Use the links above or do an advanced search in ppubs for:
(235/462.43.ccls. or 235/462.44.ccls. or 235/462.45.ccls. or 235/462.46.ccls. or 235/462.47.ccls. or 235/462.48.ccls. or 235/462.49.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.
