Patent EP-0469126-A1 (EP)
Inventor: WALKER ROBERT GRAHAM
IPC: G02B6/34
Filed: 1991-02-20
Abstract: On décrit un duplexeur optique à ondes guidées, comportant un duplexeur à quatre ports et caractérisé par le fait que la lumière d'une première longueur d'onde et polarisation est introduite dans le port 1 et pour sa plus grande partie est acheminée vers le port 2 (le reste vers le port 4), tandis que la lumière d'une deuxième longueur d'onde et polarisation est introduite au port 2 et pour sa plus grande partie est acheminée vers le port 3. L'invention concerne des moyens permettant d'empêcher la lumière de la première catégorie, réfléchie d'une interface au-delà du port 2, d'atteindre le port 3. La technique utilisée fait intervenir l'effet interférométrique de la lumière réfléchie du port 2 avec celle de la sortie complémentaire au port 4, ce qui ne nécessite qu'un simple décalage de phase de 90° entre ces sorties à l'interface de réflexion. Ce but est atteint soit en positionnant l'interface à un angle donné ou en utilisant des guides d'ondes courbés.

Abstract: L'invention concerne un procédé et un dispositif pour détecter des substances (A, B) dans une substance ambiante, en particulier pour détecter des agents chimiques de combat dans l'air ambiant. Selon ledit procédé, des ions de réaction légers (O2-, H+ avec des groupes H2O) sont générés dans une substance de réaction (air ambiant, H2O) et ajoutés au mélange se composant de la substance (A, B) et de la substance ambiante. Des ions de réaction (O2-, H+ avec des groupes H2O) se déposent dans une chambre de mesure (10) en une répartition spatialement non uniforme de molécules lourdes (MA-, MB+) de la substance (A, B) pour former des ions de quasi-molécules (MA-, MB+). Un champ électrique à variations dans le temps de fréquence de base et d'amplitude prédéterminées, qui alterne autour d'une ligne zéro, est généré dans la chambre de mesure (10). Le courant d'ions de quasi-molécules dû au champ électrique est mesuré et le signal de mesure obtenu est évalué. Pour distinguer une première substance (A) d'une seconde substance (B) présentes au même moment dans la substance ambiante, unessai préliminaire est d'abord exécuté pour une chambre de mesure définie (10) afin de déterminer la dépendance du courant d'ions de quasi-molécules par rapport à la fréquence de base, et à la fois l'amplitude et l'asymétrie de la variation dans le temps de l'intensité du champ électrique autour de la ligne zéro sont déterminées, de façon séparée, pour la première (A) et la seconde (B) substances. Une première mesure concernant le mélange (32) est alors effectuée au niveau d'une première asymétrie, cette mesure étant suivie d'une seconde mesure relative audit mélange (32), au niveau d'une seconde asymétrie. Les signaux de mesure résultant de ces deux mesures sont combinés logiquement.

Title: Procede et appareil pour transfert simultane monocanal de chaleur et de masse
Inventor: ALBERS WALTER F
IPC: F24F3/14
Filed: 1991-10-22
Abstract: Sont décrits un procédé et un appareil pour le transfert de chaleur et de masse s'appliquant à la régénération de solutions déshydratantes de liquide, le thermopompage de gaz humides, le refroidissement et la déshumidification de gaz pour la climatisation, et l'absorption d'eau dans l'air. Généralement, à l'aide d'un gaz en mouvement (12), à une pression constante, une variation continue d'un équilibre vapeur-liquide est créée entre des températures, proches mais variant continuellement, de déshydratants de liquide et de gaz, à l'intérieur d'une chambre de transfert d'énergie. L'humectage de la chambre, effectué de manière segmentée (38, 40, 42) permet un transfert de masse dans et depuis le gaz en mouvement. Un différentiel de température forcé entre des puits (62) et des sources thermiques (72) provoque le transfert de chaleur au moyen de barrières thermoconductrices. Simultanément, avec les écarts de température, l'humectage segmenté permet également la variation, entre les secteurs humectés (38, 40, 42), des concentrations de déshydratants (44) de liquide provoquées par l'évaporation ou la condensation. Un mouvement migratoire reliant ces secteurs humectés permet le développement de gradients de concentration applicables entre les secteurs humectés sur la longueur de la chambre.

Abstract: In a speech signal transmitting system which effect VOX control, the transmitting side transmits a postamble and the succeeding background noise coded data at regular time intervals in a silent duration subsequent to a speech-active duration. At the receiving end, upon each reception of the background noise coded data in the silent duration, power information and prediction coefficients contained in the coded data are stored in a background noise parameter memory (22). A random pattern, generated by a random pattern generator (23), is used as a residual signal, and a background noise is synthesized by a background noise synthesizer (24) on the basis of the power information and prediction coefficients read out of the background noise parameter memory for each frame. In the speech-active duration a decoded speech is output, and in the silent duration the synthesized background noise is output.

Abstract: The pipe coupling has a housing (10) which can be constricted and in which the elastomer sealing collar (32) is arranged which has a C-shaped cross-section and sealing lips (36) extending towards one another. The meandering spring ring (44) which has a U-shaped cross-section and is provided with slots (74) is inserted into the respective annular groove (42) in order to support the sealing lip (36) on the collar web (34). When the housing (10) is constricted, the collar (32) is compressed in the circumferential sense and the sealing lips (36) rest smoothly on the pipe wall (55). At the same time, the spring ring (44) is constricted by the width of the slots (74) being reduced. The sealing lip (36) is supported by the spring ring (44) over a large area and the material of the collar (32) is prevented from flowing into and through the slots (74). The spring limb (68) which projects beyond the sealing lip (36) prevents the annular bead (56) sticking to the collar web (34). This pipe coupling is particularly suitable for use in the case of high operating temperatures and large temperature changes.

Abstract: The invention is directed to a gas permeable well nozzle for use in a metallurgical vessel such as in a well block of a tundish, ladle or like vessel. The well nozzle (40) is generally cylindrical in shape and includes a gas permeable refractory member (42) having an axial bore (44) therethrough. The gas permeable member is preferably formed of a pressed and fired ceramic refractory material having a high resistance to molten metal erosion such as alumina, zirconia or magnesia, present either as a single phase or as a carbon bonded system. A castable refractory member (46) is positioned around the outside of the gas permeable portion and defines an open gas annulus (48) therebetween. The castable portion contacts the gas permeable portion to form upper and lower gas impermeable joints around the gas annulus. A metal can (50) is preferably positioned around the castable member and includes a gas fitting (52) which communicates with a gas inlet channel (49) formed in the castable portion to permit introduction of pressurized inert gas therethrough. The major refractory constituents of the gas permeable member and the castable member are preferably identical so as to provide matched thermal expansion rates and thus lessen the opportunity for thermal induced cracking along the gas impermeable joints between the two members.
