    摘要： The invention relates to a device, in particular for the treatment of low-viscosity polymer melts, containing a vessel (1) with a stirrer element, the stirrer element (6) essentially comprising a support structure which passes through the vessel and on which surface formers (8) are arranged. According to the invention, the support structure is designed as a cage-like rod frame (7).This results in the following advantages:1. Owing to the now possible continuous wetting or wiping of the surfaces, encrustations and inhomogeneities are avoided.2. Due to enhanced cascading with weir plates, the residence time spectrum can be controlled, which likewise improves the product quality.3. The flexing of the stirrer element is reduced.

    摘要： A polycondensation reactor for processing low viscosity polyester or another polymer into relatively highly viscosity polymer comprises a substantially cylindrical horizontal reactor vessel with a polymer inlet and a polymer outlet adjacent its opposite ends and a vapor exhaust opening in the upper side of the vessel at its outlet end. A polymer agitator is rotated axially within the chamber and includes plural alternating annular overflow and underflow baffles and multiple perforated film-forming screens disposed therebetween in parallel spaced relation to one another. The overflow baffles are in peripheral polymer-sealing relation to the vessel while the underflow baffles have multiple underflow recesses in their outer peripheries, whereby the baffles define a tortuous polymer flow path alternately through their respective polymer overflow and underflow openings to control residence time, distribution and viscosity growth as the polymer flows between the baffles. The baffles and screens are integrally fixed coaxially at their outer peripheries by axially extending wiper bars. Aligned openings in the baffles and screens along the rotational axis of the agitator provide for free flow of volatiles to the exhaust opening.

    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.
