The present invention is directed to a multifunctional waterproof / vapor barrier fabric for use in industrial, medical, outdoor apparel (hunting, fishing, skiing, mountaineering, etc.) and military applications. The invention combines functional elements that are especially suited for the above applications. The fabric comprises a lining with wicking and antimicrobial properties, a vapor barrier film or coating with low Moisture Vapor Transmission Rate (M.V.T.R.), and a woven or knit face fabric enhanced with a hydrophobic face coating. The fabric performs admirably in various uses due in part to the use of hydrophobic adhesive, film and coatings, which renders the fabric subject to negligible moisture gain. The durability and water proof properties of the fabric are enhanced due to the impermeable low M.V.T.R design. The fabric of the present invention incorporates a unique combination of properties that addresses issues commonly associated with vapor barrier fabrics. The invention provides a waterproof / barrier fabric that is desirable to wear in direct contact with the skin to prevent evaporative heat loss in cool or cold conditions. The fabric is also effective when worn over one or more layers of other clothing. The fabric is particularly effective because it is capable of use as a base layer and waterproof shell, which helps to minimize the number of layers of clothing needed in cold weather.

The invention provides for flux-shields wrapped around the flux-sources at the core-end of large power generators. They prevent overheating of all core-end parts under all abnormal conditions of operation. A first flux-shield is an electrically conductive cylindrical shell concentric with rotating end-windings, held outside the retaining ring. The rotating flux source induces eddy currents in the first flux-shield whose flux repels the source flux. Only a small part of the rotating source flux is hence received by all the core-end parts, thereby greatly reducing their temperatures. A second flux-shield comprises an electrically conductive tape wrapped over the ground-insulation of stator bars protruding from the core. Alternating flux generated by the stator bars induces eddy currents in the second flux-shield whose flux repels the source flux. Only a small fraction of the source flux is hence received by all core-end parts, thereby greatly reducing their temperatures. The present invention replaces multiple devices such as step-iron, flux-shields, flux shunts, short-rotors etc, used in the prior-art with only two devices. As a result, the design of the core-end is simplified and the cost of the generator is reduced.
