  • Patent number: 7501084
    Abstract: The invention relates to a method for producing fabric-reinforced capillary membranes, particularly for ultrafiltration, in which a fabric tube (1) is coated with a polymer solution and is guided through a precipitation bath (6), where the polymer solution is converted into a microporous layer in the precipitation bath (6), and a membrane that is reinforced by the fabric tube is formed. According to the invention, the fabric tube coated with the polymer solution passes through the precipitation bath (6) from top to bottom, without mechanical contact, and exits through a nozzle (7) at the bottom. Liquid flows out of the nozzle (7), which liquid exerts a tensile force stabilizing the course of the coated fabric tube, on the capillary membrane (8) leaving the precipitation bath.

  • Patent number: 7358716
    Abstract: A measuring method for measuring currents with a large dynamic range by means of a magnetic measuring module has the steps of switching into a high-current mode when a current threshold value is exceeded, and switching into a low-current mode otherwise, wherein the low-current mode has the following steps:—Feeding a first current pulse to a compensation coil, which drives a magnetic core in a first direction until magnetic saturation occurs,—measuring a first primary current value I1 after the current pulse is disconnected,—feeding a second current pulse to the compensation coil, which drives the magnetic core in a counter second direction until magnetic saturation occurs,—measuring a second primary current value I2 after the second current pulse is disconnected,—determining the corrected primary current value subsequently as an average value I=(I1+I2)/2 from the first and the second primary current values.

  • Patent number: 7057485
    Abstract: Addressed is a current transformer comprising a primary conductor, a secondary winding and a soft-magnetic core, whereby the primary conductor and secondary winding are electrically insulated from one another and are magnetically intercoupled via the core. In addition, a current to be detected is injected into the primary conductor, and a compensating current is injected into the secondary winding. An additional conductor is provided which is electrically connected in parallel to the primary winding, and which is situated in the area of the core at which a flux rise occurs, whereby the flux rise is at least partially compensated for by the flux elicited by the current flowing in the additional conductor.

  • Patent number: 6449544
    Abstract: In the restraint system, a central control unit and a plurality of data processing units are coupled to a bus line, each of the data processing units being provided to activate one or more restraint devices. In order to keep the restraint system operational to the extent possible in the event of a short circuit, each data processing unit measures for short circuits on the bus line and starts timing if a short circuit is detected. Each data processing unit has a circuit breaker, with which the bus line can be closed or interrupted. This circuit breaker is opened if the short circuit measured is longer than a preset waiting time.
