  • Patent number: 7527868
    Abstract: A transparent glass substrate (1, 1?, 1?) coated with one or more thin layers (6, 16, 28) is disclosed, wherein the thin layer most distant from the glass substrate is a composition comprising silicon nitride, carbonitride, oxynitride or oxycarbonitride, said thin layer most distant from the glass substrate being covered by a second layer (7, 17) which protects against high-temperature corrosion.
    Type: Grant

  • Publication number: 20070041067
    Abstract: The present invention concerns a strip for safeguarding a document, comprising a support on which there is formed in the longitudinal direction of the strip an alternation of generally metallised regions and generally transparent regions, said alternation being capable of establishing a contrast on a scale identified as global at the level of the document to be safeguarded in such a way as to constitute protection against reproduction of the documents with which the strip will be associated, characterised in that the strip also comprises optically active elements in association with the generally metallised regions and/or the generally transparent regions of the strip to produce an optical effect on a scale identified as detail at the level of the document to be safeguarded, said optical effect making it possible to constitute a recognisable sign for identifying said document. The present invention finally concerns a security document incorporating a strip as set forth hereinbefore.

  • Patent number: 6582809
    Abstract: A glazing assembly is provided made of at least one transparent substrate having a stack thereon that includes an alternation of n functional layers and n−1 coatings, wherein the functional layers have reflection properties in the infrared and/or solar radiation and where n≧1 and where, in order to maintain the quality of the stack when the substrate is subjected to a heat treatment step, at least one of the following must be satisfied: the coating placed on top of at least one of the functional layers includes at least one barrier layer providing a barrier to at least oxygen and water; and at least one absorbent or stabilizing layer made of a material capable of absorbing or stabilizing the consituent material of the functional layer forms a part of either the coating placed on top of the functional layer and under the barrier layer or the coating placed beneath the functional layer; and a method for production of the glazing assembly.
