    摘要: A process for the continuous preparation of an aqueous solution of a salt of an alkanedicarboxylic acid of 6 to 12 carbon atoms and an alkanediamine of 6 to 12 carbon atoms by reacting the particular alkanedicarboxylic acid with the particular alkanediamine in an aqueous solution of the salt to be prepared. The aqueous salt solution is recycled from a first mixing zone via a transport zone and a second mixing zone into the first mixing zone, liquid alkanediamine and an aqueous solution of alkanedicarboxylic acid are introduced between the first and second mixing zones. Less than the equivalent amount of alkanediamine is introduced, the remaining amount of liquid alkanediamine is added after the second mixing zone, and aqueous salt solution is taken off the first mixing zone at the rate at which it is formed. The salt prepared is used for the manufacture of a nylon.

    摘要: A process for the manufacture of nylons by heating an aqueous solution of a salt of an alkanedicarboxylic acid of 6 to 12 carbon atoms and a diamine of the formula NH.sub.2 RNH.sub.2, where R is alkylene of 6 to 12 carbon atoms or is a radical ##STR1## to a temperature at which a nylon is formed, under superatmospheric pressure and with removal of water. The solution used is an aqueous solution of from 75 to 90 percent strength by weight of a salt of a dicarboxylic acid and a diamine, which solution has been obtained by neutralizing a less concentrated salt solution, which contains an appropriate dissolved excess of the particular dicarboxylic acid, with the corresponding diamine. The nylons obtained are used for the manufacture of moldings.

    摘要: According to the invention, a controlled or synchronous switching of an electrical power breaker (1) can be guaranteed by means of predicting a future voltage and/or current curve from actual voltage and/or current data in an electrical energy network (5). The prediction of the future voltage and/or current curve is carried out using the voltage and/or current data determined in the electrical network (5) at different timepoints by application of a Prony method to the available voltage and/or current data.

    摘要: A method and a device for determining a switching time of an electric switching device. An electric switching device includes an interrupter link. A first line section and a second line section can be connected and disconnected by way of the interrupter link. In order to determine a switching time, the temporal progression of a driving voltage is determined in the first line section. In addition, a temporal course of an oscillator voltage appearing in the second line section is determined. Potential switching times are determined at the voltage zero crossings of a resulting voltage. The selection of the potential switching times ensues while evaluating the rises of the driving voltage and of the oscillator voltage or of the polarity of the oscillating current.
