    • A core orientation tool 10 for providing an indication of orientation of a core sample 112 comprises an electronic orientation device 20, which upon receipt of a trigger signal, logs one or more indications of orientation of the tool 10. A trigger system 24 provides trigger signals to the electronic device 20 based one or both of (a) detecting one or more downhole events and (b) the effluxion of time. The downhole events relate to the action of core breaking and may include detecting: uphole motion of the tool; and, cessation of drilling and commencement of drilling.

    • The invention relates to a fluid-transfer device (16), including a rotor comprising two centrifugal wheels (20, 30), and a stator including a set of continuous axisymmetric return channels (50), channelling the fluid from the first wheel to the second wheel (30). Each of the return channels comprises, in series, a diffusing portion (52) which guides the fluid in a centrifugal direction, a bent portion (54) which redirects the flow of fluid in a centripetal direction, a return portion (56) which guides the fluid along a centripetal path, and then an outlet portion (57) formed in a first non-tubular part (62, 162), which guides the fluid towards the second wheel. In said channels, the diffusing portion (52) and the bent portion (54) are separate parts, and the diffusing portion is formed in a second non-tubular part (62, 163) secured to the first non-tubular part. The invention also relates to a method for manufacturing said device.
    • 一种流体输送装置,包括具有两个离心轮的转子,以及定子,其结合有一组连续的轴对称返回通道,将流体从第一轮传送到第二轮。 每个返回通道依次包括在离心方向上引导流体的扩散部分,沿向心方向重定向流体流的弯曲部分,沿向心路径引导流体的返回部分,然后是出口部分 形成在将流体引向第二轮的第一非管状部分中。 在这些通道中,扩散部分和弯曲部分是不同的部分,并且扩散部分形成在固定到第一非管状部分的第二非管状部分中。 一种制造该装置的方法。
