Verfahren zur Herstellung von Haltern für Metallglühfäden elektrischer Glühlampen.

die auf galvanischem Wege vollständig mit Chrom überzogenen Halter ausgeglüht werden.
Halter für Metallglühfäden, die aus leicht schmelzbaren Metallen bestehen und mit schwer schmelzbaren Metallen überzogen sind, sind an und für sich bekannt, doch entsprechen dieselben dem Zwecke nicht, namentlich, wenn es sich ! um sogenannte federnde Halter für gespannte Glühfäden handelt, welche Halter aus dünnem Blech oder Draht hergestellt sind.
Überzieht man Bänder oder Drähte aus Metallen mit Chrom, so findet man, dass sich dieselben nicht in die Form bringen lassen, die beispielsweise für gespannte Metallgliih- fäden erforderlich ist, da sie zu stark federnd und bei einer scharfen Biegung leicht brechen.
Infolge der zu starken Federung reissen ganz dünne gespannte Glühfäden im Gebrauche sehr leicht, wenn sie mit derartigen Halterungen gehaltert werden.
Anmelder hat. nun gefunden, dass diese Eigenschaft der Drähte, Bänder und dorgl.

gerade eine Elastizität, wie sie xum Spannen der Gtühfäden erforderlich ist. In Wirklichlieit liegt daher in dem mit Chrom überzogenen ausgeglühten Metall ein ganz anderer Körper vor, der weder die physikalischen Eigenschaften des Grundmetalles, noch die des Chroms besitzt. Wir haben es vielmehr mit einem Körper zu tun, bei dem die günstigen Eigenschaften beider Metalle zur Geltung kommen ; die Biegsamkeit des Grundmetalles und die Schwerschmelzbarkeit des Chromüberzuges. Es hat den Anschein, als ob beim GlÜhen eine

Process for the production of holders for metal filaments of electric incandescent lamps.
EMI1.1
the holders, which are completely coated with chrome, are annealed by electroplating.
Holders for metal filaments, which consist of easily fusible metals and are coated with difficult to fusible metals, are known per se, but they do not correspond to the purpose, especially when they are! are so-called resilient holders for tensioned filaments, which holders are made of thin sheet metal or wire.
If strips or wires made of metals are coated with chromium, one finds that they cannot be brought into the shape required, for example, for tensioned metal filaments, since they are too resilient and break easily when bent sharply.
As a result of the excessive springiness, very thin, tensioned filaments tear very easily in use if they are held with such holders.
Applicant has. now found that this property of wires, ribbons and the like.

just the kind of elasticity required to tension the yarn. In reality, therefore, in the annealed metal coated with chrome there is an entirely different body, which has neither the physical properties of the base metal nor those of chrome. Rather, we are dealing with a body in which the favorable properties of both metals come into their own; the flexibility of the base metal and the low fusibility of the chrome coating. It appears that when glowing there is a
EMI1.3
Properties could be ascribed to this circumstance.
