Patent number: 6692199Abstract: A cutting insert for grooving and parting as well as profiling and longitudinal turning of metallic work-pieces, includes a shaft part and at least one cutting head. There is a front end surface at the front end of the cutting insert, and a rear end surface at the rear end of the cutting insert. The shaft part includes a top side, a bottom side and side surfaces extending between the tope and bottom two sides. The cutting head carries a cutting edge defined by the intersection between a chip surface and a clearance surface. The cutting edge has a circular shape and has mainly a constant curvature between the ends thereof. The chip side of the cutting head is provided with a first chip-forming device placed immediately inside the cutting edge.Type: GrantFiled: January 30, 2003Date of Patent: February 17, 2004Assignee: Sandvik ABInventors: Claes Andersson, Håkan Fransson

Patent number: 6454459Abstract: A device for thermal analysis of molten metals comprising two thermocouples is described. It comprises a mould (1) with a spherical cavity (2), the one thermocouple (3) being placed such that it extends over the central portion of the cavity (2), a cylindrical duct (5) which communicates with the cavity (2) and a cylindrical part (7) which communicates with the lower portion of the cavity (2), the other thermocouple (6) being placed in the transition between the cavity (2) and the cylindrical part (7). A process for thermal analysis of molten metals with the aid of the device is also described. The difference in temperature (11) in the temperature/time curve for the thermocouple which is centrally placed and the lower themocouple which is peripherally placed when the solidus temperature determined by means of the centrally placed thermocouple (3) has been reached is used as a measure of the thermal conductivity.Type: GrantFiled: August 25, 2000Date of Patent: September 24, 2002Assignee: Novacast ABInventors: Rudolf Valentin Sillén, Kjell Pettersson, Häkan Fransson

Patent number: 6236986Abstract: The present invention relates to a method and a device for extracting information from a database, which comprises a plurality of data records, each data record comprising at least two data elements, each data element being defined by a data element type and a data element value. First, the data records are read into the primary memory of a computer, so that all processing of the data may be done off-line. Then, the data element values are binary-coded and stored in one or more tables. When the selection of at least one data element value is detected, all binary-coded data element values are examined to obtain all data records implied by selection. Due to the binary-coding, these data records are found very quickly. Finally the data element values implied by the selection is kept track of in a status set.Type: GrantFiled: May 21, 1997Date of Patent: May 22, 2001Assignee: Qliktech International ABInventors: Staffan Gestrelius, Håkan Fransson, Björn Berg

Patent number: 5299540Abstract: A respective fuel injector is provided for each cylinder in a multiple cylinder internal combustion engine. Each fuel injector is located in a respective cylinder head. There are a plurality of fuel passages for each cylinder head. Each fuel passage into the cylinder head is in two sections. One section extends from the space for receiving the fuel injector diagonally with respect to the longitudinal direction of the engine and opens on the transverse surface of the cylinder head and is sealed there. Another passage section extends at an angle to the first passage section and then intersects the lateral side surface of the cylinder head. The two passage sections each comprise a bore in the cylinder head. A wall inside the cylinder head extends between and separates two spaces for receiving inlet valves to the injector and two spaces for receiving exhaust valves from the injector. That wall extends on one side along an air intake port into the cylinder head.Type: GrantFiled: February 22, 1993Date of Patent: April 5, 1994Assignee: Saab Scania AktiebolagInventors: Hakan Fransson, Peter Sperle

Patent number: 5297524Abstract: A respective fuel injector for each cylinder in a multiple cylinder internal combustion engine. The fuel injectors being supplied with fuel via passages in the cylinder heads of the engine. The passages all open on one side of the engine. On the one side of the engine there is a longitudinal fuel molding with longitudinal channels passing through the molding and ports from each channel communicating with the respective passages in the cylinder heads. The molding is secured to the cylinder heads of the engine. The fuel molding allows simple pipe laying and a protected position for the pipes, and it also reduces the risk of leakage.Type: GrantFiled: February 22, 1993Date of Patent: March 29, 1994Assignee: Saab-Scania AktiebolagInventors: Hakan Fransson, Peter Sperle
