Abstract:
A two-piece article for enclosing an electronic device or for storing food and methods of making the same. The two-piece enclosure includes a light absorbing film at the interface between two segments. The two segments are joined together by a bond. The resultant enclosure includes high tensile strength glass part.
Abstract:
Unión mecánica hermética entre vidrio y metal para tubos receptores usados en las plantas solares, de las que utilizan un fluido portador del calor, que emplea una fuerza mecánica para realizar el sellado entre los tubos interiores metálicos y los tubos exteriores de vidrio, entre los que se establece un elevado vacío para evitar pérdidas térmicas, utilizando para tal sellado una junta metálica flexible y deformable, la cual, debidamente comprimida, se adapta a las superficies correspondiente de los tubos a sellar, y ello para conseguir de este modo la debida estanqueidad entre los respectivos tubos, previéndose además un eventual sistema continuo para mantener el necesario vacío entre ambos tipos de tubos.
Abstract:
The invention relates in a first aspect to a process for bonding by molecular adhesion of two substrates to one another during which the surfaces of said substrates are placed in close contact and bonding occurs by propagation of a bonding front between said substrates, characterised in that it comprises prior to bonding a step consisting of modifying the surface state of one and/or the other of said substrates so as to regulate the propagation speed of the bonding front. The surface state is modified by locally or uniformly heating the surface of one and/or the other of the substrates to be bonded, or again by roughing the surface of one and/or the other of the substrates.
Abstract:
The invention relates to using the heat generated during thermal treatment of one or more glass sheets to melt solder. In one nonlimiting embodiment, a lead providing external access to an electrical conductive arrangement, e.g. a conductive member between and connected to spaced bus bars between laminated sheets has an end portion of a connector, e.g. a lead soldered to each of the bus bars during thermal processing of the sheets, e.g. during the lamination of the sheets during a windshield manufacturing process. In another nonlimiting embodiment, the connector is soldered to the electrically conductive arrangement during the annealing of glass blanks following the heating and shaping of the glass blanks. Soldering the leads during the annealing or laminating process eliminated possible thermal damage to the sheet by having the sheet heated during the soldering operation instead of only a small surface portion of the sheet at and eliminates the cost of a separated soldering operation.
Abstract:
The invention relates to a method for the sealed welding of a first element, made of a first material, to a second element, made of the first or of a second material, using ultrasound, wherein an intermediate element is disposed between the first element and the second element in an area to be connected and sealed and then ultrasonic oscillations are transmitted by way of a sonotrode. To ensure that the desired sealing weld connection can be provided even in areas in which the intermediate element and/or the first and/or the second element partially overlap, it is proposed that the intermediate element used is one that comprises perforations that are open both toward the first element and toward the second element, said perforations being filled with the material of the intermediate element during welding, at least in areas.
Abstract:
A hermetically sealed multi-pane window assembly comprises first and second windowpane sheets formed of transparent materials. A first sealing member has an inner edge and an outer edge, the inner edge being hermetically attached around the periphery of the first windowpane sheet by diffusion bonding. A second sealing member has an inner edge and an outer edge, the inner edge being hermetically attached around the periphery of the second windowpane sheet by diffusion bonding and the outer edge being hermetically attached to the outer edge of the first sealing member. A spacer assembly is disposed between the first and the second windowpane sheets for maintaining a gap therebetween, whereby a hermetically sealed cavity is defined between the first and the second windowpanes.

Abstract:
Verfahren zum Verbinden von Teilen aus nicht oder nur schwer mittels Zinnbasislot zu lötenden Werkstoffen miteinander oder mit Teilen aus leicht zu lötenden Werkstoffen, dadurch gekennzeichnet, dass zumindest auf zu verbindende Teilbereiche aus nicht oder nur schwer zu lötenden Werkstoffen eine oder mehrere metallische Haftschichten aufgebracht werden, wobei eine der Haftschichten eine oberste Haftschicht ist und zumindest die oberste Haftschicht mit Zinnbasislot gelötet werden kann.
Abstract:
Die Erfindung bezieht sich auf ein Verfahren zum abdichtenden Verschweißen eines ersten Elementes aus einem ersten Material mit einem zweiten Element aus dem ersten oder einem zweiten Material mittels Ultraschall, wobei zwischen dem ersten Element und dem zweiten Element in zu verbindendem und gegeneinander abzudichtendem Bereich ein Zwischenelement angeordnet wird und anschließend Ultraschallschwingungen über eine Sonotrode übertragen werden. Um sicherzustellen, dass auch in Bereichen, in denen das Zwischenelement und/oder das erste und/oder das zweite Element sich abschnittsweise überlappen, die gewünschte dichtende Schweißverbindung zur Verfügung gestellt werden kann, wird vorgeschlagen, dass als Zwischenelement ein solches verwendet wird, das sowohl zu dem ersten Element als auch zu dem zweiten Element hin offene Durchbrechungen aufweist, die während des Verschweißens zumindest bereichsweise mit Material des Zwischenelementes ausgefüllt werden.
