A new numerical indicator tube, ´Nixie´

The development of a new electronic numerical indicator by the Burroughs Research Center and the Electronic Tube Division of Burroughs is described. The new numerical indicator, "Nixie," is a 10-digit gas indicator tube which provides an essentially two-dimensional in-line numerical readout with a wide angle viewing characteristic. The tube is approximately 1" in height and diameter, mounted on a 13 pin stem. The numerical assembly comprises ten "cathodes" configurated to represent the ten basic digits with a common anode. The cathodes may be selectively energized. The resultant gas discharge will make only the selected number distinctly visible to the observer.
