Patentirt im Deutschen Reiche vom 5. December 1877 ab.Patented in the German Empire on December 5, 1877.
Die bisher angewendeten Mittel zur Verhütung des Rosten von Stahlplatten, Federn, schwache Silber-, Gold- und Kupferplattirung haben sich auf die Dauer nicht bewährt, da dieselben in kurzer Zeit von der in jedem Wasser mehr oder weniger enthaltenen Säure vernichtet worden sind. Bei dem nach beiliegender Zeichnung construirten Apparat wird Quecksilber vermittelst des entstehenden Druckes gegen bezw. in die Feder gedrückt und hierdurch jede Oxydation und Ueberhitzung, sogar Erwärmung, vermieden.The means previously used to prevent rusting of steel plates, springs, weak Silver, gold and copper plating have not proven themselves in the long run, since they are in have been destroyed in a short time by the acid more or less contained in every water. In the apparatus constructed according to the accompanying drawing, mercury is brought about by the resultant Pressure against respectively. pressed into the spring and thereby any oxidation and overheating, even heating, avoided.
Letzteres ist durch praktische Versuche in der Maschinenfabrik der Herren P. Suckow & Comp, in Breslau dahin erwiesen worden, dafs, wenn die Erwärmungsfläche (quadratischer Inhalt des Quecksilbers) im Verhältnifs zur Abkühlungsfläche des Apparats circa 1—15 beträgt, eine Wärmeleitung des Quecksilbers nicht stattfindet und hierdurch ein Warmwerden der Feder ausgeschlossen ist.The latter is through practical experiments in the machine works of Mr. P. Suckow & Comp, has been shown in Breslau to the effect that if the heating surface (square content of mercury) in relation to the cooling surface of the apparatus is about 1-15, one Thermal conduction of the mercury does not take place and this prevents the spring from becoming warm is.
Der ganze Apparat besteht aus Gufseisen, das Kugelventil α aus Wärme widerstehendem Hartgummi, das Kugelventil b aus Eisen.The whole apparatus is made of cast iron, the ball valve α made of heat-resistant hard rubber, the ball valve b made of iron.
Letztere Ventile haben den Zweck, bei eintretendem Vacuum im Kessel ein Zurücktreten des Quecksilbers in denselben zu vermeiden.The latter valves have the purpose of receding when a vacuum enters the boiler to avoid mercury in the same.
Vor Inbetriebsetzung ist der Apparat durch die Füllöffnung c mit Quecksilber anzufüllen, welches letztere bei entstehendem Druck an bezw. in die Feder gedrückt wird, infolge dessen kommen weder Wasser noch Luft mit der Feder in Berührung, also kann eine Oxydation und Erwärmung der Feder nicht stattfinden.Before starting up, the apparatus is to be filled with mercury through the filling opening c. is pressed into the spring, as a result of which neither water nor air come into contact with the spring, so oxidation and heating of the spring cannot take place.
Die Zeichnung zeigt einen Apparat unter Druck gestellt.The drawing shows an apparatus put under pressure.
