  • FIBER FORMATION BY ELECTRICAL-MECHANICAL SPINNING
    Publication number: 20090102100
    Abstract: A method of fiber formation by electrical-mechanical spinning is disclosed. A liquid starting material is fed to a rotating annular member such as a spinning cup. The liquid material is directed by centrifugal force to the periphery of the annular member where it is expelled in fibrous form. An electric charge is imposed on the liquid while on the annular member or while immediately being expelled from the annular member.

  • Method and apparatus for mixing and applying a multi-component coating composition
    Patent number: 7217442
    Abstract: A method of applying a multi-component coating of a desired composition over a substrate includes providing a coating device in flow communication with a first coating component having a first rheological profile and at least one second coating component having a second rheological profile. The method further includes defining a desired ratio of the first and at least one second coating components to provide a coating of a desired composition, and selecting the rheological profiles of the first and at least one second coating components such that the coating components are supplied at a desired ratio.
