  • Publication number: 20170371224
    Abstract: The invention relates to an electrically controlled interference colour filter comprising at least two transparent electrodes, at least one nematic liquid crystal layer and alignment layers for alignment of the liquid crystals. When an electrical field is applied the liquid crystals can be realigned and thus the transmission wavelength range of the interference colour filter can be shifted.

  • Patent number: 6709757
    Abstract: The invention concerns composites with excellent barrier properties to gases and water vapor. Such composites can be used, e.g., in foodstuff packaging or as technical membranes. The outstanding barrier effect is achieved by arranging on a substrate material, which, for example, may consist of biodegradable polymers, at least two films. At least one of these films consists of an organic-inorganic hybrid polymer (ORMOCER), at least one further film of a further barrier material or of a substrate material.

  • Patent number: RE39790
    Abstract: Reflectors, for example, for lamps used for technical lighting purposes, having a surface which is resistant to mechanical and chemical attack and has high total reflectivity. The body (10) of the reflector, which is, for example, a rolled aluminum product such as a foil, a strip of a sheet, has a surface layer in the form of a layer system containing (a) a pretreatment layer (11), onto which is deposited (b) a functional layer (12) with silanes, having organo-functional groups, of a metal compound, and onto which is deposited (c) a metal-containing reflective layer (13). Layer (a) is deposited on the reflector body and increases the strength of bonding to the above lying layers (a) and (b). Layer (b) effects a flattening and increase in the mechanical strength of the above lying layer (c). The pretreatment layer can be a layer produced by anodic oxidation. The functional layer (b) can be a sol-gel layer.
