Abstract: The invention relates to a method for producing stem cells having an increased development potential from somatic stem cells, wherein a tissue sample comprising somatic stem cells or a body fluid sample comprising somatic stem cells is taken from an organism, wherein from this tissue sample or body fluid sample as an option somatic stem cells are isolated and/or cultivated, and wherein the thus obtained somatic stem cells are treated with a substance modulating the methylation of the DNA of the cells or a substance modulating the acetylation of chromatin of the cells.

Abstract: A process for preparing 3-isopropyl-1H-2,1,3-benzothiadiazin-4 (3H)-one 2,2-dioxide (I) or a salt of I which comprises reacting anthranilic isopropylamide II simultaneously with sulfur trioxide or chlorosulfonic acid in the presence of an organic base or with adducts of sulfur trioxide and organic bases and phosphorus oxychloride at from 50° C. to the reflux temperature, followed, if appropriate, by conversion into its salts, is described.

Abstract: An adjuster device for a deflector fitting of a vehicle occupant restraint system is provided, which comprises a rail adapted for vehicle-fixed mounting. The rail is provided with latching openings and comprises a bottom part and two side parts. The adjuster device further comprises a sled shiftable in the rail and adapted for being coupled to a vehicle seat. The sled is provided with a fitting part for the deflector fitting and at least one latching part which is able to cooperate with the latching openings to block the sled against a downwards displacement in the rail. The latching part is translatable from a normal rest position, in which it does not engage a latching opening, into a locking position in which it engages at least one of the latching openings, by means of a force acting downwards on the fitting part relative to the rail.

Abstract: The seat belt retractor has a belt reel (12) rotatably mounted in a frame (10). A vehicle-sensitive latching mechanism includes a control disk (64) connected to the belt reel (12), rotation of which is lockable by means of the vehicle-sensitive inertial sensor (71, 71a, 73a, 75a). A belt tensioning drive engages the first axial end of a torsion bar (30), the second end of which is drivingly coupled to the belt reel (12). After belt tensioning the first end of said torsion bar (30) is blocked on the frame (10). Under the load subsequently introduced via the belt webbing (14) the torsion bar (30) is twisted about its axis for conversion of energy. The control disk (64) is connected to the belt reel (12) via a torque-limiting coupling (60, 62, 68, 74, 78; 92 to 106).

Abstract: The instant invention relates to a process and apparatus for treating wastewater containing bentazon by decomposing the bentazon therein and thus eliminating or substantially reducing the bentazon content. This process comprises adjusting the pH of the wastewater to a value of less than 7 and heating it to a temperature of at least about 60.degree. C.

Abstract: In order to preserve the solubility of films and moldings of polyvinyl alcohol in cold water even under the action of an aggressive atmosphere, in particular a strongly acidic atmosphere, the thermoplastically processable polyvinyl alcohol composition used for the preparation of the films and moldings is stabilized by the addition of a water-soluble polymer or copolymer which is composed to the extent of at least 70% by weight of monomer units which are carboxylic acid amides at least monosubstituted on the amido nitrogen. N-vinylpyrrolidine, N-vinyl-N-methylacetamide and the alkali metal salts or the ammonium salts of 2-acrylamido-2-methylpropanesulfonic acid have proved to be particularly suitable representatives of this group of compounds.

Abstract: The time required for several calibration signals to traverse a signal path (1, 2, 3) is determined and compared with a nominal value. The individual calibration signals have different values for at least one signal parameter. Depending on the results of the comparison, a control signal is produced for each value of the signal parameter. Of the intelligence signal, the value of the signal parameter to be taken into account in the determination of the control signal is measured prior to the traversal of the signal path, and the control signal assigned to this value is selected.The control signal can be used in DME transponders to set an exact transponder delay, and in DME interrogators to allow for delay variations in the distance measurement.

Abstract: Mixtures which can be cured to give crosslinked copolymerisates having valuable mechanical properties, characterized in that they compriseA. polyimides of certain unsaturated dicarboxylic acids, such as maleic acid or citraconic acid,B. indole or indole derivatives and optionallyC. a curing catalyst.

Abstract: According to the invention, polyaddition products containing imide groups are manufactured by reacting certain polyimides (preferably maleimides) with polyhydric alcohols in the presence of basic compounds. The preferred embodiment (E) relates to the use of catalysts as basic compounds. In particular, amines and alkali metal compounds can be used. A further embodiment (F) relates to the use of primary polyamines as basic compounds. In the latter case, the polyamine participates in the polyaddition mechanism, that is to say the molecules are incorporated into the polyaddition products. In this latter case, catalysts can also be used additionally.
