Abstract: A high intensity lamp comprising an arc tube containing metal vapor such as sodium and mercury mounted within an evacuated outer jacket based at one end. The possibility exists of a destructive power arc forming within the vacuum jacket should there occur a leak of air into the jacket or should the arc tube fail resulting in a partial pressure of gas in the outer bulb. A self-shorting arcing fuse is provided within the jacket to extinguish such arc safely and end the life of the lamp. A second self-shorting arcing fuse may also be built into the base as an additional safety measure.

Abstract: In horizontally operated high pressure sodium vapor lamps using alumina ceramic envelopes, spotting and blackening of the envelope has been traced to loose emission material released from the electrodes. Loss of emission material from a double layer wound tungsten electrode is prevented by wrapping a foil of refractory metal such as tungsten or molybdenum around the inner coil after the emission material has been applied, and then winding or screwing the outer coil over the foil. The outer coil holds the foil in place and the foil in turn holds the emission material in place.

Abstract: An electric discharge lamp comprising a tubular lighttransmitting envelope of alumina ceramic closed at each end by refractory metal end caps. The envelope contains a discharge sustaining filling and electrodes supported by the end caps. At least one end cap is a thin-walled metal thimble having a skirt portion sealed to the end of the tube and a central blind teat in which the electrode shank is seized. The need for critical welding or brazing to the end cap is thereby avoided.
Abstract translation: 一种放电灯，包括在每端由难熔金属端盖封闭的氧化铝陶瓷的管状透光外壳。 信封包含放电维持填充物和由端盖支撑的电极。 至少一个端盖是具有密封到管的端部的裙部的薄壁金属套管和其中抓住电极柄的中心盲乳头。 从而避免了对端盖进行临界焊接或钎焊的需要。
