2. The analysis of the core component shall reveal the following features:
1. Circular cross-section implies a uniform distribution of the discrete particles that
constitute the mass distribution map.
2. The packing of 70% of the original conventional mass in just 25% of the diameter
brings in greater compactness with so much so additional discrete particles crowding
either side of the central axis that makes the cylinder of the core concentric under stress
with higher rotational torque
3. The centrifugal force originating from the core shall be determined by the linear
velocity; approximately a multiple of 13.46 on the conventional cylinder. The kinetic
energy transmitted along the radial direction outwards shall be phenomenal (1200 % +);
an intense energy at that.
4. The function y describing energy transmitted outwards shall be denoted by y=f(x1)
where x1 is determined by the following variables:
a) Volume of displaced particles as defined by the torque summation on either side of
the axis,
b) The entropy in the system as defined by the density of the discrete particles in the
mass and

3. c) The entropy gradient across cut-off lines -1, 2 and 3 in terms of torque stability as
determined by the material stability to temperature, collisions energy (high impact-low
frequency as well as low impact-high frequency) and specific material strength across
the cross-sectional masses.
5. The constant C1 in the equation is defined by the domain strength in terms of spatial
configuration of the energy distribution at the interface with the next boundary of the
composite.
The interface between the core-1 and the core-2 is vital in interpreting the trajectory of
the energy line as it permeates through the structure with varying particle density and
torque values.
There shall be an inherent displacement with an angle determined by the relative
ratio of C1 and C2; both constants being determined by the same conditions as
explained above in the respective medium.
This deflection in term defines the volume of air displaced and the sharpness of the
curvature profile at the edges that change the vector of displacement of energy normal
to the impact.

4. In short, this singular important ratio defines the configuration of the rate of change of
the normal since the energy profile is spread over a greater curvature thereby reducing
the specific energy at the boundary and aggregating to a slower rate of change of the
normalization. This, in turn, spreads the distribution of the drawing vector on the fiber
mass at the eventual periphery on a larger cross-section thereby ensuring a gradual
separation leading to individualization and higher fiber freedom.
Energy deflection at the boundary is the first important derivative of the design proposal.
The structural analysis of the core-2 body has the following derivations:
1. The body is concentric with a balanced torque distribution within the coordinates.
2. However, the mass density is lower than in core-1 and consequently, the entropy in
the system is higher.
3. The C2 constant is lower in magnitude owing to higher spatial distribution of the
energy that is essentially lower in value as well when compared with the core-1
fundamentals.
4. The specific energy at the impacting points along the curvature at the boundary is
lower than in core-1 and hence the deflecting angle q2 for the energy shall also be
narrower and resulting in an acute angle as compared to q1.
5. Volume of air displaced is a function described in the equation :
Equation-2: y2 = f(x2) +C2 where x2 compares with x1 in the following manner:

5. a) Entropy is higher on account of lower packing density of the material defined by 35%
diameter and 40% mass; hence the spatial distribution of discrete particles representing
summation of mass is lower (assuming identical metallurgy and cross-sectional particle
diameter).
b) The entropy of the particles within the colliding medium in a dynamic motion shall be
higher causing a larger domain size for the coordinates described by an individual
particle – an important derivative in defining the consistency of air volume displaced and
the energy transmitted in the radial outwards direction from the composite nucleus.
c) Wider domain bounds of the particle coordinates also imply a higher linear curvature
of the impact.
The third layer of the composite cylinder is fundamentally oval in shape with 80% of the
conventional mass distributed in 70% of the diameter.
The center of gravity as defined by the coordinates of the composite nucleus is at 33%
level of the diameter of the oval structure implying that the structure balance is
achieving equilibrium at a lower position thereby lending stability.
The equation shall be y3 = f(x3) + C3
The constant C3 shall be different from the preceding ones described by C1 and C2in
the following aspects:
a) The energy curve shall be periodic in nature and not typically sinusoidal but shall
approximate an alternating parabola and an hyperbola with distinctly different

6. amplitudes as determined by the coordinates of the center of gravity and measure of
eccentricity angle a as in the illustration.
b) The packing density defined by 80% on a spatial distribution of 70% diameter shall
reduce entropy significantly and constrain the bounds of x3 thereby ensuring a well
defined parabola and an equally sharp outline for the hyperbola; so very vital to ensure
a controlled pattern in the air density of the displaced volume and also in the transmitted
energy patterns within each revolution of the eccentric bounds.
The final phase of the composite has 100% of the mass packed in 100% of the outer
diameter of the oval shell; thereby increasing the packing density to minimize particle
entropy and controlling the domain bounds as described by the equation:
Equation for the outer shell: y4 = f(x4) + C4
The conditions as explained in the equation are:

7. a) The CG of the composite nucleus is at 25% of the structural diameter (oval diameter
of the outer shell) implying a stabilizing point at a low equilibrium coordinates; in itself a
highly stable physical system is assured on a design perspective.
b) The bounds are well defined for x4 implying that the parabolic and hyperbolic curves
have sharp profiles and that the alternating high air volume is followed by a low
displaced volume thereby creating an air draft in the fiber field.
c) The measure of eccentricity as described by the angle a2 defines the amplitude of
the energy curve moving on an outward radial plane; hence in turn determining the
velocities of the displaced air volumes.
The above is an illustration that describes the operating layer of the carding zone and
the forces constituting the fiber field and has the following features as derivatives:
a) The operating layer in the conventional card is thicker and relatively uniform with the
normal changes over sharp curve domains.
In the design, the operating layer is reduced in thickness by the air draft caused by the
alternating parabola and hyperbola of the displacement trajectory of the air particles; a
derivative of the oval shape of the shell-3 and 4 of the cylinder composite.
b) The shear line is typically shoved up in the reference frame of the operating layer as
the wire sharpness depreciates on account of thrust load caused by the build-up of
fibers.

8. In the design, the energy density and the domain bounds as described by x3 and x4
progressively increase the curvature over which the normal changes; in effect the rate
of change of the normal is delayed causing the fibers to be gripped strongly on a wider
cluster length hereby effectively bringing down the coordinates of the line of shear; the
most important derivative of the design.
c) The conventional carding zone has the design issue of limited containment of the
fiber build-up in the operational layer owing to the transfer dynamics of the fibers to the
doffer zones. These are traditionally a function of the relative gap between the cylinder
and the doffer, the mutual concentricity of the two rotating elements. The geometric
positioning with respect to each other and the wire density of the cylinder with respect to
the doffer besides the profile and the tip hardening of the wires.
In the design, the oval structure of the shells in the composite and the varying intensities
that deflect the energy angles substantially from the original trajectory originating from
the nucleus and the significantly decreased rate of change of the normal of the radial
outwards energy impact contribute to waves of parabolic and hyperbolic profiles of the
displaced air. All of these contribute to a steady draft that contribute to a reduced
operational layer thickness, a distinctly lower coordinates for the line of shear and finally
the consistent heavy transfer of fibers onto the doffer.
The carding intensity of the design is significantly improves; in effect the dynamics of
yarn manufacturing is changed for good in a revolutionary manner.
The detailed mathematics at the curvature points for describing the surface
characteristics of the interfacing points between the shells progressively have been
avoided in this paper. That should come up for an expounding while collaborating with
the carding OEM.
This design is intended to change the dynamics of the yarn engineering process and
shall be the singularly most important factor in bringing in value in the textile chain in
terms of quality and product economy.
Finally, at the concluding stage, Blackstone Synergy intends to reach out to the
humanity through these innovations and try and make a difference in the lives of
humans affected by the economic crisis.
