Abstract: An ultrasonic humidifier comprising an atomizing chamber 2 containing water which is atomized by an ultrasonic vibration board 4 to be discharged therefrom. A water supply tank 11 is provided with a valve rod 14 having a valve 15 adapted to close a water outlet 13 thereof. The valve rod 14 protrudes by the elastic force of a spring. A water supply tank chamber 5 which, when said water supply tank is mounted therein with the valve rod 14 directed downward, relatively depresses the lower end of the valve rod with the bottom thereof to open the water outlet 13. A valve rod receiving chamber 6 communicates with the tank chamber. The water level of the atomizing chamber 2 is equal to the level of said water outlet 13 of the water supply tank which confronts with the valve rod receiving chamber 6. A water delivering path (17a or 17b) establishing communication between the valve rod receiving chamber 6 and the atomizing chamber is bent and elongated in a horizontal plane thereof.

Abstract: A method for treating a body of liquid with a gas, which method comprises passing a stream of the liquid through a conduit, injecting gas intermittently into the stream at high pressure so as to dissolve at least some of the gas in the liquid stream, and introducing the stream containing dissolved gas and undissolved bubbles of gas into the main body of liquid under turbulent conditions such that the undissolved bubbles are shattered into even finer bubbles which dissolve in, or are consumed within, the main body of liquid.

Abstract: This invention relates to filtering separators in particular pocket or tube filters, of the kind having a lower inlet for dirty, i.e. dust-or smoke-laden gas containing extremely adherent dust particles which is directed upwards towards the filter elements, the dust which settles when the filter surfaces are cleaned periodically being carried back to the filter surfaces by this dirty gas for agglomeration purposes and a proportion of the agglomerated dust which corresponds to the quantity of dust in the incoming dirty gas and which the said gas is not capable of carrying with it to the filter surface being extracted during the periodic cleaning of the filter elements.

Abstract: A device for carburetion of liquid fuels including an ultrasonic oscillator and at least one fuel supply nozzle which supplies fuel into engagement with the oscillator. The oscillator is disposed in an air tube so that the fuel which is acted upon by the oscillator can be mixed with air to form a fuel-air mixture.

Abstract: An improved ultrasonic nebulizer for administering a medicament aerosol to a patient. Output from an oscillator is connected through a series inductor to a transducer adjacent a reservoir which generates aerosol from the medicament. The inductor is tuned for series resonance with the bulk capacitance of the transducer. An impedance change in the transducer when liquid is removed or consumed from the reservoir reduces the power delivered to the transducer and prevents transducer damage.

The ultrasonic wave generating device in turn includes an ultrasonic transformer, for transforming electrical oscillations into mechanical vibrations, connected to an ultrasonic oscillator, a mechanical vibration amplifier, for amplifying the amplitude of the mechanical vibrations, secured to the ultrasonic transformer, and a vibratory member, having a hollow cylindrically shaped body the peripheral wall of which is secured to the tip of the mechanical vibration amplifier with the axis of the vibratory member being disposed substantially perpendicular to the longitudinal axis of the mechanical vibration amplifier. The vibratory member has its opposite ends open and is disposed within an intake passage of an engine, the same therefore not hindering the flow of fluid through the intake passage.

Abstract: Material treating apparatus including one or more pneumo-hydraulic vibrators. The apparatus includes a container with cells separated by at least one valve lying on a supporting frame, the valve having a movable valve element which is urged toward its valve-closed position by the hydrostatic pressure and optionally also by springs. On one side of the valve there is an air cell connected with a source of air under pressure, and on the other side of the valve there is a second cell containing a liquid or a liquid suspension of material to be treated. When the air cell is subjected to air under pressure, the movable valve element vibrates and generates intensive vibro-pulsation turbulent streams in the liquid material in the second cell.

Abstract: An atomizer assembly includes an ultrasonic resonator which is clamped along a clamping line near one end and driven along a driving line spaced from the clamping line. The atomizer is positioned centrally in a throat for receiving a gas flow at an inlet end and for emitting the gas flow at an outlet end. A gas diffuser is provided for directing the gas flow from the inlet end to contact the surface of the ultrasonic resonator at a high angle of incidence. A liquid flow path is provided through the clamp for directing a liquid to impinge on the vibratory surface of the ultrasonic resonator. The internal surface tension in the liquid is overcome by the vibratory motion and the liquid is cast from the surface of the resonator in atomized form at a low velocity. The atomized liquid is mixed thoroughly with the gas due to the opposing directions of the atomized liquid and the gas flow. The mixed or entrained atomized liquid is passed through the outlet end of the throat.
