Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
A flueric device comprising a deflection chamber having at least two outlet receivers, a supply nozzle adapted to introduce supersonic fluid flow into said deflection chamber, a pair of control chambers registering with said deflection chamber on either side thereof, spark discharge means disposed in each said control chambers and responsive to an input signal for inducing compression pressure on said flow to deflect said flow in between said two outlet receivers, and means for inducing a normal shock wave in at least one of said output receivers near the entrance thereof.
Claim 2
Dependent Claim
92 words
A flueric device comprising a deflection chamber having at least two outlet receivers, a supply nozzle adapted to introduce supersonic fluid flow into said deflection chamber, a pair of control chambers registering with said deflection chamber on either side thereof, spark discharge means disposed in each said control chambers and responsive to an input signal for inducing compression pressure on said flow to deflect said flow in between said two outlet receivers, and means for inducing a normal shock wave in at least one of said output receivers near the entrance thereof.
Claim 3
Dependent Claim
31 words
The device of claim 1 wherein said spark discharge means are adapted to be selectively actuated to push said fluid flow between said outlet receivers by means of said compression pressure.
Claim 4
Dependent Claim
34 words
The device of claim 1 wherein said spark discharge means are adapted to be selectively actuated to pull said fluid flow between said outlet receivers by means of a reflection from said compression pressure.
Claim 5
Dependent Claim
41 words
The device of claim 1 wherein said spark discharge means are adapted to be selectively actuated to push and pull said fluid flow between said outlet receivers by means of said compression pressure and a reflection from said compression pressure, respectively.
