Use the links above or do an advanced search in ppubs for:
(348/65.ccls. or 348/66.ccls. or 348/67.ccls. or 348/68.ccls. or 348/69.ccls. or 348/70.ccls. or 348/71.ccls. or 348/72.ccls. or 348/73.ccls. or 348/74.ccls. or 348/75.ccls. or 348/76.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.
