20110117308 | VACUUM INSULATION BOARD AND METHOD FOR PRODUCING THE SAME - A vacuum insulated panel, comprising a filler and a vacuum-tight high-barrier film envelope, with an air-permeable sheet element serving as a filter material for dust, wherein the sheet element consists of the same material as the sealing layer of the high-barrier film enveloping the vacuum insulated panel and passes through at least two of the sealing seams of the high-barrier film, and to a method for producing such a vacuum insulated panel, wherein the sheet element, in the form of a strip is folded along a central axis, is placed between two sealing films, and is bonded to the inwardly disposed sealing layers of the sealing films such that a joint is formed between the two sealing films, and the two sealing films are sealed together by means of a respective seam on each of the perpendicular sides, the strip-shaped sheet element being co-sealed into these seams. | 05-19-2011 |
20110120620 | Method for the Production of a Vacuum Insulation Element Wrapped in a Film, Filled with Powder - The invention relates to a method for producing an especially panel-shaped vacuum insulation element which is wrapped in a film and is filled with a powder. According to said method, the unmolded, loose powder is filled, particularly poured, into the opening of a bag which is formed from a high-barrier film and is open on one side; a filter material that is permeable to air and impermeable to powder dust is fixed to the internal face of the film bag in the area of the opening of the filled film bag in such a way that the interior of the bag is closed in a dust-tight manner while air can still be discharged; the interior of the dust-tightly closed film bag is then evacuated; and the evacuated film bag is finally air-tightly closed in a vacuum. | 05-26-2011 |

20100047589 | LAMINATES COMPRISING THERMOPLASTIC POLYSILOXANE-UREA COPOLYMERS - Photovoltaic modules are prepared by laminating an active device to a glass cover plate by means of a thermoplastic siloxane copolymer. The siloxane copolymer provides good adhesion, freedom from water absorption, and yet can be reworked either in the field or during recycling of the solar cell components. | 02-25-2010 |
