An industrial fabric such as an endless belt or sleeve for use in the production of nonwovens, and a method of making thereof are disclosed. The fabric includes a plurality of through voids, where each of the voids has a first opening associated with a top surface of the fabric and a first raised edge circumferentially adjacent to the first opening. The voids may each further include a second opening associated with a bottom surface of the fabric and a second raised edge circumferentially adjacent to the second opening, such that the first opening may have a surface area that is larger than or the same as the second opening.

A surround for an electrical box has a sheet of flexible, weatherproof material having a skirt portion, and a flange extending at least outward relative to the skirt portion, the flange defining an opening within the skirt portion sized to provide access to an inner cavity of the electrical box.

A fastening element for attaching to a wall. The fastening element having a contact element having an adhesive surface and a filling opening via which a flowable adhesive agent is capable of being brought between the adhesive surface and the wall. Positioning elements by which the contact element is capable of being positioned at the wall are arranged at the adhesive surface. The positioning element has a width which is variable in dependence on a spacing from the outlet opening. The width reduces at least sectionally as the spacing from the outlet opening increases and is minimal at a maximum spacing from the outlet opening. Accordingly, the adhesive surface is capable of flowing around the positioning element on the introduction between the wall and the adhesive surface.

A hierarchical sandwich core in the form of a honeycomb, i.e. having repetitive and periodic lattice materials. The sandwich core can be made up of a macroscopic honeycomb structure with sandwich cell walls having a mesoscopic cellular core. The longitudinal axis of cells of the mesoscopic honeycomb cell can be perpendicular to the longitudinal axis of the cells of the macroscopic honeycomb structure. Alternatively, if a foam core is used having mesoscopic cells the shape of the mesoscopic cells can be made during the foaming process so that they are elongate in a direction perpendicular to the longitudinal axis of the cells of the macroscopic honeycomb structure.

The present invention relates to a web comprising: discrete extended elements having open proximal ends, open or closed dismal ends and side walls; macro apertures arranged in a staggered pattern; first regions comprising a first top plane; and second regions comprising a second top plane having a length less than or equal to about 0.9 mm, wherein each of the first regions is surrounded by four distinctive second regions, the four distinctive second regions being connected by two adjacent macro apertures in the first direction and another two adjacent macro apertures in the second direction which is orthogonal to the first direction, and wherein each of the second regions is surrounded by two adjacent first regions and two adjacent macro apertures located in a third direction or a fourth direction not parallel either to the first direction or to the second direction.

A plate, a transducer, a method for making a transducer, and a method for operating a transducer are disclosed. An embodiment comprises a plate comprising a first material layer comprising a first stress, a second material layer arranged beneath the first material layer, the second material layer comprising a second stress, an opening arranged in the first material layer and the second material layer, and an extension extending into opening, wherein the extension comprises a portion of the first material layer and a portion of the second material layer, and wherein the extension is curved away from a top surface of the plate based on a difference in the first stress and the second stress.

A method for making an extrusion coated perforated nonwoven web. The method comprises the steps of extruding a molten polyethylene coating onto a nonwoven web, and aperturing the molten polyethylene coating through heat and pneumatic pressure differential to create microperforations therein at a density of between about 35 and about 120 perforations per linear inch. The resulting microperforated nonwoven web is then thermomechanically perforated by feeding it through perforating rolls, at least one of which has raised protuberances to create macroperforations that extend through at least the polyethylene coating. The macroperforations have a density of between about 6 and about 35 perforations per linear inch. The perforated nonwoven web is useful as a topsheet for absorbent articles.

A disposable absorbent having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, is described herein. The topsheet is a two layer composite or laminate web having a first layer and a second layer. The composite or laminate has a first plurality of apertures and a second plurality of apertures, wherein the first plurality of apertures have sidewalls that extend in a first direction, wherein the second plurality of apertures have sidewalls that extend in second direction that is different than the first direction, and wherein the composite or laminate also includes a plurality of embossments which extend in a third direction opposite the first direction.

A composite skin is attached to an underlying structure by fasteners that are countersunk into the structure. The composite skin comprises a thermoplastic material that has been melted and formed into a countersink in the structure using a heated tool.

A flexible padding layer for use during competitive sports is provided. The flexible padding layer is comprised of a plurality of individual padding elements each joined on multiple sides with an adjacent padding element via a thin, connecting section. Each padding element further comprises openings and a three-dimensional surface configuration to allow for consistent mechanical properties throughout the padding layer as a whole.
