Aerosol processing and inhalation method and system for high dose rate aerosol drug delivery
ActiveUS20070144514A1Increase dose rateRisk minimizationRespiratorsLiquid surface applicatorsSolvent vaporCounter flow
A method and system is disclosed which is capable of delivering at a high dose rate, respirable solid aerosols derived from aqueous- or nonaqueous-based solutions containing the desired therapeutic agent(s). The method and system comprises the integration of an aerosol generator, an aerosol evaporator, an aerosol concentrator, and an aerosol flow regulator. The aerosol generator generates 10-30 μm droplets, with a narrow size distribution. The aerosol jet is arrested by a coaxial counter-flow heated air jet, and evaporated rapidly by annular swirling heated air. Most of the air, together with the unwanted solvent vapor, is removed from the aerosol stream during the process of aerosol concentration. The output aerosol carries the dry particles to be inhaled by the patient. The respiratory-governed control of aerosol fluid generation system delivers fluid containing the test agent of interest (drug or toxin) to the aerosol generator throughout inhalation.

Solvent vapor infiltration of organic materials into nanostructures
Spaces in a nanostructure can be filled with an organic material while in the solid state below Tm (without heating) by exposing the organic material to solvent vapor while on or mixed with the nanostructured material. The exposure to solvent vapor results in intimate contact between the organic material and the nanostructured material without having to expose them to possibly detrimental heat to melt in the organic material. Solution processing methods need only to be employed to create bulk films while organic material infiltration can take place in the solid state after depositing the film.

Method and system for desorption atmospheric pressure chemical ionization
ActiveUS7544933B2Minimizing chanceHigh sensitivityMaterial analysis by optical meansIon sources/gunsSolvent vaporDesorption
A desorption atmospheric pressure chemical ionization (DAPCI) system delivers a primary ion beam composed of an inert, high velocity gas and solvent ions to a surface to effect desorption and ionization of both volatile and non-volatile species present on surfaces. A electrode having a tapered tip is connected to a high voltage power supply. The tapered tip projects outward from a capillary carrying a high-speed flow of gas. A vapor of a solvent is mixed into the annular gas flow surrounding the needle. The gaseous solvent vapor is ionized in close proximity to the tapered tip by virtue of the high voltage applied to the electrode. The high-speed flow of gas and solvent vapor ions extending outward from the capillary is directed toward a substrate on which an analyte of interest may have been deposited. The solvent vapor ions can blanket the surface of the analyte causing a static charge build up that facilitates ion desorption and additionally can provide positive ion adducts of the analyte freed from the substrate surface that can be directed toward an atmospheric intake of a mass spectrometer or other instrument capable of studying the analyte.

Solvent extraction of hydrocarbons from inorganic materials and solvent recovery from extracted hydrocarbons
InactiveUS6207044B1No pollution to the environmentIncrease surface areaLiquid organic insulatorsWorking-up pitch/asphalt/bitumen by chemical meansHydrocarbon solventsSolvent vapor
A process for the solvent separation of hydrocarbons from tar sand or contaminated soils comprises extracting the hydrocarbons from the sand or soil in a solvent extraction means to form a hydrocarbon rich solvent solution. The rich solvent is separated from the hydrocarbon in a process that utilizes flashing of the solvent in a heated flashing column at ambient pressure. The hydrocarbon is withdrawn from the bottom of the column and the flashed solvent vapors are strategicly withdrawn and passed into a condensation column from which the condensed solvent may be recycled. The flashing column is divided by a series of horizontal, vertically aligned apertured trays. The solution is introduced into the top of the column and the flashing operation is facilitated by the increase in the surface area of the solution as it flows by gravity from tray to tray. The column is maintained at a temperature, preferably above the boiling temperature of the solvent. The process is particularly adapted to the use of chlorinated hydrocarbon solvents and most particularly to the use of methylene chloride.

Manufacturing Process, Such as Three-Dimensional Printing, Including Solvent Vapor Filming and the Like
InactiveUS20080032083A1Improving dimensional resolutionControl spreadStampsWrappersPorosityCalcium biphosphate
Methods of manufacturing an article use three-dimensional printing for a portion of the manufacturing. Three-dimensionally printing is conducted onto a powder bed which contains both organic-solvent-soluble, water-insoluble particles and water soluble, organic-solvent-insoluble particles. The water-soluble particles which may be selected for properties such as size and may include more than one substance. The organic-solvent-insoluble particles may further include at least one substantially insoluble substance such as a member of the calcium phosphate family. Printing may be done using an aqueous binder liquid. After removal of unbound powder, the preform may be exposed to the vapor of an organic solvent which causes the particles of organic-soluble-polymer to fuse to each other. This may further be followed by dissolving out the water-soluble particles, if such particles were present in the powder. Solvent vapor fusing together with the use of porogen particles may also be used in manufacturing methods other than 3DP. Rather than using organic solvent, heat responsive particles can be used, and can be filmed by elevated temperatures. Articles that may be produced by the described methods exhibit features such as a high porosity and an ability to undergo large deformations without breaking, and by at least partial springback from such deformation. The springback may be substantially instantaneous or may be time-dependent involving a time period of at least several seconds.

Method and apparatus for desolvating flowing liquid
ActiveUS20100000943A1Quick releaseAvoid contactLiquid degasificationComponent separationTemporal resolutionSolvent vapor
Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets. When the droplets are sufficiently small, Stokes drag from the exiting solvent vapor carries the droplets out through the center of the cylindrical cavity. After exiting, the superheated solvent vapor further dries the droplets. Solvent vapor is removed by condensation onto a cooled surface. A freezing point reducing agent may be added to improve removal of solvent condensate. Stokes drag from a non-condensable gas maintains the dried droplets in suspension. This suspension travels through an orifice that focuses the impaction of the dried droplets onto the optical surface for infrared analysis. The deposition surface is in an evacuated chamber and is temperature controlled to freeze liquid solutes yet allowing sublimation of residual solvent.
