Abstract: The invention relates to a process and device for polymerizing lactams in molds wherein the monomer, catalyst and initiator are independently fed to a mixing head feeding a mold. The system in turn comprises a series of feeding and recirculation conduits and reservoirs the temperature of which is regulated to perform the polymerization in a controlled manner.

Abstract: This invention relates to a waste treatment furnace and method comprising: Generating a molten metal bed, which moves in a forward direction, such as to define a closed circuit in a cyclical and continuous manner, the surface of said bed comprising at least one essentially-slag-free segment. Loading waste onto the aforementioned essentially-slag-free segment, the waste being dragged by the molten metal bed such that it floats in the mentioned forward direction. Retaining the waste on the surface of the molten metal bed as it moves in the mentioned forward direction. Treating the waste under the effect of the constant and continuous heat exchange generated by the movement of the molten metal bed beneath the waste retained thereon.

Abstract: The invention relates to a process for obtaining ceramic coatings and ceramic coatings obtained. This process allows obtaining coatings of ceramic oxides, such as ZrO2, Al2O3, TiO2, Cr2O3, Y2O3, SiO2, CaO, MgO, CeO2, Sc2O3, MnO, and/or complex mixtures thereof, by means of a high frequency pulse detonation technique in which the relative movement between the combustion stream and the substrate or piece to be coated takes place at a speed that produces an overlap between the successive coating areas exceeding 60% of the surface of a coating area. The allows producing ceramic coatings with a thickness greater than 30 microns in a single pass.

Abstract: The present invention refers to an implantable optical system comprising a central optical part and an annular anchoring part, where said annular part comprises animals cells, including human cells, that encourage the integration of the implant into the ocular tissue of the patient, as well as a system for dosing chemical compounds directed at a particular function, creating a stabilising microenvironment for the presence of the implant in the tissue. A method for obtaining said system by polymerisation and its applications in various types of ocular disorders is also described.

Abstract: The thermal spraying method comprises the following steps: introducing at least one fuel (C) and at least one combustion agent (D) into a combustion chamber (1), generating a combustion process and adding a coating material (F) to the flow of hot gas (E). In addition, a partially ionized gas is generated and said partially ionized gas is introduced into the combustion chamber (1) to provoke the combustion of the fuel and combustive agent. The invention also refers to a thermal spraying device.

Abstract: The present invention develops a manufacture method, via conventional liquid metallurgy, of finished and semi-finished metallic parts as casting, ingot, blooms and slabs in alloys base Fe, base Ni and base Co, microstructurally reinforced with complex molybdenum and titanium carbide particles, by means of their previous elaboration and latter addition to the molten alloy in the melting furnace. Then, when the alloy solidifies, they are inserted and distributed within the grains of the base metallic matrix, enhancing their mechanical properties and behavior at room as well as at high temperatures.

Abstract: The method allows the production of a cermet coating which is composed of chromium carbide particles embedded in a nickel-chromium matrix, produced by thermal spraying on titanium alloys, which avoids the oxidation and the diffusion of oxygen therein at temperatures of up to 700° C. Additionally, a ceramic layer is deposited on the cermet coating which acts as thermal barrier.

Abstract: New melt furnace for casting, of the kind that have a loading nozzle that connects to a liquid metal storage tank and from where an outlet nozzle opens out in the feed runner of the casts, and where, between the liquid metal storage tank and the feed runner of the casts, there is an additional heating chamber by means of a thermal plasma torch and a retaining wall submerged at least partially in the liquid metal between the additional heating chamber and the feed runner of the casts. For application in metallurgic foundry.
