Abstract
Abstract An apparatus and method for converting heat from the combustion of fuel into visible and colored light by providing a plurality of radiators which are thermally excitable to emit visible lights, positioning the radiators in parallel in-line relationship so that the light emitted by the initial radiator passes through and is modified by subsequent radiators, and means for controllably heating each of said radiators to predetermined temperature levels by the combustion of fuel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
AN APPARATUS FOR CONVERTING HEAT FROM THE COMBUSTION OF FUEL INTO VISIBLE LIGHTS HAVING PREDETERMINED AND CONTROLLABLE COLORS COMPRISING: AN OPAQUE HOUSING HAVING AN OPENING AT ONE END THEREOF FOR PASSAGE OF LIGHT OUT OF SAID HOUSING, A PLURALITY OF RADIATORS THERMALLY EXCITABLE TO EMIT VISIBLE COLORED LIGHTS DISPOSED IN SAID HOUSING, SAID PLURALITY OF RADIATORS INCLUDING A FIRST RADIATOR COMPRISING A CERIA-THORLA MANTLE AND A SECOND RADIATOR COMPRISING A COLORED TRANSPARENT OR TRANSLUCENT FILTER CAPABLE OF WITHSTANDING HIGH TEMPERATURES POSITIONED IN OPTICALLY COUPLED RELATIONSHIP TO SAID FIRST RADIATOR SO THAT LIGHT EMITTED BY SAID FIRST RADIATOR PASSES THROUGH SAID SECOND RADIATOR BEFORE EMERGING FROM THE OPENING IN SAID HOUSING, AND MEANS FOR HEATING EACH OF SAID RADIATORS TO PREDETERMINED TEMPERATURE LEVELS TO PRODUCE COLORED LIGHTS VISIBLE AT SAID OPENING, SAID HEATING MEANS INCLUDING NATURAL GAS INLET MEANS AND MEANS FOR IGNITING SAID NATURAL GAS, AND MEANS FOR REGULATING THE FLOW OF NATURAL GAS INTO SAID APPARATUS.

Claim 3
Dependent Claim
15 words
An apparatus as in claim 1 wherein said second radiator is a green glass filter.
Claim 4
Dependent Claim
15 words
An apparatus as in claim 1 wherein said second radiator is a blue glass filter.
Claim 5
Dependent Claim
94 words
A process for obtaining controllable colored lights which comprises a. heating a first, ceria thoria mantle fabric radiator to a predetermined temperature by combustion of natural gas to emit visible light; b. heating a colored transparent or translucent filter capable of withstanding high temperatures and defining a second radiator to a predetermined temperature to emit visible light; and c. passing the light from the first mantle fabric radiator through the second radiator to obtain a predetermined resultant colored light; and d. selecting the resultant light color by controlling the temperature of said second radiator.
Claim 6
Dependent Claim
94 words
A process for obtaining controllable colored lights which comprises a. heating a first, ceria thoria mantle fabric radiator to a predetermined temperature by combustion of natural gas to emit visible light; b. heating a colored transparent or translucent filter capable of withstanding high temperatures and defining a second radiator to a predetermined temperature to emit visible light; and c. passing the light from the first mantle fabric radiator through the second radiator to obtain a predetermined resultant colored light; and d. selecting the resultant light color by controlling the temperature of said second radiator.
Claim 7
Dependent Claim
20 words
The process of claim 4 including passing the light from said first mantle fabric radiator through a green glass filter.
Claim 8
Dependent Claim
24 words
The process of claim 5 wherein the temperature of said green glass filter is selectively controlled to obtain red, yellow and green colored lights.
Claim 9
Dependent Claim
20 words
The process of claim 4 including passing the light from said first mantle fabric radiator through a blue glass filter.
Claim 10
Dependent Claim
23 words
The process of claim 4 including the step of burning natural gas to heat said first and second radiators to said predetermined temperatures.
