Title: Carbon fibrils, method for producing same, and compositions containing same.
Inventor: TENNETT HOWARD G
IPC: C01B31/02
Filed: 1985-12-04
Abstract: This invention concerns an essentially cylindrical discrete carbon fibril characterized by a substantially constant diameter between about 3.5 and about 70 nanometers, e.g. between about 7 and 25 nanometers, length greater than about 102 times the diameter, an outer region of multiple essentially continuous layers of ordered carbon atoms and a distinct inner core region, each of the layers and core disposed substantially concentrically about the cylindrical axis of the fibril. Preferably the entire fibril is substantially free of thermal carbon overcoat. The invention further concerns a plurality of such fibrils. The fibril or plurality of fibrils of this invention may be produced by contacting for an appropriate period of time and at suitable pressure a suitable metal-containing particle with a suitable gaseous, carbon-containing compound, at a temperature between about 850 DEG  C. and 1200 DEG  C., the ratio on a dry weight basis of carbon-containing compound to metal containing particle being at least about 100:1. The fibrils are useful in composites having a matrix of e.g., an organic polymer, an inorganic polymer or a metal. In one embodiment the fibrils are incorporated into structural materials in a method of reinforcement. In other embodiments the fibrils may be used to enhance the electrical or thermal conductivity of a material, to increase the surface area of an electrode or capacitor plate, to provide a support for a catalyst, or to shield an object from electromagnetic radiation.

Patent EP-0730507-A4 (EP)
Inventor: SELLAR JOHN G
IPC: E21C25/60
Filed: 1994-01-12
Abstract: L'invention se rapporte à un nouvel appareil (15) pour l'excavation d'une masse (19) par exemple de roche (21). Cet appareil fonctionne en dirigeant sur la même masse simultanément un jet de fluide à vitesse élevée (14) et un faisceau laser pulsé (17). Ce faisceau laser (appelé ici faisceau laser briseur) vaporise la matière liquide à la surface de la roche et le fluide en jets confine la matière ainsi vaporisée, créant alors des ondes de chocs qui pénètrent dans la roche. Les ondes de choc confinées impriment une force plus grande que les ondes de choc non confinées et cette force accrue brise la masse de roche. Les jets de fluide servent également à enlever par lavage les particules désagrégées de la masse de roche, afin de former une nouvelle surface d'excavation.

Patent EP-0870282-A4 (EP)
IPC: G06T15/10
Filed: 1996-07-26
Abstract: Cette invention assure une capacité de décalage de données qui permet de trier les données en plus de rechercher la performance en couleurs en temps réel, avec une imagerie de haute qualité au moyen d'une recherche simple d'une base de données spatiales fondée sur une région de recherche de forme rectangulaire ou sur une recherche entre limites (fig. 13). Une mémoire auto-associative de comparaison de grandeurs numériques de tri (MAACGNT) effectue une recherche de limite, en introduisant une approximation conservative de la région de bord théorique et utilise une MAACGN dans laquelle les mots contenant des données stockées dans les domaines sont décalées sur des domaines correspondants dans un mot adjacent, en fonction des comparaisons de grandeurs numériques (fig. 7). Le procédé de traitement graphique en 3D stocke les paramètres d'un intervalle de polygone dans une base de données spatiales (804-814) et une opération d'interrogation est réalisée sur la base de données pour déterminer les intervalles ou les parties d'intervalle qui sont visibles (816 et 818), et applique une règle pour comparer la nouvelle partie d'intervalle à une ancienne partie d'intervalle sur une base sous-intervalle par sous-intervalle, ceci produisant des informations supplémentaires sur le bord du polygone dans une ligne de trame et un effet anticrénelage.

IPC: A61B10/00
Filed: 1996-11-20
Abstract: L'invention concerne un système de détection intra-utérine d'une ou plusieurs substances biologiques, telles que le méconium ou le sang. La présence dans le liquide amniotique de ces substances biologiques indique un état anormal justifiant une intervention de la part du médecin surveillant le travail et l'accouchement. Un câble souple (14) qu'on peut introduire dans l'utérus comprend au moins deux lumières. On utilise la première lumière afin d'extraire du liquide amniotique à travers un orifice (16) de la lumière et d'introduire ce liquide dans une chambre d'observation située à l'extérieur de l'utérus et au niveau de l'extrémité de la première lumière. Le médecin observe ce liquide afin de rechercher la présence d'une substance biologique ou on peut détecter ladite substance au moyen de l'un des différents instruments décrits. Il est préférable qu'une chambre d'observation visuelle soit présente afin de pouvoir exercer une détection visuelle également, si on utilise un instrument pour détecter la substance biologique. Ce dispositif permet de retirer du liquide souillé de l'utérus et d'y perfuser du liquide propre, de manière à limiter la concentration et l'effet de la substance biologique indésirable dans l'utérus.

Filed: 1997-05-30
Abstract: La présente invention concerne un procédé de production d'acide D,L-aspartique. Ce procédé consiste à faire réagir un acide ou un anhydride dicarboxylique insaturé tel que l'acide maléïque, l'acide fumarique, l'anhydride malique ou certains de leurs mélanges comportant un excédant d'ammoniaque aqueuse dans des conditions de température, de pression et de durée suffisantes pour produire du diammonium D,L aspartate. Le procédé consiste alors à neutraliser le diammonium D,L aspartate pour obtenir de l'acide D,L-aspartique. L'excédant d'ammoniaque n'étant pas entré en réaction et divers sous-produits peuvent être recyclés et utilisés selon le procédé, ce qui n'occasionne qu'un minimum de déchets et de coûts de production. Il en résulte que ce procédé convient particulièrement pour un processus de production continue qui peut se représenter commodément sous forme d'un organigramme fonctionnel où un réacteur pressurisé (10) reçoit un adjuvant de réaction depuis un bac d'alimentation (12), le réactif étant introduit ultérieurement dans un ballon de flashing (14) puis dans un bac de précipitation (16) où l'acide D,L-aspartique se forme par neutralisation, les sels d'acide dicarboxylique étant récupérés par centrifugation (18) et séchés dans un séchoir (20). L'acide D,L-aspartique convient ensuite à la production d'acide polyaspartique.
