Title: Metode og apparat for fjerning av seismisk interferens
Inventor: ELBOTH THOMAS
IPC: G01V1/36
Filed: 2013-01-15
Abstract: En fremgangsmåte for å prosessere seismisk undersøkelsesdata, omfattende å fremskaffe en original samling av seismiske spor med seismisk interferens, å dele den originale samlingen opp i et flertall romvinduer og å fastlegge for hvert av nevnte romvinduer et vektorfelt som gir indikasjon på moveout av seismisk interferens og et estimat av seismisk interferens-moveout. Å fastlegge et estimat av seismisk interferens-moveout kan inkludere fastlegging av distribushjonen av lokale moveout-komponenter av moveout-vektorer i hvert av nevnte romvinduer, og å identifisere den nedre relative statistiske spredningen, slik som et normalisert standard avvik, over nevnte romvindu. En første fremgangsmåte for å fjerne seismisk interferens i den originale samlingen omfatter å fremskaffe et estimat ( p") av en seismisk interferens- moveout generert på basis av et vektorfelt for en seismisk interferens-moveout som er generert fra nevnte originale samling, å anvende en tau-p-transformasjon på nevnte originale samling for å generere en tau-p- transformert samling, å fastlegge en tau-p-demping i overensstemmelse med nevnte estimat av den seismiske interferens-moveout, å anvende nevnte tau-p-demping på nevnte tau p transformerte samling for å generere en delvis dempet tau-p-transformert samling, og å anvende en invers tau-p-transformasjon på nevnte delvis dempede tau-p-transformerte samling for å generere en delvis dempet samling. I en annen fremgangsmåte blir seismisk interferens i den originale samlingen i hovedsak fjernet ved å kalkulere en lokal strømningslinje som starter ved et senter-sample i retning forover og bakover for 2L+1 sampler for hvert sample i den originale samling (t, x) for å oppnå medianen eller gjennomsnittsverdien til alle amplitudene langs denne strømningslinjen, der seismisk interferens adderer opp konstruktivt, og ved å anvende linjeintegral-konvolusjon for å filtrere input-skudd-samlinge

Title: Method of and apparatus for crimping a portion of cylindrical hollow body and circumferentially turning in the edge of that portion
Inventor: KRUEGER JAN
IPC: B21D51/26
Filed: 1996-04-26
Abstract: A method and an apparatus for forming circumferentially extending necked and flanged parts at an end of a bilaterally open hollow cylindrical body. First and second axially aligned shafts carry axially displaceable first and second inner tools, respectively. Each inner tool has a circumferential body-shaping and a circumferential body-supporting surface. In a first axial position of the two inner tools the shaping surfaces together define a circumferential shaping groove situated inside the hollow body, and the body-supporting surfaces support the hollow body. In a second axial position the two inner tools are at a greater axial distance from one another than in the first position to allow introduction of a hollow body therebetween. A third shaft, carrying an outer tool having a circumferential shaping surface, extends parallel to the first and second shafts. A positioning arrangement is provided for aligning the circumferential shaping surface of the outer tool with the circumferential shaping groove and for radially moving the outer tool towards the two inner tools such that a circumferential portion of the hollow body is deformed and forced into the shaping groove causing the two inner tools to axially spread apart from one another.

Title: Osmotic implant with membrane and membrane retention means
Inventor: SCOTT GILBERT J
IPC: A61K9/22
Filed: 2002-06-21
Abstract: An osmotic delivery system for controlled delivery of a beneficial agent includes an implantable capsule containing a beneficial agent and an osmotic engine that swells on contact with water, thereby causing the release of the beneficial agent over time. The osmotic delivery system has a membrane material that allows a controlled amount of fluid to enter from an exterior of the capsule, while preventing the compositions within the capsule from passing out of the capsule. The osmotic delivery system is designed to meet at least the operating pressures of 1000 psi. The membrane material is cast, calendered or extruded followed by machining (i.e., die-cutting, stamping or otherwise cutting to shape) to provide a uniform nonribbed membrane material. The capsule also includes a membrane material-retaining means that is positioned at a fluid uptake end to retain the membrane material within the capsule, even under periods of high pressure.
