Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
A chemiluminescent lighting device comprising a translucent container and contained therein: a. several inactive components of an active chemiluminescent mixture, b. barrier means separating said several components in several compartments within said container, said barrier means being breakable by impact with a striking means to combine said components, c. striking means for breaking said barrier means by impact therewith, d. a movable part that is movable within said container when said movable part is free and means restraining the free movement of said movable part within said container until the linear momentum of said movable part bearing against said restraining means exceeds a predetermined yield limit, whereupon said restraining means will yield and release said movable part for free movement, e. the said striking means, barrier means and movable part being located in relation to each other within said container so that when said movable part is released for free motion, within said tube said movable part will be impelled to bring together said barrier means and said striking means with impact sufficient to break said barrier means.
Claim 2
Dependent Claim
178 words
A chemiluminescent lighting device comprising a translucent container and contained therein: a. several inactive components of an active chemiluminescent mixture, b. barrier means separating said several components in several compartments within said container, said barrier means being breakable by impact with a striking means to combine said components, c. striking means for breaking said barrier means by impact therewith, d. a movable part that is movable within said container when said movable part is free and means restraining the free movement of said movable part within said container until the linear momentum of said movable part bearing against said restraining means exceeds a predetermined yield limit, whereupon said restraining means will yield and release said movable part for free movement, e. the said striking means, barrier means and movable part being located in relation to each other within said container so that when said movable part is released for free motion, within said tube said movable part will be impelled to bring together said barrier means and said striking means with impact sufficient to break said barrier means.
Claim 3
Dependent Claim
27 words
A chemiluminescent lighting device defined by claim 1 wherein said barrier means consists of a plurality of glass ampules each enclosing one of the respective inactive components.
Claim 4
Dependent Claim
22 words
A chemiluminescent lighting device defined by claim 2 wherein the defined movable part consists of at least one of said glass ampules.
Claim 5
Dependent Claim
28 words
A chemiluminescent lighting device defined by claim 3 wherein one of the defined glass ampules is contained within another of said ampules which is the defined movable part.
Claim 6
Dependent Claim
21 words
A chemiluminescent light device defined by claim 3 wherein the defined striking means consists of another one of said glass ampules.
Claim 7
Dependent Claim
16 words
A chemiluminescent device defined by claim 3 wherein the defined striking means is a steel ball.
Claim 8
Dependent Claim
26 words
A chemiluminescent device defined by claim 6 wherein one of said ampules is sealed inside the one of said glass ampule which is the moving part.
Claim 9
Dependent Claim
16 words
A chemiluminescent device defined by claim 2 wherein said movable part is also said striking means.
Claim 10
Dependent Claim
17 words
A chemiluminescent device defined by claim 8 wherein said movable part striking means is a steel ball.
Claim 11
Dependent Claim
28 words
A chemiluminescent device defined by claim 8 wherein said restraining means is a bag of breakable film fixed in said container and containing said movable part striking means.
