Use the links above or do an advanced search in ppubs for:
(83/58.ccls. or 83/59.ccls. or 83/60.ccls. or 83/61.ccls. or 83/62.ccls. or 83/62.1.ccls. or 83/63.ccls. or 83/64.ccls. or 83/65.ccls. or 83/66.ccls. or 83/67.ccls. or 83/68.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.
