Abstract
Abstract A fluidic generator (38) employing a fluidic feedback oscillator (12) in combination with a magnetogenerator (41) is described. Oscillational changes in pressure produced within the feedback oscillator are transmitted to opposite sides of a pole cap (74) which reciprocates a coil (70) in a magnetic field.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A fluidic generator, comprising in combination: fluidic circuit means for forming a feedback oscillator having first and second output channels; the oscillator being operable to produce oscillational changes in pressure within the first and second channels; a permanent magnet connected to the fluidic circuit means and providing a magnetic field; a wire coil connected in suspended relation to the permanent magnet so as to permit reciprocation of the coil within the field; and means connected to the coil for reciprocating the coil in response to the oscillational changes in order to induce voltage in the coil.
Claim 2
Dependent Claim
96 words
A fluidic generator, comprising in combination: fluidic circuit means for forming a feedback oscillator having first and second output channels; the oscillator being operable to produce oscillational changes in pressure within the first and second channels; a permanent magnet connected to the fluidic circuit means and providing a magnetic field; a wire coil connected in suspended relation to the permanent magnet so as to permit reciprocation of the coil within the field; and means connected to the coil for reciprocating the coil in response to the oscillational changes in order to induce voltage in the coil.
Claim 3
Dependent Claim
19 words
A generator as recited in claim 1 wherein the reciprocating means comprises a flexural member connected to the coil.
Claim 4
Dependent Claim
54 words
A generator as recited in claim 1 further comprising: an outer pole piece connected to the magnet and circumscribing the coil; and an inner pole piece connected to the magnet and circumscribed by the coil; the inner pole piece having a bore formed therein; the bore being a continuation of the first output channel.
Claim 5
Dependent Claim
16 words
A generator as recited in claim 3 further comprising a piston slidably disposed within the bore.
Claim 6
Dependent Claim
79 words
A generator as recited in claim 3 wherein the fluidic circuit means comprises a header forming a channel which is a continuation of the second output channel; the continuation of the second output channel being spaced from and aligned in opposed relation to the continuation of the first output channel; the reciprocating means being disposed between the continuations and operative to reciprocate the coil in response to transmission of the oscillational changes from the continuations to the reciprocating means.
Claim 7
Dependent Claim
50 words
A generator as recited in claim 5 further comprising first and second aligned pistons, each being slidably disposed in a respective one of the continuations; the reciprocating means being operative to reciprocate the coil in response to transmission of the oscillational changes from the pistons directly to the reciprocating means.
Claim 8
Dependent Claim
19 words
A generator as recited in claim 6 wherein the reciprocating means comprises a flexural member connected to the coil.
Claim 9
Dependent Claim
19 words
A generator as recited in claim 5 wherein the reciprocating means comprises a flexural member connected to the coil.
Claim 10
Dependent Claim
23 words
A generator as recited in claim 7 further comprising a second flexural member connected to the coil and spaced from the reciprocating means.
Claim 11
Dependent Claim
23 words
A generator as recited in claim 8 further comprising a second flexural member connected to the coil and spaced from the reciprocating means.
