Title: Process for producing light workpieces which are stiff to flexure and torsion (bending and twisting) as metal-ceramic composites
Inventor: WACKER JOSEF DIPL ING
IPC: C23C4/00
Filed: 1993-03-30
Abstract: In the process of the invention, a base body (G1) having a shape corresponding to that of the desired workpiece is first produced from metal. Subsequently, the base body (G1) is provided, at least in regions which are particularly stressed mechanically, with a reinforcing layer (V1) of ceramic to increase the stiffness. Owing to the high modulus of elasticity (Young's modulus) of the ceramic, the reinforcing layer (V1) can contribute to a high degree to a high flexural and torsional strength of the finished workpiece (W1). At the same time, the reinforcing layer (V1) makes possible simple construction of the base body (G1). Since ceramic, for example in comparison with steel, has a specific gravity which is about 4 g/cm<3> lower, the total weight of the workpiece (W1) as a metal-ceramic composite can be significantly reduced in comparison with construction completely of steel. The process of the invention is preferably used for producing portals (travelling bridges) for positioning and placing systems. <IMAGE>

Title: Process for regenerating exhausted metal-salt- and/or metal-oxide-containing solutions, in particular mixed acids
Inventor: RITUPER RAFAEL DR
IPC: C23F1/46
Filed: 1993-05-10
Abstract: The invention relates to a process for regenerating exhausted metal-salt- and/or metal-oxide-containing solutions, in particular mixed acids, in which the solutions are heated and the metal fluorides and metal nitrates are pyrohydrolysed in the course of this, while the water and the free acid vaporise and the acid is recovered from the gases. In order to utilise the advantages of the known process, but simultaneously to avoid its disadvantages, the pyrohydrolysis is performed in a fluidised-bed reactor at a temperature of about 500-1000 DEG C and the metal oxides formed in the fluidised bed are granulated and taken off from the fluidised-bed reactor as dust-free, free-flowing granules, while the gases are dedusted, cooled and then fed to an acid recovery plant. <IMAGE>

Title: Method for testing the coating of metal-coated wire
Inventor: KELB WERNER DIPL ING
IPC: G01N27/90
Filed: 1993-06-23
Abstract: A method is described for testing the coating of metal-coated wire with the aid of the eddy-current method, by passing the wire to be tested through a coil arrangement and exposing it to a high-frequency alternating magnetic field which generates eddy currents in the test object, the inductive feedback of which eddy currents to the coil arrangement is evaluated with regard to amplitude, the frequency of the alternating magnetic field being selected such that the penetration depth of the eddy current into the wire is essentially limited to the thickness of the coating. By selection of the frequency of the alternating field, which is in the range of 0.1-10 MHz and is chosen towards the higher values with decreasing thickness of the coating, testing only of the coating of a metal-coated wire is achieved, without the actual wire core being involved in the testing. In addition to the amplitude evaluation of the inductive feedback of the eddy currents to the coil arrangement, a phase evaluation of this inductive feedback can be carried out, in order to determine the depth of established damage. With increasing depth of the damage, the phase angle of the eddy currents shift in comparison with the phase of the applied alternating field.
