Abstract: According to the present invention, there is provided a pushbutton switch cover sheet providing a unique design. A pushbutton switch cover sheet is provided with an operation plate of metal or hard resin having dividing grooves defining depressing operation members capable of displacement through depression. Therefore, there is no need to provide the casing of the apparatus with a frame defining key tops, making it possible to impart a novel design to the apparatus. The operation plate is formed as a thin plate, so it is possible to reduce a thickness of the apparatus as a whole. Further, the dividing grooves are provided with in-groove protrusions protruding into the dividing grooves and groove filling members fixed to the groove inner side surfaces and formed of a rubber-like elastic material, thereby making it possible to provide a pushbutton switch cover sheet of a high level of safety in which there is no fear of fingers being injured by the dividing grooves.

Abstract: A storage power station (S), for example an air storage plant, that includes a compressor unit (V), a turbine unit (T) and a storage volume (100) can be operated using a specific method of operation, which allows as fast a reaction as possible to changes in the load demands. Rapid changes in the load demands can be satisfied by controlling the power consumption of the compressor unit (V), which results in a variable net power output, with the power output from the turbine unit (T) remaining constant. The power of the compressor unit can be controlled approximately one order of magnitude more quickly than the power generation machine can be controlled. In the extreme, the compressor unit can simply be shut down, thus resulting in its drive power becoming available to an electricity grid within seconds. During this process, the turbine unit can continue to operate normally, and can slowly follow the power demand, thus reducing the load on the turbine.

Abstract: A sensor 11 detects the acoustic pressure at a first location in a combustion chamber 7 of a test rig 1 and produces an input signal which is a function of the acoustic pressure. A controller 13 receives the input signal and produces an output signal which is a function of the input signal. An acoustic actuator (16-18) receives the output signal and introduces into the combustion chamber 7 at a second location an acoustic pressure which is a function of the output signal. The acoustic actuator may comprise a fuel injector 18 or a loudspeaker. By using an appropriate control algorithm, acoustic boundary conditions corresponding to a particular gas turbine combustion chamber may be produced, at least in a certain frequency range.
