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).

An article comprising a ceramic material having a ceramic matrix composite backing adapted for use in a gas turbine engine is provided. The article comprises a structural ceramic material having a hot side facing toward a high temperature environment and a cold side facing away from the high temperature environment; and a ceramic matrix composite composition having a strength greater than the strength of the ceramic material attached to the back of the cold side of the ceramic material, whereby crack initiation and propagation are inhibited by the ceramic matrix composition to a greater degree than by the ceramic material.

A catalytic section of a combustor is formed from a spaced tandem array of corrugated panels. The exterior top and bottom surfaces of the panels are coated with a catalyst and the space between panels defines a passage for a fuel-rich/air mixture. The interior of the corrugated panels define cooling air passages for maintaining the catalyst and substrate on which it is formed, at acceptable temperatures.

A characteristic identifier for digital data is generated. Thereby, the information contained in a digital data set is reduced such that the resulting identifier is made comparable to another identifier made in the same manner. The generated identifiers are used for detecting identical digital data or to determine inexact copies of digital data. In one embodiment of the invention, the digital data is a digital audio signal and the characteristic identifier is called an audio signature. The comparison of identical audio data according to the invention can be carried out without a person actually listening to the audio data. The present invention can be used to establish automated processes to find potential unauthorized copies of audio data, e.g., music recordings, and therefore enables a better enforcement of copyrights in the audio industry.

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 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.
摘要:
In a gas turbine having a plurality of hybrid burners, each of which has a pilot burner and a main burner, a different pilot fuel quantity is fed to the pilot burners as a function of the load on the gas turbine. This provides both stable operation of the gas turbine at low loads and effective suppression of combustion oscillations at high loads.
摘要:
A burner, in particular for a gas turbine, in which combustion air is subjected to a vorticity by a vortex element, admits fuel to the vortical combustion air. At the same time, a pressure loss produced by the vortex element is small. A low NOx emission at virtually the same efficiency is achieved.
