    摘要: The invention relates to a device for centring and clamping conduits which are preferably made from alloy steel and which are positioned end to end in order to be welded to form a pipeline. The invention comprises: means for centring and clamping two conduits that are to be welded, optional leak-tight partition means which define an inerting chamber at the mating surface, and inert gas distribution means for creating a protective atmosphere at the mating surface. The inventive device also comprises at least means for regulating the flow of inert gas and/or the supply pressure of said inert gas as a function of the concentration of O2 measured in the protective atmosphere and/or the pressure measured within said atmosphere, such as to maintain the O2 content of the atmosphere below a pre-determined alarm threshold value and/or the pressure of the atmosphere below a pre-determined threshold value.

    摘要: For displaying a selected zone of images belonging to a sequence of video images, each in the form of a matrix of pixels, on a display unit, a signal is generated by a fixed large-field camera having a definition that is greater than that of the display unit. A TV user or an operator at a control station selects a zone of format corresponding to that of the display unit in a field of view of the camera. The pixels of a modified image having the size and definition of the display unit are generated by interpolation from the pixels in the selected zone of the image supplied by the large-field camera. A device for implementing the method includes a module for warping the selected zone by operations of interpolation and resampling.
