Abstract:
A transparent shock-absorbing laminate to be formed on a glass substrate for a display panel having a fracture strength such that it is fractured by a falling ball impact (drop height: 1.5 m; ball weight: 510 g) corresponding to 79,000 N, the transparent shock-absorbing laminate comprising a shatterproof layer having a shearing modulus of 2null108 Pa or more, at least two fracture-proof layers having a shearing modulus ranging from 1null104 to 2null108 Pa, each having different modulus, and a transparent pressure-sensitive adhesive layer.
Abstract:
The present invention relates to a bulletproof glass window, in particular for use as a lowerable side window of a motor vehicle, with plural glass panes (1, 3, 5) arranged in layers and laminates (2, 4), with at least one laminate being positioned between two adjoining glass panes in each case, in order to join the two glass panes, with a grading or stepped portion that is formed at the edge of the bulletproof glass window and with a projection (8) for lodging the bulletproof glass window in a chassis (14) or door frame, and with a metal armoring which, in the area of the projection (8), at least covers the inner surface of the projection, in the area of the grading or stepped portion a recess (12) being formed on the face, and the metal armoring (6) extending into the recess (12).
Abstract:
A window for an airplane pressurized cockpit having a window opening and a rabbet defining a periphery of the window opening includes first and second sheets of glass, and a separating layer positioned between the first and second sheets of glass and connecting the first and second sheets of glass. The separating layer has a periphery which does not extend substantially beyond peripheries of the first and second sheets of glass. A rigid belt is embedded in the separating layer adjacent the periphery of the separating layer for rigidifying the periphery of said separating layer. The rigid belt ensures that the separating layer is held in place in case of rupture of the glass sheets.
Abstract:
A fireproof transparent pane panel is disclosed which comprises a plastic pane core disposed between panes of inorganic glass. Support elements in the form of plastic threads or strips, arranged unidirectionally or in a lattice, are embedded within the core.
Abstract:
A light diffusing, insulating glass element is disclosed comprising two thin silicate glass panels (1, 2) each about 2 mm thick, and a thick intermediary layer (3) about 15 to 20 mm thick. The intermediary layer (3) is made from a foamed-up acrylate glass having closed bubbles. This layer has a specific weight of approximately 20 to 30 kg/m.sup.3 and a light transmissivity of 60 to 80% for a layer thickness of 20 mm. A shatterproofing splinter-bonding transparent layer (5) is located between one of the glass panels (1, 2) and the intermediate layer (3) and is bonded to them. The other glass panel is bonded to the intermediate layer (3) by means of a thin adhesive coat.The insulating glass element is light and, because of its safety-glass properties, is particularly well suited for ceiling use.
Abstract translation:公开了一种光漫射绝缘玻璃元件,其包括每个约2mm厚的两个薄硅酸盐玻璃面板(1,2)和约15至20mm厚的厚中间层(3)。 中间层(3)由具有闭合气泡的发泡丙烯酸酯玻璃制成。 该层具有约20至30kg / m 3的比重,并且对于层厚度为20mm,透光率为60至80%。 碎玻璃粘结透明层(5)位于玻璃板(1,2)和中间层(3)中的一个之间,并与之粘结。 另一个玻璃面板通过薄的粘合剂涂层结合到中间层(3)。 绝缘玻璃元件很轻,由于其安全玻璃的特性,特别适用于天花板使用。
Abstract:
A laminated article comprising two outer glass layers, a polyvinyl acetal layer disposed therebetween and a fibrous layer encapsulated in said polyvinyl acetal layer; and a process for producing said laminated article comprising(1) maintaining a substantially constant vacuum in a flexible container containing an assembly comprising(a) a first glass layer,(b) a first polyvinyl acetal layer in contact with said first glass layer,(c) a fibrous layer in contact with said first polyvinyl acetal layer,(d) a second polyvinyl acetal layer in contact with said fibrous layer and(e) a second glass layer in contact with said second polyvinyl acetal layer;(2) applying pressure on said container while increasing the same from about ambient pressure to an elevated pressure level and simultaneously increasing the temperature on the contents of said container from about ambient temperature to an elevated temperature level;(3) reducing the temperature on the contents of said container from said elevated temperature level to about ambient temperature; and then(4) reducing the pressure on said container from said elevated pressure level to about ambient pressure.
Abstract:
Laminates of a polyvinyl butyral sheet with a sheet comprising a copolymer of a vinylaromatic monomer with an unsaturated dicarboxylic acid anhydride have high strength and can be made optically clear. The laminates can be in part foamed to provide insulation materials or metalplated to provide tough materials that could be used for example in automotive applications.
