Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
65 words
A pyrotechnic composition for the generation of a non-toxic, non-flammable and essentially smokeless inflating gas for an inflatable occupant safety restraint, said composition comprising, in approximate weight percent based on the total weight of the composition, (a) 1 to 10% of a high density homopolymer of ethylene, having a density of about 0.92 to 0.97 at 23° C. as determined by ASTM Method D 792;
Claim 2
Dependent Claim
65 words
A pyrotechnic composition for the generation of a non-toxic, non-flammable and essentially smokeless inflating gas for an inflatable occupant safety restraint, said composition comprising, in approximate weight percent based on the total weight of the composition, (a) 1 to 10% of a high density homopolymer of ethylene, having a density of about 0.92 to 0.97 at 23° C. as determined by ASTM Method D 792;
Claim 3
Dependent Claim
46 words
(b) 20 to 30% of a coolant selected from the group consisting of calcium hydroxide, magnesium hydroxide, calcium carbonate and magnesium carbonate, and (c) 60 to 79% of an inorganic oxidizer selected from the group consisting of sodium chlorate, potassium chlorate, sodium perchlorate and potassium perchlorate.
Claim 4
Dependent Claim
46 words
(b) 20 to 30% of a coolant selected from the group consisting of calcium hydroxide, magnesium hydroxide, calcium carbonate and magnesium carbonate, and (c) 60 to 79% of an inorganic oxidizer selected from the group consisting of sodium chlorate, potassium chlorate, sodium perchlorate and potassium perchlorate.
Claim 5
Dependent Claim
12 words
The composition of claim 1 wherein the inorganic oxidizer is sodium chlorate.
Claim 6
Dependent Claim
11 words
The composition of claim 2 wherein the coolant is calcium hydroxide.
Claim 7
Dependent Claim
15 words
The composition of claim 3 wherein about 0.5 to 1.5 wt.% carbon black is present.
Claim 8
Dependent Claim
28 words
The compositon of claim 3 wherein the ethylene homopolymer--and the period following "present" has been changed to--in an amount of from about 3 to 5 wt.% is present.
