Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer Gitterelektrode für elektrische Entladungsgefäße, insbesondere nach Art eines Spanngitters, bei der die Drahtenden der Gitterbewicklung nach erfolgter Bewicklung mittels aufgebrachter Tupfen eines Bindemittels festgehalten und die Gitterdrähte anschließend durch ein Metallot an den Gitterholmen befestigt und überzogen werden.The invention relates to a method for producing a grid electrode for electrical discharge vessels, in particular in the manner of a tension grid the wire ends of the lattice wrapping after wrapping by means of applied dots of a Binder held and the grid wires then through a metal solder on the bars attached and covered.
Bei Gitterelektroden für Entladungsröhren wird vielfach eine Befestigung der Gitterdrähte auf den Holmen dadurch vorgenommen, daß die Holme beim Bewickeln gekerbt, die Gitterdrähte in die Kerben eingelegt und diese danach durch Zusammendrücken verschlossen werden. Demgegenüber sind bereits Gitterelektroden bekannt, bei denen die Befestigung der Gitterdrähte mit den Holmen auf andere Weise erfolgt. So kann durch Verlöten, Verschweißen od. dgl. unter Verwendung metallischer Lote eine Befestigung bewerkstelligt werden, die gleichzeitig noch den Vorteil einer besonders guten elektrischen Kontaktgabe bietet. Weiterhin ist es aber auch möglich, Glaslot zur Befestigung der Gitterdrähte zu verwenden.In the case of grid electrodes for discharge tubes, the grid wires are often attached to the Holmen made in that the bars notched when winding, the grid wires in the notches inserted and these are then closed by pressing together. In contrast, are already Known grid electrodes in which the attachment of the grid wires to the spars in a different way he follows. An attachment can be made by soldering, welding or the like using metallic solders be accomplished, which at the same time still has the advantage of a particularly good electrical contact offers. However, it is also possible to use glass solder to attach the grid wires.
Bei der Herstellung von Gitterelektroden nach Spanngitterart wird im allgemeinen so verfahren, daß die Gitterholme durch Querverstrebungen zu einem starren Spannrahmen vereinigt werden. Dieser rahmenartige Bauteil kann dann mit den Gitterdrähten bewickelt werden. Nach Beendigung der Bewicklung wird in der oben geschilderten Weise ein Verlöten der Drähte vorgenommen.In the production of grid electrodes according to the tension grid type, the procedure is generally such that the lattice bars are combined into a rigid tensioning frame by cross bracing. This frame-like The component can then be wrapped with the grid wires. After finishing the wrapping the wires are soldered in the manner described above.
Dabei besteht aber die Schwierigkeit, daß der Anfang und das Ende des Wickeldrahtes in dem Zeitraum zwischen der Beendigung des Wickelvorganges und dem Beginn der Lötung keinen festen Halt besitzen. However, there is the difficulty that the beginning and the end of the winding wire in the period have no firm hold between the end of the winding process and the start of soldering.
Zur Festlegung der Drahtenden ist es bekannt, als Bindemittel eine Amyl-Acetat-Lösung zu verwenden. Die Amyl-Acetat-Lösung hat den Nachteil, daß sie bei hohen Temperaturen, insbesondere bei Metall-Lötung, ihre Bindeeigenschaft verliert. Deshalb kann dieses Bindemittel nur dann zur Festlegung der Drahtenden verwendet werden, wenn das zur Befestigung der Gitterwindungen auf den Holmen verwendete Lot die Aufgabe des Bindemittels, nämlich die Festlegung der Drahtenden während des Lötvorganges übernimmt. Bisher ist nur Glaslot bekannt, das dieser Forderung entspricht. Bei der Spanngitterherstellung ist es aber zur Unterdrückung der Gitteremission erwünscht, eine Vergoldung des Gitters vorzunehmen. Deshalb wird zweckmäßig die Befestigung der Gitterwindungen an den Holmen durch Goldlot gleichzeitig mit der Vergoldung vorgenommen.To fix the wire ends, it is known to use an amyl acetate solution as a binding agent. The amyl acetate solution has the disadvantage that at high temperatures, especially with metal soldering, loses its binding property. Therefore this binder can only be used to fix the wire ends used if the solder used to attach the lattice windings to the spars takes on the task of the binding agent, namely the definition of the wire ends during the soldering process. So far, only glass solder is known that meets this requirement. In the manufacture of tensioning grids however, in order to suppress the grating emission, it is desirable to gold-plating the grating. It is therefore advisable to fasten the lattice windings to the spars with gold solder at the same time made with the gilding.

Das wesentliche Merkmal des erfindungsgemäßen Bindemittels besteht darin, daß das Bindemittel aus mit Äthylalkohol verdünntem Aluminiumoxyd mit einem Zusatz von Aluminiumnitrat besteht.The essential feature of the binder according to the invention is that the binder consists of aluminum oxide diluted with ethyl alcohol with an addition of aluminum nitrate.

Die als Spanngitter ausgebildete Gitterelektrode besitzt zwei runde Holme 1 und 2 aus Molybdän od. dgl., welche durch die Querverstrebungen 3, 4 und 5, 6 zu einem starren Spannrahmen vereinigt sind. Die Gitterdrähte 7, deren Stärke beispielsweise 8 μ beträgt, sind als straffe Bewicklung auf dem Spannrahmen aufgebracht und beispielsweise mit einem Goldlot mit den Holmen verfestigt. Zur Sicherung der Drahtenden 8 und 9 der Bewicklung dienen die beiden Tupfen 10 und 11 aus Aluminiumoxyd. Während in manchen Fällen beim Ausheizen bzw. Verlöten des Gitters der Tupfen sich verflüchtigt oder verlorengeht oder durch Wegbrechen od. dgl. entfernt wird, kann er in anderen Fällen erhalten bleiben.The grid electrode, designed as a tensioning grid, has two round bars 1 and 2 made of molybdenum or the like, which are combined by the cross braces 3, 4 and 5, 6 to form a rigid tensioning frame. The grid wires 7, the thickness of which is 8 μ, for example, are applied as a tight wrapping on the clamping frame and, for example, solidified with the bars with a gold solder. The two dots 10 and 11 made of aluminum oxide serve to secure the wire ends 8 and 9 of the wrapping. While in some cases the dots are volatilized or lost when the grid is baked or soldered, or removed by breaking away or the like, it can be retained in other cases.
