Granted: 1995-07-09
Abstract: FIELD: mining processes. SUBSTANCE: active and passive modes of leaching process in reservoirs is of predetermined length. In so doing metal precipitation from producible solution into difficulty soluble precipitate is excluded. Number of reservoirs is preset with the proviso that time of longer passive leaching mode in one reservoir is equal to time of shorter active leaching mode in integer-valued number of reservoirs. Then volume of agent solutions taking part in leaching process is reduced by successive transferring agent solution from one reservoir, where the process has been completed into another one. In so doing, metal content in resultant agent solution is increased, and hence, sorption effectiveness, and ecological purity of the process are increased too. A formula for calculating needed number of reservoirs is presented, as well as criterion for finishing leaching process. Use of the criterion prevents nonproductive use of agent solutions and increases method productivity. EFFECT: increased efficiency of leaching and sorption processes at the expense of considerable reduction of time for saturation ores with agent solution without increasing solution volume, as well as decreased volume of washing out and rendering harmless solutions. 5 dwg

Patent DE-19602862-C1 (DE)
Inventor: BECKER MICHAEL DR
IPC: G01N21/55
Filed: 1996-01-28
Granted: 1997-07-17
Abstract: The invention aims to simplify the design of the known conoscopic measurement devices (10) used for determining the viewing angle-dependent contrast in particular of transmission-operated liquid crystal displays, and to calibrate such a measurement device spectrographically and make it more versatile. This is done according to the invention by dispensing with the conventional projection optics (for forming an image of the interference pattern on a detector array) and making use instead of relatively few individual rapid detectors (18) for spectrally integrating and/or spectrally analysing light measurement. These detectors are connected, directly or as directly as possible via optical waveguide devices (20) in the interference plane to point surface elements in the interference pattern selected according to the angle of view. When optical waveguides (20, 20') which branch off to different detectors are connected, completely different direction-dependent measurements can be made and recorded at precisely the same time and for identical angles of view, as can (in addition to the contrast measurements) saturation measurements and measurements of dynamic switching characteristics.

Patent DE-19943082-C1 (DE)
Inventor: THEIL HERMANN
IPC: E04H12/34
Filed: 1999-09-09
Granted: 2001-02-08
Abstract: The invention aims at ensuring the form and stability of cylindrical or straight prismatic towers during the sliding operation. To this end, the reinforcement structures for the final state such as the horizontal spoked wheels are temporarily integrated into the sliding mold and simultaneously used for other provisional structures. In the case of very high towers, for instance chimneys for upwind power stations, cooling towers and silos requiring several reinforcements, the top reinforcement for stabilizing the free crown is integrated into the sliding mold and used as a base for the lifting device of the lower reinforcements. The latter are lifted as a packet, the lowermost reinforcement being left at a predetermined height and connected to the reinforced concrete shell. The reinforcement fixed to the sliding mold protects the geometrical form and provides the required rigidity to the finished reinforced concrete shell, for instance, in case of load due to wind pressure. It can be used as contact surface for the upper stations of the cable-guided elevators and for the supporting structure of the horizontal bucket transport system as well as for the distribution of material on the perimetry.
