Method for Bending and Tempering of Curved Glass Using Flexible Shafts

A method for bending and tempering of curved glass using flexible shafts is provided. During production of curved glass, after discharged from a heating furnace, glass is preformed with the two edge portions of the glass in the transverse direction being kept in the same plane and the middle portion of the glass in the transverse direction gradually sinks along the conveying direction. The glass then enters a forming and tempering section with the two edge portions in the transverse direction being supported and is finally formed and tempered. In this method, when the glass gradually becomes curved and enters the forming and tempering section, the two edge portions of the glass in the transverse direction are always supported by flexible shaft roller beds, thereby preventing the edge portions from being dangled and avoiding the formation of wavy edge portions.

Method of making heat treated coated article using carbon based coating and protective film

A method of making a heat treated (HT) substantially transparent coated article to be used in shower door applications, window applications, tabletop applications, or any other suitable applications. For example, certain embodiments relate to a method of making a coated article including a step of heat treating a glass substrate coated with at least layer of or including carbon (e.g., diamond-like carbon (DLC)) and an overlying protective film thereon. The protective film may be of or include both (a) an oxygen blocking or barrier layer, and (b) a release layer, with the release layer being located between at least the carbon based layer and the oxygen blocking layer. The release layer is of or includes zinc oxynitride (e.g., ZnO.sub.xN.sub.z). Following and/or during heat treatment (e.g., thermal tempering, or the like) the protective film may be entirely or partially removed. Other embodiments of this invention relate to the pre-HT coated article, or the post-HT coated article.

Complex Stress-Engineered Frangible Structures
20170292546 · 2017-10-12 ·

A stress-engineered frangible structure includes multiple discrete glass members interconnected by inter-structure bonds to form a complex structural shape. Each glass member includes strengthened (i.e., by way of stress-engineering) glass material portions that are configured to transmit propagating fracture forces throughout the glass member. Each inter-structure bond includes a bonding member (e.g., glass-frit or adhesive) connected to weaker (e.g., untreated, unstrengthened, etched, or thinner) glass member region(s) disposed on one or both interconnected glass members that function to reliably transfer propagating fracture forces from one glass member to other glass member. An optional trigger mechanism generates an initial fracture force in a first (most-upstream) glass member, and the resulting propagating fracture forces are transferred by way of inter-structure bonds to all downstream glass members. One-way crack propagation is achieved by providing a weaker member region only on the downstream side of each inter-structure bond.
