Title: A method for monitoring seafloor subsidence and for gravity monitoring an underground hydrocarbon reservoir
Inventor: ZUMBERGE MARK
IPC: G01V9/00
Filed: 2000-12-12
Abstract: The invention is a method for monitoring subsidence of the sea-bed (14) of a survey area (8) caused by compaction of an underground hydrocarbon reservoir (1), and comprises the following steps:  Conducting at least two series (S1, ..,Si,..,Sm) of time-indexed depth measurements (13a,.., 13n), with separation in time .DELTA.  between the measurement series characteristic of a significantly detectable long-term change of seafloor elevation due to compaction to take place in the reservoir. Measurements are time-indexed and corrected for tidal depth variations. Depth measurements (13) are conducted on survey stations (2) arranged on benchmarks (6) which have settled in the locally consolidated seabed (14). To handle short-term depth variations several stationary time-indexed short-time local reference depth measurement series (19r) are conducted at short-term local reference stations (18r) at benchmarks (6) during each separate measurement series (Si). The reference depth measurement series (19r) are continuous for correcting each depth measurement (13) for short-time tidal depth variations occuring during each separate measurement series (Si). To monitor compaction or seafloor subsidence during the series of measurements, the depth measurements (13, 19r) are conducted relative to a depth measurement (13r) during each series (S) at reference station (9) arranged on the seabed (14r) at a distance from the reservoir (8) being sufficiently far to be unaffected by long-term effects taking place due to compaction in reservoir (1).

Inventor: STROBEL JOAN M
IPC: B29C44/56
Filed: 2001-06-21
Abstract: The present invention is directed to a process for producing a polypropylene foam by mixing a high melt strength polypropylene and a blowing agent to form a melt mixture, reducing the temperature of the melt mixture at the exit of the apparatus to an exit temperature that is no more than 30~C above the melt temperature of the neat polypropylene while maintaining the melt mixture at a pressure sufficient to prevent foaming; passing the mixture through said exit shaping orifice and exposing the mixture to atmospheric pressure, whereby the blowing agent expands causing cell formation resulting in foam formation, and orienting said foam. The foam is useful as tape backings, thermal and acoustical insulation and as a diffuse reflector for use in optical applications such as computer displays.

Title: Procede de modification de synthetases de peptides de maniere qu'elles puissent n-methyler leurs acides amines de substrat
Inventor: SCHAUWECKER FLORIAN
IPC: C12N9/00
Filed: 2000-06-15
Abstract: L'invention concerne la modification des synthétases de peptides (PPS) de manière qu'elles puissent N-méthyler leurs acides aminés de substrat. Les PPS sont des enzymes qui synthétisent des peptides de manière non ribosomale. Les PPS possèdent une structure modulaire. Chaque module comporte un domaine d'activation, qui reconnaît l'acide aminé du substrat correspondant et le lie par covalence. La synthèse des peptides, catalysée par les PPS, s'effectue ensuite par condensation des acides aminés de substrat liés par covalence. Un nombre réduit de domaines d'activation connus est capable de N-méthyler les acides aminés de substrat liés. Ladite invention permet de transformer les domaines d'activation sans activité de N-méthyltransférase en des domaines d'activation possédant une activité de N-méthyltransférase, tout en conservant leur spécificité de substrat.

Title: Compensated multi-mode electromagnetic wave resistivity tool
Inventor: BITTAR MICHAEL S
IPC: G01V3/30
Filed: 2001-11-30
Abstract: A multi-mode resistivity tool for use in a logging-while-drilling(LWD) system includes an asymmetric transmitter design with multiple transmitters capable of generating electromagnetic (EM) signals at multiple depths of investigation. An array of at least three receivers is positioned amongst a transmitter array to detect the EM signals after they have traversed the region in the vicinity of the borehole. In a first mode, two pairs of receivers combine with the asymmetrical transmitter array to produce a plurality of compensated resistivity measurements. In an alternative mode, one pair of receivers, consisting of a receiver from each of the previous pairs, combines with the array of transmitters to create a plurality of non-compensated measurements. This multi-mode capability enables the resistivity tool to operate successfully in a wide variety of drilling formations and under a broad scope of drilling conditions.

Abstract: L'invention concerne l'acheminement par classe sur réseau, mis en oeuvre dans un réseau, par exemple un réseau informatique comprenant plusieurs processeurs informatiques parallèles situés dans des noeuds (Q00-Q22). L'acheminement par classe sur réseau permet à un processeur informatique de diffuser un message à une série (un ou plusieurs) d'autres processeurs informatiques du réseau informatique, par exemple des processeurs en colonne ou en rangée. Normalement, ce type d'opération nécessite l'envoi d'un message séparé à chaque processeur. Dans l'acheminement par classe sur réseau de l'invention, un seul message suffit, réduisant généralement le nombre total de messages dans le réseau ainsi que le temps d'attente pour effectuer une diffusion. L'acheminement par classe sur réseau est également utilisé dans les algorithmes d'inversion à matrice dense sur des superordinateurs parallèles à mémoire distribuée (fig. 1) à capacité (de multi-diffusion) fonctionnelle de classe de matériel. Ceci est possible grâce au fait que les modèles de communication d'inversion à matrice dense peuvent être desservis par les fonctions de classe de matériel, permettant ainsi d'obtenir des temps d'exécution plus rapides.
