Abstract: The invention is directed to methods involving rewetting of expandable polymers with a wettable liquid to allow for enhanced expansion at or below room temperature without breakage, and in some cases, allows one to achieve a greater expansion ratio than that allowed at elevated temperatures using known methods. The wettable liquid can be formed of a drug and/or an agent, such that the resulting polymer contains and emits the drug upon positioning at a target location of a patient body. The expandable polymer can also have the drug or agent added to its structure at a polymer resin preparation stage, through use of an aqueous solution mixed with one or more fluoropolymers, or in a mixing stage. The present invention also allows one to achieve material with unique properties and handling characteristics. These properties included decreased material thickness, increased density, an altered node/fibril morphology, and a more consistent web in the case of flat material.

Abstract: Method for loading ceramic moulds presenting a die plate having at least one forming cavity in which a die is slidingly received, comprising the following operative steps for each complete loading cycle: preparing a powder layer at least the upper part of which has properties conforming to the required aesthetic characteristics of the exposed face of the tile; transferring said layer to above said at least one forming cavity; depositing into said at least one cavity a powder layer having a thickness greater than that necessary to obtain the desired tile thickness, and before pressing removing, by suction, the surface layer of the powder contained in the mould cavity, without appreciable mixing of the powder present at the interface between the surface layer and the underlying material.

Abstract: The invention relates to molding a right cylindrical body from a settable loose granular composition in a mold cavity, in which a mold cavity (4) is fed with successive charges of the composition in the loose state and each new charge is thrust by means of thrust surfaces (11) into the surface S of the molded composition in order to cause the new charge and the molded composition to interpenetrate in such a manner as to densify the molded composition. The invention is applicable to making a pipe, in particular out of a cement composition.

Abstract: A process for producing patterned elastic sheetings comprises the steps of providing a pair of press rollers having opposite press surfaces respectively formed with at least one protrusion and one indentation, providing a laminate having at least two elastic sheet layers and one interface, placing the laminate between the rollers and causing the protrusion to press the laminate into the indentation so as to deform the laminate until the interface is deformed, cutting the laminate along a cutting plane that passes between the rollers and that passes through the laminate to divide the laminate into two parts, and causing the laminate to exit from the rollers to return the laminate to a non-deformed state. The interface deforms in a direction transverse to the cutting plane, and a pattern is formed in the laminate on two sides of the cutting plane after the laminate exits.

Abstract: From about 50 to about 90% by weight of fibers, in particular wood fibers, and/or pellets made from cellulose or from wood, are mixed with from about 10 to about 50% by weight of a hot-curing resin, each of the percentages by weight being based on the total weight of the mixture. Instead of a single resin it is also possible to use a mixture made from two or more hot-curing resins. The mixture made from fibers and/or pellets and resin is kneaded and homogenized and then passed on to an extruder which has various heating zones in which the mixture is heated. Care has to be taken here that the maximum temperature, arising at the extruder exit, does not exceed about 120° C., since above this temperature the resin(s) begin(s) to cure.
