Publication number: 20220048117Abstract: Chuck arrangement (100) comprising at least three chuck jaws (110, 120, 130), each arranged to be radially displaceable into a respective clamping position in which it applies a radial clamping force (C) to a held workpiece (W). Each chuck jaw comprises fixing means. The chuck arrangement further comprises one respective counterweight (140, 150, 160) associated with each of said chuck jaw and mechanically connected to the chuck jaw in question so that the counterweight pulls the chuck jaw in a pull direction having a non-zero component radially towards a centre of rotation of the chuck arrangement as the chuck arrangement as it rotates. The invention is characterised in that each one of said chuck jaws comprises a radially displaceable backing chuck jaw part (113, 123, 133) and a clamping chuck jaw part (114, 124, 134) and that the backing chuck jaw part is mechanically connected to the counterweight. The invention also relates to a method.Type: ApplicationFiled: January 31, 2020Publication date: February 17, 2022Inventor: Bo Karl Ragnar SVENSSON

Patent number: 10293412Abstract: Backing and clamping chuck jaw part (110, 120), respectively, arranged to engage with each other such that respective contact surfaces (113, 123) a rearranged to come into contact with each other so as to together form a chuck jaw (100) for a chuck (10). The invention is characterized in that the backing chuck jaw part is manufactured from a harder metal material than a metal material from which the clamping chuck jaw part is manufactured, in that a the backing chuck jaw part comprises a convex structure (126), and in that the convex structure is arranged to engage with a corresponding concave structure (116) of the clamping chuck jaw part so that the said concave structure is permanently deformed as a result of an engagement between said structures resulting from the chuck jaw parts first being arranged in a contacting orientation and thereafter being pressed together into an engagement orientation, in which contact is established between said contact surfaces.Type: GrantFiled: March 21, 2016Date of Patent: May 21, 2019Assignee: M.P.C.-System ABInventor: Bo Karl Ragnar Svensson

Patent number: 9937418Abstract: A computer device is described, comprising a computer storage holding a plurality of identifiers, each associated with an address; an interface connected to receive from a first computer device, game data including a completed first board of a game; and a processor configured to receive the game data to access an address associated with a player identifier and to formulate a message for transmission to a second computer device identified by the address, the message including some or all of the game data, whereby a player at the second computer device receives the message prior to accepting an invitation to play the game. Methods for providing feedback and tile selection are also disclosed in the context of a word matching game.Type: GrantFiled: February 21, 2014Date of Patent: April 10, 2018Assignee: KING.COM LTD.Inventors: Christian Murray, Ragnar Svensson, Sebastian Knutsson

Patent number: 9333562Abstract: A chuck-related arrangement having a main portion and chuck jaw portions coordinated with the main portion with associated clamping arrangements, wherein one surface of the main portion is provided with a plurality of tracks adapted to displaceably carry chuck jaw portions. Each one of, and/or a chosen number of, clamping arrangements, are individually to be secured to its element solidly secured to its basic chuck jaw portion exposing a rotational cooperation with an external chuck jaw portion over a central axis of rotation. Two or more of the external chuck jaw portions and their peripheral surfaces are formed as one or more recesses in order to cooperate opposed recesses to form clamping surfaces for a work piece and/or formed as one or more, the recesses intermediately oriented, radially extending elevations, causing cooperative elevations after a rotation to form direct clamping surfaces towards the work piece.Type: GrantFiled: July 17, 2012Date of Patent: May 10, 2016Inventor: Bo Karl Ragnar Svensson

Patent number: 6530578Abstract: The present invention relates to an arrangement (1) for gripping and holding or releasing a material (M), such as material held in a lathe chuck. The arrangement includes a piston-cylinder assembly (2) and a plurality of material gripping and holding or releasing elements, so-called gripping element arrangements (3). The gripping elements are movable between two positions, an open position and a closed position, in response to movements of the piston-cylinder assembly (2). The cylinder-part (22) of the piston-cylinder assembly (2) includes a circular groove (22a) for co-action with rolling support surfaces (12c) associated with said gripping element arrangement (3). The arrangement also includes a separate gripping member (50) which can be readily fitted to the free end-part (3a) of the gripping element (3′) and readily removed therefrom.Type: GrantFiled: September 29, 2000Date of Patent: March 11, 2003Inventor: Bo Karl Ragnar Svensson

Patent number: 6282202Abstract: In traffic processes in a telecommunication system there is internal communication between service controlling entities which may belong to logical nodes in the same or different applications. Such a service controlling entity may be a service process controlling a service for a party of a call. The communication between the service controlling entities is controlled by rules given in a generic protocol. These rules imply lack of messages and use only of protocol parameters in the form of indivisible information transmission elements. Based upon the generic protocol, service protocols are specified, each corresponding to its service, and a protocol managing entity within an application handling the protocol management of a certain service according to the service protocol. The information elements are distributed by a communication service having a parameter distribution function for the protocol parameters, by transferring data between the protocol managing entities.Type: GrantFiled: July 17, 1997Date of Patent: August 28, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Keith Mainwaring, Göran Hågård, Johan Törnström, Mårten Sundquist, Börje Ohlman, Mats Ragnar Svensson, Sven Bäckström, Hans Alvenkrona, Mikael Lennart Hillborg, Leslie Graf

Patent number: 5836633Abstract: The invention relates to an arrangement (6) which functions to grip and hold, or release, material (3) with the aid of a number of movable gripping devices (51, 52). A part (57c) which is intended for coaction with the gripping device (51) has a first supportive surface (57g) and a first through-penetrating hole (57h), and the gripping device includes a narrowed part (51a) which, among other things, provides a second supportive surface (51b) which can face towards the first supportive surface (57g). The two supportive surfaces are adapted to abut one another. The gripping device also has a second through-penetrating hole. The centre line (71, 71') of the two holes can be coordinated for common coaction of the holes with a screw (72).Type: GrantFiled: March 19, 1997Date of Patent: November 17, 1998Inventor: Bo Karl Ragnar Svensson

Patent number: 5791214Abstract: The present invention relates to a tool arrangement (5) which includes a parting tool (6) or the like which is intended to cut off or remove a machined section from the raw material (3) held firmly in a holding device (2). Located adjacent the parting tool (5, 6) on the side thereof that is proximal to the raw material (3) is a bifurcate device (7) which is intended to coact with the edge region (3b, 6b) of the raw material that lies proximal to the machined section, at least when parting of the machine section (3a) is completed, so that upon axial movement of the parting tool and/or bifurcate device a given length of raw material will be withdrawn from the holding device (2). The invention also relates to a method of moving the raw material out of the holding device.Type: GrantFiled: April 5, 1996Date of Patent: August 11, 1998Inventor: Bo Karl Ragnar Svensson
