  Verfahren zum Entlüften von Gefässen, insbesondere von Glühlampenkolben. 
 EMI1.1

   Im obigen Beispiel war nur von einer Evakuierung des Lampenkolbens die Rede. Es ist klar, dass dieses Verfahren sowohl für luftleere als für gasgefüllte Lampen anwendbar ist. 



   PATENT-ANSPRÜCHE :
1. Verfahren zum Entlüften von Gefässen, insbesondere von Glühlampenkolben, dadurch gekennzeichnet, dass man in das teilweise evakuierte   Gefäss   mindestens ein Metallkarbonyl einführt und das
Gefäss zur Herbeiführung einer Zersetzung des Karbonyls erhitzt, um eine Bindung der Luft und Wasserdampfreste mit dem frei gewordenen Kohlenoxyd herbeizuführen und alsdann die so erhaltenen Gasreste durch die Vakuumpumpe entfernt.

 <Desc / Clms Page number 2>

 



   In the example above, there was only talk of evacuating the lamp bulb. It is clear that this method can be used for both evacuated and gas-filled lamps.



   PATENT CLAIMS:
1. A method for venting vessels, in particular incandescent lamp bulbs, characterized in that at least one metal carbonyl is introduced into the partially evacuated vessel and that
The vessel is heated to bring about a decomposition of the carbonyl in order to bring about a binding of the air and water vapor residues with the released carbon oxide and then the gas residues thus obtained are removed by the vacuum pump.

Claims (1)

2. Verfahren nach Patentanspruch 1, dadurch gekennzeichnet, dass man die Zersetzung des Metallkarbonyls so durchführt, dass das Metall in der Gasatmosphäre suspendiert bleibt und durch die Vakuumpumpe entfernt wird. 2. The method according to claim 1, characterized in that the decomposition of the metal carbonyl is carried out so that the metal remains suspended in the gas atmosphere and is removed by the vacuum pump. 3. Verfahren nach Patentanspruch l, dadurch gekennzeichnet, dass man Nickelkarbonyl verwendet. 3. The method according to claim l, characterized in that nickel carbonyl is used. 4. Verfahren nach Patentanspruch 1, dadurch gekennzeichnet, dass man Molybdän-Karbonyl verwendet. 4. The method according to claim 1, characterized in that molybdenum carbonyl is used. 5. Verfahren nach Patentanspruch 1, dadurch gekennzeichnet, dass man Eisenkarbonyl verwendet. 5. The method according to claim 1, characterized in that iron carbonyl is used. 6. Entlüfteter Glühlampenkolben, erhalten nach dem Verfahren gemäss den Patentansprüchen 1 bis 5, in welchen ein bei der Zersetzung des Metallkarbonyls gebildeter metallischer Spiegel enthalten ist, dadurch gekennzeichnet, dass der metallische Spiegel als Getter zum Binden sich später im Kolben bildender schädlicher Gase dient. 6. Vented incandescent lamp bulb, obtained by the method according to claims 1 to 5, in which a metallic mirror formed during the decomposition of the metal carbonyl is contained, characterized in that the metallic mirror serves as a getter for binding harmful gases later forming in the bulb.
