Use the links above or do an advanced search in ppubs for:
(436/155.ccls. or 436/156.ccls. or 436/157.ccls. or 436/158.ccls. or 436/159.ccls. or 436/160.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.
