The invention relates to a device for converting thermal energy to electrical energy, comprising at least one thermoelectric module (19) which has an outer surface having a hot side (20) for contacting a heat source and having a cold side (22) for contacting a heat sink, wherein the hot side of the thermoelectric module is thermally conductively connected to a heat source, in particular an exhaust channel (11) of a combustion engine. The device further comprises a cooling channel (25) through which a cooling fluid can flow and which is thermally conductively connected to the cold side of the thermoelectric module. The cooling channel has at least one opening to the cold side of the thermoelectric module and is sealed in a fluid-tight manner around the opening with respect to the hot side of the thermoelectric module.

The invention relates to a turbine blade comprising a profiled vane around which working gas flows. The working gas cross-flows a front edge of the vane and flows away on a rear edge of the vane. The vane has a first and a second channel system for guiding two media separated from the turbine blade. Combustion taking place inside is reduced in a safe manner to maintain the service life of the turbine blade and to prevent damage in the gas turbine, such that a first outlet connected to the first channel system is arranged in the region of the rear edge for blowing out the first media into the working gas and a second outlet connected to the second channel system is arranged in the region of the rear edge for blowing out the second medium.

The invention relates to a blade for a turbine comprising a blade wall, a first channel for guiding a first medium and a second channel for guiding a second medium that can be supplied to the turbine blade separately from the first medium. In order to combine both media, which are supplied separately, into one mixture, a turbine blade has least one chamber which is arranged in the interior or in the blade wall and said chamber is connected to said channels via a respective connection line. In order to provide a particularly simple component that is economical to produce, the chamber and/or the outlet conduit are a least partially delimited and/or formed by an insert accommodated in the wall.

The invention relates to an open-cooled component for a gas turbine having an outer wall (20) which is subjected to hot gas and which at least partly defines a first cavity (15) for a first medium and in which through-openings (3, 12) are arranged, which through-openings (3, 12) open into the cavity (15) on the one side and into the hot-gas space (21) on the other side, and having at least one second cavity for admixing a second medium, this second cavity being fluidically connected to the through-openings (3, 12). In order to specify a component for a gas turbine with which flashback and spontaneous ignition during feeding of fuel into the cooling air can be reduced, it is proposed that the second cavity be formed by supply passages (9, 13) which are provided in the outer wall (20) and are connected via transverse passages (4) to the through-openings (3, 12) designed as through-bores, so that the two media cannot be mixed until inside the through-bores. A combustion chamber for a gas turbine and a gas turbine having such a component are also proposed.

A vehicle data bus system includes locating means which comprise a locating computing unit and a locating sensor system which contains at least one GPS receiver with associated GPS antenna and gyro data acquisition means, and a data bus via which connects a plurality of bus users in data communication with one another. The locating means contain a locating module which is embodied as one of the bus users and is configured to receive at least wheel speed data and forward/backward direction of travel data via the data bus, to acquire at least vehicle position data, direction of travel angle data, travel speed data and altitude position data as well as to output this acquired data onto the data bus. For this purpose, the locating module contains the location computing unit, the GPS receiver and a gyroscope or means for the bus-end reception and evaluation of gyro data of a travel dynamics/traction control system.
摘要:
An open-cooled component for a gas turbine is provided. The component includes an outer wall that is subjected to a hot gas and at least partially defines a first cavity for a first means. The outer wall is provided with through-openings which open up into the cavity on one side and into a hot gas chamber on the other. The inventive component also includes at least one second cavity for admixing a second means, said second cavity is connected to the through-openings in a fluid-connected manner. A combustion chamber for a gas turbine, and to a gas turbine including one such component is also provided.

A method and apparatus for creating links between a representation, (e.g. text data,) and a realization, (e.g. corresponding audio data,) is provided. According to the invention the realization is structured by combining a time-stamped version of the representation generated from the realization with structural information from the representation. Thereby so called hyper links between representation and realization are created. These hyper links are used for performing search operations in realization data equivalent to those which are possible in representation data, enabling an improved access to the realization (e.g. via audio databases).

The invention relates to a heat shield element for lining a combustion chamber wall, to a combustion chamber and to a gas turbine. The heat shield element comprises a hot side that can be exposed to a hot medium, a wall side opposite said hot side, and a peripheral side adjoining the hot side and the wall side and having a peripheral side surface. Relief slots are introduced into the material in an area of the heat shield element that is susceptible to material cracks induced by thermal stress, thereby limiting crack propagation.

The present invention provides a method and system for computerized synchronization of an audio stream having a first synchronized textual representation usable for subtitling of the audio stream in the original language, with a second synchronized textual representation which can be used as an alternative subtitle including a transcription of the original language into another language. Time synchronous links can be built between the audio stream and, for instance, the textual representations of the words spoken in the audio stream. More particularly, the second representation can inherit the synchronization between the audio stream and the first representation using structure association information determined between the first and the second representation.
