    摘要: In the purification of an ammonium fluoride solution containing silicic acid by adding iron (III) ions and precipitating the iron (III) ions at a pH above 8.5 and a concentration of free ammonia in the solution of more than about 1% by weight, the silicic acid being carried with the iron (III) ion precipitate, the improvement which comprises adding the iron (III) ions to the ammonium fluoride solution at a temperature below about 30.degree. C. and, before removal of the precipitate, to the solution a salt of at least one of the alkali metals, alkaline earth metals, zinc, aluminum and lead in such quantity that the solution becomes saturated with such salt.

    摘要: A method is disclosed for performing a clinical study on a patient. The study-related or patient-related data is stored in a memory during the study. The memory is readable by a physician who is foreign to the study and is associated with the patient. An information system for a clinical study on a patient encompasses a memory for study-related or patient-related data, which is allocated to the patient, a data input device for storing data in the memory, and a data reading device for reading out the data from the memory. The data reading device is accessible to a physician who is foreign to the study and is associated with the patient.

    摘要: A device for additive-free, catalytically induced oxidation of solid carbon particles and decomposition of chemical compounds, comprising a converter chamber with compartments, in which porous structure catalyst carrier matrix profiles are mounted, so that a space between the internal diameter of catalyst profiles is connected to an inlet connection of the converter chamber, and a space around the external diameter of the catalyst profiles is connected to an outlet connection into the catalyst chamber. The profiles are mounted so that gas particles reach outlets only by passing through porous profiles. Advantageously, a third opening through which liquid, gaseous media, e.g., NO2, O3 or H2O or auxiliary means maybe in front of the porous structures. The porous structures are made of catalytically active material with catalytic action at temperatures below 400° C., preferably below 350° C. and especially below 300° C. The low-temperature below 250° C. by H2O is preferred.
