Publication number: 20080126230Abstract: A method of processing service related accounting requests at an Online Charging System of an IP Multimedia Subsystem. The method comprises receiving a service related accounting request from an IP Multimedia Subsystem Serving Element, the request containing an identification of the chargeable events measuring methods supported by the Serving Element. A charging model appropriate to the chosen service is then selected, and one or more of the supported measuring methods are selected on the basis of the selected charging model. An amount of granted service units for the or each selected measuring method are determined and an accounting response, containing the amount(s) of granted service units and an identification of the corresponding measuring method(s), sent to the Serving Element.Type: ApplicationFiled: June 8, 2004Publication date: May 29, 2008Inventors: Mauro Bellora, Chiara Dotti, Leena Marjatta Mattila, Rolf Nilsson

Publication number: 20040083899Abstract: The invention relates to a method and an apparatus for mixing two phases (2, 3) of a food product (1), where the first phase (2) constitutes the largest fraction of the product (1) and the second phase (3) constitutes the smallest fraction of the product (1). The second phase (3) is caused to pass a first distributor device (4) which is provided with a large number of holes (5). The second phase (3) is distributed out in the first phase (2) which surrounds the first distributor device (4) and which is enclosed in a first distributor housing (8). The first distributor housing (8) has an inlet (9) for the first phase (2), as well as an outlet (10) for the united phases (2, 3). The united phases (2, 3) are thereafter caused to pass at least a further second distributor device (13) which is provided with a large number of holes (14). A second distributor housing (16) surrounds the second distributor device (13).Type: ApplicationFiled: December 23, 2003Publication date: May 6, 2004Inventor: Rolf Nilsson

Patent number: 5674402Abstract: A method for the treatment of sludge obtained from such a water treatment process wherein an aluminium or iron chemical is used as a coagulant, so as to reduce the amount of sludge, which method comprises the steps of:a) treating the water treatment sludge with an inorganic acid to produce an acidic sludge comprising dissolved aluminium or iron,b) optionally separating insoluble material from the acidic sludge to produce an acidic solution comprising dissolved aluminium or iron,c) treating said acidic sludge or said acidic solution with a +1-cation compound in the presence of sulphate ions in such conditions that the pH of the sludge or solution remains at a level where aluminium precipitates as an alunite compound or iron precipitates as a jarosite compound, andd) separating the precipitated alunite or jarosite compound from the remaining sludge.Type: GrantFiled: May 17, 1996Date of Patent: October 7, 1997Assignee: Kemira Kemi AbInventors: Rolf Nilsson, Simo Jokinen

Patent number: 4618153Abstract: An annular wiper for piston rods, disposed in a cylindrical wall opening wherein an axially movable piston rod is running, comprises a reinforced ring of an elastic, somewhat flexible material having a portion with an inner diameter slightly greater than the outer diameter of the piston rod and an axially outwardly projecting and radially inwardly projecting lip with a somewhat smaller inner diameter than the outer diameter of the piston rod. The reinforcement comprises a first annular portion surrounding the periphery of the elastic ring, creating a torque center line for the resilient ring, and a second annular portion absorbing as a compressive force the radially inwardly directed force exerted by the elastic ring as it turns around the torque center line.Type: GrantFiled: November 26, 1984Date of Patent: October 21, 1986Assignee: Volvo BM ABInventor: Rolf Nilsson

Patent number: 4543808Abstract: A mechanism to be utilized for winding wire on a spool in tight coils without space between them. The mechanism includes rotating devices (14) and (16) which when activated rotate the spool (12) about its longitudinal axis (13). A wire guiding unit is arranged to be automatically moveable in all directions to the side of the thus rotating spool. The unit comprises a pressure roller (2) or equivalent which with a predetermined force presses that section of wire which during winding runs inwards at an angle against that section of wire which comprises the previous coil of wire in the layer being wound. During winding the pressure roller (2) adjoins and presses the section of wire being wound against the last wound coil of wire and the mantle surface of the spool or the already wound underlying layer of wire.Type: GrantFiled: January 20, 1984Date of Patent: October 1, 1985Assignee: AB BoforsInventors: Rolf Nilsson, Hakan Bjornfoth, Knut Slungaard, deceased

Patent number: 4477101Abstract: Arrangement for coupling an implement to a hydraulically operated coupling device on a tractor, said arrangement comprising a male coupling frame attached to the tractor and cooperating with a female coupling frame attached to the implement, the arrangement in coupled position providing a power transmitting union. Power transmission is effected via an upper union where the coupling beams of the female frame straddle the corresponding guide beams of the male frame, and by two lower coupling devices consisting of catch hooks on the male frame and interacting coupling hooks on the female frame. The coupling members are locked and released by a separate spring-loaded latch provided with an indicating lever to which an operating mechanism has been attached.Type: GrantFiled: April 13, 1982Date of Patent: October 16, 1984Assignee: Tunamatic HandelsbolagInventors: Rolf Nilsson, Nils-Georg Lindstrom
