Abstract: A rotor of a gas dispersion arrangement, including a cover disc, air slots arranged to protrude away from the cover disc, the air slots defining an interior space in the interior of the rotor, an air channel connected to the air slot for supplying air to be dispensed in slurry, and slurry slots arranged between and an alternating way with the air slots around the interior space. The slurry slots are in fluid communication with the interior space, and radially extending blades are arranged for separating the air slot from adjacent slurry slots. The cover disc includes at least one through-hole extending from an upper surface of the cover disc to at least one of the slurry slots.

Abstract: A reel-up for reeling of a fiber web (W) around a reel spool (15B) to form a parent roll (20B; 20A) by use of a reeling nip (N) between a reeling cylinder (10) of the reel-up and the parent roll (20B) under reeling, has a primary reeling position and a secondary reeling position. The reel-up (10) has the reeling cylinder (10), substantially horizontal guides (14) and for each end of the reel spool (15A; 15B), loading arms (12,13; 16,17) and carriages (18) and the primary reeling position is fixed.

Abstract: The object of the invention is an arrangement and a guide rail bracket for fixing the compensating weight guide rails of an elevator.

Abstract: Methods and arrangements are provided for handling, within a communications system comprising a distributed domain (301) and a central domain (303), electronic records that contain predictions of the outcome of a certain incident. Within the distributed domain (301) there is generated (304), before the outcome of the incident is known, a multitude of electronic records that contain predictions of the outcome of the incident. The electronic records are conveyed (305) from the distributed domain (301) to the central domain (303). After the outcome of the incident is known, the central domain (303) finds out (306) which of the electronic records, if any, contain correct predictions of the outcome of the incident. Each of the electronic records is furnished (304, 401, 502, 902, 1202, 1911), within the distributed domain (301), with a cryptographically protected proof of a certain moment of time associated with the generation of the electronic record.

Abstract: A method for adapting a bus to data traffic in a system comprising several functional units (311, 312, . . . , 31n) and a bus structure. The functional units are divided into at least two sets so that units, which mainly transfer data with each other belong to a same set and are interfaced with the same separate sub-bus (321; 322). The sub-buses can be united by switches (SW) into a more extensive bus, which is only used when data must be transferred between different sets. Supply voltage of each sub-bus is adjustable and is set the lower the less traffic there is on the bus. The parallel transfer operation makes it possible to increase the transfer capacity of the bus structure without increasing it's clock frequency. Furthermore energy consumption can be reduced by dropping the supply voltage of the bus circuits so that the bus retains the transfer capacity needed.
