Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Patentschrift 220051 beschreibt eine Maschine, welche das Spinnen viskoser Flüssigkeiten unter Anwendung bewegter Flüssigkeiten zur Förderung des Fadens gestattet.
Luftblasen in der zur Fällung der Kupferoxydammoniakcelluloselösung dienenden Flüssigkeit sind außerordentlich störend bei der Fadenbildung. Solche Luftblasen entwickeln sich aber unausgesetzt aus der unter verminminderten! Druck stehenden Fällflüssigkeit, da stets Luft darin enthalten ist.The patent specification 220051 describes a machine which allows the spinning of viscous liquids using agitated liquids to convey the thread.
Air bubbles in the liquid used to precipitate the copper oxide ammonia cellulose solution are extremely disruptive in the formation of threads. Such air bubbles develop continuously from the under reduced! Precipitation liquid under pressure, as it always contains air.

Diesen Störungen sucht die bekannte Vorrichtung durch einen besonderen doppelten Abdichtungsring abzuhelfen, der den Abzug der in der Umlauf flüssigkeit enthaltenen Luftblasen ermöglicht. Der Zweck wird indessen nur unvollkommen erreicht, da sich eben stets neue Blasen bilden und in mannigfacher Weise die Kontinuität der Fädchen stören.The known device searches for these disturbances by means of a special double one Sealing ring to remedy the withdrawal of the air bubbles contained in the circulating fluid enables. However, the purpose is only imperfectly achieved because it is always new bubbles form and in many ways disrupt the continuity of the threads.

Es hat sich nun gezeigt, daß diese lästigen Störungen in einfachster Weise vermieden werden können, wenn man von vornherein eine Fällflüssigkeit verwendet, die keine gelösten Gase enthält, also auch keine Blasen entwickeln kann.It has now been shown that these annoying disturbances can be avoided in the simplest possible way can, if one uses a precipitating liquid from the start that does not have a dissolved one Contains gases, so it cannot develop bubbles.

Im Falle der Verwendung von reinem Wasser z. B. entzieht man ihm vor der Verwendung alle gelöste Luft durch Evakuieren, das man durch Erwärmen noch unterstützen kann.In the case of using pure water e.g. B. is withdrawn from it before use all dissolved air by evacuation, which can be supported by heating.

Bei Verwendung solcher Flüssigkeiten, die frei von gelösten Gasen sind, geht das Spinnen äußerst gleichmäßig und ohne jegliches Abreißen vor sich.When using liquids that are free of dissolved gases, the spinning works extremely evenly and without any tearing in front of you.
