I offer a collection of 55 patents from John Scott Taggart, published between 1920 and 1927 in Great Britain or USA  (all in english).

They are busy with vacuum tube technique, radio receiving systems, amplifying system and similar topics in this field.

All patents are complete, that means contain the full text and all drawings (see example). You will get a professional overview about the inventions of Taggart which you find nowhere in the world in this good quality / completeness.

Delivery is as a zipped file with a patent collection of pdf files (not printed, not a book). You need only the wellknown free programme Acrobat Reader or a similar one to open the files. You can also print each file.

Copyright of the patent collection has only the seller!
