Patent DE-3615560-A1 (DE)
Title: Method of machine-related and at the same time material-related quality control when performing shot-peening of metallic surfaces
Inventor: BERNASCONI JAKOB DIPL PHYS DR
IPC: B24C1/10
Filed: 1986-05-09
Abstract: Method of both machine-related and material-related quality control in the shot-peening of metallic surfaces with repeated use of series of test platelets of different thicknesses from the material of the component to be shot-peened. The platelets are shot-peened on one side under constant conditions and their deflection is graphically plotted as a function of the platelet thickness. The method is refined by plotting the product f.H<3> as a function of H, where f = deflection, H = platelet thickness. In this case, the curves produced are straight lines, which makes quality control simpler. Abscissa section H0 = a measure of the depth of penetration and slope dimension s = a measure of the size of the internal stresses in the shot-peened surface layer. Deviations from the set values are recognised by measured points falling outside the range of spread. <IMAGE>

Patent DE-3729102-A1 (DE)
Title: Adjustable bearing arrangement
Inventor: BUECHEL VEIT
IPC: F16C11/04
Filed: 1987-09-01
Abstract: The invention relates to an adjustable bearing arrangement which makes it possible to make the driving and transmission elements adjustable. The aim of the invention is to enable the adjustment of bearing systems in three degrees of freedom with little effort and to improve the electrical and mechanical safety of the arrangement during initial start-up and servicing. The essence of the invention consists in that a bearing pin adjustable in three degrees of freedom in the axial and radial direction is arranged eccentrically in a bearing bracket attached to a suspension means. The adjusting forces acting on a holding part via the bearing pin move the object to be adjusted mounted on this holding part into the desired position. The bearing pin mounted in the variable-position adjusting elements ensures that, when the latter are rotated, the radial and axial position is varied simultaneously or in succession. The solution according to the invention is employed primarily in instrumentation engineering and in machine construction where there is a requirement for adjustable driving and transmission elements. <IMAGE>

Filed: 1988-02-10
Abstract: A process is described for preparing a polycrystalline semiconductor material of enhanced purity. This process comprises forming a polycrystalline rod by chemical vapour decomposition of a precursor compound for a semiconductor material and by separating a central section of the polycrystalline rod, which section contains a significant proportion of the impurities of the polycrystalline rod deposited, from that section which has an enhanced purity. The separation of the central section of the polycrystalline rod can be effected by either drilling out a central core from the rod or, offset from the central section of the rod, drilling out cores having an enhanced purity. There is further described a polycrystalline rod of a semiconductor material having enhanced purity, which rod has been produced according to this process. Finally, the invention includes a single crystal of semiconductor material which has been produced from the polycrystalline rod having enhanced purity.

Title: Drum brake
Inventor: KLEIN HANS-CHRISTOF
IPC: F16D65/28
Filed: 1988-07-21
Abstract: The present invention is based on the object of integrating the brake-actuating devices for a drum brake into the latter. In the course of efforts to this end, care must be taken that the actuating device does not become too heavy since otherwise the unsprung mass of the wheel to be braked will be increased to an excessive extent, which is undesirable. It is therefore proposed to arrange a roller lever mechanism consisting of the levers 11, 13 with the interposed roller 15 between the operating cams 8 and the energy storage spring 16 which provides the actual actuating energy. Small actuating forces are supplied by the electric motor 18. <IMAGE>

Abstract: It is known to lay out the floorboards of raised floors on grid girders, which are attached to the cover plates of legs of the raised floor. The grid girders are either inserted into suitable recesses in the cover plates where they may be made secure in these recesses by means of tongues which engage in boreholes in the cover plates, or else under more stringent specifications they are screwed into the reinforcement of the raised floor with the cover plates. Until this time, for the two variations of assembly, two different types of girders have also been produced. Both variations of assembly can be attained by use of the grid girder according to the present invention. For this purpose, the side walls of the grid girder are provided with beveled ends in such a manner that the grid girder, when viewed from the side, has the shape of a parallelogram. At the ends of both of the other walls of the grid girder are provided in turn tongues or oblong apertures for the passage of fastening screws. Tongues are intended for the loose engagement of the grid girder in the boreholes of cover plates, while with the other variation of assembly the fastening screws are fed through oblong apertures and are twisted or tapped into the boreholes.
