Practical problems with this new electro-optical effect made Heilmeier continue to work on scattering effects in liquid crystals and finally the achievement of the first operational liquid-crystal display based on what he called the dynamic scattering mode (DSM). Application of a voltage to a DSM display switches the initially clear transparent ...
Before the development of printed circuit boards, electrical and electronic circuits were wired point-to-point on a chassis. Typically, the chassis was a sheet metal frame or pan, sometimes with a wooden bottom.
6: Electrons. 7: Metal hydroxide. Electrochemical machining ( ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and for working extremely hard materials, or materials that are difficult to machine using conventional methods. [ 1] Its use is limited to electrically conductive materials.
Electrotyping. Schematic apparatus for electrotyping. An electric current flows from the battery, through the copper anode, the electrolyte, and the coated mold. A copper film (the electrotype) grows onto the electrically conducting coating of the mold. Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly ...
Elektro was on exhibit at the 1939 New York World's Fair and was joined at that fair in 1940, with "Sparko", a robot dog that could bark, sit, and beg to humans.. Several minutes of color sound footage of Elektro in action can be seen at 33:55 in the movie, The Middleton Family at the New York World's Fair, a fully-produced hour-long movie made by Westinghouse, which showcased the Westinghouse ...

Electrical discharge machining ( EDM ), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). [ 1] Material is removed from the work piece by a series of rapidly recurring current discharges between two ...
