Abstract
Abstract Apparatus and method for performing manufacturing operations on an article of manufacture, e.g., for producing and placing formed pieces of insulation into nonradially aligned or otherwise irregularly oriented slots of a magnetic core. Preferred form of apparatus includes compensating means for selectively positioning an article support relative to a datum plane of the apparatus. This means, in one form, includes a first drive member that tends to drive a driven member through a fixed angular increment. The driven member is movable about a preselected movable reference point which in turn is movable differential amounts relative to the pitch or drive line of the first drive member so that the driven member is selectively movable through a preselected net differential increment of travel relative to a fixed increment of travel of the first drive member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
Apparatus for performing predetermined manufacturing operations on an article of manufacture having a plurality of openings therein, the apparatus comprising: position determining control means for moving the article of manufacture relative to a datum plane of the apparatus and for sequentially aligning the openings with the datum plane as predetermined manufacturing operations are being performed thereon, said control means including an article holding assembly mounted for selective movement toward and away from the apparatus datum plane and for selective angular displacement relative to an axis generally parallel to the apparatus datum plane such that the article of manufacture is moved to sequentially align the openings therein with the apparatus datum plane as individual predetermined manufacturing operations are performed on the article of manufacture.
Claim 2
Dependent Claim
123 words
Apparatus for performing predetermined manufacturing operations on an article of manufacture having a plurality of openings therein, the apparatus comprising: position determining control means for moving the article of manufacture relative to a datum plane of the apparatus and for sequentially aligning the openings with the datum plane as predetermined manufacturing operations are being performed thereon, said control means including an article holding assembly mounted for selective movement toward and away from the apparatus datum plane and for selective angular displacement relative to an axis generally parallel to the apparatus datum plane such that the article of manufacture is moved to sequentially align the openings therein with the apparatus datum plane as individual predetermined manufacturing operations are performed on the article of manufacture.
Claim 3
Dependent Claim
51 words
The apparatus of claim 1 wherein the apparatus further comprises material placing means for moving material generally toward the article holding assembly; said material placing means including a tool movable into alignment with the apparatus datum plane during selective movement of the article holding assembly relative to the apparatus datum plane.
Claim 4
Dependent Claim
31 words
The apparatus of claim 2 further including a frame; and wherein the article holding assembly includes a mandrel that is supported for rotation and generally rectilinear movement relative to the frame.
Claim 5
Dependent Claim
146 words
Apparatus for performing manufacturing operations on an article of manufacture comprising a magnetic core for use in an inductive device, the magnetic core having at least one preselected nonradially disposed slot in a portion thereof; the apparatus comprising: position determining control means foR disposing the portion of the core having the at least one nonradially disposed slot therein in alignment with a datum plane of the apparatus, said position determining control means including a locating device for angularly moving the core about an axis and for shifting the core axis from one position to another relative to the datum plane of the apparatus to effect alignment of the portion of the core having the at least one nonradially disposed slot therein with the datum plane of the apparatus; and means movable relative to the magnetic core for performing a manufacturing operation on the article of manufacture.
Claim 6
Dependent Claim
146 words
Apparatus for performing manufacturing operations on an article of manufacture comprising a magnetic core for use in an inductive device, the magnetic core having at least one preselected nonradially disposed slot in a portion thereof; the apparatus comprising: position determining control means foR disposing the portion of the core having the at least one nonradially disposed slot therein in alignment with a datum plane of the apparatus, said position determining control means including a locating device for angularly moving the core about an axis and for shifting the core axis from one position to another relative to the datum plane of the apparatus to effect alignment of the portion of the core having the at least one nonradially disposed slot therein with the datum plane of the apparatus; and means movable relative to the magnetic core for performing a manufacturing operation on the article of manufacture.
Claim 7
Dependent Claim
33 words
The apparatus of claim 4 further including a member for supporting a magnetic core; and wherein the locating means includes cam means for moving the member for supporting relative to the datum plane.
Claim 8
Independent Claim
165 words
A method of performing a manufacturing operation on an article of manufacture that comprises a magnetic core having slots disposed therein, the method comprising the steps of: supporting the article of manufacture on a holder having a central axis located in one position; performing a first work operation by moving a tool along a given predetermined path and adjacent to a first preselected portion of the article of manufacture; aligning a second preselected portion of the article of manufacture with the predermined path by angularly displacing the holder having the core thereon through a preselected angle about the central axis thereof and shifting the central axis a predetermined distance to another position, displaced from the one position, to establish the desired alignment of the predetermined path of travel and the second preselected portion of the article of manufacture; and performing a second work operation by moving a tool along the given predetermined path and adjacent to the second preselected portion of the article of manufacture.
Claim 9
Independent Claim
165 words
A method of performing a manufacturing operation on an article of manufacture that comprises a magnetic core having slots disposed therein, the method comprising the steps of: supporting the article of manufacture on a holder having a central axis located in one position; performing a first work operation by moving a tool along a given predetermined path and adjacent to a first preselected portion of the article of manufacture; aligning a second preselected portion of the article of manufacture with the predermined path by angularly displacing the holder having the core thereon through a preselected angle about the central axis thereof and shifting the central axis a predetermined distance to another position, displaced from the one position, to establish the desired alignment of the predetermined path of travel and the second preselected portion of the article of manufacture; and performing a second work operation by moving a tool along the given predetermined path and adjacent to the second preselected portion of the article of manufacture.
Claim 10
Dependent Claim
42 words
The method of claim 6 including aligning a third portion of the article with the given predetermined path and performing at third work operation by moving a tool along the predetermined path and adjacent to the third preselected portion of the article.
Claim 11
Dependent Claim
32 words
The method of claim 7 wherein the first, second, and third work operations comprise performing substantially the same work operation on, respectively, first, second, and third portions of the article of manufacture.
