Patentansprüche:Patent claims: 1. Einrichtung an Kathodenstrahloszillographen zur Einführung einer lichtempfindlichen Schicht in das Vakuum der Röhre, dadurch gekennzeichnet, daß ein Spalt in der Röhre vorgesehen ist, durch welchen die lichtempfindliche Schicht eingeführt wird und eine Pumpe großer Leistung, mittels welcher die durch vorhandene Undichtigkeiten eintretenden Gase dauernd entfernt werden.1. Set up on cathode ray oscillographs for the introduction of a light-sensitive Layer in the vacuum of the tube, characterized in that a gap is provided in the tube through which the photosensitive layer is introduced and a high-performance pump by means of which the through any leaks in the gas are permanently removed. 2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Begrenzungsflächen des Spaltes mit gegeneinander versetzten evakuierbaren Nuten versehen sind.2. Device according to claim 1, characterized in that the boundary surfaces of the gap provided with mutually offset evacuable grooves are. 3. Einrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß eine umlaufende Auflagefläche für die photographische Schicht geschaffen ist, die mit umlaufenden evakuierbaren Nuten versehen ist.3. Device according to claim 1 or 2, characterized in that a circumferential Support surface for the photographic layer is created with the circumferential evacuable grooves is provided. 4. Einrichtung nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß an einem der Auflagefläche gegenüberliegenden Teile, der von der Auflagefläche um annähernd die Dicke der lichtempfindlichen Schicht entfernt ist, umlaufende evakuierbare Nuten angeordnet sind.4. Device according to claim 1 to 3, characterized in that one of the Support surface opposite parts of the support surface by approximately the thickness of the photosensitive layer is removed, circumferential evacuable grooves are arranged. 5. Einrichtung nach Anspruch 3 und 4, dadurch gekennzeichnet, daß die Nuten an eine zur Röhre gehörige Vorvakuumpumpe angeschlossen sind.5. Device according to claim 3 and 4, characterized in that the grooves on a backing pump belonging to the tube is connected. *) Von dem Patentsucher ist als der Erfinder angegeben worden: *) The patent seeker stated as the inventor: Dn Hans Gerdien in Berlin-Grunewald.
