Abstract
Abstract A display device and method wherein natural or other combustible gas is mixed with water as water is ejected from a special mixing chamber to cause the gas to be trapped and encapsulated in bubbles suspended in the water stream so that when the mixture of gas and water breaks over by loss of momentum and gravity the bubbles will break, releasing the combustible gas which is ignited and provides a flame at the point where the water breaks over. By varying the pressure of the water ejected from the head, the encapsulated gas may be released at selected heights and is released over a greater area.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A method of producing a display device comprising the provision of an enclosed mixing chamber having a perforated member across the outlet of the chamber; the simultaneous admission of dispersed water and dispersed combustible gas under pressure into the chamber; the dispersal of said water in said chamber as the gas is mixed therewith to continuously form bubbles of encapsulated gas in the chamber; the ejection of a stream of bubbles from the chamber through the perforated member under pressure; and burning the gas as the bubbles burst in the atmosphere.
Claim 2
Independent Claim
91 words
A method of producing a display device comprising the provision of an enclosed mixing chamber having a perforated member across the outlet of the chamber; the simultaneous admission of dispersed water and dispersed combustible gas under pressure into the chamber; the dispersal of said water in said chamber as the gas is mixed therewith to continuously form bubbles of encapsulated gas in the chamber; the ejection of a stream of bubbles from the chamber through the perforated member under pressure; and burning the gas as the bubbles burst in the atmosphere.
Claim 3
Dependent Claim
13 words
The method called for in claim 1 wherein the ejection pressure is varied.
Claim 4
Dependent Claim
19 words
The method called for in claim 1 wherein the stream is ejected in a vertical column from the chamber.
Claim 5
Dependent Claim
18 words
The method called for in claim 1 wherein the stream is ejected laterally and arcuately from the chamber.
Claim 6
Dependent Claim
16 words
The method called for in claim 1 wherein the stream breaks over in an annular pattern.
Claim 7
Dependent Claim
93 words
In a device of the class described, a water supply conduit, a hollow housing attached to the water supply conduit; a manifold attached about the housing providing an annular passage thereabout; spaced ports through the wall of the housing communicating between the interior of the housing and the annular passage; a combustible gas supply line communicating with the annular passage; perforated water dispersal means between the water supply conduit and the interior of the housing; a restricted outlet passage from the housing and perforated means across the restricted outlet passage from the housing.
Claim 8
Dependent Claim
93 words
In a device of the class described, a water supply conduit, a hollow housing attached to the water supply conduit; a manifold attached about the housing providing an annular passage thereabout; spaced ports through the wall of the housing communicating between the interior of the housing and the annular passage; a combustible gas supply line communicating with the annular passage; perforated water dispersal means between the water supply conduit and the interior of the housing; a restricted outlet passage from the housing and perforated means across the restricted outlet passage from the housing.
Claim 9
Dependent Claim
49 words
The combination called for in claim 6 wherein the dispersal means comprises a perforated plate across the conduit passage entrance into the housing; and a thimble above the plate having a perforated bottom wall and passages through the sidewall communicating with the ports through the wall of the housing.
Claim 10
Dependent Claim
23 words
The combination called for in claim 7 wherein the perforated means comprises a plurality of screens above the thimble, across the outlet passage.
Claim 11
Independent Claim
118 words
A method of producing a display device comprising, providing a mixing chamber having a water inlet passage and a water outlet passage; admitting water through substantially vertically disposed perforations into the mixing chamber through the water inlet passage to form dispersed streams of water; admitting combustible gas through substantially horizontally disposed perforations in the sidewall of the mixing chamber to form dispersed streams of combustible gas impinging with the dispersed streams of water to continuously form bubbles of encapsulated gas in the mixing chamber; ejecting the bubbles of encapsulated gas through the water outlet passage of the mixing chamber into the atmosphere, forming a stream of bubbles; and burning the gas as the bubbles burst in the atmosphere.
