  • Patent number: 6395293
    Abstract: The invention is directed to a biodegradable implant precursor having a two-part structure made of an outer sac and a liquid content. The implant precursor is composed of a biodegradable, water-coagulable thermoplastic polymer and a water-miscible organic solvent. When administered to an implant site in an animal, the implant precursor will solidify in situ to a solid, microporous matrix by dissipation of the organic solvent to surrounding tissue fluids and coagulation of the polymer. The invention also includes methods of making the implant precursor, an apparatus for forming the precursor, and a kit containing the apparatus. Also provided are methods of using the implant precursor for treating a tissue defect in an animal, for example, for enhancing cell growth and tissue regeneration, wound and organ repair, nerve regeneration, soft and hard tissue regeneration, and the like, for delivery of biologically-active substances to tissue or organs, and other like therapies.

  • Patent number: 4294586
    Abstract: A gasoline and diesel fuel additive comprising a mixture of alcohol, toluene, and hydrogen peroxide. The preferred ratio is 16/8/1 of these substances. Also for the purpose of quality control when the additive is to be used with diesel fuel, a few drops of diesel fuel and several drops of glycerin are added to the additive mixture to determine if the proper mixture and blending has been achieved. The process of making this additive includes vigorous agitation of the substances as they are blended together in the order of a predetermined amount of toluene being added to a predetermined quantity of alcohol, and then a chosen amount of hydrogen peroxide being added thereafter. Followed by the vigorous blending of these substances, and then immediate putting of the mixture into suitable containers, and tightly sealing the containers to prevent deterioration of the additive mixture.
