Dear PIUG USERS,
I'm looking for American patents of International Meehanite Metal
Co., granted in the years 1960-1980. In USPTO database I can
find three of them, but of course I can find only those which are
granted after 1976. Using the name of asignee I can't find patents
published in sixties and seventies. I would be very grateful for your
help.
