Abstract: 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.

Abstract: A system for cleaning and verifying the cleanliness of the interior surfaces of hollow items, such as small bottles, tanks, pipes and tubes, employs a rotating spray head for supplying a gas-liquid cleaning mixture to the item's surface at a supersonic velocity. The spray head incorporates a plurality of nozzles having diverging cross sections so that the incoming gas-liquid mixture is first converged within the spray head and then diverged through the nozzles, thereby accelerating the mixture to a supersonic velocity. In the preferred embodiment, three nozzles are employed; one forwardly facing nozzle at the end of the spray head and two oppositely facing angled nozzles exiting on opposite sides of the spray head which balance each other, and therefore impart no net side load on the spray head. A drive mechanism is provided to rotate the spray head and at the same time move the head back and forth within the item to be cleaned.

Abstract: 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.

A bore through the first nozzle member provides for fluid communication in the first passage portion from the bore to between the valve member portion and the valve seat when the valve member portion is displaced away from the seat.

Abstract: Apparatus for initiating pyrolysis of a feedstock by establishing a continuous, standing shock wave. Several embodiments of a shock wave reactor (10, 100, 150) are disclosed; each is connected to receive an ethane feedstock and a carrier fluid comprising superheated steam. The feedstock and the carrier fluid are pressurized so that they expand into parallel supersonic streams that mix due to turbulence within a mixing section (36) of a longitudinally extending channel (12) of the shock wave reactor. The carrier fluid heats the ethane feedstock as it mixes with it, producing a mixture that flows at supersonic velocity longitudinally down the channel. A gate valve (44) disposed downstream of the channel provides a controlled back pressure that affects the position of the shock wave and the residence time for the reaction. The shock wave rapidly heats the mixture above a pyrolysis temperature, producing a desired product by cracking the feedstock.

Abstract: Gas dispersion in a liquid is enhanced by combining the gas and liquid in close proximity to a venturi or other flow constriction means used to create supersonic flow velocities and subsequent deacceleration to sub-sonic velocity. When a venturi is employed, the gas-liquid mixing occurs in the converging portion of the venturi or upstream but in close proximity to said venturi. Turbulent flow conditions upstream of the venturi or other flow constriction means adequate to disperse the gas uniformly in the liquid are not required and, surprisingly, the gas and liquid need not be uniformly dispersed prior to acceleration to supersonic velocity.

To make this possible, a fuel air emulsion formed with primary air is introduced from a mixing duct via a constricted orifice of a tubular nozzle at a bore constriction, at which there is always a sonic velocity when there is a critical and supercritical pressure ratio, into the secondary air flow where it is superfinely atomized in the secondary air flow, with a maximum velocity differential, aided by subsequent pressure surges.

Abstract: In order to dissolve a gas such as oxygen in a liquid, typically aqueous, a stream of liquid is taken from tank 2 by a pump 10 and pressurized thereby. Oxygen is introduced into the stream via a conduit 18 upstream of a venturi 20. The resulting mixture of oxygen bubbles and liquid is accelerated from a sub-sonic to a super-sonic velocity as it flows through the venturi 20. The resultant shockwave is effective to reduce the size of the bubbles. The stream of liquid carrying oxygen bubbles dispersed therein is then transported at sub-sonic velocity along the conduit 12 to a sparge pipe 14 through which it is introduced into the main volume 4 of liquid into the tank 2. As the liquid passes through the orifices of the sparge pipe 14 so it is again accelerated to a super-sonic velocity and another shockwave is created thereby causing the bubbles to reduce in size such that they readily dissolve in or are consumed by the main volume of liquid.

This eliminates the possibility of fuel particles becoming agglomerated and produces desirable air-fuel mixtures.

Abstract: A combustible mixture of air and minute fuel droplets is produced for supply to the cylinders of an internal combustion engine. This mixture is formed by accurately controlling both the atomization of fuel and the mass flow rate of air over substantially the entire operating range of the engine.

The sonic velocity air at the constricted zone divides the fuel into minute droplets that are uniformly entrained throughout the air stream. The area of the constricted zone and the quantity of fuel introduced are adjustably varied in correlation with operating demands imposed upon the engine.
