Description
Einrichtung zum Schalten des Stators von Drehanodenröhren Bei Drehanodenröhren leidet bei den hohen Umdrehungszahlen der Anode das Lager sehr. Es ist bekannt, die Anode nach jeder Aufnahme sofort selbsttätig auszuschalten. Dies allein genügt aber nicht, denn die Anode hat schon an sich einen Auslauf von 2 bis 3 Minuten, während :die Aufnahmezeit nur einen kleinen Bruchteil einer Sekunde beträgt.Device for switching the stator of rotating anode tubes With rotating anode tubes The bearing suffers greatly at the high number of revolutions of the anode. It is known, automatically switch off the anode immediately after each exposure. That alone is enough but not, because the anode itself has an outlet of 2 to 3 minutes, while: the recording time is only a small fraction of a second.
Erfindungsgemäß soll nun selbsttätig nach jeder Aufnahme z. B. durch die vorhandene oder eine zweite Schaltuhr nach dem Ende der Belichtungszeit und damit nach dem Ausschalten des Röhrenstromes der Statorstrom kurz um- und dann erst ganz ausgeschaltet werden, so daß die Anode sehr schnell zum Stillstand kommt. Die Schaltvorgänge lassen sich mit den bekannten Mitteln, Schütze und Zeitrelais, leicht vornehmen: Will der Untersucher Serienaufnahmen machen, so wird zweckmäßig der Ausschalt-und Gegenstrom. vom Leuchtschirm aus zweckmäßig durch einen Schütz unterbrochen oder durch ein Zeitrelais verzögert, so daß erst nach der letzten Aufnahme die Um- und Ausschaltung erfolgt. So erfolgt ein Ausschalten des Stators auch dann, wenn der Untersucher vergißt, den-hierzu nötigen Stromkreis wieder zu schließen. Das Schützrelais kann so eingerichtet sein, daß .die Unterbrechung und Ausschaltung des Gegenstromes immer wieder selbsttätig nach Ablauf einer einstellbaren, wenige Sekunden betragenden Zeit aufgehoben wird.According to the invention should now automatically after each recording z. B. by the existing or a second timer after the end of the exposure time and so that after switching off the tube current, the stator current briefly changes and only then completely switched off, so that the anode comes to a standstill very quickly. the Switching operations can be easily carried out using the known means, contactors and timing relays make: If the examiner wants to take series exposures, it is advisable to switch off and Countercurrent. Appropriately interrupted from the fluorescent screen by a contactor or delayed by a time relay, so that the changeover and Switch-off takes place. The stator is switched off even if the The examiner forgets to close the circuit required for this. The contactor relay can be set up in such a way that .the interruption and deactivation of the countercurrent again and again automatically after an adjustable period of a few seconds has elapsed Time is canceled.
