Verfahren zur Herstellung eines Tauchbades für Glühkörper.Process for the production of an immersion bath for incandescent bodies.
Zum Hartmachen der Glühkörper zum Zwecke eines bequemen Transports werden die imprägnierten Glühkörper durch Eintauchen in eine Lösung von Kollodiumwolle mit einem die Strumpfmaschen vollständig deckenden Nitrozelluloseüberzug versehen, welcher die Transportfähigkeit der Glühkörper gewährleistet. Der Nitrozelluloseüberzug hat nun den Nachteil, daß er beim TrocknenTo make the incandescent bodies hard for the purpose of convenient transportation the impregnated incandescent body by immersing it in a solution of collodion wool provided a nitrocellulose coating that completely covers the hosiery mesh ensures that the incandescent bodies can be transported. The nitrocellulose coating has now the disadvantage that he was drying
ίο eine Schrumpfung des Glühkörpers herbeiführt, wodurch der Glühkörper unbrauchbar wird. Zur Behebung dieses Übelstandes wird dem Tauchbad neben anderen Stoffen Rizinusöl und Kampfer zugesetzt. Die vorliegende Erfindung bezweckt, den Kampfer im Tauchbade durch eine weniger kostbare Substanz zu ersetzen.ίο causes the incandescent body to shrink, whereby the incandescent body becomes unusable. To remedy this problem, castor oil is added to the immersion bath, along with other substances and camphor added. The present invention aims to improve the camphor in the Replacing immersion baths with a less valuable substance.
Man hat bereits gefunden, daß zusammengesetzte Äther (Ester) und Aldehyde hierfür gut geeignet sind. Es hat sich noch gezeigt, daß außer diesen beiden Gruppen von Ersatzstoffen auch die Nitroverbindungen der aromatischen Körper die Eigenschaft haben, die Schrumpfung der mit einem deckenden Nitrozelluloseüberzug versehenen Glühkörper zu verhindern, so daß die Nitroverbindungen als ein billiger Ersatz für den teuren Kampfer dienen können. Das Verhalten der einzelnen Nitroverbindungen als Kampferersatzmittel ist nicht gleichmäßig, insofern als beispielsweise mit Nitrobenzol und Nitrotoluol vorzügliche Resultate erzielt wurden, wogegen die Ergebnisse mit Nitroanisol und Nitrophenetol weniger gut, obwohl noch immer brauchbar waren. Auch andere Nitroverbindüngen zeigten ein ähnliches Verhalten, so daß zweifellos unter den vielen Nitroverbindungen noch zahlreiche Nitrokörper existieren werden, die vorzüglich als Ersatzstoffe für Kampfer dienen können, weshalb nicht nur die genannten Nitroverbindungen der aromatischen Stoffe, sondern aromatische Nitroverbindungen überhaupt Gegenstand des Patents sein sollen.It has already been found that composite ethers (esters) and aldehydes can be used for this are well suited. It has also been shown that in addition to these two groups of Substitutes also the nitro compounds of the aromatic bodies have the property the shrinkage of the incandescent bodies provided with an opaque nitrocellulose coating to prevent the nitro compounds as a cheap substitute for the expensive camphor can serve. The behavior of the individual nitro compounds as a camphor substitute is not uniform in that, for example, with nitrobenzene and nitrotoluene excellent results were achieved, whereas the results with nitroanisole and nitrophenetol less good, although still usable. Other nitro compounds too showed similar behavior, so that undoubtedly among the many nitro compounds Numerous nitro bodies will still exist, which are excellent substitutes for Camphor can serve, which is why not only the nitro compounds mentioned are aromatic Substances, but aromatic nitro compounds should be the subject of the patent.
