Schawlow and Townes had already applied for a patent on the laser, in July 1958. Their patent was granted on March 22, 1960. Gould and TRG launched a legal challenge based on his 1957 notebook as evidence that Gould had invented the laser prior to Schawlow and Townes's patent application.
Theodore Harold Maiman (July 11, 1927 – May 5, 2007) was an American engineer and physicist who is widely credited with the invention of the laser. [1] [2] [3] [4 ...
A Crosley IcyBall with cold side ball on left, hot side ball on right. Icyball is a name given to two early refrigerators, one made by Australian Sir Edward Hallstrom in 1923, and the other design patented by David Forbes Keith of Toronto (filed 1927, granted 1929), [1] [2] and manufactured by American Powel Crosley Jr., who bought the rights to the device.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of ... When the laser was first invented, ...
Crosley's "Icyball" was an early non-electrical refrigeration device. The unit used an evaporative cycle to create cold, and had no moving parts. The dumbbell shaped unit was "charged" by heating one end with a small kerosene heater. Crosley's company sold several hundred thousand Icyball units before discontinuing its manufacture in the late ...
