Abstract
Abstract An apparatus for orientation electrically conductive bodies, preferably, non-magnetic ones, in a magnetic field, comprising an electromagnet connected with a source of alternating current, the pole pieces of this electromagnet defining therebetween a zone where the successively fed bodies are oriented, this apparatus providing for contactless separation of the successive ones of these bodies from the continuous stream in which they are fed toward the orientation zone, this apparatus further providing for selectively either grouping these successive bodies into a continuous stream, after they have passed this orientation zone, or spacing them after they have passed that zone; this invention being particularly suitable for the aims of introducing automation into such operations, when diverse objects are to be fed into all kinds of processing equipment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
An apparatus for the simultaneous contactless separation of individual non-magnetic electrically conductive bodies from a continuous flow and orientation thereof, comprising an electromagnet supplied with alternating current, pole pieces of said electromagnet defining an orientation zone widening in the direction of movement of the bodies being oriented, and means for feeding said bodies into said orientation zone and delivering said bodies therefrom in such a manner that said bodies are grouped or spaced after having passed said orientation zone, whereby separation of said bodies from said flow is achieved as a result interaction of currents induced in two adjacent bodies with an external field and also under the effect of a non-uniform magnetic field having a gradient directed toward said flow of bodies.
Claim 2
Independent Claim
123 words
An apparatus for the simultaneous contactless separation of individual non-magnetic electrically conductive bodies from a continuous flow and orientation thereof, comprising an electromagnet supplied with alternating current, pole pieces of said electromagnet defining an orientation zone widening in the direction of movement of the bodies being oriented, and means for feeding said bodies into said orientation zone and delivering said bodies therefrom in such a manner that said bodies are grouped or spaced after having passed said orientation zone, whereby separation of said bodies from said flow is achieved as a result interaction of currents induced in two adjacent bodies with an external field and also under the effect of a non-uniform magnetic field having a gradient directed toward said flow of bodies.
Claim 3
Dependent Claim
90 words
An apparatus as claimed in claim 1 wherein said pole pieces of the electromagnet are turned in the direction in which said bodies are fed at an acute angle relative to a line connecting their pointed ends, said electromagnet effecting electrodynamic braking of the flow of bodies being fed through said zone, and separating individual bodies near the pointed ends of said pole pieces in response to a non-uniform field having an opposite gradient on the side of the flow of bodies and on the side of the orientation zone.
Claim 4
Dependent Claim
38 words
An apparatus as claimed in claim 2, wherein the surfaces of said pole pieces of the electromagnet are flat, and the line in which their planes intersect extends vertically on the side from which said bodies are supplied.
Claim 5
Dependent Claim
125 words
An apparatus as claimed in claim 1, wherein said means for feeding said bodies into said orientation zone and delivering said bodies therefrom comprises at least one vibratory trough, drive means for said trough located on one side of the electromagnet, said drive means including a body conveyor having a position and rigidity of suspension for said bodies selected so as to ensure a definite advancing speed V1 at the inlet end of said orientation zone and V2 at the exit end of said orientation zone, said speeds being selected on the condition that V1 is greater than V2 when said bodies are to be grouped after having passed said orientation zone, and V2 is greater than V1 when said bodies are to be spaced.
Claim 6
Dependent Claim
100 words
An apparatus as claimed in claim 4, comprising the vibratory troughs, one on each side of said electromagnet, drive means for each of said troughs, said troughs being in proximity with each other at the point where the advancing speed of said bodies is to be changed, a smooth transfer of said bodies from one trough to the other being achieved by adapting a projection of one trough to enter a slot of the other trough having a predetermined spacing the size of which is selected to be slightly greater than the horizontal component of the amPlitude of trough vibrations.
Claim 7
Dependent Claim
170 words
An apparatus as claimed in claim 1, wherein said means for feeding said bodies into said orientation zone and delivering said bodies therefrom comprises two conveyors, one said conveyor advancing said bodies into said orientation zone at a speed V1 and the other said conveyor delivering said bodies from said orientation zone at a speed V2, the conveyor speeds being selected so that V1 is greater than V2 when said bodies are to be grouped after having passed the orientation zone and V2 is greater than V1 when said bodies are to be spaced, said conveyors being proximate at the points where the advancing speed is to be changed, said conveyors being rotatable rolls, one of the rolls of one said conveyor being smaller than the other in the zone where the conveyors are in proximity to each other and being positioned so that the upper surfaces of the conveyors be approximately on the same level, the conveyor components located in the inter-pole space being made of a non-magnetic material.
