Abstract: Apparatus for propelling, suspending and guiding a conveyance across ground without contact between said conveyance and said ground, comprising an electromagnetic, air cored induction motor including a primary formed of a coaxial array of coils; means for energizing said coils with polyphase electrical alternating currents to create an electromagnetic wave traveling longitudinally along the array; a secondary formed of a sleeve concentric to and surrounding said array of coils and made of conducting material, said sleeve being electromagnetically coupled to said primary and being cut along a longitudinal generatrix thereof to define a slot permitting the support means which supports the primary to pass there through.

Abstract: A method by which particle separation is accomplished by taking advantage of the large difference in the diffusion rates between the ionized and neutral components of a gaseous mixture, in the presence of a magnetic field. Means for separating isotopes in a continuous and commercially successful manner. Apparatus in which the desired component is selectively ionized, accelerated and guided by a magnetic field along a predetermined axis, while the neutral particles are transversely removed by means of vacuum or cryogenic pumps.
