Abstract: A method for breaking down used materials or items, particularly wooden or motor-vehicle items, into reusable components with the use of fractionating tools, with which the accelerated parts of used material interact. The breakdown is effected selectively through impacts, deformation tension, bending stress, friction and/or shearing, with the shape and arrangement of the fractionating tools being set and/or matched to the structure and size of the used feed materials and/or the obtained recycled material.

Abstract: A device and method are provided for pre-disintegrating and cutting fibrous plants to staple length for the separation of fibres and woody parts with the goals to accelerate drying, if applied during harvesting, but mainly to facilitate separation of woody parts before the main fiber recovery machine in order to increase useful performance of same. The device includes a cutting rotor, a supply devoce, cutting blades, and one or more impact or snapping tools. In some fields of application, for example, pulp and paper manufacture or manufacture of insulating material, the degree of pre-disintegration or pre-decortication attained with the device and process, is sufficient so that a further decortication can be dispensed thus improving efficiency.

Abstract: A long fiber-foam composite material, in which the long fibers are bonded to form a loose but dimensionally stable structure with good recovery properties. The long fibers are only partially bonded by foam particles in the shape of nodal points. The unfoamed or unfoamed foam particles are inserted into the structure when the latter is being formed. The unfoamed foam particles inserted into the structure are foamed by reacting or reactivating a foaming agent previously applied to a binding agent to be foamed. The expansion can freely take place without limiting the volume so that a minimal possible thickness can be obtained by complete expansion or in a predetermined volume having a predetermined thickness, for instance, by expansion in a double wall press or a mold.

Abstract: A vehicle body part composed of: an outer skin forming a part of the outer surface of a vehicle; and an inner part disposed between the outer skin and the interior of the vehicle, the inner part performing a thermal insulation function, wherein the outer skin and the inner part enclose an air flow path through the body part adjacent the outer skin.

Abstract: A method of producing a building material uses bast fibers and shives of bast fiber plants as a starting material. The bast fibers and the shives of bast fiber plants are loosened, are metered, and are subsequently fed to an applicator device for liquid additives and/or to a spreading system for solid additives. The bast fibers and the shives of bast fiber plants are subsequently spread in the form of a fleece or a cake.

Abstract: The interior of the passenger compartment of a motor vehicle is provided on its outer limiting surfaces with heat insulating materials, preferably to such an extent that a complete heat insulation is achieved. Such a complete heat insulation makes considerable and weight and energy savings possible when using heating and/or air conditioning systems in vehicles, and a corresponding reduction of pollutant emissions. The ecological effect of this measure is particularly reinforced if renewable raw materials are used as heating insulation materials, either alone or combined with plastics into composite materials in the individual areas of the motor vehicle. By appropriately designing and sizing the heat insulating measures, they can also lead to additional improvements are regards weight, mechanical stability and sound insulation, besides the actual heat insulating effect, substantially improving the usability and ecological compatibility of the motor vehicle.

Abstract: Method for the production of a fiber composite by placing fibers on a support, wherein long fibers are used at least as an essential component for the production of a nonwoven fabric (70). Said fibers are fed to at least one delivery head (A, A1, A2) substantially over the height of a material column and ejected in a sustantially horizontal manner therefrom. A long fiber-air suspension is generated by adding at least one aggregate. The suspension is directly applied on the support, which is especially shaped as a molding strip (14).

Abstract: A device to treat or process and especially to disintegrate materials and compounds characterized by a rotor, to which mentioned materials are fed axially. The rotor centrifugally accelerates the input material to a tool ring rotating around the rotor preferably in opposite direction, in which the tools are arranged radially. The tools of the tool ring intercept the highly accelerated material in flight and induce an extrem shear and bending strain effecting that the material disintegrates at it's natural weak point. The tools are arranged at the circumference at such distances that a laregely open circumference is established. That effects that the disintegrated components of the material can be discharged from the device after the impact without any hindrance even if the material is wet or sticky. The degree of impact of the tools on the material can be adjusted by the regulating parameters.

Abstract: A process for producing a composite structural element, which includes the steps of providing a thin-section wall part, placing the thin-section wall part into a mold, applying reinforcing elements to the thin-section wall part, placing a counter-mold onto the mold for forming a mold cavity, and introducing a binder having a foaming agent into said mold cavity via one of injection cannulas and nozzles, after a set time delay a foaming of the binder occurring for encapsulating the reinforcing elements on all sides.

Abstract: A wall or structural element, preferably for the body or parts of the body of motor vehicles, is formed for dissipating impact forces and introducing them into the load-bearing parts of the body of the motor vehicle. The wall or structural element is a composite element formed of a thin-section wall part and a molding which is bonded to the latter over its full surface area. The molding being composed of reinforcing elements fixed in a foamed binder. The reinforcing elements are derived from renewable raw materials in cut or uncut form, preferably monocotyledons or dicotyledons. Two or more composite elements, in each case having wall parts and moldings, may be bonded to one another to form a joint component, for example a motor vehicle door.

Abstract: A building material includes shives, previously considered to be a waste material. Shives of bast fibers are added to bast fibers and a binder. The shives may contain fibers which are still partially attached to the shives with their natural bond. These partially attached fibers project laterally from the shives in an irregular fashion and are between 2 mm and 100 mm long. The shives and the loose fibers and/or the shives with the partially attached fibers are fed into a coating device for liquid additives and/or into a spreading system for solid additives, and subsequently form a fleece or cake. An air flow may be used for performing a mechanical felting of the fleece. A method and an apparatus for producing the building material are also provided.

Abstract: A method of storing bagasse by piling the bagasse up into a stack on a base structure protected against ground water and having good run-off of surface water. The stack is built up with a substantially horizontal layer structure, wherein each successive layer is piled on only after the preceding layer has completed the phase of most intensive fermentation. The stack is piled up so that it tapers toward the top and forms a ridge, and the top of the stack is covered with a rain-shedding material at the earliest possible time after the top layer has passed its fermentation peak. The rate of fermentation may be controlled by either: (1) de-coring the bagasse before storage; (2) separating the fine material out; (3) slightly pre-drying the bagasse before storage; (4) adding fermentation-controlling or fermentation-inhibiting substances to the bagasse; or (5) providing air ducts in the stack to vent off the moist, damp air.
