    摘要: The invention relates to novel zinc/metal hexacyanocobaltate complex compounds corresponding to the formula:Zn.sub.3-v M.sub.v [Co(CN).sub.6 ].sub.2.w(H.sub.2 O).x(L).y[Zn(X).sub.n ].z[M(Y).sub.m)].These complex compounds are suitable catalysts. This invention also relates to a process for the production of the compounds, and to the use of the compounds in a process for the production of polyether polyols.These novel zinc/metal hexacyanocobaltate complex compounds when used as catalysts in a process for the production of polyether polyols substantially reduce the induction period of the polyaddition reaction of alkylene oxides to starter compounds containing hydrogen atoms. Furthermore, the resultant polyether polyols have a significantly narrower molecular weight distribution.

    摘要: Polyether polyols are produced by acid-catalyzed polyaddition of alkylene oxides to starter compounds having active hydrogen atoms. Perfluoroalkylsulfonic acid salts of metals from Group IIIA of the Periodic Table of Elements (corresponding to the IUPAC Convention of 1970) are used as the catalyst. The polyaddition reaction is carried out at a temperature of from 40 to 200.degree. C. at normal pressure or pressures from 0 to 20 mbar (absolute). An inert organic solvent may optionally be included in the reaction mixture. Substantially all of the catalyst is removed from the polyether polyol-containing reaction mixture by lowering the temperature and/or by addition of a precipitating agent and/or by extraction with water. If desired, the recovered catalyst may be used in subsequent polyaddition reactions.

    摘要: The invention relates to a method of welding weld studs to a workpiece, in particular of aluminum in each case, by the stroke ignition method, in which the stroke height(s) of the weld stud (1) is altered as a function of the measured arc voltage and optionally of the arc firing time. In particular, the stroke height(s) of the stud (1) can be increased during the occurrence of short circuits, i.e. during a sudden drop in the arc voltage, preferably in predetermined steps. The weld stud is immersed into a pool of melt after a predetermined period of time of between 5 and 10 ms after the welding current has been switched off. The polarity of the stud or of the workpiece is changed at least once during the welding process. The welding current is interrupted for a predetermined period of time for this purpose. The method leads to an improved, readily reproducible quality of weld.

    摘要: An ordering means for document files or the like comprises a base plate which is provided with at least two fixed ordering pins. At least one movable closure bow can be brought into closure contact with the ordering pins. Possibly a holder-down is provided which is adapted to be clamped with respect to the ordering pins. A locking member displaceable with respect to the base plate serves to adjust the closure bow or bows and on the base plate guide means are provided for guiding the locking member. The locking member is provided with guide slots or guide grooves via which the locking member is in engagement with each closure bow so that on displacement of the locking member the respective closure bow can be opened or closed.

    摘要: The invention relates to a quick set-up system for calibration devices located downstream from an extruder, in particular one for synthetic profiles. With this quick set-up system, a dry gauge and the vacuum tank(s) are mounted on two horizontally positioned tubes that are positively connected to the calibration stage, such that they can be moved and adjusted horizontally and vertically, which enables an exact advance adjustment of the gliding device, and with it, of the vacuum tanks and calibration device, thus eliminating a subsequent alignment. In addition, by installing a central water disposal system, the required replacement of hoses with different lengths when moving the vacuum tanks is avoided.
