摘要:
A device suitable for the qualitative characterisation of the state of a surface. The invention concerns a device suitable for the qualitative characterisation of the state of a surface of an object, for example for the qualitative characterisation of a surface of a piece of wood, comprising: • a feeler (10), • a means for rotating the feeler, such that the feeler follows a circular trajectory, • an electroacoustic transducer (30), configured to produce an electrical signal representative of the sound waves transmitted by the feeler. Application to the qualitative characterisation of a surface, for example at the end of a production line producing parts. Application to all types of materials: woods, metals, plastics, fabrics, etc.

An object of the present disclosure is to provide a process for the preparation of a sulfur-molybdenum cluster composition, the process comprises for example: preparing a precursor comprising a first molybdenum compound, coating of a substrate with the precursor, calcinating the precursor, sulfurizing the precursor, and reducing the precursor in presence of a second molybdenum compound and of a reducing agent.
摘要:
Method of stabilizing a DC electric network, this network comprising a DC voltage source (11) powering electric loads (12,18, 24) which are connected in parallel across the terminals of the voltage source (11) and which are each intended to receive a setpoint of the current or the power, characterized in that the network is stabilized by regulating the setpoints applied to the loads (12,18, 24) by means of a virtual stabilization impedance generated across the terminals of each load (12,18, 24), these virtual impedances being dimensioned so as to stabilize the network in various desired operating points and in various given configurations of the network comprising the state where at least one load is inactive or faulty and the state where the stabilization of a load is inactive, each virtual impedance being generated by means of a nonlinear regulating loop acting on the setpoint of the corresponding load.

The present invention describes novel biomaterial fillers containing cross-linked sodium alginate and the method for manufacturing same, for use in the medical field and intended, in particular, for filling tissue lesions having a layered structure of varying compositions, such as cartilage, skin or the epithelium. These novel biomaterials have the special feature of being multiphasic, composite and functionalized, for medical use and, in particular, for treating tissue lesions having a layered structure of varying compositions. Said biomaterials are particularly suitable for treating focal lesions of the articular cartilage.
摘要:
The present invention relates to an anticorrosion composition for the "metals" consisting of or comprising at least one saponification product of at least one plant oil, or mixture of plant oils, the plant oil or oils comprising "C14-C22" carbon atom chains, a process for manufacturing, in a single reactor ("one-pot" process) a saponified plant oil composition, products and compositions resulting from this process and the uses thereof.
摘要:
The invention relates to a heating unit adapted to perform a method including a steam condensation step. The unit comprises an evaporation device designed to evaporate a fluid and a device for condensing steam leaving the evaporation device, said condensation device including a steam collection tube having one end connected to a steam outlet of the evaporation device. The unit is characterised in that the condensation device also comprises: a thermoelectric device (10, 11, 15) including a through-hole in which the collection tube is positioned, an internal surface of the hole forming a cold surface of the thermoelectric device; and a control module (47) for supplying the thermoelectric device with an electric current according to the condensation temperature of the steam passing through the collection tube. The invention is suitable for condensing steam.

The disclosure notably relates to a Nuclear Quadrupole Resonance (NQR) spectrometer comprising a System on Chip (SoC) Field Programmable Gate Arrays (FPGA) (240) communicatively coupled to an external memory (320). The SoC FPGA (240) is configured to perform the function of a pulse programmer (250) for producing pulse sequences. The pulse programmer is configured for reading, sequentially, instructions stored on the external memory. The SoC FPGA (240) is further configured to perform the function of an acquisition module (260) for processing an acquired analog response signal (FID) emitted by nuclei of a material to be studied and for recording the processed signal on the external memory. The NQR spectrometer offers improved portability, usability and sensitivity with respect to the state of the art.
