Abstract: A live steam passage of double-shell design for steam turbines is disclosed. According to the present invention, the steam passage is welded as a welded-in insert (1) onto the outer housing (9) of the turbine. The piston ring supoprt sleeve (2) with the piston rings (4) slides as a separate part in a sleeve (5), which the sleeve (2) is screwed onto the welded-in insert (1) with locking screws (3). A threaded ring (6) provided with a high collar holds the sleeve (5) in place in the inner housing (7) of the turbine. The live steam passage according to the present invention can be used in steam turbines, including throttle-controlled steam turbines with inner housings.

Abstract: An arrangement for storing and removing bulk material in a round pile, in which a truss is rotatable about a vertical axis on a substructure. The truss carries a material depositing belt and a bulk material receiver which is pivotable in a vertical direction. A counterweight on the truss balances weight. The substructure is hopper-shaped. The truss is mounted on the substructure by a bearing, and rollers carry the truss which runs on the substructure. The bulk material receiver is in the form of a drag that conveys to a hopper of the substructure. This hopper has a bottom with a conveying medium under which a conveyor belt runs. The bearing has a large diameter annular track that is elevated on posts on the substructure. A rotatable plough located at the bottom of the hopper is the single conveying element on the hopper bottom.
