Abstract: The invention concerns a method for producing a pattern on a transparent substrate, particularly a glass or glass-ceramic substrate. According to the invention, there is deposited on at least one area of one face of the substrate, a first layer of a photosensitive resin comprising at least one sensitizing agent and at least one photosensitive compound essentially composed of a polymer with an average degree of cross-linking d° such that it is able to absorb solid particles. Certain areas of said first layer are exposed to light, particularly in order to increase, in a controlled manner, the average degree of cross-linking d° of said polymer so as to modulate its absorption capacity. On the first layer is deposited at least one second layer of a mineral-particle-based composition. The substrate is subjected to at least one treatment cycle, particularly in order to fix said mineral particles. The invention also concerns the substrate produced by this method and its applications.

Abstract: A rebuildable radial lip seal having a replaceable sealing element for sealing around a movable shaft and adapted for removable placement within a seal housing. The rebuildable radial seal comprises an annular sealing body which extends radially between an annular inner seal surface and an annular outer seal surface. The inner seal surface defines a first inner diameter and includes a circumferential rib which protrudes radially inward from the inner surface. An annular end flange is coaxially engageable with the seal body. The end flange includes a coaxially protruding annular rim which is engageable within the first inner diameter of the seal body to form a circumferential inner slot between the circumferential rib and the inner surface of the seal body and the annular rim on the end flange. An annular sealing element having an inner sealing lip is sealably captured within the inner circumferential slot formed between the seal body and the end flange.

The panels have a lining on the side of the flow channel of the duct and on at least one part of at least one of transverse edges of the duct.

Abstract: A fire-resistant glazing panel comprises at least two glass sheets, between which is placed a transparent fire-resistant material made of a cured alkali metal polysilicate hydrate. At least one glass sheet is provided, on its surface which is in contact with the fire-resistant material, with a primer layer, the adhesion of which to the fire-resistant layer decreases at the temperatures of the test of behaviour towards fire. At the temperature of the test of behaviour towards fire, the glass sheet exposed to the fire separates completely from the fire-resistant material. For this reason, the polysilicate fire-resistant shield remains intact, even when the glass sheet exposed to the fire shatters and when the fragments fall off.

Abstract: The invention relates to a unit with variable optical properties, which combines at least one system with variable light transmission/absorption, especially of the electrochromic or viologen type, with at least one system with variable light diffusion, especially of the optical valve type or with liquid crystals. The systems are electrically control-driven in order to modulate in a decorrelated manner the light transmission level and the light diffusion level of the unit.

Abstract: This invention relates to an all-ceramic bearing having wherein the fracture toughness and hardness values of the rings and roller elements are adjusted to produce pseudo-plastic contact, high resistance to roller contact fatigue and high resistance to wear.

Abstract: The only methods hitherto available for the production of mineral wool from materials such as basalt either utilize a stationary nozzle (blast drawing method) or external centrifuging whereby unsatisfactory yield and/or a not entirely satisfactory fiber quality, particularly with regard to a high content of unfiberized components, are achieved. By way of the invention, application of a fiberization method is suggested which, in spite of a high fluidity of the molten mineral material such as basalt, arrives at high quality fibers with a low bead proportion at good yield. This is made possible by selection of specific materials and their fiberization in specific conditions. Whereas fiberization of these fluid materials is carried out in external centrifuging at viscosities of a few tens of poises, fiberization by internal centrifuging at viscosities of more than 100 poises is required, according to the: invention, in order to achieve a mineral wool for insulation purposes with a low bead content.

Abstract: The invention relates to a process for bending glass sheets. This process involves bending the glass sheet or sheets in at least two stages. The first stage employing the action of gravity leading to a shaped blank which is used in the formation of the final shape. The last stage which leads to the final shape, involves the simultaneous or nonsimultaneous, combined actions of gravity and at least one additional mechanical force. The invention also includes a bending apparatus providing at least one section having two separately useable parts with one of the parts being movable with respect to the other to permit the section to be arranged in one of two positions. In addition, the invention includes bent glazing having at least one docking angle exceeding 50.degree. and a radius of curvature below 200 mm.

Abstract: There is disclosed a method for bending a sheet of glass heated to a bending temperature in a horizontal furnace through which it is conveyed by a plane conveyor delivering the glass sheet to a bending cell heated to substantially the same temperature as the bending temperature. A concave annular recessed portion moves the glass sheet vertically towards a solid convex projecting portion within the cell, so that the sheet is squeezed between the concave and convex portions. A device for carrying out the method and its use for producing glazing with a particularly complex shape are also disclosed.
