Use the links above or do an advanced search in ppubs for:
(343/731.ccls. or 343/732.ccls. or 343/733.ccls. or 343/734.ccls. or 343/735.ccls. or 343/736.ccls. or 343/737.ccls. or 343/738.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.
