Abstract
Abstract An animal identification and feeding apparatus having a plurality of tags, one suspended from each animal, each tag having a plurality of pockets into which either permanent magnets or non-magnetic filler strips are press fit to form a code. The code is detected by a plurality of spaced reed switches having field modifying magnets interposed between the reed switches. The tag magnets and the field modifying magnets are polarized along an axis of magnetization which is perpendicular to their interfacing surfaces and they are aligned with repelling poles facing each other.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
119 words
An identification apparatus for electronically detecting a code on one of a plurality of coded objects and comprising: (a) a plurality of spaced reed switches mounted to a support capable of receiving a coded object in a plurality of positions; (b) a coded object having a plurality of positions spaced substantially the same as the spacing of said reed switches, but of a lesser number than said plurality of said reed switches, said object having magnets mounted at selected ones of said positions for forming said code; and (c) electronic means connected to said reed switches for detecting which of said reed switches are closed when said coded object is juxtaposed to any lineal sequence of said reed switches.
Claim 2
Dependent Claim
119 words
An identification apparatus for electronically detecting a code on one of a plurality of coded objects and comprising: (a) a plurality of spaced reed switches mounted to a support capable of receiving a coded object in a plurality of positions; (b) a coded object having a plurality of positions spaced substantially the same as the spacing of said reed switches, but of a lesser number than said plurality of said reed switches, said object having magnets mounted at selected ones of said positions for forming said code; and (c) electronic means connected to said reed switches for detecting which of said reed switches are closed when said coded object is juxtaposed to any lineal sequence of said reed switches.
Claim 3
Dependent Claim
39 words
An apparatus in accordance with claim 1 wherein said reed switches are spaced along a surface and are oriented with their reeds substantially perpendicular to said surface and wherein said magnets are permanent magnets polarized perpendicularly to said surface.
Claim 4
Dependent Claim
30 words
An apparatus in accordance with claim 2 wherein the lead from the end of the reed switch closest to said surface is bent at approximately right angles to said reeds.
Claim 5
Dependent Claim
71 words
An apparatus in accordance with claim 2 wherein the magnets of said coded object are polarized with like poles facing in the same direction and wherein a plurality of field modifying magnets are interposed between said reed switches along said surface, said field modifying magnets being polarized perpendicularly to said surface and positioned to have all like poles of said field modifying magnets interfacing identically like poles of said object magnets.
Claim 6
Dependent Claim
115 words
An animal identification and feeding apparatus comprising: (a) an electrically actuable feeder; (b) a plurality of magnetically actuable switches spaced along a surface adjacent a feeder; (c) a tag attached to each of a plurality of animals to be fed, each tag having a plurality of positions spaced substantially the same as the spacing of said switches, but of a lesser number than said plurality of said switches, each of said tags having permanent magnets mounted at selected ones of said positions; and (d) electronic computer means connected to said switches and to said feeder for detecting which of said switches are actuated and for actuating said feeder in response to said detected code word.
Claim 7
Dependent Claim
115 words
An animal identification and feeding apparatus comprising: (a) an electrically actuable feeder; (b) a plurality of magnetically actuable switches spaced along a surface adjacent a feeder; (c) a tag attached to each of a plurality of animals to be fed, each tag having a plurality of positions spaced substantially the same as the spacing of said switches, but of a lesser number than said plurality of said switches, each of said tags having permanent magnets mounted at selected ones of said positions; and (d) electronic computer means connected to said switches and to said feeder for detecting which of said switches are actuated and for actuating said feeder in response to said detected code word.
Claim 8
Dependent Claim
13 words
An apparatus in accordance with claim 5 wherein said switches are reed switches.
Claim 9
Dependent Claim
39 words
An apparatus in accordance with claim 6 wherein said reed switches are spaced along a surface and are oriented with their reeds substantially perpendicular to said surface and wherein said magnets are permanent magnets polarized perpendicularly to said surface.
Claim 10
Dependent Claim
30 words
An apparatus in accordance with claim 7 wherein the lead from the end of the reed switch closest to said surface is bent at approximately right angles to said reeds.
Claim 11
Dependent Claim
71 words
An apparatus in accordance with claim 7 wherein the magnets of said coded object are polarized with like poles facing in the same direction and wherein a plurality of field modifying magnets are interposed between said reed switches along said surface, said field modifying magnets being polarized perpendicularly to said surface and positioned to have all like poles of said field modifying magnets interfacing identically like poles of said object magnets.
Claim 12
Dependent Claim
37 words
An apparatus in accordance with claim 5 wherein each of said tags have a pocket formed into a surface of the tag, some of said pockets having magnets inserted therein and other having non-magnetic material inserted therein.
Claim 13
Dependent Claim
34 words
An apparatus in accordance with claim 10 wherein the distally spaced pockets of each of said tags has a magnet inserted therein with its outwardly facing surface recessed from said surface of the tag.
Claim 14
Dependent Claim
40 words
An apparatus in accordance with claim 10 wherein the distally spaced pockets have a magnet inserted in each which applies a magnetic field to said magnetically actuable switches which is less than the field applied by the other tag magnets.
