IPC: G03B7/099
Filed: 1991-12-19
Abstract: La présente invention décrit une pluralité d'éléments photosensibles disposés dans une configuration symétrique autour d'une région circulaire centrale. La région entourant la région centrale (12) est formée d'une zone carrée (14) ayant la région circulaire (12) en son centre et étant divisée en quatre quadrants égaux (14a-14d). La région suivante (16) est de forme rectangulaire et entoure la deuxième région. La région rectangulaire est formée de quatre sections égales, chacun des coins de la zone carrée se situant le long de deux bords adjacents des régions rectangulaires. Un moyen de sélection est prévu pour choisir le signal de sortie à partir d'une combinaison quelconque d'au moins deux des photodiodes de manière à accentuer la sensibilité du luxmètre à une zone ou caractéristique choisie de l'image à photographier.

Abstract: L'invention se rapporte à un compresseur rotatif dans lequel du 1,1,1,2-tétrafluoroéthane est utilisé comme réfrigérant et de l'ester de polyol, compatible avec ledit réfrigérant, est utilisé comme huile. Dans ce compresseur, on prévoit un cylindre composé d'un matériau à base de fer et une aube constituée d'un matériau à base d'aluminium composite contenant du carbone, et on prévient la corrosion du cylindre et/ou de l'aube qui pourrait être due à l'hydrolyse de l'huile à base d'ester de polyol, en limitant la production de chaleur par frottement glissant entre le cylindre et l'aube, réduisant ainsi le risque d'usure du cylindre et/ou de l'aube.

Abstract: Un procédé et un dispositif permettent de séparer des mélanges de particules diélectriques microscopiques en suspension. Les procédés connus de séparation effectuent la séparation de mélanges de particules selon la mobilité des différents éléments. Par conséquent, des mesures importantes de suppression de la convection dans la suspension doivent être prises. Selon le procédé décrit, le mélange de particules est entraîné sur des pistes par des forces diélectrophorétiques ou par l'écoulement du milieu de suspension. Une force supplémentaire, qui compense dans le cas de types déterminés de particules la force qui entraîne les particules sur les pistes, sépare les particules de ces types du mélange de particules. Le dispositif de mis en oeuvre de ce procédé se prête à l'intégration de systèmes. Il peut être intégré de manière économique et en grandes quantités sur la surface de galettes de silicium. Ce dispositif est utile pour isoler de petites particules telles que cellules biologiques, organelles de cellules, biomolécules et particules diélectriques organiques.

Abstract: Une structure d'éclairage creuse (42) comporte une surface lumineuse (44) qui transmet la lumière par des moyens optiques. Cette structure renferme au moins un guide de lumière (36, 38, 40). Une source lumineuse (30, 32, 34) émet de la lumière dans ce guide, dont la transmissivité lumineuse varie selon la position sur la surface du guide de lumière, de manière que la répartition angulaire et spatiale de la lumière qu'il transmet prédétermine la répartition de l'intensité lumineuse selon les différents points de la surface lumineuse. Cette répartition prédéterminée de l'intensité lumineuse se révèle de préférence pratiquement uniforme en tous points de la surface lumineuse.

Abstract: Oxidation of ammonium ions and organic carbon in ammonium-ion-containing and organic carbon-containing waste waters (effluents) by nitric acid at 100 to 350@C, in that the molar ratio of organic carbon to ammonium nitrogen is established at a range of 0.3:1 to 4:1 by addition of organic carbon or ammonium nitrogen. In a preferred embodiment which is reproduced by way of example in the figure, the waste water, which can be enriched, depending on the TOC content, with organic carbon, is transported via the feedline (1), possibly from an intermediate tank (2), by a pump (3) through a heat exchanger (4) in which it is preheated to, for example, 270@C. The preheated waste water is then heated by direct feed of 100 bar high-pressure steam via feedline (5) or by indirect heating to 290@C. After establishing the nitric acid concentration necessary for the ammonium degradation, e.g. via a feedline (6) in the waste water at 290@C, this is conveyed through a reactor (7) without back-mixing (e.g. a tubular reactor having internals and which is clad with titanium). After a residence time of, for example, 5 to 10 min, the reaction solution is cooled in counter-current with the feed and is depressurised in a separator (8). The waste water is removed via a line (9), via an intermediate tank (10) and a heat exchanger (11). <IMAGE>
