Embodiments of the present invention provide reinforcements for inflatable device assemblies. Specific embodiments provide a welded reinforcement for crotch areas of inflatable devices. Particular benefits may be achieved when the areas to be reinforced with the reinforcement system described are non-linear, defining a geometry with at least one curve or angle. Specific aspects of the reinforcement system provide one or more precut gusset elements that are configured to be secured with respect to a crotch area of a base substrate and welded.

The invention relates to a speed reducer (10) with two intermediate transmission lines (16), in particular for a turbine engine, including an input line (12) and an output line (14) driven by the input line via said intermediate lines, said intermediate lines being substantially parallel, characterised in that it includes load-distribution means between said intermediate lines, said load-distribution means comprising ball-and-socket means (30) for rotatably coupling a first end of the input line, first means (34) for damping the radial movements of said end of the input line, and second means (34) for damping the radial movements of a second opposite end of the input line.

A garment for the practice of water sports includes lumens for containing air. The garment is made of two superimposed neoprene sheets forming one or more lumens limited on their periphery by winding or angled welding lines.

A method of bonding materials may comprise defining a bond interface between two materials in a cure zone on a surface of an object, and non-conductively heating the bond interface without directly heating the surface outside of the cure zone. Non-conductively heating the bond interface may involve applying microwave radiation to the bond interface.

A water sport article is provided. The water sport article includes a joint formed between a first panel having a greater thickness than a second panel. The joint includes an overlapping interface between the first and second panels where one or more of adhesive bonding, blind stitching, and taping is used to attach the first and second panels at the overlapping interface.

The presently disclosed subject matter relates to a flotation device suited to teach beginner swimming techniques or provide enjoyment in an aquatic environment while providing flotation to at least a portion of the swimmer's body. The flotation device for aiding a swimmer in a body of water may comprise a body formed from an extruded foam and comprising a top surface, a bottom surface, a first side rail, a second side rail, a leading lateral surface, and a trailing lateral surface, and wherein the extruded foam is a flexible cellular foam. The presently disclosed subject matter also relates to methods of making the flotation device.

The present disclosure is directed towards a hands-free circular flotation device that includes a ring torus shape foam with a cross section of an annulus. Additionally, the ring torus shape foam is configured to fit around a torso of a human body.

The present disclosure relates to a swimming pool and to a method of constructing the swimming pool. The swimming pool includes a basin structure, and a framework affixed externally to the basin structure. The basin structure is made of a bottom surface and a plurality of walls extending upwardly, defining an internal cavity for containing water. The basin structure is formed of a Fiber-Reinforced Polymer (FRP) composite. The framework includes a plurality of support assemblies positioned exterior to the basin structure. The plurality of support assemblies includes stiffened elements provided on one or more edges and corners of the basin structure and extending across a top periphery of the basin structure. The framework including the plurality of support assemblies is further affixed to the basin structure by applying a lamination of the FRP composite and a polymeric material over the basin structure and the framework.
