Abstract: Substituted phenols and phenyl carbonates derived therefrom, such as 2,4-dinitrophenol and 2,4-dinitrophenyl carbonate, are employed to inhibit the formation of linear polycarbonates from cyclic polycarbonate oligomers. Inhibi­tion of polymerization initiated by impurities in the cyclics is noted. When polymerization is effected by basic polycarbonate formation catalysts, the phenols or phenyl carbonates decrease reaction rate.

Abstract: The method serves to dress grinding wheels (10) whose surface (16) is provided with an embedding compound for CBN-crystals. A rotating dressing roll (11) is guided along the oppositely rotating surface (16) of the grinding wheel (10). 
<??>In order to produce sharp-edged tips on the CBN-grains (20) during dressing and to obtain sufficiently large intermediate spaces between the CBN-crystals (20) as chip spaces in the embedding compound, the dressing roll (11) is guided at least twice along the surface (16), the dressing roll (11) being guided the first time at a first, high feed rate (v3) in such a way that dressing crystals of the dressing roll (11) elastically deflect the CBN-grains (20) but set back the embedding compound, whereas the dressing roll (11) is guided the second time at a second, lower feed rate (v4) in such a way that the dressing crystals split up the CBN-grains (20) at their tips (Fig. 2).

Abstract: The pyrolitic carbon precursor based on synthetic phenol residues has a softening point of about 100 DEG C (Kraemer-Sarnow) and contains only very small quantities of toxicologically objectionable substances. It pyrolyses smoothly in the range from about 200 to 800 DEG C and thus forms 30 to 40 % by weight of pyrolitic carbon. The low phenol content is achieved by a thermal distillation treatment with addition of high-boiling aromatic oils.

Abstract: A method and apparatus for processing operator assistance calls with minimum expenditure of operator work time. For collect and person-to-person calls, a first operator at a first operator position determines the type of call and, optionally, the name(s) of the calling and called parties. These are recorded in the memory of a program controlled processor system for controlling an operator assistance switching system. The first operator then disconnects from the call while the call is being set up and the called party being alerted. When the called party answers, a second operator position and second operator, having a display of the call information previously recorded, are attached to the call to determine whether a connection between the calling and called parties should be established and, if so, to cause that connection to be so established. Advantageously, no operator position and operator need be attached to the call while the called patty is being alerted; even more operator work time is saved if the called party never answers.
