Patent number: 7278837Abstract: The invention relates to a damper device for a piston pump. The device includes a partly air-filled, upright tube placed on the inlet conduit of the piston pump, and a partly air-filled, upright tube placed on the outlet conduit of the piston pump. The two upright tubes are interconnected with each other by means of a tube on which a shut-off valve is disposed. Each of the upright tubes is connected to a blower valve, respectively. Both of the blower valves are connected to a common compressed air source. The damper device may be adapted in a simple manner for aseptic operation and/or elevated product pressure.Type: GrantFiled: February 11, 2002Date of Patent: October 9, 2007Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Rolf Malmberg, Torsten Olsson, Lars-Göran Persson

Patent number: 5473649Abstract: A fuel assembly for a light-water nuclear reactor includes a plurality of vertical fuel rods (10) which are arranged, in spaced relationship in the lateral direction, between a bottom tie plate (11) and a top tie plate (12). The bottom tie plate and the top tie plate are provided with through-holes (35) for inlet and outlet of coolant for the fuel rods. Below the bottom tie plate, in the flow path of the water, a debris catcher (36) is arranged which includes helical springs (40) that are arranged in a frame having at least two ends (37, 38) in the form of substantially parallel plates, the flat sides of which are interconnected via pins (39). The pins are arranged in spaced relationship in at least two rows between the ends in such a way that the springs, in spaced relationship or adjacent to each other, can be fixed between the rows of pins in one or more layers.Type: GrantFiled: May 12, 1993Date of Patent: December 5, 1995Assignee: ABB Atom ABInventors: Torsten Olsson, Anders Soderlund

Patent number: 5363422Abstract: Spacers (10) with a cell-formed lattice-work for retaining parallel elongated elements such as fuel rods (5) into a bundle in a nuclear reactor fuel assembly are arranged in a suitable spaced relationship to each other along the bundle, and the cells are formed from tubular sleeves (1). Each one of these sleeves (1) offers a passage for one of the elements in order to fix the elements in relation to each other. Substantially half the number of sleeves (1) in a spacer (10), distributed evenly over the cross section of the bundle, are located in a first plane across the bundle and are joined to each other inside a first frame (11) surrounding the bundle, thereby forming a lattice of sleeves (1) and gaps (13). The remaining sleeves (1) of the spacer (10) are joined together inside a second frame (12) surrounding the bundle and are located in a second plane, separate from the first plane, across the bundle.Type: GrantFiled: April 20, 1992Date of Patent: November 8, 1994Assignee: ABB Atom ABInventors: Olov Nylund, Ragnar Mansson, Torsten Olsson, Tibor Farkas, Thorbjorn Sahlin
