Title: Process for powder-metallurgical production of a workpiece based on an aluminium alloy having high strength in the range between room temperature and 300@C
Inventor: COUPER MALCOLM JAMES DR
IPC: B22F3/16
Filed: 1987-08-08
Abstract: A workpiece of an aluminium alloy having high strength in the range between room temperature and 300@C is powder-metallurgically produced by melting an alloy of the type Al/Fe/X having X = Zr, Ce, Mo, Cr, Y, V, atomising the melt in a gas stream to give a fine powder and compacting the powder in the temperature range between 400 and 450@C under a pressure of from 1000 to 5000 bar to give a compact (pressed body). The compact is then subjected to a further thermomechanical reshaping (forming) in the temperature range between 200 and 350@C, with the deformations based on the reduction in cross-section in the case of rolling, drawing and swaging being from 15 to 55% and in the case of upsetting being from -0.5 to -1.0 measured as elongation epsilon , with <IMAGE> ho = thickness of the workpiece prior to upsetting hf = thickness of the workpiece after upsetting.

Title: Device, in particular a tachometer wheel, for contactless tapping of rotational speed or contact making in machines
Inventor: MUELLER WERNER
IPC: G01P3/487
Filed: 1987-09-09
Abstract: When reed contacts are used to scan tachometer wheels, they are not as reliable as required with respect to the high operating sequences occurring in the measurement of rotational speed and speed in machines and motors, and in particular with respect to the necessary high number of make-break operations. The device is therefore constructed for scanning by means of Hall sensors or other semiconductor sensors (6) sensitive to magnetic fields in such a way that the strength (intensity) of the magnetic fields of the magnet poles (N or S) used for the scanning outweighs the strength of the magnetic fields of the magnet poles (S or N) not used. <IMAGE>

Title: Method (metal indicator detection) for the complexometric determination of oxyanions/polyanions at picomole sensitivity, use for the continuous post-column detection in liquid chromatographic separation and for detection after separation on thin layer supports
Inventor: MAYR GEORG W
IPC: G01N31/22
Filed: 1988-07-15
Abstract: The designated invention provides a new complexometric method which is suitable for detecting oxyanions and polyanions after their liquid chromatographic separation using a continuous post-column method at down to picomole sensitivity. The method of the invention is also suitable for detecting such anions separated on thin layer supports. The ternary detection principle always used in the same manner is based on the fact that polyanions and polyvalent oxyanions form, at sufficiently high pH, high-affinity complexes with a series of polyvalent cations. This complex formation can in turn be made visible (visualised) by the simultaneous presence of a cation indicator specific to the cations used. The detection signal which can be evaluated is in each case the reduction in the cation-specific signal of the indicator always when (for post-column detection) or where (for thin layer supports) the presence of competing polyanions or oxyanions has resulted in these binding a part of the polyvalent cations, i.e. the indicator substance is removed.
