I found a couple Tucker patents on the gun turret, as seen below:
GUN CONTROL MECHANISM
Patent number: 2366072
Filing date: Jul 18, 1939
Issue date: Dec 1944

Patent number: 2408707
Filing date: Aug 16, 1941
Issue date: Oct 1, 1946
http://www.google.com/patents?id=vQdUAAAAEBAJ&printsec=abstract&zoom=4&source=gbs_overview_r&cad=0#v=onepage&q=&f=falseIt appears that most of the claims from each patent relate to gun control mechanisms. And although it may be quite useful to have automatic firearms as a part of a major kitchen appliance, I don't think the concept ever caught on, other than at Charlton Heston's house. It brings a whole new meaning to high-powered microwave ovens.
I'm not sure if the ball turret was covered by any of the Tucker turret claims, but what a strange and wonderful coincidence it would be to have this Tucker-Tremulis connection years before there ever was a Tucker '48 concept car. The following photo is from the Chicago Daily Tribune, August 7, 1943:
