Abstract: What is proposed is a method of assembling nonmagnetic current-conducting components into units along an axis of assembly. The assembly is arranged under the effect of electrodynamic forces formed by the interaction of a primary alternating magnetic field directed along the axis of assembly and a secondary magnetic field. The components to be assembled are placed in the primary magnetic field so that the areas covered by the contours of the currents induced in these components by the magnetic field are located in planes approximately perpendicular to the axis of assembly; and in each adjacent pair of components to be assembled the regions covered by the contours of the induced currents at least partially overlap each other.

Abstract: A device for arranging ferromagnetic components a preset distance from one another including an electromagnet defining a pole gap wherein a nonuniform attractive magnetic field is formed with a gradient directed along its axis of symmetry. At least one of the pole pieces of the electromagnet is provided with a ferromagnetic rack adapted to move in the plane in which it lies. The plane of the rack is substantially normal to the direction of the magnetic field gradient. The rack includes teeth which are spaced apart in accordance with a desired preset distances between ferromagnetic componets. The device also comprises a means for feeding ferromagnetic components into the magnetic field, in the direction of its gradient.

Abstract: A device for making sets of nonmagnetic current-conducting components on a base component in arrangements constituting identification patterns of the set being made. The device comprises a source of an alternating magnetic field, feeding the components arranged into a set as well as the base components into the working area of the magnetic field, and extractor means for removing the complete sets of components from the working area of the magnetic field. Each base component is a substrate comprising essentially a dielectric plate, fitted with inserts made from a current-conducting material and having cross section configurations similar to the cross-sectional shapes of the components being arranged into a set. The inserts arranged to determine the identification patterns of the set being made.

Abstract: A method of dismantling units made up of current-carrying parts assembled with an interference or according to the sliding or running fit. The method consists in placing the units in an alternating magnetic field and orienting them so as to withdraw the parts in the course of dismantling in the direction perpendicular to the induction vector of the field.The vibration frequency and induction intensity of the field should be sufficient to build up forces which are stronger than the forces of cohesion between the parts in a unit.
