Abstract
Abstract Graphic information contained in coordinated arrays is released a bit at a time by the use of an information isolating device. When an instruction mark on the device is located next to a bit of information in one array, a retrieval mark will be located next to a coordinated bit of information in another array. An endless belt or a metal clip at least in part transparent is placed about a leaf or collection of leaves containing graphic information and is moved to isolate the information.

A device for selectively isolating information contained on information bearing material, said material being a collection of leaves, comprising: a band placed about the material said band having both opaque and transparent section means for selectively blocking out some information and displaying other information on the material, said band being freely movable about the face of the material, the leaves of the material being bound together and the binding being such that the leaves can be fully folded back upon themselves, the information on the top leaf being related to the information on the bottom leaf, said band having at least two transparent section means along its length separated by approximately one half of its girth, the information being displayed from the top leaf at one transparent section means being continuously keyed to the information being displayed from the bottom leaf at the other transparent section means as the band moves down or across the leaves.
Claim 3
Dependent Claim
17 words
The device of claim 1 wherein said band is continuous and flexible and completely encircles the material.
Claim 4
Dependent Claim
19 words
The device of claim 2 wherein said band has a width substantially less than the width of the material.
Claim 5
Dependent Claim
42 words
The device of claim 2 wherein said band is generally flat on its outer surface, and said device further includes handle means projecting above said surface for grasping by hand when said band is to be moved with respect to the material.
Claim 6
Dependent Claim
54 words
The device of claim 2 wherein said band is formed of a continuous belt of material overlapped upon itself at its ends, said overlapped ends being joined together by fastening means for temporarily fastening said ends and for varying the girth of said belt; whereby said belt can be adjusted for varying size material.
Claim 7
Dependent Claim
17 words
The device of claim 2, wherein said band is formed at least in part of resilient material.
Claim 8
Dependent Claim
17 words
The device of claim 6 wherein said band is provided with elastic sections to provide the resiliency.
Claim 9
Dependent Claim
28 words
The device of claim 2 wherein said band is provided on its inner surface with friction means bearing against the material for preventing unwanted sliding of the band.
Claim 10
Dependent Claim
38 words
The device of claim 3 wherein there is further included an auxiliary, generally opaque, flat element placed in immediate juxtaposition to said band, said flat element cooperating with said band to selectively block out information on the material.
Claim 11
Dependent Claim
85 words
The device of claim 9 wherein said opaque element is a rectangular card placed on one side of said band, the dimension of the side of the card placed next to said band being approximately one-half the girth of said band, all the information to that side of said band being thereby blocked out in spite of the relatively small width of said band, thereby achieving the ease of movement in using a band of relatively small dimension and yet having full information blocking-out capability.
Claim 12
Dependent Claim
34 words
The device of claim 9 wherein the information is isolated by the combined action of the movement of the band and the positioning of the material covered by the band and the opaque element.
Claim 13
Dependent Claim
20 words
The device of claim 1 wherein said band is made of elastic material and holds the material together under compression.
Claim 14
Independent Claim
110 words
A device for selectively isolating information contained on information-bearing material, said material being at least one leaf and forming a semirigid structure, comprising: a continuous, flexible band placed about the material encircling the material, said band having both opaque and transparent section means for selectively blocking out some information and displaying other information on the material, said band comprising two nested elements which are movable laterally with respect to one another and are fitted together in telescoping fashion, said elements being generally opaque but defining between them said transparent section means, the area of said transparent section means being variable by moving said elements laterally with respect to one another.
Claim 15
Independent Claim
110 words
A device for selectively isolating information contained on information-bearing material, said material being at least one leaf and forming a semirigid structure, comprising: a continuous, flexible band placed about the material encircling the material, said band having both opaque and transparent section means for selectively blocking out some information and displaying other information on the material, said band comprising two nested elements which are movable laterally with respect to one another and are fitted together in telescoping fashion, said elements being generally opaque but defining between them said transparent section means, the area of said transparent section means being variable by moving said elements laterally with respect to one another.
Claim 16
Independent Claim
226 words
A method for isolating information by selectively displaying and blocking out information on leaves of printed material comprising the steps of: a. providing a collection of the leaves bound together so that the leaves can be fully folded back upon themselves; b. providing a first array of information on the back of at least a first leaf and providing a second array of information coordinated with said first array on the front of the following leaf, the coordination between said arrays being at least in part a fixed separation distance; c. folding said first leaf over to the bottom of the collection of leaves so that said first array faces outward on the bottom of the collection of leaves and said second array faces outward on the top of the collection of leaves; d. providing an information isolating device having two sections, a bottom and a top section, each of said sections having transparent-information isolating means whose separation measured along said device remains constant; e. slipping said information isolating device over the collection of leaves so that said top section extends over the top leaf and said bottom section extends over said bottom leaf; and f. moving said information isolation device about the face of the leaves so that the coordinated bits of information from said first and second arrays can be easily compared and related.
Claim 17
Independent Claim
226 words
A method for isolating information by selectively displaying and blocking out information on leaves of printed material comprising the steps of: a. providing a collection of the leaves bound together so that the leaves can be fully folded back upon themselves; b. providing a first array of information on the back of at least a first leaf and providing a second array of information coordinated with said first array on the front of the following leaf, the coordination between said arrays being at least in part a fixed separation distance; c. folding said first leaf over to the bottom of the collection of leaves so that said first array faces outward on the bottom of the collection of leaves and said second array faces outward on the top of the collection of leaves; d. providing an information isolating device having two sections, a bottom and a top section, each of said sections having transparent-information isolating means whose separation measured along said device remains constant; e. slipping said information isolating device over the collection of leaves so that said top section extends over the top leaf and said bottom section extends over said bottom leaf; and f. moving said information isolation device about the face of the leaves so that the coordinated bits of information from said first and second arrays can be easily compared and related.
Claim 18
Dependent Claim
50 words
The method of claim 14 wherein said device is a continuous flexible belt, said device being slipped over the leaves so that it forms a continuous loop over and about the leaves, said device being moved about the face of the leaves by running or slipping it about the leaves.
Claim 19
Dependent Claim
61 words
The method of claim 14 wherein said device is a resilient clip having a generally ''''U'''' shaped cross section, said device being slipped over the leaves so that its legs extend over both the bottom and top of the collection of leaves and form said sections, said device being moved about the faces of the leaves by bodily moving it about.
