Subject: Is claim of being able to put more air at 15 psi into a vessel of 200 psi?

At the U.S. patent office web site, patent number 2,030,759 (1934, I believe) 
Bob Neal claims to have a compressor that will pump more air at 15 psi into a 
vessel of 200 psi. Is this legitimate? If not, why would his patent be 
awarded? Is it feasible?

I originally found this information at Scott Robertson's website "Pneumatic 
Options" and confirmed it at the U.S. patent office website.

Thank you for confirming this.
