  • Publication number: 20140202544
    Abstract: A fitting for changing liquid paths, in particular for systems with a pressure exchanger, is provided. The pressure exchanger has pipes having alternating flow direction. The casing of the fitting includes an inlet piece, an outlet piece and a connection piece and at least one shut-off member connected to an actuator. The actuator is connected to a control device that controls the actuator to control a liquid flow between the inlet piece and the connection piece, or between the connection piece and the outlet piece. An actuator displaces a respective shut-off member arranged in each of the inlet piece and the outlet piece, with the shut-off members being axially displaceable to vary the size of flow openings that permit flow between the inlet piece and the connection piece or between the connection piece and the outlet piece.

  • Publication number: 20090116506
    Abstract: According to the invention, connection information (vcxIndex) representing each connection (AE1 . . . n) of the at least one communication device (KE1 . . . n) to a multiplexer device (MUX) is stored in the multiplexer device, the connection information (vcxIndex) is allocated to the at least one communication network specific address (IP) of the at least one communication device (KE1 . . . n) connected to the connector (AE1 . . . n). A message (ARP-REQUEST) sent to the multiplexer device (MUX) is detected and at least one target address (ZA) contained therein is compared with the stored communication network specific addresses (IP). On determination of an at least partial match of the compared pieces of information (IP, ZA) the message (ARP-REQUEST) or information or initiating the communication relationship device is forwarded to the at least one connector (AE1 . . . n) represented by the allocated connector information (vcxIndex).

  • 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.
