The upper impeller is arranged at a height above the mid-level of one of the compartments, and the upper impeller is an upward pumping axial or mixed flow impeller.

Abstract: A stirring impeller, an arrangement, and a use. The impeller comprises a hub disc comprising a shaft attachment structure arranged centrally in the hub for receiving a shaft centrally and perpendicularly from an upper side of the hub disc, a plurality of upper blades arranged on the upper side of the hub disc, and a plurality of lower blades arranged on a lower side of the hub disc. At least one of said plurality of upper blades is arranged to have jet angle of 5°-45°, and the lower blades have a jet angle that is different than said jet angle of least one of said plurality of upper blades.

Abstract: The invention discloses a computer executable method for a first computer system to amend a transaction with an invitation token to invite a user to use a service provided by a second computer system wherein the service is subscribed by the first system. The method is characterized in that it comprises steps for requesting by the first computer computer system the creation of the invitation token using information indicating a trust relationship between the first computer system and the second computer system, and amending by the first computer system the transaction with a URL comprising the created invitation token. The amended transaction is sent to the recipient system. A method for using the invitation token to invoke an application service is also disclosed.

Abstract: An approach is provided for providing a contextual model based upon user context data. A context modeling platform collects context data on offline activities of a user. The context modeling platform maps the collected user context data as context data points into a multidimensional contextual model. The context modeling platform causes, at least in part, actions that result in reception of at least one multidimensional contextual model of another user. The context modeling platform compares the multidimensional contextual model of the user with the multidimensional contextual model of the another user.

Abstract: An approach is provided for providing a contextual model based upon user context data. A context modeling platform collects context data of a user from a plurality of sources, and the sources include at least online activities of the user. The context modeling platform maps the collected user context data as context data points into a multidimensional contextual model.

Abstract: A method and system for controlling a pulverized coal fired boiler wherein the flow of a coal/air mixture flowing to each burner is monitored and transmitted to a distributed control system. The distributed control system also monitors and controls the position of dampers in a splitter that feeds the coal/air mixture to the burners. The dampers are controlled in a closed loop fashion to achieve a optimal boiler performance.

Abstract: An approach is provided for automatic geo-location and social group indexing thereby search geo-locations. A geo-location search learning platform receives a query specifying words, and retrieves context information of a user based upon a criterion. The geo-location search learning platform then assigns to the user a social group identifier identifying a social group based on the context information, retrieves one or more social group indexes based upon the social group identifier, retrieves one or more geo-location indexes based upon the one or more social group indexes, and generates a search result using, in response to the query, the one or more geo-location indexes and the words.

Abstract: An approach is provided for automatic geo-location search learning. A geo-location search learning platform receives a query specifying words, and initiates a point-of-interest search on the query, an address search on the query, and a partial search on some of the words. The geo-location search learning platform then combines results of the point-of-interest search, the address search, and the partial search, determines context information for a user; and sorts the combined results based on the context information thereby recommending the researched results to the user in a priority list as sorted.

Abstract: A method for manufacturing a cutting blade, which cutting blade is meant particularly to be used as a rotating cutter blade and, which is manufactured from a blade preform, being provided with a cutting surface. The blade preform includes a frame part, being made of a basic material and in which on an attachment surface, existing essentially at a cutting area of the cutting blade to be manufactured, is processed at least a wear resistant material layer that forms the cutting surface. The layer includes steel that is alloyed with tungsten or chromium and vanadium. A cutting blade, being manufactured according to the method, and use of an auxiliary material in manufacturing thereof.

Abstract: A method in connection with laser use, wherein one or more laser beams emitted by one or more laser sources are focused by beam guiding elements on a fusing spot. A filler delivered to the fusing spot is melted, especially for performing a welding, coating, and/or piece manufacturing process. The filler includes a substantially solid-state, elongated filler material that is fed by a delivery system to the fusing spot. The fusing spot is centrally located relative to the one or more laser beams focusing on the fusing spot. The one or more laser beams are diverged with a multi-segment mirror, especially for maintaining the symmetry of the intensity distribution thereof, whereby beams or divisional beams, reflecting from its various segment elements in substantially divergent directions, are converged on the fusing spot by a condenser system included in the beam guiding elements.

Abstract: A method for forwarding a call in a telecommunications network, where subscriber A's call is transferred using the call forwarding service from subscriber B's first terminal equipment to his/her second terminal equipment, the said second terminal equipment giving an indication of an incoming call. To provide a more user-friendly and less costly service for the user, the system monitors, when forwarding the call, whether the user performs a pre-defined action while the mobile telephone is ringing, and if such an action is detected, the call is re-routed back to the first terminal equipment. The method is particularly suitable for users who have both a fixed-wire telephone line and a mobile telephone.
