Abstract

Abstract Disclosed is a chemiluminescent ordnance timer. The device comprises essentially of a first ampule which contains a first reactive component, a second ampule containing a second reactive component, a mixing chamber for receiving both reactive components and for transmitting chemiluninescent light which is created by the mixture, a plurality of capillary tubes for imparting a predetermined time delay to the reactive components on their way to the mixing chamber, and finally, means for detecting the chemiluminescent light and for actuating an appropriate mechanism. Each of the ampules containing the reactive components are designed to break upon the application of a predetermined force such as a setback or a spin force which may be encountered in a projectile. Several safety features in the form of fluid sump means are provided along the capillary path to ensure that the detonator will activate only upon a predetermined sequence of events.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 77 words
A chemiluminescent device comprising; a. a first impule containing a first reactive component; b. a second ampule containing a second reactive component; c. a mixing chamber for receiving the mixture of said first and second reactive components and for transmitting chemiluminescent light created by said mixture; d. means for directing said first and second reactive components from said first and second ampules to said mixing chamber; and e. means responsive to said light for activating a mechanism.
Claim 2
Dependent Claim 77 words
A chemiluminescent device comprising; a. a first impule containing a first reactive component; b. a second ampule containing a second reactive component; c. a mixing chamber for receiving the mixture of said first and second reactive components and for transmitting chemiluminescent light created by said mixture; d. means for directing said first and second reactive components from said first and second ampules to said mixing chamber; and e. means responsive to said light for activating a mechanism.
Claim 3
Dependent Claim 27 words
The device of claim 1 wherein said means for directing reactive components comprises capillary tubes for imparting a predetermined time delay to the flow of fluid therein.
Claim 4
Dependent Claim 40 words
The device of claim 2 further comprising means for causing said first ampule to break upon the application of a first predetermined force and means for causing said second ampule to break upon the application of a second predetermined force.
Claim 5
Dependent Claim 14 words
The device of claim 3 wherein said first and second forces are setback forces.
Claim 6
Dependent Claim 21 words
The device of claim 3 wherein said first force is a setback force and said second force is a spin force.
Claim 7
Dependent Claim 25 words
The device of claim 3 wherein said means for activating a mechanism comprises means for actuating a detonator and means for actuating an explosive train.
Claim 8
Dependent Claim 37 words
The device of claim 3 further comprising sump means associated with at least one of said capillary tubes to prevent said reactive components from reaching the mixing chamber unless the proper sequence of forces have been applied.
