Abstract
Abstract A location marker having a first compartment containing at least one cloth streamer saturated with a chemiluminescent material and having a second compartment containing an activator composition for activating the chemiluminescent material, said first and second compartments being separated by a frangible barrier. A fuze section is provided having first and second triggering means whereby said first triggering means activates a gas-generating component to cause said activator composition to rupture said frangible barrier and saturate said at least one cloth streamer, and whereby said second triggering means actuates a pyrotechnic delay train which, in turn, ignites an explosive composition to eject said at least one cloth streamer from its compartment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A location marker comprising, a tubular container, at least one strip of cloth saturated with chemiluminescent material in one end of said container, a piston housing slidably mounted in said tubular container having a fluid compartment and a piston slidably mounted in said fluid compartment, a quantity of activator fluid in said fluid compartment, a frangible barrier closing one end of said fluid compartment, means for slidably moving said piston in said piston housing whereby movement of said piston causes said frangible barrier to break and saturate said at least one strip of cloth with activator fluid, and means for slidably moving said piston housing whereby movement of said piston housing ejects said at least one strip of cloth.
Claim 2
Dependent Claim
119 words
A location marker comprising, a tubular container, at least one strip of cloth saturated with chemiluminescent material in one end of said container, a piston housing slidably mounted in said tubular container having a fluid compartment and a piston slidably mounted in said fluid compartment, a quantity of activator fluid in said fluid compartment, a frangible barrier closing one end of said fluid compartment, means for slidably moving said piston in said piston housing whereby movement of said piston causes said frangible barrier to break and saturate said at least one strip of cloth with activator fluid, and means for slidably moving said piston housing whereby movement of said piston housing ejects said at least one strip of cloth.
Claim 3
Dependent Claim
63 words
A location marker as set forth in claim 1, wherein said at least one strip of cloth is saturated with chemiluminescent material comprised of 0.2 molar bis (2, 4, 5-trichloro-6-carbobutoxyhyenyl) oxalate, 0.003 molar 9, 10-bis (phenylethynyl) anthracene, 1 percent cyanacryl terpolymer, and 2 percent bis-(2-ethylhexyl) phthalate in benzene and wherein said activator fluid is comprised of 1.5 molar hydrogen peroxide in dimethyl phthalate.
Claim 4
Dependent Claim
73 words
A location marker as set forth in claim 1, wherein said means for slidably moving said piston includes a first firing pin, a primer, and a gas-generating pellet whereby triggering of said firing pin detonates said primer and ignites said gas-generating pellet and gas from same pellet moves said piston to rupture said frangible barrier whereby said at least one strip of cloth saturated with chemiluminescent material is activated by said activator fluid.
Claim 5
Dependent Claim
53 words
A location marker as set forth in claim 3, wherein said means for slidably moving said piston housing comprises a second firing pin, a primer, a pyrotechnic delay train, and an explosive pellet whereby detonation of said explosive pellet after said gas-generating pellet is ignited ejects said at least one strip of cloth.
Claim 6
Dependent Claim
45 words
A location marker as set forth in claim 4, wherein said first and second firing pins are maintained in a cocked position by a bore rider pin having means for preventing triggering of said firing pins while said location marker is within a launching tube.
