Patent number: 7270719Abstract: The invention relates to the use of PVD technique for the application of a low static friction and wear resistant coating consisting essentially of titanium nitride or a diamond-like carbon—DLC, with or without an addition of tungsten carbide, on a stainless steel, in one and the same operation as the surface hardening of the stainless steel. In this way, in one single operation, a low static friction is obtained on a very hard and wear resistant surface. Moreover, the dimensions of the work-piece are maintained unaltered, which makes the invention very useful in the production of, e.g., cam followers, cylinder tubes and piston rods for shock absorbers. The used stainless steel has the following composition (in weight %): carbon max about 0.1; nitrogen max about 0.1; copper from about 0.5 to about 4; chromium from about 10 to about 14; molybdenum from about 0.5 to about 6; nickel from about 7 to about 11; cobalt 0 to about 9; tantalum max about 0.1; niobium max about 0.1; vanadium max 0.Type: GrantFiled: January 13, 2004Date of Patent: September 18, 2007Assignee: Sandvik Intellectual Property ABInventor: Göran Berglund

Patent number: 6726258Abstract: A vehicle is subjected to many requirements and wishes. One of these is that the vehicle is to protect passengers and load during a collision. This is achieved in that different parts in and on the vehicle are designed and constructed such that they, in different ways, absorb, distribute and channel energy during a collision. A bumper bar for a vehicle must be deformed both elastically and/or plastically during a collision. This invention offers a bumper bar that in its basic construction provides these properties. The invention concerns a bumper bar for vehicles where the bar is extended and has a closed cross-section with at least one forward flange (1) facing forwards in the normal direction of motion of the vehicle, an upper web (3) and a lower web (4). The forward flange (1) of the bumper bar is provided with elastically deformable grooves (6).Type: GrantFiled: July 22, 2002Date of Patent: April 27, 2004Assignee: Accra Teknik ABInventors: Anders Sundgren, Mats Lindberg, Göran Berglund

Patent number: 6185978Abstract: In a method of manufacturing a curved and quenched profile element, a profile element is positioned in a die tool with relatively movable tool halves for forming the profile element into a desired curved shape. The profile element is pushed between the tool halves thereby heating the profile element to a quenching temperature and forming it into the desired curved shape. Heat is dissipated from the curved profile element at an elevated cooling device whereat a cooling liquid flows through the die tool while the profile element is still contained therewithin. The profile element is transported in a forward direction along a manufacturing path to the cooling device and is transported in the same forward direction to remove it from the cooling device thereby providing continuous mechanical handling of the profile element during the manufacturing process.Type: GrantFiled: January 28, 1999Date of Patent: February 13, 2001Assignee: Accra Teknik ABInventors: Anders Sundgren, Mats Lindberg, Göran Berglund
