Abstract
Abstract A method of orienting electrically conductive bodies, preferably, non-magnetic ones, in a magnetic field and apparatus for performing such method, wherein a body is oriented under the action thereupon of a non-uniform magnetic field induced by an alternating electric current, by means of electromagnets connected to an alternating current supply, the pole pieces of these magnets defining therebetween an orientation zone, whereby a body can be oriented both from an arbitrary position and from any intermediate position into a predetermined final spatial position, with the final oriented position of the body being retained.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
137 words
An apparatus for orienting electrically conductive bodies, said apparatus comprising an electromagnetic including magnetic core means including a plurality of generally C-shaped magnetic core members cooperatively defining an orientation zone, said electromagnet also comprising winding means adapted to be connected to an alternating electric current source, a pair of pole pieces, all of Said plurality of magnetic core members being associated with said pair of pole pieces, a first one of said pole pieces being disposed above a second one of said pole pieces, said first pole piece provided with at least one passage extending therethrough, through which a body can be introduced into said orientation zone to be oriented therein, said second pole piece being provided with at least one passage extending therethrough, through which said body can leave said orientation zone after the orientation operation.
Claim 2
Independent Claim
137 words
An apparatus for orienting electrically conductive bodies, said apparatus comprising an electromagnetic including magnetic core means including a plurality of generally C-shaped magnetic core members cooperatively defining an orientation zone, said electromagnet also comprising winding means adapted to be connected to an alternating electric current source, a pair of pole pieces, all of Said plurality of magnetic core members being associated with said pair of pole pieces, a first one of said pole pieces being disposed above a second one of said pole pieces, said first pole piece provided with at least one passage extending therethrough, through which a body can be introduced into said orientation zone to be oriented therein, said second pole piece being provided with at least one passage extending therethrough, through which said body can leave said orientation zone after the orientation operation.
Claim 3
Dependent Claim
59 words
An apparatus, as set forth in claim 1, wherein said magnetic core means including said plurality of generally C-shaped magnetic core members is associated with a plurality of pole pieces, said magnetic core means being of a multi-level structure, with a respective one of said plurality of pole pieces being disposed at each level of said magnetic core means.
Claim 4
Dependent Claim
62 words
An apparatus, as set forth in claim 1, wherein each of said pole pieces is shaped as a truncated pyramid having a smaller base and a greater base, the smaller bases facing each other, the cross-sectional shape of each said passage through which said body can leave the respective orientation zone corresponding to the contour of said body in a plan view.
