The text under the picture of the
TV says, "Progressive research, like that which
gave us the Graphechon tube, accounts for the superiority of RCA Victor's new 1950
home television receivers."
Ever heard of the revolutionary
Graphechon Tube, by RCA? Neither had I, until I saw it mentioned in an ad for RCA
televisions in a 1950 edition of The Saturday Evening Post. My curiosity
was piqued enough to do some research.
First, here is the text of the ad:
"Scientists at RCA Laboratories work with split-seconds
of time too infinitesimal for most of us to imagine. Their new electron tube, the
Graphechon, makes it possible.
For instance, in atomic research, a burst of nuclear
energy may flare up and vanish in as little as a hundred-millionth of a
second. The Graphechon tube oscillograph, taking the pattern of this burst from
an electronic circuit, "remembers" what happened - and re-creates it in a slow motion
image which can last for a minute and a half. Scientists may then observe the pattern
of the burst at leisure... measure its energy and duration... gain new and useful
information about the behavior of the atom.
With the Graphechon we can now watch fleeting phenomena
which occur at random, outside our control. It not only applied to nuclear research,
but also to studies of electric current... or in new uses of radar and television.
Like so many products of RCA research, the Graphechon widens man's horizons."
According to Answers.com, this is the definition
of a Graphechon Tube:
"(graf′ eh kän)
A storage tube having two electron guns, one for writing and the other for reading
and simultaneous erasing, on opposite sides of the storage medium, which consists
of an insulator or semiconductor deposited on a thin substratum of metal supported
by a fine mesh."
Here is a photo of an actual Graphechon Tube, on the LampsEtTubes.info website. Look at the
bottom of the page.
"The GRAPHECHON is a charge storage tube intended for data-processing applications
where signal information must be transformed continuously from one time base to
another. Both guns have electrostatic focus and utilize magnetic deflection. Total
length : 47.8 cm (18.80 in)."
