  • Patent number: 7888952
    Abstract: A circuit arrangement is provided for balancing a resistance circuit, which has a field-effect transistor as a controllable resistor and a control circuit, by which the field-effect transistor can be controlled with a gate-source voltage so that there is a resistance between a drain electrode and a source electrode of the field-effect transistor in a predefinable ratio to a reference resistor. In a balancing operation mode, a reference current can be set by the drain-source path of the field-effect transistor and by the reference resistor, which depends on a differential voltage between a voltage drop, caused by the reference current at the reference resistor and a voltage drop, caused by the reference current, at the drain-source path of the field-effect transistor.

  • Patent number: 7040174
    Abstract: The pressure cell device according to the invention serves for measuring hydraulic pressures in hydraulic mining devices in an inherently secure service region. It is provided with a connection element which can be connected to a pressure reception connection and with a sensor housing, on the inside of which is arranged a hydroelectric pressure transducer which is pressurised by the hydraulic pressure present at the pressure reception connection and converts this into an electrical signal. So as to ensure high measurement accuracy over a long operating period, without it being necessary to have exchanges of the pressure transducer or its new calibration, it is provided according to the invention that the pressure transducer comprises a ceramic pressure measuring cell.

  • Publication number: 20040033710
    Abstract: For an explosion-proof connection of two electric line ends (25, 26), the contact elements (27, 28) are accommodated in two tubes (1, 2), which can be joined in an explosion-proof manner. Each of the plug-in contact parts is axially secured in its tube by a radial projection (41) in the direction toward the end facing the other tube. At its line end, each of the tubes is closed by an end cap (42), which sealingly surrounds with a narrow outlet (44) the electric lines, including an insulation (43). The tube, in which the plug-in contact part with the contact pins is axially secured, extends beyond the tip of the contact pins, and has there an enlarged diameter, with which it surrounds the other tube (inner tube 1,3) with a narrow cylindrical gap (sealing gap 20).

  • Patent number: 6607403
    Abstract: The invention relates to a plug-in cable connector 3 for electrical cable or plug connections 10. The cable connector 3, which forms the termination of the cable 1, has a hollow connector shell 4 of brass, whose boring forms a cable entry opening on its cable side section and an abutment collar 5 on which a plug connector 6 with a collar 6′ is supported axially in one direction. The cable entry opening is provided with an internal thread 22, in which a four cornered part 30 of metal, having a through boring 35 for the cable, is screwed in. The screening or armouring of the cable 1 can be accepted between the through boring 25 and the cable covering 1′, so that a good earthing of the cable 1 and the cable connector 3 can be achieved. The interior space of the connector shell 4 is sealed by means of a formed part 27, which is formed onto the cable covering 1′, the connector shell 4 and the multi-cornered part 30.
