A method of installing a downhole device comprises introducing a downhole device into a wellbore, the downhole device comprising a substrate and a shape memory polymer in a deformed state disposed on the substrate; combining a modified activation material in the form of a powder, a hydrogel, an xerogel, or a combination comprising at least one of the foregoing with a carrier to provide an activation fluid; introducing the activation fluid into the wellbore; releasing an activation agent in a liquid form from the modified activation material; and contacting the shape memory polymer in the deformed state with the released activation agent in an amount effective to deploy the shape memory polymer.

Automotive noise attenuating trim part comprising at least a porous layer whereby the porous layer comprises at least one closed container partly filled with loose particles, whereby the closed container comprises a contact surface formed by a film for contacting a vibrating surface of the vehicle and whereby the surface of the film opposite the contact surface is in contact with at least part of the loose particles, such that the film can transfer vibrational energy from the vibrating surface to the loose particles inside the container.

Multi-layer composite material, production and use thereof A multilayered composite material comprises as components: (A) a sheet material, (B) a material capable of absorbing water or aqueous fluids, (C) at least one bonding layer and (D) a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer,
wherein the polyurethane layer (D) comes into direct contact with sheet material (A) or absorption-capable material (B) in one or more places.

A thermal/acoustic insulation product, such as for an aircraft, comprising a block of flexible, open-celled, cellular foam having a predefined shape and having a thermoformed amorphous film covering that completely envelops the foam block. A process for making the insulation product includes first cutting the block of foam to a predefined shape, such as a shape suitable for placement in an area of an aircraft in need of insulation. Then, a first sheet of film is heated to its melt point and conformed to a first surface area of the block, and a second sheet of film is heated to its melt point and conformed to a second surface area of the block, wherein the first film and the second film are joined to one another at one or more seams. The insulation product may then be installed in an aircraft.

A cleaning device for removing marks from a surface includes a body of melamine foam sponge having a front side and a rear side opposed to the front side, and a holding layer secured to the rear side of the body of melamine foam sponge to prevent relative movement therebetween. The holding layer is preferably a cloth and more preferably natural or synthetic chamois which can be used to wipe and/or buff the surface after rubbing the body of melamine foam sponge on the surface to remove at least one surface mark. The body of melamine foam sponge can be pre-moistened with a liquid such as a disinfecting solution.

A wall structure with a first dampening element (A) includes at least one layer (20,20a-c) configured to form an acoustic inner surface and/or to dampen sound; a first stopping element (B) including at least one layer (30) configured to stop sound; a second dampening element (C) including at least one layer (40,40′,50) configured to form an acoustic inner surface and/or to dampen sound; and a second stopping element (D) comprising at least one layer (60) configured to stop sound; wherein the layers of the first (A) and second (C) dampening element comprise porous and/or open cell material.

An exercise mat comprising: at least one top layer comprising polyurethane, at least one bottom layer, and at least one middle layer disposed between the at least one top layer and the at least one bottom layer.

The waterproof/breathable moisture transfer liner for a running and hiking shoe includes an inner liner selected from technically advanced fabrics which are carefully selected. A series of layers are provided outside the inner liner including foam material layers, breathable membranes, a supportive mesh or a moldable foam, and an outer shell fabric. The applicability of the liner to alpine, snowboard boots, cross country, hiking boots, protective gear and helmets, along with appropriate variations for each application.

A self-inflating stowable bed. The bed includes one or more self-inflating chambers, with each of the self-inflating chambers having one or more polyurethane foam sections therein, with the chamber defined between a first air impervious layer and a second air impervious layer. The self-inflating bed may be evacuated by a household or shop vacuum, and then sealed, rolled or folded, and easily stored or shipped. The polyurethane foam sections may be provided with different members having different indentation force deflection specifications suitable for bed portions and edge of bed portions.

A stretch laminate includes a first layer including an elastomer film, the first layer having a surface, and a second layer including a nonwoven material, the second layer having a surface that is attached to the surface of the first layer. The tensile behavior in the transverse direction of the stretch laminate is within about 2.5 N/cm of the tensile behavior in the transverse direction of the film at an engineering strain of about 1.5, and exists independent of mechanical activation. A method of making the stretch laminate and an absorbent article having at least one region defined by the stretch laminate are also provided.
