Abstract: The present invention relates to a method and arrangement to enhance the communication performance in wireless communication systems. The method of the invention provides a method of calibrating at least one first radio node in a wireless communication network. The communication network comprises at least a first radio node and a second radio node, which can be arranged to be in radio communication with each other. The calibration method is based on either at least one estimation of a radio channel or a correction vector/factor, which has been exchanged from one radio node to the other. Whereby inaccuracies and differences in transmit - receive chains are compensated and channel reciprocity is achieved. <IMAGE>

Abstract: A device and a method for stabilizing an elongated metallic strip of a magnetic material when coating the strip with a metallic layer. The strip is transported from the bath in a direction of transport along a predetermined transport path. A wiping device for wiping off superfluous molten metal from the strip applies an air flow in a line across the strip, where the wiping device includes at least one pair of air-knives arranged with one air-knife on each side of the strip. An electromagnetic stabilizing device stabilizes the position of the strip with respect to the predetermined transport path. A sensor detects the position of the strip in relation to the predetermined transport path.

Abstract: A method and machine for the manufacture of packing containers of the type where a number of packing container blanks are successively converted to packing containers, open at the top, which are filled with contents, shaped and sealed. The packing container blanks are advanced intermittently during the processing and filling between the different stations, which means especially in packing machines with several conveying elements, that the driving unit of the machine will be unevenly loaded and that the working of the machine will be uneven and jerky. To overcome this it is proposed in accordance with the invention, that the driving of the different conveying elements should take place asynchronously in accordance with a similar but mutually offset pattern of movement. The one conveying element (6') will then be substantially at standstill during the advance of the second conveying element (6") and vice versa, as a result of which the driving unit obtains an appreciably more uniform torque curve so that uneven operation and consequent wear and noise can be prevented.

Abstract: In the event of a frontal collision, cushioned passenger seats having a back part fixed rigidly onto the seat part must absorb the impact energy of passengers flung forwards and to a great extent reduce it by deformation. In addition, seats of this type, which are subject to considerable wear, should be constructed such that they are easy to maintain. According to the invention, this is achieved in that there is provided between the seat part and the back part a moving joint which is constructed such that it can absorb the impact energy to a defined extent. Moreover, these joint parts also allow a simple exchanging of the back parts and hence easy maintenance of these passenger seats.

Abstract: A height adjustment device is provided which is suitable for combination with a webbing tightener. Unintentional release of the locking engagement by the downwardly directed inertia forces on the slide are avoided in that by means of a compensating mass a compensation force is generated which simultaneously acts on the slide and opposes the inertia forces of the latter. A two-armed lever which is pivotally mounted in its center and to the one end of which the compensating mass is secured converts the downwardly directed inertia forces originating from the compensating mass to an upwardly directed compensation force acting on the slide.
