  • Patent number: 8456280
    Abstract: The invention relates to a product carrier comprising a first packaging unit wherein when opened a first switch of an integrated circuit of the product carrier is opened and at least one second packaging unit wherein when opened a second switch of the integrated circuit is opened. The circuit is configured and/or arranged to cooperate with electronic means so that a value correlating with the degree of filling of the product carrier can be determined on the basis of the number of closed and/or opened switches. Further, an antenna cooperates with the electronic means to transmit said value, the electric power for the electronic means may be introduced without contact, and the first and the second switch are connected in parallel.

  • Patent number: 8163127
    Abstract: A process for manufacturing a packaging material with at least two films (12,16) or foils bonded together via at least one adhesive layer (13) to form a multi-layer laminate (10) is such that at least one adhesive layer is an electron-beam-curable adhesive and the laminate (10) is radiated with electrons in order to cure the adhesive. The laminate is particularly suitable for manufacturing pouch-type forms of packaging, in particular for snack foods. The production of laminate using electron-beam-curable adhesive results in a significant reduction in throughput time and in a reduction of solvent emissions by replacing solvent-based adhesives with electron-beam-curable adhesives.

  • Patent number: 7988805
    Abstract: An unmixed plastic sheet, which is made of a thermoplastic material and which is composed of a number of body segments that are adjacent to one another in a plane, interconnected and made of a closed-cell foam material. The body segments are thermoplastically welded to one another at their abutting lateral faces while forming flat weld seams. The flat weld seams form a plastic intermediate layer, which has few pores, and which is provided in the form of a web structure that, when viewed from above, is reticular and reinforces the plastic sheet. The inventive plastic sheet is preferably used as a core layer in sandwich composites.

  • Patent number: 7182475
    Abstract: A weather and corrosion-resistant reflector with high overall reflection in the visible and infrared wavelength ranges. The reflector contains a reflector body with a reflection surface of an aluminum or aluminum alloy or a reflector body with a reflection coating of an aluminum or aluminum alloy. The reflector also contains an outer, final transparent protective layer of a sol-gel coating which is thicker than 1 ?m. The transparent sol-gel coating is a polymer of cross-linked inorganic siloxanes with alcohol groups that are bonded to the silicon with a carbon bond. The sol-gel coating is produced in a sol-gel process and, after having been applied to the reflector body, is dried and hardened using heat. The protective layer has excellent resistance to weather, corrosion and abrasion.

  • 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.
