Abstract: The invention relates to sealing systems and methods for the operation of sealing systems of suction rolls, comprising inside at least one suction box (4) which is sealed laterally by one sealing strip system (1, 2) respectively from the roll shell (3) and each sealing strip system (1, 2) comprises one sealing strip (1.1, 2.1).

Abstract: The invention relates to sealing systems of suction rolls, comprising inside at least one suction box (4) which is sealed laterally by one sealing strip system (1, 2) respectively from the roll shell (3)and each sealing strip system (1, 2) comprises one sealing strip (1.1, 2.1), which is inserted in a sealing strip holder (1.2, 2.2), whereby at least one lubricant supply is integrated in at least one sealing strip holder (1.2, 2.2), whereby at least one opening (10) of the lubricant supply runs at an outer side of the sealing strip holder (1.2, 2.2) in the sealing strip holder (1.2, 2.2), which is located in front of the sealing strip (1.1, 2.1) in the direction of movement of the roll shell (3).

Abstract: Sealing device for sealing at least one zone of underpressure or overpressure adjoining a moving surface that includes at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction. The sealing device includes a sealing section located at the front and a ventilation section located at the rear. The sealing section is structured to sealingly interact with the moving surface; and the ventilation section is structured and arranged to form a gap with the moving surface that widens in the surface running direction.

The sealing section is structured to sealingly interact with the moving surface and the ventilation section is structured to contact the moving surface and includes a run off surface having at least one of a substantially sawtooth and wavy shape surface arranged at an end of the rear.

Abstract: The invention relates to a reproducible standard for calibrating and checking the bright-field channel of a surface inspection device used for examining the flat surface of a sample and to a method for producing said standard whereby a microstructure is produced on a surface of a substrate provided as a standard, characterized in that the microstructure is smoothed out.

Abstract: An anchoring arrangement for use in underground mining or foundation work or as a reinforcing element for concrete includes a rod-shaped tension member of composite fiber material which has, over at least an anchoring portion thereof, a helically extending external thread with ribs formed by impressing valleys in the tension member. An anchoring member having a corresponding internal thread can be screwed onto the tension member. For obtaining a radial pressure on the tension member as a result of a wedge effect, the angle of inclination of the sides of the thread relative to the longitudinal axis of the tension member is smaller than 45.degree.. The thread preferably is a fiat trapezoidal thread. In an anchoring member which is stiff relative to circumferential tensile forces, the flat angle of inclination of the sides of the thread increases the radial pressure acting on the tension member, which leads to an increased effect into the depth and a higher resistance to shearing.
