FIELD OF THE INVENTION
The present invention relates to a system and a method for extraction of the one or more orings,
and more specifically, the present invention relates to the system and the method for
extraction of the one or more o-rings from the gas cylinder by one or more primary
pneumatic drives and one or more secondary pneumatic drives.
BACKGROUND OF THE INVENTION
The cooking gas cylinders or liquefied petroleum gas cylinders are used for various
household needs as well as commercial requirements. The liquefied petroleum gas is used
for cooking in many countries for economic reasons, for convenience or because it is the
preferred fuel source. The liquefied petroleum gas is the most common cooking fuel in
urban areas of India and Brazil. The liquefied petroleum gas is odorless and colorless gas,
but it is mixed with other gases to make it detectable during any leakage. The liquefied
petroleum gas is supplied in cylinders known as the gas cylinders or the liquefied petroleum
gas cylinder. In order to maintain the seal in the valve of the gas cylinders, variety of
components are used which prevent the leakage of the liquefied petroleum gas. The most
commonly used component is the o-ring. The o-ring is placed in the valve of the cylinder.
The o-ring provides a leakage proof seal. The o-ring gets loose or gets damaged with time.
This increases the chances of gas leakage which further leads to burning incidents or
accidents. To avoid this situation the o-ring is replaced every time or when needed when
the gas cylinder is refilled in order to minimize the chances of gas leakage. The
replacement of the o-ring is done manually which is very time consuming, costly and can
damage or scratch the cylinder. It is also possible to missing of replacing o-ring manually
2
which can cause accidents. So, by implementing automation, possibility of missing is ruled
out.
US4813120A discloses a tool for extracting seated o-ring from a confining annular
indentation having an elongated o-ring prying section coupled to a handle, the prying
section including a curved terminal portion affixed to the handle, a recess formed between
the curved terminal portion and the handle to deter interference between the tool and
shoulder portions of the indentation during prying of the o-ring out of the indentation upon
rocking of the handle.
US5564175A discloses a tool for use in removing the o-ring seal member from a grooved
surface includes an elongated handle portion and a head portion having a rounded tip
portion. The tip portion is inserting able into the grooved surface and underneath the o-ring
seal member so as to pry manually and lift upwardly the same in order to remove the o-ring
seal member.
US4330917A discloses a hand-held tool to use in extracting ring seats from housings such
as small engine carburetor needle inlet valves is disclosed.
US3577848A discloses a tool for extracting o-ring from grooves which are recessed from
the mouth of an opening.
The present invention is an advancement of already existing systems in this field of
invention. The drawbacks of already existing systems are that all the already existing
systems are manual, they need more time and the process is tedious. The existing invention
used for removal of the one or more o-rings can cause scratches on the cylinder. None of
the existing technology uses such system and method that is disclosed in the present
invention. The present invention effectively overcomes the deficiencies in the prior art.
Hence there is a need for the present invention.

C; B and C; A, B and C”. An exception to this definition will occur only when a
combination of elements, functions, steps or acts are in some way inherently mutually
exclusive.
As used herein, the term "one or more" generally refers to, but not limited to, singular as
well as plural form of the term.
The drawings featured in the figures are for the purpose of illustrating certain convenient
embodiments of the present invention, and are not to be considered as limitation thereto.
Term “means” preceding a present participle of an operation indicates a desired function
for which there is one or more embodiments, i.e., one or more methods, devices, or
apparatuses for achieving the desired function and that one skilled in the art could select
from these or their equivalent in view of the disclosure herein and use of the term “means”
is not intended to be limiting.
As used herein, the term "pneumatic drive" generally refers to, but not limited to device
system which uses gas or pressurized air. Pneumatic systems used extensively
in industry are commonly powered by compressed air or compressed inert gases. A
centrally located and electrically powered compressor powers cylinders, air motors, and
other pneumatic devices. A pneumatic system controlled through manual or
automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer
alternative to electric motors and actuators.
As used herein, the term "pneumatic" generally refers to, but not limited to, a branch
of engineering that makes use of gas or pressurized air. The pneumatic can be referred to as
a type of power that operates a motor or to a type of tire or wheel. The pneumatics is a
11
means of transmitting energy by use of compressible air. The air is stored in a receiver and
used to create power by use of control valves. The quantity of the desired power can also be
controlled by the valves.
As used herein, the term "energy" generally refers to, but not limited to, measure of the
ability of a body or system to do work or produce a change, expressed usually in joules or
kilowatt hours (kWh). The form of energy includes both potential and kinetic energy.
As used herein, the term "actuator" generally refers to, but not limited to a type
of motor that is responsible for moving or controlling a mechanism or system. The actuator
is operated by a source of energy, typically electric current, hydraulic fluid pressure, or
pneumatic pressure, and converts that energy into motion. The actuator is a type of motor
that is responsible for moving or controlling a mechanism or system. The actuator is the
mechanism by which a control system acts upon an environment. The control system can
be simple, such as a fixed mechanical or electronic system, software-based, such as, e.g. a
printer driver, robot control system, a human, or any other input. A pneumatic actuator
converts energy formed by vacuum or compressed air at high pressure into either linear or
rotary motion. Pneumatic energy is desirable for main engine controls because it can
quickly respond in starting and stopping as the power source does not need to be stored in
reserve for operation. The pneumatic actuators enable considerable forces to be produced
from relatively small pressure changes. These forces are often used with the valve to move
diaphragms to affect the flow of liquid through the valve.
As used herein, the term "regulator" generally refers to, but not limited to, a device which
has the function of maintaining a designated characteristic. The regulators perform the
activity of managing or maintaining a range of values in a machine. The measurable
property of a device is managed closely by specified conditions or an advance set value; or
it can be a variable according to a predetermined arrangement scheme. The regulators can
be used generally to connect any set of various controls or devices for regulating or
12
controlling items or objects. Regulators can be designed to control anything from gases or
fluids, to light or electricity. The speed can be regulated by electronic, mechanical, or
electro-mechanical means.
As used herein, the term "working fluid" generally refers to, but not limited to, a
pressurized gas or liquid that actuates a machine. Examples include steam in a steam
engine, air in a hot air engine and hydraulic fluid in a hydraulic motor or hydraulic cylinder.
More generally, in a thermodynamic system, the working fluid is a liquid or gas that
absorbs or transmits energy.
A gaseous or liquid substance by means of which an energy conversion is accomplished to
obtain mechanical work (in engines), cold (in refrigerating machines), or heat (in heat
pumps). The most common working fluids are steam, used in steam turbines and steam
engines; the combustion products of organic fuels, used in internal combustion engines and
gas turbines; water and other liquids, used in hydraulic engines; air, used in the pneumatic
engines; and refrigerants, used in refrigerating machines. A rocket propellant is also called
a working fluid.
As used herein, the term "hollow cylinder" generally refers to, but not limited to, an
enclosing shell, tube, or surrounding material. The hollow cylinders are the major structural
component of a well. The casing is needed to maintain bore whole stability, Prevent
contamination of water sands, Isolate water from producing formations, control well
pressures during drilling, production, and work over operations. The hollow cylinders
provide locations for the installation of blowout preventers, wellhead equipment,
production packers and production tubing.
As used herein, the term “flange” generally refers to, but not limited to, an external or
internal ridge, or rim, for strength, as the flange of an iron beam such as an I-beam or a Tbeam;
or for attachment to another object, as the flange on the end of a pipe, a steam

13
Thus flanged wheels are wheels with a flange on one side to keep the wheels from running
off the rails. The term "flange" is used for a kind of tool used to form flanges. Pipes with
flanges can be assembled and disassembled easily.
As used herein, the term “base cone” generally refers to, but not limited to, a threedimensional
geometric shape that tapers smoothly from a flat base (frequently, though not
necessarily, circular) to a point called the apex or vertex.
As used herein, the term “base” generally refers to, but not limited to, the lowest part or
edge of something, especially the part on which it rests or is supported.
As used herein, the term “vane” generally refers to, but not limited to, a broad blade
attached to a rotating axis or wheel which pushes or is pushed by wind or water and forms
part of a machine or device such as a windmill, propeller, or turbine.

As used herein, the term “spring” generally refers to, but not limited to, an elastic object
used to store mechanical energy. The springs are usually made out of spring steel. There are
a large number of the spring designs; in everyday usage the term often refers to coil
springs. When a coil spring is compressed or stretched slightly from rest, the force it exerts
is approximately proportional to its change in length. The rate or spring constant of a spring
is the change in the force it exerts, divided by the change in deflection of the spring. That
is, it is the gradient of the force versus deflection curve. An
extension or compression spring has units of force divided by distance, for example lbf/in
or N/m.
As used herein, the term “fluid” generally refers to, but not limited to, a substance that
continually flows under an applied shear stress. The fluids are a subset of the phases of
matter and include a liquid, a gas, a plasma and to some extent a plastic solids. The fluids
can be defined as substances that have zero shear modulus. Although the term "fluid"
includes both the liquid and the gas phases, "the fluid" is often used as a synonym for "the
liquid".
As used herein the term “hook” generally refers to, but not limited to, a piece of metal or
other hard material curved or bent back at an angle, for catching hold of or hanging things
on. The hook is of different type, but not limited to a bagging hook, a grappling hook, a
hook with a latch, a mail hook, a cabin hook, a cargo hook, a meat hooks and a fish hook.
15
As used herein, the term “gas cylinder” generally refers to, but not limited to, a pressure
vessel used to store gases at above atmospheric pressure. A high-pressure gas cylinder is
also called bottles. The gas cylinders are made of but limited to, steel, composite materials,
polymers PET, copper, and carbon fiber.
As used herein, the term “pneumatic cylinder” generally refers to but not limited, to
a mechanical devices which use the power of compressed gas to produce a force in a
reciprocating linear motion. The pneumatic cylinders are mechanical devices which
produce force, often in combination with movement, and are powered by compressed gas
(typically air). To perform their function, the pneumatic cylinders impart a force by
converting the potential energy of compressed gas into kinetic energy. This is achieved by
the compressed gas being able to expand, without external energy input, which itself occurs
due to the pressure gradient established by the compressed gas being at a greater pressure
than the atmospheric pressure. This air expansion forces a piston to move in the desired
direction. Once actuated, compressed air enters into the tube at one end of the piston and,
hence, imparts force on the piston.
As used herein, the term “cylinder” generally refers to but not limited to, a one of the most
basic curvilinear geometric shapes, the surface formed by the points at a fixed distance
from a given straight line, the axis of the cylinder. The solid enclosed by this surface and by
two planes perpendicular to the axis is also called a cylinder. The surface area and
the volume of a cylinder have been known since deep antiquity.
As used herein, the term “liquefied petroleum gas” refers to but not limited to,
flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking
equipment, and vehicles. Liquefied petroleum gas is increasingly used as an aerosol
propellant and a refrigerant, replacing chlorofluorocarbons in an effort to reduce damage to
the ozone layer. When specifically used as a vehicle fuel it is often referred to as auto gas.
.
16
As used herein, the term “o-ring” refers to but not limited to a packing, or a toric joint, is a
mechanical gasket in the shape of a torus; it is a loop of elastomeric with a round crosssection,
designed to be seated in a groove and compressed during assembly between two or
more parts, creating a seal at the interface. The one or more o-rings may be used in static
applications or in dynamic applications where there is relative motion between the parts
and the one or more o-rings. Dynamic examples include rotating pump shafts and hydraulic
cylinder pistons. The one or more o-rings are one of the most common seals used in
machine design because they are inexpensive, easy to make, and reliable and have simple
mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.
The one or more o-rings is made of but not limited to a butadiene rubber, a butyl rubber, a
chlorosulfonated polyethylene, an ethylene propylene rubber, a nitrile rubber, a silicone
rubber, a thermoplastic elastomer, a polytetrafluoroethylene, a perfluoroelastomer, a
polyisoprene, a fluoroelastomer, an epichlorohydrin. The pneumatic cylinders are
mechanical devices which produce force. The o-ring seal is a means of closing off a
passageway and preventing an unwanted loss or transfer of fluid. The classic o-ring seal
consists of two elements, the one or more o-ring itself, and a properly designed gland or
cavity to contain the elastomeric material. Prevention of the fluid loss or transfer may be
obtained by several methods: welding, soldering, brazing or the yielding of a softer material
wholly or partially confined between two mating surfaces. The elastomer is contained in the
gland and forced to flow into the surface imperfections of the glands and any clearance
available to it, creating a condition of clearance and thus affecting a positive block to the
fluid being sealed. The pressure which forces the one or more o-rings to flow is supplied by
mechanical pressure or generated by proper gland design and material selection and by
system pressure transmitted by the fluid itself to the seal element. In fact, the classic o-ring
seal may be said to be pressure assisted in that the more system pressure, the more effective
the seal, until the physical limits of the elastomer are exceeded and the one or more o-rings
begins to extrude into the clearance gap This condition can usually be avoided by proper
gland design and material selection.
17
As used herein, the term “seal” refers to but not limited to, a device that helps join systems
or mechanisms together by preventing leakage (e.g. in a plumbing system),
containing pressure, or excluding contamination. The effectiveness of a seal is dependent
on adhesion in the case of sealants and compression in the case of gaskets. In mechanical
seals main friction happens in the axial direction, between faces (seal rings) lapped to a
high precision. A wear is compensated in axial direction by the springs or bellows. The
technology of mechanical seals is by no means new. It has been accepted in many
industries for decades. In most cases it has proven to be effective and reliable. The range of
designs and materials extends from home heating circulating pumps to 380C hot
hydrocarbons pumps at oil refineries or to 100 bar crude oil transfer pumps, costing from
10 dollars to 20,000 dollars and even more, depending on the industry and country.
As used herein, the term “valve” refers to but not limited to a device that regulates, directs
or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening,
closing, or partially obstructing various passageways. The valve are technically fittings, but
are usually discussed as a separate category. In an open valve, fluid flows in a direction
from higher pressure to lower pressure. The word is derived from the Latin valva, the
moving part of a door, in turn from volvere, to turn, roll.
As used herein, the term “method” refers to but not limited to, a particular procedure for
accomplishing or approaching something.
As used herein, the term “groove” refers to but not limited to, is a long and narrow
indentation built into a material, generally for the purpose of allowing another material or
part to move within the groove and be guided by it.
As used herein, the term “pneumatic energy” refers to but not limited to, the power related
to pressurized air. The pressure can be relatively static (such as surge tanks or pressure
tanks) or in motion through tubing or hoses.
18
As used herein, the term “plate” refers to a flat, thin piece of metal circular or quadrilateral
in shape having thickness ranging from 1mm to 25mm or more.
As used herein, the term “lever” refers to a rigid bar resting on a pivot at one end and other
is free, and used to move in rocking motion when torque is applied at pivoted end.
As used herein, the term “nut” refers to a small flat piece of metal or other material,
typically square or hexagonal, with a threaded hole through it for screwing on to different
type of bolt, but not limited to set screw, socket screw, eye bolt, hex bolt and carriage bolt.
Nuts are of different type, but not limited to, wing nut, coupling nut, slotted nut and heavy
hex.
As used herein, the term “bolt” refers to a large cylindrical metal pin with thread on its
periphery and flat head at one end.
As used herein, the term “set screw” refers to a type of bolt with thread on its periphery but
without flat head at one end so that set screw is being able to be screwed at both ends.
As used herein, the term “coupling” refers to a type of long nut that are being used to
connect pieces of threaded rod or fasteners.
As used herein, the term “hinge joint” refers to a mechanical bearing that connects two
solid objects, typically allowing only a limited angle of rotation between them. Two objects
connected by an ideal hinge joint rotate relative to each other about a fixed axis of rotation.
