  • Patent number: 6857373
    Abstract: A variably curved track-mounted amusement ride having at least one outside curve and at least one inside curve, each lying substantially within a vertical plane and each having an axis of symmetry which is substantially horizontal. Preferably, the top curve is an outside curve; and preferably inside and outside curves alternate with each other. Also preferably, before the first curve, between each outside curve and each inside curve, and after the last curve is a substantially straight segment which slopes downward. The vertical distance occupied by an outside curve is less than that occupied by an inside curve. The track can retain a cart which runs on the track no matter what the orientation of the body of the cart is with respect to the track. Any means that is well known in the art can be used to raise the cart to the beginning of the track.

  • Patent number: 6154973
    Abstract: A method for correcting the track geometry of a track, includes measuring an initial track position of the track following lifting of the track and tamping under the track, and so computing a final desired track position as to eliminate long-wave alignment errors of the track geometry. Subsequently, corrective values are determined commensurate with a difference between the final desired track position and the initial track position, and the track is stabilized by lowering the track in a controlled manner into the final desired position and controlling in response to the corrective values the static load and/or transverse vibration acting on the track, thereby eliminating during track stabilization in particular long-wave geometrical track errors.

  • Patent number: 5435253
    Abstract: A vacuum highway seal provides an effective barrier for maintaining a separation between the atmosphere and a vacuum highway, which allows vehicles to reach near orbital speeds on the surface of the earth. The vacuum highway seal is composed of a pool of water with a pipe extending from several feet below the surface to approximately forty feet above the surface of the water. Water is pushed by atmospheric pressure from the pool to approximately thirty two feet above the pool into the pipe. A vehicle is loaded with cargo and/or people at the dock in the pool, then is submerged and travels to the entrance of the pipe underneath the water. The pipe is tapered and sloped to allow an easy transition from the pool into the vacuum highway. As the water ballast used to submerge the vehicle is expelled the vehicle is accelerated to the surface of the water and the vacuum highway beyond. Once in the vacuum highway a second propulsion system is used to propel and lift the vehicle.

  • Patent number: 5048424
    Abstract: A vehicle for replacing selective ties in a road bed uses a conveyor system whereby ties may be picked up from on top of the rails. If the ties are to be used by the particular vehicle, they may be held by that vehicle. On the other hand, the conveyor system allows ties to pass over top of the vehicle such that the ties will be again disposed on top of the rails such that a following tie replacement vehicle may use the ties. By use of a tie replacement or inserter head having two tie clamps, one can more quickly remove an old tie from underneath the rails and replace the old tie with a new tie which has been picked up from on top of the vehicle. Electromagnets are used to hold the tie plates against the rails during the selective replacement of particular ties such that replacement of the tie plates is not usually necessary.

  • Patent number: 5025733
    Abstract: A railroad tie replacing device (10) including a support frame (11) on rollers (22) for movement over a series of parallel railroad tracks (28) supported by railroad ties (29). A main piston or cylinder (15) is positioned such that the stroke of the piston rod is horizontally toward and away from the rails. A gripping mechanism (23) is arranged on the main cylinder rod and is capable of gripping a railroad support to be replaced. The main cylinder and an attached spacer (24) for securing the invention to the rail during operation are lowered over the rail by a lift cylinder (18). Upon operation, the grippers are closed over a tie to be removed and the main cylinder is activated. The outward stroke of the main cylinder piston rod with appended gripper mechanisms pulls the tie from beneath the rails.
