Abstract: Method and device for extraction of markers, including: introducing a sample into a removable support basket placed in the housing of a cell of an extraction device provided with a flexible membrane and immersing the tissue sample in a liquid previously introduced into the housing, followed by hermetic closing of the extraction cell and application of a pressure cycle on the flexible membrane for a period of 1 to 5 minutes at a frequency between 1 and 2 Hz. Then, total or partial recovery of the liquid immersing the sample after the pressure cycle and detection of the markers present in the liquid.

Abstract: A device for the continuous production of a solid form, including: an extruder for mixing and hot-melting at least one component with at least one polymer for an amorphous solution; and a cutting device mounted downstream of the extruder, for cutting the semi-solid bead that results from the melting of the mixture of the component with the polymer for an amorphous solid solution, the cutting device being combined with a forming system for forming the solid form supplied by the cutting device.

Abstract: The present invention is related to a method for the authentication of an article comprising the steps of generating identification data about an article, geometrical coding the identification data to form one geometric coding, incorporating the geometrical coding into a random pattern to forman authentication pattern, and embedding physically the authentication pattern onto the surface of the article to create a specific roughness.
