| 1. | Thoriated electrodes are suitable for use in DCEN welding of aluminum.
|
| 2. | These usually had directly heated thoriated filament cathodes that glowed like light bulbs.
|
| 3. | A thoriated tungsten electrode is commonly used, along with a pure argon shielding gas.
|
| 4. | All modern xenon short-arc lamps use a fused quartz envelope with thoriated tungsten electrodes.
|
| 5. | The thoriated-tungsten filament consists of two independent sections mounted on water-cooled supports.
|
| 6. | Another concern for the thoriated magnesium alloys is the low melting point and rapid oxidation of the metal.
|
| 7. | In those used in IMAX projectors, the electrode bodies are made from solid Invar and tipped with thoriated tungsten.
|
| 8. | These valves are bright emitter transmitting valves, and have thoriated tungsten filaments which glow like light bulbs when powered.
|
| 9. | It contains a directly heated thoriated-tungsten filament rated at 16.3 volts at approx . 625 amperes.
|
| 10. | In 1922 the company brought out valves using thoriated tungsten filaments, which needed less battery power to operate than former types.
