Abstract: The invention is a system for transporting highway vehicles on railway vehicles. It has rail cars positionable relative to one another at an angle of at least about 50 degrees. Each car has a deck for highway vehicles. The system has a railroad terminal with a first track with switch(es) connected to spur(s) so trucks supporting a first set of car ends may be kept on the first track, while a second set of trucks supporting a second set of car ends is placed on the spur(s). The rail cars are thereby placed in a zig-zag configuration. For each of the rail cars, a truck supporting one end remains on the first track while a truck supporting the other end is placed on a spur. A vector parallel to the direction of travel of a truck along the tracks supporting it has a vector component of at least about 0.

Abstract: A process of reducing macrosegregation in the casting of a metal alloy ingot is disclosed. The process includes introducing a molten metal alloy into a casting mold cavity, cooling the molten metal alloy to form a solid zone, a liquid-solid mushy zone overlying the solid zone, a liquid zone overlying the liquid-solid mushy zone and a melt surface on the liquid zone, employing during the cooling at least one substantially static magnetic field having at least two planes of symmetry which intersect on the longitudinal axis of the ingot, generating the magnetic field by at least one coil means having an inner region through which the metal alloy passes, energizing the coil means by a substantially static electrical current wherein the current follows a path defined by the coil means and passes around at least one of the molten metal alloy and the zones, and dampening convection flows of the molten metal alloy which cause macrosegregation by means of the magnetic field.

Abstract: Method and apparatus for reducing macrosegregation in the simultaneous casting of a plurality of metal alloy ingots in a continuous or semicontinuous casting operation. Several casting molds are arranged closely together in an array. An outer electromagnetic coil is arranged around the outer periphery of the array of molds and their formed ingots. Preferably, when the circular molds are employed, a solenoid is provided in the central space of the molds. Direct current in the outer coil and in the solenoid create a static magnetic field whose combined effect acts on the liquid pool of the molten metal. The outer coil has straight sides and curved corners. Passive flux return devices are located along the straight sides of the outer coil. If rectangular molds are used, then only the outer electromagnetic coil is arranged around the casting assembly.
