  • Patent number: 6926939
    Abstract: A self sealing vessel assembly for high pressure microwave assisted chemistry is disclosed. The vessel assembly includes a polymeric cylinder and a circular polymeric cap for the cylinder, the cylinder being closed at one end and open at the other end to receive the cap. The open end of the cylinder has a lip that is beveled inwardly from the open end, and the circular polymeric cap has a beveled lower edge that engages the beveled lip when the cap is place upon the polymericcylinder. For high pressure applications, a choke cylinder depends from the beveled lower edge of the cap, and has an outer diameter substantially the same as the inner diameter of the polymeric cylinder so that the choke provides a self sealing mechanism for the cylinder as pressure from a chemical reaction increases within the cylinder. A composite sleeve surrounds the polymeric cylinder, and includes at least one wound fabric layer in which the winding is selected from the group consisting of filaments and yarns.

  • Patent number: 6846004
    Abstract: A new adhesive coating composition, particularly for use on airbag fabrics, which is composed of a silicone polymer and an appreciable level of a copolymer of ethylene and a polar monomer, is provided. This coating provides excellent adhesive properties to the coated fabric and provides a synergistic effect such that lower gas permeability upon inflation may be obtained with this coating than might be achieved with the silicone polymer alone. Additionally, such a coating allows maximization of the adhesion characteristics on one-piece woven airbag fabric such that blistering upon high-pressure inflation can be reduced, while retaining a high degree of inflation gas retention. Fabric treated with this material in the manner described herein permits reduction in the cost of the coating itself (by reducing the use of expensive silicone polymers). Airbag fabrics and cushions, as well as methods of making and using such a novel airbag coating material are also encompassed within this invention.

  • Patent number: 6734124
    Abstract: Coated inflatable fabrics and more particularly concerns airbag cushions to which very low add-on amounts of silicone-based coating have been applied and which exhibit extremely low air permeability are provided. The inventive inflatable fabrics are primarily for use in automotive restraint cushions that require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones, and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin, substantially uniform silicone coating to provide such necessarily low permeability levels. Thus, the inventive coating comprises at least a single layer comprising a majority of silicone-based material, wherein the total thickness of the single layer is at most about 3.0 ounces per square yard as applied to a target fabric surface.

    Abstract: A heat resistant scattering-preventing composite material is produced by applying, to a substrate, a material comprising a fluorine-containing ethylenic polymer having functional group which is prepared by copolymerizing (a) 0.05 to 30% by mole of at least one of fluorine-containing ethylenic monomers having at least one functional group selected from the group consisting of hydroxyl, carboxyl, a carboxylic salt group, a carboxylic ester group and epoxy, and (b) 70 to 99.95% by mole of at least one of fluorine-containing ethylenic monomers which do not have said functional group. The heat resistant scattering-preventing composite material is produced by applying, to the substrate, the material comprising the fluorine-containing polymer having an excellent adhesive property to the substrate without necessitating complicated steps.

  • Patent number: 6663822
    Abstract: A process for manufacturing an article (10) by forming different portions of the article from different materials including using filler materials that are incorporated into a molten resin prior to forming the article. The selection of the resin and the filler materials impart differing properties to the article in the location where the materials were directed. The filler materials may include ceramic powders, clays, polymeric resins selected for their material properties, recycled materials, whisker materials and the like. The article may be subjected to an adhesion fluid, such as a gas or liquid, after formation in order to adhere all filler particles to the surrounding resin. If the adhesion treatment is acidic in nature, an optional step of neutralizing the article with hydroxides, carbonates or the like may be useful.

  • Patent number: 6660396
    Abstract: A system for permanently associating identifying indicia with a previously manufactured product. Silicone sheet material having imbedded therein a quantity of thermally activatable crosslinking catalyst is secured to the product. An indici-containing element is placed on the silicone sheet material and is then covered by another piece of the same type of silicone sheet material. Heat is then applied to the assembly to cause the pieces of silicone sheet material to crosslink together and encapsulate the indicia-containing element.

  • Patent number: 6630220
    Abstract: A method is disclosed for producing an air-holding vehicle restraint system, wherein a textile fabric is coated on at least one side with a thermoplastic polymeric material and folded along its lengthwise direction to form a closed bottom end and two open upper ends, with the coated side of the fabric facing inwardly. The method also comprises folding a portion of each of the upper open ends of the textile fabric so that they turn outwardly to form a coated platform, and laying a sealing tape upon the coated platform. The sealing tape is then secured to the coated platform and sealed to the coated platform. The method further comprises cutting the coated textile fabric along predetermined side edges to form an air-holding vehicle restraint system of desired shape, and sealing the cut side edges of the coated textile fabric.

  • Patent number: 6610928
    Abstract: A sleeve for providing thermal insulation to elongated substrates is disclosed. The sleeve is formed from a composite sheet having a tough, resilient reinforcing layer to which are attached a metallic reflective layer on one side and a fibrous, non-woven insulative layer on the opposite side. The composite sheet is reverse folded with the reflective layer facing outwardly and the insulative layer facing inwardly. A seam is formed lengthwise along the sleeve in spaced relation to the reverse fold, thereby defining a central space for receiving the elongated substrates. The seam is formed by fusing the inwardly facing insulative layer on each side of the reverse fold together.
