Abstract: The invention relates to a sandblasting mask (50) as well as its use for the sandblasting of blade tips in a method comprising a step of positioning a plurality of sandblasting masks (50), each blade passing through an opening (58) of a mask and each blade tip extending projecting from the respective mask, the masks being assembled two by two preferably without play; and a step of sandblasting the protruding blade tips of the masks. The masks (50) are preferably produced by plastic additive manufacturing and coated with a polyurea-based coating.

Abstract: The invention concerns a flocculation formulation. The invention also concerns the treatment of mine tailings in the form of aqueous effluents comprising solid particles. With the method of the invention, it is possible to separate all or part of the water from an aqueous effluent comprising solid particles.

Abstract: The present invention concerns an aqueous dispersion comprising particles of water-soluble polymer of average molecular weight higher than or equal to 0.5 million daltons, or of water-swellable polymer, and a mixture of at least one sulfate salt and at least one phosphate salt in weight proportions of between 25:75 and 75:25.

Abstract: The invention relates to methods for improving vehicle steering performance and robustness of that performance through control of non-uniformities in the vehicle's tires, wheels and tire/wheel assemblies as a way to overcome the tendency of many vehicle types to undergo “steering performance loss.” While minimizing lateral force variations (e.g., couple imbalance), a controlled amount of radial and/or tangential force variation is induced in one or more tire/wheel assemblies by means of mass non-uniformity, dimensional non-uniformity, and/or stiffness non-uniformity. For mass non-uniformity, the preferred method includes imparting a controlled amount of excess mass to tires, especially in the tread region, by means, for example, of a heavy splice, an extra fabric piece, or a sector of a tire component having excess mass. The excess mass is meridionally symmetric so as to induce static but not couple imbalance, thereby imparting a “residual static imbalance” (RSI) to the tire.

While minimizing lateral force variations (e.g., couple imbalance), a controlled amount of radial and/or tangential force variation is induced in one or more tire/wheel assemblies by imparting mass non-uniformnity, dimensional non-uniformity, and/or stiffness non-uniformity. The tire non-uniformities are preferably distributed meridionally symmetrically about the equatorial plane of the tire, so as to induce tangential and/or radial force variations but not lateral force variations. Beneficial tangential and/or radial force variations will result from the operation of such a tire, even if the tire/wheel assembly is balanced by weights added to the wheel.
