Abstract:
A support cushion for providing individualized heating and cooling to a user resting on the support cushion is provided. The support cushion includes a body supporting layer and an air distribution layer positioned adjacent to the body supporting layer. The air distribution layer includes a base plate and foam rails positioned at least around a perimeter of the base plate to define a cavity with a support insert positioned within the cavity. A fan is operably connected to the air distribution layer and provides air flow into the cavity of the air distribution layer. Air flow is directed through the support insert and into and through the body supporting layer.
Abstract:
Aqueous polyurethane dispersions and coatings and heat-activatable adhesives made from the dispersions are disclosed. The dispersions include a polyurethane reaction product of a polyester polyol and a polyisocyanate. The polyester polyol comprises recurring units of at least one C2-C6 aliphatic diol, at least one aliphatic or cycloaliphatic C4-C10 dicarboxylic acid, and an aromatic diacid source, which can be recycled PET. The dispersion is formulated using 1 to 3 moles of an acid-functional diol per mole of polyester polyol. Dispersions for the adhesives are produced at NCO/OH molar ratios within the range of 0.90 to 0.98. The adhesives successfully bond a wide range of plastic and metal materials, often demonstrating substrate failure, even with steel. This contrasts with commercial adhesives such as EVA that exhibit only adhesive failure with the same substrates.
Abstract:
A resin sheet includes a porous structure. The porous structure is configured to adjust transmission of a millimeter wave. The porous structure has a relative permittivity varying in stages in a thickness direction of the resin sheet from a plane on which the millimeter wave is incident, the relative permittivity varying such that a difference between average relative permittivities in two adjacent layer portions is a predetermined value or less, the layer portions each having a particular thickness smaller than a wavelength of the millimeter wave. The porous structure has, as pores, only pores each having a pore diameter equal to or less than 10% of the wavelength of the millimeter wave.
Abstract:
The invention describes a device and method for making corrugated products. The device can be used with any substrate and includes, at least, first and second drive rollers for driving a middle substrate and a single wall corrugated product. In other embodiments the invention includes upper drive rollers, lower drive rollers and middle drive rollers for driving an upper substrate, a lower substrate and a middle substrate. The middle substrate is driven between the upper and lower substrates at a higher velocity to form flutes that are anchored between the upper an lower substrates thereby forming a corrugated product. The invention also provides for customized corrugated products having multiple fluted substrates in various desirable arrangements. Examples of such products include mattress, partition panels, other furniture and construction products.

The present invention relates to a composite material comprising nanoporous particles and at least one binder constructed from at least one isocyanate and at least one polymer P selected from the group consisting of polyvinylamine, poly(meth)acrylic acid, poly(meth)acrylic ester, polyvinyl alcohol, polyvinylthiol and mixtures thereof, wherein said at least one binder is used in an amount of 0.1 to 20 wt %, based on the amount of nanoporous particles, a composition for producing a composite material of this type, a process for producing a composite material of this type, shaped articles comprising said composite material and the use of said composite material for thermal and/or acoustical insulation.
Abstract:
A physically crosslinked, closed cell continuous multilayer foam structure comprising at least one polypropylene/polyethylene coextruded foam layer is obtained. The multilayer foam structure is obtained by coextruding a multilayer structure comprising at least one foam composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.
Abstract:
Insulated building products, methods and structure using those products are disclosed. The embodiments described include building materials having a core of encapsulated polystyrene (EPS) which is completely coated with a polymer. The polymer coating provides protection and structural integrity to the foam such that structures made of EPS foam can support multiple human beings without incurring damage. Moreover, additional embodiments are provided in which additional structural integrity is provided by affixing one or more rigid materials to the EPS foam prior to coating. The results, as disclosed, are light-weight, portable building structures that provide protection from the weather and that can be easily heated or cooled.
