Patent number: 10807222Abstract: A dismounting tool for disengaging ball joint connections on suspension and steering assemblies is disclosed. The dismounting tool comprises an actuator having two receiving portions, where the actuator is operable to force two receiving portions towards each other along an actuation axis. The dismounting tool further comprises a first tool member having an anvil portion with an engaging surface and a second tool member having a bifurcated portion with a supporting surface. Each of the tool members comprises a through hole and are detachably mounted to a respective receiving portion such that the through holes are arranged coaxially about the actuation axis such that the engaging surface faces the supporting surface. The actuator is, upon actuation, configured to move the two tool members towards each other along the actuation axis.Type: GrantFiled: June 28, 2018Date of Patent: October 20, 2020Assignee: WALLMEK I KUNGÄLV ABInventors: Niklas Wallman, Martin Hasselskog, Sten Johansson

Patent number: 10653878Abstract: An apparatus or method for forming a sterile connection. The apparatus includes at least two sterile tubes each disposed within a flange. Each flange has an external face that completely covers the mouth of the tube. Each flange is designed to be displaced when force is applied to the tube to move the tubes toward one another such that the external face of each flange is displaced radially or axially outwards away from the mouth of the tube. When the external faces are displaced, the external face of each flange opens and tubes connect and form a sterile connection therebetween.Type: GrantFiled: January 8, 2016Date of Patent: May 19, 2020Assignee: Metanova, ABInventors: Alf Löfving, Håkan Samuelsson, Lennart Myhrberg, Sten Johansson

Patent number: 8029023Abstract: A method and a device are provided for contamination-free and/or sterile sealing between two interconnectable connecting elements having opposing openings. Interconnection allows transfer of a fluid between the openings. Sealing elements are arranged on the connecting elements around the openings, and protective films are provided, covering the sealing elements and the openings and adapted to be removed in the final interconnection. The sealing elements are each provided with at least one recess which extends wholly or partly around the associated opening and receives a gas. In use the sealing elements are moved into engagement with each other, interleaved with the protective films, to reduce the volume of the recesses and, thus, increase the pressure of the gas therein. During removal of the protective films, the gas flows out of the recesses to the environment to prevent penetration of contamination into the openings.Type: GrantFiled: February 8, 2006Date of Patent: October 4, 2011Assignee: Millipore ABInventors: Nils Årthun, Sten Johansson, Lennart Myhrberg, Håkan Samuelsson

Patent number: 7922211Abstract: A method and a device are provided for interconnecting, sealed against contamination, the ends of tubes by two cooperating connecting components, each having an inlet and an outlet for connection to each other. The connecting components each have a connecting plane, into which the outlets open, each covered by a protective component, and which are movable into engagement with each other with the outlets facing each other. A locking element, which is slidably arranged on one connecting component, is, in a controlled manner and without interruption of the sliding movement, movable onto the other connecting component to a distinct end position. The protective components are removable by means of the locking element when this is moved, and the outlets are sealingly pressable against each other. The locking element is prevented from moving until a predetermined force is applied in the moving direction.Type: GrantFiled: February 8, 2006Date of Patent: April 12, 2011Assignee: Millipore ABInventors: Nils Årthun, Sten Johansson, Lennart Myhrberg, Håkan Samuelsson
