Patent number: 10508580Abstract: The present invention relates to a combined heat exchanger and exhaust silencer for a vehicle, comprising a bypass valve configured to: in a first state, allow a flow path for exhaust gas to be open from an inlet to an outlet via an at least partly perforated bypass pipe, and in a second state, close said flow path, whereby at least a main portion of said exhaust gas is forced through a second flow channel comprising a heat exchanger pipe. The second flow channel is formed by an annular space between an at least partly perforated second pipe and an at least partly perforated third pipe. A sound absorbing material surrounds the bypass pipe and the third pipe, and is further arranged inside the second pipe.Type: GrantFiled: May 1, 2017Date of Patent: December 17, 2019Assignee: Volvo Car CorporationInventors: Fredrik Ekstrom, Hans Erik Olsen, Mattias Svensson

Patent number: 9175438Abstract: The method is for separation of lignin from original black liquor (BLIN) and has the following phases in sequence. A first precipitation phase (PR1) for precipitation of lignin by a first acidification of the original black liquor by adding a first acid or mixture of acids (G1a) followed by a first storage phase wherein precipitated lignin particles are allowed to increase in size, followed by a second precipitation phase (PR2) for precipitation of lignin by a further acidification of the original black liquor by adding a second acid or mixture of acids (G1b). By retaining the acidified black liquor for at least 25 minutes in the storage phase are the precipitated lignin particles allowed to grow in size and the filterability is improved considerably.Type: GrantFiled: November 11, 2011Date of Patent: November 3, 2015Assignee: Valmet ABInventors: Martin Wimby, Mattias Svensson, Henrik Wallmo, Fredrik Öhman, Per Tomani, Lars-Erik Åkerlund

Patent number: 7871551Abstract: Systems, apparatus, and methods feed and distribute a powder over a working area used for producing three-dimensional objects. A powder storage unit contains a supply of powder, and a distribution member is arranged to be moveable across the working area to distribute a portion of powder onto the working area. In an embodiment, the distribution member is, in a first step, moveable a predetermined distance into a supply of powder placed in the powder storage unit, said distance being sufficiently long to bring about a transfer of a portion of powder from the powder supply at one side of the distribution member to another side of the distribution member facing the working area, and the distribution member is, in a second step, moveable towards and across the working area to distribute the portion of powder onto the working area. Other embodiments are disclosed.Type: GrantFiled: May 11, 2005Date of Patent: January 18, 2011Assignee: Arcam ABInventors: Göran Wallgren, Ulf Ackelid, Mattias Svensson

Patent number: 7371344Abstract: A blank for a rotary tool for chip removing machining, such as a helix drill or an end mill is formed by advancing a mixture of hard metal powder and carrier through an extrusion passage. The mixture is fed past a core having pins secured thereto for forming respective internal holes through the mixture. Then the mixture is advanced through a rotary part that is rotating about a center axis of the extrusion passage, wherein the rotary part and the internal holes become twisted to a predetermined pitch. The mixture is also advanced past a plurality of shaping parts which project transversely into the extrusion passage for shaping exterior chip flutes in the mixture, e.g., by embossing or cutting. The mixture is allowed to harden into a green body, and the green body is then sintered to form a blank.Type: GrantFiled: June 1, 2004Date of Patent: May 13, 2008Assignee: Seco Tools ABInventors: Mikael Grönquist, Johnny Bruhn, Mattias Svensson

Patent number: 7311479Abstract: The present invention relates to a tool as well as a blank for manufacturing of the tool. The tool is made of solid cemented carbide and includes a shank for mounting in a rotatable spindle and chip flutes. Lines of intersection between the chip flutes and clearance surfaces form cutting edges at a cutting end of the tool. The flush channels extend through the entire tool in order to transfer flushing medium to the cutting end of the tool. The flush channels have varying pitch.Type: GrantFiled: December 5, 2005Date of Patent: December 25, 2007Assignee: Seco Tools ABInventors: Johnny Bruhn, Mattias Puide, Mattias Svensson, Anders Björk, Jimmy Karlsson, Mikael Grönqvist
