Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
54 words
A process for producing an excited compound of carbon radiating in the U.V. spectrum which comprises the steps of: a. reacting atomic carbon in an inert diluent gas with carbonyl sulfide to produce CS in the excited CS(a 3 π) molecular state, from which the CS molecule relaxes and emits radiation in the U.V.
Claim 2
Dependent Claim
54 words
A process for producing an excited compound of carbon radiating in the U.V. spectrum which comprises the steps of: a. reacting atomic carbon in an inert diluent gas with carbonyl sulfide to produce CS in the excited CS(a 3 π) molecular state, from which the CS molecule relaxes and emits radiation in the U.V.
Claim 3
Dependent Claim
54 words
A process for producing an excited compound of carbon radiating in the ultraviolet spectrum which comprises the step of: a. reacting atomic carbon in an inert diluent gas with carbonyl selenide to produce CSe in the excited CSe(a 3 π) molecular state, from which the CS molecule relaxes and emits radiation in the U.V.
Claim 4
Dependent Claim
54 words
A process for producing an excited compound of carbon radiating in the ultraviolet spectrum which comprises the step of: a. reacting atomic carbon in an inert diluent gas with carbonyl selenide to produce CSe in the excited CSe(a 3 π) molecular state, from which the CS molecule relaxes and emits radiation in the U.V.
Claim 5
Dependent Claim
100 words
A process for producing emission from an excited compound of carbon which comprises the steps of: a. forming atomic carbon in an inert diluent in a combustion zone; b. aerodynamically expanding the atomic carbon and diluent at supersonic velocity into an optical cavity; c. aerodynamically expanding carbonyl sulfide into the optical cavity at supersonic velocity; and d. reacting the atomic carbon and carbonyl sulfide according to the equation C(3P) + COS (X 1 Σ + ) → CS(a 3 π) + CO(X 1 Σ) + CO(X 1 Σ), thereby to cause emission of U.V. light from the excited carbonyl sulfide.
Claim 6
Dependent Claim
100 words
A process for producing emission from an excited compound of carbon which comprises the steps of: a. forming atomic carbon in an inert diluent in a combustion zone; b. aerodynamically expanding the atomic carbon and diluent at supersonic velocity into an optical cavity; c. aerodynamically expanding carbonyl sulfide into the optical cavity at supersonic velocity; and d. reacting the atomic carbon and carbonyl sulfide according to the equation C(3P) + COS (X 1 Σ + ) → CS(a 3 π) + CO(X 1 Σ) + CO(X 1 Σ), thereby to cause emission of U.V. light from the excited carbonyl sulfide.
Claim 7
Dependent Claim
