Hazeltine was a very old radio company, going back to

Indeed; it was common to see on the label of old B&W TV sets, an
acknowledgement that certain aspects were licensed from
Hazeltine--namely, the AGC circuit. You'd often also see the same sort
of acknowledgement for Edwin H Armstrong (FM) as well as RCA.
In the 40s and 50s, I wonder if Hazeltine made more off their patents
than actually selling product.
