Methods systems and apparatuses for reducing or substantially eliminating distortion in a transparent substrate in situ are disclosed.

A method for producing a laminated glass with a resin frame includes a disposing step of disposing a laminated glass inside a shaping mold in which a cavity into which a resin material for a resin frame is injected is formed, an injection step of injecting the resin material into the cavity from a first surface side of the laminated glass or an end face side of the laminated glass, a blocking step of blocking a flow of the resin material in at least a part of a peripheral portion of the laminated glass to prevent the resin material from reaching an outer peripheral region on a second surface opposite to the first surface, and an opposing force applying step of applying an opposing force from an opposing force applying position on the second surface and inside of the outer peripheral region of the laminated glass.

An object is to provide a daylighting sheet which efficiently performs daylighting and in which, when the daylighting sheet is applied to a window of a building or the like, it is possible to see an outdoor side.

The daylighting sheet includes a translucent base material layer; and a light deflection layer that is formed on the base material layer, and the light deflection layer includes: light transmission portions that are aligned along one surface of the base material layer so as to be able to transmit light, each of which including a groove at a portion being in a light entering side in a position where the light transmission portion is arranged in the opening portion of a building; and light deflection portions that are formed between the light transmission portions and filled with a material whose refractive index is lower than that of the light transmission portions.

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered to the inner surface of the body ply and has a portion extending across the aperture, forming a window into the container. The method involves providing a window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device that is adapted to release pressurized air into the container through at least one of the platens. The container is engaged between the platens in an airtight manner and, optionally, the container window is positioned adjacent the inside wall of the machine pocket. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

The process for the manufacture of windows/doors (1), characterized by the fact that it comprises the following steps: providing at least one inner panel (2) for windows/doors; providing a plurality of plastic profiled elements (3) for windows/doors, each of the profiled elements (3) comprising at least two areas to seal (5), coupleable to the areas to seal (5) of the other profiled elements (3), and at least one longitudinal slot (6), in which a respective perimeter side (4) of the inner panel (2) is insertable; performing a step of mechanical machining by chip removal on at least one of the areas to seal (5); heating the areas to seal (5); coupling the heated areas to seal (5) to one another by pressing the profiled elements (3) one against the other to maintain the areas to seal (5) in mutual contact and define the frame for windows/doors, the coupling taking place with the inner panel (2) inserted in the longitudinal slots (6) to define a window/door (1) which is composed by the frame and by the inner panel (2) contained in the frame.

A flame-retardant composite glass including a plurality of glass panes and a flame-retardant intermediate layer that is arranged between two first glass panes and includes a flame-retardant material that foams or swells up in the event of a fire, as well as an attack-resistant layer having a transparent plastic that is solid at room temperature. The flame-retardant composite glass has, between the first glass panes, an edge compound extending along and around the edges such that a chamber filled with said flame-retardant material is defined by the first glass panes and the edge compound. Between at least one of the first glass panes and the flame-retardant material, a primer layer is arranged that includes a material whose adhesion to the flame-retardant intermediate layer and/or to the glass pane becomes weaker in flame-retardant test conditions than it is in room temperature conditions.

A method of bonding a metal fitting to a polyurethane structure, the method comprising abrading a surface of the metal fitting with an abrasive; cleaning the metal fitting with a solvent; cleaning a surface of the polyurethane structure with an alcohol; applying a primer to the surface of the metal fitting; applying an adhesive to the surface of the metal fitting and the surface of the polyurethane structure; applying a liquid polyurethane compound to the surface of the metal fitting and the surface of the polyurethane structure; and pressing the surface of the metal fitting against the surface of the polyurethane structure to form an assembly. The primer can comprise a first resin and a first catalyst in a ratio of about 1.1 to 1; the adhesive can comprise a second resin and a second catalyst in a ratio of about 3 to 1; and the liquid polyurethane compound can comprise a third resin and a third catalyst in a ratio of about 10 to 1.
