Abstract: An underbody cladding is provided for a two-track motor vehicle with wheel-controlling links as part of a rear axle for cladding the underbody. The underbody cladding at least partially extends in a substantially horizontal plane and extends in the direction of the outside of the vehicle close to an inner side of a rear wheel. The underbody cladding is divided into three sections, a front section, a central section and a rear section. The central section extends at least over a region below the wheel-controlling links and is connected at least over part of the width thereof to the front section and/or the rear section. The central section is designed in such a manner that the section can at least partially follow and/or yield to a vertical movement of the wheel-controlling links. The front and the rear section of the underbody cladding can in each case be arranged in a positionally fixed manner on the motor vehicle and cannot follow and/or yield to a vertical movement of the wheel-controlling links.

The underbody panelling part can be pivoted about the first mounting point when the wheel carrier is pivoted. A subassembly having the underbody panelling part is also provided.

Abstract: An underbody panelling part of a wheel axle near the wheel arch of a motor vehicle has a main part, the covering surface of which is variable, and a fastening structure for fixed connection to the body and/or a fastening structure for fixed connection to a transverse link of the motor vehicle. In the mounted state the covering surface can be varied with the steering angle.

Abstract: An electromechanical brake power assist unit of a vehicle braking system has a master brake cylinder with a piston rod, displaceable by a brake pedal and, in the process, building up brake pressure. The piston rod is also displaceable by an electric motor. The piston rod is supported on a pedal lever, which is formed by the brake pedal itself or an intermediate element pivotable about an axis of rotation by the brake pedal. The piston rod is displaced by a pivotal movement of the pedal lever. An axis of rotation of the pedal lever is displaceable by the electric motor in a moving direction of the piston rod.

Abstract: Methods for generating a purified catalyst are provided. The method includes performing a reaction in a reaction vessel to generate a liquid catalyst and reaction products, purging the reaction products using an inert gas to form a purged catalyst, freezing the purged catalyst in the reaction vessel, and applying a vacuum to the reaction vessel while the purged catalyst thaws, wherein the vacuum removes residual reaction products to form a purified catalyst. Systems for generating a purified catalyst and a purified catalyst are also provided.

Abstract: The invention relates to known housing seals of two housing parts lying against each other, a first housing part (1) having a first sealing surface (6) and a second housing part (2) having a second sealing surface (7), which housing seals are equipped with a seal (15), which is inserted into a groove (10) in the first sealing surface (6) of the first housing part (1), wherein the groove (10) is covered by the second sealing surface (7) of the second housing part (2). According to the invention, in order to prevent crevice corrosion, the groove (10) has an opening (11) between the sealing surfaces (6, 7), which is used to ventilate the groove (10) having the inserted seal. The invention is intended for water pumps, in particular for auxiliary water pumps of motor vehicles.

Abstract: A method of making a heterogenously supported catalyst useful in dimerization, oligomerization or polymerization is provided in which a catalyst precursor containing a metal and an aromatic group are alkylated onto an oligomeric support having at least one terminal unsaturated group by Friedel Crafts alkylation.

Abstract: Methods and apparatus relate to treating hydrocarbons recovered with steam condensate from a formation. The treating removes particulates from the hydrocarbons by addition of a flocculant to produced fluids containing the hydrocarbons and an aqueous phase with the condensate. The flocculant causes the particulates suspended in the hydrocarbons to agglomerate and be transferred to the aqueous phase, which is then separated from the hydrocarbons.

Abstract: A vehicle wheel suspension is provided having a hydraulic vibration damper, which is connected in parallel to a suspension spring which proportionally supports the vehicle body. A rebound spring is provided, which preferably and typically becomes effective in the event of larger spring deflection distances. The support point of the rebound spring is displaceable in relation to the damper housing by way of a spring support piston, which is provided therein and is displaceable by fluid externally supplied with pressure via pump. In this case, the pump is connected to a pressure accumulator for the fluid and delivers fluid out of the pressure accumulator into the damper housing or out of the damper housing back into the pressure accumulator. The absolute value of the spring constant of the pressure accumulator is at least in the order of magnitude of the spring constant of the associated suspension spring or springs, or is greater.

Abstract: The present embodiments relate to a beam head including a vacuum housing, in which an electron source is arranged. The beam head also includes a beam finger that is connected to the vacuum housing and has an outlet window at a distal end. The beam head includes a transformer housing, in which a transformer connected to the electron source is arranged. The transformer housing is arranged directly on the vacuum housing.

Abstract: A spindle drive having a threaded spindle driveable in a rotational fashion, a carriage adjustable via the threaded spindle along a guide rail, and several guide carriages arranged in front and behind the carriage in the feed direction to support the spindle, with the guide carriages arranged in front of the carriage in an accumulating motion being pushed together successively by the carriage towards the spindle end, and with the guide carriages arranged behind the carriage being entrained by a coupling mechanism and moved into allocated support positions. Coupling elements are provided on the guide carriages and the carriage, that cooperate together and can be operated by switching elements fixed on the guide rail, by which the guide carriages arranged in front of the carriage are automatically coupled during the successive displacement motion, and by which the entrained guide carriages upon reaching their support position are automatically decoupled and fixed.
