Abstract: For the manufacture of a glass substrate bearing a multicolor decoration or image consisting of inks(s) for firing, a model of the multicolor decoration or image consisting of ink(s) of any type is manufactured on a support which is suitable for these inks. By means of a reproduction device composed of an image-capturing device, image-processing software and a printing means, the model is transferred onto the sheet of glass using one or more inks for firing. The layer of ink is then fired.

Abstract: The invention relates to a method of processing an electrochemical device having at least one carrier substrate (1) provided with a stack (2) of functional layers, including at least one electrochemically active layer (4) which is capable of reversibly and simultaneously inserting ions and electrons and is arranged between two electroconductive layers, in particular a device of the electrochromic type. The processing consists in locally inhibiting the functionality of at least one of the functional layers, with the exception of one of the electroconductive layers (3, 8), so as to delimit an inactive peripheral region in the stack (2).

Abstract: The invention relates to a glass substrate having on at least one of its faces an antireflection coating formed by a stack of thin dielectric material layers having alternately high and low refractive indices. To prevent the modification of the optical properties of the coating in the case where the substrate is subject to a heat treatment such as tempering, bending or annealing, the layer or layers of the stack which are liable to deteriorate on contact with alkali ions such as sodium ions are separated form the substrate by at least one layer forming part of the antireflection coating and forming a “shield” with respect to the diffusion of alkali.

Abstract: A glazing assembly is provided made of at least one transparent substrate having a stack thereon that includes an alternation of n functional layers and n-1 coatings, wherein the functional layers have reflection properties in the infrared and/or solar radiation and where n≳1 and where, in order to maintain the quality of the stack when the substrate is subjected to a heat treatment step, at least one of the following must be satisfied: the coating placed on top of at least one of the functional layers includes at least one barrier layer providing a barrier to at least oxygen and water; and at least one absorbent or stabilizing layer made of a material capable of absorbing or stabilizing the consituent material of the functional layer forms a part of either the coating placed on top of the functional layer and under the barrier layer or the coating placed beneath the functional layer; and a method for production of the glazing assembly.

Abstract: The present document describes a process for manufacturing a pane of laminated glass without recourse to an autoclave. The pack of layers are composed of stacked layers (6, 7, 8), is raised to the softening temperature of the thermoplastic interlayer of the pack of layers in a preheat channel (1). The preheated pack of layers is put under vacuum in a vacuum assembly station (2) for the purpose of extracting the gas from the spaces separating the layers (6, 7, 8). After the gas has been extracted, the edge of the pack of layers, which is held under vacuum, is mechanically compressed inside the vacuum box and is thus sealed. Finally, the pack of layers is brought to atmospheric pressure and its temperature further increased in a postheat channel (4).

Abstract: A window with an aerial for motor vehicles is provided with an electrically conductive layer (5) which fulfils the function of an aerial conductor. In order to prevent capacitive coupling of the layer to the bodywork of the vehicle, the layer (5) ends at a distance of a few centimetres from the edge of the window. The layer (5) is coupled capacitively to the aerial connection cable leading to the receiver set by means of a coupling electrode (9). The coupling electrode comprises thin wires (10) which are connected together by electroplating and are arranged at a large distance from one another which is large compared with their diameter.

Abstract: A process for shaping glass sheets with a surface-shaping mould, against which the glass sheets are pressed using a pressure drop produced by sucking out the air from the space lying between the moulding face and that face of the glass sheet on the opposite side from the glass sheet, in which the pressure drop is a maximum at the edge of the glass sheet and decreases towards the center of the glass sheet, because of fact that air is introduced via air-inlet apertures opening into the moulding face, the air is again extracted by subjecting suction apertures made in the moulding face inside the region covered by the respective glass sheet to a vacuum. Furthermore, pressure between the glass sheet and the moulding face also in the region where the air is introduced is set to a value at most equal to the pressure beyond the glass sheet, in order to avoid any formation of bulging. A shaping mould suitable in particular for implementing this process is also described.

These panes, having such an antenna, are used for the reception and transmission of frequencies higher than 1 GHz and preferably for the frequency bands 5795-5815 MHz, 63-64 GHz and 74-77 GHz.

Abstract: In a contact device for an electrical functional element, for example an antenna, disposed on a window, in particular on a vehicle window, with a housing fixed on the window and comprising electrical components, such as an amplifier, with an input connection between the housing and the functional element, which is also fixed on the window, and with output links in accordance with the invention, the input connection (104; 204) is, in two different variants, each time surrounded by an adhesive layer, independently of its placement in electrical contact; in one of the variants, it is disposed outside the housing (102), in the other variant it is overlain by the housing (202). The electrical contact to the functional element is effected during or after bonding the housing and respectively the input connection, preferably by soldering, so as to ensure particularly reliable placement in contact.
