Abstract: The invention relates to a door, a fanlight, door side section (door side light), window or similar, characterised by two glass sheets arranged beside one another at a distance, by a frame holding the sheets at a distance from one another--preferably incorporating fittings for the door etc., said frame essentially being covered by the sheets, by sealing means for the hermetic sealing of the space enclosed by frame between sheets and by a dessicant communicating with this space.

Abstract: This invention relates to a mechanism or hinge for use in a structural glass assembly. In particular the mechanism is attachable to a glass unit, e.g. a double glazing unit, to enable it to open or close. The mechanism has essentially two parts, a stationary part and a movable part. The stationary part which is attachable to the glass structure incorporates two blade-like plates between which the movable part is slideably located. The stationary part has two arcuate tracks (open and closed) over which a pair of roller bearings are guided during operation of the mechanism whereas the movable part which is attachable to e.g. a double glazed unit, has a single arcuate track over which a single roller bearing is guided during operation of the mechanism. The mechanism has a virtual pivot point on the glazing unit to which the mechanism is attachable. One embodiment of the invention includes a centring arrangement FIG.
