Description
Verfahren zurLErzeugung von Schrift- und sonstigen Zeichen mit Hilfe-des$elektrischen Stromes. Die Erfindung betrifft die Erzeugung von Schrift oder anderen Mustern mit Hilfe des elektrischen Stromes. Es ist schon bekannt, unter Anwendung von Oxy derivaten des Benzols, die als photographische Entwickler dienen, und mit Gleichstrom solche Musterungen hervorzurufen. Man hat auch versucht, mittels Anilin oder dessen Salzen ebenfalls mit Gleichstrom dasselbe zu erreichen, was aber nur gelingt, wenn die Druckform die positive Elektrode bildet, was aber die Verwendung von Letternmetall ausschließt: Es wurde nun gefunden, daß man mit Hilfe von Wechselstrom Schriftzeichen auf Papier und Geweben beliebiger Art erzeugen kann, wenn man die mit den Zeichen zu versehenden Materialien mit Salzen aromatischer Amine, wie Anilin, Toluidin oder Mischungen solcher Amine, durchtränkt und die Abscheidung von Anilinschwarz an den zu färbenden Stellen dadurch herbeiführt, daß man das zu färbende Material mit einer Elektrode in Verbindung bringt und durch Berühren mit der Gegenelektrode die Abscheidung hervorruft,- wobei mau diesen Abscheidungen durch Bewegen der Elektrode oder durch Ausgestaltung derselben als Drucktype die gewünschte Gestaltung gibt.Process for the generation of letters and other characters with the help of the $ electric Current. The invention relates to the generation of writing or other patterns Help of the electric current. It is already known to use oxy derivatives of benzene, which serve as photographic developers, and those with direct current To evoke patterns. Attempts have also been made using aniline or its salts the same can also be achieved with direct current, but this only works if the The printing form forms the positive electrode, but what the use of letter metal excludes: It has now been found that one can use alternating current to write characters can be produced on paper and fabric of any kind, if one uses the characters materials to be provided with salts of aromatic amines, such as aniline, toluidine or Mixtures of such amines, soaked and the deposition of aniline black on the to be colored places caused by the fact that the material to be colored with a Brings electrode in connection and by touching the counter electrode the deposition causes, - with these deposits by moving the electrode or by Design of the same as a print type gives the desired design.
Verwendet man ein Material, welches nach vorheriger Tränkung zum Zwecke der Aufbewahrung getrocknet war, so ist vor Anwendung des Verfahrens ein leichtes Befeuchten erforderlich. Dieses kann jedoch, wie wir gefunden haben, dadurch vermieden werden, daß man den zu zeichnenden Materialien neben den Aminsälzen kleine Mengen hygroskopische Substanzen, wie Chlorkalzium, einverleibt.If one uses a material, which after previous impregnation for the purpose after storage has dried, it is easy to use the procedure Moisturizing required. However, as we have found, this can avoid this be that you add small amounts of the materials to be drawn in addition to the amine salts hygroscopic substances such as calcium chloride incorporated.
