Abstract: An electric lamp having a lamp envelope transmitting radiation which is sealed in a vacuum-tight manner at least one end by means of a pinch in which at least two current lead-through conductors are sealed. An electric voltage comprising a direct voltage component is present between these conductors during operation of the lamp. A metal scrreming element is placed in the pinch between the two current lead-through conductors. The screening element is connected to the current lead-through conductor which has as an average a negative potential relative to the other current lead-through conductor during operation so that the drawbacks of electrolysis phenomena in the pinch are eliminated.

Abstract: The invention relates to a method of elimination discontinuities in a quartz tube by means of a thermal treatment. According to the invention a plasma burner is used for this treatment in which the quartz tube is passed through an electrical coil being part of this plasma burner, while an inert gas is direct to the quartz tube. As a result the quartz tube is locally heated while mechanical discontinuities can disappear and possible impurities can be removed from the quartz. The part of the quartz tube in which the impurities have accumulated is removed later, if necessary.
