Use the links above or do an advanced search in ppubs for:
(473/35.ccls. or 473/36.ccls. or 473/37.ccls. or 473/38.ccls. or 473/39.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.
