Abstract: Polycarbonate can be obtained using a multistep continuous phase boundary process, a special pump reactor and a tubular reactor, special reaction conditions, and a specific ratio of metered starting components to the amount of reaction emulsion remaining in the pump reactor. Polycarbonate can be obtained using a multistep continuous phase boundary process, a special pump reactor and a tubular reactor, special reaction conditions, and a specific ratio of metered starting components to the amount of reaction emulsion remaining in the pump reactor. The method includes the following steps: (A) continuous mixing of an organic and aqueous phase in a specially designed pump reactor, where the organic phase is a solvent for the polycarbonate, contains phosgene, and the aqueous phase consists of a mixture of alkali hydroxide and phenolic components (bisphenol A and optionally monophenol as chain splitter); (B) by means of a heat exchanger, a mean temperature of less than 60 degrees C is established in the pump reactor, and part of the emulsion obtained over a period of 2 minutes is removed continuously from the reactor via an intermediate vessel (IV); (C) the emulsion portion is pumped through tubular reactors provided with mixing dwell zones, providing 2 and 40 minute dwell times, where: (1) the ratio (in moles per mole) of the metered amount of phosgene to the theoretical amount required to react all the phenol and bisphenol is 1:12 to 1:22; (2) the phosgene and bisphenol solutions in the pump reactor are metered directly downstream of (IV) into the pump circuit, and the chain splitter is fed into the pump circuit or optionally directly into the tubular reactors; (3) alkali hydroxide is metered into the pump reactor on the pump suction side in amount 15-40% of the total amount to be metered; (4) inside the pump reactor in the pump circuit in accordance with (2) above bisphenol A and phosgene are metered so that the ratio of their total amounts measured as the throughput over the pump circuit cross section (the sum of both solutions measured in cubic meters per hour) to the pumped emulsion is 1:3 to 1:12, and the amount fed to the IV corresponds to the total amount of metered solutions (sic); (5) immediately before feeding to the tubular reactor, more alkali solution (85-60% of the total metered alkali solution) is fed into the amount removed from (IV), and if required a chain splitter is added; and (6) after a further 1-20 minutes dwell time in the tubular reactor a catalyst is added to this reactor.

Abstract: The method determines the distance of an object from a measurement device with a transmitter, receiver and filter with a fixed phase characteristic. A light signal is transmitted towards the object, with the reflected signal received by the receiver. The output of the receiver is connected to the transmitters so that an oscillation circuit is formed. The resonance frequency of the circuit is measured and used to determine the separation distance. The invention also relates to a corresponding device. The resonance frequency of the oscillation circuit is determined for at least two phase characteristics.

To provide for reliable evaluation of the individual system leakage variables, namely the resistive and capacitive system leakage variables in any power systems, even those with low-frequency faults, it is proposed, in accordance with the invention,   a) that at least two constant-amplitude period alternating measuring signal voltages or at least two constant-amplitude periodic alternating measuring signal currents are injected as measuring signals which exhibit measuring signal frequencies (f1, f2) which are as low as possible and are within a range largely free of interference signals and differ from one another and from the power system frequency (fN), b) that an absolute-value quotient (K1 and, respectively, K2) is determined for each of the different measuring signal frequencies, in connection with which   b1) in the case of alternating measuring signal voltages to be injected, these are injected into the power system via a resistor-type power system coupler and in which case in each case the absolute-value quotient between the voltage amplitude - or a quantity derived therefrom - of the fundamental or of an harmonic of the alternating measuring signal voltage and the voltage amplitude - or a quantity derived therefrom - occurring across the resistor-type power system coupler - of the associated fundamental or harmonic of the output signal is measured, whilst b2) in the case of alternating measuring signal currents to be injected, these are injected directly into the power system without resistor-type power system coupling and in which case in each case the absolute-value quotient between the current amplitude - or a quantity derived therefrom - of the fundamental or of an harmonic of the alternating measuring signal current and the voltage amplitude - or a quantity derived therefrom - occurring between power system and earth of the associated fundamental or harmonic of the output signal is measured,   c) and that the two system leakage quantities (RE, CE) are determined from fixed functional relationships which in each case depend on the two measuring signal frequencies (f1, f2) and the two absolute-value quotients (K1, K2).   <IMAGE>
