Abstract: There is provided mechanisms for over the air testing of a radio communications device. A method is performed by a signal generator. The method comprises generating a respective test signal for each of a plurality of receiver units of the radio communications device, wherein each test signal is independently modulated according to a multipath propagation channel model. The method comprises sequentially, and for the plurality of receiver units of the radio communications device, transmitting the test signals over the air.

Abstract: A cone crusher shaft position measurement sensor arrangement is arranged for measuring a position of a crushing shaft of a cone crusher that has an inner crushing shell supported by a crushing head mounted on the crushing includes a target means arranged to be connected to the crushing shaft and to move in a horizontal plane in concordance with the movement of the crushing shaft. The target means includes a sensor target. The sensor arrangement also includes at least one first sensor element for sensing the horizontal position of the sensor target.

Abstract: A method of controlling the crushing of material in an inertia cone crusher includes the step of charging material to be crushed from a feeding hopper to a crushing chamber formed between an inner crushing shell being supported on a crushing head, and an outer crushing shell of the inertia cone crusher. An unbalance bushing, which is provided with an unbalance weight and rotatably connected to the crushing head by a drive shaft, is rotated such that a central axis of the crushing head gyrates about a gyration axis. The number of revolutions of the unbalance bushing is sensed using an rpm sensor. The number of revolutions of the unbalance bushing is controlled by a control system and the material is crushed in the crushing chamber.

Abstract: A cone crusher includes an outer crushing shell and an inner crushing shell forming a crushing gap there between. The outer crushing shell is supported on an upper frame member in vertically adjustable engagement with a lower frame member. A sensor arrangement having a sensor element is provided for measuring the vertical position of the outer crushing shell. The cone crusher further includes a target means arranged to be detectable by the sensor element, wherein one of the target means and the sensor element are arranged to follow vertical movement of the upper frame member and to move in relation to the other one of the target means and the sensor element. The sensor element includes a vertical sensing array which extends in a vertical direction along at least a portion of a range within which the target means may be moved upon adjusting the vertical position of the upper frame member.

Abstract: A method for providing data related to the operating condition of a machine part of a liquid processing system is provided. The method comprises the steps of: selecting at least one machine part of the liquid processing system; calculating an expected remaining usable time based on an estimated life time of the machine part; determining at least one real-time operating condition of the at least one machine part; and providing the expected time for maintenance and the at least one operating condition as data for enabling a decision whether to perform maintenance of the machine part or not.

Abstract: A cylinder head (1) for an internal combustion engine, the cylinder head (1) having a top face (1a), a bottom face (1b) arranged to be connected to a cylinder block, a lateral exhaust flange face (1c) arranged to be connected to an exhaust manifold (17), a second lateral face (1d) being opposed to said lateral exhaust flange face (1c), a front face (1e) and an end face (1f).

Abstract: Clamp (10, 20, 30) for connecting a hose (13, 23, 33) to a pipe end (14, 24, 34) with an asymmetric cross section. The clamp (10, 20, 30) comprises at least two sections (11 and 12, 21 and 22, 31 and 32) that are shaped so that the clamp (10, 20, 30) will have the same shape as the cross section of the pipe end (14, 24, 34) when the two sections are put together. The clamp (10, 20, 30) is made of aluminium or a plastic material.
