| 20090095188 | Rail Threading Mechanism - A rail threading mechanism for a rail handling vehicle includes a thread box mounted on the outer end of a manipulating arm. The thread box includes a platform and a pair of jaws pivotally connected to the platform and moveable between open and closed positions. The platform includes a support roller for rollingly engaging the flat bottom of a rail. Each jaw include a plurality of jaw rollers positioned for rollingly engaging a rail positioned on the support roller when the respective jaw is in the closed position. The jaw rollers on each jaw preferably include a pair of base rollers positioned for engaging an edge of the base of the rail, a pair of flange top rollers positioned for engaging a top surface of the top flange of the rail, and a flange side roller positioned for engaging an edge surface of the top flange of the rail. | 04-16-2009 |
| 20090193950 | Automatic Rail Saw - An automatic rail saw includes a frame adapted to be lowered onto a railroad rail by a crane. A lower end of the frame includes a channel for receiving the rail. A releasable clamp mechanism on the frame is operable to clamp the rail in the channel. A saw blade is mounted on the frame for rotation about a rotational axis and for linear movement along a cutting path extending through the channel for cutting of the rail with said blade. The blade is driven by a blade motor and moved along the cutting path by a drive motor. A control system adjusts the rate at which the saw blade moves along the cutting path based on measured parameters such as blade speed, current draw of the drive motor and hydraulic pressure at the drive motor. | 08-06-2009 |
| 20100107925 | METHOD AND APPARATUS FOR APPLYING RAILWAY BALLAST - A method and apparatus for spreading ballast along railways makes use of an inertial measurement system to determine where to apply ballast from a hopper car. A variety of techniques can be used to determine the location and speed of the ballast spreading train, including manual or automated visual techniques, laser technology, radar technology, radio frequency transponders, magnetic sensor, thermal imaging and aerial photogrammetry. The invention also contemplates “on the fly” surveys and terrain profiling using lasers or radar. | 05-06-2010 |
| 20110041721 | RAIL TRAIN - A rail train for supporting multiple sticks of ribbon rail comprises a plurality of rail support cars having a single, centrally positioned rail support stand wherein adjacent rail support cars are supported on shared trucks. End cars include a tunnel for supporting the rails near their ends and one or more rail support arms pivotal at a first end about two axis and supporting a rail guide assembly at a second end for supporting a rail as it is pulled of the rail train. A rail tie-down car utilizes spring-loaded, hydraulically actuated clamp assemblies to clamp individual rails to the tie-down car. Each clamp assembly incorporates at least two clamp members which act opposite one another to prevent the rail secured in place by the clamps from sliding in either longitudinal direction. | 02-24-2011 |
| 20110129314 | CLAMP ASSEMBLY - A clamp assembly for supporting multiple elongate rails in a rail tie-down car utilizes spring-loaded, hydraulically actuated clamp assemblies to clamp individual rails to the tie-down car. Each clamp assembly incorporates at least two clamp members which act opposite one another to prevent the rail secured in place by the clamps from sliding in either longitudinal direction. | 06-02-2011 |

| 20080228352 | VEHICLE SUSPENSION SYSTEM AND METHOD OF OPERATING SAME - A suspension system for use on a vehicle having two or more rear axles. The suspension system includes a plurality of gas springs and plurality of height sensors capable of outputting signals having a relation to distances between the respective ends of the respective first and second rear axles and the sprung mass of the vehicle. A control system adapted to selectively inflate or deflate respective ones of the plurality of gas springs to thereby adjust a leveled orientation of the sprung mass. The control system includes a controller that is adapted to determine a rear axle vertical offset and a rear axle articulation offset. The controller is adapted to determine whether conditions are appropriate for adjusting the suspension system by comparing the rear axle vertical offset and/or the rear axle articulation offset to a corresponding vertical offset threshold and/or an articulation offset threshold. A method is also included. | 09-18-2008 |
| 20080290617 | Gas suspension system and method - A method of operating a gas suspension system includes generating a first quantity of gas having a storage pressure and transferring the first quantity of gas into the pressurized gas storage device such that a second quantity of gas having approximately the storage pressure remains in a transfer pathway. The method also includes determining that a condition exists for venting gas from the gas spring assembly and placing the second quantity of gas into fluid communication with a quantity of gas having said spring pressure. The method further includes waiting until an approximately equilibrium pressure has been reached, and then actuating a third control device to exhaust at least a portion of the gas from the suspension system. A gas suspension system adapted to perform the method is also included. | 11-27-2008 |
| 20100030425 | METHOD AND SYSTEM FOR ALIGNING A VEHICLE WITH AN ARTIFICIAL HORIZON - A method and system for positioning a vehicle chassis in approximate alignment with a predetermined datum are provided. The vehicle includes a first longitudinal end adapted to be pivotally connected to a substantially fixed point and a second longitudinal end including at least one axle and an operatively associated two-corner fluid suspension system. According to the method, the fluid suspension system controls the alignment of the vehicle chassis to be aligned with an artificial horizon represented as the predetermined datum. | 02-04-2010 |
| 20110093239 | VEHICLE WEIGHT SENSING METHODS AND SYSTEMS - Disclosed are vehicle weight sensing methods and systems. According to one aspect of this disclosure, provided is a method of characterizing a vehicle to determine gross axle weights by accessing a computer readable database which correlates a plurality of pressures associated with fluid suspension members incorporated into the vehicle. | 04-21-2011 |
| 20110115140 | GAS SPRING AND GAS DAMPER ASSEMBLY AND METHOD - A gas spring and gas damper assembly includes a first end member, a second end member and a flexible wall that at least partially defines a first spring chamber therebetween. A damping chamber wall at least partially defines a damping chamber. A damper piston is received within the damping chamber and is operatively connected between the first and second end members and within the first spring chamber. A suspension system that includes a gas spring and gas damper assembly as well as a method of assembly are also included. | 05-19-2011 |
