Unfortunately, patents can only be searched by number before 1976, so other resources are needed to identify the number of a patent before it can be viewed.  I am interested in learning more patent numbers related to Grandpa's colleagues and other important workers.

 

Since the patent titles are often cryptic and broad, I have added brief descriptions below each one.
