    Abstract: An upper part (1) of an assembled piston is disclosed, comprising a radially directed inner contact surface (2) arranged on the underside of an annular rib (15) and a radially directed outer contact surface (3) arranged on the underside of an annular wall (25), the outer (3) and the inner contact surface (2) each having a grooved profile in the form of concentric grooves with an average depth between Rz 10 and Rz 30. The wear on the contacting surfaces of the upper piece and the lower piece of the assembled piston is thus reduced.

    Abstract: A brake actuating device has an actuator functionally connected between a piston and a brake pedal lever. The actuator is capable of varying the path length of a force-conducting connection between the brake pedal lever and the piston of the brake cylinder via a displaceable element. A spring element acts on the brake pedal lever. The spring force varies during the variation of the path length such that a sum of the spring force and a force acting on the brake pedal lever from the brake cylinder remains essentially unchanged. The spring element is fastened with one end to the displaceable element and with the other end to the brake pedal lever with the interposition of a tensioning mechanism, which is guided by a cam track provided on the brake pedal lever. The cam track and the spring element are designed such that a displacement of the displaceable element into any possible position of the brake pedal lever does not generate a change in the pedal force at the brake pedal lever that is perceptible to the driver.

    Abstract translation: 制动器致动装置具有功能地连接在活塞和制动踏板杆之间的致动器。 致动器能够通过可移动元件改变制动踏板杆和制动缸的活塞之间的力传导连接的路径长度。 弹簧元件作用在制动踏板杆上。 弹簧力在路径长度的变化期间变化，使得弹簧力和作用在来自制动缸的制动踏板杆上的力的总和基本保持不变。 弹簧元件的一端固定在可移动元件上，另一端固定在制动踏板杆上，插入一个张紧机构，该张紧机构由设置在制动踏板杆上的凸轮轨道引导。 凸轮轨道和弹簧元件被设计成使得可移动元件在制动踏板杆的任何可能位置的位移不会产生驾驶员可感知到的制动踏板杆处的踏板力的变化。

    Abstract: A series of new bis(imino)pyridine vanadium(III) complexes was synthesized according to formula: They were tested for the homogeneous catalytic dimerization of propylene after activation with MAO and showed excellent selectivity for dimerization. The catalysts can be used with or without PPh3 as an additive to produce ≧80% dimerized alkenes.

    Abstract: A process is disclosed for removing heavy metals from a hydrocarbon gas stream by contacting the hydrocarbon gas stream, which contains a heavy metal and less than 10 ppm oxidizing compounds, with a composition containing a molecular sieve and sulfur resulting in a treated stream containing less heavy metal than the hydrocarbon gas stream; wherein the molecular sieve contains alumina, silica, and iron, and optionally copper and zinc. Optionally, the hydrocarbon gas stream can also contain a sulfur compound.
