Abstract: Method of improving the utilization of a sulphur absorbing material in a power plant for the combustion of a sulphur-containing fuel in a fluidized bed (14) of particulate material containing sulphur absorbent. According to the invention unconsumed absorbent in the interior part of the particles of the bed material is exposed by blowing gas into the bed (14) through special grinding nozzles (41) at a higher velocity than combustion air through the fluidizing nozzles (30). The gas pressure shall be so high that powerful gas jets are produced so that bed material particles are accelerated to a high velocity and, upon collision with other particles, are disintegrated. In a power plant for carrying out the method the grinding nozzles (41) are located at the lower part of the combustion chamber (12), preferably between its bottom (27) and a tube bundle (40) in the combustion chamber (12).

Abstract: A semiconductor device and method of making is disclosed wherein the semiconductor device includes a MOSFET with very shallow source and drain regions. The high sheet resistivity normally associated with such shallow regions is obviated by growing an epitaxial layer directly from the surface of the shallow source and drain regions, highly doping the layer, then forming a layer of refractory metal silicide on the epitaxial layer. The resulting structure yields a MOSFET having very shallow source and drain regions with very low sheet resistance.

Abstract: A water outlet 1 is adapted for mounting in a wall 10 between a room on the inner side of the wall and the outer side of the wall, which is exposed to atmospheric temperature. The water outlet has a valve element 8, on a spindle 9, which, by means of a valve-actuating member 5 at the opposite end of the outlet, is closed against its seat 2b. Further rotation of the valve-actuating member 5 brings about opening of an extra valve arrangement with a seat part 14 which is displaceable against the action of a spring 15 and in this way leaves a closing element 17 while freeing an opening, so that water present in the water outlet can run out through an outlet opening 4c next to the usual drawing-off point 4a. <IMAGE>

Abstract: Method for stabilizing a glide shoe loaded against an inner face of a revolving mantle of a roll adjustable in zones. The glide shoe is supported by an articulated joint on a piston which loads the glide shoe with adjustable pressure. In order to ensure lubrication of the glide face between the glide shoe and the inner face of the roll mantle, within an area of a front edge of the glide face as seen in a direction of rotation of the roll mantle, a shifting and/or steepening of compression pressure applied by the glide shoe through lubricant onto the inner face of the roll mantle is produced by means of a wedge space within the front edge of the glide face, said shifting and/or steepening in turn generating a moment having a direction opposite to a direction of a moment produced by frictional force of the glide face of the shoe. The thickness of the lubricant film is increased by this moment in the area of the front side of the glide face. Moreover, a glide shoe and a press roll or calender roll adjustable in zones for a paper machine make use of the method described.

The actual value of the magnetic flux is calculated for each sample interval, based on the sampled values of voltage (u via P7) and current (i via P8) according to the relation  DELTA  PSI =(u-R.i) DELTA t, where R is the resistance of the actual pole winding and the actual power stage. The instantaneous flux value  DELTA  PSI  received is added to the value of the magnetic flux previously received. The added value constitutes the actual value, referred to above, which is to be compared with tabulated values.

Abstract: The invention concerns a coupling for the detachable connection of two components, preferably a shaft with a hub, which for transmission of a torque are rotatably connected with each other by form-fit. When using such plug or form fit connections such as between a roll journal and a coupling box in a rolling mill, large tolerances must be expected that express themselves in peripheral directions and have adverse effects on the surface integrity of the rolled material. The invention provides for a clamping element which preferably can be inserted in the hub, acted upon by hydraulic fluid to keep the shaft in place relative to the hub. The clamping element is of a two-part design and can be filled with hydraulic fluid through appropriate devices, so that the hub is tightly fastened on the shaft upon assembly. For removal of the hub from the shaft, the pressure in the clamping element is simply relieved.

Abstract: The present invention relates to a fibre-optic sensor in the form of a Fabry-Pérot interferometer having one or both beam-reflecting elements designed as a Bragg grating (BG). What especially distinguishes the invention is that the chirp function of at least one Bragg grating is balanced against one non-desired measurand, such that the shift of the centre (xr) of the reflection which is a result of the variation of the non-desired measurand exactly compensates for the optical path difference which this measurand generates in the interferometer. This can be carried out by the chirp function having the form  LAMBDA 0(x) =  lambda 0/2n0 (1+Ax/BL0-Cx), wherein A, B and C are constants which are determined analytically or experimentally for each different case of desired invariance.
