    Abstract: A device for the in-situ extraction of a hydrocarbon-containing substance, while reducing the viscosity thereof, from an underground deposit, has at least one injection pipeline extending in the deposit and at least one production pipeline leading out of the deposit, which together form a so-called well pair. The injection and production pipelines each have a starting region extending above ground in some areas, and an active region connecting to the starting region inside the deposit. With the method, during a heating phase hot steam is applied to the injection and production pipelines, while during a production phase hot steam is applied only to the injection pipeline. Furthermore, the active region of the injection pipeline is additionally configured as an induction heater regarding the surrounding area in the deposit. In the associated device, for example, the well pair formed by the injection pipeline and production pipeline can be configured as electrodes.

    Abstract: In a protective circuit for a converter having a plurality of phases, for each phase current of the phases, a signal proportional to the respective phase current is applied to a transformer circuit that, below and in the area of a limiting frequency, functions as a low-pass filter with the limiting frequency, and above the limiting frequency, functions as a divider. The outputs of the transformer circuit are applied to a maximum generator for forming the absolute value maximum. This maximum is fed to a comparator in which the maximum is compared to a reference value.

    Abstract: A method for error detection in a drive mechanism, having a multiphase electric motor and a converter connected upstream thereof, wherein the converter controls voltages of individual phases of the electric motor, and individual phase currents in the individual phases of the electric motor each extend periodically. The method includes measuring a phase current of the electric motor at a predetermined point of a respective period, simultaneously varying a voltage that is associated with the measured phase current and evaluating a measured value of the measured phase current as a function of the voltage that is associated with the measured phase current.

    Abstract: Disclosed is a ship propulsion system comprising a synchronous machine (6) with an especially superconducting rotor winding that is to be subjected to intense cooling and a normally conducting stator winding (11) which is to be cooled. The stator winding (11) is disposed at least in part inside a support structure (14) encompassing a hollow cylindrical magnetically soft outer body (13) and web-type support teeth (21i) that extend in an axial and radial direction. A hollow cylindrical part (15a) of an exterior housing (15) encloses the outer body (13). In order to cool at least some areas of said housing part (15a), the stator winding (11) is thermally coupled to water as a cooling medium (K) via the support structure (14) and the housing part (15a).
