Abstract:
Resilient flooring materials made from impregnated papers or foils and core materials are provided. As well, the methods for producing such products are provided. In particular, panels, with a layered structure, created by forming an assembly which consists of laminating a heat-activated resin impregnated decorative layer with printed graphics or a wood veneer decorative layer, a core material made up of one or more heat-activated resin-impregnated papers or other materials including linoleum, natural or synthetic rubber, cork, flexible natural fiber composites or other core materials, and a heat-activated resin impregnated paper backing layer. The heat-activated resin also acts to waterproof each of the layers and abrasion particles may be incorporated to improve wear properties. The panels may also be formed into three-dimensional products.

Abstract:
La présente invention se rapporte à un système de couverture de toiture comprenant : - une membrane d'étanchéité souple (10) posée en bandes jointives à joints plats en lisière et fixées sur un support sous-jacent (2A, 2B, 2C, 1, 4, 5, 6), la membrane détanchéité (10) comportant au moins sur une partie de sa surface extérieure une pluralité de cellules semi-conductrices photovoltaïques se présentant sous forme d'un film mince à monojonction ou hétérojonction; - une pluralité de profilés ou barres (3), dune seule pièce en section transverse, formant une surface continue étanche et dépourvue dorifices sur l'ensemble de leur pourtour longitudinal et fixés à intervalle régulier sur ladite membrane d'étanchéité (10) de manière à former un ensemble rigide.
Abstract:
Fabric laminates having superior resistance to penetration of fragments, such as shrapnel. The fabrics are formed of high-strength fibers consolidated with from about 7% to about 15% by weight of an elastomeric matrix composition, and in combination with protective layers of a polymer film on each surface of the fabric. The fabrics achieve a significant improvement in fragment resistance compared to fabrics of the prior art, while also maintaining excellent ballistic resistant properties.

Abstract:
A composite material formed of reinforcement fibers, acoustical enhancing fibers such as polyethylene terephthalate (PET) fibers or modified polyethylene terephthalate fibers, and one or more organic fibers is provided. The acoustical enhancing fiber may be any fiber that provides increased or enhanced acoustical absorbance, particularly at low frequencies. The composite material may be formed by partially opening wet reinforcing fibers, acoustical enhancing fibers, and organic fibers, mixing the reinforcing, acoustical enhancement, and organic fibers, forming the fibers into a sheet, and bonding the fibers in the sheet. Preferably the reinforcing fibers are wet use chopped strand glass fibers. The composite material may be formed of a single layer of reinforcement, acoustical enhancement fibers, and organic fibers. Alternatively, the composite material may be a multi-layered composite in which the acoustical enhancement fibers are located in an acoustical layer laminated to a thermal layer formed of the organic fibers and reinforcement fibers.
Abstract:
A laminate comprising a layer of elastomeric polyester resin positioned between two nonwoven inorganic sheets, and an electrical device such as a transformer comprising that laminate.
Abstract:
A multi-layered paperboard having a high brightness and exceptional uniformity. The white topped paperboard has a base layer(s) made from wood pulp and a top fibrous layer made of unbleached wood fiber, filler and a binder to create a top fibrous layer of sufficient uniformity at moderate brightness levels. The top fibrous layer optionally contains a coagulant and/or a retention aid. In a preferred embodiment, the top fibrous layer of the multi-layered paperboard product is coated with a coating of additional fillers and binders to produce the desired level of brightness and uniformity. The invention also includes a process for making a multi-layered paperboard.
Abstract:
A cellular foam product is described, wherein the foam includes a polyurethane foam base, having a latex coating on the exterior surface and slightly penetrating the foam interior such that the foam porosity is preferably maintained. The foam has applications in fruit and vegetable sponge drying donuts, the foam allows for uptake of water during fruit drying, while the latex exterior adds to durability. The latex is formulated to include hydrophilic characteristics to aid in water uptake/absorption. Figure 1 is a perspective view of a product made in accordance with one embodiment of the present invention.
