"Acronize" is the trade name for the antibiotic chlortetracycline, and acronized is used to describe products that have been treated with it. These five drawings are all I have of what I imagine must have been an industrial that my dad worked on somewhere along the line. Looks like the 1950s or early 60s to me.
You don't need me to break down the word "chlortetracycline" for you, but an arduous one-minute of personal online research has revealed to me that it is the first tetracycline to be discovered (1945), and is used in quantity for the treatment of bacteria in animals that some of us might eat. If you have any left over around your farm or house, cure your pig (sorry, couldn't resist that one), your cat's conjunctivitis, and of course, add it to your chicken feed.
