous range of gear ratios > in which two members of non-uniform effective diameter directly co-operate with one another

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