The invention relates to a biomass gasifier for the gasification of renewable raw materials. A biomass gasifier which generates a comparatively pure product gas with only low level impurities which can, for example, be used in an internal combustion engine can be achieved by means of a biomass gasifier with the following features: a biomass gasifier with a rotating tube reactor (10) which may be rotated about the longitudinal axis thereof, a first front face (24) of the rotating tube reactor (10) having a first and a second opening, whilst a second front face (26) of the rotating tube reactor (10) has a sealed embodiment, with an externally mounted heating device (12), with a biomass supply line (20), opening out into the rotating tube reactor (10) through the first opening in the first from face (24) and with a residue extraction line (30), which extends into a reaction zone (28) in the rotating tube reactor (10) through the second opening in the first front face (24), the residue extraction line (30) being designed such as to remove both the residue and the product gas from the rotating tube reactor (10).

The invention relates to a bridge construction (1) comprising a load-bearing structure (20) that has at least one approximately triangular cross-sectional shape. The catheti (22, 23) of the at least one triangular cross-sectional shape which extend at an angle from the horizontal are embodied as load-bearing shells in the longitudinal direction of the bridge construction (1), said load-bearing shells being configured in a curved manner in the direction of the cathetus (21) that extends horizontally.

The invention relates to a method for the continuous reduction of the odor pollution caused by the waste water in sewers, comprising the following steps: a) determining the actual pollution of the waste water by means of a water sample of the waste water, b) calculating the quantity of odor-reducing agent required to reduce the odor pollution below a defined threshold value, using the degree of pollution, c) adding the defined quantity of odor-reducing agent to the waste water, d) continuously repeating steps a) to c). The aim of the invention is to devise a device and a method of the above type for reliably detecting odor pollution and for reducing it to a minimum using the odor-reducing agents. For this purpose, in step a) the pollution of the waste water is determined by determining the pollution of the water sample with odorous substances.

A device is disclosed for checking for the presence of at least one object. According to the invention, the points in time and/or the frequency of polling cycles which serve for checking for the presence of the at least one object are automatically adapted to the momentarily prevailing context. The device comprises for that purpose context recognition means (9), adaptation means (10) and sensors (13, 14, 15) which supply context information.

The present invention relates to a method for treating a steel strip, particularly a steel strip made of highly resistant heat-treated steel, by cold rolling. The inventive method comprises at least a first step of heat treatment consisting of recrystallization annealing and at least another subsequent step of heat treatment consisting of hardening. Said method is characterized in that the time-temperature curve during the first step of heat treatment is chosen in such a way that only a partial recrystallization takes place and that the elongated structure produced by the previous strain-hardening is partially conserved. The inventive method enables reducing significantly the annealing time and annealing temperature during recrystallization annealing while at the same time reducing the annealing time during shape hardening. The processing chain can be reduced by more rapid annealing cycles, the reduction of the annealing temperature leading to significant energy savings. Said method allows producing e.g. semifinished sheet metal products for vehicle body components having an optimized strength/elongation ratio.

A description is given of a method for reflection of radiation (5) in the EUV or X-ray wavelength range with the application of at least one reflective interface (3) a first material (2) having a first refractive index (n1) being provided on a side of the interface (3) that is intended for the incidence of the radiation (5) , and a second material (1) having a second refractive index (n2) being provided on that side of the interface (3) which is remote from the incident radiation (5), and a preselected angle (&agr;i) of incidence being used for the incident radiation (5). According to the invention, in the case the wavelength range of the radiation (5) used, the first refractive index (n1) is greater than the second refractive index (n2). Moreover, for the radiation (5) an angle (&agr;i) of incidence is chosen which is greater than 0 and is less than the angle (&agr;c) of total reflection at most by an amount such that the total reflectivity at the interface (3) for the wavelength range chosen is greater than at an angle of incidence &agr;I = 0°. In addition, a description is given of a method for producing a material which is particularly well suited to the method according to the invention, and a device suitable for EUV lithography and for the masking technique (Figure 1).

The invention relates to a method for applying an adhesion promoter to a fibrous material, in particular, during the production of fiber composites with a thermoplastic or duroplastic matrix. The aim of the invention is to provide a method with which, without the described drawbacks of existing methods, the adhesion promoter can be directly applied to the fibrous material. To this end, the fibrous material, together with the adhesion promoter, is conveyed inside a pipe at a speed greater than 20 m/s.
