Theory and Techniques for Design of Electronic Digital Computers (popularly called the "Moore School Lectures") was a course in the construction of electronic digital computers held at the University of Pennsylvania's Moore School of Electrical Engineering between July 8, 1946, and August 30, 1946, and was the first time any computer topics had ever been taught to an assemblage of people.
However, due to the existence of another Eclipse Stove Company that was not affiliated with Tappan's company, the company was renamed the Tappan Stove Company in the 1920s. [ 3 ] In 1950, Tappan acquired the Los Angeles-based O'Keefe & Merritt Stove Company and used the O'Keefe & Merritt name in the western United States from then until the ...
The inside of a cavity from a Russian military radar transmitter, with the cover removed. The cavity serves as the resonant circuit of an oscillator using the triode vacuum tube inside. Parts: (1) A setscrew trimmer capacitor used to adjust the frequency (2) The top of the GS13-1 (Russian: ГС-13-1 [1]) triode which generates the microwaves
Putting a non-microwave-safe material in a microwave oven can lead to chemicals leaching into your food (not good) or the melting of the container, which can lead to burns — or, at the very ...
Pyramidal microwave horn antenna, with a bandwidth of 0.8 to 18 GHz. A coaxial cable feedline attaches to the connector visible at top. This type is called a ridged horn; the curving fins visible inside the mouth of the horn increase the antenna's bandwidth. The first modern horn antenna in 1938 with inventor Wilmer L. Barrow.
A magic tee (or magic T or hybrid tee) is a hybrid or 3 dB coupler used in microwave systems. [1] It is an alternative to the rat-race coupler . In contrast to the rat-race, the three-dimensional structure of the magic tee makes it less readily constructed in planar technologies such as microstrip or stripline .
Microwave volumetric heating has a greater penetration depth, of up to 42 millimetres (1.7 in), which is an even penetration through the entire volume of the flowing product. This is advantageous in commercial applications where increased shelf-life can be achieved, with increased microbial kill at temperatures 10–15 °C (18–27 °F) lower ...
For insulating materials (both solid and liquid), [6] probing charge dynamics with microwaves is a part of dielectric spectroscopy.Amongst the conductive materials, superconductors are a material class that is often studied with microwave spectroscopy, giving information about penetration depth (governed by the superconducting condensate), [4] [7] energy gap (single-particle excitation of ...
