Use the links above or do an advanced search in ppubs for:
(70/372.ccls. or 70/373.ccls. or 70/374.ccls. or 70/375.ccls. or 70/376.ccls. or 70/377.ccls. or 70/378.ccls. or 70/379r.ccls. or 70/380.ccls. or 70/379a.ccls. or 70/381.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.
