Abstract: The keys which are used to activate the machine functions are embodied as keys (T1 Tn) which are directly connected to one of the SPS inputs (9). One of the several key planes can be selected by the user interface (13) of the PC coupled to the SPS. A control unit (4), which is connected to the SPS inputs (9) and which processes data in the SPS, is provided. Said control unit contains information about the keyboard layout of the keys (T1 Tn) on the respectively selected key plane by the PC by means of the data interface (8) and comprises a key signal which is arranged on the SPS entry (9).

Abstract: A heat shield according to the invention on a support structure comprises a number of heat shield elements, which are configured and arranged on the support structure such that they abut each other leaving gaps. The support structure of the heat shield according to the invention has a peripheral direction and an axial direction, the heat shield elements abutting each other in the peripheral direction of the support structure leaving a gap, hereafter referred to as a peripheral gap, and in the axial direction of the support structure leaving a gap, hereafter referred to as an axial gap. Both the peripheral gaps and the axial gaps are also sealed by sealing elements, the sealing elements sealing the axial gaps being at a different distance from the support structure from the sealing elements sealing the peripheral gaps.

Abstract: A heat shield configuration, particularly for protecting supporting structures and structural parts of gas turbine plants against a hot fluid. The heat shield has an inner lining which consists of a heat-resistant material and which is composed of plate-shaped heat-shield elements resistant to high temperatures and are disposed next to one another with gaps in-between. The heat-shield elements cover the entire area of the structural part. The heat shield is anchored so as to be thermally movable to the supporting structures and parts by bolts. The heat-shield element is formed of an erosion-proof and corrosion-proof material. An insulating brick formed of a refractory ceramic is disposed in each case between each heat-shield element and the supporting structure or parts.
