What happened
during these years?
The
Neutron discovered - 1932
James
Chadwick discovered a particle with almost the same
mass as a proton but with no electrical charge. Neutrons were
produced by bombarding atoms, so presumably the neutrons
existed as part of the massive nucleus
Color Cartoon Film Developed - 1932
Technicolor finally contracts its three-color process to Walt
Disney
for use
in cartoons after Disney exacts a promise that
no other cartoon
producers be
permitted to use it for three
years. The other cartoon producers
suddenly see
the value
of color and start using the otherwise-abandoned two-color
Technicolor processParking Meter -
1932
Carl C.
Magee, of Oklahoma City, Okla., is generally credited
with originating the idea. As head of the city's chamber of
commerce, Magee hoped the meters would free up parking
spaces for local businesses
Improved
Electron Microscope - 1933
Ernst
Ruska A new electron microscope was invented, which
used
a condenser lens to focus a beam of electrons onto the
object
being viewed. This allowed the magnification to increase
to x12 000
FM Radio -
1933
Edwin Howard Armstrong
He showed a practical
FM system to
David Sarnoff, president of RCA. Sarnoff experimented with
the new technique but abandoned it because it meant too
radical a change in radio systems. Armstrong finally launched
his own FM system. After WW-II he fell into a quicksand of
lawsuits with RCA over FM patent rights
First Drive In Theater - 1934
Radar Developed - 1935
By:
Sir Robert Watson-Watt. Watt developed the first radar
system called a Radio Direction Finding System
Richter
Scale - 1935
Charles
F. Richter and Beno Gutenberg -The
original magnitude
scale of Richter was introduced for the purpose of providing an
objective measure of the energy of each earthquake in the initial
listing of earthquakes in the southern California region compiled
by the Seismological Laboratory in Pasadena.
Heart-lung machine - 1935
John
Heysham Gibbon
VHF Electronic Television - 1935
Nylon Patented - 1937
Wallace Carothers an organic chemist developed what
he called
Fiber 66.
The name was later changed to nylon by Dupont who
was granted the
patent.
Binary Calculator - 1937
George R. Stibitz
His first calculator
was a basic two-digit binary
adder. However, in the next year he was able to build a
calculator for complex arithmetic Teflon Invented -
1938
The material known as Polytetraflouroethylene resin was
created by
Roy J.
Plunkett for the Dupont Company.
Modern Helicopter developed- 1939
Aeronautical
engineer Igor Sikorsky created the first
successful helicopter
Automatic clutch built- 1939
Color Television - 1940
Based on a
system invented by Englishman John Baird in
1928, it was developed by CBS's Peter Goldmark in 1940.
A spiraling, perforated wheel was at the heart of this early
color television. A camera scanned images as the revolving
color wheel spun in front of it. It then transmitted three fields
- red, blue, and green, in sequence
Aerosol can Made- 1941
Lyle
D. Goodhue introduced... used to propel insecticide
Xerography Patented -
1942
The process for duplicating documents was patented by
Chester
Floyd Carlson. His machines weren't successful
however until 1947,
when the Halold Company in New
York licensed the technique. The
later became known
as Xerox. |
