Abstract: The invention relates to a process for removal of sulfur compounds from wastewater, which process provides recovery of elemental sulfur. The process is carried out in two separate anaerobic reactors. In the first reactor organic compounds are converted to acid compounds and sulfur compounds are converted to sulfide compounds. The sulfide compounds are stripped from said first reactor with a stripping gas. Subsequently, the effluent of the first reactor is fed to a second anaerobic reactor, in which organic compounds, such as the acid compounds, are converted to produce biogas, while any unconverted sulfur compounds from the previous step are converted to sulfide compounds as well. Finally, the sulfide compounds are removed from the second reactor in a stripping system, and converted to elemental sulfur in an adsorber.

Abstract: A device for measuring the volume flow of a fluid in a pipe comprises at least two objects to be arranged in the pipe. By means of sensors, the frequencies can be determined with which vortices occur which arise behind the respective objects upon the fluid flowing round the objects. The objects are of so different a shape and/or diameter that at least one of the vortex frequencies thereby determined is independent of a pulsation frequency possibly arising in the approach velocity of the fluid. A sensor is present for determining this pulsation frequency, while further means are present for determining the approach velocity from that vortex frequency or those vortex frequencies for which it holds that the ratio between the vortex frequency and the pulsation frequency lies outside an interval (0.4, 2.5).

The system comprises a computer for measuring parameters of the combustion of the matter, wherein use, matter, such as for instance waste, is supplied to the system and combusted, thereby forming a flue gas. The system further comprises means for determining the concentration of CO2, O2 and H2O in the flue gas. The computer is arranged for determining, on the basis of the measured concentrations, the rate of combustion and/or the composition of the combustible part CHyOz of the waste supplied to the system, for the purpose of process control.

Abstract: The present invention relates to the gene PLOD2 which codes for telopeptide lysyl hydroxylase (TLH). This enzyme converts telopeptidyl Lys into telopeptidyl Hyl, that can subsequently be converted into hydroxyallysine cross-links. Collagen with hydroxyallysine cross-links shows a higher resistance to degradation by proteinases than collagen with cross-links derived from allysine.

Abstract: The system for continuous thermal combustion of matter, such as waste, comprises an incinerator, air supply means for supplying heated air to the incinerator, and a steam generator for generating steam on the basis of heat generated in the incinerator. The system further comprising a controller which generates at least one control signal for setting the magnitude of a supply stream of the amount of material to the incinerator and/or for setting the amount of air which is supplied to the incinerator by means of the air supply means. The controller controls the at least one control signal, such that by the steam generator an amount of steam per unit time is generated which is equal to a first value and/or that by the air supply means so much air is supplied that an amount of oxygen is present in the incinerator which is equal to a second value.

Abstract: A door structure has a first plate with an opening enclosed by a peripheral edge and a door connected to this first plate by a hinge construction, which first plate carries a number of clamps which are simultaneously rotatable by an operating mechanism with an operating handle and through rotation can co-act with the peripheral surfaces of corresponding non-round continuous holes in the door. The peripheral surfaces each have a contact surface inclining relative to the main plane of the door structure, and the continuous holes have a form such that the clamps can pass therethrough. The peripheral edge is deformable under the influence of an air pressure pulse acting on the door structure in the closed position such that at least the door can be pressed out of the main plane it occupies when the door structure is in the closed position while maintaining the sealing co-action between the door and the peripheral edge, and the mechanical integrity of the door structure.

Abstract: Method and apparatus for processing a watery substance, such as sludge or manure, wherein in a mixer-drier (33) the watery substance to be processed, which may or may not be mechanically partly dewatered (in 31) and/or preheated (in 32), is mixed with zeolites of type A, which adsorb water from the watery substance while releasing adsorption heat which causes an amount of moisture to evaporate, while from the mixer-drier vapor and a mixture of zeolites and dried matter are discharged, whereafter the zeolites are regenerated in an oven (35) through heating, and are returned to the mixer-drier after being separated from dry matter residue formed by the heating, such as ash, and released moisture. Prior to the supply to the oven, at least a part of the dried matter can be extracted by a separation device (34) the mixture formed in the mixer-drier.

Abstract: The present invention describes two novel proteins having fructosyltransferase activity. Both enzymes are derived from lactobacilli, which are food-grade microorganisms with the Generally Recognized As Safe (GRAS) status. One of these proteins produces an inulin and fructo-oligosaccharides, while the other produces a levan. According to the invention lactobacilli capable of producing an inulin and/or a levan and/or fructo-oligosaccharides using one or both of the fructosyltransferases can be used as a probiotic or a symbiotic.

Abstract: The application relates to a process for working a workpiece, in which process an abrasive liquid is sprayed onto the workpiece, via a nozzle, at relatively low pressures which are sufficient to shape and/or polish the surface of the workpiece. The workpiece can be both shaped and polished in a single working step. Abrasive particles or polishing particles may be contained in the abrasive liquid. The pressure of the abrasive liquid lies below 50 bar, preferably below 20 bar. By arranging two nozzles in such a manner that the liquid jets intersect one another at a point, it is possible to set an accurate working depth.

Abstract: A diesel powered vehicle is provided with an SCR system which uses an external reducing reagent to convert NOx emissions in a manner which accounts for the effects of NOx transient emissions on the reducing catalyst. Actual NOx emissions produced by the engine are filtered using a variable NOx time constant in turn correlated to the reductant/NOx storage capacity of the reducing catalyst at its current temperature to account for changes in the SCR system attributed to NOx transient emissions. Catalyst temperature is filtered using a variable catalyst time constant corresponding to current space velocity of the exhaust gas to account for changes in the catalyst temperature attributed to NOx transient emissions. The reductant is metered on the basis of the filtered, corrected NOx concentration applied at a NSR ratio based, in turn, on the filtered, corrected reducing catalyst temperature.
