摘要： The invention relates to a torsional vibration damper comprising a primary part (1) and a secondary part (2) which can be rotated relative to each other in a circumferential direction (3) against the force of at least one spring element. The spring element is designed as a pressure spring (4) which has two spring contact surfaces (5, 6) that face away from each other in the circumferential direction (3). The primary part (1) has a primary part contact surface (7) which faces the first spring contact surface (5) in the circumferential direction (3), and the secondary part (2) has a secondary part contact surface (8) which faces the second spring contact surface (6) in the circumferential direction (3). When a force is not being applied, a spacing (9) is formed between the first spring contact surface (5) and the primary part contact surface (7) and/or a spacing (10) is formed between the second spring contact surface (6) and the secondary part contact surface (8) so as to taper over the surfaces in a stepped manner or in a constant manner.

摘要： Device (1) for producing a fibrous web (FB), having: a first forming unit (10) with an endlessly circulating first fabric belt (12) and a first headbox (17) which is set up to apply suspended fibrous material for forming a first layer (L1) of the fibrous web onto the first fabric belt, and a second forming unit (25) with a second fabric belt (27) which is set up for endless circulation and a second headbox (32) which is set up to apply suspended fibrous material for forming a second layer (L2) of the fibrous web onto the second fabric belt, wherein the second forming unit is arranged above the first forming unit, with the result that the second fabric belt is guided along on the first fabric belt, in order to couch the second layer onto the first layer of the fibrous web at a couching point (30), and the first and the second forming unit are set up for forming the layers in such a way that one of the layers forms at least two plies and the other forms at least one ply of the fibrous web. According to the invention, at least one of the headboxes is configured as a multilayer headbox, with the result that at least two fibrous stock suspension plies which lie on one another can therefore be discharged at the same time for application on the fabric belt side in order to from an at least two-ply layer.

摘要： The invention relates to a hydraulic control device for a quick-acting valve of a steam turbine, comprising a module for reducing a hydraulic pressure by quickly opening an outlet valve and/or by unloading or loading an actuator for actuating the quick-acting valve, wherein a control valve assembly having at least three safety valves is provided in an operating-medium supply and/or control system, which safety valves are hydraulically connected in such a way that the safety valves do not open the outlet valve or unload or load the actuator until a safety circuit has been transferred to a quick-closure setting by at least two safety valves of the control valve assembly. According to the invention, an upstream valve (1.4) is hydraulically connected upstream of each safety valve (1.5) - said upstream valve being independent of the other safety valves (1.5) - in such a way that a safety valve (1.5) connected downstream of an upstream valve (1.4) can be hydraulically decoupled from the upstream valve during operation.
