Abstract: A gasification reactor for producing crude gas, containing CO or H2, by gasification of ash-containing fuel with oxygen-containing gas, at temperatures above the melting temperature of the ash, has a reaction chamber formed by a membrane wall through which coolant flows, within a pressure container, is provided, with a narrowing transition channel into a gas cooling chamber, and spin-reducing, cooled bulkheads in the transition channel. The, wall that carries the bulkheads makes a transition, below the bulkheads, into a cylinder wall that is reduced in diameter, by a step having a corrugated surface. The cylinder wall, which is reduced in diameter, is enclosed by a further cylindrical wall, which is enlarged in diameter, which wall forms a second slag drip edge at its end, in the direction of gravity. The further cylindrical wall is disposed to be adjustable in its vertical position, with reference to the first drip edge.

Abstract: A digital signature generation (DSG) process which provides resistance against white box attackers is disclosed. This is done by applying specially selected data transformations to the inputs, outputs and internal parameters of the algorithm. In particular, the signatory's private key does not appear in the clear in our protected implementation. Our new white box implementation produces signatures that are compatible with signatures created by conventional implementations; thus our solution facilitates interoperability and can be used as a drop-in replacement for conventional implementations. In particular, we describe transformations to the key (d) and the generator domain parameter (usually denoted G or g) of the digital signature generation processes, such that embodiments of the invention can produce signed messages which appear to a verifier as if the key (d) was used, without actually ever using the key (d). This makes it impossible for an adversary to ever observe the key (d), as it is not actually used. Further embodiments include additional protections to make it even harder for an adversary to deduce the key (d) by observing the process which generates the digital signature.

Abstract: Method for efficient computation of wave equation migration angle gathers by using multiple imaging conditions. Common reflection angle or common azimuth gathers or gathers including both common reflection angles and common azimuth angles are produced as the data are migrated. In the course of either wave equation migration or reverse time migration, the pressures and particle motion velocities that need to be computed are sufficient to also compute the Poynting vector pointing in the direction of source-side (35) or receiver-side (37) wavefield propagation. From that, the reflection and azimuth angles can be computed (38). The seismic images can then be stored in the appropriate angle bins, from which common reflection angle or azimuth data volumes can be assembled (39).

Abstract: The present invention relates to filters used to remove debris from water being sucked into a piping system. It has particular application use in nuclear power plants, which, after a loss of coolant accident, must pump cooling water back into the reactor core from a collection sump. This water may contain various types of debris that must be removed before the water is sent back into the reactor cooling system. There are restrictions on the allowable pressure drop across the strainer and the space available for installing this equipment. The finned strainer of the present invention addresses these issues while maximizing the quantity of debris filtered from the water.
