Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist bekannt, daß Gefäße aus Porzellanerde oder gebranntem Ton bei plötzlichem Temperaturwechsel leicht zerspringen. Der Grund hierfür liegt in den ungleichen Spannungen, die in den Gefäßwandungen auftreten, wenn solche Temperaturwechsel vorkommen. Um diesem Übelstande zu begegnen, sollen nach vorliegender Erfindung die Gefäße in drei Schichten hergestellt werden, wovon dieIt is known that vessels made of china clay or baked clay will suddenly Temperature change easily shatter. The reason for this lies in the unequal tensions, which occur in the vessel walls when such temperature changes occur. To counter this evil, should According to the present invention, the vessels are made in three layers, of which the

ίο mittlere Schicht porös ist. Diese Herstellung der Gefäße kann z. B. mittels Gipsformen im bekannten Gießverfahren erfolgen. Die Zeichnung stellt ein Gefäß beliebiger Form im Querschnitt dar. Die erste Gußschicht a besteht aus feuerfestem Ton bezw. Porzellanerde, die zweite Gußschicht b aus porösem Ton oder Porzellan. Diese poröse Schicht kann auf irgendeine bekannte Weise hergestellt werden, z. B. aus bituminösem Ton oder aus Ton mit Zusätzen von Sand, Chamotte, Sägespänen, Kohle usw. Die dritte, innere Schicht al besteht aus demselben Materiale wie die äußere Schicht a. Bei dieser Zusammensetzung der Gefäße werden die bei jähem Temperaturwechsel auftretenden Spannungen der Gefäßwandungen durch die mittlere poröse Schicht abgeleitet, verteilt und unschädlich gemacht.ίο middle layer is porous. This production of the vessels can, for. B. be done by means of plaster molds in the known casting process. The drawing shows a vessel of any shape in cross section. The first cast layer a consists of refractory clay BEZW. China clay, the second casting layer b made of porous clay or porcelain. This porous layer can be made in any known manner, e.g. B. bituminous clay or clay with additions of sand, chamotte, sawdust, coal, etc. The third, inner layer a 1 consists of the same material as the outer layer a. With this composition of the vessels, the stresses on the vessel walls that occur with sudden temperature changes are diverted, distributed and rendered harmless by the central porous layer.
