Fiber reinforced composite structures having curved stepped surfaces are fabricated by laying up plies of fiber reinforced material over a tool having a stepped tool feature. The plies are rotated about a fixed axis as they are laid up to substantially form a fixed axis rosette pattern. The plies are angularly oriented such that at least certain of the plies have fiber orientations other than 0, +45, −45 and 90 degrees. Potential bridging of the fibers over the stepped tool features is reduced or eliminated by cutting slits in the plies in the area of the stepped features, so that the plies can be fully compacted.

An open-cavity, reduced-pressure treatment device and system for treating a cavity in a patient's body, such as an abdominal cavity, is presented. In one instance, an open-cavity, reduced-pressure treatment device includes a plurality of encapsulated leg members, each having an interior portion with a leg manifold member and formed with fenestrations operable to allow fluid flow into the interior portion, and a central connection member fluidly coupled to the plurality of encapsulated leg members. The central connection member has a connection manifold member. The open-cavity, reduced-pressure treatment devices, systems, and methods allow for, among other things, removal of fluids.

A method of weathering scale and un-scale models comprising creating a custom illustration of a weathering effect such as rust streak, splashed and splattered mud, oil and grease, grime, a crease, a dent, burns and other effects on a background, making an image of the painting and printing the image onto a receptive coating to create a decal, and the decal is applied to the model thereby creating a weathering effect.

The present disclosure provides a support device for conveying at least one solar cell element in a transport direction, wherein the support device comprises a support element configured for supporting the at least one solar cell element and an electric arrangement configured for providing an electrostatic force for holding the at least one solar cell element on the support element.

The present invention provides a mounting mat (30) for mounting a pollution control element (20) or monolith in a pollution control device (10), said mounting mat comprising a layer having a mixture of long and short fibers wherein said short fibers have a length of not more than about 13 mm and wherein said long fibers have a length of at least about 20 mm and wherein the amount of said short fibers is at least about 3% by weight based on the total weight of said mixture of long and short fibers.

The disclosure relates to a tape laying apparatus configured to lay prepreg tape to mould surface. The tape laying apparatus includes a tape supply spool, a compaction head, a cutting tool and at least one travel distance adjustment component. The tape supply spool is configured for the prepreg tape to be wound thereon. The compaction head is configured for delivering the prepreg tape to the mould surface from the tape supply spool. The cutting tool is movable along a cutting path. The cutting tool is configured to cut the prepreg tape passing through the cutting path. The at least one travel distance adjustment component is movably located between the cutting path and the compaction head and configured to push the prepreg tape passing through the cutting path so as to increase or decrease a travel distance of the prepreg tape from the cutting path to the compaction head.

A biocompatible structure includes one or more base structures for regeneration of different tissues. Each base structure includes alternately stacked polymer layers and spacer layers. The polymer layer includes a polymer and tissue forming nanoparticles. The polymer includes polyurethane. The tissue forming nanoparticles includes hydroxypatites (HAP) nanoparticles, polymeric nanoparticles, or nanofibers. The spacer layer includes bone particles, polymeric nanoparticles, or nanofibers. The weight percentage of tissue forming nanoparticles to the polymer in the polymer layer in one base structure is different from that in the other base structures. A method of producing the biocompatible structure includes forming multiple base structures stacked together, coating the stacked multiple base structures, and plasma treating the coated structure.

A method for coating a surface of a supporting element with a layer of ligneous material in order to form a motor vehicle trim element. The method includes the following consecutive steps: precutting the coating layer so as to form at least one precut area in the layer of ligneous material; positioning the layer of ligneous material relative to the supporting element by means of the precut area; and attaching the layer of ligneous material to the surface of the supporting element.

The invention is directed to a mineral wool insulation slab for facade renovations, comprising a rigid insulation slab or lamella having and outer and an inner side, wherein the outer side of the slab comprises an outer layered surface and the innerside of the slab is a mechanically and/or chemically softened layer of the one and same insulation slab. The invention is further directed to a method for manufacturing of such an insulation slab.

A composite protective sheet material for covering a smooth surface of a transparent material, especially but not exclusively for covering the surface of a lens. It comprises a film substrate at least one main surface of which is covered by an adhesive coating. At least a part of the said at least one main surface of the substrate is free or substantially free of adhesive, or has less adhesive applied to it than does the rest of that surface, thereby to provide a finger lift region of the film at an edge of the surface covered thereby.
