Abstract:
A fire-suppression apparatus that includes a pneumoacoustic atomizer for delivering a mist of liquid (e.g., water) in the form of droplets having a size in the range of about 50 to 90 microns. The mist is suspended in a fire-suppressing gas such as nitrogen. Gas is supplied to the pneumoacoustic atomizer from a system that, in some embodiments, includes both bottles and a gas generator. To minimize consumption of fire-suppressing materials, the fire-suppression apparatus can be operated in a pulsed mode wherein delivery of fire-suppressing materials is interrupted unless a sensor detects a fire re-flash. In some variations, the pneumoacoustic atomizer operates at very low pressures, as is desirable for use in aircraft.
Abstract:
A drug delivery device and method is disclosed which produces aerosolized particles of pharmaceutically active drug for delivery to a patient by inhalation. The device is comprised of a liquid feeding source such as a channel to which formulation is added at one end and expelled through an exit opening. The feeding channel is surrounded by a pressurized chamber into which gas is fed and out of which gas is expelled form an opening. The opening from which the gas is expelled is positioned directly in front of the flow path of liquid expelled from the feeding channel. Various parameters are adjusted so that pressurized gas surrounds liquid flowing out of the feeding channel in a manner so as to maintain a stable capillary microjet of liquid until the liquid exits the pressure chamber opening and is aerosolized. The aerosolized particles having a uniform diameter in the range of about 1 to 5 microns are inhaled into a patient's lungs and thereafter reach the patient's circulatory system.
Abstract:
This invention is an applicator for dispensing a substance comprising first and second components of any mixture of fluids for either medical or other applications, in an exemplary application, and a biological adhesive such as a fibrin sealant. The applicator consists generally of a spray head (100), a main body (200), and an air supply tube (400)
Abstract:
Method of atomization control and related gas atomizing nozzles which enable variation of the degree of atomization, the liquid and gas flow rates and the atmospheric spray dilution. Varying the thickness of the flowing liquid (L) and adjacent atomizing gas sheets (G) varies the droplet size and atmospheric spray dilution. Transverse sheet size is varied to change nozzle capacity. Annular and linear sheet forming nozzles (100), (200), and (300) are described. Nozzles are also described with flexible divider walls (320) whereby thickness of the flowing sheets may be varied by altering relative flow pressures.
Abstract:
Embodiments for producing un-agglomerated, monodisperse droplets using a liquid sheet are provided. Nozzles with exit slit openings shape a spray liquid into a thin liquid sheet as the spray liquid exits from the slit opening. Stable multi-jet operation is achieved by including notches along the edge of the slit. The notches separate the liquid sheet into multiple jets to provide anchoring and stable multi-jet operation. In some embodiments, the liquid sheet electrospray techniques and nozzles described herein provide high mass throughput and versatile multiplexing spray systems while reducing the engineering effort and high manufacturing cost
Abstract:
The present invention relates to a fluid ejector comprising a first tube (1; 101) and a second tube (3; 103), the first tube (1; 101) being located inside the second tube (3; 103), the first tube (1; 101) and the second tube (3; 103) having outlet ends (10, 11; 110, 111) adjacent each other, the first outlet end (10; 110) of the first tube having a first diameter.(D1), the second outlet end (11; 111) of the second tube (3; 103) having a second diameter (D2), the first tube (1; 101) being equipped with holes (13; 113) in the area of its outlet end (10; 110). The invention also relates to a method for mixing two fluids. It is significant of the fluid ejector according to the present invention that the holes (13; 113) define a portion (12; 112) of the first tube (1; 101), said portion (12; 112) having a length (L) in the longitudinal direction of the first tube (1; 101), and that the second diameter (D2) is larger than the first diameter (D1).
Abstract:
El objeto de esta invención es un método para producir micro-burbujas de tamaño uniforme utilizando un flujo co-axial de líquido que está sometido a una elevada velocidad angular en la dirección de la corriente, generándose un tamaño de burbuja mucho menor que el producido por ningún otro método que utilice co-flujo. El gas que forma las micro-burbujas es inyectado coaxialmente a través de un tubo capilar posicionado en la cercanía de un orificio generalmente circular o una tobera convergente con simetría de revolución, a través del cual descarga la corriente co-axial rotatoria de líquido y las burbujas de gas. La rotación del líquido genera una alta depresión en el eje de giro, formando chorros de gas extraordinariamente finos que dan lugar a burbujas de tamaño comparable muy pequeñas. Esta invención tiene muchas aplicaciones en tecnologías de alimentación, farmacia, biomedicina, diagnosis, ingeniería química, y medio ambiente.
