Description

Vorrichtung zur Anzeige von in regelmäßigen Zeitabständen sich wiederholenden Echovorgängen Die Erfindung bezieht sich auf eine Vorrichtung zur Anzeige von in regelmäßigen Zeitabständen sich wiederholenden Echovorgängen durch Helligkeitskeitssteuerung von Kathodenstrahlröhren, insbesondere mit langer Nachleuchtdauer, mit Strahlablenkung durch ein Kippgerät und mit einer vom Kippgerät gesteuerten Einrichtung zur Unterdrückung der Aufhellspannung bei Ausfall der Kippspannung für das Ablenkfeld. Die bekannten Vorrichtungen dieser Art arbeiten mit Relaisschaltungen zum Schutz der Kathodenstrahlröhre gegen Einbrennschäden. Derartige Relaisschaltungen haben den Nachteil unerwünscht hohen Aufwandes und einer Ansprechverzögerung, die bei schnell verlaufenden Vorgängen besonders nachteilig sein kann.Device for displaying at regular time intervals repeating Echo processes The invention relates to a device for displaying in echo processes repeating at regular intervals through brightness control of cathode ray tubes, especially those with a long afterglow period, with beam deflection by a tilting device and with a device for suppression controlled by the tilting device the clearing voltage in the event of failure of the breakover voltage for the deflection field. The known Devices of this type employ relay circuits to protect the cathode ray tube against burn-in damage. Such relay circuits have the disadvantage of undesirable high effort and a response delay, which is the case with fast-running processes can be particularly detrimental.

Diese Mängel lassen sich erfindungsgemäß dadurch vermeiden, daß ein Ladekreis zur Erzeugung einer Entriegelungsspannung für den Echoverstärker durch Differenzierung der Kippschaltung bzw. des Kippstromes vorgesehen ist. Eine solche Schaltung hat sowohl den Vorteil großer Einfachheit als auch geringer Trägheit und hoher Betriebssicherheit. These deficiencies can be avoided according to the invention in that a Charging circuit for generating an unlocking voltage for the echo amplifier Differentiation of the trigger circuit or the breakover current is provided. Such Circuitry has the advantage of both great simplicity and low inertia and high operational reliability.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel einer Vorrichtung nach der Erfindung. The drawing illustrates an embodiment of a device according to the invention.

Zur Hellsteuerung der Blauschriftröhre 1 ist eine Verstärkerröhre 2 vorgesehen, an deren Hauptsteuergitter ein Echoverstärker 3 liegt, von dem Nutzsignale zur Blauschriftröhre geschaltet werden. Das Zeilenraster für das Echogramm wird von einem Kippteil 4 erzeugt. Dessen Kippspannung wird auf eine Hintereinanderschaltung zweier Röhren 5 und 6 gegeben, an die eine Ablenkspule 7 für den Kippüberlauf in üblicher Weise angeschlossen ist. Die Spannung über dieser Spule wird differenziert. Dazu dient beispielsweise ein Kondensator 8 und Widerstand 9. Die differenzierte Spannung über dem Widerstand 9 wird dem zweiten Steuergitter der Röhre 2 zugeführt. Nur solange dieses Gitter nicht verriegelt ist, d. h. solange ein sich positiv ändernder Strom durch die Spule 7 fließt, ist die Röhre 2 in der Lage, die Aufhellung durch Signale vom Echoverstärker 3 zu bewirken. An amplifier tube is used to control the brightness of the blue writing tube 1 2 provided, at the main control grid of which an echo amplifier 3 is located, from the useful signals can be switched to the blue writing tube. The line grid for the echogram is generated by a tilting part 4. Its breakover voltage is based on a series connection two tubes 5 and 6 given, to which a deflection coil 7 for the tilt overflow in connected in the usual way. The voltage across this coil is differentiated. A capacitor 8 and resistor 9, for example, are used for this purpose. The differentiated Voltage across resistor 9 is fed to the second control grid of tube 2. Only as long as this grid is not locked, i.e. H. as long as a positively changing one Current through the coil 7 flows, the tube 2 is able to carry out the lightening To effect signals from the echo amplifier 3.
