1000 REVOLUTIONS PER SECOND!
That's the speed of newest West-
inghouse motor, producing a tool
surface speed of 7,000 feet per
minute. This 4 horsepower induc-
tion motor has a rotor only 2 inches
long, diameter 13/4 inches. West-
inghouse engineers are now devel-
oping a motor to go twice as fast.
B'R'R'R'R'R ... A polar bear would
be right at home at 200 below zero
in the Westinghouse "igloo" at
East Pittsburgh. This cold cham-
ber is 1500 times as large as the
average electric home refrigerator.
Here, Westinghouse engineers test
ice-coated circuit breakers and
other electrical switching equip-
ment,to guarantee operation under
worst winter conditions.
HIGH LIFE IS HARD on carbon gen-
erator brushes in high-flying
bombers. They used to wear down
to the pigtails in an hour or two,
at 30,000 feet. Now Westinghouse
engineers have developed a chemi-
cal treatment that keeps the brush
face lubricated at substratosphere
heights. Result: fifty-fold increase
in brush life ... enough for a dozen
raids over Berlin.
EVER SEE A MILLIONTH of an inch?
Probably you never will-but the
Electrigage can feel as little as
twelve millionths. Developed by
Westinghouse and Sheffield Cor-
poration, it can measure with a
precision equal to finding an error
ol three-quarters of an inch in a
mile. Infinitesimal movement of
gauging stylus induces a tiny cur-
rent, which is amplified 10,000
times.
AIR IS HEAVY STUFF when you start
pushing it around at 400 miles an
hour. That's why U. S. Army
needed a 40,000 horsepower elec-
tric motor to create a man-made
hurricane, for testing airplanes in
Wright Field wind tunnel. It is the
world's largest wound-rotor induc-
tion motor, designed and built by
Westinghouse engineers.
The above items are condensed
excerpts from articles in the WEST-
INGHOUSE ENGINEER, a bi-monthly
engineering review. Regular sub-
seription price-$2.00 a year. Spe-
cial price to students-.)0.
      Chemical analyses -right now!
Above is the laboratory model of the Westinghouse mass spectrometer,
which sorts out dissimilar molecules according to their mass, and does
it almost as fast as you can snap your fingers.
  The mass spectrometer provides a new way to get the quick, accu-
rate analyses that are needed to maintain precise process control. Take
the synthetic rubber industry, for example. Formerly, five men took as
long as three days to complete necessary chemical tests in the processing
of artificial rubber-which meant that the results were often too late
to be useful.
  The new electronic "chemist," the Westinghouse mass spectrometer,
now makes these tests in about 15 minutes.
  For leadership in the electrical solution of industry's problems, look
to Westinghouse. Westinghouse Electric U Manufacturing Company,
Pittsburgh 30, Pennsylvania.
