  • Patent number: 8651393
    Abstract: A rail repair insert enables repair of rails and rail-like structures. A rail defect is initially identified and removed as contained within a volumetric material portion so as to form a contoured void while maintaining continuity of the rail opposite the void. A pre-formed insert is then placed into the void thereby effecting a rail-to-insert interface. Current is driven through the interface as force directs the insert against the rail. Resistance heat and pressure weld the insert to the rail. The flash welding aspects remove oxides and other impurities from the interface, and the forge welding aspects create a robust solid state weld. Excess material, whether flash, rail, or insert-based, is removed during the finishing processes to provide a virtually seamless rail repair. The solid state weld repair insert may be used to repair any number of targeted metallic rail-like structures.

  • Patent number: 5611234
    Abstract: The process consists in increasing the height of the rail to the detriment of the thickness of the web (16) and of the flange (18). Firstly, the thickness of the upper part of the web (16) below the head (14) is reduced by machining and, next, the rest of the web (16) and the flange (18) of the rail (10) are heated up and deformed by forging. This process avoids hardness modifications of the running surface of the rail.

  • Patent number: 4657181
    Abstract: A rail for a track-bound vehicle comprising a number of lateral flanges, which can cooperate with a substructure, the flanges extending in an outwards direction from an essentially vertically arranged web provided with a foot, and a portion of a runway rail forming part of a head of the rail and connected with the web. This makes possible a reduction of excavating and substructure work, when laying rails, and a simplified maintenance of the tracks, and in addition also reduces the required number of sleepers. The lateral flanges as seen in the transverse direction relative to the web project to a larger extend than the foot, so that the load operating on the rail will essentially be absorbed by the substructure cooperating with and substantially being located in the area of the lateral flanges.

    Abstract: A monorail system having a rail surface that is provided for small vehicles traversing an incline or slippery areas, with the surface having a plurality of spaced recesses positioned in those areas to form gripping edges for the drive wheels of the vehicles. The recesses may be of a variety of shapes and positioned in different ways to provide the proper grip. The recesses may be mechanically punched into a separate elongated flat bed riveted in appropriate locations to the rail. The punching may be done in such a way so as to form raised ramp-like edges adjacent the recesses to help with the gripping action. The ramp faces face downwardly in inclined areas.
