  • Electrophoresis gels and cross-linking agents for their preparation
    Patent number: 6197906
    Abstract: This invention relates to the separation of molecules on polymer gels, in particular to novel cross-linked polymer gels comprising the cross-linking moiety of for formula (1) and their preparation, the separation of molecules by techniques such as electrophoresis using these gels, novel cross-linking agents useful in the preparation of the gels, and novel intermediates useful in the synthesis of the cross-linking agents. The invention is especially suitable for electrophoretic applications.

  • Durable motor insulation
    Patent number: 5821284
    Abstract: Provided is an insulation for rocket motors that uses two ingredients not previously combined in such insulation before. These ingredients are ammonium sulfate and antimony oxide, which when combined, have a synergistic effect that reduces the ablation rate significantly. Such insulation also includes EPDM rubber and aramid fibers. The inventive insulation also exhibits better tear resistance and propellant-to-insulation bond peel strength, compared with prior art rocket motor insulation.
