Abstract: Selon un procédé d'optimisation de la combustion de carburants avec des émissions minimales de CO, on introduit au préalable dans le mélange air-carburant un brouillard d'un liquide contenant de l'eau et/ou de l'alcool et on génère un mélange homogène de liquide et de carburant. L'invention concerne en outre un dispositif de mise en ÷uvre de ce procédé. Afin d'économiser des quantités considérables d'essence et de réduire les émissions de monoxyde de carbone, on ajoute au mélange air-carburant un brouillard d'un liquide dans un champ d'écoulement turbulent afin d'obtenir des gouttelettes de carburant d'un volume aussi réduit que possible et de les maintenir en existence jusqu'à la combustion. A cet effet, un pulvérisateur de liquide introduit par doses des gouttelettes de liquide dans une chambre de tourbillonnement du pulvérisateur, où ces gouttelettes pénètrent dans le mélange de carburant ou air-carburant. Le brouillard de liquide se compose en grande partie d'eau distillée, à laquelle est ajouté un acide organique faible peu concentré, et d'alcool, ou d'un mélange de parties égales d'eau, de méthanol et de quantités minimes de glycérine d'une part et d'un mélange de méthanol et d'huile d'autre part.

Abstract: A method of producing component parts of a fluid chamber wherein the peripheral portion of a steel plate (1) held by a pair of rotary molds is thickened using a roller prior to and for the purpose of forming a seal ring groove (14) in the outer peripheral surface of the steel plate having a circular outer peripheral edge. After a preliminary thick portion (11) is formed along the peripheral edge of the steel plate, a main thick portion (12) is formed along the outer peripheral surface of the steel plate, the main thick portion (12) having a thickness large enough to form the seal ring groove. Thereby, the steel plate is prevented from buckling under the pressing force imparted by the roller during the formation of the main thick portion.

Abstract: Starting point: The sequence is known of a copying switching matrix, a distribution switching matrix and a destination switching matrix on the one hand, and on the other hand a switching matrix in which copying can be carried out in every stage. 
<??>Technical problem: Real operation is a mixture of point-to-point connections, point-to-multipoint connections with few branches and point-to-multipoint connections with many branches. The overall traffic and its individual constituent parts are constantly changing. The known structures are optimised in each case for one specific traffic type in one direction only. 
<??>Fundamental concept: The switching elements of a switching matrix which is optimised for point-to-point connections contain the additional facility for copying a small number of input signals for any number of outputs, whereby a very large number of copies can be achieved overall for a very small number of input signals. This switching matrix is supplemented by a copying switching matrix, which serves solely to produce in each case a limited number of copies for a large number of input signals, which are then switched in the (main) switching matrix as point-to-point connections. 
<??>Solution: Point-to-point connections are operated as "connectionless connections" by means of automatic switching element control. It is ensured that these connections act outwardly as virtual connections. Point-to-multipoint connections are also operated in the main switching matrix as virtual connections (connection-oriented) by means of connection tables. 
<??>Advantage:Interference-free rearrangement of existing virtual connections possible. Very even utilisation of the (main) switching matrix as a whole. 
<??>Disadvantage: Switching elements with two different addressing facilities required.

Abstract: A high opacity, defined kaolin clay product having a relatively narrow particle size distribution, low colloidal particle content and an average particle surface area of less than about 30 square meters per gram is prepared by defining an aqueous kaolin clay slurry via controlled centrifugation to remove a substantial portion of the colloidal particles therein. Prior to being subjected to centrifugation, the aqueous kaolin clay slurry is prepared so as to improve the defining process achieved via centrifugation by first subjecting the aqueous kaolin clay suspension to scrub grinding so as to break up agglomerates into individual kaolin clay particles without substantial delamination of the kaolin clay particles. Thence, the mechanically dispersed kaolin clay suspension is dispersed well by the addition of a chemical dispersant, most advantageously sodium hexamethaphosphate, and dilution water is admixed into the aqueous kaolin clay suspension to reduce the solids content thereof to a level less than at least about 18% solids by weight, and preferably to about 5% to about 15% by weight, prior to centrifugation.

Abstract: L'invention se rapporte à un appareil et à un procédé associé qui permettent de déterminer l'espèce lumineuse dominant en un lieu, cet appareil étant plus fiable et plus précis que les détecteurs d'espèces lumineuses de la technique actuelle. Une fonction de détection d'espèces lumineuses mélangées est ajoutée au choix des catégories d'espèces lumineuses, pour prendre en considération les cas où aucune espèce lumineuse seule n'est dominante et où c'est au moyen d'algorithmes d'impression qu'on peut obtenir la meilleure gestion des opérations de correction de couleur. De nouvelles conditions limites ont été mises au point pour éliminer les erreurs de détection qui apparaissent lorsqu'un mélange entre des sources lumineuses fluorescentes et certaines quantités de lumière du jour induit l'appareil à lire qu'il s'agit d'un éclairage au tungstène. Dans l'appareil est incorporée une fonction de seuillage, qui constitue une amélioration par rapport à la technique actuelle. L'appareil se compose d'un organe permettant de convertir le rayonnement lumineux en signaux électriques correspondants. Les signaux électriques sont ensuite dirigés vers un amplificateur logarithmique où ils sont comprimés pour former approximativement un signal possédant un terme égal au logarithme du terme de courant continu plus un rapport entre les composantes de courant alternatif dominantes et les composantes de courant continu. Une autre partie de l'appareil reçoit les signaux provenant de l'amplificateur logarithmique et fournit à la sortie deux résultats filtrés qui sont des multiples de la fréquence des sources lumineuses artificielles prévues. Chacun des signaux de sortie est comparé à plusieurs signaux de seuil pour permettre d'identifier quelles composantes d'espèces lumineuses sont présentes. La combinaison des composantes détectées est ensuite comparée aux composantes des sources lumineuses connues, la correspondance la plus étroite permettant d'identifier la source inconnue. Un organe est prévu pour combiner les signaux de sortie provenant des deux filtres, ce qui permet d'identifier les sources mélangées.

Abstract: Un détecteur de rotation à fibre optique possédant une paire de faisceaux lumineux en contre-propagation dans une boucle comprend un modulateur de phase destiné à moduler les ondes à une première fréquence. Lorsqu'elles quittent la boucle, les ondes se rassemblent pour former un signal d'intensité lumineuse indicateur de la vitesse de rotation et détecté. On déphase en quadrature un signal à la première fréquence par un signal de fréquence inférieure, puis on l'additionne au signal de vitesse détecté. Un amplificateur amplifie les signaux additionnés et provoque également et de manière inhérente des déphasages indésirables et égaux à la fois dans le signal de vitesse détecté et dans le signal en quadrature. On démodule le signal en quadrature et on l'utilise en retour pour réguler la phase d'un déphaseur variable qui produit un signal à la première fréquence dont le déphasage est égal au déphasage indésirable du signal de vitesse détecté, ce dernier signal étant envoyé conjointement avec le signal du déphaseur variable à un démodulateur apte à démoduler les informations de vitesse de rotation à partir du signal de vitesse détecté.
