Polyurethane gel foams are proposed as is their use in modern wound treatment. In particular, wound dressings comprise polyurethane gel foams for treating moderately to severely exuding wounds. The polyurethane gel foams are thereby produced from an isocyanate component A having a functionality f of fB≦3, a polymeric polyol component B having a functionality f of fB≦6, and a polysaccharide C, comprising at least one uronic acid or a salt thereof, wherein the ratio of the number of isocyanates groups of the isocyananate component A to the total number of hydroxyl groups, carboxy groups and carboxylate groups in the polymeric polyol component B and the polysaccharide C corresponds to the ratio 1:2 to 1:30.

The invention relates to methods for determining a motion vector in a predetermined area of a sequence of digital images by comparing a current image to a preceding image. The current image and the preceding image are prepared by the same filter for image adaptation. Distance vectors between a pixel of a current image and balanced pixels of the preceding image in a predetermined environment are determined, said distance vectors being averaged in order to form a displacement vector for the pixel. The displacement vectors are averaged and the displacement vector is produced.

The different electrical components and cables arranged in the B flange of an electric motor can be installed only with difficulties and are complicated and time-consuming due to the restricted space conditions in the B flange. In order to improve this, it is proposed to recess the B flange's 3 front side 10 facing away from the electric motor 1 at least in sections with respect to an imaginary surface normal to the longitudinal axis 15 of the electric motor 1 in the direction toward the motor housing 2, and to shape the B flange cover's 9 front face resting against the B flange 3 in a mirror-inverted manner to thereby improve the accessibility to the inside of the B flange 3.

Process for the production of synthesis gas (3), in which methane and carbon dioxide (2) are introduced into a reaction space (R) and reacted in the presence of a solid (W) at elevated temperatures to give hydrogen and carbon monoxide. Methane and carbon dioxide are passed through a carbon-containing granular material (W) and reacted in a high-temperature zone (H).

The invention relates to a process for parallel preparation of hydrogen and one or more carbonaceous products, in which hydrocarbons are introduced into a reaction space (R) and decomposed thermally to carbon and hydrogen in the presence of carbon-rich pellets (W). It is a feature of the invention that at least a portion of the thermal energy required for the hydrocarbon decomposition is introduced into the reaction space (R) by means of a gaseous heat carrier.
