AN EYE TO THE FUTURE -- AN EAR TO THE GROUND
in this small brochure is a glimpse of what GM had on display at the 1933-34 World's Fair
in Chicago. As mentioned in summaries about the Chicago World's Fair, the focus was on
technology and the GM Research Laboratories had some pretty amazing stuff to show off back
There are 11 panels (pages) in the brochure
that cover the displays but we'll only highlight a couple here -- just to give you a
flavor of what was on display. Aside from mentioning the "technology" exhibits
the brochure mentions exhibits where technology was used to develop more reliable engines
It was the popularity of this exhibit that
inspired Charles F. Kettering, then Vice President of GM, to
"put-the-show-on-the-road," as it were. Boss Ket, as he was refereed to,
convinced GM board chairman Alfred P. Sloan, Jr. and public relations vice president Paul
Garrett that depression weary Americans would eagerly attend a free hometown show. And
attend they did -- in the millions!
FOUNTAIN OF COLOR
YOU BEND A RAILROAD RAIL?
|When the rays from
Ultra-Violet lights strike these fluorescent mineral rocks there is a spectacle of
glorious color which runs the full range of the rainbow. This is one of the largest and
finest collections in the world.
(Just in case you're wondering, yes, it does seem odd
that they would speak about color and use a black and white picture.)
|Bending a railroad rail is not usually a
womans job but it isnt such a task when it is only a matter of a few
millionths of an inch. A little instrument known as a telemeter indicates the deflection
caused by merely pressing the finger tips on the rail. General Motors engineers use this
telemeter to determine the exact pressure on the walls of engine combustion chambers.
A sound emitting from an organ pipe is sent down the large tube and by turning the sound
in the smaller tube to ¼ of the wave length of the 1st sound this second sound
meets the one coming from the organ pipe and stops it. This is the basic principle used by
General Motors engineers in silencing the noise formerly made by carburetors.
Water boils in a teakettle on a book. This is done by a 1600 cycle induction coil, which
causes the molecules of metal to vibrate causing intense heat. General motors Research
engineers use this scientific device in the experimental laboratories to make quick and
pure metal melts of various formulae of steel.
ELASTIC STRESS STUDY
ON A LIGHT BEAM
By making model gears and parts of a motor car out of
celluloid, then placing them in this scientific machine where their images are projected
on a screen by polarized light, General Motors engineers can determine the strength or
weakness of each design.
Music played on a phonograph record is turned into light. This
light, when projected upon a photo-electric cell receiver connected to a loud speaker, is
again turned into music. General Motors engineers use this scientific device in studying
combustion in automobile engines.
