  • Patent number: 5988073
    Abstract: A railway waggon comprises on one hand a load carrier (2) composed of two carrying beams (12, 12') and an intermediate, load-receiving platform part (13), and on the other hand bogies (3) with wheels (4) for railway tracks (5). The platform part (13) is located on level with or below the carrying beams (12, 12'), which at their ends change into jibs (15, 15') located above the beams so that these may be applied on top of the bogies (3), without the platform (13) being markedly distanced vertically from the wheel base of the bogies. The load carrier (2) is on one hand coupled to the bogie via a joint (25, 26) in order to allow for relative turning motions between the bogie and the load carrier, and on the other hand detachably connected with each one of the bogies, in order to, in an inactive state in connection with loading and unloading, be able to be displaced with each end laterally.

  • Patent number: 5844414
    Abstract: A system and a method for moving a measuring device (4, 30) to a plurality of positions above a test object (12), e.g. an electrically or electronically equipped printed board, at which the EMC, of the test object (12) is measured and later stored in a memory together with the position of the measuring device. The system includes a computer (18) and a measuring device (4, 30). The positioning device (8) moves the measuring device (3, 30) across the test object (12) from one position to another, wherein the number of positions and their coordinates are preselected and stored in a computer (18) for a later repetition of the measurement. Each position is assigned with a measurement value which is stored in the memory of the computer (18) together with the coordinates of the measuring device (4, 30). At each position, the power to the control devices is shut-off, in order to minimize interference with the measurements.

  • Patent number: 5186227
    Abstract: A driving device comprises at least one chain (16) in the form of a closed loop. The chain is connected to at least one driving member arranged to cause the chain to orbit. Furthermore, the chain is laid over diverting members which in combination with the driving member determine the form of the loop. A rubber element (17) is arranged on the face of the chain located outermost in the loop and forms a configuration generally enclosing the chain loop. The rubber element (17) is in a driving force transmitting engagement with the chain (16) to be caused to orbit thereby. The rubber element (17) serves for engagement with for instance tree trunks over a large surface.

  • Patent number: 4515192
    Abstract: A device for processing trees or the like comprises two grabbing members pivotable towards and away from each other about hinges and carrying rolls provided to feed trunks at an angle to the pivotal plane of the grabbing members. The hinges are, in a base of the device, arranged movable towards and away from each other without simultaneous pivoting of the grabbing members.
