A transportation system uses a carrier conduit in the form of a long tube or channel in order to drive a vehicle by air pressure. A carrier having end plates obstructs the travel of air through the carrier conduit. Pressure differentials formed within the carrier conduit serve to propel the carrier through the carrier conduit. By rollably supporting the carrier within the carrier conduit, friction is reduced between the carrier conduit and the carrier. The carrier may be magnetically coupled to a vehicle having vanes and a set of track- or rail-engaging wheel assemblies on vanes. The vanes may pivot upon the vehicle and serve to allow the vehicle to rollably or slidably couple to the carrier conduit track. The motion of the carrier serves to propel the vehicle along the carrier conduit track as the vehicle is magnetically coupled to the carrier. Composite materials used to construct the carrier conduit may allow for such magnetic coupling without the interference that might occur through the use of ferromagnetic materials or the like. The carrier conduit may be mounted upon pillars or pylons and sources of pressure may either be present at either end of the carrier conduit, distributed at propitious points there along, or incorporated into the carrier.

This invention is a pneumatic mass transportation system on the cutting edge of technology employing a combined cycle turbine power system with digital controls to effect acceleration, deceleration and train propulsion. The combustion turbines can be adapted to use alternative fuels including bio fuels as they are developed. The heat recover steam generator will recycle the hot exhaust gasses from the turbines to generate electricity to be used by the system. The multi-car train is propelled by differential air pressure forward and aft of the vehicle in the pneumatic tube. Air propulsion is achieved by large in-tube impellers driven by the turbines. A digital control system will operate the pitch of the impeller blades and the vacuum/pressure release valves in the tubes to produce full movement control of the trains.

A mass transit system includes a plurality of pedestal-mounted rings which provide a support through which a vehicle travels. The pedestals are spaced apart on the ground, but no rail or connecting structure on or above ground is required. An underground conduit carries electrical and communications cable that connects the pedestals together. The rings include a plurality of rollers to drive, guide and stabilize the vehicle at lower speeds. For higher speeds flywheels are mounted on the pedestals. The flywheels are preferably driven by an electrical motor, which engages a friction or clutch plate on the vehicle separate from the rings. The friction plate or linear clutch is mounted separate from the rings on the vehicle and is lowered to engage and disengage the flywheel. The flywheel is also mounted on a shock absorber to smooth the travel of the vehicle.

A carrier type conveying apparatus capable of solving a problem in a conventional conveying apparatus wherein a conveying carriers (1) stop abnormally, comprising a rear-pushing traveling district (3) having, at its inlet, a rear-pushing drive means (5A) propelling the conveying carriers (1) at a constant speed and, at its outlet, a speed control drive means (5B) for sending out the conveying carriers (1) at the constant speed and a high-speed traveling district (4). The conveying apparatus comprises carrier connection systems (carrier connection means (9), connection engagement means (10), connection release means (11)). When the conveying carriers (1) travel in the high-speed traveling district (4), the connection of the conveying carriers (1) adjacent to each other in the longitudinal direction by the carrier connection systems is disabled. Only when the conveying carriers (1) travel in the rear-pushing traveling district (3), the conveying carriers (1) in the longitudinal direction are connected to each other by the carrier connection system to prevent the conveying carriers (1) in contact with each other at their end parts from being separated a specified distance or longer from each other.

A conveying apparatus suitable for driving a number of carriers in such a manner that the front end of each carrier thrusts the rear end of the preceding carrier is provided. The conveying apparatus comprises a guide rail and carriers. The rail includes a U-turn path section. Each carrier includes a load bar assembly including at least three load bars connected end-to-end by vertical pivot shafts in such a manner that the bars can pivot horizontally relative to each other. Each carrier also includes a load support supported by the associated middle load bar. Each carrier further includes a front trolley supporting at least the front end load bar and a rear trolley supporting at least the rear end load bar. The trolleys are supported movably on and guided by the guide rail. The trolleys are fixed to and in parallel with the end load bars. The free ends of the end load bars protrude from the front end of the front trolley and the rear end of the rear trolley so that the free end of the front end load bar of each carrier and the free end of the rear end load bar of the preceding carrier can contact together in the U-turn path section.

The present invention relates to a friction drive conveyor including carriers 1, which can be propelled along a track by frictional wheels 30 fitted along the track. Each frictional wheel 30 can be driven by a brakeless motor 29. A sensor 32 senses whether each frictional wheel 30 is in contact with any one frictional surface 15 of the carriers 1. The track includes a section along which the frictional wheels 30 are supported at regular intervals equal to or slightly shorter than the total length L of the frictional surfaces 15 on each side of each carrier 1. On the basis of a signal output from each sensor 32, a controller 24 so controls the associated brakeless motor 29 as to start rotating the associated frictional wheel 30 in contact with any one frictional surface 15 when the forward next wheel 30 gets free of the frictional surfaces 15, and as to stop driving the frictional wheel 30 having got free of the frictional surfaces 15.

Thereby, spacing between the movable bodies in the lateral travel direction can be maintained readily by using a simple structure, and the group of movable bodies can be moved laterally in such a manner that there is no mutual contact between conveyed items.
