Description

Einbringstoff für elektrische Glühlampen und ähnliche Glasgefäße. Um die Lebensdauer von elektrischen Glühlampen und ähnlichen Glasgefäßen zu verbessern, ist es üblich, in sie Stoffe einzubringen, die die Schwärzung der Glocke verhindern und insbesondere Feuchtigkeitsreste bzw. entstehenden Wasserdampf binden.Feed material for electric light bulbs and similar glass vessels. To improve the service life of electric light bulbs and similar glass vessels, it is customary to incorporate substances into them that prevent the bell from blackening and in particular bind moisture residues or resulting water vapor.

Die Erfindung beruht in der Erkenntnis, daß eine Verbindung von Phosphorsäureanhydrid (Phosphorpentoxyd) mit dem Oxyde eines beliebigen anderen Metalloides als Einbringstoff mit gutem Erfolge verwendbar ist. Günstige Ergebnisse lassen sich durch Verwendung von Borphosphat (BPO,) erreichen. Ähnlich wirkt das analoge Silicylphosphat (5102. P205).The invention is based on the knowledge that a compound of phosphoric anhydride (Phosphorus pentoxide) with the oxide of any other metalloid as a feed material can be used with good results. Favorable results can be obtained by using of boron phosphate (BPO,). The analogous silicyl phosphate (5102. P205).

Ob die gute Wirkung derartiger, bei gewöhnlicher Temperatur nicht wasseranziehend wirkender Einbringstoffe auf die erst bei, Wärmeeinwirkung eintretende Zersetzung oder schon allein auf die bei der Verdampfung eintretende feine Verteilung oder auch auf sonst irgendeinen Umstand zurückzuführen ist, mag dahingestellt bleiben.Whether the good effect of such, not at ordinary temperature water-attracting substances to be added to those that only occur when exposed to heat Decomposition or simply due to the fine distribution that occurs during evaporation or can be traced back to any other circumstance, may remain open.

Die neuen Einbringstaffe können in bekannter Weise in das Glasgefäß von Vakuumlampen oder auch gasgefüllten Glühlampen eingebracht werden. Vorteilhaft wird beispielsweise Borphosphat mit Wasser oder Alkohol zu- einer Suspension angerührt und dann, wie bei anderen Einbringstoffen bekannt, auf die bespannten Leuchtkörpertraggestelle gesprüht. Es kann aber selbstverständlich auch der Leuchtkörper oder das bespannte Leuchtkörpertraggestell in eine solche Suspension eingetaucht werden. Günstig ist die Wirkung insbesondere dann, wenn nicht nur der Leuchtkörper, sondern auch solche ihm: benachbarten Teile der Lampe mit Borphosphat versehen werden, die beim Betriebe der Lampe eine weniger hohe Temperatur als der Leuchtkörper annehmen, so daß die Zersetzung bzw. Verdampfung allmählich erfoilgt. Neben den neuen Einbringstoffen können in die Lampe auch noch andere, an sich bekannte Einbringstoffe eingebracht werden, etwa Phosphor, Halogensalze (wie Kryolith) oder Sauerstoff enthaltende Einbringstoffe.The new bringing-in staff can be placed in the glass vessel in a known manner be introduced by vacuum lamps or gas-filled incandescent lamps. Advantageous For example, boron phosphate is mixed with water or alcohol to form a suspension and then, as is known with other materials to be brought in, onto the covered filament support frames sprayed. Of course, it can also be the lamp or the strung Luminous body support frame are immersed in such a suspension. Is cheap the effect especially when not only the luminous element, but also such him: neighboring parts of the lamp are provided with boron phosphate, which when operating the lamp assume a less high temperature than the filament, so that the Decomposition or evaporation takes place gradually. In addition to the new input materials can also be introduced into the lamp other, per se known introduction materials such as phosphorus, halogen salts (such as cryolite) or oxygen-containing feed materials.
