Abstract: For heterogeneous materials such as refractories and carbon electrodes, the measurement the elastic properties of the material is difficult to achieve with high level of repeatability. The present invention is directed to a method and system for the elastic properties measurement of a material including the Elastic and Shear Modulus, as well as the Poisson's ratio of heterogeneous materials, at room and high temperature, according to a non destructive acoustic technique.

Abstract: An apparatus to prevent strip material from falling off the edges of a strip material package when unwinding. The package comprises a generally cylindrical and flangeless core around which the strip material is wound transversely in a plurality of overlapping layers. The apparatus also includes an idler roller. When unwinding, the strip material goes around the idler roller, then around the package, generally in its central portion and then again around the idler roller before being fed to a laminating machine. A method to use the apparatus is also provided.
