Abstract: A stationary power-generating plant of the type which includes a turboset comprising an axial-flow combustion gas turbine, an axial flow combustion air compressor and a driven machine such as an electrical generator which are all coupled together and mounted for rotation about a common axis. The driven machine is located within a hollow chamber surrounded by an intake duct which provides for a flow of combustion air to the compressor and the intake duct is arranged co-axially with the rotational axis of the turboset and is connected to the air inlet end of the compressor by means of a convergent conical annular duct thereby providing axial flow of air to the compressor inlet.

Abstract: Nuclear power station having a reactor buried in rock and machine groups formed with the use of turbines, compressors, generators or other apparatus, inclusive gas conduits; the individual machine groups and the gas conduits are arranged in rooms hollowed out in the rock for receiving and supporting these; to each group there leads at least one tunnel hollowed out in the rock; a safety chamber for a machine group concerned is situated adjacent the group and is secludable relatively to the atmosphere.

Abstract: A locking device for releasably fastening parts to rotors of fluid flow machines, the base portions of the parts to be secured fitting in a form-locking manner in at least approximately axially extending fixing slots provided at the circumference of the rotor, the locking device including fixing elements which can be inserted into depression means extending transversely with respect to the axially extending fixing slots and provided in the rotor and into recesses provided in the base portions of the parts to be secured. The depression means are provided at the region of the axially extending fixing slots and divide the flanks of each such axially extending fixing slot into approximately equal parts and the recesses provided in the base portions of the parts to be secured in the assembled condition of such parts coincide with the depression means.

Abstract: Hollow body or structure for heated gases and under high pressure having an insulating intermediate space between an external wall and a perforated partition wall; the insulating space being provided with perforated intermediate walls situated parallel to the external wall and the partition wall; the throttling effect of the perforated partition wall and of the perforated intermediate walls increases from wall to wall outwardly from the inside of the hollow body.

Abstract: The lower half of the turbomachine casing is mounted so as to retain the casing half in a set horizontal plane despite thermal expansions and contractions. To this end, the support arrangement at one end of the casing half includes vertically disposed rods which have a coefficient of thermal expansion less than that of the casing as well as covers which are secured to the casing and rest on the rods in order to transfer the weight of the casing to the rods. When heated, the rods expand upwardly while the covers expand downwardly. The two expansion effects cancel each other so that the plane of the lower casing half is maintained set.
