A method of manufacturing a separation membrane structure comprising a step of forming a first to n.sup.th zeolite membranes on a surface of a porous substrate by n repetitions (wherein n is an integer greater than or equal to 2) of formation of a zeolite membrane by a method of hydrothermal synthesis. The following formula (1) is established in relation to the step of forming the first to the n.sup.th zeolite membranes. (Formula 1) N.sub.1/N.sub.0+0.1T.sub.2n/T.sub.12N.sub.1/N.sub.0+2 (Wherein, N.sub.1 denotes a permeation rate of a predetermined gas in the substrate after formation of the first zeolite membrane, N.sub.0 denotes a permeation rate of a predetermined gas in the substrate before formation of the first zeolite membrane, T.sub.1 is a time required for formation of the first zeolite membrane, and T.sub.2n is a total time required for formation of the second to the n.sup.th zeolite membranes.)

A method for recycling concrete mass in a slipform casting process, where the concrete mass is first cast and compacted with a slipform casting machine comprising a restricted cross-section to form a concrete product to be cast and at least one concrete mass tank for feeding concrete mass to the restricted cross-section, and the cast concrete mass is removed from areas of the fresh cast portion of the concrete product, wherein the removed fresh concrete mass is conveyed and dosed back to the at least one concrete mass tank of the slipform casting machine. The invention also relates to a system and a casting machine for implementing the method.

Molding unit for the production of sanitary wares, comprising at least one support frame, at least one first portion and one second portion associated with the frame, bearing respectively at least one first molding component and one second molding component selectively connectable to each other, so as to define at least one molding cavity adapted to receive the casting of at least one pressurized fluid mixture which, once solidified, forms at least one sanitary ware. The first portion and the second portion are connected to the frame in the hanging configuration and are able to be selectively and mutually approachable in a closed configuration, so as to bring into mutual contact the molds to define the molding cavity, and mutually movable away from each other in an open configuration to allow the removal of the sanitary ware once formed. At least the first portion comprises clamping means selectively movable from an inactive position, corresponding to said open configuration, to an operating position, corresponding to said closed configuration, in which they act on at least one abutment zone provided in the second portion.

A method of fabricating a part out of composite material, includes forming a fiber texture from refractory fibers; placing the texture in a mold having an impregnation chamber including in its bottom portion a part made of porous material, the impregnation chamber being closed in its top portion by a deformable impermeable diaphragm separating the impregnation chamber from a compacting chamber; injecting a slip containing a powder of refractory particles into the impregnation chamber; injecting a compression fluid into the compacting chamber, to force the slip to pass through the texture; draining the liquid of the slip via the porous material part, while retaining the powder of refractory particles inside the texture so as to obtain a fiber preform filled with refractory particles; drying the fiber preform; unmolding the preform; and sintering the refractory particles present in the preform in order to form a refractory matrix in the preform.

An absorbent core for an absorbent article is provided an absorbent material, the absorbent core comprising one or more first zones comprising a first amount of absorbent material and one or more second zones comprising a second amount of absorbent material, wherein each second zone is at least partly delimited from the other second zones by the one or more first zones characterized in that the first amount of bulk absorbent material is different than the second amount of absorbent material, each amount of absorbent material being determined as weight per unit area.

Disclosed is a method to form arbitrarily shaped, uniform, lightweight, thermally insulating and acoustically absorptive automotive components with controllable density, thickness, porosity, and surface integrity. The method is based on natural cellulosic fibers such as those found in cardboard and paper and uses a thermoplastic fiber and particle slurry to form fusible components. The method produces components having the benefit of commercially available thermoformed fiber mats or open-cell extruded foam components with excellent acoustical properties, enhanced thermal insulation, and are light weight, which limits engine inefficiency, and the high cost of such products so as to allow large scale implementation.
