Abstract: A debarking machine of annular rotor type comprises a stator (1) and a rotor (2) that has an opening (4) for the longitudinal feed of logs and to which a number of machining tools are connected. Each tool is actuated by a spring device that usually strives to hold the tool flexibly pressed against a log passing through the rotor in order to peel the bark from such. As necessary, the individual tools can move together in a direction outward from the log against the force of the spring devices. A ring element (18), which is mounted relative to the rotor and usually follows such during normal operation, is situated between the rotor (2) and the stator (1). Via a transmission (21), this ring element is connected to the drive shaft (23) of a pump (24) that is mounted on the rotor and always follows such. The stator (1) has a braking device (26) to reduce the speed of the ring element in relation to the rotor speed as necessary (suitably to zero) and then activate the pump (24) via the transmission so that this in turn transfers a force to the machining tool that overcomes the force exerted by the spring device and produces said oscillation of the tool in a direction outward from the rotor centre.<IMAGE>

Abstract: Pieces are cut off the end of a long web by first impaling the leading end of the web on a crosswise circulating needle bar that is then moved downstream from a cutting to a holding section. Then at the cutting station another such circulating needle bar and a noncirculating needle bar are poked through the web, with the noncirculating bar being downstream (relative to the displacement direction of the web) of the circulating bar. Then the web is cut across between the two upstream bars and the noncirculating bar and the downstream circulating bar are dropped down to transfer the piece thus cut from themselves to a transverse needle-chain conveyor. Then the circulating bar is moved back from the downstream holding station to the upstream cutting station while the second circulating bar pulls another piece of the web downstream across above the transverse conveyor.

Abstract: A method for optimizing the use of channels, the changing of channels and handover procedures in a mobile telecommunications system for instance, wherein parameters belonging to the mobile telecommunications system generate the load values for the connections via different channels/base stations between subscribers in a public telephone network and mobile stations in the mobile telecommunications systems. Different kinds of parameters can be compared directly by means of the load values which are combined to provide a total load value for each connection. A first total load value is generated for a connection set-up between one of the subscribers and one of the mobile stations. The total load values for the connection are estimated for alternative channels/base stations and these total load values are compared with the first total load value. The system changes to the channel/base station that has the most favorable load value, on the basis of the comparison. The load values can also be used to optimize the resources within one or more base stations, so that the sum of the load values for the connections within one or more base stations will become the most advantageous.

Abstract: A method and a device for braking the movement of a melt in non-solidified portions of a cast strand during casting of metal. Melt flows into a mould which comprises four copper plates (2, 3) which form a downwardly open casting mould with a substantially rectangular cross section. A static or periodic low-frequency magnetic field (5) is generated across the path of the inflowing melt whereby electric currents are induced in the melt. According to the invention, two opposite copper plates (2) are electrically insulated from each other, and the induced currents are returned via an external return conductor (13) which is connected between the two insulated copper plates (2). The induced currents together with the magnetic field give rise to a force which acts in such a direction that the movement of the melt is braked along the whole width of the mould.
