Patent EP-0112943-A1 (EP)
Inventor: HOLLOWAY CHRISTOPHER
IPC: H04L9/18
Filed: 1982-12-30
Abstract: A data communication network in which binary coded sensitive data is transmitted between locations through a message switching node. At the originating location the sensitive data is exclusively OR'd (XOR) with an origin message key to produce a first coded message. At the message switching node the origin message key and a destination message key are XOR'd and the result XOR'd with the first coded message to produce a second coded message. At the destination the destination message key is XOR'd with the second coded message giving the binary coded sensitive data. The invention finds particular use in an EFT network.

Abstract: On forme des corps de boites (32) a partir d'une tole d'acier lamine a froid revetue d'une fine couche d'un alliage nickel-zinc formee par electro-deposition sur au moins un cote. La tole d'acier ainsi revetue est etiree sous la forme d'une coupelle (31) revetue de nickel-zinc au moins sur sa surface externe et on etire sur un mandrin (42) la paroi laterale de la coupelle afin de diminuer son epaisseur et d'accroitre sa longueur. L'etirage sur mandrin de l'acier revetu de l'alliage (11, 92) est ameliore grace a l'utilisation d'un ensemble (50) comprenant une pluralite de matrices annulaires d'etirage (44, 46, 48), chacune de ces matrices presentant une surface d'entree generalement conique dont l'angle par rapport a l'axe d'etirage est dans la gamme se situant entre 6 a 8,5 environ et une partie centrale sensiblement cylindrique (80) dont la longueur n'excede pas environ 0,063 centimetres. La longueur de la partie centrale (80) de la matrice finale (48) n'est pas superieure a celle de l'une quelconque des matrices precedentes et peut lui etre inferieure et se situe de preference dans la gamme de 0,0075 a 0,018 centimetres environ. Le diametre de la partie centrale des matrices successives decroit progressivement dans le sens du mouvement d'une boite a travers l'ensemble de matrices, le diametre de la matrice finale etant tel que la paroi laterale de la coupelle penetrant dans cette matrice soit reduite d'environ la moitie.

Abstract: Un element optique holographique est utilise en tant qu'ecran de diffusion directionnelle. Des ecrans conventionnels de diffusion a verre depoli ne permettent pas de determiner la position de sortie de la pupille, laquelle pupille definit la zone de vision, independamment de l'eclairage d'entree, et une grande partie de cette energie d'eclairage incidente sur cet ecran de diffusion conventionnel est perdue parce qu'elle est dirigee vers des positions se trouvant a l'exterieur de la zone de vison. L'utilisation d'un element optique holographique (32) en tant qu'ecran de diffusion directionnelle permet de projeter des informations situees dans le plan focal (48) sur la pupille de vision (52). Au niveau de la pupille de vision (52), la distribution de l'eclairage est d'une uniformite selective et comprend sensiblement toute l'energie optique de diffraction pour obtenir une image ayant une meilleure brillance.

Abstract: Procédé de détection de molécules organiques et de biomolécules par des procédés de détection par sensibilisation des surfaces, les molécules se liant de manière covalente à la surface de test plane, solide qui a été modifiée chimiquement par un procédé de silanisation lui donnant des groupes réactifs appropriés et fonctionnels pour la liaison covalente. L'invention concerne une technique de silanisation qui combine une technique spéciale de nettoyage des surfaces à silaniser avec un procédé de silanisation à basse pression et avec le silane en phase gazeuse, la température des surfaces à silaniser étant augmentée. Le procédé donne des surfaces reproductibles pourvues de couches de silane fonctionnelles stables, homogènes et d'un caractère monocouche. Ces surfaces sont ensuite utilisées pour le couplage covalent de molécules organiques et de biomolécules hautement spécifiques sur les surfaces. Le couplage peut s'effectuer directement à l'aide d'un groupe réactif sur le silane ou à l'aide d'un agent de réaction de couplage bifonctionnel tel que par exemple N-succinimidyl-3-(2-pyridyldithio)propionate, le carbodiimide ou le glutardialdéhyde.

Abstract: An improved supercharger (10) of the Roots-type. The supercharger includes a three-piece housing assembly (14, 16, 18) defining generally cylindrical chambers containing two rotors (20, 22) having meshed lobes (20c, 22c) of modified involute profile which pump air from an unshown inlet to an outlet (56). The rotors are fixed to stepped diameter shafts (24, 26) pressed into centrally located through bores in the rotors. Straight splines (24e, 26e) on the shafts form mating splines in the rotor bores to prevent rotation of the shafts in the bores. Bearing assembly (28, 30) disposed at adjacent ends (20a, 22a) of the rotors support one end of the rotors in the housing and fix the axial position of that end of rotors relative to the housing. Bearing assemblies (32, 34) at the outer adjacent ends (20b, 22b) of the rotors support the other end of the rotors in the housing. The bearing assemblies (32, 34) include inner races pressed on shaft bosses (24b, 26b) and outer races slidably disposed in wear-resistant sleeves pressed into bores in housing end section 18. The outer races of bearing assemblies (32, 34) are biased away from bearing assemblies (29, 30) to remove radial and axial bearing play in all of the bearing assemblies.
