Medico Pipe Filter US Patent

In a recent video on the Aristocob Youtube channel, I talked about recent changes in the venerable Medico pipe filter. Because I just can't stand knowing just a little about something I went on a hunt for information about how the Medico filters came to be. Below is a pic of the first page of the US Patent that was granted to Paul H Minton in 1933 and again in 1934 as well as a couple old Medico ads. (Click pics to Biggie-Size)
