20120029254ORDERED COBALT-ALUMINUM AND IRON-ALUMINUM INTERMETALLIC COMPOUNDS AS HYDROGENATION CATALYSTS - The present invention relates to a process for the hydrogenation, in particular the selective hydrogenation of unsaturated hydrocarbon compounds, such as the selective hydrogenation of acetylene to ethylene, using a hydrogenation catalyst comprising an ordered intermetallic compound, namely an ordered cobalt-aluminum or iron-aluminum intermetallic compound. According to another aspect, the present invention relates to a catalyst comprising a support and at least one specific ordered cobalt-aluminum and/or iron-aluminum intermetallic compound supported thereon, as well as to the use of specific ordered intermetallic cobalt-aluminum and iron-aluminum intermetallic compounds as catalysts. The ordered cobalt-aluminum and iron-aluminum intermetallic compounds proved to be highly selective and long-term stable catalysts, e.g. in the selective hydrogenation of acetylene to ethylene in a large excess of ethylene.02-02-2012

The ratio of the number-average molecular weight of water-soluble units to the number-average molecular weight of hydrophobic units is 2 to 1000, the additives being polymers that comprise at least one water-soluble unit that possesses at least one hydrophobic unit on one chain end and/or one hydrophobic unit as a non-terminal substituent and/or at least one hydrophobic unit that is incorporated between the water-soluble units of the polymer.12-03-2009
20090213866Data Communication System And Method - A data communication system having a plurality of input/output ports, a first group and a second group of switching units. Each switching unit has a plurality of input/output interfaces, whereby at least one of the plurality of input/output interfaces of each switching unit of the first group forms an input/output port of the communications system, and at least one other input/output interface of each of the switching units of the first group is connected via a communication link with an input/output interface of one of the switching units of the second group, so that a network is formed having at least one loop. The network is logically divided in at least two virtual subnetworks, each forming a spanning tree. Each switching unit of the first group is configured to assign an incoming data packet arriving at a particular input/output port to a predetermined one of the at least two virtual sub-networks.

20080298653Method for Topographical Presentation of Alterations in an Examined Brain - The invention relates to a method for the topographical presentation of structural alterations in an examined brain using volume data records. In line with the invention, this method is distinguished in that functional areas are mapped by extracting profiles, where the profiles record boundaries for two functional areas in the examined brain, in that the boundaries of the two functional areas are recorded by calculating a multivariant distance measurement, and in that a microstructure in the region of the boundaries of the two cortical areas is recorded and is compared with at least one microstructure in a boundary region of a reference brain. To increase the comparability of various areas in various brains taking into account the interindividual variability, it is expedient for the volume data records to be transformed to a target volume data record using an elastic registration method.12-04-2008
20080245446Protective Layer for an Aluminum-Containing Alloy for High-Temperature Use - Alloys containing aluminium are characterised by an outstanding oxidation resistance at high temperatures, that is based on, inter alia, the formation of a thick and slow-growing aluminium oxide layer on material surfaces. If the formation of the aluminium oxide layer reduces the aluminium content of the alloy so far that a critical aluminium concentration is not reached, no other protective aluminium oxide layer can be formed. This leads disadvantageously to a very rapid breakaway oxidation, and the destruction of the component. This effect is stronger at temperatures above 800° C. due to the fact that, often at this point, metastable Al10-09-2008
20080231268Imaging Method Based on Fractal Surface-Filling or Space-Filling Curves - The present invention relates to an imaging method and device for nuclear magnetic resonance. On the one hand, the method provides an image coding by means of an additional field which has, for each point of a two-dimensional grating surface within the sample, a different field strength value that occurs only once, as is the case, e.g., in fields based on fractal, surface-filling and space-filling curves. On the other hand, the read-out of the resonance behavior of a sample along a space-filling and/or surface-filling curve can be provided. In the first variant, a magnetic resonance (MR) image with a single high-frequency excitation without a time-varying gradient can be recorded, which in turn advantageously prevents the sound generation associated therewith. In the second variant, the sounds generated during read-out are advantageously shifted to another frequency range in which the human hearing is less sensitive. Furthermore, the device is relieved and the technical requirements with regard to it are reduced. In addition, it can be executed with known and existing devices.09-25-2008
