Abstract: The invention relates to a method for manufacturing a soluble coffee tablet comprising the following successive steps: a. Taking a quantity of a coffee composition comprising coffee, wherein the coffee consists of soluble coffee particles; b. Compaction of the coffee composition to form a compacted coffee product of three-dimensional form; c. Moistening of said compacted coffee product to moisten the exterior surface of the compacted product; d. Drying of the moistened compacted product to form the soluble coffee tablet. Such a method makes it possible to form a soluble coffee tablet having an internal part and an external part entirely surrounding the internal part, with the external part having a greater density than the density of the internal part. The internal part is a porous core promoting the dissolution of the tablet and the external part forms a thick hardened crust with a density greater than the density of the core, thus increasing the mechanical resistance of the tablet.

Abstract: A method for compacting powdery compositions wherein the composition is compacted down to a reduced volume and the composition is then maintained at constant volume until the solid compact product is obtained.

Abstract: Silicone coating on various soft supports, for instance textiles, made of synthetic polymers (polyamide, polyester) provides an efficient method for producing water impermeable and water permeable coatings, on soft supports, said method enabling to improve permeability to water vapor of the silicones while preserving impermeability to water. The inventive method enabling this consists mainly in: coating one of the surfaces of the support with a film formed by an invert water-in-oil silicone emulsion comprising a continuous oily silicone phase phi s, crosslinkable into elastomer and including a polyorganosiloxane (POS) A crosslinkable by addition polymerization, by cationic process or free-radical process; optionally a crosslinking organosilicon compound B; and optionally at least a catalyst C; an aqueous phase phi a; a stabilizing agent; and in ensuring crosslinking of the silicone phase phi s and elimination of water.
