Title: Conductive fabric seal

Abstract

Disclosed are several examples of a system and method for detecting if an article is being tampered with. Included is a covering made of a substrate that is coated with a layer of an electrically conductive material that forms an electrically conductive surface having an electrical resistance. The covering is configured to at least partially encapsulate the article such that the article cannot be tampered with, without modifying the electrical resistance of the electrically conductive surface of the covering. A sensing device is affixed to the electrically conductive surface of the covering and the sensing device monitors the condition of the covering by producing a signal that is indicative of the electrical resistance of the electrically conductive surface of the covering. A measured electrical resistance that differs from a nominal electrical resistance is indicative of a covering that is being tampered with and an alert is communicated to an observer.

  • Electrophoretically active sol-gel processes to fill, seal, and/or density porous, flawed, and/or cracked coatings on electrically conductive substrates. Such coatings may be dielectrics, ceramics, or semiconductors and, by the present invention, may have deposited onto and into them sol-gel ceramic precursor compounds which are subsequently converted to sol-gel ceramics to yield composite materials with various tailored properties.

  • A seal ring assembly for use in an end face mechanical shaft seal is described comprising: an annular ring casing having a substantially annular end face formed therein with a substantially annular groove; and a seal ring partly received in the groove and secured to the ring casing by an adhesive. The seal ring being formed by segments each having a substantially accurate cross-section, substantially cylindrical radially inner and outer surfaces, axial end faces and side faces. The segments being disposed in the annular groove with one of the end faces of each segment received in the groove and themore » other end face being offset from the end face of the ring casing axially outwardly thereof. The segments being arranged in circumferentially side-by-side abutting relationship with each other to form the seal ring. The other end faces of respective segments being included in substantially the same plane to provide a substantially smooth and circumferentially substantially continuous sealing surface.« less
