Electrodynamic separation of nonmagnetic free-flowing materials is accomplished by feeding the flow of a material into a region of maximum intensity of a variable nonuniform magnetic field for inducing maximum eddy currents in electrically conducting particles of the material being separated and producing maximum electromagnetic forces which deflect the electrically conducting particles from the direction of feed of the material being separated. The variable nonuniform magnetic field is generated by an electromagnet having a closed magnetic core with a magnetic air gap defined by pole pieces. The electromagnet pole pieces are symmetrically divergent from the pole axes in a plane substantially perpendicular to the direction of feed of the material being separated.

Method of and apparatus for electrodynamic separation of nonmagnetic

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.

Method of assembly of nonmagnetic current-conducting components

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.

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.

A device for contactless separation of individual ferromagnetic components from a flow of components, comprising a magnet and guards arranged between pole pieces. The guards are made from a non-magnetic material and confine a channel through which components are fed. The gap between the pole pieces is made narrowing in the direction of the component flow. The cross section of at least one pole piece is selected such as to ensure saturation of the magnetic material from which this pole piece is made, when a component being separated from the flow is in the narrowest portion of the pole gap.

Device for contactless separation of individual ferromagnetic components

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.

Method of dismantling units

A method of oriented feeding of nonmagnetic current-conducting components is proposed, wherein an alternating magnetic field is set up, whose induction vector is normal to the desired direction of feeding. Components are introduced into this field, one by one, and at least one closed current-conducting loop is secured in the magnetic field so that its plane is normal to the induction vector of the field and offset with respect to the geometrical center of the component introduced into the field in the direction of feeding. Oriented feeding is effected under the action of electrodynamic forces induced in the alternating magnetic field as a result of the interaction of the overlapping current circuits induced by the magnetic field in the components and in the current-conducting closed loop. The device for carrying out the proposed method comprises a source of an alternating magnetic field and a sectional plate arranged in the working area of this field, each plate section including an electric coil. The device is also provided with a control panel including a set of contacts corresponding in number to and arranged in the same manner as the plate sections. Each coil has one of its terminals connected to a respective control panel contact, and the other coil terminal is grounded.
