Boris G. Varshal has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Biodegradable polymers containing one or more inhibitors and methods for producing same
    Publication number: 20030220436
    Abstract: The present invention relates to biodegradable polymers which can be combined with, impregnated with and/or encapsulate one or more inhibiting formulas. More particularly, in one embodiment the present invention relates to a biodegradable polyester polymer which has been combined with, impregnated with and/or encapsulates one or more inhibiting formulas. This polymer composition can then be further processed into any suitable article. In another embodiment, the present invention relates to a biodegradable polyester polymer which has been combined with, impregnated with and/or encapsulates a desired amount of one or more tarnish and/or corrosion inhibiting formulas. In another embodiment, the one or more tarnish and/or corrosion inhibiting formulas can be dispersed within and through a suitable biodegradable polymer film.

  • Corrosion inhibiting formula and corrosion inhibiting articles using same
    Publication number: 20030213936
    Abstract: The present invention relates to corrosion inhibiting formulas. More particularly, in one embodiment the present invention relates to corrosion inhibiting formulas which comprise a mixture of: (i) at least one volatile corrosion inhibitor (VCI); (ii) at least one antioxidant; (iii) at least one alkali or alkaline-earth metal silicate or oxide; and (iv) fumed silica. In another embodiment, the present invention relates to corrosion inhibiting formulas which comprise a mixture of: (i) at least one volatile corrosion inhibitor (VCI); (ii) at least one antioxidant; (iii) at least one alkali or alkaline-earth metal silicate or oxide; (iv) fumed silica; and (v) at least one chemically active compound. Both of the mixtures described above can further include additional additives. In yet another embodiment, the corrosion inhibiting formulas according to the present invention can be placed in any suitable polymer film and/or polymer article.

  • Tarnish inhibiting formula and tarnish inhibiting articles using same
    Publication number: 20030207974
    Abstract: The present invention relates to tarnish inhibiting formulas. More particularly, in one embodiment the present invention relates to tarnish inhibiting formulas which comprise a mixture of: (i) at least one carrier; (ii) at least one strong alkali compound; and (iii) at least one compound which yields an insoluble compound. These mixtures can further include one or more additional additives such as antioxidants, corrosion inhibitors, etc. In yet another embodiment, the tarnish inhibiting formulas (and in some cases corrosion inhibiting as well) according to the present invention can be placed in a suitable polymer film and/or polymer article.
