    摘要: The invention pertains to new catalyst systems for polycondensation reactions, for example for producing polyethylene terephthalate. In accordance with the invention, complex compounds with hydrotalcite-analogous structures of general formula [M(II)1−xM(III)x(OH)2]x+(An−x/n).mH2O are used, wherein M(II) represents divalent metals, preferably Mg or Zn or NI or Cu or Fe(II) or Co, and M(III) represents trivalent metals, for example Al or Fe(III), and A represents anions, preferably carbonates or borates. These catalysts can be calcinated and can be used in combination with phosphorus compounds that contain at least one hydrolyzable phosphorus-oxygen bond.

    摘要: A method of producing similar deep-drawn parts for double-walled structural parts having uniformly spaced walls and edge welding. During every deep-drawing procedure, a respective planar outer plate, which is placed upon the lower part of the tool, as is a filler plate, as well as a preformed or preshaped inner plate, which is placed over the tool punch, are shaped in common, whereby the preformed inner plate and the outer plate receive their final form or shape, and the filler plate is deformed into a preshaped inner plate for a subsequent deep-drawing procedure. The tool for carrying out this method is characterized in that the smallest spacing between the tool punch and the lower part of the tool corresponds to the entire thickness of the two inner plates and one outer plate.

    摘要: The invention relates to an electrical machine (10), especially a three-phase generator for vehicles. The electrical machine (10) comprises a stator (16) and a rotor (20). The rotor (20) comprises a first and a second claw pole (22, 23) from which claw pole fingers (24) respectively extend in the axial direction from claw pole roots (60). A centring point (74) for a tool is located on a rear radius (72) of the claw pole roots (60).
