摘要:
In a method of operating a power station plant, essentially comprising a gas-turbine group (40, 41, 46), a waste-heat steam generator (8) and a downstream steam consumer (30), the exhaust gas from the gas-turbine group (40, 41, 46) releases heat to the water conducted in counterflow through the waste-heat steam generator (8), and the steam produced is fed to the steam consumer (30) via at least one steam line (6). The water is at any temperature and is fed directly into the waste-heat steam generator (8) via at least one water line (11) having an allocated regulating valve (20) for limiting the flow. During the use of fuels having sulfur contents, the regulating valve (20) is controlled via the temperature of the exhaust gas at the discharge from the waste-heat steam generator (8), at a temperature measuring device (24).

A method for operating a gas turbine selectively in a simple cycle or in a combined steam turbine cycle increases the efficiency of the installation and provides easy switch-over from the simple cycle to the combined cycle, and at the same time providing for cooling the cooling air for the gas turbine. The method in accordance with the invention includes the steps of using the exhaust gas from the gas turbine to generate steam in a waste heat boiler for the steam cycle. A heat exchanger for cooling the cooling air is disposed in a duct for introducing a gaseous medium for mixing with the gas turbine exhaust. The gaseous medium cools the cooling air and is accordingly heated. The heated gaseous medium is mixed with the exhaust gas of the turbine, and the mixture directed to the waste heat boiler to generate steam for the steam turbine for operating in the combined cycle. In the simple cycle, the mixture is released to the atmosphere. A simply operated duct selectively directs the flow of the mixture.

A hearing aid includes a housing for accommodation of a signal processor for processing an audio signal into a processed audio signal compensating a hearing loss, and a receiver that is connected to an output of the signal processor for converting the processed audio signal into a sound signal, wherein the housing is configured to be positioned in an ear canal of a user without obstructing the ear canal, thereby leaving a passageway between a part of an ear canal wall and a part of the housing so that sound waves can escape from behind the housing through the passageway to surroundings of the user, the housing having an output port for emission of sound towards an eardrum of the user when inserted in the ear canal, and wherein the housing is coupled to an elongate member, which is configured to be placed in a pinna and outside the ear canal of the user for retention of the housing in the ear canal.
摘要:
A method and system for transforming customer-developed forms that may define the physical layout of a user interface to pages that define the logical layout of the user interface is provided. A transformation system transforms forms specifying both a logical and a physical layout of a user interface for a forms version of an application to pages specifying only the logical layout of the user interface for a pages version of the application. A customer may customize code rules and configuration data that is used by the transformation system to transform the forms of the customer to pages.
摘要:
The present invention relates to the production of novel, recombinant polynucleotides comprising the GIR1 ribozyme, or a variant thereof, vectors comprising such polynucleotides and recombinant host cells comprising such polynucleotides and/or such vectors. The invention furthermore relates to the use of said polynucleotides in the treatment of an individual suffering from a disease associated with or caused by instability of a transcript of said second subsequence such as cancer, cachexia, α-Thallasemia or leukaemia.
摘要:
Using a message exchanger (“message exchanger”), data messages are exchanged between entities in a decentralized, distributed, potentially heterogeneous, network environment. The message exchanger employs XML (extensible Markup Language). To accomplish this, the entities on both ends of the message exchange understand, identify, and parse the message format. The message exchanger defines such a mechanism. Data messages are broken down into two portions—one portion (the body) is intended from an ultimate destination and the other portion (the header) is intended for intermediate destination and/or the ultimate destination. The body may be defined so that it must be understood by the ultimate destination. The header may be defined so that it must be understood or changed. Regardless, the data in the body is delivered intact to the ultimate destination. The message exchanger defines a message envelope exchange format in XML over a transport protocol, such as HTTP (HyperText Transport Protocol). This format allows for the execution of RPC (Remote Procedure Call) over XML, but it can be used for any message exchange over a network.
