Well, this might get some dander up amongst the believers that
Watson-Watt is "the Father of Radar." In the December 1957 edition
of Popular Electronics, Col. William R. Blair was given that honored
designation based on his work on a pulse-echo method of direction
finding in the 1920s. The Wikipedia entry for Col. Blair refers
to him more specifically as the "Father
of Army Radar." Watson-Watt
William R. Blair was awarded U.S. patent #2,803,819,
titled "Object Locating System," on August 20, 1957 - a full 13
years after the patent application was submitted.
Father of Radar Gets His Reward
from Patent Office
U. S. Government finally recognized the daddy of radar by granting
a patent to Col. William R. Blair (Ret.), above, right, who conceived
the pulse-echo method of direction finding prior to 1930. It was
developed during the 1930's at, the Signal Corps Laboratories in
Fort Monmouth, N. J. In 1937 a prototype, SCR-268, radar system
(below) was demonstrated for the Secretary of War and Members of
Congress. Plans for this set were turned over to manufacturing companies
so that they could build radar equipment for the U. S. Army.
Due to the high degree of secrecy surrounding the development of
radar, a patent application was not filed by the Army Signal Corps
until 1945, and since then the Patent Office has had the matter
under consideration. This radar patent is considered to be as important
to the military as the first U. S. patent issued on the telephone
was to commercial communication.
SCR-268 Radar System
oscilloscope Shadow-Screen manufactured by Van-Dee Products, Laguna
Beach, Calif., is said to end the need for subdued light or an oscilloscope
hood. It consists of hundreds of small, hexagonal openings that
serve as individual shadow boxes, shutting off glare. The shape
of the openings permits observation from any point within 45° of
face-on position. Note contrast in photo above.
Lift-A-Dor (not the luscious lady below, but what she's holding)
is a new R/C system for opening garage doors from your car. If you
should ever want to put the car away with her around, you'll find
that a simple touch of the button she's holding will unlock the
door, open it and turn on the garage lights. Another push will close
and lock the door, and turn out the lights. Made by Alliance Manufacturing
Co., Inc., Alliance, Ohio, the device works on a limited-range low
frequency which prevents false activation by stray signals.
