Seems perfectly visible here (at least the second) - An Upjohn patent, issued just over 40 years ago. Maybe try other sources, the other is also available and is a Centaur patent. Both seem relevant to your earlier post.

I never use USPTO's site.  It sucks.  Try freepatentsonline.com

Try searching Google, it has most patents available.
I even found mine!
