Inventor: MCCANDLISH LARRY E
IPC: B22F9/02
Filed: 1990-11-02
Abstract: L'on décrit un procédé destiné à la production de poudres composites à microstructure ultrafine. Le procédé comporte trois étapes coordonnées: 1) la préparation et le mélange d'une solution de départ; 2) le séchage par pulvérisation de manière à former une poudre précurseur homogène; et 3) la conversion thermochimique du précurseur en une poudre ayant la phase nanométrique désirée, au moyen d'un lit fluidisé. Le séchage par pulvérisation et la conversion par lit fluidisé sont deux technologies dites à échelle et fournissent le moyen de produire des quantités de poudres composites en vrac nanométrique à faible coût de fabrication. L'on contrôle les paramètres de traitement afin d'assurer le maintien de l'uniformité chimique et microstructurale à l'échelle nanométrique (moins de 0,1 micron). Le procédé de conversion par vaporisation est une technologie polyvalente s'appliquer à une variété de poudres composites en phase nanométrique métal-métal (par exemple W-Cu), céramique-métal (par exemple WC-Co), et céramique (par exemple Al2O3-SiO2) et à des poudres composites en phase nanométrique céramique-céramique (par exemple Al2O3-SiO).

Abstract: Une tête d'impression (10), en particulier une tête d'impression à diode électroluminescente (DEL), possède un appareil amélioré pour distribuer des signaux à des éléments individuels d'impression, par exemple des DELs, qui sont utilisés dans la tête d'impression, en particulier, cette tête d'impression contient plusieurs rangées d'éléments d'impression, en général des rangées (252, 254, 256) de diodes électroluminescentes, et un nombre correspondant de circuits d'attaque (232, 234, 236) tous montés sur un organe commun, cet organe étant par exemple une plaque métallique rigide (65). Chacun des circuits d'attaque est connecté à une rangée correspondante d'éléments d'impression. Toutes les rangées d'éléments d'impression sont généralement situées suivant une orientation co-linéaire le long de l'organe commun et les circuits d'attaque sont agencés de manière co-linéaire sur un côté des rangées. Une pluralité de moyens de distribution sous la forme de plaques d'étalement (210, 310, 410) ou incorporés comme un réseau de circuit sur les boîtiers ou puces de circuits intégrés formant les circuits attaque assurent la distribution des données et des signaux de synchronisation ou circuits d'attaque pour commander le sélection et la synchronisation des courants d'attaque respectifs. La tête d'impression se caractérise par des moyens d'interconnexion (214, 216, 312; 314, 316, 412) qui assurent l'interconnexion entre les moyens de distribution à la manière d'une connexion en guirlande de sorte que les signaux de synchronisation et les données passent d'un moyen de distribution à un autre par l'intermédiaire de ladite connexion en guirlande.

IPC: A61C8/00
Filed: 1991-10-04
Abstract: The invention relates to a method for treating the surface of surgical implants made of titanium or a titanium alloy, for instance dental implants, before implantation in bone tissue. The method results in a roughened exterior implant surface and at the same time a cleaning action is obtained, should there be any contaminants. The surface is blasted with particles of an oxide of titanium, preferably titanium dioxide. In this way an implant having an improved retention in bone tissue is obtained. The Blasted implant is used in a method for treating toothlessness.

Abstract: Appareil de fabrication de pieux ou de poutres en béton précontraint, et notamment de traverses de chemin de fer. L'appareil comporte un moule de coulage séparable en segments dont chacun a la même longueur que la poutre que l'on veut obtenir. Des dispositifs de mise en tension des fils de précontrainte traversant les segments sont disposés aux extrémités du moule de coulage. Lors du durcissement du béton dans le moule, on peut sectionner les fils entre les segments respectifs à l'aide d'un dispositif de coupe afin d'obtenir des poutres précontraintes séparées dont la longueur est déterminée par les segments du moule. Les segments voisins sont reliés les uns aux autres par au moins un passage ouvert (3) de section trapézoïdale entourant les fils continus de précontrainte (6), le moule (16) est porté par un organe porteur (13) apte à se déplacer dans le sens vertical, et des tiges de support verticales (34) sont disposées au niveau de chaque passage ouvert (3) entre des segments voisins du moule. Ces tiges de support (34) traversent le fond du moule (16) et peuvent se déplacer indépendamment de celui-ci dans le sens vertical. Après le durcissement du béton dans le moule (16), les poutres (1, 1') reliées les unes aux autres sont toujours soutenues par les tiges de support (34) pendant le démoulage réalisé lorsque le moule (16) se déplace vers le bas.

Abstract: A novel Phillips catalyst for the homopolymerisation of ethylene and the copolymerisation of ethylene with  alpha -olefins, contains, as catalytically effective components, a finely divided, phosphorus-containing chromium catalyst on an aluminum silicate support, and organolithium, organosodium, organopotassium, organomagnesium, organozinc, organoboron and organoaluminium compounds as cocatalysts. The finely divided, phosphorus-containing chromium catalyst on an aluminium silicate support can be prepared by applying at least one organic phosphorus (III), (IV) and/or (V) compound and at least one chromium (III) compound which does not react with said phosphorus compounds under the reaction conditions used, in any desired sequence, one after the other or simultaneously, to a finely divided aluminium silicate hydrogel or xerogel with formation of a catalyst precursor (A'), and activating the catalyst precursor (A') at elevated temperature in an oxidising atmosphere, forming the chromium catalyst (A). The novel Phillips catalyst gives ethylene homopolymers and copolymers of high toughness, but nevertheless good processing properties.

Abstract: A delay line having feedback from a control circuit at the output of the delay line controls the delay line duty cycle to within a specified range. The delay line comprises at least one delay unit (10) having control inputs to each delay unit The output of the delay line feeds to a low-pass filter (LPF) (32). A voltage proportional to the duty cycle of the delay line output is generated within the LPF and fed to a differential amplifier (34). The differential amplifier is in turn coupled to the control inputs of each of the delay units. When the voltage signal from the LPF is high (duty cycle is high), the differential amplifier will generate a signal causing the fall time of the signal propagating through the delay line to increase and rise time to decrease. This will decrease the high cycle time at the output of the delay line. When the voltage signal from the LPF is low (duty cycle is low), the differential amplifier will generate a signal causing the fall time to decrease and the rise time to increase. This will increase the high cycle time at the output of the delay line.
