A dam element for the damming of a structure element within a vehicle includes a support element and an expandable element. The support element consists of at least one printed strand of a first material, where the first material is in a solid physical state at least up to a temperature of from 120 C. to 200 C., and the expandable element consists of at least one printed strand of a second material, where the second material is expandable at a temperature between 120 C. and 200 C. The dam element here has, at a point of greatest thickness, measured perpendicularly to a plane of the dam element, at least two, and at most ten, mutually superposed layers.

A method for introducing an active compound into a soft hydrated contact lens comprising the steps of: providing a hypotonic aqueous solution having an osmolarity value less than 150 mOsm and an effective quantity of that active compound, immersing the soft contact lens in the aqueous hypotonic solution, subjecting the contact lens immersed in the aqueous hypotonic solution to mechanical vibrations having a power greater than 100 mW for a predetermined time.

A method of producing a cover for optionally opening or tightly closing an opening in a vehicle roof, the cover having a sheet and a peripheral overmolding. According to the method, a coating is applied in a region which is later visible and which is to be covered, to a portion on the transparent sheet adjacent to the peripheral overmolding to be applied, and the coating is removed once the peripheral overmolding has been applied.

A method of forming a surface covering includes supplying a surface covering raw material. The surface covering raw material includes a substrate and a foamable layer formed on the substrate. A foaming inhibiting composition is applied in a predetermined pattern to the foamable layer formed on the substrate. The foaming inhibiting composition is a non-aqueous composition.

A reinforced composite structure and a method of making a reinforced composite structure are disclosed herein. The structure and methods disclosed herein include a reinforcing flexible material, a barrier layer, and a foam. The barrier layer can be perforated. The foam can pass through the barrier layer to contact and adhere or bond to the reinforcing flexible material. The structure and methods according to the disclosure are useful, for example, in any structural boat component such as stringers, bulkheads, hull and deck stiffeners, beams, fuel tank supports, structural members, long-span stiffeners, corner stiffeners, hull side-to-bottom strengthening, hatch and swim platform reinforcement, insulated compartments, fish boxes, and applications for flat-bed trailers, truck bodies, buses, recreational vehicles, or other types of vehicles, such as aircrafts.

A method for manufacturing a pickleball racket includes the following steps: (a) impregnating a composite material with resin; (b) wrapping a core mold, made of PolyMethylMethAcrylimide (PMI), with at least one location to form an elastic layer; wrapping the composite material around the elastic layer and the core mold to form a composite material layer, to form a semi-finished product; (c) placing the semi-finished product into a mold and heating the mold to a predetermined temperature to form internal pressure within the semi-finished product; (d) stopping heating and cooling the semi-finished product to solidify it; (e) removing a pickleball racket from the mold. The pickleball racket forms an integral structure in the order of a core mold, an elastomer layer, and a composite material layer. The pickleball racket is light in weight and has strength and rigidity. The striking surfaces of the pickle racket has hitting elasticity, and shock absorption.
