    Abstract: Système (1) de mesure de conductivité électronique d'une bande (2) d'électrode défilant entre un premier et un deuxième rouleau (3, 4) rotatif, ce système comprenant
    - un dispositif (11) de mesure de conductivité électronique ;
    - un premier élément conducteur (12) de contact mobile en rotation connecté audit dispositif, ce premier élément conducteur de contact intégrant un premier bord distal circulaire destiné à venir en contact tangentiel avec une première surface de la bande d'électrode ;
    - un deuxième élément conducteur (13) de contact mobile en rotation connecté audit dispositif de mesure, ce deuxième élément conducteur de contact intégrant un deuxième bord distal circulaire destiné à venir en contact tangentiel avec la première surface lorsque le premier bord distal circulaire est en contact avec ladite première surface de sorte à pouvoir appliquer un courant électrique prédéfini entre le premier et le deuxième élément conducteur (12, 13).de contact

    Abstract: The present invention relates to a sampler for taking samples from a molten metal bath, particularly a molten steel bath, the sampler comprising:
    a carrier tube having an immersion end;
    a sample chamber assembly arranged on the immersion end of the carrier tube, the sample chamber assembly comprising a cover plate and a housing, wherein the housing comprises an immersion end having an opening;
    an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, wherein the opening is configured to receive the molten metal from the inflow conduit;
    a measuring head, wherein the sample chamber and the second end of the inflow conduit are at least partly arranged in the measuring head; and
    a de-oxidant material arranged along a central axis of the inflow conduit, wherein at least part of the de-oxidant material is arranged near the second end of the inflow conduit inside the measuring head, and wherein the inflow conduit comprises first coupling means, arranged on the second end of the inflow conduit, wherein the de-oxidant material comprises second coupling means, to interact with the first coupling means on the inflow conduit to anchor the de-oxidant material in a position along the central axis of the inflow conduit. The invention also relates to a sampler for taking samples from a molten metal bath, particularly a molten steel bath, the sampler comprising:
    a carrier tube having an immersion end;
    a sample chamber assembly arranged on the immersion end of the carrier tube, the sample chamber assembly comprising a cover plate and a housing, wherein the housing comprises an immersion end having an opening;
    an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, wherein the opening is configured to receive the molten metal from the inflow conduit;
    a measuring head, wherein the sample chamber and the second end of the inflow conduit are at least partly arranged in the measuring head; and
    a metal bushing, wherein the metal bushing coupling the inflow conduit to the sample chamber.

    Abstract: A system for verifying authenticity of precious metal coins and bars includes a sensor system defining a sample region configured to receive a precious metal coin or bar therein; a sample support; and a data processor configured to communicate with the sensor system so as to receive a detection signal therefrom and to provide an output signal. The system includes a data storage device and an output display. The sensor system detects a bulk electrical property of the coin or bar. The data processor processes the detection signal and retrieves a stored physical property from the data storage device to provide an output signal that includes at least a measured value of the bulk electrical property and a corresponding range of expected values. The output display uses the output signal to display information for a user to be able to make an authenticity verification of the coin or bar.
