Inventor: KARHU NIILO VILHELM
IPC: E05D15/36
Filed: 1988-12-08
Abstract: La présente invention se rapporte à un vitrage pivotant pour balcon. Les vitrages de balcon connus comprennent quatre vitres ou davantage, lesquelles se déplacent en se chevauchant sur deux voies adjacentes. Une telle installation nécessite la pose de structures imposantes faites de joints étanches et d'encadrements, ce qui nuit à l'aspect extérieur de la construction. En outre, l'ouverture du balcon peut être ouverte à 50 % au maximum et il est difficile de laver les surfaces externes des vitres. La présente invention élimine ces désavantages grâce à la disposition de toutes les vitres adjacentes dans la même voie à deux rails. Sur le bord supérieur de chaque vitre mobile (1) sont diposés deux patins (3, 4) dont l'un se déplace sur un rail externe droit et l'autre sur un rail interne incurvé vers l'intérieur et en direction de la paroi latérale (13) du balcon. A l'intérieur de la partie incurvée (18) du rail interne, le bord arrière de la vitre est tourné vers l'intérieur et la vitre peut être ouverte contre la paroi latérale (13) du balcon. Ainsi, il est possible de déplacer une ou plusieurs vitres hors de l'ouverture du balcon. Les vitres peuvent également pivoter à 180°, ce qui permet de faire tourner une surface thermo-réfléchissante (19) pour l'orienter vers l'extérieur ou vers l'intérieur, selon les besoins. Des patins coulissant sur la voie inférieure sont disposés sur le bord inférieur de la vitre et l'un des patins sort de la voie lorsque la vitre est tournée vers l'intérieur.

Abstract: Le procédé et l'appareil décrits (10) servent à déterminer de façon non destructive la fraction volumique et la porosité respectivement des fibres et de la résine constituant un matériau composite fabriqué à base d'au moins deux matériaux constitutifs différents. Les paramètres suivants du matériau composite à tester sont connus: la densité, les modules d'élasticité des matériaux constitutifs et la séquence de superposition des couches. Ledit procédé consiste à propager deux ondes acoustiques de polarisations différentes à travers le matériau composite, à détecter les ondes acoustiques propagées à travers le matériau composite (14, 100, 16, 104) et à déterminer la vitesse de chacune des deux ondes acoustiques, V1 et V2. L'épaisseur du matériau composite est déterminée. La fraction volumique et la porosité respectivement des fibres et de la résine constituant le matériau composite sont ensuite déterminées sur la base des vitesses, V1 et V2, de l'épaisseur et des paramètres connus relatifs à la densité, aux modules d'élasticité des matériaux constitutifs et à la séquence de superposition des couches.

Filed: 1990-12-14
Abstract: The invention relates to a sol-gel method for forming a metal oxide film, e.g. TiO₂ film or TiO₂-SiO₂ film, on a substrate by applying a solution of at least one metal alkoxide to the substrate to form a sol film on the substrate, drying the sol film to cause it to turn into a gel film by hydrolysis and baking the gel film. According to the invention the viscosity of the metal alkoxide solution is adequately increased, preferably to 3-30 cP at 20°C, by the addition of a combination of a hydroxypropyl cellulose of which 2 wt% aqueous solution has a viscosity of 150-400 cP at 20°C and another hydroxypropyl cellulose of which 2 wt% aqueous solution has a viscosity of 6-10 cP at 20°C. Metal oxide films formed by this method are free from minute cracks and excellent in optical characteristics and durability. By this method it is possible to form a metal oxide film as thick as about 300 nm without repeating the application of the alkoxide solution to the substrate.

Abstract: The valve assembly for non-returnable packing comprises a valve housing including a main valve and an auxiliary valve the latter being initially kept in opened position through a resilient locking device which is unlocked, at the end of a first filling through a displacement of the main valve beyond its position of normal opening under the action of a long travel filling tap. The auxiliary valve is then forced to rest on its seat by means of a spring with low calibration. Any depression caused by tapping would provoke the opening of the auxiliary valve, while any overpressure resulting from filling would hit the auxiliary valve in a closed position.
