摘要:
A composite structure has a pair of parallel aluminum extrusions bridged by a polymer cap and defining a U-shape hollow. The hollow is filled with an expandable foam that adheres to and mechanically interdigitates with the extrusions, which have channels for receiving insertion legs of the extrusions and have extensions, which the foam encapsulates. End caps may be used to further delimit the hollow. The caps and the foam have a thermal conductivity less than that of the extrusions, providing a thermal break. An upper cap may be used and may incorporate features to compensate for the foam expansion. Excess foam may be trimmed. A forked tool may be used to hold the extrusions during joining.

摘要:
To provide a method for manufacturing a seat pad that can maintain the line speed set in accordance with the speed of foam molding without difficulty. In the state where a molding-surface forming member 30 to be removably mounted on a molding die 20 where a seat pad 3 is foam-molded is removed from the molding die 20, a clipping member 5 (embedded member) is removably secured to the molding-surface forming member 30. Subsequently, the molding-surface forming member 30 to which the clipping member 5 is secured is mounted on the molding die 20. Mounting the molding-surface forming member 30, to which a plurality of the clipping members 5 are secured, on the molding die 20 allows securing the clipping members 5 together to the molding die 20. As a result, it is possible to maintain the line speed set in accordance with the speed of foam molding.

A method for making a phase change device for controlling temperature within a confined environment, comprising providing a phase change material, providing a foam material, absorbing the phase change material into the foam material, and sealing the foam material/phase change material within a protective covering.
摘要:
The object of the present invention is concerned with a stimuli-responsive polymer membrane and method of making the same. The method and making the membrane is a new one The entire body of the responsive membrane is a gel. Gels are used as membranes because they are permeable-swollen network. This disclosure discusses a new combination of cylindrical pores in a swollen network. When the network swells or shrinks the cylindrical pores open or close. Thus, inside the network, one can introduce ligands, function groups which due to specific interaction with some signaling molecules in the surrounding environment can cause swelling or shrinking the membrane and this way they open or close pores. With cylindrical pores in a gel there is the ability to regulate pore size in a broad range and an ability to arrange response by adding some functional groups inside the gel body.

摘要:
A plastic is converted from an initial condition with a higher density into a foamed condition with a lower density using a blowing agent, wherein the plastic is cross-linked prior to foaming by means of a first cross-linking agent and during the foaming by means of at least one second cross-linking agent.

A laminated component, in particular a vehicle body part, includes a substrate and a plastic layer disposed on the substrate. Shrinkage-resistant displacement bodies are embedded in the plastic layer to prevent shrinkage of the plastic layer when it is reacted and cured.
摘要:
A heat insulating paper cup with improved insulation in areas where printed matter exists. The printed matter is applied using a water-based alkyd or epoxy ink. In one embodiment the cup can include a body member having an inside surface and an outside surface, and a bottom panel member having a upper surface and a bottom surface. The body member is coated on its outside surface with a foamed synthetic resin, and on its inside surface with an unfoamed synthetic resin. The bottom panel member is optionally coated on its upper surface with a foamed or an unfoamed synthetic resin. The body member and bottom panel member are oriented and joined to form a seal at an interface between a portion of inside surface of the body member and a portion of the upper surface of the bottom panel member. The printed matter is applied prior to foaming of the synthetic resin on the outer surface of the cup.
