TECHNICAL FIELD
-
This invention relates to a structure of a means for fast search of relevant pages
in such books, which are mostly reference books. The most popular examples
of them are:
- dictionaries, preferably bilingual, including hieroglyphic and key dictionaries;
- the telephone directories, address books, guide-books;
- directories of firms, commodities and services;
- reference books like "Who is Who", "Yellow pages", "Compass";
- the trade catalogues, price lists;
- the reference allowances, determinants, atlases;
- commercial publications (in particular, users guides of arbitrary hardware
and software);
- indexes of scientific references like "Science Citation Index (SCI)", "Current
Contents (CC)";
- encyclopedias and, especially, encyclopedic dictionaries;
- classifiers for example - International Patent Classification (IPC), International
Commodities and Services Classification (ICSC), and, especially, alphabetic
subject indexes to them; etc., etc.
BACKGROUND OF THE INVENTION
-
It is well known that reference books users waste bulk of time to select pages
bearing relevant textual records. Therefore it is very desirable that the books
should be supplied with simple, comfortable and popular means for as possibly
more fast and exact pages searching.
-
In such a means to easier search of pages, usually there are standard
textual
and/or
non-textual means for identification of contents of book. A detailed list
of them is in a book: Adamov E.B., Krichevsky V.G. Reference Books Designing,
Moscow, "BOOK [KNIGA]", 1981; (see pp. 33-45 and proper illustrations,

-
A textual means of identification always reflect in compressed view (and in particular,
in abbreviated) contents of records of text or entries on pages of books.
The said means are built of graphemes, i.e. of separate symbols of arbitrary alphabet,
characters, letters, digits, figures, ciphers, hieroglyphs, braille and another
simplest signs. Of non-empty sets of graphemes the labels are forming,
and inside them separate graphemes occupy definite positions, while out of
non-empty sets of well ordered labels textual identifiers are forming which are
having in essence a view of separately represented highlighted parts of records
of texts on appropriate pages.
-
In simplest cases a label can consist of the only grapheme, and textual identifier
can include the only label. Herewith it is important to distinguish records of
texts on pages and, fields of records of these texts from records of textual
identifiers and fields of records of labels in such identifiers.
-
It is evident that, the degree of accuracy of pages identification is in direct dependence
from volume of reflection of pages contents in records of textual
identifiers chosen for review and that, the more full will be such records, the
more space can be needed for their placing.
-
Examples of such combination of textual identification means as "contents
list - page numbers" are known to any reader. Contents list has usually view of thesaurus
placed at the very beginning or at the end of a book i.e. it is a list of the
book parts ordered by contents. This allows to represent in detail contents of a
book because the length of headlines records of parts, chapters, paragraphs and
another possible entries can be very large and is limited only by common sense.
-
Naturally, search in contents list allows to determine only the initial and final
page numbers of relevant parts of books, but specific data need to be searched
for by continuous study of pages in detected interval of page numbers.
-
However in reference books, systems usually artificial, alphabetic, as a rule, for
data structuring are used to organize text. Therefore in them for contents representation
instead of practically useless scheme "contents list - page numbers",
other well known scheme "index - page numbers" can be used. An index is
usually an alphabetical list of key terms pointing to page numbers, being placed
as a rule at the end of one-volume books or in the last volume of multi-volume
reference books.
-
While using such a means it is possible to provide exact finding of relevant
information. While using such a means it is possible to provide exact finding of
relevant information. But even infrequent appeals to index with next searching
of necessary pages by primitive thumbing of pages quite weary readers. Therefore
"index -page number" scheme is usually applied in multi-volume one-language
explanatory and encyclopedic dictionaries, which are mainly seldom
used for asking questions.
-
For bilingual dictionaries or telephone directories, predominant in mass of the
reference books, which by themselves are "alphabetical indexes", above mentioned
scheme is needless.
-
In such books as a rule, the running titles serve by textual identifiers of contents.
Usually they have view of records of initial or final parts of text on definite
pages or sides of sheets or spreads (or U-turns, adjacent pages, openings,
double-pages etc.) of books, abbreviated up to two-three initial letters (called
catchwords) placed at margins of pages.
-
Since the catchwords are not visible when the book is closed, their using for
searching needed page still demands practically of the entire examination.
Herewith usually it takes not less, than one minute per one reference and, during
translation of foreign text, lion's share of time has to be wasted for thumbing
of dictionaries.
-
Among the non-textual means of search there are :
- cuts in sheets that can be different by form (rounded, rectangular etc.) and
by position relative to book edge (straight, including: sectional or direct; or
with slant);
- tabs (flags, juts, ledges, stickers, tags, etc., etc.) of sheets;
- half-titles (i.e. rigid insertions or insets between book sections of different
contents);
- usually colored plates (markers) near edge that run to the edge of the sheet
(bled , leaving no margin) and can thus be seen on the edge of the closed
book, which enable to distinguish by eye, book parts of different contents;
- variable size of sheets;
- bibliochrome i.e. printing of each block of pages of the same type of contents
on paper of its own color, it is often used at issuing of telephone directories
and trade catalogues;
- an equal color-code marks not visible on edge, on margins of pages of equal
type of contents.
-
With acquired skills, non-textual means partly simplify orientation of readers in
searching by them of necessary pages. Therefore some users by themselves add
some of such a means to their own dictionaries and reference books.
-
In practice in overwhelming majority, the means for quick search of pages in a
book are some kind of combinations of textual and non-textual means. In these
combinations some non-textual means serve by data carriers being associated
with book sheets and more specifically by carriers of records of textual identifiers.
-
A means for search of pages in a books, mainly in dictionaries, being known
from SU 67904 A 1(1948) can serve by an exotic example of such a combination
of textual and non-textual means. Its textual identifiers include labels of
two types:
- a) the initial alphabet letters by which entries of each group of sheets are
marked and which are placed in middles of such groups on tabs or under
cuts so, that they are visible to user when the book is closed;
- b) the second, third, and sometimes and fourth letters of words specified on
appropriate page; the said letters are placed on margins near edge of these
pages and are inaccessible to user, when the book is closed
-
-
However while using such a means, the growth of accuracy of finding of page
(supposed by inventive conception) leads toward difficulty and slowing down
of procedure of searching.
-
Therefore in practice far more often such popular combinations of textual and
non-textual means are used as:
- stair-step cuts in sheets of dictionaries or telephone directories, which reach
the first pages with certain next in turn alphabet-letters; and letters as identifiers
(thumb-indexes) visible at closed book at appropriate ledges;
- tabs visible at a closed book, which are associated with those pages of
dictionaries, telephone directories or trade catalogues, where words, entries
or the records devoted to definite classes of commodity starting with some
symbol of alphabet, are appearing for the first time; and proper literal or
other symbolic identifiers shown on such tabs.
-
These combinations of the said primitive textual and simplest standard non-textual
means can not ensure identification of each separate page, when the
book is closed. Really, capacity of the majority of reference books is so great,
that the cuts or tabs on all sheets prevent perception of the contents even of
short (up to two graphemes) textual identifiers, and for detailed identifiers containing
more than two graphemes, simply there is no place.
-
For example in the description of background of the invention, in US Patent
4,978,143 there is a review of a lot of unsuccessful attempts to create a compact
and reliable means, capacious for information which are comfortable in use for
access to pages and need no thumbing through pages, mainly for such bulky
and frequently quoted books as Bible.
-
A means for search of pages in dictionaries as in US Patent 5,306,048 and
5,624,138 may be by examples of more successful combined attempts. Non-textual
part of these a means are represented at the edge by bleed plates polychromatic
or monochromatic with differing by background saturation. Herewith
in US Patent 5,624,138 for dictionaries with European alphabets there are:
- a) relatively larger plates defining current first letters of alphabet; and
- b) relatively smaller plates defining second letters of alphabet inside of interval
of pages limited by plates of the first type.
-
-
The plates of the said two types correspond to symbols of the first and second
syllables if they are applied to Japanese syllables alphabets, symbols of which
can be represented by letter or letters of Latin alphabet.
-
Accordingly, there are plates of the first and of the second types on margins of
each page within proper alphabetic interval and they are located bleed at book
edge separately so, that it is possible to distinguish when the book is closed the
large intervals of pages corresponding to the first letter only, and inside the said
intervals the smaller intervals of pages, which correspond to pairs of letters.
-
In any embodiment of the said invention the labels of one or two graphemes
which are placed over the edge and duplicated inside of bleed plates on the
margins of pages serve by textual means of identification of proper pages.
-
Using such a means, readers while book is closed concatenate successively labels
located on the edge over butts of plates or nearby of plates of first and second
types, into textual identifiers, then open the book to check out correctness
of coincidence of other parts of textual identifiers. Such verification is inescapable,
even for labels having only two graphemes which can be placed with difficulty
on book edge nearby or over visible area of the plate of lesser size. Practically
it is impossible to show on the edge of book the thirds, fourth etc. graphemes
for more exact identification of pages.
-
Therefore accuracy of such identification of relevant pages at closed book is not
high.
-
A means for search of pages in a book according to U.S. Patent 4,927,178 by
technical essence is the nearest to the offered. It has:
- a) data carriers being associated with book sheets and visible when the book is
closed, including:
- front sheet which
- precedes sheets bearing the vocabulary entries,
- has view of flat table that consists of horizontal rows and vertical columns
and
- is visible to reader if this sheet serves by cover or if the book is opened on it;
and
- slanting fore-edge (so, that each next page is a little wider than a previous one)
with raster table of horizontal rows and of almost vertical columns visible to
reader when the book is closed placed over it;
- b) textual identifiers of contents of entries of the identical type of sides (of right
or left pages) of sheets or spreads, which are placed over data carriers and consist
of non-empty multitude of hierarchically ordered labels and, more specifically,
consist of literal labels placed by rows in table cells (in original - in
"zones") on front sheet and contain at least one grapheme but preferably up to
four graphemes;
- c) additional digital labels from 1 to n (where in particular, n=7); by them in the
table on front sheet the rows of cells are numbered one by one and some for example
even labels are visible on slanting fore-edge in proper cells of some rows
of the table; and
- d) additional literal indexes which are located on front sheet before beginning
of each row of table and correspond in proper rows to the first letters of textual
identifiers of contents of pages. Such indexes often consist of one letter, usually
identical for a few rows, but can also be of two and more letters in dependence
on dictionary capacity and from use frequency of corresponding letters in beginnings
of words.
-
-
According to inventive intention, amount of textual identifiers of pages contents,
and accordingly amount of cells for inserting them into table on front
sheet in described means must as minimum be corresponding to quantity of
pairs of adjacent pages of reference book.
-
However such means can be effectively used only in books with relatively
small amount of sheets. Indeed, for reference books and dictionaries of large
capacity even on a big front sheet of "encyclopedic" size, it is impossible to
place a table with sufficient amount of easily distinguishable textual identifiers.
Therefore it needs or to sacrifice accuracy of identification of pages or to divide
the book with rigid half-titles to place tables with different sets of textual identifiers
consistently complementing of one another.
BRIEF DISCLOSURE OF THE INVENTION
-
Into the basis of the invention there is put a task by improvement of the fulfillment
of form and mutual disposition of labels in textual identifiers and interrelation
of the said labels among themselves and with data carriers being associated
with the book sheets, to create a means for search of pages in a book so
that, at viewing of the closed book irrespective of its capacity and format they
would secure rise of accuracy of identification of separate pages at reduction of
needed space for the said data carriers.
-
The specified task is solved by dint of next, namely that in a means for search
of pages in a books, which has:
- data carriers being associated with pages of the book and visible when the
book is closed, and
- textual identifiers of contents of records of identical type of pages of sheets
or spreads which consist of non-empty multitude of labels hierarchically ordered
and placed over the said carriers, each of at least one grapheme,
according to the invention
in the structure of the said means,
- each label except first label contains at least one grapheme which distinguishes
record of textual identifier of the marked current sheet from textual
identifier of marked previous sheet;
- each textual identifier contains initial and final label highlighted by a suitable
means;
- the initial label of each textual identifier is placed over data carrier being associated
with that sheet of the book where the text record begins with such
label;
- the final label of each textual identifier is placed over data carrier being associated
with that sheet of the book where the text record begins with such
identifier;
- position of each label in hierarchy of labels of each current textual identifier
is highlighted by at least one of suitable means; and
- labels of identical hierarchical rank in adjacent textual identifiers are highlighted
by identical suitable means.
-
In a described means, labels of several successive textual identifiers, practically
do not repeat one another, because they differ by graphemes and by position in
hierarchy. Herewith each textual identifier which contains more than one highlighted
(i.e. differential) label is dismembered so, that separate labels are placed
over different data carriers visible when the book is closed and being associated
each also with different sheets of the book. Or else:
- each label is highlighted among all others because each label ends one textual
identifier, which conforms to a book sheet marked by this label and just
it binds concrete textual identifier to a concrete sheet;
- each sheet is highlighted (i.e. marked) among all of other sheets by the only
label which is placed over data carriers and associated with given sheet;
- even in very thick reference books, each label associates a unique textual
identifier with its own sheet.
-
Consequently:
- a possibility arises, to use for identification of pages considerably longer and
thus of more informative parts of key words of entries and usually whole
key words, but not of their stumps of two or three letters, how this is usually
adopted for the catchwords of bilingual dictionaries and telephone directories;
and
- a problem of free placing of such long textual identifiers is practically
solved.
-
Because the first and last label of each textual identifier are highlighted by
means accessible for visual or tactile perception, this does not demand excessive
efforts from readers to concatenate a few labels into holistic textual identifiers.
-
The first additional difference means that the suitable means of highlighting of
labels are chosen from a group of the textual or non-textual means, easily distinguishable
by eye or by skin which consist:
- of allographs (as a rule, of fonts) of graphemes used in structure of labels;
- of color or saturation of color of graphemes used in structure of labels;
- of full or partial frames of separate graphemes inside the labels and/or of
separate labels as a whole;
- of positioning of separate graphemes in a structure of labels and/or separate
labels in a structure of textual identifiers;
- of numeration of hierarchical positions (ranks) of separate labels in a structure
of textual identifiers;
- of color or saturation of color, of geometric form or of texture of data carriers
being associated with the sheets of the book; and
- of any combinations of at least two specified means.
-
The above-mentioned term "allograph" here and further is applied in its standard
sense for a designation of such identical in essence but externally different
forms of patterns of the characters, letters, ciphers, hieroglyphs or other graphemes,
by which reliable visual or tactile identification of each separate grapheme
is ensured. By the simplest examples of allographs can serve:
- letters of different size of upper-case and lower-case;
- letters and digits of different standard and non-standard (artistic) fonts, that
differ by geometric form of contours, by dimensions, by lines thickness, by
directions and comers of slope, by elements of ornament etc. etc.
-
Using of allographs for highlighting the differential labels in a means for search
of pages in a book, according to the invention, provides the cheapest and simplest
realization of invention concept. Thus it is especially expedient in such
mass reference books which or are intended for broad range of readers like
cheap bilingual dictionaries or must be regularly updated like telephone reference
books and trade catalogues.
-
In more expensive commercial and/or exclusive reference books of long-duration
use of a type of encyclopedias it is preferable to use in accordance to
the invention such a means in which the differential labels are highlighted by
various color or fluctuation of saturation of color of graphemes and by full or
partial frame of separate graphemes and/or of separate labels.
-
However in case of manufacturing of a means according to the invention for
improvement of books, issued earlier the use of specified color means for highlighting
labels, by moderate price and simplicity would be quite able to compete
with the using of monochrome allographs.
-
Special positioning of separate graphemes in a structure of labels of textual
identifiers is the most expedient if there are sufficient space of data carriers being
associated with sheets of a book; or for rare, alternate, or of incremental use
(for example, in a structure of labels being far away from initial labels in hierarchy).
-
Special positioning of separate mainly of initial differential labels in a structure
of textual identifiers is the most advisable for fast selection by eye or by hand
of current sections in reference books, which can be organized in systematic or
formal, in particular, in alphabetic, key or chronological order, as it is usual for
example in the catalogues of exhibitions devoted to multitude of diverse themes
and/or goods.
-
The numerations of hierarchical ranks of labels can be by most universal means
of their highlighting (of differentiation) in a structure of textual identifiers. It
makes especially obvious to anyone even to unskilled user of reference books
one of the invention essence aspects, of providing of highlighting by same type
of means, of labels of same type (i.e. of the same hierarchical level). However
the numeration requires an increase of the area of data carriers being associated
with sheets of the book. Therefore it is desirable to use the said means in the
reference books for pupils and students.
-
Such a non-textual means, as color, or saturation of color, or geometric form, or
texture of data carriers being associated with sheets of books, are especially desirable
for highlighting (differentiation) of initial labels in a structure of textual
identifiers, since these labels are usually common for a tree of textual identifiers
of many subsequent sheets. Therefore, despite possible rise in price of reference
books equipped with specified means of highlighting of labels their practical
use is very desirable, especially in the advertising catalogues.
-
The data carriers textures recognizable by touch occupy exclusive place among
non-textual means of labels highlighting, since these are usable in books for
blind.
-
And at last, from a number of arbitrary combinations at least of two specified
means of labels highlighting (of differentiation), the most preferable combinations
are:
- firstly, use of at least one upper-case allograph in initial labels of textual
identifiers, which are in addition highlighted in whole by color of graphemes
or of background, that simplifies visual orientation in a means in obedience
to the invention and also search of necessary pages;
- secondly, use of at least one upper-case allograph in initial labels of textual
identifiers, in a combination with partial or complete frame of such labels,
that also simplifies visual orientation in a means in obedience to the invention
and, the search of necessary pages;
- thirdly, combination of positioning of separate graphemes in structure of labels
and numeration of separate labels in structure of textual identifiers provides
the simplest orientation in a means in obedience to the invention and,
the search of necessary pages.
-
The second additional difference means that the data carriers being associated
with sheets of the book are chosen from a group consisting from:
- a) parts of book sheets that are free from main text and have a view of:
- margins of pages, which are at least partially visible to user when sheets are
bent;
- butts of head, tail, and fore edge of sheets;
- combinations of specified margins and butts of sheets;
- b) tabs of suitable form, which are located outside of edge of book sheets and
on which labels are placed; the said tabs are:
- or parts of book sheets,
- or by themselves represent additional details of suitable material, which are
artificially being tied-up, for example pasted up, to the book sheets.
-
-
The margins of book sheet which are free from main text can serve as data carriers
for placing of entire labels at separate sheets of the book if in previous
sheets will be executed cuts to provide viewing of labels at bend of book block.
-
But it is far more effectively the using of such margins for putting at them of
the disappearing raster labels of textual identifiers, which readers can see while
curving of at least part of a book block at some angle.
-
The butts of head, tail, and fore edge of sheets can also serve by basis for raster
textual identifiers, but preferable in such a reference books, which have thick
thematic sections, and one textual identifier corresponds to each of section.
-
The use of combinations of specified margins and butts of sheets by data carriers
being associated with sheets of the book, practically do solve a problem of
space, necessary and sufficient for placing of raster textual identifiers in arbitrary
reference books.
-
The special advantage of such forms of embodiment of a means according to
the invention consists in increased endurance to wearing and in fitness to repairing.
-
Tabs being of suitable form, which are located outside of edge of the book
sheets, irrespective of whether they are parts of book sheets or are additional
details, can serve by most simple carriers of labels. Really a means according to
the invention with such data carriers, without peculiar effort can be designed
and produced in conventional industry of printing and publishing. Moreover, a
means according to the invention, which consist of details being associated, can
be made separately from reference books; and polymeric films, which have endurance
to wearing, may be used as a suitable material for such a means.
-
The third additional difference means that the initial and the final data carrier in
a means are associated with appropriate book sheets near mean part of edges of
these sheets. This difference facilitates access of the readers to the found pages.
-
The fourth additional difference means that only pages margins adjoining to
edge of sheets serve by data carriers, and at least two raster labels are placed
over each of them at different distances from the edge.
-
These labels can be different or identical. If labels are different, it is possible to
use different graphemes (for example, one Latin and at least one of two Japanese
syllabic alphabets) for textual identifiers of identical contents. This, in particular,
permits to replace one full set of textual identifiers by other by trimming
of the sheets in accordance with desire of reader . If labels are identical it is
possible to update a full set of worn textual identifiers by similar trimming of
the book.

DESCRIPTION OF PREFERRED EMBODIMENTS
-
An offered means for search of pages in a book in general case has the following
basic parts (see Fig.1-8):
- data carriers 1, being associated with book sheets, and
- been placed over such carriers 1 and consisting of at least one grapheme the
labels 2 of letters (as on Fig.1-4) or of digits (as on Fig.5-8) of contents of
records, located on the same type (left or right) of pages or spreads (accordingly
entries, key words, catchwords or page numbers may be by these records).
-
The data carriers 1 are conditionally designated by shaded background on Fig. 1
and Fig.5, Fig.3 and Fig.7, Fig.4 and Fig.8 . A general area of each carrier 1
serves by field for record of an appropriate label 2. This area must be sufficient
for records of labels 2 of maximum length, chosen beforehand usually inside
the limits of from one to three and preferably up to two graphemes.
-
In reality by
data carriers 1 can serve:
- a) for embodiment of inventive concept in raster forms wear-resistant but
complicated in manufacturing, - parts of book sheets 3, which are free from
main text and (as on Fig.2 and Fig.6, Fig. 16, Fig. 17 and Fig. 18 and Fig.24)
have a view:
- of margins of pages, which will be at least partially visible to the reader if
sheets 3 are bent;
- of butts of sheets 3, of a book block at the head, tail, and fore edge; and
- of combination of the said margins and butts of sheets 3;
- b) for embodiments of a means according to the invention in more simple forms
convenient for manufacturing, - tabs of suitable shape (not only of rectangular),
which are located outside of edge of book sheets 3 with labels 2 placed over
them, and which are:
- or parts of book sheets 3, (as shown in preferable form of a means embodiment
on Fig. 11);
- or they by themselves (as on Fig. 12) present the additional, of suitable material,
details being artificially associated for example by glue with the book
sheets 3.
-
-
By such materials can be firm paper, and preferably transparent or opaque
wear-resistant films of polymer materials like a polyvinyl chloride, polypropylene
with surface oxidized to improve an adhesive activity, etc.
-
Any data carriers 1, being juts outside of an edge of book block as a whole, give
to the books, which are equipped with a means according to the invention, a
view as on Fig.22. For protection of these carriers I from casual damage the
reference book can have a rigid cover or flap, or more wide cover than sheets 3
with tabs.
-
To prevent need for such protection, tabs as parts of sheets 3, of books can be
located inside the book block, but outside of local edges of previous sheets (located
under cuts), as shown on Fig. 10. In this case the labels 2 will be placed at
margins of pages and can be visible at a bend of a book block through the said
alternated cuts in sheets 3, as shown on Fig.23.
-
The raster form of realization of the invention practically eliminates a question
of protection of labels 2 from wear. So, if in a means at least two identical raster
labels 2 are placed on each of pages' margins adjoining to edge of sheets 3, on
different distances from the edge, which serve by data carriers 1, as shown on
Fig.14, then it is possible to remove at once a whole set of worn textual identifiers
4 on edge, by a simple trimming of sheets 3.
-
The same trick of duplication of raster labels 2, allows to use different graphemes,
in particular, of Latin alphabet and at least of one of two Japanese syllabaries
(kana), in textual identifiers 4, of identical contents. In this case by very
similar trimming of sheets 3, at the request of the reader it is possible to replace
one whole set of textual identifiers 4, by another.
-
Expediently also (see Fig.9) in a means fulfilled as shown on Fig.1 1 or Fig.12
in obedience to the invention, to associate the initial and final data carriers 1,
with appropriate book sheets 3 near mean part of edges of the sheets 3.
-
For lucidity of understanding of these particular variants of embodiments of the
inventive concept, sheets 3 with tabs being outside of edge or, sheets 3 with labels
2 on margins of pages, on Fig. 9 and 10 are conditionally shown by bold
lines.
-
Irrespective of form of embodiment of the invention, data carriers 1 with the labels
2 placed over them, should be located so that at closed book by a simple
bend of book block it was possible to provide reading of textual identifiers 4
(see for example Fig.4 and Fig.8.) Each textual identifier 4 by itself is a non-empty
multitude of hierarchically ordered labels 2 which points onto definite
page of definite sheet 3, or the spread. For implementation of these conditions:
- in the structure of a specified means, each label 2, except initial, contains at
least one grapheme which differentiates a textual identifier 4, of marked current
sheet 3 from a textual identifier 4, of marked previous sheet 3;
- each textual identifier 4, contains the first and the last label 2, highlighted by
further specified suitable means;
- the first label 2, of each textual identifier 4, is put on data carrier 1, being associated
with that sheet 3, of a book where entry or record of text of the
book begins with such a label 2;
- the last label 2, of each textual identifier 4, is put on data carrier 1, being associated
with that sheet 3, of a book, where entry or record of text of the
book begins with such a textual identifier 4;
- position of each label 2, in hierarchy of labels of each current textual identifier
4, is highlighted by at least one of further specified suitable means, and
- the labels 2, of identical hierarchical rank in adjacent textual identifiers 4,
are highlighted by identical means.
-
The whole complex of these conditions will be executed even when some textual
identifier 4 consists of the only label 2 and this label 2 consists of the only
grapheme (for example the literal identifier 4 "I" on Fig.1-4 and as well the
digital identifier 4 "2" on Fig.5-8).
-
However the textual identifiers 4 can be considerably longer than labels 2 included
in them and consist of up to 10 and of more graphemes. Herewith choice
of such length of textual identifiers 4 which is sufficient for recognition of texts
records contents, on separate pages, is predetermined just by these contents, but
not by such geometrical and other parameters of book, as format, amount and
thickness of sheets 3, or sizes of margins on pages etc.
-
From examples shown on Fig.1-8 it is clearly that in essence all labels 2 are
highlighted, because they are put over different data carriers 1, and that those
textual identifiers 4, which contain more than one label 2, are by themselves
thesauri.
-
It should keep in mind, that the graphemes, shown on Fig.4 and Fig.8 on a
white background are not the labels, although they are parts of holistic key
words or page numbers, which are present in records of text of the book. These
graphemes are not placed over data carriers 1 being associated with book sheets
3, they are indicated only for visual representation of way of perusal of textual
identifiers 4 like thesauri.
-
Various textual or non-textual means, easily distinguishable by naked eye or by
the touch, can be used for highlighting labels 2.
-
By examples of textual means of highlighting of labels 2 can be:
- allographs of graphemes, used in structure of labels (as shown, in particular,
on Fig.1-4 upper-case and lower-case letters of the Latin alphabet), and
- shown at the leftmost columns on Fig.3 and Fig.7, numbers of hierarchical
ranks of separate labels 2 in a structure of textual identifiers 4.
-
Of course, represented examples by no means limit the opportunity to use other
allographs and other means of a designation of hierarchical ranks. In particular,
preferably the first letters of various alphabets other than alphabet for records of
labels 2 can be by such a means of ranking.
-
By non-textual means of highlighting of labels 2 can be:
- color or saturation of color of graphemes, used in structure of labels 2;
- full (see Fig. 17-18) or fragmentary (for example, by underlining as on Fig.1-3)
framing of separate graphemes inside the labels 2 and/or separate labels 2
as a whole;
- a positioning of separate graphemes in structure of labels 2, and/or of separate
labels 2, in structure of textual identifiers 4, as shown visually for example
on Fig.2 and Fig.6, where the bold lines in front of letters and behind
the digits, serve by markers to tie up or to associate definite raster label 2,
with the definite sheet 3, of book;
- color or saturation of color or geometrical form or texture of data carriers 1
being associated with book sheets 3.
-
Naturally, in practice, to highlight labels 2 in a means according to the invention,
any combinations at least of two of specified textual and/or non-textual
means can be used.
-
It's also natural that other suitable markers can be used for associating of the
raster label 2, to particular sheets 3, of a book instead of shown bold lines
which, by the way not necessarily ought to be equal to graphemes by height or
exclusively to precede graphemes.
-
Color spots, including different color of separate vertical parts of graphemes
(for able to see) and local modifications of texture of sheets 3, (for the blind)
can be by examples of simplest markers.
-
A special example of such a marking for blind is shown on Fig. 16, where two
raster labels 2, "0Ir" and "1en", from example Fig.3 are visible. Each of these
labels 2 consists of three graphemes, blank spaces and of a marker, namely:
- of a digit, which gives an hierarchical rank for each label 2, in the identifier
4;
- of a marker; and
- of two letters.
-
All graphemes are executed in standard Braille code of six points, as example
by embossed raised dot font on margins of a number of sheets, with blank
sheets (as spaces with no embossing) for convenience of recognition of digits
and letters by the blind readers.
-
Herewith rough margins can be by markers of sheets 3. For convenience of perception
of an example of Fig.16 the first literal grapheme "I" in a label "0Ir"
and digital grapheme "1" and both of literal graphemes "e" and "n" in a label
"1en" on the drawing are framed, and butts of sheets 3 are conditionally shown
by continuous vertical lines.
-
Principles and example of calculation of need in space for data carriers 1, being
associated with book sheets 3 are introduced further. In these principles, there
was taken into account, that despite permanency of height of a visible edge of a
book, its width can be considerably increased, by a bend of a book block as
shown on Fig. 19-24, particularly, in variant of placing of raster labels 2, on a
book fore-edge, which is located opposite to spine (backbone). However, it
should not exclude an opportunity of placing of carriers 1 and on other edges of
a book.
-
By source data for computations serve:
- firstly, the book parameters' values which are given by a book designer and
which designers of a means according to the invention accept as a constant initial
data, namely:
- P - amount of a book sheets, by one unit more than amount of spreads;
- H- height of sheet or fore-edge of a book (as applied to which all of calculation
formulas are given further, for the sake of simplification);
- L - width of a sheet, or a length of head, and tail edges of a book;
- D - thickness of a sheet;
- secondly, the values of parameters, which are directly conditioned by said
source data and influence choice of raster or other variant of embodiment of inventive
concept, namely:
- V = P*D - Minimum visible width of butt of a fore-edge of a closed unbent
book, of 42 mm for the further described example of "English-Russian Dictionary",
and
- W > V - conditioned by methods and means of bending, width of a fore-edge
visible when the book is closed and being reached in the said example
of dictionary after bending of a book block, including a width of adjoining to
edges of pages margins and butts of sheets:
- W1 ≈ 110 mm (about 262% of V ) - while bending at an angle a little
more than 90° preferably with use of prop (like a small tennis-ball for
example) under sheets, as on Fig. 19, or
- W1 = 160 mm (about 380% of V ) - while bending of sheets on an angle
of up to 1800 manually, for example, by pressing on a spine
(backbone) of a book block, as on Fig.20, or by support under a spine,
as on Fig.21.
- thirdly, the values of parameters, which in view of mentioned source data and
values of V and W can be chosen or calculated by the designers of specified a
means on the basis of the general recommendations and/or a common sense,
namely:
- h - minimum height of fields of labels 2, which should be not less than
height of upper-case letters of a font, chosen for these labels;
- m - width of a widest letter of a font chosen for labels 2;
- l - maximum quantity of graphemes in labels 2 (preferably no more than
three and the most preferably, no more than two);
- ν ≥ m * l - minimum width of fields for placing of graphemes of labels 2 on
data carriers 1 in a form of tabs, or of margins near edge under cuts, or of
only butts of several sheets 3 located in succession, in a closed unbent book
(this width is designated by shade of background on Fig.1, Fig.3-5, Fig.7
and Fig.8,
- w ≥ ν - visible width of fields of raster of labels 2, on margins nearby to the
edge and, if there is a wish, on butts of several adjacent sheets 3, of a book
while a book block is bent in an interval of 00-1800 (this width is also designated
as shading of a background on Fig.2 and Fig.6),
- d - thickness of data carriers 1, being associated with sheets 3, of a book,
which usually does not exceed thickness of a sheet "D", or thickness of layer
of paint used for drawing of labels 2, which usually may be neglected.
-
-
Using specified data, it is not difficult to detect, that:
- the designated variables have such a correlation {[W/(P*D)] *D* [H /h]}≥
l*m;
- the maximum possible amount M of labels 2 in a row along fore-edge of a
book (i.e. in a direction downward from top) corresponds to inequality M ≤
H/h;
- the minimum necessary amount N of the said rows of labels 2, on fore-edge
conforms to inequality N ≥ P/(H/h);
- the minimum area s of fields of each label 2, is expressed by the equation s
= h*ν;
- the area S of butt of a fore-edge is expressed by formula S = H*V ≤ H*W;
and
- the total area to be expended in a means according to the invention for placing
of all labels 2, should conform to the inequality P*s ≤S.
-
The above ratios let anybody skilled in the art, to design such a means according
to the invention for search of pages in various books, which effectively
meets the requirements of ergonomics, of aesthetics, of wear-resistant etc.
-
So, if a book block will not be subjected to bending, expense of area of data
carrier 1, for placing of one of the most long label 2, should conform to the inequality
s ≤ S/P= H* V/P. Then, in raster variant with use of butts of unbent sheets
3 only, as data carriers 1, no more than V/v of rows of labels 2 can be placed
across fore-edge.
-
So, if a book block will not be bent, expense of area of data carrier 1, for placing
of one longest label 2, should conform to the inequality s ≤ S/P=H*V/P.
Then, in raster variant with use of only butts of unbent sheets 3, by data carriers
1, no more than V/v of rows of labels 2 can be placed across fore-edge.
-
Because the bending of a book block considerably increases visible width of a
fore-edge, the area s of data carrier 1, spent for placing of one longest label 2,
conforms to the inequality s ≤ H*W/P. Therefore in raster variant with use by
data carriers 1, of margins nearby to the edge and, if there is a wish, of butts of
several adjacent sheets 3, it permits to place from W/w up to W/v of rows of labels
2, across a fore-edge of a book.
-
Accordingly, a raster scheme of placing of labels 2, on butts of only unbent
sheets 3, can be recommended then, when D*H / h ≥/* m. This for example is
possible in some children's reference books with thick cartoon sheets, which
exclude a bending.
-
In view of above mentioned, it is obvious that in books, which permit a bending
of book block, a raster scheme of placing of labels 2, on margins near edges
and, if there is a wish, on butts of several adjacent sheets 3, has substantially
greater prospects of practical use. It should be added here that in such a raster
embodiment, the more bent a book block will be, the more recognizable the
disappearing pictures of labels 2 will be, and that in result of excessive bending,
white spaces can arise between raster bands, as shown on Fig.2 and Fig.6.
-
In comparison with raster variant, the using by data carriers 1, for placing of labels
2, only on margins near edges of some sheets 3, under local cuts placed
like stair-steps in previous sheets 3, preferably alternated with local cuts in subsequent
sheets 3 (Fig. 10 and 23), is less practical.
-
Really, and in such a means according to the invention on a bent book block,
width of a visible part of carriers 1, between nearby labels 2, in a horizontal
row, as well as in raster variant, can conform to inequality (W/P) *(H/h) ≥ l*
m. However reviewing of raster labels 2, requires neither local cuts in sheets 3,
preceding to each of such label 2, nor of equipping of some of book sheets 3,
with transparent insets in some separate parts of a book block. Therefore placing
of labels 2, with use of such cuts or insets can be recommended only for
those reference books, which are issuing at the typographic enterprises possessing
appropriate equipment.
-
The specified inequality, (W /P) * (H /h) ≥ l * m, is most easily feasible by use
of data carriers 1, being juts outside of lateral edge (fore-edge) of book sheets 3.
This is the most preferable variant of a means according to the invention, which
can be separately made and sold with instructions to the users for subsequent
associating with the appropriate reference books; this is considered further on a
concrete example of "English-Russian Dictionary" by V.K. Müller.
-
The 11-th stereotype edition of this dictionary, issued in 1964 by publishing
house "Sovetskaja Enciklopedia" and widely spread in CIS, contains 70000
words and expressions on 1192 pages.
-
In a means for search of pages in a book, only a main corps of the dictionary
and sections: "The list of names", "The list of the geographical names" and
"The list of the most widely used English abbreviations" were supplied by textual
identifiers 4, of last entries (bottom key-words) of odd pages. But sheets of
initial sections "Preface to the seventh edition", "Lexicographical sources",
"About using of the dictionary", "Phonetic & orthographic remarks", "The list
of reductions" and "The English alphabet " were not marked by labels 2.
-
At designing and manufacturing of a real means according to the invention for
this dictionary (see Fig.26 and Fig.27) by constant initial data were taken into
account:
- amount of sheets (and, practically, spreads), P = 596;
- height of a fore-edge H = 250 mm;
- thickness of sheets D = 0,07 mm.
-
Because for equipping of the dictionary, a means for search of pages in a book
on the basis of data carriers 1 in a form of tabs to be associated with sheets 3,
was used, the minimum visible width of the fore-edge face of closed unbent
book was not taken into account. Accordingly, the said values W1 and W2, of
visible width of a fore-edge of closed book, at different modes of bending, were
taken into account only from the point of view of visibility of labels 2 on said
data carriers-tabs 1.
-
And at last, from the same consideration of visibility of labels 2, with regard to
technical opportunities of embodiment of the inventive concept, there were
chosen:
- minimal height of fields for placing of labels 2, on data carriers-tabs 1, being
associated with book sheets 3, h = 5 mm (i.e. equal to height of upper-case
graphemes of a font, a little larger than font of the main text of the book);
- maximum width of graphemes of chosen font m = 2,5 mm;
- maximum amount of graphemes in labels 2, l = 2 and
- minimum width of fields for placing of labels 2, on data carriers-tabs 1, (i.e.
in essence, width of these tabs with no attention to the size of additional
parts, necessary for their fastening to sheets 3, of book) ν = 5 mm.
-
In the example of a real means, conditionally shown on Fig.26 and Fig.27 by
semi-manufactured product been already assembled, onto data carriers-tabs 1,
which after associating with sheets 3, of mentioned dictionaries are always located
outside the fore-edge there were put:
- on obverses (Fig.26) - the literal-labels 2, which consist of parts of records
of last key-words of entries of odd pages, which are partially visible when
rigid top-cover is opened and are completely visible after bending of a book
block; and
- on rear sides (Fig.27) - the digital labels 2, which consist of parts of records
of even numbers of pages, which are partially visible on turned back book
with opened rigid back cover, and are completely visible after bending of a
book block.
-
Herewith by examples of textual and non-textual means for highlighting of
labels
2, in such a real means for the concrete dictionary there were used:
- a) for, mostly of two-letter labels 2 placed on obverses of data carriers 1, as
shown on Fig.26:
- "gray background" and UPPER-CASE letter in the first position only, for
each label 2, of initial (zero) hierarchical rank;
- ''white background" and lower-case letters only, for each label 2, of the next
(first) hierarchical rank;
- "White background" and UPPER-CASE letter in second field only, for each
label 2, of the second (the last for this sample of a means) hierarchical rank;
- "gray background" and both UPPER-CASE letters for labels 2, which in
this specific example concern abbreviations in section "The list of the most
widely used English abbreviations" only; and
- combinations of a sign "*" in the first field with the UPPER-CASE letter in
the second field, and of "an additional saturation of a background" of each
label 2, for initial labels 2 of additional sections of the dictionary;
- b) for mostly one-digit labels 2, (as shown on Fig.27) on rear side of the same
data carriers 1:
- "a gray background" of labels 2 for tens of hundreds of pages and "a white
background" of labels 2 for hundreds of pages, - in bottom row; and
- "a gray background" of labels 2 for tens of pages and "a white background"
of labels 2 for units of pages, - in the leftmost column.
-
-
While using of this real means, the textual identifiers 4, being read as it will be
further described contain:
- in a literal variant - from one up to three labels 2, and in sum of no more
than six letters; and
- in a digital variant - from one up to two labels 2, and in sum of not more
than four digits.
-
In the example of a means, data carriers-tabs 1, being associated with each of
50 successive sheets 3, (or spreads) of a book, form in semi-manufactured
products twelve vertical columns with 50 such carriers 1 per one column (except
the last columns which may have 50 labels 2, excluding a few). Therefore
in this example between nearby data carriers-tabs 1, in horizontal rows there are
usually 50 sheets 3.
-
As the means for the specified dictionary was designed in standard decimal
numeration, as shown on Fig.27, consequently 50 successive digital labels 2
correspond to 100 successive pages. Herewith it turned out that, the digital labels
2, for highlighting of hundreds and thousands of pages it is enough to place
at the only, in particular, at bottom horizontal row of data carriers-tabs 1. Then
digital labels 2, which differentiate units and tens of pages and are located
above the bottom row, can have a view of identical sequences of numbers, located
in vertical columns of semi-manufactured products of specified carriers-tabs
1. That is why in example on Fig.27 there is only one column with digits
placed.
-
Users by themselves can divide assembled sheets of semi-manufactured products
of described type into separate carriers 1, of labels 2, to associate carriers 1
with proper sheets 3, of any reference books according to instruction enclosed
to such a purveyance and to receive required means.
-
Intelligibly, that after scission of semi-manufactured product and associating of
data carriers-tabs 1, with the book sheets 3, the differential labels 2, will be located
as stair-steps along fore-edge. Accordingly, the specified carriers-tabs 1,
will be transformed into markers of pages 3, directly visible when the book is
closed (see Fig.22). Therefore by such a means it is possible to equip the books
which have from tens up to many thousands of sheets.
-
By the way, for the information: in the closed dictionary, according to an example,
total width of only butts of 50 sheets is equal to 3,5 mm. While bending
up to 90° when said butts and adjoining to them parts of margins of pages are
becoming visible; the allowable width of labels 2 can reach 13 mm and, while
bending up to 180° they may reach about 25 mm. These sizes are quite sufficient
for using in the specified dictionary of the raster and other variants of a
means according to the invention.
-
And, to conclude the description of a real example, it should be noted that such
a combined means, with literal and digital identification of sheets 3, of reference
book, is neither solely possible, nor especially preferable. So for the bilingual
dictionaries, for telephone directories and commodity catalogues or price-lists,
and for a number of other reference books not equipped with alphabetic
subject indexes and references to page numbers, on both sides of data carriers 1,
it's expedient to put only literal-labels 2. And vice versa for reference books
equipped with such indexes on both sides of data carriers 1, it may be by most
preferable to put only digital labels 2.
-
Below, essence of the invention is additionally explained by demonstration
examples for two types of a means according to the invention:
- a) with literal identifiers according to Fig. 1-4 and Fig. 16-18, and right parts of
Fig. 22-24, and
- b) with digital identifiers according to Fig.5-8 and left- parts of Fig.22-24.
-
-
In these examples among means of highlighting of textual labels 2, in a structure
of as well textual identifiers 4, there are shown:
- UPPER-CASE letter in the first field of each label 2, of initial (zero) hierarchical
rank;
- only lower-case letters in each label 2, of the first hierarchical ranks;
- Lower-case italic in each label 2, of the second hierarchical ranks; and
- Underlined lower-case italic in each label 2, of the third hierarchical ranks.
-
The specified ranks can be designated and by "key" digits "0", "1", "2" and
"3", as it is visible in a leftmost column on Fig.3. Such a digital highlighting of
hierarchical ranks of literal-labels 2, is desirable to apply only for training of
how to use a means according to the invention. Herewith is obviously, that both
digital and any other textual and/or non-textual means, chosen from above described
group for highlighting of literal-labels 2 should be identical in main part
of a means and in right column of an educational example, which is similar to
shown on Fig.3.
-
From comparison of digits of leftmost and right columns on Fig.3 as applied to
demonstrative examples, shown on Fig. 1-4 and Fig. 16-18 and right parts of
Fig.22-24 it is clearly that if one- and two-literal labels 2, have:
- the top ("zero") hierarchical rank, then they can be or by directly read elementary
textual identifiers 4, or as beginning of longer textual identifiers 4;
- the first hierarchical rank, then they can be as parts of such textual identifiers
4 which consist at least of two labels 2 and should be read together with labels
2, directly previous to them of zero hierarchical ranks;
- the second hierarchical rank, then they can be by parts of such textual identifiers
4 which consist of at least of three labels 2 and should be read together
with labels 2, directly previous to them of zero and first hierarchical rank;
- the third hierarchical rank, then they can be as parts of such textual identifiers
4 which consist at least of four labels 2 and should be read together with
labels 2, directly previous to them of zero, first and second hierarchical
ranks, and so on.
-
Similarly, in digital demonstrative examples (see Fig.5-6 and only informative
Fig.7, and also left parts of Fig.22-24); the key of recognition of hierarchical
ranks of one-digital labels 2, is indicated in the top row on Fig. 8. These ranks
in the given example with one-digital labels 2 coincide with numbers of fields
of digits, used in page,numbers.
-
In a specified key for maximal page numbers of a four digits on Fig.8 the digital
indexes of highlighting of all ranks of labels 2, are shown together with chosen
for given case, also only as an example, by some non-textual means which have
been used on Fig.5 and 6 namely:
- the index "3" conforms to rank of units (and in the page numbers, only on
Fig.8 additionally is highlighted "by the shading of background");
- the index "2" conforms to rank of tens and is highlighted "by full frame";
- the index "1" conforms to rank of hundreds and is highlighted "by black
background in rectangle"; and
- the index "0" designates the rank of thousands and is highlighted" by black
background in circle".
-
Note, that such a specific digital indexes unified for both examples of textual
(both digital and literal) identifiers 4 are used here only for simplification of
perception of variants of embodiments of the inventive concept, and they are
absolutely optional at other practical variants of its realization.
-
The specific features of digital identification of reference books' sheets 3 (in a
described most preferable example of realization of the inventive concept according
to Fig.5-8) in comparison with literal identification consist in the following:
- (1) each digital label 2, placed on a data carrier 1, being associated with a
certain book sheet 3, is highlighted according to its position in a page
number of proper even or odd page;
- (2) each digital identifier 4 always determines a page number of certain
even or odd page of a certain sheet 3 or spread;
- (3) irrespective of how really a means according to the invention is made
(in particular, to show only even as in a considered example or only odd
or even and odd page numbers), any well-ordered multitude of digital
identifiers 4 associated with identical type of sides of book sheets or
spreads, represents by themselves a monotonous increasing sequence (as
a rule by step of "2") of page numbers;
- (4) the zeroes in digital labels 2 usually are not used, for at indicating the
ranks of each digit distinct from zero in adjacent digital identifiers 4, cumulative
considerations of several of successive digital labels 2 allow the
user easily to restore complete digital identifiers 4 and thus numbers of
appropriate pages.
-
-
The first above mentioned feature means that each digital label 2, of example of
means according to the invention consists only of one grapheme.
-
The second said feature means that amount of digital labels 2, of which digital
identifiers 4, of example of a means according to the invention can consist, is in
range from unit up to maximum possible amount of digits in the greatest page
number of the specific reference book.
-
The third above mentioned feature demands to consider an image on Fig.8 by
such a fragment which is included in mentioned sequence of previous and subsequent
page numbers not shown conditionally.
-
The fourth above mentioned feature is not the absolute ban. Really, the digital
identifier 4 which specify page number "2002", in the third row from top on
Fig. 8, can be definite in two ways, namely:
- or by digital label 2, "2" which conforms to a rank of units and that's why is
highlighted in a left column on Fig.7 by a digital index "3", and on Fig.5 "by
the shading of background";
- or by digital label 2 "0", which conforms to rank of hundreds, as shown on
Fig.6.
-
Therefore on "educational" Fig.7 the leftmost column does not contain all possible
set of digital indexes of ranks of digital labels 2 of the rightmost column
and serves only for additional demonstration of conformity of labels 2 on Fig.5
and of identical digital labels 2 in digital identifiers 4 which represent page
numbers shown on Fig.8.
-
It's evident that the described example of a means for the specified English-Russian
Dictionary and, these demo examples by no means exhaust or limit
scope of highlighting of labels 2, but play a role only of some of multitude of
possible illustrations of feasibility of inventive concept.
-
So, in real means of a described type for highlighting of any labels 2 and, in
particular, for a designation of their hierarchical ranks in textual identifiers 4,
not only allographs of graphemes and, monochrome background saturation can
be used but various colors, frames and any other of above mentioned textual
and non-textual means as well.
-
Further, the quantity of hierarchical ranks of textual labels 2 and, accordingly,
maximum amount of such labels 2 in a structure of textual identifiers 4 can be
less or more than four.
-
However it does not influence a principle of using a means for search of pages.
-
In a general case, i.e. irrespective of the particular form of embodiment of inventive
conception the described means is used for search of pages in such a
way.
-
In the beginning, each user studies the instruction, in which there are specified:
- a type of the data carriers 1 used in a real means;
- a type (digital or literal) of labels 2 and of textual and/or non-textual means
of their highlighting, among them in a search procedure a special role belong
to those means which represent hierarchical ranks of separate labels 2, in
textual identifiers 4; and
- rules of reading of textual identifiers 4, and of choice of book sheets 3,
which are highlighted by them.
-
Then, while bending of whole (see Fig. 19 and 20) or of essential part (usually
of about half as on Fig.21) of book block, they open for the review a necessary
part of a means, choosing an angle of a bend in an interval from 0° up to nearly
180° depending on flexibility of sheets and of others above said parameters of
the book.
-
Such a bend for thin wide sheets 3, especially with flexible covers may be easily
reached manually. In case of rigid covers the sheets 3 are curving by pressing
on spine of a book near cover and/or by turning spine with a cover up to desired
angle. A bend of different, more often approximately of equal parts, although,
while clamping of the backbone by cramp, and of any of parts of a
book block toward any side if using of supports under backbone, or under
sheets 3, or under own weight of sheets, is also possible.
-
By bending a book block into one for example right side, they make opened for
the simultaneous review a part (in the example with the dictionary and, on the
drawings of literal-labels 2 only, see right parts of Fig.22-24 and Fig.26) of textual
labels 2, on obverse of data carriers 1, (see right parts of Fig.22-24 and
Fig.26). Analogously, by bending a book block into opposite side, they open for
simultaneous review the other part of textual labels 2, (in the example with the
dictionary and on the drawings, of the digital labels 2 only, see left parts of
Fig.22-24 and Fig.27). Intelligibly, that any non-raster textual labels 2 located
on different sides of the same data carrier 1 correspond to same sheets 3, of
books.
-
Further, they train themselves in recognition by eye or to the touch of hierarchical
ranks of labels 2, and in reading of thesauri, which are enabling mentally to
form textual identifiers 4, and to use them for choice of relevant sheets 3.
-
After doing of described training the user of a means according to the invention
can be freely oriented in structured multitude of textual labels 2 or, what is
same, in AND-OR tree of letters of textual identifiers 4, (see Fig.4), as well as
in sequences of digital labels 2.
-
To the user it will be clearly that at literal identification, the literal label which
has zero hierarchical rank and consists of the only grapheme "I", has no "subordinated"
labels 2, and by itself serves by textual identifier 4, which points to a
definite sheet 3, of reference book.
-
Further not less clearly, that the two-letter label 2 "In" of the same zero rank
has four "subordinated labels" 2 - "te", "r", "rn" and "et". From all these labels
2, they can mentally assemble such different textual identifiers 4, which are associated
with different book sheets 3, as:
- textual identifier 4 "In" consisting of the only label 2;
- textual identifier 4 "Inte" consisting of two labels 2;
- two textual identifiers 4 "Inter" and "Intern", each of three labels 2; and
- one textual identifier 4 "Internet", which consists of four labels 2.
-
Analogously, three textual identifiers 4 "Ir" "Iren" and "Is" can be mentally
formed in process of visual or tactile perception of AND-OR tree of labels 2.
-
The initial labels 2, of zero rank together with the pointing final labels 2, of any
other hierarchical ranks in each of specified in this example and in any of similar
arbitrary textual identifiers 4, will specify direct access to quite definite
sheets 3, of books.
-
Naturally, a lot of another words can exist in intervals between words represented
by adjacent
textual identifiers 4, in real dictionary or in another reference
book. The words which include according to Fig.4 such rows of graphemes as:
- "Intend" "Internal" and "Ira" which are not the textual identifiers can be by
such examples. Therefore the accuracy of access to a desired word or entry of
textual record with help of a means according to the invention usually lies
- within ± 1 sheet.
-
-
Rules of perusal of digital identifiers 4, of pages of reference books are usually
simpler, than similar rules for literal identifiers 4.
-
For example, the perusal of digital identifier 4, which specifies the last
(conditionally framed) page number "2016" on Fig.8, consists in the next:
- by using non-textual means of highlighting "a black background in a circle"
they choose among previous digital labels 2 a nearest label 2 "2" which conforms
to the rank of thousands (visible in the second row from top on Fig.5-8);
- beneath specified row, by using non-textual means of highlighting "a black
background in a rectangle" they choose from previous digital labels 2 a
nearest label 2 "0" which conforms to the rank of hundreds (visible in the
third row from top on Fig.6 and Fig.8);
- still beneath, by using non-textual means of highlighting "the full frame with
shading of background" they choose from previous digital labels 2 a nearest
label 2 "1" which conforms to the rank of tens (visible in the fourth row
from bottom on Fig.5, Fig.6 and Fig.8);
- and at last from following digital labels 2, they choose such not highlighted
specially nearest label 2 "6" which conforms to the rank of units (visible in
the bottom row on Fig.5-8). In result mentally concatenate a digital identifier
4 which gives an access toward the page with proper page number "2016".
-
Thus a means similar to ones shown on Fig.22-24 and Fig.26-27 permit directly
to read labels 2, to concatenate them and to choose suitable textual identifiers 4,
to press down a necessary marker on edges of flabby sheets 3, and to divide a
batch of sheets 3, between necessary adjoining pages with an error, as a rule,
within not more than ±1 sheet 3.
INDUSTRIAL APPLICABILITY
-
The offered means for fast search of pages in a closed book, is rather simple,
and can be produced on the modern printing equipment while issuing of any ordinary
editions and reference books.
-
The most widely, simply and in a cheapest way while manufacturing it can be
used if placing labels on tabs of sheets of reference books, because in such
cases the equipping of books by a means according to the invention is possible
even after issuing and putting books onto sale.
-
Experimentation with a means according to the invention showed, that a steady
skill of choice of necessary adjoining pages or spreads may be reached by readers
in a few minutes or during up to half an hour.
