FG= Fresh gas inlet. BL=Bladder. D1, = Two position, three-way, detent directional control valves. D2 & D3 = Two position, three-way, spring return directional control valves. RF= Relief Valve. Note:- Arrow mark shows the direction of gas flow. Function of the System: When patient breaths out non-return valve, VO closes & VI opens, allowing the gas to flow in to bladder or in to ventilator, depending the position of DC valve D1. A “push pull knob” operates D1. At the same time gas also flows through DC valve D2, either to canister, CA or bye passed. The Valve D2 & D1 are connected to the Canister by pushpins, which presses the spring return spools to connect the gas passage to Canister. When canister is connected, gas flows through the tube to the bottom of canister and then comes out through holes provided in the tube. Now gas passes through a metallic mesh and comes in contact with soda lime. Soda lime absorbs CO2. Then remaining gas comes out through canister in to the valve D2. If the pressure is higher than the set value at relief valve, (RF) pressure is relieved. The relief valve, RF can set the pressure between 0- 100 mbars. The gas thus relieved to the set pressure, now mixed with fresh gas FG & passed to the patient through valve VI, when patient breaths-in. Construction of the system:- The system comprises of following sub-assembly. 1) Main Valve Assembly: Houses two spring return DC valves (D2&D3). The valves are operated by the pushpins when canister is fitted to the valve assembly. 2) Canister assembly: - The is a polycarbonate construction and contains soda lime and a metallic mesh. Gas enters the vessel at the top and travels to the bottom of the vessel and passes through soda lime and exit at the top. 3) Inlet Valve Assembly:- This assembly houses non-return valve through which patient breaths out. To this assembly is fitted the selector valve assembly. 4) Outlet Valve assembly:- This assembly houses a non-return valve through which patient breaths-in. A relief valve fitted to this assembly. There is a provision for the fresh gas to mix up with the breath-out gas. 5) Relief Valve Assembly:- This assembly houses a valve, which controls the pressure & relieves excess pressure developed by breath-out gas & by fresh gas entry. 6) Selector Valve Assembly:- This is a three-way valve, which connects either to the bladder or to the ventilator, so that the breath-out gas may pass to any one of them at a time. A knob will operate the valve by pulling & pushing. A detent will retain the valve at any one of the positions till other position is selected by pulling or pushing the knob. NOTE: The system should be installed vertically such that the non-return valves (Mica sheet valves) rests on valve seat by gravity, for proper functioning. Material of construction of the various components of the system is carbon steel, aluminum alloy & Polycarbonate. The non-return valves are of Mica or any suitable material having very light weight, because it has to operate on gas pressure developed by patient’s breathing. The intention of using aluminum alloy is to keep the weight of the assembly as low as possible. By adapting better quality of aluminum alloy, it is possible to change all most all carbon steel. Here below, certain aluminum alloys, which can be, substitute Carbon steel. Alternate Aluminum alloys: 1) USA Std, 2024 T3 Condition 2) USA Std 2024 The alloy 2024 is used in aircraft industries and to be imported. This is available in bars. The alloy has good strength and all the carbon steels in this application can be replaced, besides changing Al to IS:737, except Selector valve assembly & Main valve assembly spools The alloy 2014 is available in India. Here once again most of the carbon steels can be replaced. However, you have to examine cost implication before taking the decision.

Resistance Mechanism Purpose of the system: - The purpose of the system is to create a resistance while a person doing exercise. Basically the exercise here consists of a person sitting on his back resting on the back rest or his chest resting on the back rest. And then apply a force on the back rest that depends of the person’s stamina. Against this force a hydraulic resistance is created. The person thus swings on by applying the force from his chest or back. The swing is from 60 deg to 110 deg. The range of force applied is 30 – 300 lbs. The force is adjustable through resistance mechanism. Refer the drawings nos Construction & design of the system: The system has two portions. The machine & The resistance mechanism. The machine comprises of a chair of steel structure to which is attached a back rest arm. The basic machine is steel fabrication & not designed in this scope. However, the original is modified to incorporate resistance mechanism. This arm swings on the horizontal axis of an axle. The amount of swing is around 60 to 110 degrees. To the swing arm is connected a hydraulic cylinder that is actuated by oil pressure. The piston rod is fixed to the main housing. As the person swings the oil in the cylinder under pressure is pushed to rod end of cylinder via manifold assembly. A compression spring is housed inside cylinder. The function of the spring is to return the swing arm to start position in a controlled way. The hydraulic pressure is adjustable from around 0-80 bars . Maximum force a person can apply is around 300 lbs when maximum pressure set (around 80 bras) All other working methods & construction is clearly understood from the PDF drawings provided. It may or may not be necessary to modified relief valve range & compression spring depending on the function of prototypes. Manufacturing Process: The components’ drawings are provided with detail dimensions only for resistance mechanism. In case of machine dimensions are provided wherever changes are made.

STORAGE SYSTEM Purpose of the system:- The storage vessel is could be used by common man for residential purposes, to keep the food items , cooked or not cooked, grocery, cereals etc:afresh for longer time at an weather condition, without use of electric power. Basic principle: The air & moisture in the atmosphere is the main reason for spoilage of food & grocery. In the system, the air is flushed out from the container where items are stored & replaced by Nitrogen gas, which is an insert gas. The container is leak free & does not allow external enters the container. Nitrogen stays in the container longer time. Nitrogen is free from moisture. Construction of the system: - The system has four assemblies. N2 cylinder assembly, Gas inlet assembly, Container assembly & Bleed of f/ Valve assembly. Nitrogen cylinder is a rented/hired item. N2 is under pressure of 3000 psi. N2 gas pressure controlled by regulator. The regulator reduces the pressure to 00.5- 1.00 bar (gage). N2 gas at 1.0 bar enters the container through inlet assembly. The hand control valve is a shut off valve that can be closed when required. N2 gas entering the container at pressure of around 1.0 – 1.2 bars replaces the existing air inside the vessel. Since air is slightly heavier than N2 gas a bleed off/safety valve provided at the bottom flushes the air present in the container. The valve also acts as a safety valve. Air (& small quantity of N2) exists thru’ an orifice & makes a whistle. By whistle indication, the hand valve at inlet assembly is closed. This avoids excess N2 entering the cylinder. The container is an assembly of two co-axial cylinders one sliding in the other. The bottom cylinder is fixed & top one slide & maintains the leak free for the gas passage. The purpose is to vary the length of container, depending on the size of the object stored in it. The top sliding portion can be fixed between, six different position between the maximum & minimum position. Material of construction: - The container is made of polycarbonate of tensile strength of around 600 kg/cm2. The base & Rim of container is of aluminum. Sealing material is rubber of polyurethane. Fasteners are of high tensile steel. Valve, valve pin, is of carbon steel. At some places nylon/plastic is used. Depending on the availability, any suitable material could be used. Testing of the prototype: All the joints are checked for gas leakage. Soap bubble method may be used. All the components to be checked for their geometrical conformity. The bleed off/safety valve should open at around 1.0 to 1.1 bars. While closing it should come down slowly. The valve operated by weight of valve housing & valve. Hence it is necessary the container should be installed in the vertical position.
