    摘要： A multi stage process for the production of polycarbonates having low monomer content is disclosed. The process entails, in sequence, (i) transesterifying in the melt at least one dihydroxyaryl compound with at least one diaryl carbonate in the presence of at least one onium catalyst to produce a polycondensate that contains monomers, (ii) introducing into the polycondensate an inhibitor in an hypostoichiometric amount in relation to the catalyst and (iii) reducing in a finishing reactor the content of monomers in said polycondensate. The polycarbonate thus produced is characterized in that it contains less than 350 ppm of diphenyl carbonate, less than 40 ppm of 2,2-bis-(4-hydroxyphenyl)propane and less than 150 ppm of phenol.

    摘要： A press for compressing elongated radioactive structural elements, with theress having a horizontal press shaft and a removable counterpunch in place of which a transfer shaft can receive a finished pressed object. The press is remotely operable, has a minimum overall length, and assures that during compression as well as insertion of the pressed object into the transfer shaft, no small particles can escape from the press line and that the unavoidable swelling of the pressed object in the axial direction has no impact upon removal of the counterpunch and insertion of the pressed object into the transfer shaft. The press ram includes several insertable press ram sections, and the cover is divided into several cover portions. The horizontal press shaft is movably disposed in the pressing direction on a mounting base between two crosspieces interconnected by tie rods. Via a displacement drive, the press shaft is brought to rest against the counterpunch for the compression process, and against the transfer shaft for the ejection process. To insert the counterpunch and remove a loaded transfer shaft, the press shaft is retracted far enough to provide a free space.
