Patent CA-2316710-A1 (CA)
Inventor: DEFLANDRE JEAN-PIERRE
IPC: G01V1/28
Filed: 2000-07-26
Abstract: - Méthode d'analyse automatique de signaux acquis par un ou plusieurs capteu rs d' ondes élastiques pour pointer automatiquement avec une grande précision s ur eux, au moins un instant significatif tel que l'instant de première arrivée sur chaque capteur et/ou l'instant de fin de ces mêmes signaux. - La méthode comporte essentiellement une détermination de la pseudo-période correspondant à l'inverse de la fréquence dominante du spectre de fréquence de chaque signal acquis, le codage de chaque signal acquis pour former un signa l codé en binaire par référence à une première valeur-seuil dépendant du signa l acquis, la formation pour chacun d'eux d'un signal intégral par sommation du signal codé en binaire sur une fenêtre glissante de manière à déterminer une deuxième valeur-seuil, et le positionnement de l'instant significatif recherché sur chaque signal acquis par référence à un instant où le signal intégral correspondant atteint cette deuxième valeur-seuil. La méthode est auto-adaptative car elle utilise des paramètres (les valeurs-seuils notammen t) qui dépendent des caractéristiques des signaux reçus. - Applications notamment à la surveillance sismique (active ou passive) de gisements souterrains.

Abstract: Containers for animal feed or the like are made from a binder (starch and starch grain flours), mixed with organic fibers (hay, straw, paper, wood fiber, and the like), which is then mixed with a reactive solution (water, or water and a starch modifier). The resulting wet paste is formed into containers by pressing in a hot die set under elevated temperature and pressure for a predetermined time. In an alternative embodiment, the fiber material may be omitted to produce a container made from binder and starch modifier only. The containers are then dried and may then be coated with an edible preservative coating.

IPC: C12Q1/689
Filed: 1999-01-05
Abstract: The invention provides a method to differentiate between bacteria from the Actinomadura madurae group of bacteria and the Maduromycetes taxa using two nucleic acid probes that are complementary to a conserved region of the Maduromycetes 16S rRNA genes and to a conserved region of the Actinomadura madurae group of bacteria 16S rRNA genes, respectively. The probes permit the rapid detection of DNA coding for the 16S rRNA in a sample differentiating the Actinomadura madurae group of bacteria from Maduromycetes within the Actinomycetales order as well as the A. madurae group of bacteria and Maduromycetes from streptomycetes. The method is accurate and reproducible.

Inventor: SOFIA MICHAEL J
IPC: C07G11/00
Filed: 1999-02-03
Abstract: La présente invention concerne un procédé de synthèse de .beta.-oligosaccharides, dans lequel on utilise des alkylsulfényl- ou arylsulfényl-2-déoxy-2-N-trifluoracétamidoglycopyranoses comme donneurs de glycosyle via la glycosylation du sulfoxyde, à la fois en solution et en phase solide. Une fois activés dans les conditions de glycosylation, ces donneurs produisent les .beta.-glycosides de façon exclusive et avec un rendement élevé. Etant donné que le groupe trifluoroacétamido est facilement éliminé dans des conditions douces, le groupe amino correspondant peut être dérivatisé de manière adéquate, même en présence de groupes hydroxyle non protégés. L'invention concerne la conception, la construction et l'analyse de bibliothèques de disaccharides, ainsi qu'un procédé permettant de synthétiser le donneur de glycosyle.

Title: Production of heavy hydrocarbons by in-situ hydrovisbreaking
Inventor: GREGOLI ARMAND A
IPC: E21B36/02
Filed: 1999-06-23
Abstract: An integrated process is disclosed for treating, at the surface, production fluids recovered from the application of in situ hydrovisbreaking to heavy crude oils and natural bitumens deposited in subsurface formations. The production fluids are comprised of virgin heavy hydrocarbons, heavy hydrocarbons converted via the hydrovisbreaking process to lighter liquid hydrocarbons, residual reducing gases, hydrocarbon gases, and other components. In the process of this invention, the hydrocarbons in the production fluids are separated into a synthetic-crude-oil product (a nominal butane to 975 °F fraction with reduced sulfur, nitrogen, metals, and carbon residue) and a residuum stream (a nominal 975 °F + fraction). Partial oxidation of the residuum is carried out to produce clean reducing gas and fuel gas for steam generation, with the reducing gas and steam used in the in situ hydrovisbreaking process.

IPC: D04H3/14
Filed: 1999-10-29
Abstract: A nonwoven web of multipolymer fibers is described that is unidirectionally stretched and permanently elongated at ambient conditions and exhibits a substantial increase in tensile strength in the stretch direction. The ratio of tensile strength of the web in the direction of fiber orientation to the tensile strength in the other direction is at least about 10:1. The ratio of elongation at peak load in a direction transverse to the direction of fiber orientation is at least about 6:1. The multipolymer fibers normally are a blend of polyethylene and a polypropylene homopolymer or copolymer, one of which is a dominant phase and one of which is a disperse phase. A third component having elastomeric properties that is a least partially miscible with one or both of the other components is included in some blends. The nonwoven webs are stretchable well beyond their initial dimensions in the direction perpendicular to the stretch direction and are especially useful in laminates with elastomeric members for use in disposable absorbent articles to impart elasticity thereto.
