    Abstract: An electrically insulating mechanical joint checker for mechanical joints connecting rails of following track segments of a railway line, each track segment forming part of a track circuit. The track segment includes electric signal transmitting units and receiving units for transmitting and receiving train presence detection signals within the track segment and/or relating communication signals between the train and the track segment. The train presence detection signals and communication signals include a further joint detection signal, generated and transmitted by the transmitting units and received by the receiving units belonging to the same track segment, the joint detection signal relating to the track segment being different at least in respect to the one relating to the adjacent track segments. A method to detect a failure or breakage of a mechanical joint inside a track segment is also disclosed.

    Abstract: The invention refers to an arrangement of a valve and a pressure vessel. The valve has a housing with at least an opening, a plunger slideably positioned in the housing, a control mechanism to cause plunger movement. The pressure vessel has an exterior surface with at least an opening. The valve is connected to the at least an opening of the pressure vessel. The plunger has at least a first part with a larger size and a second part with a smaller size. The first part of the plunger is positioned outside of the pressure vessel in all valve configurations.

    Abstract: A system for controlling a level crossing between a railway track and a road, the system comprising a first couple of transmitters and a second couple of transmitters in proximity of a level crossing area; a first couple of receivers and a second couple of receivers opposite to the transmitters with respect to the railway track, the first couple of transmitters and receivers located on a first side of the road and the second couple of transmitters and receivers located opposite to the first side, a control unit sending and receiving signals from said transmitters and receivers, wherein each couple of transmitters transmits a first beam from a first transmitter towards a corresponding first receiver, and a second beam from a second transmitter towards an opposite second receiver, the control unit activates sending at least one second beam and sends a warning message and/or close bars of the level crossing upon interruption of at least one first beam due to the presence of the train on the railway track.

    Abstract: The invention relates to a pulverized coal burner for a steam generator. The pulverized coal burner has a fuel duct, through which pulverized coal is conveyed with the aid of a carrier gas. The pulverized coal emerges together with the carrier gas at a fuel duct outlet. The pulverized coal burner furthermore has at least one core duct and at least one secondary duct. Air or oxygen flows through the core duct and the secondary duct, emerging at the core duct outlet and at the secondary duct outlet. The core duct outlet, the secondary duct outlet and the fuel duct outlet together form a burner outlet. The pulverized coal burner has at least one plasma ignition torch embodied integrally with the pulverized coal burner. The outlet of the at least one plasma ignition torch is arranged in the plane of the burner outlet or offset downstream in relation to the direction of flow of the pulverized coal. The plasma flame produced by the plasma ignition torch is thus located outside the fuel duct.
