 EMI2.1 
 statt der   Platinseele   einen, wie dort   angeführt, dünnen Draht aus   einem hitzebeständigen Metalle der oben angeführten Gruppen mit Osmium überziehen und durch den elektrischen 
 EMI2.2 
 seiner Verbindungen überziehen und schliesslich im Vakuum, einem reduzierenden oder indifferenten Gase durch den elektrischen Strom erhitzen.

 EMI2.1
 Instead of the platinum soul, as stated there, coat a thin wire made of a heat-resistant metal of the above-mentioned groups with osmium and through the electrical
 EMI2.2
 its connections and finally heated in a vacuum, a reducing or inert gas by the electric current.

Claims (1)

PATENT-ANSPRÜCHE : 1, Ausführungsform der durch Anspruch 2 des Stamm-Patentes Nr. 9061 und Anspruch 2 des Zusatz-Patentes Nr. 9693 geschützten Verfahren, dadurch gekennzeichnet, dass der Osmiumpaste verhältnismässig leicht reduzierbaro Oxyde eines oder mehrerer dar schwor schmelzbaren Metalle (Chrom, Molybdän, Wolfram, Uran bezw. Kobalt, Nickel) zugesetzt werden und der Faden sodann in bekannter Weise im Vakuum, in einem indifferenten oder reduzierenden Gase geglüht wird. PATENT CLAIMS: 1, embodiment of the process protected by claim 2 of parent patent no. 9061 and claim 2 of additional patent no. 9693, characterized in that the osmium paste is relatively easily reducible oxides of one or more fusible metals (chromium, molybdenum, tungsten , Uranium or cobalt, nickel) are added and the thread is then annealed in a known manner in a vacuum, in an inert or reducing gas. 2. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass zwecks Verhinderung von Karbidbildung die in der Osmiumpaste enthaltene Menge Kohlenstoff in keinem Falle grösser, sondern eher kleiner gewählt wird, als zur Reduktion des beigemengten Oxydes notwendig ist. 2. Embodiment of the method according to claim 1, characterized in that, for the purpose of preventing carbide formation, the amount of carbon contained in the osmium paste is in no case greater, but rather smaller than is necessary for reducing the added oxide. 3. Ausführungsform des Verfahrens nach Anspruch 3 des Stamm-Patentes Nr. 9061, dadurch gekennzeichnet, dass anstatt der Platinsodo ein Draht aus irgendeinen ! der schwer schmelzbaren Metalle (Chrom, Molybdän, Wolfram, Uran bezw. Kobalt, Nickp !) oder einer Legierung solcher Metalle, oder ein aus diesen Metallen nach Art dos Osmiumfadens des Stamm-Patentes hergestellter Metallfaden, mit Osmium oder mit Osmium und Metallen der Platingruppo oder mit Verbindungen dieser Metalle überzogen und in einer geeigneten Gasatmosphäre oder im Vakuum geglüht wird. 3. Embodiment of the method according to claim 3 of the parent patent no. 9061, characterized in that instead of the Platinsodo a wire from any! the difficult-to-melt metals (chromium, molybdenum, tungsten, uranium or cobalt, nick!) or an alloy of such metals, or a metal thread made from these metals in the manner of the osmium thread of the Stamm patent, with osmium or with osmium and metals of the platinum group or coated with compounds of these metals and calcined in a suitable gas atmosphere or in a vacuum.
