Patentansprüche:Patent claims: 1. Verfahren zur Bildzusammensetzung beim Fernsehen mit Hilfe einer Braunschen Kathodenstrahlröhre, dadurch gekennzeichnet, daß der nur durch eine Wechselspannung längs der Zeilenrichtung bewegte Kathodenstrahl selbst nach Beendigung seines Laufes über eine Bildzeile seine Rückführung auf den Anfang der nächstfolgenden Bildzeile bzw. nach Beendigung des ganzen Bildes auf den Anfang des nächsten verursacht. 1. Method for image composition in television with the help of a Braunsche Cathode ray tube, characterized in that the only by an alternating voltage along the line direction the cathode ray moved its return even after the end of its run over an image line to the beginning of the next line of the image or, after completion of the entire image, to the beginning of the next. 2. Einrichtung zur Ausübung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, daß innerhalb einer Braunschen Röhre eine Elektrode angebracht ist, bei deren Berührung durch den Kathodenstrahl die gewünschte Rückführung verursacht wird.2. Device for performing the method according to claim 1, characterized in that that an electrode is attached within a Braun tube, when it is touched by the cathode ray causing the desired feedback.
