Jodi Ann Vecchiarelli 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).

  • Impregnation of grinding wheels using supercritical fluids
    Patent number: 7344573
    Abstract: An additive impregnated abrasive article and method for fabricating the same is provided. The method includes providing an abrasive article having a pore structure, dissolving an additive in a supercritical fluid, and exposing the abrasive article to the additive-laden supercritical fluid, so that the fluid disperses through the pore structure. The supercritical fluid is then brought to below its critical point for a period of time sufficient to dissociate the additive from the fluid, so that the additive is deposited within the pore structure of the abrasive article.

  • Supercritical fluid extraction
    Patent number: 6773473
    Abstract: A method is provided for fabricating an abrasive article having porosity. The method includes blending a mixture of abrasive grain, bond material, and pore inducer, in which the pore inducer is soluble in a supercritical fluid, and the abrasive grain and bond material are substantially insoluble in the supercritical fluid. The mixture is pressed into an abrasive laden composite and exposed to the supercritical fluid for a period of time suitable to dissolve at least a portion of the pore inducer. The composite is thermally processed.
