Description

Verfahren zum Beschriften von Hartglaskolben, insbesondere Kolben für Elektronenstrahlröhren In der Entladungsröhrentechnik ist es erforderlich, die Kolben der Entladungsgefäße mit einer dauerhaften Beschriftung zu versehen, um die einzelnen Röhren zu kennzeichnen. Bei Verwendung von Weich glaskolben kann eine Kennzeichnung in der Weise bewirkt werden, daß die Kolben zunächst mit Ätztinte beschriftet werden und die Beschriftung durch Erhitzen des Kolbens eingebrannt wird. Für Hartglaskolben sind bisher jedoch keine Verfahren bekanntgeworden, welche eine gut leserliche und auch dauerhafte Beschriftung liefern, so daß sich bereits in -der laufenden Fabrikation von elektrischen Entladungsgefäßen, insbesondere Elektronenstrahlröhren, Unstimmigkeiten ergeben.Method for marking hard glass bulbs, in particular pistons for cathode ray tubes In discharge tube technology it is necessary to have the To provide the flasks of the discharge vessels with permanent lettering to indicate the to identify individual tubes. When using soft glass flasks, a Marking is effected in such a way that the pistons are first coated with etching ink and the lettering is burned in by heating the flask. For hard glass bulbs, however, no methods have been known so far, which one Provide clearly legible and permanent lettering so that the -the ongoing manufacture of electrical discharge vessels, in particular cathode ray tubes, Inconsistencies.

Die Erfindung betrifft ein Verfahren zum Beschriften von Hartglaskolben, insbesondere Kolben von Elektronenstrahlröhren, welches eine einwandfreie Beschriftung liefert. Nach der Erfindung wird die zu beschriftende Stelle des Hartglaskolbens erwärmt und sodann mit Ätztinte beschriftet. Es gelangt also die zur Beschriftung von Weichglaskolben benutzte Ätztinte zur Verwendung. Die zu beschriftende Stelle des Hartglaskolbens kann mittels eines Bunsenbrenners erwärmt und dann mit Ätztinte beschriftet werden.The invention relates to a method for labeling hard glass bulbs, In particular, cathode ray tube pistons, which are perfectly labeled supplies. According to the invention, the point to be inscribed on the hard glass bulb heated and then labeled with etching ink. So it gets to the labeling etching ink used by soft glass bulbs for use. The place to be inscribed The hard glass bulb can be heated with a Bunsen burner and then with etching ink be labeled.
