    Abstract: An overhead mass transportation system for cities and urban areas may be particularly suitable for environmentally acceptable, or “green”, systems because it can be used to produce power by an optional super solar system deployed, for example, over the tracks. The mass transportation system may meet many current economic and environmental needs. In many urban areas around the world, the mass transportation system can replace buses and taxis on the street, with their noise and pollution, and reduce the use of oil and fuel. The system can also be used for inter-cities transportation, where in can dispense with the need to carry large amounts of fuel for long distance transportation. The system may also be suitable for areas with challenged trains, such as those areas with a high level of floods, snow, or the like. Furthermore, the system may be suitable for desert transportation or transportation over waterways or between islands.

  • Patent number: 6708622
    Abstract: A rail mounted patient lift comprises a ceiling mountable rail 10, a carriage 16 mounted for displacement along the rail, a flexible elongate support element and power operated lifting means for extending and retracting the support element relative to the carriage. The rail 10 comprises a plurality of rail sections 10a, 10b which in use are suspended from a ceiling with a gap 13 therebetween at a position where the rail 10 is to cross the path of a curtain 14. Each rail section has at least one pivotable flap 19 engageable by the carriage 16 as it moves along the rail. The flap 19 of one of a pair of adjoining rail sections is pivotable by the carriage as it moves in one direction to bridge the gap between the two sections and the flap of the other of the pair of adjoining rail sections is pivotable by the carriage as it moves in an opposite direction to bridge the gap between the two rail sections.

  • Patent number: 6655297
    Abstract: In a transfer system using movable bodies supported and guided by a rail through a plurality of guided devices so that they are capable of moving in a given path, when a movable body taken out from the given path is transferred to a separate given path or restored to the original given path, the movable body needs be separated or joined while being longitudinally moved, thus requiring a long path for separating or joining. The invention provides a system comprising a group of guided devices relatively turnably connected to main bodies of the movable bodies through vertical shafts, a plurality of divisional rail bodies capable of supporting the group of guided devices and disposed in a set path portion in the given path, turning means for turning these divisional rail bodies around vertical axes, and a group of transverse rail bodies disposed laterally of the set path portion such that the divisional rail bodies turned for separation from the rail can be connected.

  • Patent number: 6202566
    Abstract: A high-speed high-capacity transportation system is composed of an elevated inverted U-shaped electrified guideway that provides traction and capture surfaces for wheeled motive modules that ride within. Payloads are suspended below the motive unit using a narrow flange. Motive units use flat wheels which ride on flat surfaces of the guideway. The wheels and electric power pickups constitute the only mechanical contact between the vehicle and guideway. Sensors on the motive unit provide position information to an electronic control subsystem which directs the steering of the motive units wheels so as to maintain the desired path through the guideway. As an option, one or more auxiliary wheels can be brought into contact with running surfaces located at the top of the inverted U for additional traction and stability. The payload unit is connected to a the motive unit by way of a hinge that allows the payload to swing laterally.
