Die bisher bekannten Vorrichtungen zur Registrierung von Zeigerstellungen, bei denen zur Vermeidung einer direkten Berührung zwischen dem Zeiger und der die Registrierung tragenden Unterlage ein elektrischer Funke als Vermittler angewendet wird, sind entweder so eingerichtet, daß dieser Funke kräftig genug ist, um eine sichtbare Marke zu erzeugen, oder so, daß das Papier vorherThe previously known devices for registering pointer positions in which to avoid direct contact between the pointer and the registration supporting base an electrical spark is used as a mediator, are either set up so that this spark strong enough to produce a visible mark, or so that the paper beforehand
ίο mit gewissen chemischen Stoffen versehen wird,- deren elektrolytische Veränderung an der Stelle des Funkenüberganges sichtbar wird. Die letztere Art der Aufzeichnung hat den Vorteil, daß mit wesentlich schwächeren Funken als bei der ersteren gearbeitet werden kann. Bei einer derartigen elektrolytischen Zersetzung ist naturgemäß immer das Vorhandensein einer gewissen Feuchtigkeit notwendig. ίο provided with certain chemical substances - their electrolytic change is visible at the point of the spark transition will. The latter type of recording has the advantage that with much weaker ones Sparks than can be worked with the former. With such an electrolytic Of course, decomposition always requires the presence of a certain amount of moisture.
Diese Feuchtigkeit wurde bisher dem Registrierstreifen von vornherein durch Aufstreichen einer die zu zersetzende Substanz enthaltenden Lösung mitgeteilt, wodurch natürlich die Brauchbarkeit desselben nur für kurze Zeit erhalten blieb.So far, this moisture has been applied to the register strip from the outset communicated a solution containing the substance to be decomposed, whereby of course the usefulness of the same only for remained for a short time.
Nach der vorliegenden Erfindung wird dieser Übelstand nun dadurch beseitigt, daß die nötige Feuchtigkeit durch einen dochtähnlichen Bausch, durch Befeuchtungswalzen usw. dem darüber laufenden Papier erst an der Stelle zugeführt wird, wo die Registrierung erfolgen soll.According to the present invention, this drawback is now eliminated in that the necessary moisture through a wick-like pad, through dampening rollers etc. is fed to the paper running over it only at the point where the registration is made should take place.
Durch die Anwendung des elektrischen Funkens unterscheidet sich die neue Vorrichtung von einem bereits bekannten elektrolytischen Druckverfahren, bei welchem der zu bedruckende Stoff während der mittels geeigneter Matrizen erzeugten Bedruckung ebenfalls über eine Befeuchtungsvorrichtung'läuft. Während bei diesem Verfahren jedoch eine unmittelbare Berührung von Matrize und Druckfläche notwendig ist, wird bei dem Erfindungsgegenstand durch den elektrischen Funken die für eine elektrische Registrierung nötige Trennung der Pole erreicht.The new device differs through the application of the electric spark from an already known electrolytic printing process, in which the material to be printed during the means of suitable Printing generated matrices also runs over a moistening device. While this method requires direct contact between the die and the printing surface, the subject matter of the invention the separation of the poles required for electrical registration is achieved through the electrical spark.
