I think that was a follow-on patent to make the single-character
NIMO tube into a multi-character version. Some of the sales
literature shows a 4-digit display. Neat idea, but by then
7-segment LEDs were getting a lot cheaper and led to the death of
NIMO, Nixie, Numitron, and electroluminescent.
It's really amazing how many oddball (by today's standard)
technologies were used for numerical displays. Fifty years from
now, I doubt people will drool over LCD and OLED displays the way
we do with NIMO tubes....but you never know.

I should have said that it is not the actual NIMO patent
but from Industrial Electronic Engineers, lnc from which
you can start your search, sorry for any confusion.
