The present invention is a polymeric panel system and method for production and use thereof, enabling the rapid construction of a building foundation wall or other structure and in particular a below-grade foundation. The polymeric foundation system includes polymeric wall panels and other components suitable for withstanding lateral and end compression loads. The walls include two parallel faces separated by a series of webs or ribs, where the webs and faces of the wall panels may be formed of a similar polymer material such as polyvinylchloride (PVC). The wall panels and/or other components may be extruded so as to enable the rapid production of sections of wall panels, where the panels may be cut to length and then affixed to adjacent panels to form a foundation wall. The method of affixing adjacent panels may include welding, gluing or other techniques and may be performed on the job site or in a pre-fabrication facility. Furthermore, the wall panels may be co-extruded with an insulating material inserted in the voids between the parallel faces so as to provide improved thermal performance of the foundation as well.

A multiaxis rotational molding apparatus includes a support portion, a molding portion and a control portion. The support portion includes an upstanding arcuate frame section. The molding portion includes an upstanding arcuate mold supporting assembly disposed within and spaced from the arcuate frame section. A mold assembly includes separable mold sections forming a substantially enclosed mold cavity carried within the mold supporting assembly. The control portion includes drive assemblies arranged in a preselected configuration adjacent the arcuate frame section selectively energized in coordination with adjacent drive assemblies for movement of the mold supporting assembly in a selected profile. Programmable memory stores preselected operating parameters. Monitors sense operating information form control components. Circuitry transmits signals from the monitors to a coordinator comparing the operating information with operating parameters stored in the memory to control rotation of the mold supporting assembly in a preselected rotational profile.

A method for producing a foam-containing structure. In a first embodiment, a defoamer is applied to the inner surface of an impermeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer on the inner surface. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core and a solid resin outer layer. In a second embodiment, a permeable carrier is covered with an impermeable release material. A defoamer is applied to the carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier. In a third embodiment, a defoamer and a catalyst are applied to a permeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. At least a portion of the liquid resin layer contacts the catalyst and cures into a solid resin layer. The foamed resin and any uncured portion of the liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier.

Heat blocker system and methods are provided for preventing heat flow into the passenger compartment (118) of a vehicle (10) to reduce a heat buildup therein. A hole (12) may be formed in the door jamb region (16) or other convenient place that is not visible. A tubular insertion member (66) may then be inserted through the hole (12) to an exterior panel cavity (26). Insulation material (68), such as liquid polyurethane resin or other suitable materials, is injected into the panel cavity (26) and allowed to expand and harden. The hole (12) is then anodized or otherwise cleaned. A plug (62 or 64) may be used to cover the hole (12). The type of plug chosen depends on the location of the hole. A heat reflective cover (110) is secured on the exterior surface (112) of the windshield (114) to prevent heat from entering through the windshield (114). The cover (110) has a heat reflective coating (116) such as a metallic silver coating. Cover (110) is secured in place with strips of hook and loop fasteners commercially available under the name of VELCRO.RTM. (120) that can be positioned for each individual vehicle (10). Cover (110) is then locked into position by closing the doors (132 and 134) over the wing flaps (122 and 126). Cover (110) is separated from the windshield (114) to provide a gap (A) between the windshield (114) and the cover (110).

摘要:
In the production of polymeric foam in particular polyurethane foam slabstock, a mixture of foam reactants is allowed to expand in a closed mould while substantially atmospheric pressure is maintained above the upper surface of the foam. After expansion is completed, air is supplied to the foam upper surface and noxious gases in the foam are removed through one or more apertures in the lower region of the mould. Preferably, the air supplied is dry. Removed gases may be collected for re-cycling. Air may be supplied during foam expansion. Various mould aperture arrangements and means for progressively covering the mould are described.
