Description

Träger für den Elektrolyten und den Indikator bei elektrisch registrierenden Meßgeräten Bekanntlich kann man die Polarität spannungsführender Enden mit Hilfe eines mit Salz und Indikator imprägnierten und nassen Papiers feststellen, wobei an einem oder an beiden Polen der Indikator auf dem Papier seine Farbe ändert. Man hat auch schon vorgeschlagen, derartiges Registrierpapier zur Anzeige von Gleich- und Wechselstrom, zur Freduenzmessung sowie zur Registrierung von auf elektrischem Wege gegebenen Zeichen zu verwenden.Carrier for the electrolyte and the indicator for electrically registering Measuring instruments As is well known, one can determine the polarity of live ends with the help of a wet paper impregnated with salt and indicator, where at one or both poles the indicator on the paper changes color. Man has already proposed to use such a recording paper for the display of equal and alternating current, for measuring freshness and for registering on electrical Ways to use given signs.

Man hat weiter vorgeschlagen, den aus Papier bestehenden Registrierstreifen mit einem Elektrolyten, einem Indikator und hygroskopischen Zusätzen zu imprägnieren. Solches Registriermaterial kann ohne vorhergehende Anfeuchtung verwendet werden; es besitzt Jedoch noch einen erheblichen Nachteil, da seine Festigkeit recht gering ist und dies z. B. bei Verwendung des Registriermaterials für schnell laufende Telegraphiestreifen leicht zu Störungen Anlaß geben kann.It has also been proposed that the recording strip made of paper to impregnate with an electrolyte, an indicator and hygroscopic additives. Such recording material can be used without prior moistening; However, it still has a significant disadvantage that its strength is quite low is and this z. B. when using the recording material for fast running telegraph strips can easily give rise to disturbances.

Es ist nun gefunden worden, daß man durch Imprägnieren von Folien aus regenerierter Cellulose mit einem Elektrolyten und einem Indikator einen Werkstoff erhält, der eine hervorragende Eignung als Stromanzeigematerial besitzt. Das neue Material kann in trockenem Zustande verwendet werden, ohne daß ihm hygroskopische Stoffe einverleibt werden, da es infolge seines Quellwassergehaltes auch in lufttrockenem Zustand die Farbreaktion oder sonstigen Veränderungen des Indikators sehr deutlich zeigt. Der besondere Vorteil des neuen Materials gegenüber den bekannten aus Papier bestehenden Registriersto -f-fen besteht in seiner erheblich größeren Festigkeit, durch die das Material eine hohe Überlegenheit für Telegraphierzwecke besitzt.It has now been found that by impregnating foils from regenerated cellulose with an electrolyte and an indicator a material obtained, which has excellent suitability as a current display material. The new Material can be used in a dry state without being hygroscopic Substances are incorporated, as it is also air-dry due to its spring water content The color reaction or other changes in the indicator are very clear shows. The particular advantage of the new material over the familiar ones made of paper existing registration substances consists in its considerably greater strength, which gives the material a high degree of superiority for telegraphing purposes.

Als Indikatoren kommen für das neue Verfahren die üblichen Substanzen, wie z. B. Phenolphtalein, in Betracht, ferner auch Diazoverbindungen allein oder in Mischung mit Azokomponenten sowie* L,euko@es.ter von Küpenfarbstoffen u. dgl. Bei Verwendung von Diazoverbindungen oder von Leukoestern ist es empfehlenswert, solche Verbindungen zu benutzen, die relativ lichtunempfindlich sind. Gegebenenfalls kann man hierbei auch noch geeignete Stoffe, wie z. B. Farbstoffe, hinzusetzen, die die Lichtempfindlichkeit der genannten Stoffe herabsetzen. Als Elektrolyt verwendet man die verschiedensten Salze.The usual substances, such as. B. phenolphthalein, also diazo compounds alone or in a mixture with azo components as well as * L, euko @ es.ter of vat dyes and the like. When using diazo compounds or leuco esters, it is advisable to use compounds that are relatively insensitive to light are. If necessary, you can also use suitable substances, such as. B. dyes, add that reduce the photosensitivity of the substances mentioned. A wide variety of salts are used as the electrolyte.

Man kann die neuen imprägnierten Folien durch Zusatz von Weißpigment zur Viscose undurchsichtig und weiß machen, was den Vorteil. 'hat, daß die Farbreaktionen dann deutlicher werden. Für die Üntersuchung höherer Spannungen kaschiert man zweckmäßig die Folien teilweise mit elektrisch nichtleitenden Folien züm Schutz gegen Schläge.You can make the new impregnated foils by adding white pigment to make viscose opaque and white what the advantage. 'has that color reactions then become clearer. For the investigation of higher voltages the foils are expediently partially laminated with electrically non-conductive foils for protection against blows.

Das neue Material wird hauptsächlich in Streifenform für - Telegraphierzwecke verwendet. Man läßt hierbei einen imprägnierten Streifen z. B. zwischen zwei aufeinanderrollenden Kontakten hindurchlaufen. Die ankommenden Stromstöße werden dabei in ar sich bekannter Weise durch Veränderungen des Indikators sichtbar gemacht.The new material is mainly in strip form for telegraphing purposes used. One leaves here an impregnated strip z. B. between two rolling one on top of the other Run through contacts. The incoming power surges become more well-known Way made visible by changing the indicator.
