    摘要: A head for laying optical fibres in a helically grooved cable core consists of a freely rotating mount assembly carrying fibre guides inclined on the axis of travel of the core with an angle smaller than 45.degree.. The fibre guides are elastic hollow tubes ended by a bevel maintained on the bottom of the associated groove. An optical control unit is provided for correct positioning of the mount when starting to lay.

    摘要: The device for supporting a cutting-tool is intended to be placed in a head for machining grooves in a cylindrical rod and mainly comprises a frusto-conical support member having an axial bore through which the cylindrical rod to be machined is capable of passing. The support member is placed within a frusto-conical recess of the machining head and provided with a cutting-tool recess having an opening which defines the profile of the cylindrical rod. The cutting-tool is clamped within its recess by means of a ring which is screwed into the support member and has a control front face for receiving the rod to be machined.

    摘要: A method and apparatus for determining the flow rate and other flow characteristics of a polyphase fluid or a turbulent single-phase fluid flowing in a conduit are disclosed. Two differential pressure sensors are provided, each having two pressure ports sensitive to local pressure variation in the fluid. The pressure ports are maintained in a predetermined spatial relationship and in a predetermined orientation relative to the general direction of the flow. The detection signals from the respective sensors are correlated to obtain the flow rate. Additionally, a selected one of the detection signals is processed to obtain other flow characteristics. One of these other flow characteristics, the type of flow, is useful in facilitating the determination of the flow rate.
