A building panel, such as a floor panel, having a core comprising at least one or more of a thermoplastic material, a thermoset material, a mineral based material or a combination thereof. The building panel further including a first arrangement, arranged on said core, having a surface layer and a sublayer, where the sublayer is arranged between the core and the surface layer.

It is known that panels moulded for structural use can be subject to undesirable levels of shrinkage and this can complicate their end use or a building made from them. It is an object of the invention to go at least some way to addressing this problem. Accordingly there is provided a method of significantly reducing panel shrinkage in the production of a structural building panel. The method involves spraying polyurethane foam onto a rigid open mould such that the foam substantially embeds mesh, which prevents or significantly reduces shrinkage of the polyurethane foam. A skin of polyurea is then sprayed over the polyurethane to enhance structural strength of the panel.

The current invention concerns coverings such as a floor covering, wall covering or ceiling covering, said covering comprising at least one substrate and at least one surface layer, said surface layer comprising a print pattern and a wear layer, whereby said print pattern is directly applied to said substrate, and further concerns a method to produce such coverings.

Sinusoidal shaped member units and support member units are parts that form pre-stressed assemblies having flexural properties. Sinusoidal shaped members are relaxed material members that have been elastically deformed. Support members maintain the elastically deformed state of the sinusoidal shaped members. The sinusoidal shaped members and support members are organized into pre-stressed curvilinear assemblies containing stored elastic potential energy that is equal to the work done by the forces that deformed their pre-stressed structure. The assemblies' sinusoidal shaped members and support members are adapted to use materials having exceptional mechanical properties and flexural strength. This includes nano-composites. The assemblies' pre-stressed state enhances its mechanical, electrical and structural performance. The size, number, density and possible geometric configurations of the sinusoidal shaped member units and support member units within an assembly/structure is vast. Products of this sinusoidal building system have mechanical and structural applications and can be manufactured using an automated process.

Pipeline apparatus comprising a housing including a riser and a pipeline connector and a device configured to interact with fluid flowing through the pipeline connector, a mounting structure for releasably mounting the device in the riser and seal situated between an inner surface of the riser and an outer surface of the mounting structure, the seal configured to seal against egress of fluid from the apparatus, the mounting structure and the riser each including a part of a locking structure for releasably locking the device in the riser, the device situated in the pipeline connector.

Modular wall panels having a frame of a plurality of frame components and at least one wall sheet affixed to the frame. The frame components may have angled ends, straight ends, or a combination thereof to collectively form a frame which may include corners. Each frame component includes an outer surface with at least one aperture configured to receive and retain an insert therein. The apertures are also configured to permit a cable(s) to pass therethrough for running cables and such through the interior of the wall panel. Connectors and spacers may be inserted into the apertures as inserts and bridge between adjacent panels to selectively connect the panels. Caps may be placed in empty apertures to cover the openings for aesthetic purposes. A wall system includes a plurality of such wall panels connected to one another along the outer surfaces of the frame components of their respective frames.
