Marked: "3611, Pat. in USA, 3-20-7; 10-8-20; 4-22-24; 6-16-25". Early cathode ray tube with horizontal and vertical deflection plates. Plates are connected directly to filament stem which is cracked ...

A DIFFRACTION pattern was obtained by passing a cathode ray beam through a thin sheet of mica, with an apparatus similar to that used by G. P. Thomson in his interesting experiment on the diffraction ...

APPLICATIONS of the sealed-off cathode-ray XX tube to the field of radio have been previously well treated, so the author gains by concentrating on other applications, which are shown to be wide and ...

Scientists worked with electricity long before they understood that current was made of electrons. The cathode tube was a prime example. By switching on some voltage, scientists could make fluorescent ...
