  • Patent number: 6876928
    Abstract: A method for determining from measured reflection data on a plurality of trace positions, a plurality of subsurface parameters. The method includes the steps of: preprocessing the measured reflection data into a plurality of partial or full stacks; specifying one or more initial subsurface parameters defining an initial subsurface model; specifying a wavelet or wavelet field for each of the partial or full stacks of the measured reflection data; calculating synthetic reflection data based on the specified wavelets and the initial subsurface parameters; optimizing an objective function, including the weighted difference between measured reflection data and synthetic reflection data for a plurality of trace positions simultaneously; and outputting the optimized subsurface parameters. A device for implementing this method is also included.

  • Patent number: 6872870
    Abstract: A method for the preparation of a eukaryotic organism, for example selected from plants, animals and fungi, showing constitutive, inducible and/or organ specific expression of a specifically modified TPS gene, which comprises the steps of providing a TPS gene; designing a suitable modification to the TPS gene by aligning the gene with the corresponding gene of yeast and establishing which part of the gene extends beyond the 5? terminus of the yeast gene; deleting or inactivating a part of the N-terminal region of the TPS gene extending beyond the 5? terminus of the yeast gene, in order to achieve an increased trehalose-6-phosphate synthase activity; cloning the thus modified gene into an expression vector under the control of a constitutive, inducible and/or organ-specific promoter; transforming a plant cell or tissue with the thus obtained expression vector; and regenerating a complete plant from the transformed plant cell or tissue.

  • Patent number: 6872238
    Abstract: Fine particles of dust and other pollutants in gas streams are agglomerated to form larger particles which are more easily filtered in downstream processing. In one embodiment, particles in successive portions of the gas stream are charged with opposite polarity, and the gas stream is introduced into an Evasé portion (12) to slow it down. Particles of different sizes have differential deceleration and therefore mix generally in the direction of flow, leading to agglomeration of oppositely-charged particles. In another embodiment, a gas stream is divided into substreams in respective parallel passages, and the particles in adjacent passages are charged to opposite polarity. Deflectors at the downstream end of the passages cause substreams of particles of opposite polarity to mix, with resultant agglomeration of oppositely charged particles.

  • Patent number: 6866085
    Abstract: The newly proposed cast aluminum alloy product has the composition consisting of 6.5-8.0% Si, 0.25-0.45% Mg, 0.08-0.40% Fe, 0.001-0.01% Ca, P less than 0.001%, 0.02-0.1% Ti, 0.001-0.01% B, optionally one or two of 0.05-0.3% Cr and 0.05-0.2% Mn, and the balance being Al except inevitable impurities. It has the metallurgical structure that an ?-Al phase in a surface layer is of average grain size different by 50 ?m or less from an ?-Al phase in an inner part, and that a maximum size of eutectic Si particles is 400 ?m or smaller. It is manufactured by injecting a molten aluminum alloy into metal dies at an injection speed of 0.05-0.25 m/second, and then cooling the injected alloy at a cooling speed of 20° C./or higher in a temperature range between liquidus and solidus curves in a state charged with a pressure of 30 MPa or higher. Since the cast product is good of ductility, it is used as a member for coupling another member therewith by calking or the like.
