  • Patent number: 6240852
    Abstract: A highway-vehicle system for high speed travel which comprises a below-ground structure defining a cavity and a narrow slot extending upwardly therefrom to the roadway surface. Each vehicle in the system is equipped with a projecting member which, in its folded configuration, can be lowered into the slot. The projecting member includes a pair of stabilization wheels and a pair of hydraulically or pneumatically-actuated brake shoes. Once the projecting member has been lowered into the cavity, the wheels automatically unfold, so that they assume horizontal positions and press against opposing sidewalls of the cavity. With the wheels so deployed, the vehicle can be safely driven during high speed cornering and under windy conditions. The wheels can also be used to automatically steer each vehicle. In addition, the wheels are used to conduct electricity in the cavity sidewalls as part of the power takeoff for an electric vehicle.

  • Patent number: 6227336
    Abstract: A linear guide having a carrier body that can be moved along a guide track is provided having a brake device with brake shoes acting upon the guide track and a piston which is located in a pressure chamber which can be displaced by a pressure medium in the carrier body. The brake device has a spring acting upon the piston. Pressure plates are provided in the carrier body which are pressed against the brake shoes located on the guide track by the spring when the piston is not being subjected to the pressure medium. This results in a linear guide whose carrier body can be mechanically and reliably locked on the guide track in case of emergencies such as pressure medium outages.

  • Patent number: 5209165
    Abstract: In a friction buffer stop, each side wall of the buffer structure has at its lowermost edge mutually spaced slots extending parallel to the adjacent rail, each slot being directly opposite to and of the same length as a slot in the other side wall. Pairs of transversely spaced two-part clamps detachably secure each side wall to the rails. Each clamp comprises a pair of side plates clamped on opposite sides of the rail by a clamping bolt passing through one of the mutually spaced slots. The slots engaged by the bolts of each pair of clamps are identical in length; and the slots engaged by the bolts of each pair of clamps, except the first pair of clamps, are longer than slots engaged by the bolts of an adjacent upstream pair of clamps.

  • Patent number: 4785739
    Abstract: In a tracked transportation system independent cars are drawn along by a common cable. A car comprises a rolling chassis with a cabin suspended above the chassis by a set of chains. The chains are coupled to a shaft forming apparatus for weighing the cabin and connected to an assembly for gripping the cable. The coupling between the chains and the gripping assembly can be released by a trigger device fixed to the track and operated by remote control to lower the cabin relative to the chassis and so achieve emergency braking.

  • Patent number: 4721044
    Abstract: A rail car skid insertion device for remotely inserting a skid onto a rail head of a rail spur to impede movement of a rail car is disclosed. The device includes a skid removably attached to a carrier arm mounted on a slide bar. The skid is attached to the carrier arm at a safe distance from a rail head. The slide bar may then be translated such that the skid is positioned on the rail head. The removable attachment allows a wheel of a moving rail car to drag the skid off of the carrier arm. The skid prevents the rail car wheel from rotating, thereby reducing the speed of the rail car. After the skid has been removed from the carrier arm, the slide bar may be retracted, and another skid attached, thereby allowing remote insertion of another skid onto the rail head after the wheel of the rail car moves from the skid, the skid rails on the rail head and falls automatically on the road bed at one side of the rail.

  • Patent number: 4498561
    Abstract: A retractable wheel chock assembly for railway wagons comprises the combination of a wheel chock (12) designed to act on the flange of a wagon wheel, and a friction brake (36) attached to the wheel chock and sliding along a guide rail (3) mounted just outside the railway track (4) on which the wagon is running. The wheel chock (12) is at one end of a cantilever arm (10) that can be swung out over the railway track or inwardly over the guide rail. Both the cantilever arm and the friction brake are mounted on a carriage (1) that is movable longitudinally of the guide rail, and a linkage between the arm and the brake ensures that the brake is actuated in response to the reaction force of the wagon wheel on the wheel chock. The wheel chock may be extended over the railway track, advanced along the track into abutment with a wagon wheel and braked, all in a single operative movement.
