116Karl Fischer titration — is a classic titration method in analytical chemistry that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer.Coulometric titrationThe main… …
117History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… …
118Electrolyte — This article is about the ionic solution. For the R.E.M. song, see Electrolite. In chemistry, an electrolyte is any substance containing free ions that make the substance electrically conductive. The most typical electrolyte is an ionic solution …
119Tube socket — Left to right: octal (top and bottom view), loctal, and miniature (top and side view) sockets. An early transistor socket and an IC socket are included for comparison. Tube sockets are electrical sockets into which vacuum tubes (also known as… …
120Beam tetrode — The problem of secondary emission in the tetrode tube (valve) was solved by Philips/Mullard with the introduction of a suppressor grid to produce the pentode construction. Since Philips held a patent on this design, other manufacturers were keen… …
