Abstract: A method is provided for a base station set (NODE B) adapted for RLC and MAC-hs signaling in acknowledged mode (AM), the base station set at least forwarding protocol data units (MAC-d PDU) from a Radio Network controller (RNC) to a user entity (UE), the method comprising the steps of monitoring (1) the MAC layer of the transmission entity of the base station set (1), if a MAC discard has occurred in the MAC layer (3), that is, protocol data units (PDU's) have been deleted in the input buffer of the base station set (NODE B), transmitting (7) a discard notification message from the MAC transmission entity in the base station set to the RLC layer of the radio network controller (RNC), indicative of the discarding of protocol data units. There is moreover provided a method for a radio network controller (RNC) adapted for RLC and MAC-hs signaling in acknowledged mode (AM) and a method for a user entity (UE) adapted for RLC and MAC-hs signaling.

Abstract: A method and an arrangement in which the assemblies or assembly parts like fiber lengths, opto- and optoelectronic components are transferred between processing modules (46). The assembly parts (22) including a fiber length (23, 24) are arranged on a pallet means (14), which is transferred on a track (16) between the different processing modules. A free end (25, 26) of the optical fiber length is picked up by a robot device (40) and is processed at one of the processing modules. Finally, the robot device holding the fiber end and the pallet means are transferred to another processing module in a common sequence.

Abstract: A coupling device for a tractor provided with a three point hitch. The coupling device has a first coupling frame, and a second coupling frame, provided with at least an upper and two lower fastening links for hinged fastening of a tool, the first coupling frame being provided with a first coupling element in longitudinally and directionally variable rotation connection with the rotating shaft of the tractor. The second coupling frame is provided with a second coupling element being rotatably connectable with the first coupling element, to transfer the effect of the rotating shaft to the tool. The coupling frames are provided with cooperating upper and lower fastening elements. The upper fastening element of the first coupling frame consists of two fastening hooks turned from the tractor, provided at a spaced horizontal distance from each other symmetrically from the vertical symmetric axis of the coupling frame, converging upwards towards each other.
