Description

Gefäße, in denen Wasser und andere Flüssigkeiten eingeschlossen sind und welche gleichzeitig vollkommen dicht sein müssen, werden mit Vorteil zur Herstellung eines vollkommen luftdichten Abschlusses mit Zinnoder Hartlot verlötet. An Gefäßen dagegen, in welchen Quecksilber enthalten ist, insbesondere aber an solchen Gefäßen, in denen Quecksilberdämpfe entstehen, ist ein Abschluß ίο durch derartige Lötmittel nicht ohne weiteres verwendbar, da dieselben vom Quecksilber angegriffen werden und nach kurzer Zeit die Dichtung nicht mehr aufrechterhalten können. Der Inhalt der vorliegenden Erfindung besteht nun darin, auch für Metalldampf gleichrichter Lötungeiv zum Abschluß zwischen Gefäß und Deckel dadurch verwendbar zu machen, daß ein zweiter Vorabschluß geschaffen wird, welcher dem ausschließlichen Zwecke dient, die Metalldämpfe von den Lötstellen fernzuhalten.Vessels in which water and other liquids are enclosed and which must be completely tight at the same time, are with advantage for producing a perfect airtight seal soldered with tin or hard solder. On the other hand, in vessels in which mercury is contained, in particular But in such vessels, in which mercury vapors arise, a termination ίο by such solder is not straightforward usable, since the same are attacked by the mercury and after a short time the Seal can no longer be maintained. The content of the present invention is now in it, also for metal vapor rectifier Lötungeiv to terminate between vessel and to make the lid usable by creating a second preliminary closure which is exclusive to the The purpose is to keep the metal fumes away from the soldered joints.

Eine Ausführungsform der Erfindung ist in der Figur angegeben, α sei die Wand des Gefäßes, b der Deckel. Am Deckel sowohl wie am Gefäß werden Ringe r angedreht, angelötet oder angeschweißt, welche an der Stelle c mit Zinnlot zusammengelötet werden. Um die Lötverbindung schnell lösen zu können, ist ein Draht d eingezogen, mit Hilfe dessen beim Erwärmen das Lötmetall weggenommen werden kann. In dem Gefäß ist eine Nut η vorgesehen, welche mit Asbest, Asphalt oder einem anderen Dichtungsmittel ausgegossen oder auch durch Einschleifen dicht gehalten werden kann. Gleichzeitig kann in der Nähe der Nut η ein Kühlraum k angebracht sein, welcher auch dann noch verhindert, daß die Dämpfe zur Lötstelle hinüberwandern, wenn an dem Vorabschluß kleine Undichtigkeiten vorhanden sind, dadurch, daß die Dämpfe vorher kondensiert werden. Der Raum zwischen Haupt- und Vorabschluß kann besonders ausgepumpt werden.An embodiment of the invention is shown in the figure, α is the wall of the vessel, b the lid. Rings r are turned, soldered or welded onto the lid as well as the vessel, which are soldered together at point c with tin solder. In order to be able to loosen the soldered connection quickly, a wire d is drawn in, with the aid of which the soldering metal can be removed when it is heated. A groove η is provided in the vessel, which can be filled with asbestos, asphalt or some other sealant, or it can be kept tight by grinding. At the same time, a cooling space k can be attached near the groove η , which prevents the vapors from migrating over to the solder joint if there are small leaks at the preliminary termination, by condensing the vapors beforehand. The space between the main and preliminary accounts can be especially pumped out.
