  • Publication number: 20240120507
    Abstract: A process is proposed for producing a bipolar plate for an electrochemical device, said process comprising providing a first main plate body and a second main plate body as fibrous shaped bodies including carbon fibers and each having a joining face and an opposing useful face, infiltrating the main plate bodies with at least one carbon allotrope, locally applying silicon to respective joining sites in the joining faces, placing the joining faces against one another, such that the joining sites rest against one another and the useful faces of the two main plate bodies face away from one another, and at least locally heating the joining sites, such that the silicon melts and reacts with adjoining carbon to form a silicon-carbon bond.

  • Patent number: 11221396
    Abstract: In a method for generating a transillumination signal of a section of the subsurface, an HPEM radiation source radiates an electromagnetic pulse into the section for the purpose of exciting electromagnetically reactive structures to emit an electromagnetic response signal. For the pulse, a pulse duration of at most 500 ns, a center frequency in the range between 10 MHz and 10 GHz, and a bandwidth in the range from 10% to 150% of the center frequency is set. The transillumination signal is formed as the sum of response signals received at a measuring location. In a method for detecting a cavity in the subsurface, the above method is carried out, and the structures are detected from the transillumination signal with the aid of a detection method, and the cavity is detected if the structures satisfy a detection criterion.

  • Patent number: 7509301
    Abstract: Systems and methods are provided for data processing. As disclosed herein, such systems and methods may include providing a data model with a set of entity types and set of attributes for each entity type, providing customizing data for the data model, the customizing data indicating data sources for the attributes and describing data structures being provided by the data sources, querying the attribute data for at least a first attribute of the set of attributes of one of the entity types, determining from the customizing data, if a single data source for the first attribute data of the one of the entity types is available, if such a single data source is not available, determining at least first and second ones of the data sources which in combination comprise the first attribute data of the one of the entity types, generating a sub-query for each one of the at least first and second data sources, and combining the results of the sub-queries to provide a query result.

  • Patent number: 7498697
    Abstract: The functionally critical series connection of high-voltage-resistant resistors (Rn, R?n) in a Marx generator (11) is replaced according to the invention by a molding (12, 12?) composed of conductive plastic, which, depending on the configuration grouping of the capacitor bank (Cn), runs over the geometric series of capacitor connections (An, A?n) resulting from this and is connected to them, for example by riveting or screwing (13), in which case it is also possible to use more than one continuous molding, instead of a single molding.

  • Patent number: 7002300
    Abstract: Intensive microwave radiation in particular of great band width and energy over a relatively long period of time in the form of long pulse packets with a high pulse repetition frequency and a very high frequency spectrum can be achieved if microwave irradiation is effected during the discharge of a capacitive high-voltage generator (35) by way of the antenna (26) into a series of successive capacitors (13) to be connected in parallel. They are preferably constructed in the form of a concentric stack, connected to the antenna (26), of which the outer electrodes (16) which are at a reference potential are in the form of a continuous tube within which annular electrodes (15) are disposed on a carrier (20) in axially spaced relationship with each other in such a way that at the same time they act as the electrodes of arc switches (39) for successively switching on subsequent capacitors (13).
