Title: Process for separating off heavy metals
Inventor: FRIEDMANN HANS DIPL ING
IPC: B09B3/00
Filed: 1993-02-13
Abstract: The invention relates to a process for separating off heavy metals from contaminated material, in particular from disperse solids, soils, organic wastes, sewage sludge and the like. According to the invention, the process comprises the following steps:   a) addition of degradable organic substance and water to the material contaminated with heavy metals; b) mixing of the resulting suspension with exclusion of oxygen and increasing the solubility of the heavy metals by lowering the pH of the suspension by means of the organic acids which form from the organic substance by means of microorganisms with the exclusion of oxygen and transfer of the heavy metals into an aqueous phase; c) separation of the now predominantly heavy metal-free material from the heavy metal-containing aqueous phase; d) introducing the heavy metal-containing aqueous phase into a biogas reactor; e) lowering the solubility of the heavy metals in the aqueous phase by biodegradation of the organic acids being formed in process step b) in the biogas reactor with exclusion of oxygen, sparingly soluble heavy metal compounds being formed; and f) separating the sparingly soluble heavy metal compounds from the now heavy metal-free aqueous phase.

Title: Process for reducing the emissions from furnaces, incinerators and exhaust air systems and for combined elimination of contaminants in pollutant gases and waste waters
Inventor: KRUEGER REINER
IPC: C02F3/32
Filed: 1993-02-25
Abstract: The object of the invention is essentially to avoid the direct emission of pollutant gases into the atmosphere, to very largely eliminate the contaminants contained therein, if required together with the contaminants in waste waters, with an efficiency which is independent of the amount of contaminant emitted, and to replace the conventional pollutant gas purification processes by the present process. This object is achieved according to the invention by the process scheme depicted in Figure 1 for combined reduction and elimination of emission for pollutant gases and waste waters, the mode of operation being as follows: A water jet diffusion pump operated with fresh water, ground water, prepurified or purified waste water or combinations thereof draws in the pollutant gases which are dissolved in the water, are diffused, entrained and passed into the solvent converter (8) from where the water, with the pollutant gases dissolved therein, for the purpose of breaking down contaminants, flows off, together with the mechanically pretreated domestic or industrial waste waster, into a plant-root sewage treatment system (reed bed) (16, 17). The treated waste water is passed back, as required, via a return line (23) into the solvent converter (8). <IMAGE>

Title: Process for the production of soda
Inventor: WOLF BODO DR ING
IPC: C01D7/18
Filed: 1993-02-25
Abstract: The invention relates to a process for producing soda (sodium carbonate) by double decomposition of common salt (sodium chloride) and limestone (mass exchange) by the Solvay process with the aid of ammonia. It is proposed that the waste gas inherent in the process from the wet part be reduced by the lime burning gas which is used for the production of soda being produced in the lime burning process using technical-grade oxygen in place of air. The waste gas mass of the wet part of the soda process which has been reduced in this way is, according to the invention, fed by means of air or waste air from the filtration of the bicarbonate suspension to that part of the lime burning process which gives off its lime burning gas to the surroundings. The economic importance of the invention lies in the avoidance of ammonia emissions inherent in the process and connected with the gas and the possibility of increasing performance in existing plants of the wet part of the soda works by increasing the carbon dioxide partial pressure in the lime burning gas.

Title: Method and device for determining the optimum pulse value
IPC: A61B5/024
Filed: 1993-09-02
Abstract: The invention relates to a method and a device for determining the optimum pulse value. The main fields of application of the invention are as follows:     - health and sports training,   - check of the condition of the human body.   The optimum pulse value is determined on the pulse curve which is the equation of the regression. The pulse curve approximates the recorded values of the time between contraction of the heart during performance of work with steady output. On this curve, the pulse values in the given instant with the minimal time delay and the optimum pulse value at which the cardiovascular system and the entire human body work with maximum efficiency can be used to estimate the condition of the human body. The optimum pulse value is the individual, genetic predetermined parameter of the human body. Its value remains the same all through life. It is merely subject to age-related changes caused by ageing of the body or by pathological changes in the heart. The device for implementing the method of determining the optimum value comprises the following basic parts: electronic device with the microprocessor or PC, cardiac contraction sensor, recording and displaying means.
