A multilayer structure for transporting or storing gas including, from the inside to the outside, at least one sealing layer and at least one composite reinforcing layer, the innermost composite reinforcing layer being welded to the outermost adjacent sealing layer, the sealing layers being a composition predominantly including at least one semi-crystalline thermoplastic polymer P1i (i=1 to n, n being the number of sealing layers), the Tm of which is less than 280 C., and at least one of said composite reinforcing layers being a fibrous material in the form of continuous fibers impregnated with a composition predominantly including at least one thermoplastic polymer P2j, (j=1 to m, m being the number of reinforcing layers), the thermoplastic polymer P2j having a Tg greater than the maximum temperature of use of the structure (Tu), with TgTu +20 C., Tu being greater than 50 C.

A coating free, finished golf ball and a method of forming a coating free, finished golf ball are disclosed herein. The golf ball has an outermost surface defined exclusively via the cover. The cover disclosed herein can be formed from a polyurethane, polyurea, or hybrid of polyurethane-polyurea, in some examples.

A method of forming a decorative panel includes pressing a decorative layer in relation to a substrate. The decorative layer includes one or more decorative elements, such as one or more of coloration, text, graphics, or the like.

A method of forming a composite panel includes providing an initial composite material, heating the initial composite material, molding the initial composite material to form a preliminary composite panel having a main body connected to an outer edge and a laminate layer secured to the outer edge, and folding an exterior edge portion of the outer edge over an interior edge portion to provide an external folded edge having the laminate layer on at least a portion of an outer surface.

The present disclosure provides a method of applying a protective film on at least one portion of a wind turbine blade, a wind turbine blade, and an apparatus for forming a groove on a surface of at least one portion of a wind turbine blade. The method of applying a protective film on at least one portion of a wind turbine blade comprises providing the at least one portion of the wind turbine blade; forming a groove on a surface of the at least one portion of the wind turbine blade, thereby delimiting a first region of the surface of the at least one portion of the wind turbine blade from a second region of the surface of the at least one portion of the wind turbine blade, wherein the first region of the surface of the at least one portion of the wind turbine blade includes the groove; covering the first region of the surface of the at least one portion of the wind turbine blade with a protective film; and pressing an edge region of the protective film in the groove, thereby inserting the edge region of the protective film in the groove.

An anti-ligature door handle is disclosed. The door handle assembly includes a handle, an escutcheon, and a PTFE coating. The door handle assembly is constructed in a manner where a cord or rope cannot readily be anchored to any surface. This is due to the sloping geometry of the door handle assembly along with the low friction coating. The low friction coating may be a sintered and skived sheet of PTFE or a sprayed layer of PTFE that ensures sufficient strength, resilience, and friction properties when applied.

A method for relining a pipeline includes providing and using a composition that includes (a) a resin crosslinkable by action of a photoinitiator that is activated with actinic light, (b) a resin crosslinkable by action of a co-hardening compound; (c) a photo-initiator compound that can be photoactivated by irradiation with actinic light; and (d) a co-hardener compound added before use that is a semilatent co-hardener or a co-hardener at room temperature. A kit for relining a pipeline according to this method includes (1) a container containing (a), (b) and (c); (2) a container containing (d); (3) a substrate for impregnation with the composition resulting from mixing the contents of container (1) and container (2); and, optionally, (4) a source of actinic light and a generator of a flow of gas or liquid at adjustable pressure.

Process for coating a preformed substrate (1), comprising providing a semi-finished product (2) comprising the preformed substrate (1) and a coating layer (3), providing a mould (4) comprising a first (5) and a second half-mould (6), the first half-mould (5) comprising an elastically deformable membrane (8) which at least partially forms a respective conformation surface (7), arranging the semi-finished product (2) on the second half-mould (6), putting under depression a fluid (11) acting on the membrane (8) to maintain the membrane (8) adherent to a main body (50) of the first half-mould, closing the mould (4) maintaining a free distance between the conformation surface (7) of the first half-mould (5) and the semi-finished product (2), pressurizing the fluid (11) to expand the membrane (8) towards the second half-mould (6) for compressing the semi-finished product, maintaining the membrane (8) in the second configuration, heating the semifinished product (2) for firmly fixing the preformed substrate (1) and the coating layer (3) to each other.
