Description

Die Erfindung betrifft Durchschreibmaterial zum Vervielfältigen von Schrift- und ähnlichen Zeichen.The invention relates to copy material for copying written and similar characters.

Das Durchschreibmaterial besteht aus einem Grundbogen mit einem eine Dispersion feiner Teilchen eines magnetisierbaren Materials enthaltenden Überzug, der bei auf die Oberseite des Bogens angewandter Druckkraft auf eine darunterliegende Fläche übertragen wird.The copy material consists of a base sheet with a finer dispersion Coating containing particles of a magnetizable material which, when applied to the top of the Arch's applied compressive force is transferred to an underlying surface.

Ein solcher Bogen ist nützlich für das Übertragen magnetisierbarer oder magnetisierter Stellen auf Aufzeichnungsmaterial, wobei derartige Stellen durch ihre Lage oder Anzahl ausgewählte Angaben auf dem Aufzeichnungsmaterial darstellen. Such an arc is useful for transferring magnetizable or magnetized Positions on recording material, such positions being selected by their position or number Present information on the recording material.

Der erfindungsgemäße Übertragungsbogen wird ähnlich wie Kohlepapier verwendet, d. h. er wird auf das Aufzeichnungsmaterial, ζ. Β. Papier, mit der beschichteten Seite nach unten gelegt, und dort, wo Markierungen auf dem Papier zurückbleiben sollen, wird ein Teil des Überzugs infolge der angewandten Druckkraft auf das Papier übertragen. Das übertragene Material des Überzugs hat in sich die angemessene Menge des dispergierten, magnetisierbaren Stoffs, der in magnetisiertem oder entmagnetisiertem Zustand sein kann. Wenn die Teilchen in dem Übertragungsbogen magnetisiert sind, bleiben die bei Druckkraftanwendung z. B. durch einen Griffel oder eine Type auf das Papier übertragenen Teilchen magnetisiert, was die Orientierung der Teilchen nicht so sehr beeinflußt, daß dadurch die totale magnetische Wirkung beeinträchtigt würde. Um die besten Ergebnisse zuThe transfer sheet of the present invention is used in a manner similar to carbon paper; H. he will on the recording material, ζ. Β. Paper, with the coated side down, and there, where marks are to be left on the paper becomes part of the coating as a result of the applied Transferring pressure to the paper. The transferred material of the coating has in the appropriate amount of the dispersed, magnetizable material that is in the magnetized or demagnetized state. When the particles are magnetized in the transfer sheet are, remain the z. B. by a stylus or a type on the Paper-transferred particles are magnetized, which does not affect the orientation of the particles so much, that this would impair the total magnetic effect. To get the best results too

erzielen,, müssen die Pole aller magnetisierten Teilchen beim Magnetisieren des Bogens in der gleichen Richtung, parallel zur Bogenfläche und nicht senkrecht zu dieser, orientiert sein. Dies kann leicht erzielt werden, indem man einen Magneten . quer über die Vorder- oder Rückfläche des Bogens zieht«achieve, must have the poles of all magnetized Particles when magnetizing the arc in the same direction, parallel to the arc surface and not be oriented perpendicular to this. This can easily be achieved by using a magnet . pulls across the front or back surface of the bow "

Vorzugsweise- wird Papier als Grundlage, auf welche der Überzug aufgetragen wird, verwendet, obwohl auch andere dünne Schichten, die als Gewebe öder Film ausgebildet sind, verwendet werden können. Beispielsweise ist fein gewebtes Tuch oder Celluloseacetatfllm an Stelle von Papier verwendbar.Preferably - paper is used as the base on which the coating is applied, although other thin layers formed as a fabric or film are also used can be. For example, finely woven cloth or cellulose acetate film is used in place of paper usable.

Ein bevorzugter Überzug besteht aus folgenden Bestandteilen: Petrolatum (Schmelzpunkt zwischen 52 und 63°, Viskosität bei 270 zwischen 2500 und 4500 Saybolt-Universal-Sekunden bei einer Scherfähigkeit von 1200 sek.—*'), Paraffin (Schmelzpunkt zwischen 52 und 55°), Pflanzenfaserwachs (Schmelzpunkt ungefähr 780), gelbes Bienenwachs (spezifisches Gewicht 0,95 bis 0,97 bei 15,5°, Schmelzpunkt zwischen 62 und •65°), Ouricurywachs (Schmelzpunkt 79 bis 840) und Naphthene enthaltendes Petroleumöl (Flammpunkt 1770' Mini-, mum, Brennpunkt 204° Minimum, Fließpunkt —23°, Viskosität bei 380 von [Saybolt] 300 bis 325). Diese Stoffe werden in folgenden Gewichtsverhältnissen verwandt:A preferred coating comprises the following constituents: Petrolatum (melting point 52-63 °, viscosity at 27 0 2500 to 4500 Saybolt Universal Seconds at a shear capacity of 1200 sec .- * ') Paraffin (melting point 52-55 ° ), Vegetable fiber wax (melting point approx. 78 0 ), yellow beeswax (specific gravity 0.95 to 0.97 at 15.5 °, melting point between 62 and • 65 °), ouricury wax (melting point 79 to 84 0 ) and petroleum oil containing naphthenes ( Flash point 177 0 'mini-, mum, focus 204 ° minimum, pour point -23 °, viscosity at 38 0 of [Saybolt] 300 to 325). These substances are used in the following weight ratios:

Zusammen 30,1Together 30.1

Mit dieser Masse werden die magnetisierbaren Teilchen, vorzugsweise in Form fein pulverisierter magnetischer Eisenoxyde, fein pulverisierten Eisens oder beider zusammen, vermischt. Es muß so viel magnetisierbares Material zugeführt werden, als die Masse zu halten vermag, ohne ihre Schicht- und Übertragungsmerkmale einzubüßen. Den obenerwähnten 30,1 Gewichtsteilen der Masse können ungefähr 50' Gewichtsteile von entweder Eisenoxyd oder Eisenpulver zugesetzt werden. Die Verhältnisse des magnetisierbaren Materials und der Masse können beträchtlich von dieser Zahl abweichen. With this mass, the magnetizable particles, preferably in the form of finely pulverized magnetic iron oxides, finely powdered iron, or both mixed together. It must as much magnetizable material as the mass can hold without its Loss of layer and transmission characteristics. The aforementioned 30.1 parts by weight of the composition can be about 50 'parts by weight of either Iron oxide or iron powder can be added. The proportions of the magnetizable material and the dimensions can vary considerably from this number.

Das magnetische Eisenoxyd kann in der Schicht magnetisiert und dadurch in magnetisiertem Zustand auf das zu markierende Aufzeichnungsmaterial übertragen werden. Solche Markierungen können als magnetische Stellen durch Standardaufnahmeapparate abgefühlt werden, in welchen solche Markierungen Stromimpulse erzeugen, sobald sie über die Pole eines Elektromagneten gehen. Die nicht magnetisierten Eisenoxydmarkierungen können auf dem Aufzeichnungsmaterial magnetisiert werden, bevor sie abgefühlt werden. Die Eisenpulvermarkierungen können als Felder von erhöhter magnetischer Durchdringlichkeit abgefühlt werden, wogegen sie nicht als magnetische Stellen abgefühlt werden können.The magnetic iron oxide can be magnetized in the layer and thereby in a magnetized state are transferred to the recording material to be marked. Such markings can be sensed as magnetic spots by standard recording devices, in which Such markings generate current pulses as soon as they cross the poles of an electromagnet walk. The non-magnetized iron oxide markings can be found on the recording material magnetized before they are sensed. The iron powder markings can be used as Fields of increased magnetic permeability can be sensed, whereas they are not as magnetic spots can be sensed.

Die magnetisierbare Teilchengröße beträgt im Durchmesser vorzugsweise 1 bis 5 Mikron.The magnetizable particle size is preferably 1 to 5 microns in diameter.

Die Schicht wird mittels einer Beschichtungsmaschine, wie sie z. B. für Kohledurchschreibbeschichtung verwendet wird, in heißem Zustand auf den Bogen aufgetragen.The layer is applied by means of a coating machine such as those described, for example, in US Pat. B. for carbon write-through coating is used, applied to the sheet while it is hot.
