Description
Telegramm-Empfangsstreifen, von dem die aufgetragenen Zeichen zwecks wiederholter Benutzung des Streifens leicht entfernt werden können. Nach vorliegender Erfindung wird an Stelle eines Papierstreifens ein vornehmlich aus ' Magnesium, Aluminium oder deren Legierungen hergestelltes dünnes Band zur Aufnahme von telegraphischen Zeichen verwendet.Telegram receiving strip from which the applied characters can easily be removed for repeated use of the strip. According to the present invention, a strip of paper is mainly made of a 'magnesium, aluminum or their alloys thin ribbon used for recording telegraphic character in place.
Diese Metalle haben die Eigenschaft, selbst nach sorgfältigster chemischer Reinigung des Metalls sich selbsttätig sofort mit einer feinen Oxvdschicht zu überziehen. Auf dieser feinen Oxvdschicht haften Schriftzeichen sehr leicht undy lassen sich auch leicht wieder entfernen, so daß das Band immer wieder verwendbar ist.These metals have the property, even after the most careful chemical Cleaning of the metal to automatically coat itself immediately with a fine layer of oxide. Characters adhere very easily to this fine oxide layer also easy to remove again, so that the tape can be used again and again.
Der Vorteil des Magnesiums liegt insbesondere darin, daß die Oxvdschicht nicht besonders, wie etwa bei einem anderen Metall, erzeugt werden muß und sich selbsttätig und kostenlos hervorruft. Außerdem lassen sich beide Seiten des Bandes gleich gut zur Aufnahme der Zeichen verwenden.The particular advantage of magnesium is that the oxide layer does not have to be generated particularly, as is the case with another metal, for example automatically and free of charge. You can also use both sides of the tape use equally well to pick up the characters.
