  • Publication number: 20110156833
    Abstract: A network filter for connecting a converter to a 3-phase supply network includes in each phase a toroidal inductor which is connected in series with a commutation inductor at a respective first connection point, and a capacitor circuit having at least four capacitances, wherein first terminals of a first, a second and a third capacitance is connected in one-to-one correspondence to a respective one of the first connection points. Second terminals of the first, second and third capacitance are connected at a common second connection point, with a fourth capacitance being connected between ground and the common second connection point. The windings of the toroidal inductors can be formed of the connecting lines which connect the corresponding first terminals to the three phases of the supply network.

  • Publication number: 20100132451
    Abstract: The invention relates to a method for determining an amount during the transfer of a liquid, wherein the liquid is introduced at a supply opening into a measurement line and is removed from the measurement line at an outlet opening, and an amount of liquid flowing through the measurement line is determined by means of a flow measuring unit assigned to the measurement line. According to the invention, liquid present in the measurement line is discontinuously fed to a degassing arrangement. The invention further relates to a device for determining an amount during the transfer of a liquid.

  • Patent number: 6347723
    Abstract: The invention relates to a security system for flowable products in storage and/or transportation tanks, which have openings at least for filling, removing and/or controlling purposes. The security system comprises a control device and write-read devices for data exchange with connection elements connectable to the openings. The connection elements have a code mark or a tag. With each opening is clearly associated a tag. With each opening is also associated a closure element as a connection element, on which is located the tag associated with the opening. The associations of tag and opening are controllable and storable in the control device and in the case of a specific association of all the tags with the particular openings a manipulation-free state can be displayed by the control device.

  • Patent number: 5503026
    Abstract: In a process for the determine ton of a volume flow a fluid is passed through a measuring line with a defined cross-section. In the measuring line the flow rate and the fill degree of the measuring line are determined and the volume flow is determined from the flow rate, the measuring line cross-section and fill degree. The determination of the flow rate and the fill degree takes place with a single measuring chamber at the same time and at the same location with respect to the axial extension of the measuring line.

  • Patent number: 5320733
    Abstract: The invention relates to a sensor system for determining the moisture content in a gas to be measured. On the basis of two current saturation ranges during the determination of the moisture content with the aid of a zirconia sensor, according to the invention two spatially separated sensors are provided, which are operated at different voltages corresponding to the individual saturation current ranges. By further evaluation of the signals, this permits a very precise, on-line determination of the moisture content of the gas to be measured.

  • Patent number: 5258603
    Abstract: The invention concerns a reading head with a tapered reading opening and/or a tapered reading stylus for reading bar-type, especially passive magnetic information on a data carrier. A high resolution in reading this information with a high output signal is obtained by tapering the reading opening in direction of the end face of the reading head. The reading head is located in a casing pot and has at least one field plate sensor, on which side remote from the face a permanent magnet is placed with a magnetic shunt to the casing pot.

  • Patent number: 4941240
    Abstract: Beam warping machine with a device for the maintenance of required yarn tension in a group of yarns (5) with rolls (7, 8; 34, 35, 36) around which said group of yarns is wound following an S-shaped path in continuous operation, said pair of rolls being driven without slippage in a operative position (51), whereby brakes (30) acting upon the warp beam (3) are activated when the machine is stopped while at the same time one of the rolls (7,35) is swivelled radially out of its operative position (51) and away from the yarn group (5), whereby the swivelling motion ends in a slippage position (37) which can be selectively adjusted as to degree of swivelling by means of an adjustment link (39), whereby the yarns in the area of the rolls (7, 8; 34, 35,36) braked with the displacement assumes a path allowing for slippage of the yarn group (5) against the rolls (7, 8; 35, 36), said path being straighter than the S-shape.

  • Patent number: 4736602
    Abstract: This invention relates to a warp knitting machine in which the knitting elements and each of the warp beams are driven by separate electric motors, powered from a common electrical network. An electric clutch is included in the drive connection between each warp beam and its electric motor and said clutch is energized by the same electric network which powers the electric motors. The electric clutch is energized when electric current is supplied to it by the network and connects the warp beams with their own electric motors. Whenever the electric current in the network is interrupted, the electric clutch is disengaged.
