Use the links above or do an advanced search in ppubs for:
(75/10.23.ccls. or 75/10.24.ccls. or 75/10.25.ccls. or 75/cr.ccls. or 75/co.ccls. or 75/cu.ccls. or 75/fe.ccls. or 75/mn.ccls. or 75/ni.ccls. or 75/ti.ccls. or 75/10.26.ccls. or 75/zr.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.
