Publication number: 20060210778Abstract: The invention relates to a method of manufacturing a product which is at least partly transparent and of high optical quality comparable to that of glazing, in which a sheet is placed in at least part of the bottom of a mould, the sheet being of corresponding shape and thermally insulating, then a thermoplastic capable of being fastened to the said sheet in the said product is injected into this mould. The process is distinguished by the fact that the part of the mould whose bottom is provided with the said sheet is kept at a temperature less than that which would be necessary in the absence of the said sheet in order to give the required optical quality. Moreover, the invention relates to the product obtained in this way, to its application as glazing thus obtained for a motor vehicle.Type: ApplicationFiled: May 22, 2006Publication date: September 21, 2006Applicant: SAINT-GOBAIN GLASS FRANCEInventors: Rym Benyahia, Pascal Lefevre

Patent number: 6580917Abstract: A mobile station for the transmission of communication information. The communication information transmitted by the mobile station also includes text information so that it is possible to transmit specific text messages to a base station or to a desired receiver. In order to facilitate the production of the text messages to be transmitted, a number of text messages are predetermined, in which case the predetermined text messages also can be changed, at least partially, and added to. The predetermined text messages are stored in an appropriate memory in the mobile station.Type: GrantFiled: November 29, 1999Date of Patent: June 17, 2003Assignee: Siemens AktiengesellschaftInventors: Pascal Lefévre, Karsten Rudolph

Patent number: 6134851Abstract: The invention relates to an encapsulated window comprising a monolithic or laminated glass and/or plastic substrate (4; 14) provided with a frame (5; 16) made of a plastic material which is overmoulded around the periphery of the substrate. The frame includes, along at least part of its periphery, an essentially U-shaped groove which grips the border (6) of the substrate. The plastic material consists of a thermoplastic polymer or a blend of thermoplastic polymers having a flexural modulus of at least 1200 MPa. The frame grips the edge of the substrate with sufficient rigidity so that the edge of the substrate need not be coated with an adhesive primer.Type: GrantFiled: February 1, 1999Date of Patent: October 24, 2000Assignee: Saint-Gobain VitrageInventors: Jean-Pierre Roze, Pascal Lefevre, Gerard Huchet
