Abstract
Abstract A machine for locating reed relay contact elements in holes in an operable trough which opens to allow the reed elements to drop out of it comprises magnets mounted for rotation below the trough so that the reed elements rotate under the influence of the magnetic field from the magnets and thereby locate in the holes in the trough. A further rotating magnet structure is mounted over the magnets and above the trough to remove, on movement of the trough between it and the magnets, any reed elements that are not located in holes in the trough.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
34 words
A method of locating elongate magnetic elements in holes or recesses comprising subjecting the elements to a rotating magnetic field whereby said elements are constrained to rotate and locate in said holes or recesses.
Claim 2
Independent Claim
34 words
A method of locating elongate magnetic elements in holes or recesses comprising subjecting the elements to a rotating magnetic field whereby said elements are constrained to rotate and locate in said holes or recesses.
Claim 3
Dependent Claim
47 words
Apparatus for carrying out the method of claim 1, comprising a trough, element locating means in the bottom of the trough and means for providing a rotating magnetic field in the region of the trough for rotating in use of the apparatus elements placed in the trough.
Claim 4
Dependent Claim
38 words
Apparatus as claimed in claim 2, wherein collector means are provided for removing from the trough any magnetic elements that are not located in the locating means of the trough as a consequence of the rotating magnetic field.
Claim 5
Dependent Claim
22 words
Apparatus as claimed in claim 3, wherein the collector means comprises a drum positioned above the trough containing a rotating magnet arrangement.
Claim 6
Dependent Claim
30 words
Apparatus as claimed in claim 2 wherein the rotating magnetic field for orientation of the elements is generated by means of permanent magnets mounted closely adjacent and beneath the trough.
Claim 7
Dependent Claim
22 words
Apparatus as claimed in claim 2, wherein the said locating means comprises holes or recesses extending through the bottom of the trough.
Claim 8
Dependent Claim
44 words
Apparatus as claimed in claim 6, wherein the trough is of split configuration and arranged so that it opens along the bottom thereof thereby to enable elements located in the holes or recesses to be released to fall through the bottom of the trough.
Claim 9
Dependent Claim
26 words
Apparatus as claimed in claim 7, wherein the trough is of V-shape cross section and the sides thereof are inclined at an angle of approximately 120*.
Claim 10
Dependent Claim
34 words
Apparatus as claimed in claim 2, wherein the trough is mounted on a conveyor and in use of the apparatus is traversed in the direction of its longitudinal axis through the rotating magnetic field.
Claim 11
Dependent Claim
89 words
Apparatus for locating magnetic reeds or similar elongate magnetic elements in holes or recesses comprising a trough of generally V-shaped cross section, element locating means having defined therein holes or recesses for receiving said reeds or said elements said locating means being provided in the root of the generally V-shaped trough, and rotating magnetic field producing means positioned in the region of the trough for providing a magnetic field rotatable for constraining the said reeds or elements to rotate and to be located in the said holes or recesses.
Claim 12
Dependent Claim
89 words
Apparatus for locating magnetic reeds or similar elongate magnetic elements in holes or recesses comprising a trough of generally V-shaped cross section, element locating means having defined therein holes or recesses for receiving said reeds or said elements said locating means being provided in the root of the generally V-shaped trough, and rotating magnetic field producing means positioned in the region of the trough for providing a magnetic field rotatable for constraining the said reeds or elements to rotate and to be located in the said holes or recesses.
