IMPROVED HANDMADE ARTICLE OF LINEN AND/OR BEDCLOTHES
The present invention refers to an improved handmade article (or object) of
linen
and/or bedclothes, such as typically but not exclusively a mattress cover, a
pillow,
a seat cushion on chairs, especially wheelchairs for the disabled.
As widely known, the evolution of the human species has had the result not
only to
connote the body of a person the assumption of the upright position but also
to
conform the vertebral column according to a sinusoidal arrangement (or to an
S).
The S-shape, on one hand, is optimal for the functionality of the movements
and
distribution of loads that the backbone must support, on the other hand,
however,
makes the column very vulnerable and subject to diseases such as lumbar
arthritis
and cervical, back pain, low back pain, back-related pathologies, herniated
disc,
kyphosis, scoliosis and so on.
In order to avoid to go with or, better, to prevent these pathologies, it
seems
increasingly crucial that, during sleep, rest, sitting or other conditions in
which a
person's body rests to some extent on a support structure, the anatomical part
of
the human body in support cooperates by contact with comfort elements such as
mattresses, pillows, mattress covers and even more through which the backbone
succeeds in keeping a posture almost equivalent to that one taken by the
person
when rests in standing position.
Otherwise, indeed, the backbone is forced to place itself in incorrect
positions that
cause the increase of the mentioned painful pathologies and the automatic
stiffening of the muscles of the body.
Another factor to be carefully assessed when considering the conditions under
which a person sleeps, rests or remains seated concerns the air recirculation
guaranteed by the bedclothes (otherwise definable also as garments or set
cloths)
which the support structure (bed, chair, sofa, bench and so on) on which the
person stands with her own body is provided with.
Moreover, as a whole, the comfort elements of such a support structure must be
able to prevent or at least minimize other diseases such as allergic forms.
It is, therefore, evident that mattresses, blankets, duvets, mattress covers,
pillows,
cushions and similar handmade linen and/or bedclothes articles must guarantee
a
1
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
healthy air circulation in order to optimize body transpiration and avoid
humidity
stagnation, thus ensuring a constant and dry heat.
At the same time, it is important that these bedclothes elements which can be
placed on a bed or in any case lied on a generic seating or resting surface,
such
as a sofa, an armchair, a chair, a bench, a deckchair or directly on the floor
(or on
the carpet resting on it) of a room in a house, can be washed and disinfected
to
ensure adequate hygiene conditions that protect the human body from mites,
bacteria, molds and dust, which often cause allergies and infections for
people.
It should be considered the fundamental role that could have a comfort element
or
handmade article (or object) of linen and/or bedclothes, such as for instance
a
covering or a cushion, in relation to each of the factors listed above when
applied
over a seat, usually with wheels, on which disabled persons are forced, in
spite of
themselves, to spend most of the day.
The invention concerned herein described bases in particular on the properties
of
breathability, linked to hygroscopicity (or hygroscopy) and of
thermoregulation,
linked to the insulation, typical of a comfortable handmade article (or
object) or
element of lined and/or bedclothes, whose role in determining effective
sitting or
resting conditions for the person results not only increasingly less
negligible but
rather crucial and essential.
Briefly, it should be noted that hygroscopicity means the ability of a
substance or a
material to readily absorb the molecules of water present in the relative
surrounding environment, in this case the sweat of the human body of the
person,
which specifically are subsequently released thanks to the breathability
concerned.
By thermoregulation, instead, it is meant the capability of keeping constant
the
temperature of a body, independently from the temperature variations of the
external environment, and, thus, in other words, the capability of some
materials to
keep constant the temperature of the body, handmade article or object made
with
them, thanks to their insulation properties.
The main limitation of the most common and traditional handmade articles (or
objects) of linen and/or bedclothes, such as typically a mattress cover or a
cushion, of the known art derives from the conditions of thermoregulation and
breathability of the user's body coming into contact with them: although high,
they
2
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
are not ideal for the physical integrity of people, especially if with
rheumatism
problems or disabled people forced to bed or wheelchair for a long part of the
day.
Indeed, the constructive shape and the materials with which they are made do
not
allow the handmade articles of linen and/or bedclothes of the known art to
release
the humidity to a significant and effective extent.
consequently, the classic handmade articles (or objects) of linen and/or
bedclothes, such as a mattress cover, a cushion or a pillow, available on the
market, on one hand, expose the person's body to environmental conditions that
are not properly ideal and unfortunately capable of causing rheumatism
problems,
and, on the other hand, make the moments of rest or relax, sometimes crucial
for
people like the disabled, the elderly or for those ones who suffer from
chronic back
problems, less comfortable.
At the same time, moreover, the handmade articles (or objects) of linen and/or
bedclothes, such as a mattress cover or a cushion, of the known art available
on
the market are not washable for example in water, so the conditions of hygiene
and cleaning offered by them to the user are precarious or not entirely
adequate
and satisfactory.
The mattress cover described in the Italian patent nr. 1380622, whose
ownership
belongs to the same applicant requiring the patentability of the present
invention
and whose technical teachings are incorporated herein by reference, remedies
to
these drawbacks, although in incomplete and not totally satisfactory way.
Indeed, if it is true that the mattress cover described in such a prior
document
improves the breathable and thermoregulating properties of the mattress covers
then known, thanks to the interstitial air (hygroscopic and transpiring)
chamber
defined by two distinct bedclothes items facing and opposite each other and by
junction means that, applied mainly though not exclusively at perimetrical
level,
firmly couple mutually these bedclothes items, it is equally true that this
constructive device, even in its effective and revolutionary innovation, does
not
allow such a mattress cover to reach optimal levels of the two properties
mentioned above ¨ breathability and thermoregulation ¨ and, consequently, does
not offer the best possible conditions of comfort to people who spend moments
of
rest or relax lying in bed or sitting on a sofa, a chair, an armchair and so
on.

CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
By return, the specific handmade article of the above mentioned Italian patent
exposes the person's body to environmental conditions that are not exactly
ideal,
yet capable of causing problems of rheumatism, and makes the moments of rest,
relax or normal daily life (in the case of disabled people forced to bed or
.. wheelchair) that the same person spends on it less comfortable, albeit to a
noticeably reduced extent with respect to the handmade articles comparable to
it
of traditional and more dated constructive conception.
Starting, therefore, from the awareness of the aforesaid drawbacks suffered by
the
current state of the art herein considered, the present invention seeks to
completely and effectively overcome them.
Particularly, main purpose of the invention is to devise an improved handmade
article of linen and/or bedclothes that improves the hygroscopic and
transpiring
properties (or, in other words, the breathability) compared to those ensured
by
known similar handmade articles of more advanced and modern embodiment.
In other words, primary purpose of the present invention is to make available
an
improved handmade article of linen and/or bedclothes which is more breathable
with respect to the equivalent articles of the prior art.
Within this scope, it is therefore task of the present invention to provide an
improved handmade article of linen and/or bedclothes which allows to further
limit
with respect to the known technique the physical problems suffered by the
rheumatism of a person while resting, sleeping, sitting or otherwise lying.
It is another task of the invention to develop an improved handmade article of
linen
and/or bedclothes that improves the quality, making it more comfortable and
healthy, of the moments of rest, relax or normal daily life (in the case, for
example,
of people force to bed or wheelchair) spent by a person during a day.
It is a further purpose of the present invention to indicate an improved
handmade
article of lined and/or bedclothes which, with respect to the known art more
directly
comparable thereto, allows to improve the thermoregulation property.
It is a last but not least purpose of the present invention to give substance
to an
improved handmade article (or object) of lined and/or bedclothes that is also
hygienic since hypoallergenic, anti-mite and washable in water, as well as
very
soft and light and pleasant to touch and use.
4
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
Said purposes are achieved by means of an improved handmade article of linen
and/or bedclothes according to the attached claim 1, as hereinafter referred
for the
sake of exposure brevity.
Further applicative detail features of the improved handmade article (or
object) of
linen and/or bedclothes of the present invention are contained in the
respective
dependent claims.
The aforementioned claims, specifically and concretely defined below, are
intended as an integral part of the present description.
Advantageously, the improved handmade article (or object) of linen and/or
bedclothes of the invention, on which a person typically supports at least a
part of
her body (her own head in case of a pillow or the whole body in case of a
mattress
cover) during the hours of rest or if disabled sits during daily life, is able
to further
reduce, bringing it to minimum levels, the humidity content of the surrounding
space, significantly lowering its value compared to equivalent handmade
articles
of know art, while at the same time keeping the body temperature of the person
who uses it constant.
In essence, the improved handmade article of linen and/or bedclothes of the
invention is more transpiring and thermoregulating with respect to equivalent
handmade articles of known type even of more advanced constructional design.
This is thanks to the significantly innovative technical feature which the
improved
handmade article of the invention is provided with and which is embodied in
the
fact that at least one of the inner spacer tabs (as defined in the
aforementioned
claim 1) of at least one of the padded and quilted bedclothes items ¨ which
constitute the main components of the handmade article of linen and/or
bedclothes
itself ¨ presents one or more through holes which place in mutual
communication
at least two of the adjacent quilted panels adjacent each other and belonging
to
the same bedclothes item, so that the circulation the air inside at least one
of
these bedclothes items and/or the hygroscopic interstitial chamber defined by
them is maximized or optimized, or at least increased with respect to similar
handmade articles of the prior art.
Equally advantageously, with respect to the prior art, the improved handmade
article (or object) of linen and/or bedclothes of the current invention makes
the
5
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
moments of rest, relax or normal daily life of the user more comfortable and
healthy who can thus appreciate or live these moments with greater serenity
and
satisfaction, with a consequent improvement in the quality of life.
Equally advantageously, the improved handmade article of linen and/or
bedclothes
of the invention further reduces with respect to the known technique the
physical
problems to which a person is exposed while resting, sleeping, remaining
seated
or otherwise lying on a generic support structure comprising the object which
the
invention itself is oriented to.
Still advantageously, as already pointed out above, the improved handmade
article
of linen and/or bedclothes of the invention offers levels of thermoregulation
higher
than those ones provided also by the comparable products of more modern and
recent design (shown in the Italian patent No. 1380622 in the name of the same
owner of the titled industrial property right herein presented), allowing in
respect to
the latter to keep more effectively constant the body temperature of the
person
who uses it.
Advantageously, moreover, the improved handmade article (or object) of linen
and/or bedclothes of the present invention is an article of high quality and
durability, especially in the case where it is preferably made of down and, in
particular, in Siberian and Tibetan down.
More specifically, each bedclothes item (or set cloth) of the improved
handmade
article (or object) of linen and/or bedclothes of the invention is,
preferably, padded
with the down flakes taken from the underneck and from the chest of the goose
which are full-bodied and soft, and which, moreover, especially if geese are
bred
to their full maturity or live in the wild in a harsh climate, are
particularly elastic and
resistant.
The natural properties of goose down, therefore, such as hygroscopicity,
insulation, elasticity and volume, allow to create an anti-allergic and anti-
rheumatic
cover that, in the invention, helps to promote healthy body transpiration and
a
comfortable rest for the user.
The specific structure, the absolute naturalness and the careful selection of
the
materials used for its components allow to provide a long warranty to the
improved
handmade article of linen and/or bedclothes of the invention described herein.

WO 2019/102448 PCT/IB2019/050737
Said purposes and advantages will become clearer from the following
description,
relating to a preferred embodiment of the improved handmade article of linen
and/or bedclothes of the present invention, given by indicative and
illustrative, but
not !imitative, wat with the aid of the attached drawing tables in which:
- figure 1 is a longitudinal sectional view of the improved handmade article
(or
object) of linen and/or bedclothes of the invention;
- figure 2 is a cross sectional view of the improved handmade article (or
object)
of linen and/or bedclothes of the invention.
The improved handmade article of linen and/or bedclothes of the invention is
shown in figure 1 where it is globally numbered with 1.
As it can be seen, such an improved handmade article 1, typically although not
restrictively and not exclusively constituted by a mattress cover, comprises
two
padded bedclothes items 2, 3 which:
= are well distinct and identifiable each other and in any case one facing
and
opposite the other;
= are quilted according to sectors (or panels or squares) scheme or modular
sectors 4, as better shown in figure 2;
= comprise a plurality of inner spacer and dividing tabs 5 which are
arranged
inside the padded bedclothes items 2, 3 which are firmly connected with and
which separate each other the quilted squares 4 of each of the padded
bedclothes items 2, 3;
= are connected each other through junction means, indicated as a whole
with 6,
in such a way as to define a hygroscopic interstitial chamber 7 suitable to
increase the breathability and thermoregulation of the article 1.
In accordance with the invention, each of these spacer tabs 5 of both the
padded
bedclothes items 2, 3 presents two through holes (each numbered with 8) which
place in mutual communication the quilted modular squares (or sectors) 4
adjacent
each other and belonging to the respective bedclothes item 2, 3, so that the
circulation of air A inside not only the hygroscopic interstitial chamber 7
defined by
the bedclothes items 2, 3 but also the bedclothes items 2, 3 themselves is
maximized or optimized, or at least significantly increased compared to what
can
be found in similar handmade articles of the prior art.
7
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
Particularly, each of the aforesaid through holes 8 presents, on preferred but
not
binding basis, a circular profile having a diameter of a value in the range of
2+5
cm.
Even more preferably but not restrictively, the diameter of each of the
through
.. holes 8 is equal to 3 cm.
In addition, moreover, the spacer tabs 5 are also connected with the
corresponding bedclothes items 2, 3 preferably through the junction means 6.
In preferred and advantageous manner, each of the inner spacer tabs 5
comprises
a movable and flexible portion (in this case, for instance, not affected by
the
junction means 6 of the type that will be described hereinafter), not shown
for the
sake of exposure convenience, arranged in correspondence of at least one of
the
through holes 8 in such a way as to widely but not completely close it, so as
to
allow, on one side, circulation of the air A between the quilted squares 4
and, on
the other side, properly, to prevent accidental and uncontrolled migration,
transfer
or passage of the padding (of the type that will be highlighted in the
following of
the description) from one to another of the quilted squares 4 of the
bedclothes
items 2, 3.
Such a movable and flexible portion might belong to one or more of the spacer
tabs 5 (with which it is thus monolithic) or, less frequently, might be
constrained
.. only partly to it through suitable union means or, possibly, held in
position (at the
through hole concerned) by the aforesaid junction means applied at the
quilting of
the squares or modular sectors.
Each of the padded bedclothes items (or set cloths or portions) 2, 3 includes,
at
preferred but non-binding title, a fabric envelope 9, 10 filled with
filamentary
elements suitable to give it softness, elasticity, hypoallergenic,
thermoregulation,
hygroscopicity, breathability features. More in detail, the fabric envelope 9,
10 is
made of a material comprising cotton.
Preferably but not necessarily, the material of the fabric envelope 9, 10 also
comprises silver yarns inserted into the cotton weft, giving rise to a silver
textile
fiber which represents an innovation which has been introducing almost for
some
years into the latest generation products of the sector of linen and/or
bedclothes,
in order to meet the growing need for health, well-being and hygiene of the
end
8
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
user: the properties of the silver textile fiber allow, indeed, a significant
increase in
the level of comfort of people.
This arises from the fact that silver ions present remarkable hygienic and
antibacterial properties and are thus used to make different types of objects,
including also textile fibers.
The silver fiber fabrics are obtained from the permanent and homogeneous union
of a layer of pure silver that, through the use of nanotechnology, is firmly
bonded
to the surface of the fiber: it is a process that allows the fiber to keep, at
the same
time, its traditional textile and tactile consistency features.
The silver textile fiber is:
= antibacterial, antifungal, anti-mite: silver significantly reduces
bacteria and
fungi proliferation by shortly ¨ less than an hour ¨ eliminating 99% of
bacteria);
= anti-odor: silver neutralizes the microbial flora responsible for the
formation of
bad odors;
= hypoallergenic, natural, non-toxic: the fiber is covered with pure
natural silver
and presents no toxicity risks;
= antistatic: silver high conductivity allows rapid electrostatic charges
dissipation;
= breathable: this fabric fiber guarantees the optimal passage of air and
steam.
In other embodiments of the improved handmade article of linen and/or
bedclothes, not shown in the attached drawing tables, the cotton constituting
the
material of the fabric envelope of the padded bedclothes items can be
subjected to
a specific antibacterial treatment in silver solution, performed in the
finishing phase
to ensure an antimicrobial, antiallergic and anti-odor action to the cotton:
such a
treatment fully prevents the uncontrolled bacteria proliferation on the fabric
surface.
As far as the filamentary elements contained in the fabric envelope 9, 10 are
concerned, they comprise any of the padding elements chosen from the group
consisting of duvets, wool, horsehair, feathers and synthetic fibers
(polyesters,
microfibers and the like).
Preferably and advantageously, the duvets are of the Siberian, Tibetan,
Canadian,
Hungarian and/or similar type and absorb the moisture to allow the fabric
envelope
9, 10, which a person's body comes into contact with, to remain dry.
9
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
The duvets (for example that one shown above) are thermo-regulating, offering
a
good thermal insulation (thanks to the air circulating among the fibers of the
duvets
themselves) which allows to keep the temperature of the person's body constant
and to homogeneously spread the heat.
More specifically, each of the duvets consists of an extremely light three-
dimensional ribbon which comprises a central core from which a plurality of
beards
branches out suitable to create a multiplicity of air chambers where the air
which
creates the thermal insulation useful for maintaining body temperature is
kept.
The set of duvets flakes gives the improved handmade article 1 of the
invention
advantageous features of elasticity, volume and lightness, unlike the
traditional
feather structure (in any case falling within the inventive concept underlying
the
present invention referring purely to a possible variant thereof) which is
rigid, flat,
heavy and with little ability to absorb air.
It should be noted that the duvets contained in the fabric envelope 9, 10 are
in a
predetermined and adequately calibrated quantity, correlated with the
supporting
function performed by the improved handmade article of linen and/or bedclothes
1
of the present invention.
It is evident that the composition just described of the padded bedclothes
items 2,
3 of the improved handmade article of linen and/or bedclothes 1 exclusively
claimed herein contributes to the achievement of the prefixed purposes of the
present invention and to get the advantages previously listed.
As regards the modular squares or sectors 4, they are in this case mutually
identical and side-by-side along at least a plurality of first linear
directions X and
also along a plurality of second linear directions Y, orthogonal to the first
linear
.. directions X.
It is understood, however, that in other embodiments of the improved handmade
article of the invention, not shown hereinafter, the modular squares or
sectors
could be placed side-by-side only along a single linear direction, so that to
form for
instance a cushion or a pillow of special and elongated constructive
conception.
Moreover, each of the modular squares or sectors 4 is composed by an upper
surface 11 and a lower surface 12 spaced apart each other at the opposite ends
11a, 12a, 11b, 12b by a first length of a value lower than that one of a
second
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
length which spaces apart the central areas 11c, 12c of the upper surface 11
and
of the lower surface 12: it follows, therefore, a rounded shape for each of
the
modular squares or sectors 4 of the padded bedclothes items 2, 3.
With particular reference to the inner spacer tabs 5, it is emphasized that
each of
them is preferably but not exclusively made of cotton and is applied
internally at
the opposite ends 11a, llb and 12a, 12b respectively of the upper surface 11
and
the lower surface 12 of the modular squares or sectors 4.
From what has been described so far, therefore, it derives that the only one
hygroscopic interstitial chamber 7 define in this case by the padded
bedclothes
items 2, 3:
= is included between the side flaps 2a, 3a respectively of the first
bedclothes
item 2 and the second bedclothes item 3;
= extends substantially for the entire dimensions of these side flaps 2a
and 3a,
coinciding with the closed volume defined therein.
Finally, as far as the junction means 6 are concerned, they are preferably but
not
necessarily applied at the entire perimeter (or of the entire perimetrical
length)
defined by the side flaps 2a, 3a of each of the padded bedclothes items 2, 3.
According to the preferred embodiment described herein of the invention, the
junction means 6 comprise a double perimetrical seam section, of the type per
se
known in the sector concerned, distributed according to a closed path along
the
entire perimeter defined by the side flaps 2a, 3a.
Other variants of the improved handmade article of linen and/or bedclothes of
the
present invention, not shown in the enclosed tables, may provide that the
junction
means include a number of perimetrical seam sections different than two, such
a
number being able to vary in function of the constructive choices starting
from one.
As further alternative of the improved handmade article (or object) of linen
and/or
bedclothes of the invention, not accompanied by reference figures in the
following,
the junction means could comprise:
- a perimetrical neckband provided with a first face facing outwardly and
with a
second face facing the hygroscopic interstitial chamber;
- at least two perimetrical seam sections, applied one along the upper edge
and
the other one along the lower edge of the perimetrical neckband.

CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
The improved handmade article (or object) of linen and/or bedclothes 1 of the
invention is washable simply in water and neutral soap and can, therefore, be
rinsed and dried in air and in shade.
For a perfect drying, it is in particular necessary to shake the improved
handmade
article of linen and/or bedclothes 1 and frequently separate the content of
the
fabric envelope 9, 10 from the envelope itself, thus preventing halos
formation.
It is possible to wash the improved handmade article of linen and/or
bedclothes 1
even in the dry cleaner's with water at 60 C, neutral soap and thorough
rinsing
too, ensuring over time high hygienic conditions that protect against mites,
bacteria, molds and powders, which often cause allergic and infectious
diseases.
Drying of the improved handmade article of linen and/or bedclothes 1 of the
invention can take place with a dryer (or drier).
By virtue of the description just given, it is understood, therefore, that the
improved
handmade article (or object) of linen and/or bedclothes of the present
invention
achieves the purposes and reaches the advantages previously mentioned.
The innovative concept underlying the invention ¨ represented by the features
contained in the characterizing part of the attached claim 1 ¨ allows to
improve,
triplicating, the movement of air inside the improved handmade linen and/or
bedclothes article, with all the benefits already underline that this entails.
Upon execution, changes could be made to the improved handmade article of
linen and/or bedclothes of the invention, consisting, for example, in a number
of
bedclothes items (or set cloths or portions) other than that one previously
highlighted and visible in the attached figures, since this number may vary at
will
starting from two.
In addition to this, other embodiments of the improved handmade article of
linen
and/or bedclothes of the invention, not shown in the attached tables, could be
present in which the junction means connect the padded bedclothes articles
each
other in such a way as to define more than one inner hygroscopic interstitial
air
chamber, even in this case such a number being able to vary according to the
constructive needs starting from one.
Furthermore, in further embodiments of the improved handmade article of linen
and/or bedclothes of the present invention, yet not illustrated in the
following
12
CA 03127616 2021-07-22
WO 2019/102448 PCT/IB2019/050737
drawings, only one or only some of the spacer tabs could present one or more
of
the through holes as above constructively and functionally defined.
In addition, in optional and alternative embodiments of the invention, still
not
shown in the figures of the attached drawing tables, the spacer tabs affected
by at
least one of the through holes previously defined could belong only to one or
some
of the padded bedclothes items forming the improved handmade article of linen
and/or bedclothes that is exclusively claimed herewith, letting the spacer
tabs of
the remaining padded bedclothes are depict of through holes, which does not
affect the advantage basically brought by the present invention.
In further addition, other embodiments of the improved handmade article of
linen
and/or bedclothes of the invention, not shown in the following, could provide
that
the through holes are unevenly distributed on the various spacer tabs of at
least
one of the padded bedclothes items: other words, in certain embodiments of the
invention, one or more of the spacer tabs could be depict of through holes or,
in
certain other embodiments of the invention, one or more of the spacer tabs
could
have a number of through holes other than that of one or more of the remaining
spacer tabs.
In this regard it is specified that the number of through holes made in at
least one
of the inner spacer tabs ¨ which clearly means that, in some embodiments of
the
invention, some spacer tab could lack these through holes ¨ is variable
according
to the project choices starting from a minimum of one.
It is, finally, clear that several other changes could be made to the improved
handmade article of linen and/or bedclothes concerned, without departing from
the
principle of novelty intrinsic in the inventive idea expressed herein, as it
is clear
that, in the practical implementation of the invention, materials, shapes and
sizes
of the illustrated details could be changed, as needed, and replaced with
others
technically equivalent.
Where the constructive features and techniques mentioned in the following
claims
are followed by reference numbers or signs, those reference signs have been
introduced with the sole objective of increasing the intelligibility of the
claims
themselves and therefore they have no limiting effect on the interpretation of
each
element identified, by way of example only, by these reference signs.
