Abstract: A method and arrangement for removing CO2 from smoke or exhaust gas of a combustion process in a power plant are provided. The exhaust gases comprising CO2 are fed into a tank in which cellular organisms, such as micro algae, are present, converting the CO2 into biomass when nutrients are added. The micro algae and/or the generated biomass have magnetic particles added, which combines with the algae and/or the biomass.

Abstract: Apparatus for forming an extended nip between a mating roll and a shoe roll for treating a product web, the shoe roll having a stationary carrier and a flexible roll shell which can rotate around the carrier and which, in the region of the extended nip, is supported on a hydrodynamically lubricated running surface of a press shoe guided on the carrier, for which purpose a device for applying lubricant to the inner side of the roll shell is provided, where, in an inlet region, the press shoe has a plurality of holes which are arranged transversely with respect to the machine running direction, are connected to a lubricant supply in order to be fed with lubricant and, for this purpose, end at the running surface, and the holes comprise restrictors whose resistance is designed for a pressure drop of 5 to 15 bar.

Abstract: The invention relates to a roll for pressure treatment of material bands comprising a carrier (3), a roll sleeve (4) arranged on said carrier (3), and at least one pressure chamber (12) which is disposed between the carrier (3) and the roll sleeve (4), is at least partially filled with liquid and can transmit at least indirectly a hydraulic pressure force from carrier (3) to the roll sleeve (4). According to said invention, the pressure chamber(s) is provided with an elastic element (18?) which unrestrictedly communicates with supporting liquid and is compressible when a liquid pressure required for producing a supporting hydraulic force is exceeded.

Abstract: The invention relates to an extended-nip roll press for dewatering a fibrous web in a press nip which, on one side, is formed by a rotating mating roll and, on the other side, is formed by an extended-nip press roll, whose roll centers lie in a stack plane, and the extended-nip press roll has a stationary support and a flexible roll cover that can rotate about the support, the cover in the region of the press nip being supported on the support on a sliding surface which is formed on an upper part, defining an entry and exit, of a press shoe that can be displaced with respect to the support in a loading direction, it being possible for the press shoe to be displaced radially along a loading plane which intersects the stack plane at the center of the mating roll and at an acute angle to the exit direction.

Abstract: A device for treating a continuously advancing material web with ultrasound includes an ultrasound generator and a sonotrode, rigidly connected with the former in a manner so as to transmit ultrasound. The sonotrode has a face which lies opposite a counter-tool. The material web is passed through the gap. The module composed of the ultrasound generator and the sonotrode is connected with the machine frame via a piezoelectric actuator, by means of which small displacements of the face of the sonotrode relative to the circumference surface of the counter-roller can be balanced out.

Abstract: A heatable roller which can be heated from inside the roller body by a heating device. Provided radially outside the heating device are axially parallel bore holes uniformly distributed over the periphery of the roller body which are connected at the ends by annular chambers. The bore holes and the annular chambers form a closed system which is partially filled with water. This system operates to make the temperature uniform via condensation heating in the event of local temperature reduction.

Abstract: The roller is provided for pressure treatment of a strip of paper, textile, plastic film, sheet metal or similar material. It includes a hollow roller made of a fiber-reinforced synthetic resin material, and a cross-beam which passes through the hollow roller lengthwise. The cross-beam is mounted at its ends, in external supports, so as not to rotate. Hydrostatic support elements are arranged on the cross-beam on the side on which pressure is exerted. The elements can be pressed against the inside circumference of the hollow roller by means of a hydraulic fluid. The support elements have a length not exceeding 20 cm in the longitudinal direction of the hollow roller, follow each other closely in the longitudinal direction of the cross-beam, and can all be controlled independently of one another.
