Greetings.  What is the source of the information that links the Cetron tubes branded "DeVry" with a manufacturer of movie projectors?  I have seen smaller photoelectric tubes used in 16mm film projectors for reading audio tracks, but not the larger tubes.  I also have a DeVry branded tube in my collection which was salvaged from an adjustable photoelectric relay circuit intended for educational purposes (specificlly science classes), but I cannot find any connection to film, movie, or projector production.  Also, the logos on the tubes have a striking resemblance to the DeVry Technical Institute logo from 1953.  Note that the DeVry technical institute evolved from DeForest Training school and is now DeVry University.
Cordially,
Howard
