Abstract: The invention comprises an information carrier on which the position of a measuring point (37, 41) may be determined using a mobile readout device, as well as an attendant method of determining a position wherein the information carrier features a surface onto which a visible primary information has been applied, in the manner of a book or a geographic map, wherein at least one machine-readable pattern has been printed on the surface, said pattern coding a position information, which upon bringing to bear methods of image analysis and of local sampling of parts (36, 40) of the surface, will allow a determination of position for a measurement point (37, 41) and wherein the pattern coding the position information is transparent in such a way that the primary information on the surface remains visible.

Abstract: The invention relates to a method for the separation of methyl mercaptan from reaction gas mixtures obtained by means of the catalytic conversion of H2S with methanol, by means of converting the methyl mercaptan into MMP in the presence of the byproducts with acrolein, and separating the same.

Abstract: The invention relates to a method for filling apparatuses for chemical production with solids using a controllable metering device, and an apparatus, displaceable from place to place, for carrying out the method. The apparatus is suitable in particular for filling heat exchangers, absorption columns, distillation columns or tube-bundle reactors with solids.

Abstract: A method for setting a predetermined travel of an actuator (1), in particular a piezo-electric actuator (1) for an injector of an injection system is disclosed. According to said method, a first electric state variable (Q) of the actuator (1), which determines the travel of the actuator (1), is set. Said first electric state variable (Q) is set in accordance with the temperature (TAKTOR) of the actuator (1), to avoid temperature-induced fluctuations of the actuator travel.

Abstract: A process for the preparation of nicotinic acid by the direct oxidation of &bgr;-picoline in the gas phase, wherein water and &bgr;-picoline are fed separately to the catalyst bed and the catalyst is based on a titanium dioxide support which has been prepared by the sulfate method and has a high specific surface area and a vanadium oxide content of from 5 to 50 %.

Abstract: A method and a product is provided for reducing the reduction disintegration of iron ores and iron ore agglomerates. The raw iron ores or iron ore agglomerates are treated with materials containing halogen and preferably with halogenide solutions. The degree of the improvement of reducing disintegration in a reduction furnace such as a blast or low shaft furnace at temperatures from about 400 to 600 degrees centigrade depends on the concentration employed. The type of reagent has its particular effect, because the reagents contain stochiometrically different high proportions of halogens. It is found that reduction disintegration declines with the increased halogenide concentration in the pieces of ores or agglomerates employed. In order to minimize the amount of extraneous materials introduced, the lowest possible concentration is advantageously determined for each burden component.
