Abstract: An isolation transformer for a cathode heater supply for a microwave source has a first U- shaped secondary winding (421), comprising two parallel leg portions joined at one end thereof by a bridging portion. A primary winding (422) is located around and concentric with a portion the bridging portion. A monitor winding passes through primary core assemblies of the primary winding. Electrical insulation (115) insulates the secondary winding from the primary winding. For a DC cathode heater supply a second U-shaped secondary winding is spaced from and aligned with the first U-shaped secondary winding and first and second smoothing chokes comprising respective core assemblies (1127, 1129) are fitted over connection leads arranged for connecting two ends of the first secondary winding to the cathode heater. Synchronised rectifiers are connected between the secondary windings and the first smoothing choke; and control means are provided for the synchronised rectifiers.

Abstract: A power supply for a video display tube includes a deflection transformer with a primary winding powered with a scan voltage which has a first value when displaying signal according to a first video standard and a second voltage when displaying video according to a second standard. A secondary winding of the transformer produces filament voltage for the display tube. A variable coupler couples the filament voltage to the filament of the picture tube in an amount established by a control signal. A memory produces a first control signal in response to the first scan voltage and a second control signal in response to the second scan voltage. The first and second control signals are selected so that the voltage coupled from the transformer to the filament is the same at both scan voltages.

Abstract: Die Erfindung betrifft eine verbesserte Röhre (100), insbesondere eine Elektronenröhre, und ein verbessertes System zur Ansteuerung der Elektroden und/oder der Heizung einer Röhre sowie zur Bestimmung der Lebensdauer einer Röhre. Eine erfindungsgemäße Röhre (100) weist einen evakuierten oder gasgefüllten Bereich (110) auf, in welchem eine oder mehrere Elektroden (140, 190) sowie Mittel (150) zur Messung der Temperatur einer der Elektroden (140, 190) angeordnet sind. Der Vorteil der vorliegenden Erfindung ist darin zu sehen, daß mit verhältnismäßig geringem Aufwand eine präzise Ermittlung der Elektrodentemperatur einer Röhre (100) erfolgen kann. Dadurch kann zum einen die Lebensdauer der Röhre genauer vorhergesagt werden. Andererseits ist es durch Überwachen der Elektrodentemperatur und entsprechendes Ansteuern der Elektroden und/oder der Elektrodenheizung möglich, die Elektrodentemperatur exakt auf einem gewünschten Wert (Sollwert) zu halten.

Abstract: Dispositif de chauffage de la cathode d'un tube de puissance, destiné, en particulier, à éviter d'endommager le tube à la mise sous tension.
La valeur efficace du courant de chauffage fourni à la cathode K d'un tube T est commandée par des thyristors D,, D 2 dont l'angle d'ouverture est réglé par la valeur d'une tension U. Lors de l'allumage du tube cette tension U part de la valeur O et atteint progressivement, avec une constante de temps donnée par les éléments du circuit, une valeur U o correspondant à un régime de préchauffage du tube: elle reste à cette valeur U o sous la commande d'un relais G 2 ou atteint progressivement une valeur supérieure U m , si le relais G 2 n'est pas alimenté, amenant ainsi progressivement la cathode du tube à sa température normale de fonctionnement.
Application, en particulier, aux émetteurs comportant des tubes de puissance.

Abstract: A vacuum electron device (50) for generating signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field produced by a magnet in the RF section of a tube. After the electrons have passed through the active area of the tube, the electrons strike a collector which, preferably, is a multistage depressed collector. The stages of the depressed collector maybe connected to high energy voltage sources of different potentials. A vacuum electron device (50) with a multistage depressed collector is used here for the first time in a ground based satellite or terrestrial communications system.

Abstract: A dish-shaped dispenser cathode (28) is mounted at one end of a cathode housing (10), with a heater wire coil (42) mounted behind the cathode (28). A warm-up power supply (70) electrically connected between the central region and the periphery of the cathode (28) causes heating current to flow through the cathode (28) during a short period of time at the start of cathode operation to provide rapid warm-up of the cathode (28). A sustaining power supply (76) electrically connected between the respective ends of the heater wire coil (42) causes sustaining current to flow through the heater wire coil (42) to provide sustaining heat to the cathode (28) by radiation from the heater coil (42) to maintain the cathode (28) at its desired operating temperature.
