the company effectively set the selling prices for vacuum tubes in the u.s., which were significantly higher than in europe, where lee de forest had allowed a key patent issued to him to lapse. rca was responsible for creating a series of innovative products, ranging from octal base metal tubes co-developed

with general electric before world war ii, to miniaturized nuvistor tubes used in the tuners of the new vista series of tv sets. the nuvistor tubes were a last major vacuum tube innovation, and were meant to compete with the newly introduced transistor. by , rca had completely switched from tubes to...

geissler tubes tour : click picture below for previous back to mike's electric stuff click picture below for next geissler tubes these intricate glass gas-filled tubes were made in the early s, as a scientific curiosity for use with the induction spark coils which were popular at the time. my tubes below

are all - " long. larger and more intricate tubes were made, in sizes up to ", with the glass tube formed into all sorts of twists, bows and spiral shapes. the inverter modules for cold-cathode flourescent (ccfl) lcd panel backlights work very well for powering geissler tubes, although you shouldn't...

that of atmospheric pressure. there are several types of vacuum gauges, each engineered for a specific function over a specific range of vacuum pressure (fig. ). common types (table ) include: mechanical gauges absolute pressure gauges thermocouples or pirani gauges ionization gauges (hot & cold cathode

are encountered. the source of the free conduction electrons in the device may be either thermal such as a heated filament physically associated with the cathode of the device - a hot cathode, or alternatively a simple consequence of a high voltage gradient across the device, resulting in autoemission

from the cathode. a device employing this latter method is known as a cold cathode device. in high voltage switching the presence of high voltages, and hence the possibility of large voltage gradients within devices means that the cold cathode system, quite a rarity in most other types of tubes, is...
