People have been worrying and
complaining about machines and computers taking away jobs from humans ever since
Whitney invented the cotton gin (probably even before then). In this advertisement
in a 1946 issue of Radio News magazine, General Electric touts the wonders
of its electronic inspection apparatus that is capable of inspecting and testing
hand grenade fuses at a rate of 4,000 per hour. The job is performed with a variety
of specialty vacuum tube types, including an x-ray generator to produce metal-penetrating
energy and a phototube to detect the resultant image. A thyratron tube provides
1/10th megavolt pulses to the x-ray tube, and sundry amplifier and rectifier tubes
decide whether the image represents a good fuse. Given the criticality of the job,
it is doubtful that too many people complained about not having the responsibility
of judging the fitness of those hand grenade fuses.

A G-E X-ray tube (1), a G-E phototube (2), a G-E thyratron tube (3), and several
G-E amplifier tubes are the "eyes and brains" of this ingenious machine.
To safeguard our fighting men, hand grenades must be flawless - every fuse must
be timed to split-second accuracy.
From the engineering laboratory of General Electric has come an automatic X-ray
inspector - the first of its kind - which checks time fuses at the incredible rate
of 4000 an hour ... with the unerring accuracy no other inspection method can even
A movable belt carries the fuses through the penetrating beam of a 100,000-volt
G-E X-ray tube which casts its glow on a fluorescent screen. A G-E phototube, or
"electric eye," inspects the glow. If constant, verdict is "O.K." If intensity changes,
powder charge is inadequate for proper timing. Instantaneously, a four-way alarm
is given ... a bell rings; a red light flashes; the imperfect fuse gets a dab of
red paint; a photo-electric meter chart records the "dud."
It is the purpose of G-E electronic tube engineers to aid any manufacturer of
electronic devices in the application of tubes. Through its nation-wide distribution
system, G. E. is also prepared to supply users of electronic devices with replacement
