EMI2.1 Nr. 32521, darin bestehend, dass dem aus Wolframdioxyd und einer ammoniakalischen Kaseinlösung bestehenden Ausgangsmaterial bis zu gleichen Gewichtsteilen pulverförmiges Wolframmetall zugesetzt wird, wodurch den daraus hergestellten Fäden, ohne sie überhitzen zn müssen, eine grössere Festigkeit verliehen wird. EMI2.1 No. 32521, which consists in adding up to equal parts by weight of powdered tungsten metal to the starting material consisting of tungsten dioxide and an ammoniacal casein solution, whereby the threads made from it are given greater strength without having to overheat them.
