摘要:
Glasses with a determined, precise surface structuring are required in the area of glasses which have optic functions, for example, in display panels of new generation flat display screens, so-called channel plates. While avoiding the disadvantages of prior art screen printing technology, the invention provides a shaping tool (1) which has a structured surface for producing structures on glass (2) and which makes it possible to economically form highly precise microstructures by locally heating the glass region to be structured. The inventive shaping tool comprises a rolling cylinder (3) with a metallic hollow cylinder (7), a shaping sheet metal (8) fixed on the surface of said hollow cylinder, and a traversing shaft (5) for continuously driving the rolling cylinder (3) via drive elements (4). An electric heater is arranged in an electrically insulated manner between the shaft (5) and the hollow cylinder (7).
摘要:
L'invention propose un vitrage diffusant la lumière. Il s'agit d'un verre laminé à chaud, l'empreinte imprimée dans le verre étant constituée de cratères pyramidaux séparés les uns des autres par des distances inférieures à leur plus grande dimension. Dans une variante, des plages non diffusantes sont insérées à cotés des zones diffusantes. Le procédé et le dispositif pour réaliser le vitrage diffusant font également partie de l'invention.
摘要:
Vitrage destiné à l'éclairage des locaux et en particulier des serres. La transmission directe de la lumière est croissante du bas vers le haut de la paroi. Cette variation est obtenue soit par modification de la transmission spectrale soit grâce à une structure diffusante. Le vitrage permet d'avoir l'éclairage maximum avec des contrastes ombre-lumière qui restent supportables.
摘要:
The present invention is directed to a method for forming glass articles containing enclosed channels. The method comprises the flollowing steps: a) delivering and depositing a first length of a molten glass ribbon (18) to a surface of a mold (20) having a modl cavity (22) possessing at least one channel-forming groove (22) and a peripheral surface, wherein the first length (18) overlies the mold cavity (22) and the peripheral surface; b) allowing the first length of the molten glass ribbon (18) to substantially conform to the contour of the mold cavity (22) resulting in the formation of at least one channel in the first length of the molten glass ribbon (18); c) delivering and depositing a second length of the molten glass ribbon (26) to the exposed surface of the first length of the molten glass ribbon (18). The delivered molten glass viscosity of the molten glass ribbon (18, 26) is such that the following is achieved: 1) the second length (26) bridges but does not sag into complete contact with the channel portion of the earlier-deposited first length (18); and, 2) a hermetic seal is formed wherever the molten glass' first (18) and second lengths (26) contact.
