  • Publication number: 20050186436
    Abstract: Coating compositions for producing sol-gel coatings that include: a) one or more alkoxysilyl-containing oxalamides of the general formula (II), where R? is hydrogen or an organic C1-C10 radical, R? radicals are organic, optionally oxygen-attached C1-C10 radicals, R is an oxygen-attached radical optionally containing one or more ether groups and having 1 to 30 carbon atoms and n is an integer between 0 and 2, b) optionally further crosslinkers, c) one or more catalysts and d) water. The sol-gel coatings are produced by a method that includes combining a silica sol and one or more alkoxysilyl-containing oxalamides. The sol-gel coatings obtained from the above-described coating compositions can be used to coat substrates.

  • Publication number: 20040231741
    Abstract: The invention relates to a vacuum-insulated filling line, especially for cryogenic media, preferably for liquefied and/or gaseous, highly-pressurized hydrogen. The invention also relates to a filling station for cryogenic media, having said vacuum-insulated filling line. According to the invention, the vacuum-insulated filling line has a pipe fracture safety. Said pipe fracture safety can be embodied in the shape of a guide pipe (5) arranged on the outer wall (1) of the filling line, a bellows (6) arranged in the guide pipe (5) and firmly connected to the outer wall (1) of the filling line, a (contact) plate (7) closing the bellows (6) and a device assigned to the (contact) plate (7), which is configured to detect movement of the (contact) plate (7) and/or the bellows (6).
