摘要： The invention relates to a method and device for orienting magnetisable particles (4) in a kneadable material (3), in particular steel fibres or rings in unhardened concrete by means of an orienting body (1) provided with a non-magnetic wall comprising a front face section (1a) and a rear face section (1b). A kneadable material (33) and the front face section (1a) of the orientation body (1) are first and foremost displaced with respect to each other. The orientation body (1) is also provided with a magnetic unit (2) which is disposed on the internal side of said front face section (1a) and generates a periodically variable magnetic field acting on the kneadable material in order to orient the magnetisable particles (4). Said invention is characterised in that said magnetic field is divided into at least two areas (I II) containing the partial fields exhibiting different forces and/ or different directions of force lines. The partial field of the first area (I) applies long trajectory orientation and attractive forces on the particles, the partial field of the second area (II) releasing orientedly positioned particles.

摘要： The invention relates to a method for production of hollow pre-stressed concrete slabs (1), whereby several strands (2) are tensioned in parallel, either individually or groupwise, between two fixtures arranged separate from each other and are enveloped in concrete in an extrusion process, whereby cavities (3) remain, running between the strands enveloped in concrete and parallel to said strands. According to the invention, conventional hollow pre-stressed concrete slabs and the method for production thereof may be improved such that the economic advantages of using said slabs in construction is improved and the load capacity of said slabs is increased, above all in the transverse direction, making it possible to produce wider slabs, whereby a fibre concrete is used as the concrete material.

摘要： The invention relates to a method and a device for producing fibre cement panels or moulded bodies or such like. The method provided for by the invention comprises the following steps: production of a fibre suspension from a binder which contains cement and in which cellulose fibres or similar fibres are distributed; dilution of the fibre suspension with water to a predefined concentration of solids; transfer of the diluted fibre suspension into at least one perforated cylinder box (6a, 6b), whereby the filling level of said perforated cylinder box (6a, 6b) is adjusted to a set value; application of the diluted fibre suspension onto a perforated cylinder drum (7a, 7b) located in the perforated cylinder box; transfer of the fibre-suspension layer formed on the perforated cylinder drum (7a, 7b) onto a felt strip (8); drying and pressing of the layer positioned on the felt strip (8); removal of the layer from the felt strip (8) for the production of panels or moulded bodies; measurement of the thickness of the layer removed from the felt strip; and adjustment of the bulk density of the suspension supplied to the perforated cylinder box (6a, 6b). Improved control over panel thickness is obtained by modifying the set value of the filling level of at least one perforated cylinder box (6a, 6b) in accordance with the measured thickness of the layer removed from the felt strip (8).

摘要： Method and systems for forming hinged starch-bound matrices. Starch-based compositions are molded between heated molds in order to form a cellular matrix and also to remove water from the starch-based compositions in order to form a binding matrix of solidified starch. The molding apparatus is configured to form one or more creases (230) within the hinge structure (200) in order to define one or more lines upon which the hinge will bend. The molding apparatus is also configured such that the region of the mold corresponding to the inner surface of the hinge area will transfer heat more slowly to the interior skin portion (224) of the inner hinge surface, resulting in reduced thickness of the skin of the inner hinge. This increases the collapsibility, or ability of the inner surface of the hinge to fold or buckle, during the bending action. This in turn reduces the bending radius of the hinge such that the hinging action exerts less strain on the outer surface of the hinge. The inner surface of the hinge may optionally by treated with glycerine or other polyol to soften the inner surface. The exterior skin portion (226) of the hinge may optionally be coated with an elastomeric material, such as polyvinyl alcohol, in order to strengthen the outer surface and reduce its tendency to fracture during the hinging action.
