Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

An insulated panel assembly having improved insulative R-value. The insulated panel assembly comprises a cover panel, a first insulation layer, and at least one additional insulation layer, wherein the at least one additional insulation layer has a higher R-value than the first insulation layer. The first insulation layer is secured to the cover panel. The first insulation layer further forms at least one recessed portion. The at least one additional insulation layer is positioned in the at least one recessed portion of the first insulation layer. Examples of the at least one additional insulation layer may include vacuum insulated panels and modified atmosphere insulation panels.

A floor panel is of synthetic material and forms a layer-shaped substrate with first and second pairs of opposite edges. The first pair of opposite edges has coupling parts forming a first mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the respective edges, and forms a second mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the panels. The coupling parts on the first pair of opposite edges are realized substantially in the material of the floor panel itself. The floor panel is provided with an edge configuration on the second pair of edges allowing two of such floor panels to be positioned with their respective edge alongside each other and free from mechanical horizontally active locking systems.

An aluminum interconnecting panel support has an insertion end with an inserting member for insertion into another support of a panel assembly. The interconnecting panel support includes a visible portion that is visible to human perception upon interconnecting the support within the panel assembly. The panel support also has a hidden portion that is hidden from perception upon interconnecting the support within the panel assembly. The panel support has a rectilinear body portion connected to the insertion end that spans a length of the support. The panel support has a curved support member that is disposed at a normal to the body portion. The visible portion of the panel support as assembled in the panel assembly includes the body portion. The hidden portion includes the curved support member, fasteners, or both. The curved support member adjoins additional panel members to previously assembled panel members, and it supports the body portion.

A flooring element suitable for connection to other elements in a flooring system. The flooring element comprises a body, a female connector and a retainer. The body defines a connector surface that is horizontal when in use. The female connector comprises a connector recess which is suitable for receiving a male connector and also which defines a connector opening in the connector surface. The retainer is connectable to the body such that, while it is connected to the body, the retainer is movable between and open position and a closed position. When in the closed position, the retainer is arranged to restrict movement of the male connector to guard against the male connector exiting the connector recess through the connector opening. When in the open position, the retainer does not restrict movement of the male connector thereby permitting the male connector to exit the connector recess through the connector opening.

A method for forming a décor on a substrate, including providing a substrate having a surface, forming at least one portion in the surface of the substrate having an extension in a plane situated lower than or above a plane of the surface of the substrate, and digital printing a décor on the surface of the substrate and on said at least one portion by a common print bar, wherein the décor is continuously extending over the surface of the substrate and said at least one portion. Also, a building panel and a set of building panels.

A structure-lining apparatus comprising a plurality of transversely and longitudinally extending panels connectable to a structure and connectable edge-to-edge via complementary connector components on their longitudinally extending edges. Each panel comprises transversely extending edges generally orthogonal to their longitudinally extending edges. Each panel comprises first and second complementary connector components on first and second longitudinally extending edges thereof. The apparatus comprises at least one edge-to-edge connection between a first connector component of a first panel and a second connector component of a second panel wherein a primary male connector component of the second connector component of the second panel is extended into a primary female connector component of the first connector component of the first panel and a secondary male connector component of the first connector component of the first panel is extended into a secondary female connector component of the second connector component of the second panel.

A composition, utility material, and method of making a utility material is disclosed. A composition having an improved setting time may include a plurality of microparticles mixed with a sodium silicate binder and an isocyanate setting agent, where the microparticle composition has a setting time of less than or equal to one hour. A utility material may be a wallboard that includes the composition.

A method and apparatus for minimizing tissue adhesion in a tissue of a subject includes applying light, to the tissue, that reduces at least one adhesion marker in the tissue, the light having wavelengths in at least one of a first wavelength range of 730-770 nm and a second wavelength range of 930-970 nm, wherein the at least one adhesion marker includes at least one of a transforming growth factor beta 1 (TGF-β1), a vascular endothelial growth factor, (VEGF), and a collagen alpha-1(I) chain (COL|α|), and wherein the light is free of wavelengths that increase the at least one adhesion marker.

A panel, including a first edge pair of complementary interlocking retaining profiles on opposing panel edges. One of the retaining profiles has a locking groove having a retaining strip, which protrudes at the free end of the lower groove wall toward the panel surface. The complementary retaining profile has a locking tongue, which, in the joined state, interacts with the retaining surface of the retaining strip, and a play with both vertical and horizontal components so that the retaining profiles are movable perpendicularly to the panel surface and movable perpendicularly to the panel edges and parallel to the panel surface. In a joining step, the bottom side of the locking tongue is laid horizontal onto the retaining strip of the locking groove and then the tongue top side is slid against the inside of the upper groove wall, the tongue top side touching the inside of the upper groove wall in the region of the panel core.
