...Dentist Sidney Bernard Finn of the University of Rochester fed a group of 90 rats a "caries-producing diet" of coarsely-ground corn. A second group of 45 rats, living on the same diet, had their teeth bathed in a weak mixture of potassium fluoride in water once a day. Results: 1) all the rats in Group I had large cavities; 2) the rats in Group II "showed a 70% reduction in dental decay"; 3) 13 of the rats in Group II had no cavities. The reduction was "not mainly in the size of the cavities, but in the number...

Invented by Budd's Chief Engineer Colonel Earl James Wilson Ragsdale, onetime professional Army officer, the "Shotweld" machine is a foolproof, delicately balanced electrical device that can be operated by unskilled labor. In less than the winking of an eye (1/20 of a second) it sends a stabbing electric current through overlapping sheets, tacks them securely without burning or over-melting, which would cut their structural strength. It also keeps track of its performance. Each weld is recorded on a tape and when the "Shot-weld" machine makes a bad one it rings a bell...
