When I look at a photograph of
ancient buildings, bridges, and other constructs that required years of planning
and labor to complete, I think of how unfortunate it is that a history of drawings
and/or paintings do not exist that document the construction process that went into
it. Other than more contemporary renditions of what an artist thinks the sites of
the Great Pyramids, the Parthenon, the Great Wall of China, etc., might have looked
like as workers (often slaves) and engineers progressed throughout the projects,
very few instances exist.
I also wish to see the off-site manufacturing of columns and pillars, carved wooden
and stone facades, stained glass windows and decorations, furniture, pottery, swords
and cannons, and all the things that make up the entirety of the project. Let us
also see renderings of the transportation of those components to the worksite. Once
the photographic process was invented, we slowly but surely were treated to such
documentation of construction history. It is nice to see the faces of the people
who helped to build the modern world, and it would be nice to see those who built
the ancient world. This advertisement by the Sangamo Electric company's factory
is what I would like to see from the workshops of craftsmen of yore.
Here are a few more examples of Samgamo advertisements in the
September
and December
1949, May 1950,
April
1954, and June
1956 issues of Radio & Television News.
Sangamo Electric Company High Reliability Capacitors
Separate facilities are maintained for the exclusive processing
and manufacture of high reliability capacitors. Only specially trained, highly skilled
operators, who wear special clothing to prevent any possible source contamination,
work here.
Oil-filled capacitors are subject to vacuum under elevated temperatures,
then are individually examined to insure complete hermetic seal.
To produce capacitors free from any possibility of latent defects, for use in
the most critical applications, the Sangamo Electric Company has recently intensified
its high reliability program of fabrication and inspection methods.
Incoming materials are rigidly inspected to meet stringent high reliability standards
and are stored in areas where temperature, humidity and dust are controlled at all
times.
Complete production histories are kept on the basis of small capacitor lots.
X-raying of individual units, heat tests, vibration tests, altitude tests, and total
destruction tests of a given percentage of all finished units assure components
with an extremely low AQL. Testing facilities and resultant performance characteristics
are far in excess of military specifications. Specify these high reliability capacitors
for your critical applications.
High temperature test ovens are used to check insulation resistance
of Sangamo high reliability capacitors under sustained temperatures of 125°
C.
This vibration testing machine brutally punishes Sangamo high
reliability capacitors at accelerations up to 10 G's to determine their ability
to resist vibration without damage to leads or elements.
