  • Device for assembling two elements of materials having different coefficients of thermal expansion
    Patent number: 5439306
    Abstract: Device for assembling two elements made of materials having different coefficients of thermal expansion, which are subject in use to substantial temperature variations, is provided with a combination of a layer of a compressible, heat insulating material, positioned between a support element and an attached element, and an mechanism for maintaining the attached element against the layer, and the layer against the support element. The mechanism is arranged so as to enable relative movement between the two elements in a plane substantially parallel to the plane of the layer. Also, surface portions of the attached element in contact with the mechanism are substantially parallel to the plane of the layer, and a material similar to the material of the layer is positioned between the surface portions and the mechanism. The device is especially applicable to the attachment of insulating elements on a metallic structure.
