    摘要： A pipeline system (100) comprises:
    a pipeline portion (101),
    at least one sensor (110) on the pipeline portion (101) for measuring a physical property of the pipeline portion (101) or of a fluid inside the pipeline portion (101), and
    an electromagnetic field source (120) distributed along the pipeline portion (101),
    the sensor including an accumulator for storing an electric charge induced in the accumulator when the sensor is subject to the electromagnetic field created by the electromagnetic field source, the accumulator being able to power the sensor by means of the stored electric charge.

    摘要： A downhole fluid flow control system is operable to be positioned in a wellbore in a fluid flow path between a formation and an internal passageway of a tubular. The system includes a flow control component positioned in the fluid flow path that is operable to control fluid flow therethrough. The system also includes a pressure sensitive valve positioned in the fluid flow path in parallel with the flow control component. The valve autonomously shifts from a first position to a second position responsive to a change in a pressure signal received by the valve, thereby enabling fluid flow therethrough.

    摘要： Die erfindungsgemässe Bohrvorrichtung 1 weist eine Spülvorrichtung zum Spülen einer Bohrung 5 mit einem Spülfluid 7 auf. Eine hydraulisch angetriebene Vortriebseinrichtung 21 ist vorgesehen einen Bohrer 2 in der Bohrung 5 vorzutreiben. Ein Durchflussbegrenzer 30 ist in Hydraulikleitungen 25 der Vortriebseinrichtung 21 angeordnet, um die Vortriebsgeschwindigkeit einzustellen. Der Durchflussbegrenzer 30 weist ein durch Druck betätigbaren Stellelement 38 zum Einstellen einer Durchflussbegrenzung auf. Eine pneumatische, hydraulische und/oder mechanische Kopplung 39 überträgt den Druck des Fluids 7 auf das Stellelement 38.
