 den Erfindungsgegenstand bildende Verfahren bezweckt nun die Behebung dieses Nachteiles. Seinem Wesen nach besteht dieses Verfahren darin, dass aus Zement   hergestellte Gegenstände   mit dem pech-   artigen Rückstände getränkt werden,   der in bekannter Weise durch Ansäuern oder durch Destillieren der verhältnismässig leichten Öle erhalten wird, die nebst einem festen Niederschlag bei der Behandlung von Teer mit einem geringen Zusatz von Schwefelsäure entstehen. Die genannten Öle können   nämlich

Er eignet sieh hiezu sehr gut, da er bei Temperaturen über   1500   C leichtilüssig wie   Wasser,   bei normaler Temperatur dagegen fest und übeidies vollkommen wasserfest ist und eine hohe Isolierfähigkeit besitzt (eine 1 mm dicke Schicht desselben widersteht einem

 EMI1.1
 The method forming the subject of the invention now aims to remedy this disadvantage. In essence, this method consists in that objects made of cement are soaked with the pitch-like residue, which is obtained in a known manner by acidification or by distilling the relatively light oils, which, in addition to a solid precipitate when treating tar with a low addition of sulfuric acid. The oils mentioned can namely

 Residue are broken down (Bt.

   Patent No. 16908 from 1909 and No. 3008 from 1912), which the latter is used according to the invention as an impregnating agent to make the cement objects in question well insulated. It is very suitable for this purpose, since it is easily liquid like water at temperatures above 1500 C, but solid at normal temperature and, moreover, completely waterproof and has a high insulating capacity (a 1 mm thick layer of it is resistant to you

 for the objects to be soaked. The prann @ s are appropriately arranged in such a way that they are connected to each other in pairs and work with alternating pressure.

   Satisfactory

   Device is to be pulled. The insulating material produced according to the invention gives excellent results, and when the objects have been impregnated with the aforementioned soluble residue, the insulator is. as it turned out. a voltage of 10,000-] 5. 000 volts per millimeter. It is well known to treat artificial stones with tar, pitch, etc. to soak, but that is
