    Abstract: The invention relates to a method of producing a sound insulation molding with mass (2) and spring (3), wherein both mass (2) and spring (3) are produced on the basis of the same material, in particular polyurethane. For the formation of a mass, reaction substances and fillers are brought into a mold, in particular sprayed in or injected, and brought to reaction. The spraying in or injection is thereby controlled such that the reaction substances and the fillers are supplied in locally different quantity and/or composition into the mold, dependent upon the sound damping to be locally achieved together with the spring, which is then formed on the so-formed mass (2) in the same mold through formation of foam. Through this, with surfaces to be sound insulated which are of the same geometry, three-dimensional moldings (1) of the same geometry can be produced with both different acoustic and also mechanical behavior in predetermined series.

  • Patent number: 7721499
    Abstract: A reverse molded fiberboard panel; a wainscot kit comprising a plurality of differently sized reverse molded panels, and a planar finishing or spacer panel, adapted to completely cover any size wall between a wall base board and a wall chair rail; and a method of reverse molding a loose cellulosic mat, in a single pressing step, to provide one or more relatively high density, raised panels without requiring preliminary pressing, or other pre-shaping step, such as scalping. The reverse-molded panels are molded in a conventional, multi-opening fiberboard press, in a single pressing step process, while achieving excellent transfer of mold detail (embossing fidelity) without visually noticeable fiber fracture.

  • Publication number: 20100027124
    Abstract: An anti-glare film is provided and includes a substrate and an anti-glare layer which is formed on the substrate and contains fine particles. The anti-glare layer has micro concave/convex shapes on the surface. The micro concave/convex shapes of the anti-glare layer are formed by coating the substrate with a coating material containing the fine particles and aggregating the fine particles by a convection of the coating material. A thickness of the anti-glare layer is equal to or larger than a mean diameter of the fine particles and is equal to or less than three times as large as the mean diameter of the fine particles. The fine particles are constructed substantially by fine particles having particle sizes less than twice as large as the thickness of the anti-glare layer.

  • Patent number: 7601416
    Abstract: Flexible composites which are ballistic and stab resistant. The composites are formed from at least one, and preferably a plurality of, fibrous layer comprising a network of high tenacity fibers. A stack of a plurality of fibrous layers is consolidated in a desired pattern over a substantial portion of its surface area which results in areas which are consolidated and areas that are unconsolidated. The unconsolidated areas provide flexibility to the overall composite structure and the structure is resistant to ballistic projectiles and/or sharp objects. Body armor formed from the composites is comfortable to wear and reduces the degree of trauma to the wearer as a result of impact by the ballistic projectile or sharp object.
