Description

Stromeinführungsdraht zur luftdichten Einschmelzung in Glas, insbesondere für elektrische Glühlampen u. dgl.Current lead-in wire for airtight sealing in glass, in particular for electric light bulbs and the like.

Zusatz zum Patent 396217. Im Hauptpatent 396a17 ist ein Stromeinführungsdraht zur luftdichten Einschmelzung in Glas, insbesondere für elektrische Glühlampen u. dgl., geschützt, bei welchem an Stelle der Längsrillen schrauteirlinienartige Rillen getreten sind. Zur Herstellung der so ausgeführten Stromeinführungsdrähte dienen nach (lein Hauptpatente folgende bekannten Verfahren: Anwendung von rotierendem Zieh-::teiiie oller Schleifwerkzeuge; Rotieren des Drahtes selbst während des Ziehens.Addition to patent 396217. In main patent 396a17 there is a current lead-in wire for airtight sealing in glass, especially for electric light bulbs and the like. Like., Protected, in which instead of the longitudinal grooves, ridges-like grooves have stepped. Serve to produce the power lead-in wires executed in this way according to (lein main patents the following known processes: application of rotating Drawing - :: part of all grinding tools; Rotating the wire itself while pulling.

Ein weiteres Verfahren zur Herstellung solcher mit schraubenli wienartigen Rillen versehenen Stromeinführungsdrähte besteht nun darin. (laß ein auf üblicher Weise mit ruhendem Ziehsteine bzw. bei nicht rotierendem Drahte gezogener Draht nachher um seine eigene Achse verdreht, (1. h. einer Torsion unterworfen wird. Dieses Verfahren hat den Vorteil, daß zur Herstellung der schraubenlinienfni-inige -Rillen aufweisenden Drähte keine besondere Zieheinrichtung nötig ist.Another method of making those with schraubli wien-like Grooved power entry wires is now in it. (let in on the usual Way with stationary drawing dies or wire drawn with non-rotating wire afterwards twisted around its own axis, (1. i. is subjected to a torsion. This The method has the advantage that for the production of the helical grooves having wires no special pulling device is necessary.

Eine weitere Ausführungsart der im zweiten Anspruch des Hauptpatentes geschützten Drähte besteht darin, daß an die flachgedrückte, in dasGlas einztischmelzendeStelle desDrahtes Leiter ohne schraubenlinienartig oder quer verlaufende Rillen angesetzt sind. - Diese finit Abflachung versehenen Einführungsdrähte k<innen ferner zwecks weiterer Erhöhung der Betriebssicherheit sowie zur Schonung (leg drahtförmigen Leiters beim Flachdrü(Ken bzw. .-Xuswalzen ein oder mehrfach abgestuft sein. Es wird z. B. der Draht zweimal flachgedrückt: (las erntemal auf einer - längeren Strecke auf einem mittleren Durchmesser, dann auf einer kürzeren Strecke auf den kleinsten Durchmesser.Another embodiment of the second claim of the main patent protected wires consists in that at the flattened point that melts into the glass of the wire conductor without helical or transverse grooves are. - This finitely flattened lead-in wires k <inside also for the purpose further increase of operational safety as well as protection (leg wire-shaped conductor be stepped one or more times in Flachdrü (Ken or.-Xuswalzen. B. the wire flattened twice: (read once on a - longer distance a medium diameter, then a shorter distance to the smallest diameter.

Beispiel : Ein Kupferdraht von 0,351-11111 Durchmesser wird erst auf o,lo, dann auf Dicke von o,od. inni abgeflacht; die endgültige Form .des Einführtingsdrahtes ver-1<ittft dann wie folgt: Zvlindrischer Draht von Durchmesser 0,35 min, .Example: A copper wire with a diameter of 0.351-11111 is first opened o, lo, then to thickness of o, od. inni flattened; the final shape of the introducer wire Then it is used as follows: Cylindrical wire with a diameter of 0.35 min.

Abflachung über eine Länge von 1,5 mm auf eine Dicke voll o,1 o mm, Abflachung über eine Länge von 3,5 iniri auf eine Dicke von o,o- mm, Abflachung über eine Länge von 1,5 nun auf eine Dicke von o,ro mm, dann wieder zylindrischer Draht von Durchmesser 0,35 mm.Flattening over a length of 1.5 mm full o a thickness 1 mm o, flattening over a length of 3, 5 iniri to a thickness of o, o- mm, flattening over a length of 1.5 now has a thickness o, ro mm, then again cylindrical wire with a diameter of 0.35 mm.
