Abstract
Abstract A device for arming an explosive missile. Fluid pressure for operation of the device is provided by ram air, which drives a flueric oscillator. A count of the output cycles of the oscillator determines the distance through the air that the missile has travelled. When the count reaches a predetermined point, unless other conditions inhibit arming, a detonator is armed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
In a flueric device carried by a missile and operated by environmental fluid pressure to arm the missile, the improvement comprising: means responsive to the movement of said missile through the environmental fluid for admitting pressurized environmental fluid to said device; splitter means for separating said pressurized environmental fluid into two steams; oscillator means driven by one pressurized fluid stream for generating fluidic pulses; a flueric multistage counter for counting said fluid pulses constituting the output of said oscillator means; a bistable flueric amplifier driven by said other stream and having an output passage thereof fluid cup coupled to a detonator for said missile; means normally biasing the output of said bistable flueric amplifier to another outlet passage thereof; and means fluid coupling the output of said flueric multistage counter to a control passage for supplying a control signal for said bistable flueric amplifier to overcome said bias upon reaching of a predetermined count to effect arming of said missile.
Claim 2
Dependent Claim
160 words
In a flueric device carried by a missile and operated by environmental fluid pressure to arm the missile, the improvement comprising: means responsive to the movement of said missile through the environmental fluid for admitting pressurized environmental fluid to said device; splitter means for separating said pressurized environmental fluid into two steams; oscillator means driven by one pressurized fluid stream for generating fluidic pulses; a flueric multistage counter for counting said fluid pulses constituting the output of said oscillator means; a bistable flueric amplifier driven by said other stream and having an output passage thereof fluid cup coupled to a detonator for said missile; means normally biasing the output of said bistable flueric amplifier to another outlet passage thereof; and means fluid coupling the output of said flueric multistage counter to a control passage for supplying a control signal for said bistable flueric amplifier to overcome said bias upon reaching of a predetermined count to effect arming of said missile.
Claim 3
Dependent Claim
59 words
The device according to claim 1 wherein said flueric multistage counter iNcorporates frequency stepdown means responsive to said first stream for providing an output indication of the number of cycles of said varying intensity and logic means responsive to said said output indication for providing said control signal for overcoming the biasing signal applied to said bistable flueric amplifier.
Claim 4
Dependent Claim
78 words
The device according to claim 2, wherein said stepdown means further comprises: a frequency divider means responsive to said first stream for providing a divider output signal which varies at a frequency less than and proportional to said predetermined frequency; and said counter means are responsive to said divider output signal for counting the number of cycles in said divider output signal when providing said control signal for overcoming the biasing signal applied to said bistable flueric amplifier.
Claim 5
Dependent Claim
55 words
The device according to claim 1, further comprising: a fluid switch driven by the output of said bistable flueric amplifier to provide an arming signal to said detonator; and control means for said switch responsive to an inhibit signal for preventing the arming signal from said bistable flueric amplifier from reaching a point of utilization.
Claim 6
Dependent Claim
27 words
The device according to claim 4, further comprising; power control means responsive to a sensor signal for controlling the amount of power reaching said bistable flueric amplifier.
Claim 7
Dependent Claim
77 words
The device according to claim 5 wherein said power control means comprises a second bistable flueric amplifier positioned intermediate of said divider and said first bistable flueric amplifier, with the output of said second bistable flueric amplifier normally operating as the power stream for said first bistable flueric amplifier, and control means for second bistable flueric amplifier receptive to said sensor signal for causing said second flow stream to be diverted from said first bistable flueric amplifier.
