  • Patent number: 7147923
    Abstract: A flexible window is formed by a multi-layer sheet having a transparent flexible base layer and one or more transparent flexible protective layers, wherein the protective layers have a greater abrasion resistance than the base layer. The base layer and the protective layers are formed of substantially plasticizer-free polymeric materials.

  • Patent number: 6313335
    Abstract: Coatings are provided with very low surface energies provided by fluorine and/or silicone moieties. Aqueous dispersions of externally chain extended polyurethane compositions terminated by hydrolyzable and/or hydrolyzed silyl groups and containing dispersing or emulsifying groups, particularly carboxyl groups are provided. Also polyurethane dispersions which are substantially organic solvent free which cure to water and solvent resistant, tough, scratch resistant, preferably light stable polyurethane films are provided. Such films are useful as anti-fouling marine coatings. The compound RfR′fCFCOOCH2C(R)(CH2OH)2 is provided.

  • Patent number: 6271309
    Abstract: The present invention provides curable compositions comprising the hydrosilation product of olefin-containing polymers and organosiloxane hydrides. The curable compositions may be cured to form low surface energy cured composition which may be suitable, for example, as antifouling coatings on substrates such as boat or ship hulls.

  • Patent number: 5229453
    Abstract: A hydrophilic polyurethane prepolymer in a compatible, water-miscible solvent or solvent blend having a solids content of greater than about 10 and less than about 50 percent prepolymer in organic solvent that reacts with water at about a 1:1 ratio by volume to produce an excellent gel for use in sealing water containing structures and soil stabilization. In the cure process, the compositions of the present invention expand less than 50%, and preferably less than 30%.

  • Patent number: 5102938
    Abstract: A hydrophilic polyurethane prepolymer in a compatible, water-immiscible solvent or water-immiscible solvent blend having a solids content of greater than about 10 and less than about 50 percent prepolymer in the solvent or solvent blend. This composition reacts with water at about a 1:1 ratio by volume to produce an excellent gel for use in sealing water containing structures and soil stabilization. In the cure process, the compositions of the present invention expand less than 50%, and preferably less than 30%.

  • Patent number: 4508826
    Abstract: Disclosed is the novel bacteriophage TG1, TG1 derivatives, and the corresponding genome or nucleic acid components of such bacteriophages and derivatives of such genome, which are useful as DNA cloning vectors into organisms, such as bacteria, for example, Streptomyces cattleya NRRL 8057; portions of such phage genome are additionally useful as adjuncts in recombinant DNA cloning procedures, for example: (1) to permit the maintenance of cloned DNA in the host, either in an integrated state or as an autonomous element; (2) to serve as promoters for increasing expression of endogenous or foreign genes wherein said promoters are ligated to such genes or otherwise serve as promoters; and (3) to serve as regulatory elements for achieving control over endogenous and foreign gene expression; as cloning vectors, TG1, its deletion mutants, and other derivatives serve for the amplification and transfer of DNA sequences (genes) coding for useful functions, for example, genes necessary for the production of the antibioti

  • Patent number: 4372595
    Abstract: A resiliently mounted automobile bumper which effectively absorbs frontal impact shock by compressive deformation of an energy absorbing material, and tilts or skews during oblique and/or bottoming impact, such as the impact which often results during passage over irregular terrain. The bumper is pivotally mounted at either end by a pair of individually pivoting support arms, and spring loaded against a pair of impact arms. Impact surfaces on the support arms and the impact arms are constructed of an energy absorbing material. Non-frontal impact pivots the bumper assembly away from the impact arms against the loading springs, and a mechanical governor assembly controls the bumper's return to the static position while assuring proper placement of the impact arms.
