Title: Actuator
Inventor: GRONOWSKI ARTUR
IPC: F16K31/04
Filed: 1985-11-02
Abstract: Actuators are used for opening and closing many different types of devices. Depending on the function of the said devices, either the opening or the closing movement must frequently take place all of a sudden. In the case of the actuator (1) according to the invention, an energy storage means (15) is mounted on the free end of an actuating spindle (11). A spring plate (16) is secured on the actuating spindle (11) at both ends of the energy storage means (15) by means of a retaining ring (17 and 23 respectively). Which spring plate actuates the energy storage means (15) is determined by the direction of rotation of the driving motor (5). The direction of rotation of the motor (5) is accordingly chosen according to which movement of the actuating member is to take place all of a sudden. It is therefore possible to use an actuator according to the invention for both functions without structural modifications. <IMAGE>

Title: Method for the controlled braking and positioning of bar stock
Inventor: WENZEL JUERGEN DIPL ING
IPC: B21B43/00
Filed: 1986-01-22
Abstract: The invention relates to a method for the controlled braking and positioning of installations or material with technologically required retardation. The method relates, in particular, to the controlled braking of rolled bars by means of brake drivers of rolled bars in the finishing region of rolling mills. The aim of the invention is to increase the yield of the mill train and also improve the alignment of the mill train and shorten the cooling bed. The object of the invention is to achieve a technologically adapted retardation to the bar speed and acceleration existing in each case and also the required braking distance, with a maximum available braking period. The object is achieved in that, by jolt limiting, the speed is converted into a constant braking phase and by continuously comparing the current bar speed and acceleration and also the braking distance still resulting with the fixed exit speed, exit acceleration and the available braking distance, the necessary retardation is determined and the change-over points for the jolt are defined.
