Use the links above or do an advanced search in ppubs for:
(714/738.ccls. or 714/739.ccls. or 714/740.ccls. or 714/741.ccls. or 714/742.ccls. or 714/743.ccls. or 714/744.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.
