Abstract: A hydrocarbonaceous feedstock is converted in an integrated hydrotreating and hydrocracking process by combining with a hot hydrocracking zone effluent recycle stream containing hydrogen, and the mixture is passed to a denitrification and desulfurization reaction zone to produce hydrogen sulfide and ammonia to thereby clean up the fresh feedstock. The resulting hot, uncooled effluent from the denitrification and desulfurization zone is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrotreating zone with a hydrogen-rich gaseous stream to produce a vapor stream comprising hydrogen, hydrocarbonaceous compounds boiling at a temperature below the boiling range of the fresh feedstock, hydrogen sulfide and ammonia, and a liquid hydrocarbonaceous stream wherein at least a portion of this liquid stream is then passed to a hydrocracking step to produce the hot hydrocracking effluent recycle stream which is passed back to the hydrotreating zone.

Abstract: Boronic acid containing polymers are used to form bioinert gels and multilayer surface structures. These polymers form crosslinked hydrogels, which are highly swollen in water. The crosslinking can either be chemical or physical. Water soluble polymers containing boronic acid groups, such as phenylboronic acid (PBA), can be physically crosslinked by mixing the polymers in water with other polymers containing hydroxyls or carboxylic acids. Alternatively, surfaces can be treated by stepwise incubation with a solution of the boronic acid containing polymer, followed by incubation with a solution of a diol or carboxylic acid containing polymer. Many successive layers can be generated, increasing the thickness of the formed structure at each step. The bioinert gel or surface coating can be used for passivating the surfaces of medical implants (especially those based on transplanted tissue), or for passivating the surfaces of tissues in situ, decreasing the incidence or severity of such pathologic conditions as the formation of post-surgical adhesions, and thrombosis following angioplasty.

Title: Multi-channel audio energy loss compensation
Inventor: VILLEMOES LARS
IPC: G10L19/04
Filed: 2005-10-28
Abstract: For a multi-channel reconstruction of audio signals based on at least one base channel, an energy measure is used for compensating energy losses due to an predictive upmix. The energy measure can be applied in the encoder or the decoder. Furthermore, a decorrelated signal is added to output channels generated by an energy-loss introducing upmix procedure. The energy of the decorrelated signal is smaller than or equal to an energy error introduced by the predictive upmix. Thus, problems occurring for prediction based up-mix methods such as up-mixing signals that are coded with High Frequency Reconstruction techniques are solved, so that the correct correlation between the up-mixed channels is obtained or the up-mix is adapted to arbitrary down-mixes.
