The invention relates to an additive production method involving the production of a layer of geometrically compact particles, having the following steps: a) providing a particle layer depositing arrangement, comprising a first and a second semi-chamber, wherein a partition separates the first semi-chamber from the second semi-chamber, and the partition is permeable for a dispersion medium and impermeable for particles dispersed in the dispersion medium; b) providing a particle dispersion comprising the dispersion medium and particles dispersed therein in the first semi-chamber, the particle dispersion being distributed substantially homogenously in the first semi-chamber; c) generating a pressure gradient between the first and the second semi-chamber such that the pressure gradient in the first semi-chamber causes a particle dispersion flow directed towards the partition; and d) depositing a particle aggregate material comprising geometrically compact particles on the partition by transporting a dispersion agent into the second semi-chamber.

Continuous method including mixing water and cementitous powder to form slurry; mixing the slurry and reinforcement fibers in a single pass horizontal continuous mixer to form fiber-slurry mixture, the mixer including an elongated mixing chamber having a reinforcement fiber inlet port, and upstream of the fiber inlet port is an inlet port to introduce water and cementitous powder together as one stream or at least two inlet ports to introduce water and dry cementitous powder separately as separate streams into the chamber, a rotating horizontal shaft/s within the chamber, part of the chamber for mixing the fibers and slurry and moving the fiber-slurry mixture to a mixture outlet; discharging the fiber-slurry mixture from the mixer outlet; forming and setting the fiber-slurry mixture on a moving surface; cutting the set mixture into fiber reinforced concrete panels and removing the panels from the moving surface.

A method in which a stream of dry cementitious powder passes through a first conduit and aqueous medium stream passes through a second conduit to feed a slurry mixer to make cementitious slurry. The cementitious slurry passes through a third conduit and a reinforcement fiber stream passes through a fourth conduit to feed a fiber-slurry mixer which mixes the slurry and discrete fibers to make a stream of fiber-slurry mixture. An apparatus for performing the method is also disclosed.

A feeding device for a press comprising: a first belt (2), movable in advancement along a conveying direction (X) and passing through a press (11, 12); depositing means (3), predisposed for spreading in a layer an amount (L) of loose material (L) on a movable plane. The device comprises a second belt (4), on which the depositing means (3) operate, located upstream of the first belt (2), which is movable along the conveying direction (X) and is substantially aligned and contiguous to the first belt (2). The first belt (2) and second belt (4) are movable independently of one another.

The present invention relates to a system for the production of thermal insulating, architectural and structural foam materials cast in molded volumes configured for a subsequent milling process, wherein molded foam volumes are cut into dimensional products or product components.

Device for pressing a non-hardened concrete composition into a desired form includes an upper plate with first cavities running through the upper plate, a moulding plate with one or more second cavities whereby the upper plate is located directly above the moulding plate, a bottom plate located under the moulding plate whereby the bottom plate closes the one or more second cavities on the bottom, whereby the upper plate and the moulding plate can move horizontally in relation to each other between a first position in which the one or more first cavities are directly and exactly above the one or more second cavities and a second position in which the one or more first cavities are not above the one or more second cavities, wherein the thickness of the upper plate and not the thickness of the moulding plate is decisive for the thickness of the final article.

A method of producing concrete blocks for creating a surface covering, wherein each concrete block comprises a multiple-layer concrete block body with at least one level concrete block underside and, opposite the at least one level concrete black underside, an essentially flat concrete block upper side, wherein the multi-layer concrete block body comprises a first concrete block layer designed as a facing concrete layer and forming the concrete block upper surface, at least one second concrete block layer designed as a core concrete layer, as well as at least one third concrete block layer forming the concrete block underside. In the method at least one formwork is provided.

A method for infiltrating a porous preform for a gas turbine engine is provided, which comprises providing a chamber for infiltrating a porous preform. The porous preform is positioned within a slurry confinement fixture within the chamber. A vacuum is created in the chamber. A solvent is added to the slurry confinement fixture until a pressure in the chamber is substantially equal to an equilibrium partial pressure of the solvent. A slurry is added to the slurry confinement fixture. The slurry includes the solvent and a particulate. The pressure in the chamber is increased, and the slurry is urged into the porous preform.

The present invention relates to an apparatus and method for three-dimensionally laminating a ceramic denture in a color-and-transmittance variable manner. A base slurry and a light transmissive slurry are mixed at a ratio regulated by a main controller according to a slurry ratio parameter datum, and then a slurry mixture is laid on a substrate by a laying module to form a slurry layer; next, the slurry layer is photocured by a photocuring module according to a laminated graphic under control of the main controller; in such a manner, the slurry layers are laminated and cured one by one so that a denture green body is formed; finally, the denture green body is sintered at a high temperature to form a ceramic denture. The present invention allows each slurry layer to exhibit different color and transmittance, resulting in quite natural gradation of color and gradation of transmittance.
