  • Patent number: 7279437
    Abstract: The present invention teaches that a tightly woven, and strong panel of fiberglass may be impregnated with sodium silicate in order to produce a strong and fire resistant panel. The impregnation may occur by spraying, by rolling or by other means, and the drying process of the sodium silicate occurs after it has been impregnated into the fiberglass panel. The present invention further teaches that a fire door core may be mass produced from fire resistant panels and the core rated for fire safety by a rating agency, thus allowing door manufacturers to produce doors using that core without individually certifying each model of door. The present invention further teaches a method of manufacture of the a sodium silicate building panel, comprising the steps of producing a tightly woven fiberglass panel, impregnating it with sodium silicate, and allowing it to dry.

Compression zones of increased density form between the indentations and a first face of the mat. By spacing the forms appropriately, the compression zones overlap, and the first face of the resulting consolidated board is provided with substantially uniform density. Since the entire board is not compressed to the same degree, its overall thickness is enhanced while the density of the first face of the mat is increased, and relatively little material is used.

  • Patent number: 6890621
    Abstract: Improve the strength of the stretch blow receptacle and make the heat resistant treatment easier, by making the receptacle wall cross-section multi-layered in view of crystalline density, and the crystalline density of the surface layer high density. The inventions concerns a thin plastic receptacle 2 molded by stretch blowing of a bottomed preform 1 in the longitudinal and transversal directions. The wall cross-section is composed of inside and outside surface layers 2a whose crystalline density is high by stretching, a core layer 2b presenting a lower density than the surface layers 2a, and an intermediate layer 2c presenting a graduated density between both layers 2a, 2b.

  • Patent number: 6890633
    Abstract: From about 50 to about 90% by weight of fibers, in particular wood fibers, and/or pellets made from cellulose or from wood, are mixed with from about 10 to about 50% by weight of a hot-curing resin, each of the percentages by weight being based on the total weight of the mixture. Instead of a single resin it is also possible to use a mixture made from two or more hot-curing resins. The mixture made from fibers and/or pellets and resin is kneaded and homogenized and then passed on to an extruder which has various heating zones in which the mixture is heated. Care has to be taken here that the maximum temperature, arising at the extruder exit, does not exceed about 120° C., since above this temperature the resin(s) begin(s) to cure.

  • Patent number: 6890622
    Abstract: An in-line formed, non-laminated web is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web can be formed by selective deposition of airlaid materials including absorbents, such as pulp and superabsorbents, together with binder fibers. The web so constructed will have a plurality of intermingled lower basis weight areas and higher basis weight areas coexisting and distributed in at least a central region of the web, the alternations crossing the X axis or Y axis, or both, of the web, with the higher basis weight areas being a greater thickness in the Z-direction than the lower basis weight areas. The web so constructed will further have no discrete material boundaries between the lower basis weight stripes and the higher basis weight stripes. Further the necessity of later processing on the web to achieve a ridged structure is removed and the fibers will remain whole and undisturbed.

  • Patent number: 6878466
    Abstract: Reliable, flaw-tolerant brittle materials are produced by incorporating layers under residual compression on the surface and throughout the bulk of the material that act to trap and contain the propagation of otherwise catastrophic cracking. The residual compression within these layers acts to reduce the stress intensity of the cracks, thereby causing them to arrest until further loading is provided. This highly desirable stable, subcritical crack growth mode persists with increased loading until the applied stress is large enough to drive the crack completely through compressive region, after which failure occurs. The exact level of stress needed to accomplish this is dictated by the architectural design of the compressive layers such that the material can be designed to have any minimum strength desired, within the limits of the materials system used. This results in a truncation of the strength distribution, such that there is virtually zero probability of failure below this minimum value, i.e.

  • Patent number: 6852654
    Abstract: The invention is directed to a hydroentangled nonwoven fabric, the outer surface of which exhibits highly entangled fibers whereas the inner layer exhibits lightly entangled fibers. In particular, the present invention contemplates that a fabric is formed from a fibrous batt that is subjected to fluidic energy, preferably hydraulic energy, applied to one or both faces of a fibrous batt. The hydraulic energy is moderated against the basis weight of the fibrous batt to achieve the degree of surface entanglement desired. Fabrics formed in accordance with the present invention exhibit a sufficient degree of softness and non-linting performance, while providing the necessary resistance to tearing and abrasion, to facilitate use in a wide variety of applications such as cast padding or orthopedic wraps.
