Abstract: A process for the production of pig iron from fine ore is produced, in which the fine ore is prereduced in one or more reduction units (1, 2). The resulting sponge iron is subsequently melted down and finally reduced in a melt-down gasifier (3) with the aid of at least one plasma burner (9) and a solid carbonaceous reducing agent. The sponge iron is fed into the lower part of the melt-down gasifier in the vicinity of the plasma burners, preferably directly over the latter, above the collecting melting bath and slag. The solid carbonaceous material, particularly low grade coal required for final reduction is fed from above (18) into the melt-down gasifier. It is converted in the latter into coke and forms in the lower part of the gasifier a fluidized bed, which is maintained by the plasma gas, additionally introduced oxygen and CO formed during final reduction.

Abstract: A method and apparatus for measuring the overlayer of a nonmagnetic material such as concrete and the diameter of steel reinforcement bars embedded therein. A steady state magnetic flux field is generated in the area of the concrete which is to be tested. A reinforcement bar embedded within the concrete generates a scatter field which is superimposed on the excitation field. By scanning the concrete surface, an amplitude locus is determined which is subtracted from an amplitude locus determined in the absence of ferromagnetic objects, whereby a difference locus is obtained. The concrete overlayer and the diameter of the steel reinforcement bar are determined from the location and magnitude of the maximum values of the difference locus with the aid of an evaluation computer.

Abstract: The instantaneous braking press of a vehicle and the speed of a wheel are measured continuously. The coefficients of a linear differential equation relating wheel speed and braking press, are estimated from normalised values of the wheel speed and braking press, at each sampling time using known identification algorithms. The coefficient of frictional content is derived from the coefficients of the differential equation and the normalised wheel speed taking account of the moment of inertia, wt. and size of the wheel.
