Various embodiments are directed to an airline carpet kit comprising a plurality of carpet components collectively forming a substantially continuous floor covering, for example, for use within an aircraft interior. Each of the plurality of carpet components comprises a tufted carpet backing having a plurality of carpet tufts extending from a back surface of the carpet backing and above a top surface of the carpet backing; and an edge strip comprising an amorphous plastic material, wherein the edge strip extends around a lateral edge of the carpet backing between a base portion embedded within a back surface of the carpet backing and an edge surface defining a perimeter edge of the carpet component. The edge surface of a first carpet component abuts an edge surface of an adjacent second carpet component to form an at least substantially continuous floor covering for an aircraft interior.

A structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.

A radial bearing having a wear surface with improved wear characteristics comprises a steel support, to which is bonded a metal carbide composite wear surface made by first arranging, within a cavity defined between a steel mold and the steel support, tiles made of microwave sintered, cemented metal carbide, closely packing the voids between the tiles with metal carbide powder, and infiltrating the mold cavity with a metal brazing alloy by subjecting the filled mold to rapid heating. The brazing alloy fills voids between the metal carbide particles, the microwave sintered metal carbide tiles, and the metal support, thereby relatively rapidly consolidating the carbide into a wear layer bonded with the steel support without substantially damaging the properties of the microwave-sintered metal carbide tiles.

At least one layer in a coating located on a surface of a substrate is a domain structure layer constituted of two or more domains different in composition and a thin layer located between the domains and being different in composition from each of the domains. The thin layer is located between any one domain and any another domain and in contact therewith. When the size of each of a plurality of first domains present in the domain structure layer is defined as a diameter of a virtual circumcircle in contact with each first domain, the average value of the size of each first domain is not smaller than 1 nm and not greater than 10 nm and a thickness of the thin layer in a direction of thickness of the domain structure layer is not less than 1 atomic layer and not more than 10 atomic layers.

A mat system is made up of multiple mat modules with interlocking features that allow for separate mat modules to be assembled into different patterns or shapes to cover larger areas as an area mat, define long pathways such as in hallways and customize the shape of the mat may be used to better fit the specific location. The mat modules are secured to each other to provide larger mat systems with a safer and better-looking transition. The mat modules are constructed such that there is a first connecting arrangement and a second connecting arrangement. When the mat modules are assembled, the first connecting arrangement on one mat module will assemble to the second connecting arrangement and an adjacent mat module to provide a secure and seamless connection between the mat modules. These connecting features can be integral to the mat modules or separate pieces.

Disclosed is a tile unit (10) that includes a resin net (20), a plurality of tiles (30) disposed on a front side of the resin net, and a magnet sheet (40) disposed on a back side of the resin net, with the tiles being bonded and fixed to the magnet sheet with the resin net interposed therebetween.
