Abstract: A lithium secondary cell array in a cylindrical design has a winding mandrel and a winding packet, which contains foil-like coated strips and contacting strips that form the electric cell structure consisting of anode, cathode and separator. The cell array has outer electrical connections which include pole caps. The winding mandrel includes an insulating material and has a through-channel extending in the longitudinal axis direction. The winding mandrel is connected to an inner pole cap at each end, the pole caps likewise having a respective through-channel. One outer pole cap having a through-passage is respectively provided, which surrounds the winding packet circumferentially at least in the edge region, wherein several radially arranged force-fit connections, each acting between the outer and the inner pole cap, are used to fix the winding packet and achieve the electrical contacting between the contacting strips and the outer pole cap.

Abstract: A method for operating a vehicle which has at least one steered axle and at least one driven axle, wherein at least the driven axle has at least two wheel-hub electric motors that are integrated in the respective drive wheel. In addition, an electronic control unit (BLDC controller module 1, BLDC controller module 2) is provided for the wheel-hub motors (wheel-hub motor 1, wheel hub motor 2) forming an electronic differential. Sensors detect signals (Hall signals) that correspond to the driving defaults. Correction factors for default values for controlling the wheel-hub motors are determined from the sensor signals (speed), the position of the accelerator pedal (gas pedal) or accelerator throttle and the steering angle (steering angle generator) by an interface module and the factors are forwarded to the relevant motor control units (BLDC controller module 1, BLDC controller module 2).

Abstract: A spacecraft with a yaw steering system performing yaw steering. The yaw steering includes steering the spacecraft to have a yaw angle (?) for all sun elevation angles (?) in accordance with a yaw steering guidance law that provides a yaw steering motion about a yaw axis which is smooth for all sun elevation angles (?). At least part of the guidance law comprises a smoothing function (f), which is a function of an orbital position parameter (?) of the spacecraft, the smoothing function (f) smoothing the yaw steering motion for values of the orbital position parameter (?) where high rotational rates {dot over (?)} or high rotational accelerations {umlaut over (?)} would occur without the smoothing function (f).

Abstract: The present invention relates to a compression device for stimulating the efflux of a body fluid from a body part. The device has a compression unit with a pressure-application region made of a deformable material, the region being formed to generate a repulsive force between the body part and the compression unit. The repulsive force passes through a force maximum then decreases to serve as an indication that the body part is guided sufficiently firmly and far enough onto the compression unit.

Abstract: In a method for maintaining the orbital position of a geostationary satellite by compensating perturbational effects of interfering influences, a range of the satellite orbit is determined, relative to a space-fixed reference system, in which the perturbational effects on the satellite position by the interfering influences reaches a maximum. Position maintaining actuators of the satellite are activated within the determined range.

Abstract: Process for the batch purification of uranium recovered in a reprocessing process, after a first separation of impurities, in which for each batch an aqueous, nitric acid uranyl-nitrate solution (UNH original solution), which still contains residual amounts of impurities, is cooled to crystallize out purified UO.sub.2 (NO.sub.3).sub.2 .multidot.6H.sub.2 O (UNH) from the solution and the resulting crystals are separated out of their mother liquor and washed. The original solution is adjusted to a specified uranium concentration and the adjusted solution is cooled to below 0.degree. C. to bring about the crystallization. The duration between starting and ending the crystallization is held between 0.1 and 10 hours. The amount of the UNH crystals which is crystallized out corresponds to at least about 80 weight % of the uranium content introduced. The ratio of the volume of the crystals formed to the volume of the remaining mother liquor is not larger than 0.5.

Abstract: A process for the separation of substances hindering the recovery of the fissionable materials uranium and plutonium and for the separation of the fissionable materials to be recovered in a reprocessing process for spent, irradiated nuclear fuel- and/or fertile materials. A second and a third wash of the organic phase is performed for residual ruthenium separation and residual zirconium separation, and there is a repetition of the Pu stripping step with simultaneous electrolytic reduction of Pu(IV) to Pu(III). The second and third wash solutions or the aqueous phase employed for the repetition of plutonium stripping, respectively, each contains a high concentration of product uranyl nitrate. The aqueous run-off from the second and third washes and from the repetition of the Pu stripping step is indirectly fed back into the aqueous fuel solution employed in the first extraction step of the reprocessing method by first feeding these run-offs to an intermediate treatment.
