    摘要: The present invention relates to an equipment for measuring the rheological properties in fluids, which enables capillary flow to be studied and the rheological properties of all types of fluids such as dispersions, organic and inorganic fluids to be determined, in a pressure range comprised between 0-4000 bar and a temperature range from -180 °C to 800 °C; wherein the fluid to be analysed is passed through a capillary with a circular cross section; which has the particular feature of having an independent circuit for loading the fluid to be analysed in the capillary that is thermally protected by means of a thermostatic chamber, and an independent circuit of pressurisation fluid, all this being automatically controlled by means of a computer that manages all the regulation actions and receives the data of the pressure variations of the fluid as it passes through the capillary with which it calculates the rheological values of the fluid.

    摘要: The invention relates to a novel method for producing magnets (especially applicable to the production of magnets containing rare earths). The novelty of the method lies in its use of a type of electrical consolidation (such as so-called electrical resistance sintering, ERS, or so-called electrical discharge consolidation, EDC, but not necessarily one of the these) as a substitute for the conventional cold pressing and sintering method which is usually used. The method according to the invention achieves: (1) combining the compacting/sintering steps, significantly cutting the duration thereof and reducing the magnitude of the working pressures; (2) implementing the steps of magnetic aligning, pressing/sintering, heat treatment and magnetising in the same matrix; and (3) rendering superfluous the use of protective atmospheres during the sintering process.

    摘要: The invention relates to a method for the catalytic oxidation of benzene to phenol, where the oxidant is hydrogen peroxide and the reaction medium is a mixture of acetonitrile and water, the catalytic oxidation of the benzene being generated by a catalytic system based on copper compounds of formula Tp x Cu(NCCH 3 ). Said method enables approximately 39% conversions of the starting hydrocarbons with phenol selectivities higher than 92% in processes taking place at 60°C with reaction times of between 2 and 4 hours.
