Description

Verfahren zur Herstellung von Lenard-Fenstern mit versteifendem Rippensystem Nach einem früheren bisher unveröffentlichten Vorschlage sollen die in bekannter Weise aus einer dünnen Metallhaut und einem versteifendenRippensystem bestehenden Lenard-Fenster für Kabhodenstrahlenröhren aus einem durch Kathodenzerstäubung erzeugten Metallniederschlag hervorgebracht werden, insbesondere in der Weise, @daß zunächst das Versteifungssystem gebildet und hernach - nach Ausfüllung der Zwischenräume des Versteifungssystems mit einem neutralen in Wasser löslichen Stoff -durch Aufsprühen von Metall auf die so entstandene, teils metallische, teils nichtmetallische Oberfläche die Metallhaut erzeugt wird.Process for the production of Lenard windows with a reinforcing rib system According to an earlier previously unpublished proposal, those in well-known Way consisting of a thin metal skin and a stiffening rib system Lenard window for cabbage tubes made from a cathodic sputtering Metal precipitation are produced, especially in such a way that @ that initially the stiffening system formed and afterwards - after filling the gaps of the stiffening system with a neutral substance soluble in water - by spraying on from metal to the resulting partly metallic, partly non-metallic surface the metal skin is generated.

Erfindungsgemäß wird umgekehrt verfahren. Man erzeugt zunächst auf einer ebenen oder gekrümmten Fläche, welche die Oberfläche des Lenard-Fensters bestimmt, durch Aufsprühen von fein verteiltem Metall auf dem Wege der Kathodenzerstäubung oder aber auch galvanostegisch die dünne Metallhaut. Alsdann legt man einen als Lehre zu bezeichnenden Festkörper aus neutralem Stoff, z. B. Wachs, auf, welcher aus durch schmale Zwischenräume getrennten Blöcken besteht und mit diesen Zwischenräumen die Bildung der versteifenden Rippen vorschreibt, auch durch seine eigene Dicke die Höhe der Rippen bestimmt. Nunmehr setzt man die Bildung des Metallniederschlages 'fort und erhält so das versteifende Rippensystem. Bei dieser Arbeitsweise bedarf es zwischen den beiden Niederschlagsvorgängen zur Bildung der Metallhaut und zur Bildung der Rippen keiner irgend-,vie gearteten Bearbeitung des zuerst erzeugten Niederschlages, und es besteht vollkommene Sicherheit, daß sich der Metallniederschlag allenthalben unmittelbar an den ersten metallisch anschließt. Das beschriebene Verfahren eignet sich auch besser zur Herstellung von Fenstern mit stark gekrümmter Fläche.According to the invention, the procedure is reversed. First you generate a flat or curved surface that defines the surface of the Lenard window, by spraying on finely divided metal by means of cathodic sputtering or also the thin metal skin galvanostegically. Then you put one as Teaching to be designated solid body made of neutral material, z. B. wax, which one consists of blocks separated by narrow spaces and with these spaces dictates the formation of the stiffening ribs, also by its own thickness determines the height of the ribs. The formation of the metal precipitate is now set 'and thus preserves the stiffening rib system. This way of working requires between the two precipitation processes for the formation of the metal skin and for Formation of the ribs no processing whatsoever of the first produced Precipitation, and there is absolute certainty that the metal precipitate everywhere directly connected to the first metallic. The procedure described is also better suited for the production of windows with strongly curved surfaces.
