Abstract: The invention relates to a method for producing noble metal nets on flatbed knitting machines, the steps involving—providing noble metal wire comprising platinum—providing yarn that is combustible or soluble in solvent—knitting two-bed items by simultaneous knitting on the front and rear needle beds and joining the two knitted fabrics by means of connecting pile threads, wherein, on the front or on the rear needle bed, a combustible or soluble yarn is used which is burnt off or dissolved after the knitting process, and a noble metal wire is used on the other needle bed and for the pile threads such that, after the combustible or soluble yarn has been burnt off or dissolved, there remain only the pile threads and the knitted fabric made of noble metal wire and produced on the rear or front needle bed.

Abstract: The invention relates to a precious metal mesh which is knitted on a flat-bed knitting machine, having at least two float stitches per wale, thus having a significantly higher density for a given latch needle density of the flat-bed knitting machine than the precious metal mesh according to the prior art.

Abstract: Disclosed is a nuclear reactor plant, comprising:a prestressed concrete pressure vessel;a high temperature reactor arranged in a central cavity within the vessel;a closed gas cooling circuit including at least one housed gas turbo unit arranged in a turbine duct in the wall of the vessel, said unit including a turbine and a compressor and having detachable bearings; means for exchanging heat and means for transporting gas in the cooling circuit including hot gas from the reactor to the turbine, said heat exchange means and said gas transport means being arranged in recesses in the wall of the vessel;means for forming a detachable plug-in type connection between the hot gas transport means and each turbo unit;means, positioned at the edge of the turbine duct, for connecting all remaining gas transport means to the turbo unit;means, including peripheral sealing members positioned between the inside wall of the turbine duct and the outer housing of the turbo unit, for separating each of the remaining gas transpo
