    摘要: In a method of making a linear composite member, a hollow carrier is provided having a cavity and an inner surface. A curable liquid or gelled resin is applied to the inner surface. A curable foam is introduced into the cavity. The foam contacts the resin when the resin is not more than partially cured, and preferably when the resin has a viscosity not greater than 250,000 centipoise at 25.degree. C. The foam and resin, which are preferably both polyurethanes, are cured together to form a linear composite member having a foam core and a hard resin skin formed integrally. In a preferred embodiment, a reinforcement material, such as a glass fiber web, is embedded in the resin skin.

    摘要: 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.

    摘要: A termite shield according to the present invention provides a physical barrier between a foundation and a wooden building structure, a detection mechanism for detecting termite presence, and a chemical termiticide in the form of a bait block. The termite shield includes a sill plate barrier which is positioned between a masonry foundation and a sill of a wooden structure. An interior bait block holder is removably attached to the sill plate barrier on an interior side of the foundation, and an exterior bait block holder is removably attached to the sill plate barrier at an exterior side of the foundation. The bait block holders may be provided with a block of wood which is inspected periodically to detect the activity of termites. If termites are detected, the block of wood may be replaced with a bait block of cellulosic material containing termiticide. The termite control device addresses the disadvantages of the prior art at least by combining the benefits of a physical termite barrier with the use of chemical termiticides to control termites.
