Abstract: An electromagnetic energization system is disclosed wherein a stray alternating magnetic field is generated by conducting a current through a discrete (i.e., indefinite) length of wire or rod instead of a fine wire winding. A permanent magnet rotor is disposed so that it intersects the stray field in an appropriate manner to effect rotation of the rotor, which rotation is usable to energize or propel an object located in the vicinity of the conductor. The conductor, usable with toy vehicles and multiple track segments, is of single continuous length or is series connectable by means of quick disconnect electrical connectors. The permanent magnet rotor can be incorporated in a planetary gear system to achieve speed reduction between the spinning rotor and a drive mechanism for a mobile object.

Abstract: A conveyor apparatus in which magnetic liquid is provided between a transfer track and a transfer object and a permanent magnet is fitted on the bottom of the transfer object to attract the magnetic liquid to move together with the transfer object thereby serving as a lubricant and permits the transfer object to move on the track afloat or buoyed-up by the magnetic liquid. An edge of a magnetic pole is shaped to have a loft angle in contact with the magnetic liquid to produce an upward component during its movement thereby increasing buoyancy and stability of the transfer object. Dust stir-up is precluded by virtue of the use of a magnetic liquid, as opposed to a conventional pressurized air support method.

Abstract: Air flow guide members at each end of the cargo carrying structure of an open top gondola type railway car, together with rounded transition or corner surfaces on the exterior of the car and aerodynamically shaped and oriented cross braces within the car serve to reduce aerodynamic drag on the car as it is moved. Additionally, to further enhance the energy efficiency of the car, the cargo carrying structure is formed predominantly of a light weight weldable metal, such as an aluminum alloy, and the side support members are placed on the interior wall of each side to provide a smooth, minimized air flow resistant side surface.

Abstract: A cable assembly is described, for safely connecting an electrical power source such as an electrical outlet at an airport, to a power consuming device such as an aircraft. The assembly includes an electrical cable (18) with a connector (16) at one end for engaging the receptacle on an aircraft to supply power thereto, and a relay (30) at the inner end of the cable which can connect and disconnect a power source to the cable. "On" and "off" power switches (32, 34) are located near the outer end of the cable. The "on" switch enables a workman to operate the remote relay to turn on the power immediately after he has connected the outer end of the cable to the power consuming device. This encourages the workman to apply a voltage to the cable only after the connection is made, to avoid sparks that might ignite flammable fumes.

Abstract: A railroad track including rails and transversely extending ties. The end portions of the ties are placed on a rigid substructure. For reducing the sound emission, loading members are placed on the ties between the rails. These loading members have an essentially T-shaped cross-section, wherein the horizontally projecting portions are placed on adjacent ties. Sound-insulating elastic inserts may be provided between the ties and the loading members. Consequently, no fittings for fastening the loading members are required. In addition, the space existing between the ties is utilized in an optimum manner by filling it with sound-insulating material.

Abstract: According to the invention there is provided a railway sleeper having a formed inverted channel-shaped section the ends of which have their upper surfaces downwardly inclined and shaped in a corrugated fashion to add strength and rigidity to said ends.The `dished spade` end contour of the sleeper may be pressed from a standard rolled steel channel section. By virtue of the stronger ends thus produced these portions can sustain a greater load than the conventional design hitherto--this means that the length of the sleeper according to this invention may be much shorter, e.g. 20% less than the conventional design for the same load bearing capacity, representing a considerable cost savings. The shape facilitates stacking, and lateral insertion beneath the track for track maintenance and replacement etc.

Abstract: Members are provided for securing together a pair of freight containers having corner fittings which abut one another, the abutting walls of the corner fittings each having formed therein aligned, elongate apertures. The members comprise an elongate locking member in the opposed sidewalls of which are formed opposed grooves each of generally tapering configuration. On passage of the locking member through the aligned apertures to bring the grooves into axial alignment with the abutting walls, and on subsequent rotation of the locking member about its central longitudinal axis, the edge regions of the walls bounding the apertures are received within the grooves to be urged into locking engagement with one another by the sidewalls of the grooves.

Abstract: A pair of coplanar, telescopic tracks are held in a spaced-apart and generally parallel relationship by a plurality of crossties. The crossties may also be telescopic to vary the space between the tracks according to use. At one end the tracks can be elevated by length-adjustable props or variable trusses. Each track comprises at least two segments, a first segment adapted to be slidably disposed in a channel of the second segment. The segments can be channel bars. A detent is used to temporarily hold the tracks at any of a plurality of telescoped lengths. A variable truss comprises a pair of divergent struts with a variable length member subtending the angle between the struts. This device is especially useful as a variable ramp for wheelchairs when it is made from relatively lightweight material such as aluminum.

Abstract: An amusement ride system according to the present invention comprises a pair of rails extending at a fixed distance from each other, and a passenger car located between the rails and traveling along the rails. A plurality of wheel units are provided on either side portion of the car, along the rails. Each wheel unit includes a set of wheels, which are in rolling contact with each corresponding rail, so as to hold it between them. The middle portion of the rail pair is twisted around a central axis between the rails, thus forming at least one twist region. As the car runs past the twist region of the rails, therefore, it is rotated around the central axis, following the twist of the rails.

Abstract: A ski comprising a guide pipe (2) guiding a string of elements that transmit a towing force to any conventional towing device attached to the string at suitable intervals. Instead of being a tension element like a wire, a rope or the like, which is conventional in known ski tows, the string consists of separate pressure elements (7), each having at either end an end face contacting the opposed end face of an adjacent element, whereby the towing force is transmitted by pushing the string, which is accordingly subjected to a compression force.
