Abstract: A method for manufacturing a composite filament aimed to an additive manufacturing application or a winding application, the method comprising, in the following order: providing a thread of fibers; impregnating the thread with a liquid reactive thermoplastic resin; co-extruding a sheath of thermoplastic material around the impregnated thread; and curing the thermoplastic resin. Additionally, a filament obtained at least partly by the method, the use of the filament for manufacturing a product obtained by an additive manufacturing or by a winding technique, and a machine for performing the method, thereby enabling a high-speed production (e.g., 10 meters per minute) of a filament of high quality.

Abstract: A method for processing mass spectral data that has, for example, been obtained using a mass spectrometry device comprising deflection beams for scanning an ion beam over an area spanning the vertical direction of a microchannel plate focal plane detector, in order to increase the count rate of the detector. The method allows to efficiently combine ion counts that are detected on different areas of the focal plane detector, as a result of different deflection voltages being applied to the corresponding ion beams. Even though such beams also suffer unwanted deflections along the horizontal axis of the focal plane detector, the present method allows to re-align ion counts efficiently and to register them with accurate mass-to-charge ratios, which results in increased mass resolution power of the resulting combined mass spectrum.

Abstract: A thermal management system comprising: a thermal source of low to cryogenic temperature; a heating element for heating the source; a shield adapted to exchange heat by conduction to/from a sample and to/from the source; a controller calibrated for maintaining a gradient of temperature along the shield within a pre-determined range; a vacuum sealing feedthrough comprising a thermal insulator element, the vacuum sealing feedthrough delimiting around the first interface a vacuum sealed volume so that the shield exchanges heat with the thermal source exclusively by conduction and exclusively at a first interface. An exemplary purpose for this thermal management system is the sublimation of water ice and/or water ice trapped in a regolith, and positioned in a vacuum chamber. The heat insulator element is configured to separate physically the thermal source from a vacuum chamber into which the shield can protrude, so that sublimated compounds from the sample do not encounter colder point which would cause their deposition on the shield or on the walls of the chamber.

Abstract: A post-discharge plasma coating device for a wired substrate comprising an inner tubular electrode on an inner tubular wall for receiving the substrate and a precursor moving axially in a working direction; an outer tubular electrode coaxial with, and surrounding, the inner tubular electrode. The inner and outer electrodes are configured to be supplied with an electrical power source for producing a plasma when a plasma gas is supplied between the electrodes and is thereby excited, the plasma excited gas flowing axially in the working direction and reacting with the precursor in a coating area at the end of the inner tubular wall in the direction. The inner tubular wall extends axially towards the coating area at least until, in various instances beyond, the end of the outer electrode, in the working direction and at least one dielectric tubular wall extends axially between the inner tubular electrode and the outer tubular electrode.

Abstract: A system for incubating one or more cells and/or organotypic cultures for biological investigation, in particular for toxicology assessment, comprising a bio-incubator and a pressure system fluidly connected with the bio-incubator. The pressure system is a cyclic gas pressure system configured for cyclically varying the gas pressure in the bio-incubator between a negative pressure and a positive pressure compared to the atmospheric pressure, so as to reproduce the pressure conditions in lungs of a living mammal. The system is remarkable in that the cyclic gas pressure system comprises a feedthrough with a pipe configured to deviate the air influx from the one or more cells and/or organotypic cultures.
