摘要： A mobile ballast cleaning machine comprises an endless bucket chain and a pair of guide arms mounted laterally of the machine frame and guiding the bucket chain between a first position wherein the bucket chain is immersed in the ballast underneath the track ties and extends widthwise transversely of the track, and a ballast discharge position above the track. The width of the bucket chain in the first position transversely of the track is adjustable.

摘要： A rotor is mounted in a casing defining a cylindrical annular interior wall in sealing relationship with the periphery of the rotor. The rotor includes a peripheral cavity mounting a piston for radial movement towards and away from the opposed annular wall surface of the casing. An air-fuel mixture inlet port, a combustion chamber, and an outlet port for burnt gasses are circumferentially spaced about the interior annular wall so that the portion of the peripheral cavity on the rotor between the piston and the interior annular wall is successively placed into communication with the inlet port, combustion chamber, and outlet port as the rotor rotates. A cam arrangement connects the piston with a cam surface on the interior of the casing so that movements of the piston towards and away from the opposed interior annular wall are guided. A fresh air inlet in turn communicates with the peripheral cavity portion under the piston and includes a check valve so that outward movement of the piston draws in fresh air and inward movement compresses the air. The cavity is shaped such that complete inward movement of the piston exposes an outlet portion so that the compressed air can circulate around the piston. With this arrangement, the fuel-air inlet mixture is supercharged by the compressed air during a portion of the compression stroke of the piston and the burnt gasses are in turn purged by the fresh air during an exhaust stroke of the piston. The fresh air inlet also provides cooling for the piston and rotor.

摘要： Each tie of a railroad track has flexurally stiff bracing elements extending in the direction of the track rails into both adjacent cribs. The bracing elements extend along the axis of symmetry extending longitudinally centered between the rails and/or under the rails. Preferably, two or more adjacent ties with the bracing elements are formed into a unit, for instance a cast reinforced concrete unit.
