Abstract: A granular aluminium oxide catalyst which has served for removal of nitrogen oxides and sulphur oxides from combustion gases and contains nitric acid and sulphuric acid is regenerated by treatment in a plurality of regeneration zones and reused for gas purification. The loaded catalyst is brought into direct contact in the first regeneration zone with SO2-rich gas from the second regeneration zone at temperatures of from 100 to 200 DEG C, the nitric acid being reacted with SO2 to form sulphuric acid and nitrogen oxide (NO). In the second regeneration zone, the catalyst is brought into direct contact with H2S from the third regeneration zone, at least the majority of the sulphuric acid being reduced to SO2 at temperatures of from 200 to 400 DEG C. The SO2 is passed into the first regeneration zone. In the third regeneration zone, H2S is generated from hydrogen and sulphur at temperatures of from 400 to 500 DEG C and passed into the preceding zone. Preferably, the sulphur reacted in the third zone is the elemental sulphur loading of the catalyst. In the fourth zone, the hot catalyst freed from its loading is cooled in direct contact with hydrogen.

Title: Machine for filling boxes with profiled bars (tubes)
Inventor: BUELTMANN RUDOLF
IPC: B65B19/34
Filed: 1987-07-24
Abstract: The profiled bars (1) with which the box (13) is to be filled are grasped between two vertical band portions (16a and 22a) of two conveyor bands (16 and 22) and are moved downwards and deposited into the box. Deposition takes place according to a set program in gap-free rows next to one another and in layers one above the other. By raising the box and moving it in the transverse direction, the outlet (24) of the tracks is set according to the particular depositing point. The vertical band portions (16a and 22a) are deflected at narrow blades (18 and 23), so that the width extension is only small. It is therefore possible to bring the lowering tracks directly up against the longitudinal walls of the box, thus allowing gap-free row formation. The conveyor bands (16) have respective horizontal portions (16b), where the profiled bars can be put down. <IMAGE>

Title: Clamping device for disc-shaped tools of hand tool machines
Inventor: SCHULZ MANFRED DIPL ING
IPC: B24B45/00
Filed: 1987-09-16
Abstract: A clamping device for disc-shaped tools on the working spindle of a hand tool machine is provided with an inner clamping flange and an outer counterflange. These two flanges receive the tool between them and are connected to the working spindle so as to be fixed in terms of rotation. The outer counterflange can be screwed directly or indirectly to the end of the working spindle. One of the two flanges can be displaced counter to the force of a tension spring coaxially with respect to the other flange by means of a lifting device. The construction of such a clamping device is now simplified and made less elaborate by the fact that the working spindle is incapable of displacement in the axial direction and the inner clamping flange is arranged so as to be fixed in terms of rotation but axially displaceable thereon. In this arrangement, the lifting device is arranged directly on the inner clamping flange.

Title: Hard-metal sewing-machine needle
Inventor: ARNDT FRANZ MARTIN
IPC: D05B85/00
Filed: 1988-03-26
Abstract: The hard-metal sewing-machine needle according to the invention, the needle stem of which is produced from a suitable commercially available, very finely powdered hard metal and the needle shank of which is produced from a steel hollow cylinder with a blind hole, can, after being joined by means of the known process of cold extrusion, be converted as an inseparable unit to the specific needle shape by known methods. The extremely high strength of the hard-metal needle stem allows large increases in the number of stitches and in the life of the needle tip. The hard-metal sewing-machine needle thus represents a high-performance tool for the economical sewing of webs of material consisting of textile fibres and manmade fibres and exceeds the performance of known steel-wire sewing-machine needles several times over.

Title: Belt conveyor having a stationary transfer edge constructed obliquely with respect to the conveying direction
Inventor: RADKE MANFRED DIPL ING
IPC: B65G15/62
Filed: 1988-03-31
Abstract: In a belt conveyor having a stationary transfer edge 1 constructed obliquely with respect to the conveying direction, a trapezoidal conveying surface 2 and two deflection 3 or drive drums 4 arranged so as to be displaced through the double skew angle 4 with their respective axes, a vertical change of direction is also to be achieved, in addition to the horizontal change of direction, by means of a construction, ascending towards the transfer edge, of the trapezoidal belt. The length increases x, which occur, in this arrangement, for the two trapezium sides are kept equally large by swivelling the axis W of the drive roller 3 from the horizontal by different swivelling heights on the two trapezium sides, which requires eccentric mounting of the deflection drum 3 on a swivelling pin 5. In addition to the deflection drum 3, for the purpose of fine adjustment of the straight running of the trapezoidal belt 2, the drive drum 4 can also be eccentrically mounted on a swivelling pin 5 (Figure 3). <IMAGE>
