Flame produced vapors for combustion chemical vapor deposition are redirected from the direction of the flame by differential atmospheric pressure, such as positive pressure provided by a blower or negative pressure provided by a vacuum. This allows, for example, lower surface temperatures of substrates being coated with flame-produced vapors and coating of interior surfaces.

Tubular needles have a reduced inner diameter tip portion that increases back pressure behind the tip portion. This constricted tip portion promotes improved atomization, particularly when the liquid passes through the needle at near-supercritical conditions. A preferred method for constricting the inner diameter of a needle tip is to dip the dip of the needle in an electroless plating solution, such as an electroless nickel solution.

Narrow diameter needle having reduced inner diameter tip

Tunable capacitors () have a dielectric material () between electrodes, which dielectric material comprises an insulating material () and electrically conductive material, () e.g., conductive nanoparticulates, dispersed therein. In certain cases, enhanced tune-ability is achieved when the dielectric material comprises elongated nanoparticulates (). Further enhanced tune-ability may be achieved by aligning elongated particulates in an electrode-to-electrode direction. Nanoparticulates may be produced by heating passivated nanoparticulates. Passivated nanoparticulates may be covalently bound within a polymeric matrix. High bias potential device structures can be formed with preferential mobilities.

A continuous feed coater for coating a length of substrate with vaporized or sprayed material, is disclosed. A specific example is a roll-to-roll coater which includes two lower supply rollers for supporting two webs of uncoated material, and two upper take-up rollers for supporting the webs after they are coated. A central web-support forms a plenum that acts as a deposition chimney or chamber by bringing the two webs into close proximity to each other to form two large walls of the plenum. The ends of the webs are sealed using side dams to form the chimney with a rectangular cross section such that the vapor cannot exit from the edges of the material. The vaporized coating constituents to be deposited on the rolled material are directed into the deposition plenum from a coating material supply source located at the bottom of the plenum, and are exhausted through the top of the plenum. By providing a plenum having two large surface area walls formed of the material to be coated, an extremely efficient coating system is provided. The top of the plenum includes an exhaust system with an orifice plate with a plurality of orifices spaced across the width of the deposition plenum. These orifices restrict gas exhaust to provide the gas and vapor residence time for the materials being used.

Continuous feed coater

The present invention involves controlled atomization of liquids for various applications such as part/droplet seeding for laser-based measurements of flow velocity, temperature, and concentration; flame and a plasma based elemental analysis; nano-powder production; spray drying for generation of small-sized particles; nebulizers in the production of sub-micron size droplets and for atomizing fuel for use in combustion chambers. In these and other atomizer applications the control of droplet and/or particle size is very critical In some applications extremely small droplets are preferred (less than a micron), while in others, droplet diameters on the scale of several microns are required. The present invention has the flexibility of forming droplets within a particular range of diameters, wherein not only the size of the average droplet can be adjusted, but the range of sizes may be adjusted as well. The atomizer ( ) itself is in the form of a heated tube ( ) having an inlet end ( ) and an outlet end ( ). As liquid travels through the tube it is heated and upon exiting the tube and entering a reduced pressure area the liquid atomizes to form very fine droplets. By electrically heating the tube by passing a current therethrough, the heating adjustment can be performed on-the-fly allowing size adjustment during operation of the atomizer. Several different embodiments of the atomization device are disclosed.
