Use the links above or do an advanced search in ppubs for:
(382/224.ccls. or 382/225.ccls. or 382/226.ccls. or 382/227.ccls. or 382/228.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.
