Jack,
If you are interested in the text of the patent you can read it all at
http://pdfpiw.uspto.gov/.piw?PageNum...3DPN%2F0673641
If you want to read others, you can try this page to find them:
http://patft.uspto.gov/netahtml/PTO/srchnum.htm
These are pages at the government's patent office (the second is a simple search form page), not google or worse,
some other place that might try to extract monies to get information that is free for the taking.
Just thought you might like to know about the uspto government site. I've used it and find that it sucks you in reading one then another, and another...., reading about some interesting ideas that may or may not have seen the light of day.
