Use the links above or do an advanced search in ppubs for:
(60/632.ccls. or 60/633.ccls. or 60/634.ccls. or 60/635.ccls. or 60/636.ccls. or 60/637.ccls. or 60/638.ccls.)
This will show what classes derive from the input. Ex: entering 43/42.24 shows the derived classes and the search that can be used to find patents or patent applications in those subclasses.
