    摘要: 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.

    摘要: 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.

    摘要: 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.
