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.
