    See the patent, it has some clues about amounts. I can't be sure this is 
what Kodak uses in Microdol-X but it looks very possible. 
    There are two good sources of U.S. patents. One is the U.S. Patent and 
Trade-Mark Office at:
http://www.uspto.gov   the other is the new Google patents search. Go to Google 
and type Google patents in, it will list the web site first. The Google site 
has the advantage of allowing text searches for any patent where the patent 
office site allows them only for patents issued after 1975. I found this one by 
searching for Richard W. Henn, one of Kodak's top researchers.
