Abstract: A turbine blade comprising at least one cooling element, a cooling duct for conducting a cooling medium, and a leading edge is provided. The cooling element is located within the flow of the cooling medium and is designed in a cog-shaped manner. The cooling duct is formed within the turbine blade for conducting a cooling air flow and extends along the flow attacking edge in at least some sections. The cooling elements are successively arranged in a stationary manner inside the cooling duct in the longitudinal direction. Each individual cooling element has a cooling capacity that is adapted to a predefined cooling requirement for the leading edge in the vicinity of the cooling element.

Abstract: A turbine blade comprising a plurality of ribs arranged one after the other in a cooling channel extending along a leading edge is provided. The plurality of ribs is split into pairs of ribs formed by two ribs arranged in the form of a skating step.

Abstract: A cooled turbine rotor blade for a gas turbine which is traversed axially by flow and is equipped with an attachment area and an airfoil profile is provided. Meandering cooling channels with interposed deflecting regions are provided in the interior of the airfoil profile. In the deflecting regions, it is possible to prevent dead water regions, which are generated in the prior art, by virtue of at least one of the ribs running so as to curve towards the leading edge or towards the trailing edge in the region of the airfoil tip. At the same time, an opening is provided in the curvature of the rib. Through this opening a part of the coolant flows in the deflecting region and can pass over into the adjacent cooling duct.

Abstract: The method for executing a program on a processor having a multithreading architecture includes identifying at least two processes of the program, the processes being executable independently of one another in a parallel manner and essentially using the same joint resources. The at least two identified processes are associated with different threads of the processor, and the program is then executed by executing the at least two identified processes in the associated threads in a parallel manner. As a result of the fact that those processes which essentially use the same joint resources are identified, the probability of capacity limits of those units of the processor which are not multiply provided in the processor being exceeded is reduced.

Abstract: Even a layer system, provided with a protective coating and used in a hot gas atmosphere needs to be cooled. However, said cooling is often insufficient, as far as cooling pipes are arranged relatively far from the external surface of said layer system. In order to solve the problem, the inventive coolable layer system consists of intersecting cooling pipes.

Abstract: A structural part of a gas turbine plant is cooled by branching off a partial mass air stream, after being compressed by a compressor of the gas turbine plant, from a main mass air stream. The cooling partial mass air stream is ducted in a closed duct to the structural part to be cooled. At the same time, the partial mass air stream undergoes, independently of the main mass air stream, additional compression which is carried out by utilizing the rotational energy of a turbomachine shaft of the gas turbine plant. The novel gas turbine plant therefore is provided with a secondary compressor. The invention is suitable particularly for use in stationary gas turbine plants.

Abstract: An apparatus which permits simultaneous use as reaction vessel for taking up one or more reaction liquids, for incubating and storing these liquids and for carrying out optical measurements is described. The apparatus performs functions of the reaction vessel and functions of the apparatus for liquid uptake. This makes it possible for analysis to be completely free of carryover while, at the same time, requiring minimal use of consumable materials or rinsing solutions.
