Abstract: The invention relates to a rail system for large turret bearing comprising a turret bearing support structure (7), a rail support ring (13) The invention relates to a rail system for large turret bearing comprising a turret bearing support structure (7), a rail support ring (13) provided with a L-shaped cross section comprising an inward directed wedge mating face (46), at least two rings of radially elongated segment bolt holes (45), and an outermost ring of wedge bolt holes, a plurality of rail segments (20) together forming a complete circle with an outer radius slightly smaller than the radius of the wedge mating face (46) of the rail support ring (13). Each segment (20) comprise a sloped outer wedge mating surface (38), a downward facing contact surface with threaded bolt holes corresponding to the bolt holes (45) in the rail support ring (13), an upper largely horizontal surface, and an inner largely vertical surface. Furthermore, the rail system comprises trapeze shaped wedges (43) each with at least one bolt hole and corresponding bolt (s), adapted to be tightened down between the wedge mating face (46) of the support ring and the sloped outer wedge mating surface (38) of the segments, and rail bolts (24) for fastening the rail segments (20). Furthermore the invention comprises a method for mounting the rail system and a method for replacing a rail segment.The invention relates to a rail system for large turret bearing comprising a turret bearing support structure (7), a rail support ring (13) The invention relates to a rail system for large turret bearing comprising a turret bearing support structure (7), a rail support ring (13) provided with a L-shaped cross section comprising an inward directed wedge mating face (46), at least two rings of radially elongated segment bolt holes (45), and an outermost ring of wedge bolt holes, a plurality of rail segments (20) together forming a complete circle with an outer radius slightly smaller than the radius of the wedge mating face (46) of the rail support ring (13).

Furthermore the invention comprises a method for mounting the rail system and a method for replacing a rail segment. Apparatus for feeding doses of fluidisable materials comprising one upper Intel pipe (1', 1"), one lower outlet pipe (2', 2") and a Pausing (6',6"). and a fluidising element (5',5") for controlling outflow of materials through the outlet pipe (2', 2"), The apparatus further comprising a control volume constituted by a chamber (3',3") between the Intel pipe (1', 8") and the outlet pipe (2',2") and a fluidising element (4', 4") for controlling inflow of materials Into the chamber (3', 3"). A diverter (7',7") la arranged between the Inlet pipe (1',8") and the outlet pipe {2', 2") defining said chamber (3', 3") between said Inlet pipe (1',8") diverter (7',7") the housing (6', 6") and the fluidising element (5',5"). The Invention also relates to a method for feeding doses of fluidisable materials by the apparatus.
