5Gas-filled tube — See also: Gas discharge lamp A gas filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature resistant envelope. Although the envelope is typically glass, power tubes often use… …
6Knob and tube wiring — (sometimes abbreviated K T) was an early standardized method of electrical wiring in buildings, in common use in North America from about 1880 to the 1930s. [Terrell Croft and Wilford Summers (ed), American Electricans Handbook, Eleventh Edition …
7Video camera tube — In older video cameras, before the mid to late 1980s, a video camera tube or pickup tube was used instead of a charge coupled device (CCD) for converting an optical image into an electrical signal. Several types were in use from the 1930s to the… …
8Hittorf tube — Hit torf tube (Elec.) (a) A highly exhausted glass tube with metallic electrodes nearly in contact so as to exhibit the insulating effects of a vacuum. It was used by the German physicist W. Hittorf (b. 1824). (b) A Crookes tube. [Webster 1913… …
9discharge tube — a vessel of insulating material (usually glass) provided with metal electrodes which is exhausted to a low gas pressure and permits the passage of electricity through the residual gas when a moderately high voltage is applied to the electrodes …
