Abstract: An approach is provided for determining that a user has been authenticated for an access to at least one service using a federated identity (401). The approach also comprises determining federated account information associated with the user based, at least in part, on one or more user accounts associated with the federated identity, the at least one service, the at least one or more other services, or a combination thereof (403). The approach further comprises determining one or more functions of the at least one service, the at least one or more other services, or a combination thereof to make available to the user based, at least in part, on the federated account information (411).

Abstract: A device for cutting wood or other materials comprises a saw blade clamping device for radially and/or axially fixing circular saw blades mounted axially displaceable on a drive shaft. Support bodies are provided axially displaceable on the drive shaft for each circular saw blade. The axial displacement of the circular saw blades takes place by guide spindles running parallel to the axis of the drive shaft and passing through the support bodies. At least one clamping element is mounted in the drive shaft 1, 20. The clamping element is mounted radially displaceable. In a first stage, the circular saw blades which are mounted on the support bodies are thereby displaced. In a second stage, the circular saw blades or support bodies are connected to the drive shaft in keyed and/or force locking engagement. Through the device, a displacement of the cutting width is possible without the time and labor intensive dismantling of the saw blades.

Abstract: In addition to ash and coke, the gasification residue contains alkaline earth metal sulfide and alkaline earth metal oxide because desulfuring agents have been supplied to the gasifier. At temperatures from 5.degree. to 80.degree. C. the gasification residue is mixed with an acid-containing aqueous solution so that a gas which is rich in H.sub.2 S is produced. Ash, coke, and alkaline earth metal salt are supplied to a flotation zone, in which coke is separated. A solid residue which contains ash and alkaline earth metal salt is withdrawn from the flotation zone. Carbonic acid or dilute sulfuric acid is preferably used as an acid.

Abstract: Fine-grained fuels are gasified in a fluidized state with a mixture of gasifying agents which comprise oxygen, water vapor and/or carbon dioxide. NH.sub.3 is substantially entirely removed from the product gas from the gasifier. All or part of the NH.sub.3 is combusted and any remaining NH.sub.3 is added to the exhaust gas from the combustor. In a preferred embodiment the content of nitrogen oxides and/or NH.sub.3 in the exhaust gas from the combustor and NH.sub.3 is supplied to the combustor at such a controlled rate that the contents of nitrogen oxides and NH.sub.3 in the exhaust gas to which NH.sub.3 has been admixed are minimized.

Abstract: Fuels are gasified in a fluidized state by a treatment with oxygen-containing gas and water vapor in a gasifying reactor. A solids mixture which contains ash and fine-grained fuels is combusted in a heating-up phase, which precedes the gasification and in which the temperature in the reactor is increased approximately to the temperature desired for the gasification. In a succeeding inertizing phase the supply rate of oxygen-containing gas is decreased and an inert gas is fed to the reactor until the product gas no longer contains free oxygen whereas the temperature is maintained virtually constant. In the succeeding gasification the fuel supply rate is increased and, after an adjusting time, the temperature is maintained virtually constant at the value desired for the gasification in the range from 600.degree. to 1500.degree. C. The gasification temperature is controlled by a change of the fuel supply rate.

Abstract: In a rotary-grate gas producer operated under a pressure from 10 to 100 bars, the fuel constitutes a fixed bed, which slow descends. The mixture of gasifying agents contains water vapor and oxygen is supplied to the fixed bed through a rotary grate and through an ash layer, which is disposed on the rotary grate. In order to ensure that the ash will have a particle size in a desired range, a first pressure (p1) is measured below the rotary grate and a second pressure (p2) is measured approximately at the top of the ash layer. The pressure difference (p1-p2) is compared with a setpoint, which is associated with the current ratio of water vapor to oxygen in the mixture of gasifying agent. Said ratio is increased when the pressure difference is insufficient and the ratio is decreased if the pressure difference is excessive.

Abstract: The lock container is connected to a reactor, which serves to gasify or to combust solid fuels. The lock container serves to remove ash from the reactor. A pressure of at least 2 bars prevails in the reactor. The lock container is pressurized and pressure-relieved in alternation. The pressure relief line communicates with a filter element, which is permeable to gas and substantially impermeable to solids and is disposed within the lock container. When the lock container is filled to the usual level during a pressure relief, at least one half of the filter element is surrounded by ash. The filter element may be tubular.
