System for recycling helium

1 . A system, comprising:

a bursting chamber with a re-sealable lid and a vent;

a bursting mechanism disposed inside the bursting chamber;

wherein the bursting chamber is in fluid communication with a compressor;

wherein the bursting chamber has a piston with at least one seal, the seal creating a vacuum-tight and gas-tight seal around the piston;

wherein the piston is operatively connected to a hydraulic cylinder and the piston is moveable by the hydraulic cylinder from a retracted position to an extended position; and

wherein moving the piston from the retracted position to the extended position forces helium from burst balloons out of the bursting chamber and to the compressor; and

wherein an output of the compressor is in fluid communication with an evacuation valve and a control valve;

wherein when the evacuation valve is opened and the control valve is closed the compressor evacuates the air from the bursting chamber; and

wherein when the evacuation valve is closed and the control valve is opened, and the bursting mechanism is activated, compressed helium gas recovered from balloons burst in the bursting chamber flows through the control valve into a helium storage tank.

2 . The system of claim 1 , wherein the bursting chamber is able to structurally withstand a vacuum of at least 29.9 inches of mercury.

3 . The system of claim 1 , wherein the system is either manually controlled or automatically controlled.

4 . The system of claim 1 , wherein the bursting chamber is provided with a pressure indicator.

5 . The system of claim 1 , wherein the compressor is selected from the group comprising positive displacement compressors and dynamic compressors.

6 . The system of claim 1 , wherein the compressor is cooled by air, water or other fluids or is un-cooled.

7 . The system of claim 1 , wherein the compressor has a single stage or has multiple stages.

8 . The system of claim 1 , wherein two or more compressors are operated in series to achieve a desired final pressure of helium in the helium storage tank.

9 . The system of claim 1 , wherein the compressor is manually-controlled or is electrically-actuated.

10 . The system of claim 1 , wherein the evacuation valve and the control valve are manually-controlled valves or are electrically actuated valves.

11 . The system of claim 1 , wherein the control valve is provided with a one-way check valve fitting to prevent a backflow of compressed helium gas out of the helium storage tank.

12 . The system of claim 1 , wherein recycled helium collected in the helium storage tank is used in a way selected from the group comprising: the recycled helium is used as-is to fill new balloons; the recycled helium is blended with virgin helium and then used to fill new balloons; the recycled helium is purified and/or compressed to a higher pressure and the resultant purified and/or compressed helium is used for filling balloons; the recycled helium is re-purposed for a use other than filling balloons.

13 . The system of claim 1 , wherein the bursting mechanism disposed inside the bursting chamber comprises:

a plurality of springs having a first end and a second end;

a platform with spikes secured to the first end of the springs;

said springs further anchored at the second end to an interior surface of the bursting chamber;

a trigger mechanism disposed at the bottom of the bursting chamber which allows for the selective triggering of release of the platform;

wherein when said trigger mechanism is released, the springs draw the platform up toward an underside of the lid of the bursting chamber, thereby impinging any balloons disposed between the lid and the platform on the spikes and bursting said balloons.

14 . The system of claim 1 , wherein the bursting mechanism disposed within the bursting chamber comprises:

a spring having a first end and a second end;

a platform with spikes secured to the first end of the spring;

said spring further anchored at the second end to an interior surface of the bursting chamber;

said platform connected by a hinge to the interior surface of the bursting chamber;

a trigger mechanism disposed at the bottom of the bursting chamber which allows for the selective triggering of release of the platform;

wherein when said trigger mechanism is released, the spring draws the platform up toward a side wall of the bursting chamber and through a rotational arc of the hinge, thereby impinging any balloons disposed between the side wall and the platform on the spikes and bursting said balloons.

15 . The system of claim 1 , wherein the bursting mechanism disposed within the bursting chamber comprises:

a platform with spikes;

a plurality of tracks anchored to an interior surface of the bursting chamber, wherein the platform is configured to ride in the plurality of tracks;

a weight;

a trigger mechanism disposed at the top of the bursting chamber which allows for the selective triggering of release of the platform;

wherein when said trigger mechanism is released, the platform and weight are pulled by gravity down the tracks, thereby impinging any balloons disposed between the platform and a bottom surface of the bursting chamber on the spikes and bursting said balloons.

16 . The system of claim 1 , wherein the bursting mechanism disposed within the bursting chamber comprises:

a platform with spikes, said platform connected by a hinge to an interior surface of the bursting chamber;

a weight;

a trigger mechanism disposed at the top of the bursting chamber which allows for the selective triggering of release of the platform;

wherein when said trigger mechanism is released, the platform and weight are pulled down by gravity and swing through a rotational arc of the hinge, thereby impinging any balloons disposed between the platform and the side surface of the bursting chamber on the spikes and bursting said balloons.

17 . The system of claim 1 , wherein the bursting mechanism disposed within the bursting chamber comprises:

a platform with spikes;

said platform connected to a hydraulic cylinder secured to the bottom of the bursting chamber;

wherein the user activates the hydraulic cylinder driving the platform up toward the underside of the lid of the bursting chamber thereby impinging any balloons disposed between the lid and the platform on the spikes and bursting said balloons.

18 . The system of claim 1 , wherein the bursting mechanism disposed within the bursting chamber comprises:

a motor connected via a shaft passing through the lid of the bursting chamber to a set of rotating blades disposed within the bursting chamber; wherein the user activates the motor, which drives the rotating blades, bursting any balloons in the bursting chamber.

19 . The system of claim 1 , wherein the bursting mechanism disposed within the bursting chamber comprises:

an array of resistive heating elements in electrical communication with a controller outside the bursting chamber;

wherein a user activates the controller to turn on the resistive heating elements and when balloons come in contact with the resistive heating elements they are melted, thereby bursting said balloons.
