Abstract: A process and an apparatus for preparing and carrying out NMR measurements on substrate samples (3.1), individual solutions of the substrate samples (3.1) being prepared by means of a pipetting system (1) and being fed to a flow cell (16) for preparation and carrying out of NMR measurements, it being possible to flush the feed apparatus (7) and the pipetting system (1) with at least one solvent (8, 9) are described. A workstation (54) recording the NMR spectrum of the sample and a computer (53) controlling the pipetting system (1) access a common directory tree (32) which contains directories (33.1 to 33.9) with files which define the samples and are called up in such a way as to ensure that the directories (33.1 to 33.9) are worked through in a time-interleaved manner.

Abstract: In a process for the temporary protection of plastic articles, particularly plastic mouldings, against electrostatic charging and a contamination or dirtying associated therewith, the plastic article is at least partly provided with a coating, which contains an antistatic and which can be washed off with water and/or at least one organic solvent. The antistatic is in particular an electrically conductive, organic polymer. The coating is in particular applied to the plastic article in the form of a solution. The invention also covers a composition, particularly a solution, which contains at least one antistatic and at least one solvent. The antistatic is in particular an electrically conductive, organic polymer, whilst the solvent is in particular a mixture of water and organic solvents.

Abstract: In a water treating apparatus the water is passed over a plurality of stages to a lower plane, each stage having a water trough, a section for the free fall of the water, and a catch. This makes possible the intensive mixing of the water with components of the air, especially oxygen and amino acids, as well as the action of natural light radiation onto the water.

Abstract: In order to obtain better noise protection, longer service life of machine and tools, and to increase the productivity of wire shaping apparatuses, in particular, a universal spring winding machine with a cutting device (16) consisting essentially of a movable cutting tool (38) with drive (80) and a stationary cutting tool (150) at which the endless intaken wire is cut, this invention suggests:to conceive the drive of the cutting tool (38) in the form of a fluid operated cylinder piston aggregate cutting cylinder (80) with program-controllable NC valve (78);to fix the movable cutting tool (38) by means of an adapter (158) to the movable part of the aggregate (piston rod 154);to bring the moving direction of the latter (154) into accordance with the shearing direction of the movable cutting tool (38).

Abstract: 1-Nitroanthraquinone-2-carboxylic acid of the formula I ##STR1## is prepared by treating novel 2-substituted 1-nitroanthraquinones of the general formula II ##STR2## where R is --CH.dbd.CH--R.sup.1 or --CH.sub.2 --CHO, where R.sup.1 is C.sub.1 -C.sub.5 -dialkylamino or a cyclic 5- or 6-membered amine which may contain further hetero atoms, with oxidizing agents free of heavy metal.

Abstract: An impact protection system for an occupant of a motor vehicle with a prefabricated constructional unit that is fastened at parts of the vehicle body and which includes a generator housing, a base plate, a gas cushion, a generator and a cover provided with a tearing seam, is provided with a receiving frame that is adjustably connected with a support part of a dashboard. The prefabricated constructional unit is fastened at the receiving frame. The support partg delimits a recess of the dashboard that is closed off by a recess cover. The cover, via a releasable snap-in connection and an additional fastening, interacts with the receiving frame such that when the gas cushion unfolds, the snap-in connection opens up and the cover, via a desired bending point formed by the receiving frame, is swivelled preferably upward in the direction of a windshield.

Abstract: A paneling member for the interior of automotive vehicles, especially a dashboard, is constructed of at least two covered polyurethane foam portions which are provided with a stiffening support element embedded in the foam. The foam body portions have different weights per unit volume and compressive strengths and, accordingly, different degrees of hardness. A relatively firm foam body with an ABS or PVC sheet covering is used for the upper portion of the paneling member. A softer foam body with a covering selected from one of a variety of materials is used to form the lower portion of the paneling member.
