Abstract
Abstract This invention relates to an automatically activated delay action battery, containing an electrolyte, sealed in an ampoule of novel design. This novel ampoule comprises a perforated container whose perforations are sealed with removable plugs, and a slidably mounted sleeve with misaligned holes over the container restraining the plugs. Set-back force slides the sleeve to align the holes with the perforations and centrifugal force causes the electrolyte to dislodge the plugs and flow into contact with the plates to activate the battery.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
A delay action battery adopted for use in spin stabilized projectiles comprising: a casing; a closed ampoule containing liquid electrolyte and axially mounted in said casing and having a perforated wall wherein said perforations are sealed with removable plugs; a plurality of cell plates mounted in a chamber between said ampoule and said casing; and a slidably mounted perforated sleeve over said ampoule wall restraining said removable plugs, said sleeve adopted to slide rearwardly by setback force of projectile to align perforations in said sleeve and said ampoule wall, thereby permitting said electrolyte, by centrifugal force due to projectile spin to displace said removable plugs and flow into said chamber to activate the battery.
Claim 2
Dependent Claim
114 words
A delay action battery adopted for use in spin stabilized projectiles comprising: a casing; a closed ampoule containing liquid electrolyte and axially mounted in said casing and having a perforated wall wherein said perforations are sealed with removable plugs; a plurality of cell plates mounted in a chamber between said ampoule and said casing; and a slidably mounted perforated sleeve over said ampoule wall restraining said removable plugs, said sleeve adopted to slide rearwardly by setback force of projectile to align perforations in said sleeve and said ampoule wall, thereby permitting said electrolyte, by centrifugal force due to projectile spin to displace said removable plugs and flow into said chamber to activate the battery.
Claim 3
Dependent Claim
41 words
A delay action battery according to claim 1, wherein said casing and said ampoule are cylindrical in shape and said cell plates are annular plates fixed to said casing and extending into the annular chamber between said casing and said ampoule.
Claim 4
Dependent Claim
28 words
A delay action battery according to claim 1, wherein the ampoule contains a means responsive to expansion and contraction of said electrolyte to maintain substantially atmospheric pressure therein.
Claim 5
Dependent Claim
26 words
A delay action battery according to claim 3, wherein the means is a bellows immersed in and non-permeable to said electrolyte and open to the atmosphere.
