  • Patent number: 11518968
    Abstract: A method for expediting the production of aged whiskey. The method uses a system including a tank with a lid containing charred wood slabs and a degasser connected via a conduit to a tube having a vacuum valve, a pressure release valve, and a vacuum gauge. Distillate is delivered to the tank and cyclical steps are applied to age the distillate while regulating the amount of vacuum developed in the tank. The degasser is energized and the vacuum valve is opened, subjecting the distillate to vacuum. The vacuum valve closed and the degasser is de-energized. The pressure in the system is held for approximately one minute. The pressure release valve is slowly opened, allowing the pressure to neutralize to atmospheric pressure. The pressure release valve is closed and the system sits for at least 1.5 hours. Finally, these cyclical steps are repeated for 21 days or more.

  • Publication number: 20140120078
    Abstract: Cross-linked hydrogels comprise a variety of biologic and non-biologic polymers, such as proteins, polysaccharides, and synthetic polymers. Such hydrogels preferably have no free aqueous phase and may be applied to target sites in a patient's body by extruding the hydrogel through an orifice at the target site. Alternatively, the hydrogels may be mechanically disrupted and used in implantable articles, such as breast implants. When used in vivo, the compositions are useful for controlled release drug delivery, for inhibiting post-surgical spinal and other tissue adhesions, for filling tissue divots, tissue tracts, body cavities, surgical defects, and the like.

  • Patent number: 8617584
    Abstract: The present invention relates generally to synthetic polymer compositions that form interpenetrating polymer networks. In a preferred embodiment, the compositions comprise two multifunctionally activated synthetic polymers, along with a tensile strength enhancer. Such compositions form matrices that exhibit superior cohesive strength and in many instances can serve as adequate replacements for surgical means of attaching tissues, such as sutures, sponges and medical staples.

  • Patent number: 7871637
    Abstract: Dry cross-linked gelatin compositions are prepared that rapidly re-hydrate to produce gelatin hydrogels suitable as hemostatic sealants. Gelatin is cross-linked in the presence of certain re-hydration aids, such as polyethylene glycol, polyvinylprovidone, and dextran, in order to produce a dry cross-linked gelatin powder. The use of the re-hydration aids has been found to substantially increase the re-hydration rate in the presence of an aqueous re-hydration medium, typically thrombin-containing saline.

  • Patent number: 6653450
    Abstract: The invention provides recombinant procollagen chains having a natural collagen chain separated from one or two propeptides by one or two non-natural site-specific proteolytic agent (e.g., protease) recognition sites. A wide variety of propeptides and site-specific proteolytic agent recognition sites may be used: the selection of particular site-specific proteolytic agent/recognition site pairs is based on the conformation of the resulting procollagen, the availability of the site-specific proteolytic agent, the compatibility of the proteolysis with production of mature collagen, among other factors. Recombinant collagens chains are produced by contacting the subject recombinant procollagen chains with the appropriate site-specific proteolytic agents. Nucleic acids encoding the subject procollagen chains operably linked to transcription regulatory elements are used in vectors and cells for the production of recombinant collagen.

  • Patent number: 6624245
    Abstract: A method is provided for the rapid formation of a biocompatible gel, and may be carried out in situ, i.e., at a selected site within a patient's body. The method involves admixing a biocompatible crosslinking component A having m sulfhydryl groups wherein m≧2 and a biocompatible crosslinking component B having n sulfhydryl-reactive groups wherein n≧2 and m+n>4, wherein the sulfhydryl-reactive groups are capable of covalent reaction with the sulfhydryl groups upon admixture of the components under effective crosslinking conditions to form a gel in less than one minute. Suitable reaction conditions for carrying out the crosslinking reaction will depend on the particular components and the type of reaction involved; that is, the “effective crosslinking conditions” may involve reaction in bulk or in a solvent, addition of a base, and/or irradiation of the admixture in the presence of a free radical initiator.
