摘要： An apparatus and process for oxygenating a liquid. The apparatus includes a liquid pump fluidly connected to an injector having a liquid inlet forming a nozzle, a liquid outlet and an oxygen inlet therebetween, the injector arranged such that the injector liquid inlet is above the injector liquid outlet, and a downwardly opening first diffuser portion connected to the injector outlet. The first diffuser portion is serially connected to a second diffuser portion located below the first diffuser portion. Liquid being pumped by the pump is conducted downwardly through the injector and the first diffuser portion to the second diffuser portion. The process includes the steps of first, introducing a liquid under pressure into the injector and flowing it liquid downwardly through the injector at a selected liquid volume flow rate; second, introducing oxygen into the injector to create an admixture of liquid and large oxygen bubbles; third, introducing the mixture of liquid and large oxygen bubbles from the injector into the first diffuser portion at such velocity to create a shockwave in the first diffuser portion; fourth, breaking up the large oxygen bubbles into a greater number of small oxygen bubbles; fifth, introducing a mixture of liquid and small oxygen bubbles from the first diffuser portion into the second diffuser portion, which may be a continuation of the first diffuser portion and wherein the pressure of the admixture is increased; sixth, floating some of the bubbles upwards against the downward liquid flow and breaking them down to smaller size; continuing the fourth through sixth steps until the smaller bubbles no longer float upwards; and recovering the oxygen-enriched liquid.

摘要： The device is designed for nebulizing liquids and for transporting the formed aerosols. It includes components to form a fountain of liquid that is being nebulized, a container holder (4), a container (2) with contact medium (3), an additional container (5) with liquid being nebulized (6), a nebulization chamber (7), a system for transporting the aerosol to the user, an outlet duct (11), and a mechanism for regulation of rate of delivery of aerosol. The nebulization chamber (7) is designed as a double-element structure, composed of an intake tube (8) and an expansion chamber (9). In the bottom of the expansion chamber (9) outlets (10) have been made for the drainage of the non-nebulized liquid back to the section of the container remote from the base of the fountain. This reduces the negative action of the non-nebulized liquid on the effectiveness of nebulization. The expansion chamber (9) which is incorporated into the nebulization chamber (7) ensures a significant reduction in coagulation of the aerosol particles, thus increasing the efficiency of the nebulizer and particle uniformity. The latter effect is likewise heightened by this specifically designed outlet duct (10) which accomplishes a process of gravitational filtration. As a consequence of the movement of the stream in the narrow intake tube (8) there is formation of a differential pressure, enabling transport of the aerosol from the nebulization chamber to the user. The above principles are proposed for application to multi-use and single-used devices.

摘要： A direct contact steam injection heater with a coaxial steam nozzle has a converging/diverging combining tube. The converging/diverging combining tube eliminates the need for an adjustable combining tube sleeve to accommodate various flow rates of a liquid or slurry entering into the heater. The heater is especially well suited for sanitary applications because, without the combining tube sleeve, the heater can be made so that surfaces in contact with the liquid or slurry do not have pockets or folds in which liquid or particulates can accumulate. Contact surfaces in the heater are substantially self-cleaning because of turbulent mixing action, and the heater can be quickly disassembled and reassembled for manual cleaning.

摘要： An improved carburetor is provided wherein a bidirectional passage is provided between an air velocity reader and a location downstream of a throttle. Metered fuel flows into the bidirectional passage adjacent the air velocity reader. Flow direction in the bidirectional passage is dependent on the pressure relationship between the ends of the bidirectional passage.

摘要： An ejector for pumping a low pressure, supersonic driven stream to a high pressure is disclosed. Effective pressure recovery in a relatively short axial length is sought.The low pressure driven stream is flowed at supersonic velocities into the ejector. A high energy driving stream is flowed laterally of the driven stream at a supersonic velocity greater than the supersonic velocity of the driven stream and a static pressure above the static pressure of the driven stream to cause compression of the driven stream at supersonic velocities.

摘要： An apparatus for supplying aerosol fuel particles uniformly mixed with air to utilizer, as an internal combustion engine or burner. The apparatus has several fuel mixing and atomizing nozzles operable to mix one or more liquid hydrocarbon fuels and discharge the fuels through orifices in small fuel particles of uniform size. The fuel particles are mixed with air and flow through a pair of venturi throats with converging inlet walls and diverging outlet walls. The velocity of the air and fuel particles flowing through the venturi throats is at or above the speed of sound. The fuel particles are finely divided into particles between 0.5 and 1.5 micron in diameter as they move through the turbulent inlet and outlet interfaces of the air flowing through the nozzle throats at sonic and supersonic velocities and are evenly distributed into the air. The length or major dimension of one of the venturi throats is regulated with a baffle in accordance with the speed requirements of the engine.
