Use the links above or do an advanced search in ppubs for:
(429/82.ccls. or 429/83.ccls. or 429/84.ccls. or 429/85.ccls. or 429/86.ccls. or 429/87.ccls. or 429/88.ccls. or 429/89.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.
