Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
A method for treating a skin burn aggravated by a hot, molten organic substance selected from the group consisting of tars, asphalts, bitumens and pitches adhering thereto, which comprises applying to the affected area a cooling solvent consisting essentially of a halogenated, short chain aliphatic acyclic hydrocarbon substituted by at least one atom of fluorine, bromine or chlorine, and having a boiling point of from 0° to 50° C. or mixtures thereof, to soften or dissolve and remove the organic substance while cooling the affected area without further injury to the burned skin.
Claim 2
Independent Claim
93 words
A method for treating a skin burn aggravated by a hot, molten organic substance selected from the group consisting of tars, asphalts, bitumens and pitches adhering thereto, which comprises applying to the affected area a cooling solvent consisting essentially of a halogenated, short chain aliphatic acyclic hydrocarbon substituted by at least one atom of fluorine, bromine or chlorine, and having a boiling point of from 0° to 50° C. or mixtures thereof, to soften or dissolve and remove the organic substance while cooling the affected area without further injury to the burned skin.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein the cooling solvent is ethyl chloride.
Claim 4
Dependent Claim
19 words
The method of claim 1 wherein the cooling solvent is a mixture of at least two of said hydrocarbons.
Claim 5
Independent Claim
105 words
A method for treating a skin burn aggravated by a hot, molten organic substance selected from the group consisting of tars, asphalts, bitumens and pitches adhering thereto, which comprises spraying the affected area with a volatile cooling solvent consisting essentially of a halogenated, short chain aliphatic acyclic hydrocarbon substituted by at least one atom of fluorine, bromine or chlorine, and having a boiling point of from 0° to 50° C. of mixtures thereof, to cool the burned skin and to soften or dissolve and remove the adhering substance without further substantial injury to the burned skin, and without substantial mechanical manipulation of the adhering substance.
Claim 6
Independent Claim
105 words
A method for treating a skin burn aggravated by a hot, molten organic substance selected from the group consisting of tars, asphalts, bitumens and pitches adhering thereto, which comprises spraying the affected area with a volatile cooling solvent consisting essentially of a halogenated, short chain aliphatic acyclic hydrocarbon substituted by at least one atom of fluorine, bromine or chlorine, and having a boiling point of from 0° to 50° C. of mixtures thereof, to cool the burned skin and to soften or dissolve and remove the adhering substance without further substantial injury to the burned skin, and without substantial mechanical manipulation of the adhering substance.
Claim 7
Dependent Claim
12 words
The method of claim 4 wherein the cooling solvent is ethyl chloride.
Claim 8
Dependent Claim
19 words
The method of claim 4 wherein the cooling solvent is a mixture of at least two of said hydrocarbons.
