Abstract
Abstract Apparatus for selecting one or all similar cards from a plurality of randomly distributed and different cards, the cards having magnetizable tags along an edge, in which there is a plurality of magnets which can be selectively and independently energized and deenergized. There are means for moving the cards into contact with the magnets so that ones with tags corresponding to the energized magnets are held by those magnets and those which do not have corresponding tags can be moved from the magnets. In this way selected cards, regardless of their positions in a stack of cards can be separated from nonselected cards.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
130 words
For use in selecting cards from a plurality of randomly distributed cards which have magnetizeable portions at fixed positions along an edge and which are distinguished from each other by the numbers and locations of the portions, apparatus comprising a compartment for the cards, a plurality of magnets extending across the compartmenT and, when the cards are located in the compartment, across said edge of each card, said magnets being selectively operable to attract and not to attract the magnetizeable portions on the cards, a support for said cards, said support and said magnets being relatively movable between positions in which said edge of the cards contact the magnets and in which said edge is spaced from the magnets, thus by making that movement to separate selected and nonselected cards.
Claim 2
Dependent Claim
130 words
For use in selecting cards from a plurality of randomly distributed cards which have magnetizeable portions at fixed positions along an edge and which are distinguished from each other by the numbers and locations of the portions, apparatus comprising a compartment for the cards, a plurality of magnets extending across the compartmenT and, when the cards are located in the compartment, across said edge of each card, said magnets being selectively operable to attract and not to attract the magnetizeable portions on the cards, a support for said cards, said support and said magnets being relatively movable between positions in which said edge of the cards contact the magnets and in which said edge is spaced from the magnets, thus by making that movement to separate selected and nonselected cards.
Claim 3
Dependent Claim
21 words
Apparatus as claimed in claim 1 in which said magnets are permanent magnets and are selectively movable relatively to said support.
Claim 4
Dependent Claim
17 words
Apparatus as claimed in claim 1 in which said magnets are electromagnets and selectively energized and deenergized.
Claim 5
Dependent Claim
39 words
Apparatus as claimed in claim 3 in which said support comprises a platform forming the base of the compartment and the magnets extend across the top of the compartment, said platform being movable towards and away from said magnets.
Claim 6
Dependent Claim
35 words
Apparatus as claimed in claim 4 in which said nonselected and selected cards are held and not held by the magnets respectively and said selected cards are movable with the platform away from said magnets.
Claim 7
Dependent Claim
23 words
Apparatus as claimed in claim 5 in which means is provided for displacing said selected cards from said lowered position of said platform.
Claim 8
Dependent Claim
26 words
Apparatus as claimed in claim 6 in which said means comprises a pusher element movable between the lower edges of the nonselected cards and the platform.
Claim 9
Dependent Claim
42 words
For use in the apparatus as claimed in claim 3, an electromagnet comprising a comblike core having a spine and a plurality of teeth projecting from that spine and spaced apart along said spine and electrical windings on each of said teeth.
Claim 10
Dependent Claim
55 words
For use in the apparatus as claimed in claim 3 an electromagnet comprising a comblike core having a spine and a plurality of teeth projecting from that spine and spaced apart along said spine and electrical windings on each of said teeth, wherein said teeth are enclosed within a U-shaped channel member of magnetizeable material.
Claim 11
Dependent Claim
44 words
Apparatus as claimed in claim 1 in which the magnets comprise fixed permanent magnets having electric coils associated therewith said coils being selectively actuated to modify the field of the permanent magnets to attract or not to attract the magnetizable portions on the cards.
Claim 12
Dependent Claim
19 words
Apparatus as claimed in claim 1 including means for forming said magnetizeable portions along said edges of said cards.
Claim 13
Dependent Claim
74 words
Apparatus as claimed in claim 1 including means for forming magnetizeable portions along an edge of a card having a magnetizeable strip along that edge which comprises means for locating a card in a fixed position relative to a plurality of independently and selectively operable knives so that said strip is below said knives, and means operating said knives selectively to remove sections of said strip and leave magnetizeable portions between said removed sections.
Claim 14
Dependent Claim
31 words
For use in conjunction with the apparatus as claimed in claim 1, a card of laminated material and a metallic strip set in one edge of said card between said laminations.
Claim 15
Dependent Claim
40 words
Apparatus as claimed in claim 13 in which said metallic strip is slit from its edge spaced from the card transversely of the strip towards said cards so that portions between said slits can be removed by a longitudinal cut.
Claim 16
Dependent Claim
44 words
For use in apparatus as claimed in claim 1, a set of cards comprising magnetizeable portions along an edge of each card, each card in the set being distinguished from the remainder by the numbers and locations of said magnetizeable portions along said edge.
Claim 17
Dependent Claim
118 words
For use in selecting cards from a plurality of randomly distributed cards having magnetizeable portions fixed along an edge thereof and which are distinguished from each other by the numbers and locations of those portions, apparatus comprising a compartment for said cards, a plurality of electromagnets extending across the compartment and across said edge of each card when said cards are located in saiD compartment, said magnets being selectively energized and deenergized to attract and not to attract the magnetizeable portions of the cards, and means for moving said cards into contact and out of contact with said magnets thus to separate cards having portions corresponding to the selected energized and deenergized magnets from cards not so corresponding.
Claim 18
Dependent Claim
118 words
For use in selecting cards from a plurality of randomly distributed cards having magnetizeable portions fixed along an edge thereof and which are distinguished from each other by the numbers and locations of those portions, apparatus comprising a compartment for said cards, a plurality of electromagnets extending across the compartment and across said edge of each card when said cards are located in saiD compartment, said magnets being selectively energized and deenergized to attract and not to attract the magnetizeable portions of the cards, and means for moving said cards into contact and out of contact with said magnets thus to separate cards having portions corresponding to the selected energized and deenergized magnets from cards not so corresponding.
Claim 19
Dependent Claim
19 words
Apparatus as claimed in claim 16 including means for forming said magnetizeable portions along said edges of said cards.
Claim 20
Dependent Claim
74 words
Apparatus as claimed in claim 16 including means for forming magnetizeable portions along an edge of a card having a magnetizeable strip along that edge which comprises means for locating a card in a fixed position relative to a plurality of independently and selectively operable knives so that said strip is below said knives, and means operating said knives selectively to remove sections of said strip and leave magnetizeable portions between said removed sections.
