Die bisher bekannten Verfahren zur Neutralisierung der sich in Faserstoffen bei der Herstellung
und Bearbeitung, z. B. in Fasern und Fäden während des Spinnens und Webens oder in Papier während des Pressens, ansammelnden
Elektrizität bestehen entweder darin, daß man den elektrisierten Stoffen gleichwertige Mengen
ungleichnamiger Elektrizität zuführt oder sie' in ein starkes elektrisches Feld, in dem Spitzenausströmungen
erzeugt werden, setzt. Beiden Verfahren ist der Nachteil eigen, daß zu ihrer Ausübung Hochspannungsgeneratoren, wie z. B.
Influenzmaschinen, Hochspannungstransformatoren, Teslatransformatoren u. dgl., erforderlich
sind, die einen ständigen Energieverbrauch bedingen und an der Arbeitsstelle eine für die mit
der Bearbeitung der Stoffe beschäftigten Personen gefährliche Hochspannung erzeugen.
Diese Nachteile werden gemäß der Erfindung dadurch beseitigt, daß der elektrisierte Stoff der
Einwirkung eines durch radioaktive Substanzen künstlich leitend gemachten Mediums, vorzugsweise
einer solchen Atmosphäre von Gas (Luft), ausgesetzt wird, so daß die auf ihm befindlichen
elektrischen Ladungen durch die ionisierte Atmosphäre nach den in der Umgebung befindlichen
geerdeten Körpern, d. h. zur Erde abgeleitet werden. Um eine raschere Ableitung der Ladungen nach der Erde hin zu erzielen,
ist es zweckmäßig, in der Nähe des zu neutralisierenden Stoffes eine ihn zum Teil oder im
ganzen umgebende, geerdete Elektrode anzuordnen, wobei es sich empfiehlt, nur die zwischen
dem Isolierstoff und der geerdeten Elektrode befindliche Atmosphäre zu ionisieren.The previously known methods for neutralizing the fibers in the production and processing, z. The accumulating electricity, e.g. in fibers and threads during spinning and weaving or in paper during pressing, consists either in supplying the electrified substances with equivalent amounts of dissimilar electricity or in placing them in a strong electric field in which peak vents are produced . Both methods have the disadvantage that high-voltage generators such. B. Influence machines, high-voltage transformers, Tesla transformers and the like, are required, which require constant energy consumption and generate a dangerous high voltage for the people involved in the processing of the substances at the workplace.
These disadvantages are eliminated according to the invention in that the electrified substance is exposed to the action of a medium made artificially conductive by radioactive substances, preferably such an atmosphere of gas (air), so that the electrical charges on it are transferred through the ionized atmosphere the earthed bodies in the vicinity, ie be diverted to earth. In order to achieve a faster discharge of the charges to the earth, it is advisable to arrange a partially or completely surrounding, earthed electrode in the vicinity of the substance to be neutralized, whereby it is advisable to use only the one between the insulating material and the earthed electrode To ionize the atmosphere located in the electrode.
Dieses Verfahren kann z. B. in der Weise ausgeführt werden, daß man unterhalb des zu
neutralisierenden Stoffes eine geerdete Elektrode (Platte, Drahtnetz) anordnet, auf welcher,
und zwar auf der dem Faserstoff zugekehrten Seite, radioaktive Stoffe verteilt sind. Man
kann auch den zu neutralisierenden Stoff mit einer kasten- oder rohrförmigen geerdeten
Elektrode umgeben, die zweckmäßig auf ihrer inneren Oberfläche in Form einer Belegung
radioaktive Stoffe enthält. Die kasten- oder rohrförmigen Elektroden können auch aus
durchbrochenem Blech oder einem Drahtnetz hergestellt sein und die radioaktiven Stoffe
außerhalb dieser angeordnet werden. Diese Anordnung bietet den Vorteil einer bequemen
Erneuerung der radioaktiven Stoffe.
• Als den zu neutralisierenden Stoff umgebende Elektroden können auch vorhandene Konstruktionsteile
der Arbeitsmaschine verwendet werden.This method can e.g. B. be carried out in such a way that a grounded electrode (plate, wire mesh) is arranged below the substance to be neutralized, on which, on the side facing the fiber, radioactive substances are distributed. The substance to be neutralized can also be surrounded by a box-shaped or tubular grounded electrode, which expediently contains radioactive substances on its inner surface in the form of a coating. The box-shaped or tubular electrodes can also be made of perforated sheet metal or a wire mesh and the radioactive substances can be arranged outside these. This arrangement offers the advantage of a convenient replacement of the radioactive substances.
• Existing structural parts of the working machine can also be used as electrodes surrounding the substance to be neutralized.
In der Zeichnung ist ein Ausführungsbeispiel für die Neutralisierung eines gesponnenen Fadens dargestellt. H1 ist eine Spindel, von welcher der Faden F abgewickelt wird, um durch Streckwalzen W hindurchgeleitet und durch eine Führung C auf eine Spindel H2 aufgewickelt zu werden. Nachdem der Faden das letzte Streckwalzenpaar passiert hat, wird er zwecks Neutralisierung der Elektrizität, die sich auf ihm infolge der Berührung mit den Streck-In the drawing, an embodiment for the neutralization of a spun thread is shown. H 1 is a spindle from which the thread F is unwound to be passed through drawing rollers W and wound onto a spindle H 2 through a guide C. After the thread has passed the last pair of drafting rollers, it is used to neutralize the electricity that is on it as a result of contact with the drafting rollers.
