Abstract: Linear electric motors suitable for transportation of one or more vehicles along a road which may be a railroad, having electric coils as powerable motor parts and either nonferous metal plates, superconducting magnets or shorted coils as passive motor parts; employing a pulsating power source for powered motor parts, which power may be of constant or varying frequency; and having motor part spacing, and a space time relationship of motor part spacing and timing of said power source operation so as to require a minimum number of road parts per mile, and so as to provide continuous power transmission for propulsion and braking of said vehicles.

Abstract: An improved linear motor utilizes two circuits, rather that one circuit and an opposed plate, to gain efficiency. The powered circuit is a flat conductive coil. The opposed segmented rail circuit is either a plurality of similar conductive coils that are shorted, or a plurality of ladders formed of opposed conductive bars connected by a plurality of spaced conductors. In each embodiment, the conductors are preferably cables formed from a plurality of intertwined insulated wires to carry current evenly.

Abstract: Apparatus for the interface of an elevated vertical roadway and vehicle wheel, for achieving greater traction than possible using vehicle weight, and for minimizing vehicle wheel oscillation against the roadway, for minimizing roadway damage associated with heavy vehicle motion, said apparatus having a roadway/wheel interface geometry comprising a substantially vertical roadway with substantially vertical but concave sides, and convex wheel rims rolling on said convex roadway sides, with wheel rim width which is equal to or less than the width of the concave part of the roadway side; and said apparatus having a compression apparatus, independent of vehicle weight, for causing the wheels to be in substantial compression against the side of the roadway, in one said embodiment said compression apparatus being formed by the combination of pairs of parallel wheel axles on opposite sides of the roadway, and cables wound in substantial tension around each said pair of axles, said tensioned cables urging said axles t

Abstract: A segmented rail linear induction motor has a segmented rail consisting of a plurality of nonferrous electrically conductive segments aligned along a guideway. The motor further includes a carriage including at least one pair of opposed coils fastened to the carriage for moving the carriage. A power source applies an electric current to the coils to induce currents in the conductive surfaces to repel the coils from adjacent edges of the conductive surfaces.

Abstract: An electromagnetic cylindrical projectile mass launcher and a method of operation is provided which includes a cylindrical projectile having a conducting armature, a cylindrical barrel in which the armature is received, a plurality of electromagnetic drive coil stages, a plurality of pulse energy sources, and a pulsed power arrangement for generating magnetic pulses forming a pulsed magnetic wave along the length of the launcher barrel. The pulsed magnetic wave provides a propelling force on the projectile along the drive coil. The pulsed magnetic wave of the drive coil stages is advanced along the armature faster than the projectile to thereby generate an induced current wave in the armature. The pulsed generation of the magnetic wave minimizes electromagnetic heating of the projectile and provides for smooth acceleration of the projectile through the barrel of the launcher.
