Michael F. Lunn 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).

  • Abrasive machining media containing thermoplastic polymer
    Patent number: 8602843
    Abstract: The present invention incorporates at least one thermoplastic or elastomeric polymer in abrasive flow machining media either as the sole or as one of the polymeric constituents. The presence of thermoplastic polymer imparts a greater elastomer characteristic (elasticity, compression resistance, increased relaxation times) as contrasted with traditional media. Enhanced elastomeric characteristics enable more uniform abrasive machining. In a particularly preferred embodiment, silicone- or polyorganosiloxane-based medium contains elastic silicone rubber particles dispersed therethrough to achieve increased relaxation times comparable to those attainable with the inclusion of a thermoplastic polymer.
    Type: Grant
