Abstract: A method of producing a low-pressure gas discharge lamp in which a body of a solid material having a thin, structure of filaments permeable to the gas discharge such as glass wool is disposed. Coherence is given to the filaments by compressing them whereafter they are sucked into the lamp envelope. Compressing, knitting together and producing the wire-shaped elements is done in a funnel-shaped space which is connected at its constricted side to the tubular discharge space.

Abstract: A method of manufacturing a scandate dispenser cathode having a matrix at least the top layer of which at the surface consists substantially of tungsten (W) and scandium oxide (Sc.sub.2 O.sub.3) and with emitter material in or below said matrix. If said method comprises the following steps:(a) compressing a porous plug of tungsten powder(b) heating said plug in a non-reactive atmosphere and in contact with scandium to above the melting temperature of scandium,(c) cooling the plug in a hydrogen (H.sub.2) atmosphere(d) pulverizing the plug to fragments(e) heating said fragments to approximately 800.degree. C. and firing them at this temperature for a few to a few tens of minutes in a hydrogen atmosphere and slowly cooling in said hydrogen atmosphere(f) grinding the fragments to scandium hydride-tungsten powder (ScH.sub.2 /W)(g) compressing a matrix or a top layer on a matrix of pure tungsten from said ScH.sub.2 /W powder or from a mixture of this powder with tungsten powder(h) sintering and cooling the said matrix(i) bringing emissive material into the cathode, a scandate dispenser cathode is obtained the recovery of which after ion bombardment occurs better than in cathodes having Sc.sub.2 O.sub.3 grains. The scandium is also distributed more homogeneously in the cathode than in cathodes having Sc.sub.2 O.sub.3 grains.

Abstract: Method of manufacturing a dispenser cathode, in which method tungsten and a scandium-containing material are mechanically alloyed and the product thus formed is pressed into a cathode body. The cathode body is further provided with a barium-containing component. In the mechanical alloying process the tungsten is highly deformed and the scandium-containing material is mixed with the tungsten so as to be very finely distributed therein, so that an improved dispensation of scandium and hence an improved recovery after ion bombardment of the final cathode is attained.
