Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 129 words
A categorical indicator device on an article display rack, said display rack including a plurality of rows for display of articles, said articles, discretely stackable on said shelves in columns, said shelves slanted downward for gravity feed of said articles, said categorical indicator device adapted to optionally indicate at least one subset of a category matrix of articles, said indicator device comprising indicator means including members having a one-to-one physical relationship with individual members of said category matrix at said columns, storage means for storing the identity of said at least one category subset, selection means for selecting a selected subset of said at least one subset, and control means for energizing selected indicator members associated with said selected subset whereby said selected subset is distinguished from other articles.
Claim 2
Dependent Claim 129 words
A categorical indicator device on an article display rack, said display rack including a plurality of rows for display of articles, said articles, discretely stackable on said shelves in columns, said shelves slanted downward for gravity feed of said articles, said categorical indicator device adapted to optionally indicate at least one subset of a category matrix of articles, said indicator device comprising indicator means including members having a one-to-one physical relationship with individual members of said category matrix at said columns, storage means for storing the identity of said at least one category subset, selection means for selecting a selected subset of said at least one subset, and control means for energizing selected indicator members associated with said selected subset whereby said selected subset is distinguished from other articles.
Claim 3
Dependent Claim 22 words
The invention of claim 1 wherein said indicator means comprises illuminable electric lamps in physical relationship to said articles in said columns.
Claim 4
Dependent Claim 18 words

Claim 8
Dependent Claim 42 words
The apparatus of claim 6 wherein said control means comprises circulating register means for receiving and storing a predetermined digital pattern from said digital processor and for energizing and de-energizing specific ones of said indicator members according to said predetermined digital pattern.
Claim 9
Dependent Claim 63 words
The apparatus of claim 1 including a plurality of indicator members in a row, said storage device containing means for independently energizing at least first and second subsets of said category matrix, said first and second subsets containing at least one common member, and at least first and second command buttons operable to command energization of said first and second subset indicator members.
