    Abstract: An oil reclamation mixture consisting of an activating compound, mechanical coagulant and co-factors. Oil spills and their resultant contamination of life is an ongoing threat that affects the entire bio-ecosystem (marine and terrestrial, alike) and to financial markets. By using a mixture of natural ingredients and chemical principles, the threats to ecosystems are mitigated. Traditionally Oil Dispersants have been used to spread out the contamination, however, in our mixture utilizes non-toxic off the shelf ingredients to provide a product that induces free oil floating on the surface of water to coagulate and form aggregate clumps for easy of skimming off the surface in a clean up operation. Because less toxic materials are used, inhabitants and marine life of the affected area are less impacted financially and physically. The oil can also be reclaimed and recycled out of the recovered materials that are skimmed.

  • Patent number: 8318077
    Abstract: Methods of producing collection tubes are presented. The methods include providing a separator substance that can rapidly polymerize in a short time to a desired hardness and disposing the separator substance within the lumen of the tube. The separator substance is formulated to have a density between an average density of a serum fraction of whole blood and a cell-containing fraction of whole blood, and to be flowable with whole blood. Upon centrifugation of a tube having blood, the separator substance forms a barrier between the whole blood fractions. The barrier rapidly hardens forming a solid barrier when triggered by a suitable energy source.

  • Patent number: 8282540
    Abstract: Methods for using a centrifuge are presented. A vessel containing a sample and a separator substance is placed within a centrifuge. Upon sufficient centrifugation, the sample separates into two or more fractions separated by the separator substance. The centrifuge exposes the separator substance to a sufficient energy to polymerize the separator substance to produce a hardened barrier between the fractions.
