Abstract: The present disclosure provides a refiner segment (1) for refining of lignocellulosic material. The refiner segment (1) have a surface comprising a plurality of bars (10j) extending along a direction between an inner periphery (17b) of the refining segment and an outer periphery (17b) of the refining segment (17b), and a plurality of dams (11i). Each of the dams extend between a corresponding pair of adjacent bars (10k, 10k+1). The refiner segment (10) comprises at least one dam (11p) that comprises a curved side (11c) facing the inner periphery (17b) of the refiner segment (1). The curved side (11c) have a concave curvature with regard to the inner periphery (17b) to thereby form a rounded section in an area (20) defined by the dam (11p) and the corresponding pair of adjacent bars (10k, 10k+1). The at least one dam (11p) is moreover a three dimensionally extending body. The rounded section created by the concave curvature gives a more robust refining segment.

Abstract: Method and device for centering and temporary fixation of tube parts (1, 5) in relation to each other's interior surfaces. A first tool (9) is centered relative to a tube part interior surface (2, 6) by a radially adjustable centering mechanism (13). The centering mechanism (13) is insertable in the tube part (1, 5). A second tool (10) is centered relative to the first tool (9), by a guiding mechanism (15) which cooperates for centering of the tools (9, 10) relative to one another. The second tool comprises fixing mechanism (17) to fix the exterior surface of the tube part (1, 5) to the second tool (10), and at least one third guide (18) which centers two such second tools (10) relative to one another in their mounted position on respective tube part end (4, 8) and at least one coupling member (19) to connect the two second tools (10).

Abstract: The invention relates to a conveying system for moving containers (14), the conveying system (4) comprising an inclined track (8) and a conveying device (24), where the track (8) has an container inlet (11) at the bottom (12) and an container outlet (15) at the top (16) and where the conveying device (24) is arranged to travel down (R) the track (8) and comprises a container moving unit (54) which after passage below a container (14) moves the container (14) one step up (L) the track (8), the conveying device (24) thus moving one container (14) at a time one step up (L) the track (8) during the downward (R) travel of the conveying device (24). The invention also relates to a tower structure (2) comprising a container conveying system (4), and a method for conveying containers (14) with a conveying system (4).

Abstract: A method and system for updating the available amount of a service to be used by a user in a communications system, wherein a requested amount of a requested service is reserved if it is available. It is detected if a valid delivery of the requested service has been performed, if so, the delivered amount of said requested service is accumulated; and available amount is updated in dependence of the delivered amount.

Abstract: A tracked vehicle, especially a snow scooter, that has two laterally spaced-apart front drive-track assemblies (10), each of which is turnable around a substantially vertical axis and which are coupled for common turning. Each drive-track assembly is carried by a vehicle chassis (11) via a vertically movable link device, which in respect of vertical turning rests against the chassis via a spring-damper assembly (7), and the drive-track assemblies are mechanically coupled by a parallel steering mechanism (23-26), which is maneuverable by a driver of the vehicle.

Abstract: Many software applications are protected from illegal or unauthorized use by the use of a License Manager. All installations of the application are required to obtain a license from the License Manager to run. Software pirates routinely circumvent this copy protection by disabling the call to the license manager or change the code of the application so it seems to have passed the license verification. The present invention makes such efforts ineffective. The installed application cannot run, unless the call to the License Manager is made, since important code and data has been extracted from the installation and must be delivered by the License Manager. Obviously, if the call to the License Manager is disabled or manipulated, the extracted code and data will not be delivered to the installed application and it will not run.

Abstract: A gyratory crusher comprises an outer shell, which should be fastened in a frame included in the crusher, and an inner shell, which is intended to be fastened on a crushing head and to define together with the outer shell a crushing gap for receipt of material to be crushed. Upon fastening of the outer shell a first abutment surface on the outer periphery of the outer shell is brought in a first step to abutment against a first contact surface on the frame. In a second step a spacer member is pressed in for clamping of the outer shell between a second surface on the outer periphery of the outer shell and the frame. A good abutment is provided both at the first abutment. Surface of the outer shell and at the second abutment surface thereof.
