Abstract
Abstract An apparatus for making abrasive articles, e.g., wheels, disks and the like abrasive particles wherein a train of the particles is displaced along a transport path and means is provided for automatically detecting the crystallographic orientation of the individual particles. Particles of appropriate orientation are withdrawn from the transport path and carried with fixed orientation to the wheel, disk or other substrate into which it is implanted. The individual particles are set in predetermined locations of the disk whose motion is governed by numerical control means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
An apparatus for setting an oriented particle on a substrate, said apparatus comprising means for advancing a succession of particles along a predetermined transport path; means for projecting a beam of energy affected by the orientation of the crystal lattice structure of said particles at said path for successively scanning each particle therealong; means rEsponsive to the effect of the orientation of each particle upon said beam for signaling the presence of a particle of predetermined orientation; and means for removing said particle of predetermined orientation from said path and placing said removed crystal upon said substrate with said orientation maintained.
Claim 2
Independent Claim
101 words
An apparatus for setting an oriented particle on a substrate, said apparatus comprising means for advancing a succession of particles along a predetermined transport path; means for projecting a beam of energy affected by the orientation of the crystal lattice structure of said particles at said path for successively scanning each particle therealong; means rEsponsive to the effect of the orientation of each particle upon said beam for signaling the presence of a particle of predetermined orientation; and means for removing said particle of predetermined orientation from said path and placing said removed crystal upon said substrate with said orientation maintained.
Claim 3
Dependent Claim
24 words
The apparatus defined in claim 1 wherein the means for projecting said beam includes an X-ray generator trained at a location along said path.
Claim 4
Dependent Claim
26 words
The apparatus defined in claim 2 wherein a pair of such X-ray generators train mutually orthogonal beams of X-rays at a particular point along said path.
Claim 5
Dependent Claim
32 words
The apparatus defined in claim 1 wherein said means for detecting the effect of said energy includes X-ray diffraction means responsive to the orientation of the crystal axis of the selected particle.
Claim 6
Dependent Claim
31 words
The apparatus defined in claim 1 wherein the means for displacing the selected particle from said path to said substrate includes a tube and means for generating suction in said tube.
Claim 7
Dependent Claim
23 words
The apparatus defined in claim 1, further comprising numerical control means for positioning said substrate to receive said selected one of said particles.
Claim 8
Dependent Claim
26 words
The apparatus defined in claim 6 wherein said substrate is a disk, further comprising numerical control drive means for incrementally shifting said disk radially and incrementally.
Claim 9
Dependent Claim
23 words
The apparatus defined in claim 6 wherein said numerical control means includes mechanism for shifting said substrate incrementally about two mutually perpendicular axes.
Claim 10
Dependent Claim
31 words
The apparatus defined in claim 6, further comprising a conveyer forming said transport path and dispenser means along said conveyer for feeding said particles at a substantially constant rate into same.
