I believe the vacuum tubes on the headwheel guide block and base are
sealed with Eastman 910.

The Kodak chemist that discovered Cyanoacrylate's adhesive properties
during World War II died in Kingsport, Tennesee, Saturday.

Harry Wesley Coover, Jr.had 460 patents and introduced more than 320 new
products for Kodak, and retired in 1984 as a Kodak vice president.
Coover was 94.

During wartime research on clear plastic gunsights, he discovered the
adhesive while working with acrylates. Unfortunately for Coover's
project, the gunsights stuck to everything they came in contact with.

The substance found a use in 1951, when another Kodak researcher used it
in a lens experiment and found it impossible to separate two lenses he'd
coated with Cyanoacrylate and then pressed together.

Cyanoacrylate came to market in 1958 as Eastman 910.

Later known as SuperGlue, Coover's patent had expired by the time the
sticky stuff became a household name.

Coover was awarded the National Medal of Technology and Innovation last
year by President Obama. He was inducted into the National Inventor's
Hall of Fame in 2004.

What uses for Cyanoacrylate did manufacturers and engineers find on Quad
machines?
