datamp has a catagory index for all the patents. ... [ snip ]
When I first connected with DATAMP, I supplied the categories for wrenches ... I started with the categories Dad & Mom used in "Antique & Unusual Wrenches," and factored in everything that had appeared in the MVWC Newsletter.
With several thousand wrench patents in DATAMP, it would be a real challenge to revise the categories & re-assign each of those patents within a "revised" category structure.
I tried to put all the "FITZALL" types into "wedge adjust" (wrenches:wrench adjustment types:wedge adjust wrenches ).
