Abstract: The invention relates to a roadway for dual-mode vehicles with a transition region from non-trackbound to trackbound traffic. On the roadway used as an entering roadway, the transverse guide bar on the driver's side, in the area of the transition region, is extended further into the area of the roadway, which can be used non-trackbound, than the oppositely located transverse guide bar, which is widened slightly funnel-like. The two transverse guide bars of the opposite roadway, which can be used for exiting, end at a mutually equal level. To create an adequately large transverse distance between the roadways in the area where the vehicles filter in, the roadway which can be used as an entering roadway runs with a slight bulge in the area of the transition region; moreover, this provides the possibility of a further adjoining roadway.

Abstract: On one ground rail only, a vehicle containing upper and lower bogies is rolling. The vehicle is guided from above at a ceiling rail. Each lower bogie contains a bogie wheel which is provided with lateral flanges. The ground rail includes a head profile, the upper side of which is interrupted at branch points of the rail by slots to guide the flanges of the bogie wheel. The depth of the slots is substantially less than the height of the head profile. Guide rollers, which can be lifted individually under control to determine the travel direction at the branch points, laterally engage the head profile.

Mechanism is provided for relatively longitudinally moving the load-carrying platform and the carriage between rest positions and longitudinally displaced positions. The carriage and load-carrying platform include cooperating camming rollers and cam receiving slots which upwardly guide the platform relative to the carriage as the carriage and platform are relatively longitudinally moved, to lift the load relative to the roof structure for subsequent rolling movement via the carriage on the track.

The apparatus includes a plurality of sail-driven cars connected to form a continuous chain and suspended from a monorail loop. The car suspension system has two horizontal guide wheels and one vertical carrier wheel. Substantially the entire weight of each car is carried by its vertical wheel, which is located near the car's center of gravity. Further, all three suspension wheels are located inside the monorail, thereby rendering car derailment virtually impossible.Two sails are attached to each car, one being directed upwardly and the other being directed downwardly. The surface areas of the two sails are such that the average, total current force on each sail is approximately the same. Additionally, the novel sails are free to rotate 360 degrees about their support poles, but they are biased to a preferred orientation.

Abstract: A roller guide device enabling a vehicle to be steered automatically consists of a roller retaining mechanism having a retaining lever connected to a steering linkage of a vehicle, and a pivoting lever which is pivotally connected to the forward end of the retaining lever. Arranged at the free end of the pivoting lever is a freely rotatable contact roller which can be pivoted from a retracted position in which the pivoting lever essentially coincides with the retaining lever in the direction of the pivoting shaft, into an operatively extended essentially straight-line position. The pivoting lever additionally rotates as a function of its pivoting motion about its longitudinal axis through about 90.degree., so that retraction and extension of the contact roller by pivoting through 180.degree. is achieved by a primary drive, with the contact roller concurrently rotating through 90.degree. through a secondary drive.

Abstract: A moveable target assembly includes a self-propelled carriage upon which a target is mounted for rolling movement across terrain. Axially flexible track sections are coupled together in an end to end fashion so as to define a prescribed course or path which the target will follow. The track defines a substantially planar surface and is relatively thin so that it lies flat on the surface of the terrain and thus does not present an impediment to other vehicles, infantry troops or the like that desire to traverse it. However, as the carriage is propelled along the course defined by the track, a track guide will cause successive portions of the flexible track to be initially upwardly displaced so as to perform its guiding functions yet such portions will be returned to their terrain-engaging relationship once the carriage has advanced.

Abstract: One of several inventions claimed is a method of providing increased traction to the driving wheels of a high speed transportation vehicle. The vehicle is placed within a tubular passageway, equipped with wheels arranged to contact the tube at three or more equidistant contact points, and these wheels are pressed against the inside surface of the tube by means of controlled application of powerful hydraulic pressure. Vertical stability of the vehicle is achieved by a new apparatus comprised of a spoke attached to the vehicle which projects outward to a point adjacent to but not touching the tube, a set of wheels transversely mounted on each side of the spoke, and a pair of L-shaped guide rails between which the wheels roll. An improved wind resisting braking system is claimed which uses extendable baffle plates and air ports from which compressed air is ejected in a direction opposed to the direction of travel.

Abstract: A box formed by a set of walls closed by a pivoting bottom which is openable so that the object which it carries falls vertically in the ejection zone to be collected in a receptacle. The walls are extended below the bottom so that the pivoting operation may be started before the box quite reaches the ejection zone. The bottom in the closed position forms an angle with the horizontal, thus the object which it carries is automatically jolted against the rear wall during the conveying phase. The portion of the rear wall above the rest position of the bottom is given a slight forward inclination to promote the sliding of the object towards the discharge position. A comb-shaped separation scrapes the bottom (indented) so as to loosen any object adhering abnormally thereto.
