The calcium bearing material may be lime which is added to the crushed coal and the calcium sulphide formed is removed from the devolatilization and gasification bed. The coal may be first devolatilized in a separate bed from which the calcium sulphide is removed and then gasified in an additional fluidized bed. Ash is removed from the bottom of the combustion bed. The removed portion of the gas stream is conducted into a gas turbine having a compressor, a combustor, and a turbine portion which drives the compressor and generator, so that the turbine exhaust gases are essentially free of sulphur compounds. The hot gases passing through the drying bed consist of a portion of the turbine exhaust gases. The gas flow through the fluidized beds consists of pressurized air from the turbine compressor.

Abstract: 1453065 Ultrasonic inspection devices KRAFTWERK UNION AG 10 Dec 1973 [8 Dec 1972] 57217/73 Heading G1G A workpiece is tested for internal defects by monitoring ultrasonic energy scattered by material inhomogeneities, other than the defects, from a location in the workpiece and varying the location until screening of the energy is detected from the intensity of the received ultrasonic waves, whereby the presence of a defect is indicated. In the Fig. 4 embodiment the intensity of ultrasonic energy scattered towards receiving probe 6 is monitored on a CRT while the distance between probe 6 and the transmitting angle probe 4 is varied. A marked intensity change occurs when transmission beam 7 moves clear of the lower edge of flaw 11; hence the flaw depth can be judged. The apparatus can be calibrated by use of a reference object with artificial flaws. The receiving probe 6 is an angle probe in alternative embodiments. Instead of varying the distance between the probes by probe movement, probe transducer pairs 3, 5 then 3A, 5A and so on may be used in turn as in Fig. 5. Alternatively the probes 4 and 6 may each be at a fixed distance from the flaw and include a variable angle transducer Fig. 3 (not shown) so that the transmitting and receiving beams intersect the flaw at an adjustable depth. Focusing transducers may be used.

[Also in Division F1] In a means for taking up the axial thrust exerted by a high-speed shaft 1, for example the power-transmitting shaft of a turbine, a shaft 7 is connected to the high-speed shaft and is driven thereby at a reduced speed, the axial thrust of the high-speed shaft 1 being transmitted to the shaft 7 which is provided with thrust bearings. In an embodiment, a turbineshaft 1 is supported radially by bearings 3 and, having a toothed ring 5, drives two shafts 7 which are supported radially by means of bearings 9. Each shaft 7 has a wheel-member 11 having a toothed-ring 13 which meshes with the toothed-ring 5 of the shaft 1, and has thrust bearings 15, 17 which engage a member 11.
