Abstract: The invention relates to an arrangement for obtaining a fiber suspension for producing a web of paper, cardboard, tissue, or other fibers from at least one high-consistency flow containing fibrous material and filling material in the approach flow system of a fiber web manufacturing machine, at least one high-consistency flow being directed through at least one screening device. In order to reduce the screening effort, the accept from the screening device is directed to the headbox of the machine, and the reject from the screening device is redirected upstream into a high-consistency flow.

Abstract: The invention relates to an adjusting device which is provided for pivoting a pivotal element of a piece of furniture in relation to a fixed element of the same, said furniture being used in households, work areas and in health care fields. The inventive device comprises a retaining arm (16), an actuating drive (24) held on said retaining arm (16), and an actuating arm (26), whereby the retaining arm (16) and the actuating arm (26) can be moved in relation to one another by the actuating drive (24). The adjusting device (10) is held on the fixed element (18) via a free end of the retaining arm (16) and is held on the pivotal element (12) via a free end of the actuating arm (26). The actuating arm (26) is pivotally connected, via the end thereof situated opposite the free end, to the retaining arm (16).

Abstract: An adjusting device for a piece of furniture on which to lie or for sitting on with at least one swivel part (12, 14) that is pivotally attached, by way of a torsion bar (20, 22), to the piece of furniture on which to lie or for sitting on, with a housing (26) and with a bearing element (38, 40) accommodated in the housing (26) whereas the bearing element (38, 40) is provided with a recess (66, 68) that partially surrounds the torsion bar (20, 22) and in which the torsion bar (20, 22) may be introduced so that the adjusting device (24) is attached to the torsion bar (20, 22) with positive fit, and with an actuating drive (46, 48) that is accommodated in the housing (26) and acts on the torsion bar (20, 22). The bearing element is connected to the actuating drive (46, 48) which are slidably arranged in the housing (26).

Abstract: The subject matter of the invention is an adjusting device for a piece of furniture on which to lie or for sitting on with at least one swivel part (12, 14) that is pivotally attached, by way of a torsion bar (20, 22), to said piece of furniture on which to lie or for sitting on, with a housing (26) and with a bearing element (38, 40) accommodated in said housing (26), wherein the bearing element (38, 40) is provided with a recess (66, 68) that partially surrounds the torsion bar (20,22) and in which said torsion bar (20, 22) may be introduced so that the adjusting device (24) is attached to the torsion bar (20, 22) with positive fit, and with an actuating drive (46, 48) that is accommodated in the housing (26) and acts on the torsion bar (20, 22). The provision of an adjusting device that is easy to install on the piece of furniture and that can be manufactured at low cost is achieved by the fact that the actuating drive (46, 48) pushes the torsion bar (20, 22) into the recess (66, 68).

Abstract: The present invention relates to a puncture seal for sealing a blood vessel having a puncture opening in a body of a human being or an animal. The seal comprises a pressure chamber which can be attached to the body in the area of the puncture opening and subjected to an overpressure, wherein the pressure chamber has a supporting wall in an area opposite to the body. In order to create a puncture seal, in which the pressure chamber can be reliably sealed once the hypodermic needle has been removed, a sealing element made of a material with a certain elastic return force, which is at least 1 mm thick is provided and placed in the area of the support wall to be punctured by the hypodermic needle.

Abstract: The puncture closure for closing a blood vessel with a puncture, in particular an artery, a vein short circuited with an artery, a shunt or a prosthesis, etc. has a pressure chamber in which an overpressure may be created, provided with an opening for receiving a pressure medium and fastenable to the body in the area of the puncture. The part of the pressure chamber that faces the body is extensible. In order to create a puncture closure that reliably closes the puncture of a blood vessel without too much blood loss, without forming significant hematomas nor completely collapsing the blood vessel, the opening for receiving the pressure medium is located above a piercing channel of the puncture hole and the blood that flows out of the blood vessel is used as a pressure medium.

Abstract: The device (1) is used for aligning the strings of the netting, and particularly the netting of a tennis racket. In order to align the strings of the netting in a simple, accurate, quick and effortless manner, without damaging the strings, the aligning device has semi-ellipsoidal, semi-circular or oval platelets that act on the strings at their crossing points.
