  • Publication number: 20200254740
    Abstract: The present invention is directed to a fabric composite comprising nylon or polyester fibers having flame-retardant properties without sacrificing many of the desirable properties of the fabric composite. The fabric composite may have external fabric layers (e.g., nylon sheets, etc.) each internally coated with a flame-retardant layer and attached to one another through a thermoplastic polyurethane film. The present invention also provides methods of making such fabric composites.

  • Publication number: 20100151759
    Abstract: The present invention is directed to a fabric composed of nylon or polyester fibers and having both liquid barrier properties and fire retardant properties without sacrificing many of the desirable properties of the fabric. In particular, the present invention helps overcome many of the disadvantages associated with prior art fabrics by providing a fabric having feel and drape of a textile fabric while having good fluid barrier characteristics and fire retardant characteristics. In one embodiment, the invention is also directed to a breathable nylon or polyester fabric having liquid barrier and fire retardant properties. The present invention also provides methods of making such fabrics.

  • Patent number: 7214093
    Abstract: In general, in one aspect, the disclosure describes an apparatus that includes a connector mountable to a circuit board and a bracket attached to the connectors. The connector includes at least one port at least one retractable raised portion formed it at least one side of the connector adjacent to a side having a port opening. The bracket includes a front face for abutting against the side of the connector having the port opening and includes a first opening to provide access to the port. The bracket includes at least one side adjacent the front face that has at least one second opening in alignment with the at least one retractable raised portion so as to enable the retractable raised portion to enter the second opening and secure the bracket to the connector.

  • Publication number: 20060100474
    Abstract: The invention provides new methods for the synthesis of isomeric mixtures of alkenes from ?-olefins or mixtures of internal and terminal alkenes (i.e., predominantly ?-olefins). The invention describes the process for producing an isomeric mixture of at least one internal alkene comprising contacting at least one or a mixture of alkene feedstock with a heterogeneous catalyst comprising a group IV metal oxide at a temperature and pressure conducive to positional isomerization of the double bond. The methods of the invention are particularly suitable for the preparation of isomeric mixtures of olefins suitable for use as additives in the paper making process and particularly as ASA sizing agents.

  • Publication number: 20050161182
    Abstract: The present invention relates to methods for manufacturing paper or paperboard with improved strength and drainage by introduction into the fiber furnish, prior to sheet formation, an aqueous starch dispersion of a gelatinized, self-retaining starch, and an aldehyde generating compound or a glyoxal releasing compound. The present invention further relates to pre-gelatinized starch compositions comprising an aqueous mixture of a pre-gelatinized starch and an aldehyde generating compound or a glyoxal releasing compound.
