Abstract: Data are transmitted from a secondary station to a master station along a segmented path, wherein two contiguous segments are respectively connected by a node and wherein the path has at least three segments with at least two nodes. The data from the secondary station are split into N data packets, where N is the number of nodes. The data packets are marked distinguishably, each marking corresponding to a particular node on the path. Each data packet along the path is forwarded only to the adjacent node or adjacent station. Each node checks to determine whether the marking of the packet corresponds to the respective node. If so, data from the node are added to the data packet. The data packets are collected in the master station. The data transmission is concluded successfully if all N data packets with data from all N nodes are present.

Abstract: The invention relates to a method of continuous non-destructive examination of specimens by so-called radio-synthesis, which can be integrated into the process for managing the life cycle of said specimens. This method operates by means of at least one X-ray source and of at least one digital sensor forming a pair with said source, source and sensor moving along opposite and homothetic trajectories inside a motion space, for each real-time generation of at least one cross section of each specimen.

Abstract: A method and apparatus for manufacturing a graded-index plastics optical fiber of continuously varying index profile, starting from a particular polymer P and a particular compound M1, the method including the steps of: preparing two compositions of different refractive index, allowing the compositions to diffuse one into the other, and spinning the compositions so as to obtain the fiber, wherein, prior to extrusion, the two compositions are subjected to active mixing, and extrusion of the fiber is followed by curing.

Abstract: A process and device for continuously measuring the quantity of particles spended in a liquid, which exist in at least two different physical states, such as detached or attached within the paper pulp. A separation assembly separates the particles into divisions depending on their size, and the separation assembly is continuously fed with liquid via an input pipe. A measuring and processing assembly has two channels or ducts coming from the separation assembly and are provided with translucent windows. A measurement and capture unit illuminates the windows, and at least two cameras located opposite each of the respective windows are synchronized with the illumination unit to capture, at regular intervals, an image of the windows. A system for digitizing the captured images and processing them to determine the quantity of particles for each physical states is forwarded to an output unit in a digital or analog form.

Abstract: The flexible bearing is formed of a sleeve-shaped smooth bearing 6 fixed in a flexible block 4 nested in a housing 3 of the boat so as to absorb the bending deformations of the mainpiece without transmitting them to the structure. The housing 3 is streamlined so as to block the flexible block.

Abstract: A process for fractionating a suspension of solid particles in a liquid, of he type wherein said suspension is made to pass through a filtering screen, characterized in that said suspension is directed in a direction parallel to the longitudinal axis of an elastically deforming, flexible, perforated sleeve forming a filtering screen, and in that a sequence of high and low pressures is continuously created within this sleeve and travels at least predominantly opposite the direction of the suspension flow. The invention also applies to equipment.
