Description

Verfahren zur Herstellung von Glühfäden für elektrische Glühlampen nach dem
Hilfsmetallverfahren.
EMI1.1
schmelzbares Metall mit einem leicht Flüchtigen Metall zunächst 1. 11 einer duktilen Legierung oder legierungsähnlichen Verbindung vereinigt, hierauf in seine Form gebracht und alsdann von dom Hilfsmetall wieder befreit wird. Das Austreiben des Hilfsmetalls erfolgt nun umso
EMI1.2
Verfahren ist indessen umständlich und der Krfotg unsicher.
Gemäss vorliegender Erfindung wird eine bessere Wirkung dadurch erzielt, dass man den Gesamtquerschnitt des Fadens aus mehreren dünneren Einzelfäden herstellt, deren jeder kreisförtnigen Querschnitt haben kann, und die Fäden durch Verseilen oder dgl. miteinander vereinigt. Der so gewonnene Faden hat dann eine bedeutend grössere Oberfläche als ein kreisrunder Faden von demselben Gesamtquerschnitt haben würde. Vor allen Dingen hat man noch den Vorteil, dass man zur Herstellung des Fadens die in der üblichen Weise gezogenen kreisförmigen Drähte unmittelbar verwenden kann, was für die Massen- fabrikation von Hedeutung ist.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for the production of filaments for electric incandescent lamps according to the
Auxiliary metal process.
EMI1.1
fusible metal is first combined with a readily volatile metal 1. 11 of a ductile alloy or alloy-like compound, then brought into its shape and then freed from the auxiliary metal again. The expulsion of the auxiliary metal takes place all the more
EMI1.2
However, the procedure is cumbersome and the job is unsafe.
According to the present invention, a better effect is achieved in that the overall cross-section of the thread is made from several thinner individual threads, each of which can have a circular cross-section, and the threads are united with one another by stranding or the like. The thread obtained in this way then has a significantly larger surface area than a circular thread with the same overall cross-section would have. Above all, there is the advantage that the circular wires drawn in the usual way can be used directly to produce the thread, which is of importance for mass production.
