Abstract
Abstract The present invention relates to methods for orientation of current-conducting bodies and devices for carrying into effect the methods. One of such devices comprise an electromagnet having a magnetic core including poles spaced to define an electromagnet having a magnetic core including poles spaced to define an orientation zone, a capacitor, a winding operatively associated with the core and connected in series with the capacitor, an AC supply source having a frequency corresponding to a selected relationship between the inductive and pure resistance of the bodies to be oriented and a conveyor system to move the bodies through the zone.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
77 words
A method for the orientation of current-conducting bodies having nonuniform dimensions along at least one plane passing therethrough, said method comprising generating an AC magnetic field within an orientation zone, moving the bodies to be oriented into said zone and controlling the frequency of the field in accordance with a selected relationship between the inductive and pure resistances of the bodies to be oriented and such that said bodies each have approximately equal pure and inductive resistances.
Claim 2
Independent Claim
77 words
A method for the orientation of current-conducting bodies having nonuniform dimensions along at least one plane passing therethrough, said method comprising generating an AC magnetic field within an orientation zone, moving the bodies to be oriented into said zone and controlling the frequency of the field in accordance with a selected relationship between the inductive and pure resistances of the bodies to be oriented and such that said bodies each have approximately equal pure and inductive resistances.
Claim 3
Dependent Claim
55 words
A method as claimed in claim 1 comprising generating said field in the form of a nonuniform magnetic field whose induction increases in the direction of movement of the bodies through the orientation zone to concentrate the magnetic flux at the characteristic feature of each body according to which the same is to be oriented.
Claim 4
Dependent Claim
48 words
A method as claimed in claim 1 comprising changing the direction of orientation by changing the direction of the magnetic field, each body being in an oriented position when the current induced therein has a minimum value and a magnetic moment coinciding with the direction of the field.
Claim 5
Dependent Claim
36 words
A method as claimed in claim 1 comprising changing the direction of orientation by changing the frequency and to insure the greatest current in that portion of each body according to which the same is oriented.
Claim 6
Dependent Claim
80 words
A method as claimed in claim 1 wherein the magnetic field is generated as a group of AC pulses with a duration of each group being not less than one cycle of the current of the selected frequency, an interval being provided between the groups of pulses depending upon the condition that each body to be oriented, while within the orientation zone, is to be under the effect of the magnetic flux created by at least one group of pulses.
Claim 7
Independent Claim
101 words
A device for the orientation of currEnt-conducting bodies comprising: an electromagnet including a magnetic core including poles spaced to define an orientation zone, a capacitor, a winding operatively associated with said core and connected in series with said capacitor, an AC supply source having a frequency corresponding to a selected relationship between the inductive and pure resistances of the bodies to be oriented, said winding and said capacitor forming an oscillatory circuit tuned to the frequency of said AC supply source; and a controlled key switch coupled to said source to provide a pulse supply to the winding of said electromagnet.
Claim 8
Independent Claim
101 words
A device for the orientation of currEnt-conducting bodies comprising: an electromagnet including a magnetic core including poles spaced to define an orientation zone, a capacitor, a winding operatively associated with said core and connected in series with said capacitor, an AC supply source having a frequency corresponding to a selected relationship between the inductive and pure resistances of the bodies to be oriented, said winding and said capacitor forming an oscillatory circuit tuned to the frequency of said AC supply source; and a controlled key switch coupled to said source to provide a pulse supply to the winding of said electromagnet.
Claim 9
Dependent Claim
50 words
A device as claimed in claim 6, wherein the bodies have a path of flow and the poles have the shape of pyramids having peaks located relative to said path such as to be coincident with the characteristic feature of the bodies according to which they are to be oriented.
Claim 10
Dependent Claim
34 words
A device as claimed in claim 6, wherein the magnetic core has a variable cross section smoothly decreasing toward the poles thereby concentrating the magnetic flux in the thick portion of the magnetic core.
Claim 11
Dependent Claim
53 words
A device as claimed in claim 6, wherein the poles have a shape which provides a widening of the orientation zone in a direction from the beginning toward the end of said zone thereby enabling a simultaneous orientation of the bodies and a removal thereof from said zone by the same magnetic field.
Claim 12
Dependent Claim
40 words
A device as claimed in claim 9, wherein the poles have sides which are planar facing the orientation zone and arranged vertically and/or at an angle to the vertical which is proportional to the required gradient of the magnetic field.
Claim 13
Dependent Claim
39 words
A device as claimed in claim 9, wherein the poles have sides facing the orientation zone which are surfaces of double curvature thereby enabling provision of a selected nonuniformity of the magnetic field at any point in said zone.
Claim 14
Dependent Claim
33 words
A device as claimed in claim 6, wherein the magnetic core of the electromagnet is provided with at least one pole tip including wires adjustably rearrangeable and fixable with respect to each other.
Claim 15
Dependent Claim
44 words
A device as claimed in claim 6, wherein the winding includes turns uniformly distributed along the entire core thereby improving the cooling of the winding, providing free access to the interpole space in said zone and enabling assembly from a plurality of identical magnets.
Claim 16
Dependent Claim
42 words
A device as claimed in claim 6, wherein said winding includes at least two coaxially arranged coils, in the middle and between the end faces of which orientation zones are located thereby enabling the simultaneous orientation of bodies supplied in different flows.
