Patent number: 10479140Abstract: A wheel lifting device comprising a base structure with support means for being supported by a ground surface and a lifting frame with at least one wheel support member and a frame leg which extends upwardly at an angle to the ground surface. A link mechanism is connected to the base structure and to the lifting frame and a pivotal manoeuvring lever is connected to the link mechanism for lifting the lifting frame relative to the base structure. The blocking device for locking the manoeuvring lever at any desired pivotal position comprises a weight which is slidable along the frame leg and arranged to intersect the pivotal movement path of the manoeuvring lever and to be brought into frictional engagement with the frame leg when influenced by a force generated by the manoeuvring lever in order to block the lifting frame from downward movement relative to the base structure.Type: GrantFiled: May 3, 2018Date of Patent: November 19, 2019Assignee: AB Kompositprodukter VikmanshyttanInventor: Mats Lindgren

Patent number: 6992786Abstract: The present invention relates to a method and a system for online creation and ordering of customized material for printing, where each customer at front end, through a computerized interface, participates in the process of creating, editing, proof printing and finally ordering print-ready files through Internet, via a printing service provider which automates the production of the print-ready files, and where print shops carefully chosen by the printing service provider automatically receives the print-ready files directly into their printing press. A PDF engine uses two XML files to create a customer PDF document for printing on demand. One XML file, the data XML file, comprises the data and it's typing for printing, and is created by the customer through the computerized interface. The second XML file, design XML file, comprises a description of how said data can be positioned and formatted, in a created document by the customer through said interface.Type: GrantFiled: July 10, 2000Date of Patent: January 31, 2006Assignee: Printon ABInventors: Emil Breding, Henrik Kihlberg, Mats Lindgren, Niklas Grunbaum

Patent number: 5896621Abstract: A handle for hand-held tools, particularly files, that have an end portion (3) for insertion into the handle (1). The handle includes at least two parts (4, 5) which are separated in the insertion direction of the end portion of the tool and includes end-portion guides (6). One guide has the form of a hole (6) in one handle part (4). A surface on the guide in the other handle part (5) intended for coaction with the end portion (3) of the tool is displaced laterally in relation to a corresponding surface in the hole (6). The two handle parts (4, 5) are resiliently movable relative to one another, to permit reduction in the displacement between the surfaces in conjunction with inserting the end portion (3) of the tool into the handle (1). The end portion of the tool is automatically clamped firmly in the handle as the handle parts tend to spring back to their original positions.Type: GrantFiled: May 5, 1997Date of Patent: April 27, 1999Assignee: AB Kompositprodukter VikmanshyttanInventor: Mats Lindgren
