| 81 | Sonic liquid atomizer | US274411 | 1981-06-17 | US4408719A | 1983-10-11 | Anthony J. Last |
| A sonic liquid atomizing device having a body member with a concave face and a resonator spaced from the face. An air nozzle projects through an opening in the face to form an annular aperture about the nozzle and an inlet for liquid connects with the annular aperture. The nozzle carries an axial stem on which the resonator is mounted and the nozzle is adjustable axially to vary the area of the annular aperture. The nozzle is tapered and its conical projection terminates on the axis of the stem between the resonator and a point one third of the distance between the resonator and the nozzle. | ||||||

| A device is disclosed which is capable of generating turbulence in a fluid as well as a sonic or ultrasonic field of predetermined frequency comprising a swirl chamber which is in fluid communication with a compression chamber and followed downstream by modulator cavities. Each successive stage of the device can alter the frequency and amplitude of the waves produced and in certain embodiments can act to intensify the vortices created in the fluid passing through the device to produce both mold controlled turbulence as well as stable high frequency/high amplitude acoustic (sonic or ultrasonic) vibration at the exit port. | ||||||
| 83 | Ultrasonic device for scaring animals from a moving vehicle | US849190 | 1977-11-07 | US4150637A | 1979-04-24 | Monroe Penick |
| An air scoop is positioned to receive and compress air in response to movement of a vehicle or its radiator-cooling fan. The compressed air is conducted to a whistle for producing sound at a frequency somewhat above human hearing range. The whistle is preferably provided with a dished reflector for forwardly beaming the sound. The reflector can optionally also be the air scoop. | ||||||

| In a first embodiment, a source of fluid under pressure is supplied to a conduit that is terminated by a transverse resonant cavity preferably having a square cross section. The cross section of the conduit and the cavity are dimensionally related. In a second embodiment, a shock wave generator is coupled to a transverse resonant cavity. The component wavelengths of the shock waves and the cross-section of the cavity are dimensionally related. A third embodiment combines the first and second embodiments. The primary resonant cavity itself may be supplemented by auxiliary resonant cavities that communicate with a partially enclosed area into which the primary resonant cavity opens. One or more of the auxiliary cavities may be fed in parallel with the primary cavity by auxiliary conduits. Further, an auxiliary cavity may be arranged in series with the primary cavity to form a fluidic reflecting surface at the back of the primary cavity. Fluid may be supplied to a transverse resonant cavity by two or more feed conduits. The cavity may form a network of closed interconnected geometric channels such as circles, squares, and triangles, that are either arranged in a single plane or in stacked planes.

| A device for generating ultrasonic waves in a fluid preferably used in emulsifying water and fuel oil and the like constructed of two side plates (each having at least one recess, occurring in adjacent pairs) and a thin steel membrane disk having a liquid access groove (discontinuities) cut out of said disk and extending into said recess such that the remaining portion of the membrane disk extending across each recess pair vibrates (preferably resonates) in the liquid flowing through said groove and into one of said recesses to pass out a discharge conduit extending from the base of such recess.

| Engine vacuum is used to draw a stream of air into the intake system. Some of the energy of this air stream is converted to pressure waves. The flow rate of the air stream is controlled responsive to the mode of engine operation to provide the proper amount of pressure wave energy.

| 88 | Acoustic sensing device | US3729702D | 1970-12-21 | US3729702A | 1973-04-24 | BEEKEN B; O KEEFE R |
| A sensing device having a high frequency sonic wave source that generates an acoustic beam is supplied by a fluid source at above ambient pressure serially connected through a normally open fluidic switch connected in the circuit as an OR gate. The sonic wave generator is disposed to direct an acoustic beam toward a target where it is reflected towards the control input of an acoustically sensitive fluidic receiver whose output is connected to the control input of the fluidic switch. The latter is modulated by the output of the receiver which is responsive to the acoustic beam in such a way that the fluidic switch is changed to a flow inhibiting condition by the receiver when the reflected acoustic beam is present and to a flow passing condition by the receiver when the reflected acoustic beam is absent. The sonic wave generator is thereby maintained in an oscillatory mode in an on-off sequence such as an equal wave multivibrator. The period of the multivibrator in the sensing device is dependent on two factors: (1) the time constant of the fluidic circuit and (2) the time of propagation of the sound from the generator to the acoustically sensitive fluidic receiver. The former is a constant which can be determined for each circuit and the latter is dependent on variable conditions external to the fluidic circuit. This permits measurement of dependent variable conditions of the system, through which the acoustic beam passes, viz. distance that the acoustic beam travels as well as temperature, density and composition of the fluid medium through which the acoustic beam travels.
