摘要： Layered composite materials adapted to be formed into predetermined shaped components disposed for contact with moisture and body fluids having a cover layer for contact with the moisture and body fluids and a foam layer including one or more sorbents in a hydrophilic polyurethane foam matrix, wherein the foam layer is bonded to the cover layer so that moisture and body fluids in contact with the cover layer are transferred through the cover layer to the foam layer. The foam layer is established by combining an aqueous mixture including the sorbent in a predetermined ratio with the hydrophilic polyurethane. The foam layer may include other active ingredients such as odor absorption and bactericidal components, thermal phase change components and finely ground rubber tire materials to vary the characteristics of the composite material. Additionally, citric acid and surfactant compounds may be used to increase the concentration of the sorbent in the aqueous mixture and maintain the pumping fluidity of the aqueous mixture. Methods for making the layered composite materials are also described.

摘要： A process for manufacturing a costume having semi-rigid costume components, and the costume itself. The semi-rigid costume components are capable of being sewn to fabric to form an integrated costume. An embodiment is shown in which the costume includes a semi-rigid muscular torso suitable for a superhero chestpiece. The sewn rigid component is formed from fusing a layer of fabric to a layer of foam and the resulting laminate is vacuum molded into a three-dimensional shape.

摘要： A method of molding, from porous material, a low-density product having an impermeable surface. A mold is provided, which has a cavity, the outline of which defines the outline of the product. The starting material is a flat sheet of plastic foam. The first step of the process, in some cases, is a pre-heating procedure, which softens the material. Then, from this sheet there is stamped a blank having substantially the outline of the desired product, which is then inserted into the mold cavity. The mold is then heated with the blank therein to form the blank permanently into the desired product, after which the mold is quenched in cold water with the product still inside. The product is subsequently removed from the mold and frozen. The result of this molding method is a low-density product having an impermeable surface integral with the foam interior which is suitable for receiving various types of brightly colored finished. It is also contemplated that a non-porous plastic film may be molded in place on the surface of the product.

摘要： Panel construction for forming upholstery panels for use in automotive vehicles and the like, where a plastic substrate which has been formed to a desired configuration, is placed over a grounded metal horn, a layer of adhesive fabric is placed over the substrate, a layer of heat bondable foam is placed over the adhesive fabric, a cover layer is placed over the foam, heat seal punches connected to the positive output of a source of electrical energy are selectively brought in horizontally on all sides of the panel perimeter to successively compress the cover and foam against the sides of the substrate. Electrical energy is applied to the heat seal punches when in selective engaged position to melt the adhesive and the foam, and fasten the cover to the substrate. The punches are withdrawn and the completed panel is removed from the horn.

摘要： An expanded, memory molded, increased density, highly impact-resistant polystyrene construct, and method of making the construct. The construct is formed by molding pre-expanded non-equilibrated polystyrene beads to a first volume, cooling rapidly, and then compression molding to a final, smaller volume. The resultant constructs have increased density, and high impact strength without increase in embrittlement. Also, the construct has "memory" in the sense that it returns substantially to its original shape after impact.

摘要： Method and apparatus for cooling porous materials whereby first gases are passed through a porous material, such as polyurethane foam, in a first zone at a predetermined flow rate to cool the porous material and to remove volatiles therefrom in a first gas mixture which exits the porous material at a predetermined temperature. The first gas mixture is combined with second gases having a temperature which is lower than that of the first gas mixture to form a second gas mixture having a temperature which is sufficiently low to condense or sublime one or more of the volatiles. Thereafter, the second gas mixture is passed through the porous material to filter the condensed or sublimed volatiles thereon and to further cool the porous material. The flow rate of the heated gases is controlled to provide a controlled uniform cooling of the porous material, and additional filters may be utilized to remove particulate matter from either of the heated gases or the cold gases, or both.

摘要： A multi-component sponge has a central or main foam layer of reticulated single cell polyurethane flexible foam and an outer foam layer adhered to each of its two substantially parallel sides so that liquid can flow between the main foam layer and the two outer foam layers. Each of the two outer foam layers is preferably polyurethane flexible foam having a reticulated double cell structure although each could be a reticulated single cell structure having a porosity in the range of 3-110 pores per inch. The main foam layer preferably has a porosity in the range of 3-30 pores per inch. Each of the two outer foam layers is softer than the main foam layer.

摘要： A molded structure 1 produced by extrusion, such as an expanded plastic foam, a sheet, a profile or the like, contains at least 10% by volume of open cells 2, 4 which have a polyhedron-like shape and are adjacent to one another. A higher temperature during the extrusion in comparison with the extrusion of thermoplastic molded structures having a closed-cell structure results in deformation-free opening of the cells. Webs 3 of cell walls 5, 6 remain intact in shape whether they have orifices 7 or no passages, so that the mechanical strength of the cell skeleton or of the space matrix is retained.
