  • Patent number: 5522216
    Abstract: A refrigerator is provided which combines the benefits of superinsulation materials with thermoelectric devices and phase change materials to provide an environmentally benign system that is energy efficient and can maintain relatively uniform temperatures for extended periods of time with relatively low electrical power requirements. The refrigerator includes a thermoelectric assembly having a thermoelectric device with a hot sink and a cold sink. The superinsulation materials include a plurality of vacuum panels. The refrigerator is formed from an enclosed structure having a door. The vacuum panels may be contained within the walls of the enclosed structure and the door. By mounting the thermoelectric assembly on the door, the manufacturer of the enclosed structure is simplified and the overall R rating of the refrigerator increased. Also an electrical motor and propellers may be mounted on the door to assist in the circulation of air to improve the efficiency of the cold sink and the hot sink.

  • Patent number: 5284700
    Abstract: Mineral fibers, and products (e.g., building insulation products) formed of mineral fibers are treated, and thus rendered fire-resistant, by placing a phosphate-containing compound onto or in close proximity to the mineral fibers. The phosphate-containing compound is at least one which forms a high-temperature protective coating or layer on the surfaces of the mineral fibers. A preferred product of the invention will include two mineral wool layers with a septum carrying the phosphate-containing compound interposed therebetween. Exemplary phosphate-containing compounds include monoammonium phosphate, diammonium phosphate, dicalcium phosphate, monocalcium phosphate, phosphoric acid, aluminum phosphate, tetrasodium pyrophosphate, tetrapotassium pyrophosphate, sodium hexametaphosphate, potassium tripolyphosphate, sodium tripolyphosphate, ammonium polyphosphate, monosodium dihydrogen phosphate, and mixtures thereof.

  • Patent number: 5162401
    Abstract: A sheet molding composition is disclosed which includes a four component resinous system which comprises (a) an unsaturated polyester comprising a polycondensation product of one or more dihydric alcohols and one or more ethylenically unsaturated polycarboxylic acids; (b) one or more low-profile additives which are thermoplastic polymers which cause phase separation and porosity during the curing reaction; (c) one or more olefinically unsaturated monomers which copolymerize with the unsaturated polyester; and, (d) one or more compatible components comprising at least one compound containing one or more polyoxyethane substituents. The compatible component remains compatible when the polyester and monomer cure and imparts improved surface characteristics when added to low-profile resin systems.

  • Patent number: 5145527
    Abstract: Apparatus particularly adapted for applying foamed treating liquor to a flat width of a traveling non-woven textile substrate includes a longitudinal tubular foam distribution nozzle one side of which has a plurality of closely-spaced staggered apertures for engaging and applying pressurized foam widthwise across the substrate and a driven drum opposed to the nozzle engaging widthwise the opposite side of the substrate for imparting traveling movement to the substrate. The drum and nozzle cooperate to compress the substrate therebetween in covering relation over the apertures to prevent lateral escape of the foam therefrom and to confine the emission of foam therethrough, thereby to uniformly control foam application across the substrate width as it travels by the nozzle. Limited contact of the apparatus with the substrate prevents frictional pulling and structural damage thereto. The drum is perforated for escape of the air component of the foam and to enhance foam penetration of the substrate.

  • Patent number: 5143781
    Abstract: We have developed a new pattern for continuous strand fiberglass mat which gives improved torsional rigidity to the molded structure. The pattern is basically an elongated elliptical loop where the strands lay on the conveyor and look like lazy whirl formations or concentric circles with diameters dependent upon properties such as bending rigidity and torsional rigidity. The lay-down pattern looks cycloidal in nature. Elongated elliptical strand loops become further elongated until at some point they also contain "pigtails" or somewhat straight strands with small elliptical loops oriented in the cross-machine direction.

  • Patent number: 5054705
    Abstract: A package winder for a plurality of multiple-filament strands or bundles includes a fixed strand shoe for forming strands, a movable strand shoe for separating the strands into an array of distinctly spaced and oriented bundles and a strand array guide which reciprocates along an axis parallel to the axis of a rotating collet. The guide includes an obliquiely oriented slot which maintains the arrangement of the strands of filaments as they are wound onto the collet. A pair of obliquely oriented parallel guide pins are disposed proximate the transverse limits of the reciprocating guide. The pins engage one or more of the strands, limiting the axial width of the package and greatly improving the edges of the package. The movable strand shoe, strand array guide and pins may be utilized in pairs to produce a pair of packages on a single elongated collet.
