    摘要： The present invention relates to a new, particularly economical process for preparing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a superheated gas mixture, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The superheated gas mixture, with which the feed composition is contacted, is selected from: (i) a superheated gaseous mixture of steam and an inert gas; and (ii) a superheated gas mixture of steam and air. The superheated gas mixture has a steam content of 40 wt. % to 99 wt. %, based on the total weight of the superheated gas mixture.

    摘要： The invention relates to an open-loop control process for the motional guidance of conveyed material (32) in a conveying device (30) and to a corresponding conveying device (30). The conveying device (30) has a movable means (36) for realizing the conveyance and a first motion detector (42) for measuring a first actual position value (x1act) for the movable means (36) and a second motion detector (40) for measuring a second actual position value (x2act) for the conveyed material (32). The control is herein realized with a position control having a position control clock (Tpc) and with a speed control (GR) having a relatively faster speed control clock (Tsc), in which, in the position control clock (Tpc), desired position values (xcmd) are preset as the command variable and, in the speed control clock (Tsc), registered first actual position values (x1act) are fed back to the position control, in which the position control is provided, at least in part, in an open-loop control part (NC) and the speed control (GR) is provided in a drive part (A), and in which a control variable (R) is fed back into the position control, which control variable is dependent on second actual position values (x2act) registered in the position control clock (Tpc). A high accuracy and dynamic can thereby be obtained.

    摘要： A transmission gear wheel has at least two gear wheel elements which are provided with teeth on their circumference and which, coaxially and non-displaceably with respect to one another in the circumferential direction. Mutually offset teeth connect the elements with one another such that, for the engagement of a meshing gear wheel, the existing tooth flank play is reduced or discontinued. At least the teeth of one gear wheel element are constructed such with respect to their elasticity that, during the engagement of meshing gear wheel, at least starting at a defined transmitted torque, the offset in the circumferential direction of the tooth transmitting this torque is at least partially discontinued with respect to the tooth of the other gear wheel element by means of a deformation.
