People have been worrying and
complaining about machines and computers taking away jobs from humans ever since
Eli
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.

This electronic fuse inspector helps to
make hand grenades safe for Johnny Doughboy
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
approach.
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
tubes.
