Abstract: A condenser made of concrete for an axial exhaust turbine, the condenser being carried on a concrete raft and including a plurality of superposed bundles of heat exchange tubes, wherein the condenser includes end vertical tube plates connected via flexible seals to the walls of the condenser and intermediate vertical tube plates, said tube plates being secured to one another by ties and supporting the tubes of the bundles so that they are free to expand, the intermediate plates adjacent to the end plates being carried by internal steel support brackets that are fixed to the walls of the condenser. The bundles of heat exchanger tubes are easily mounted and maintenance thereof is facilitated.

Abstract: A turbine comprising at least one stage (20) having a diaphragm (1) which is split in two along a diametrical plane and which includes an outer ring (3) and an inner ring (6) interconnected by virtue of (10 and 11) serving to guide the turbine fluid, the downstream face (14) of the outer ring (3) being pressed against a ring (19) of the turbine stator (4), the diaphragm (1) being provided with sealing (17) providing sealing between the outer ring (3) and the stator (4), the turbine being characterized in that the sealing (17) are disposed on the outer edge (15) of the outer ring (3), in that the downstream face (14) of the outer ring (3) is provided with a land (18) at a distance from the outer edge (15) and bearing against the ring (19) of the stator (4), and in that communication (22, 27, 27') are provided for providing communication between the space (25) situated between the land (18) and the sealing (17), and a space downstream from the diaphragm (1) with the pressure in the space being less than the pre

Abstract: A connector for connecting two rotors (2, 4) together, said connector having a plate (1, 3) on the end of each rotor.It has clamping bolts (5) and a plurality of fixing components (6) for the plates (1, 3). Each fixing component (6) has a sleeve (17) cut in two. The sleeve is cylindrical on the outside and conical on the inside and is disposed in precision-reamed bores (12, 14) of the same dimensions in the two plates, the bores of one plate facing and being situated exactly adjacent to those of the other when the rotors (2, 4) are aligned. A shank (20) which has a conical portion (21) pushes back the parts of the sleeve (17) against the walls of the bores (12, 14) thus connecting the plates together without play.In the case of normal operation, the connector has high resistance to shearing due to the fact that there are no stresses in the components (6). In the case of a torque greater than the normal torque, the parts of the sleeve 17 are deformed but can be very easily extracted.

Abstract: A fixed pad thrust bearing for a turbomachine comprises a ring of sector-shaped pads separated by grooves and facing a thrust collar integral with the rotor of the turbomachine within a thrust bearing cage integral with the rotor. The ring bears on a deformable ring. Each pad is fed with oil via a space formed in the wall of the cage and facing an orifice in a bore in the pad. A front surface of each pad facing the collar is inclined relative to the rear surface of the ring. Each pad is further formed with a groove communicating with the aforementioned bore but not reaching as far as the inner and outer edges of the pad, being disposed adjacent the leading edge of the pad. The oil is recovered centrifugally from the outer edge of the collar. In this way, virtually all the power consumed by the oil goes towards providing the hydrodynamic supporting force, minimizing the shearing losses between the fixed and moving parts within the thrust bearing cage.
