Abstract

Abstract A method and apparatus for home production and application of fixed nitrogen fertilizer uses an arc discharge process to ionize nitrogen and oxygen and form nitrogen oxides. These nitrogen oxides are injected into water supplied by a garden hose to a yard or garden. The device is compact, economical and requires no raw materials except air to produce the fixed nitrogen. The device may operate on ordinary 60 cycles, 110 volt power.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 229 words
A device for producing nitrogen oxides by an arc discharge process and for injecting them into a water line supplying moisture to the yard or garden of a home, comprising: a cabinet, a source of electric power, transformer means in said cabinet, connected to said source of electric power, for supplying a high voltage potential, an arc discharge chamber, having an air intake opening and an exhaust opening, mounted in said cabinet, and including a chamber surface defining a first electrode, and a second electrode positioned centrally in said chamber, means for applying said high voltage potential to said first and second electrodes to cause arcing between said electrodes whereby nitrogen and oxygen in said chamber are ionized and nitrogen oxides are formed, transport means communicating with said exhaust opening of said arc discharge chamber for removing gases including said nitrogen oxides from said chamber, water fitting means mounted on the exterior of said cabinet and having input and output openings, said input opening communicating with a source of water and said output opening communicating with the water line distributing the fertilizer solution, and check valve means in said water fitting means for communicating with said transport means and for inserting said nitrogen oxides into the water flowing through said fitting means whereby a solution containing fixed nitrogen may be supplied to the yard or garden of a home.
Claim 2
Independent Claim 229 words
A device for producing nitrogen oxides by an arc discharge process and for injecting them into a water line supplying moisture to the yard or garden of a home, comprising: a cabinet, a source of electric power, transformer means in said cabinet, connected to said source of electric power, for supplying a high voltage potential, an arc discharge chamber, having an air intake opening and an exhaust opening, mounted in said cabinet, and including a chamber surface defining a first electrode, and a second electrode positioned centrally in said chamber, means for applying said high voltage potential to said first and second electrodes to cause arcing between said electrodes whereby nitrogen and oxygen in said chamber are ionized and nitrogen oxides are formed, transport means communicating with said exhaust opening of said arc discharge chamber for removing gases including said nitrogen oxides from said chamber, water fitting means mounted on the exterior of said cabinet and having input and output openings, said input opening communicating with a source of water and said output opening communicating with the water line distributing the fertilizer solution, and check valve means in said water fitting means for communicating with said transport means and for inserting said nitrogen oxides into the water flowing through said fitting means whereby a solution containing fixed nitrogen may be supplied to the yard or garden of a home.
Claim 3
Dependent Claim 12 words
The device of claim 1 in which said chamber surface is cylindrical.
Claim 4
Dependent Claim 46 words
The device of claim 1 in which said chamber surface is cone-shaped with said exhaust opening at the wider end of said chamber and in which a Jacob's Ladder arcing effect is created which tends to move the gases in said chamber toward said exhaust opening.
Claim 5
Dependent Claim 48 words
The device of claim 1 in which said transport means includes a transparent container mounted on the exterior of said cabinet through which said gases from said arc discharge chamber pass, whereby a visual indication is provided when nitrogen oxides are being produced in said arc discharge chamber.
Claim 6
Independent Claim 118 words
A method of home production and application of a fixed nitrogen fertilizer solution to the yard or garden of a home comprising the steps of: applying power from an electrical outlet to electrodes mounted in an arc discharge chamber such that a portion of the oxygen and nitrogen in the air in the chamber is ionized and nitrogen oxides are formed, transporting the gases in said chamber to a fixture connected between a garden hose and a water faucet and inserting said gases into the water as it flows from the faucet into the hose such that a fixed nitrogen solution is formed, and spraying said fixed nitrogen solution on the yard or garden with said garden hose.
Claim 7
Independent Claim 118 words
A method of home production and application of a fixed nitrogen fertilizer solution to the yard or garden of a home comprising the steps of: applying power from an electrical outlet to electrodes mounted in an arc discharge chamber such that a portion of the oxygen and nitrogen in the air in the chamber is ionized and nitrogen oxides are formed, transporting the gases in said chamber to a fixture connected between a garden hose and a water faucet and inserting said gases into the water as it flows from the faucet into the hose such that a fixed nitrogen solution is formed, and spraying said fixed nitrogen solution on the yard or garden with said garden hose.
Claim 8
Dependent Claim 35 words
The method of claim 5 wherein said step of transporting further includes the step of transporting said gases including nitrogen oxides through a transparent chamber whereby the formation of said nitrogen oxides is visually indicated.
Claim 9
Dependent Claim 24 words
The method of claim 5 further including the step of adding an alkaline substance to said water whereby said fixed nitrogen solution is neutral.
Claim 10
Dependent Claim 22 words
The method of claim 7 wherein said step of adding an alkaline substance includes the step of adding lime to said water.
Claim 11
Dependent Claim 23 words
The method of claim 7 wherein said step of adding an alkaline substance includes the step of adding potassium phosphate to said water.
Claim 12
Independent Claim 212 words
A device for producing nitrogen oxides by an arc discharge process and for adding them into a container of aqueous solution for home use, comprising: a cabinet, a source of electric power, transformer means in said cabinet, connected to said source of electric power, for supplying a high voltage potential, an arc discharge chamber, having an air intake opening and an exhaust opening, mounted in said cabinet, and including a chamber surface defining a first electrode, and a second electrode positioned centrally in said chamber, said chamber surface being cone shaped with said exhaust opening at the wider end of said chamber such that a Jacob's Ladder arcing effect is created which tends to move the gases in said chamber toward said exhaust opening, means for applying said high voltage potential to said first and second electrodes to cause arcing between said electrodes whereby nitrogen and oxygen in said chamber are ionized and nitrogen oxides are formed, a container of aqueous solution, and transport means communicating with said exhaust opening of said arc discharge chamber for removing gases including said nitrogen oxides from said chamber and transporting said gases to said container where said gases are inserted into the aqueous solution in said container whereby a solution containing fixed nitrogen is formed.
Claim 13
Independent Claim 212 words
