EDM Patent Book

Boy that sure was quick. I have had several people inquire relating
to the EDM Patent Book mentioned in a previous Email of mine. I hope
the following answers some of your questions.
This book is not a photo copy it is a saddle stapled book printed on
an off set press. It has lots of electrical schematic of the various
patents. The book is 29 pages long printed both sides and really
packed as the print is smaller than standard print. In compiling
the patents I strip all the non technical info on the patents out
and cut to the chase to get only the hardcore technical data in
each patent.
There are 13 patents covered, topics ranging from a 1968 patent for a
Saturable Reactor type control system for EDM to and 1989
Capacitor-Type pulse generator for EDM wire Cut. Other patents cover
Stray Gap capacitance to trigger discharge
A 1992 patent for EDM power supply
Several of the patents cover the use of MOSFET technology.
1984 patent foor Superimposed high striking voltage power supply, etc
etc.
I will try and get a photo shot of the book tonight and post a few
photos on the list tomorrow.
I can accept Pay Pay or money order. All fund must be in U.S. dollars
