[NJARC] Making vacuum tubes at FIVRE in Italy, 1938

[antqradio at sbcglobal.net]

Interesting.
My Italian is non existent so the film's commentary is not helpful.

In the filmed sequence of the Sealex Machine, it looked to me like the vacuum was pulled, the tube was pinched off and then the tube was RF heated and the Getter flashed.  Perhaps that last item in the sequence was an afterthought and pinch off is actually the final step?  Like I said, I didn't understand the commentary.

FIVRE licensed patents from RCA and Tungsram, and used American machinery
to give Italy a domestic tube supply.
