    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.

    Abstract: A system to control the movement of carts in an airplane. It has a set of tracks in which a set of roller wheels is placed. The roller wheels are attached to the bottom of a typical cart. A releasable locking system is used to control the cart as before. In one embodiment, the system has a cart release mechanism to remove it from the tracks for servicing and storage. The system uses a “pop-up” ramp that is embedded in the bottom of the track at specific locations. At these locations, the top of the track is large enough to allow the wheels to pass out of the track. Thus, to remove the cart, the ramps are deployed and the cart is pushed up the ramps until all four wheels have come out of the track.

  • Patent number: 5400717
    Abstract: Track sections of industrial conveyor systems are joined in end-to-end relationship using alignment devices that ensure that the internal running surfaces of the rail flanges of the track are free from irregularities at the track joints. Tubular bushings are located at the ends of the sections on adjacent external surfaces of the rail flanges out of running contact with the moving conveyor components. When the bushings are brought into register and united to form a connection, proper alignment is achieved and maintained without the need to weld the track sections together at each joint. This provides a modular track configuration to facilitate the installation and maintenance of conveyor track systems.
