Abstract: Coupling for connecting of pipe shaped sections comprising a first pipe section and a coupling device arranged to connect the first pipe section with a second pipe section. When joined together, the first pipe section is arranged to receive the second pipe section in such a way that the first pipe section and the second pipe section forms an overlapping region. The wall of the first pipe section is provided with a through hole in the overlapping region and the coupling device is adapted to protrude through the hole. The coupling device is at least at one of its ends slidably attached in such a way that a rotational displacement around, and essentially perpendicular to, the axial direction of the pipe section will give rise to a change between a first position for locking, wherein said coupling device is protruding on the inner side of the first pipe section, and a second position for release wherein the coupling device essentially not is protruding.

Abstract: A method for mounting a bearing in a wheel hub, and a wheel manufactured by the method, wherein a wheel body is placed in a mold with a tubular-shaped bearing placed in a hub part of the wheel body, annular tread is die cast around the outer periphery of the wheel body, preferably at the same time as the bearing is fixed in the hub part of the wheel body by a die casting at least partly surrounding the bearing. The hub part in the wheel comprises axially separated, annular arranged support members having at least one axial opening and engaging radially a casing part of the bearing. The bearing is thereby axially fixed by a die cast, elastic plastic material in a space between the outer casing part and an inner wall surface of the hub part.

Abstract: Indicator device for determining the distance between a workpiece set up in a working machine, and a tool set up in said machine. The device comprises a lower portion (2) with an underside (13) which is adapted to lie against the workpiece, and an upper portion (1) with a topside (8) against which the tool is intended to come into contact, the topside being parallel to the underside (13) of the lower portion and movable towards the underside against the efect of a resilient force. A voltage source (4) and an indicator (5) are provided. The underside (13) and the topside (8) are electrically conductive but are insulated from each other, and the indicator (5) and the voltage sorce (4) are electrically coupled so that the indicator (5) provides and indication when a circuit (16) between the topside (8) and the underside (13) is closed via the workpiece, the machine, the tool, the voltage source (4) and the indicator (5).
