~ 1 -Method and a~paratus for generatin~ a vapor stream Technical Field This invention relates to methods and apparatuses for generating vapor streams.
Background of the Invention Vapor streams are today generated and utilized in a number of industrial applications. For example, in con-structing preforms from which optical fibers may ~e drawn, vapors of materials such as SiC14, GeC14, POC13 and BBr3 ar~ ~enerated and delivered to a preform ~onstruc-tion site where they are reacted and deposited in or on a support.
Vapor streams are also generated and utilized in internal combustion engines such as those used in powering motor vehicles. In this application a vapor stream is ordinarily created either by the use of carburetion or fuel injection systems.
A long term problem and limitation commonly associated with known described methods of generating vapor streams, however, has been that of accurately and rapidly con-trolling the mass flow rate of the vapor present within the vapor stream, and a need thus exists for means for generating vapor streams with enhanced control speed and accuracy in diverse fields of technology. Accordingly, it i5 to this general problem to which the present invention is primarily directed.

In one form of the invention, a jet of electro-statically chargeable liquid particles is provided which is electrostatically controlled for selectively metering some of the liquid particles into a vaporizer where the particles are vaporized.
In another form of the invention, all of the select-ively metered particles are injected into a carrier gas stream where the particles are vaporized.

~ 2 --In another form of the invention the stream of electrostatically chargeable liquid droplets is introduced ; within a carrier gas stream, but only selected quantities of the droplets are allowed to remain within the stream long enough to become vaporized.
Brief Description oE the Drawiny The drawing is a schematic diagram of apparatus for generating a vapor stream in accordance with the invention.
Detailed Description ~ eferring to the drawing, there is schematically illustrated apparatus for generating a vapor stream which includes a conventional non-impact ink jet generator generally designated at 10. The jet generator includes an ultrasonic drop generator 12, a charge tunnel 14, and a pair of deflection plates lh and 16', such as those sold by the A. B. Dick Company of Elkgrove, Illinois, as their Part Nos. 339000-11, 339015 and 331312, respectively. For a detailed explanation of the generator and its operation reference may be made to the article by Kuhn and Myers titled "Ink-Jet Printing" in the April 1979 issue of Scientific American.
The ultrasonic drop generator, charge tunnel, and the deflection plate 1~ are each electrically coupled with control electronics while the deflection plate 16' is electrically grounded. The jet generator is positioned adjacent to a conduit 18 having an aperture 20 formed in its side Eacing and in direct line with the jet gerlerator.
A funnel 22 is located behind and slightly above the conduit and aperture. A drain tube 24 depends downwardly from the funnel and back to the ultrasonic drop generator 12 through unshown pump means. The jet generator 10 is housed within an enclosure through which conduit 18 extends.
In one application, the apparatus may be used for generating a vapor stream for use at an optical fiber preform construction site. In this application, the - . . - .
:: ; ! . `
'.~ 37S9 ultrasonic drop generator 12, rather than being filled with ink as it would be where used as a printer, is instead filled with a dielectric liquid (i.e., one which can be electrostatically charged) such as SiC14, GeC1~, POC13 or BBr3. Preferably, the dielectric liquid has a viscosity of less than 100 cps Eor efficient drop generation. For an internal combustion engine application, a liquid ~uel such as gasoline, ethyl alcohol or methyl alochol is instead supplied to the ultrasonic drop generator. A carrier gas, such as oxygen, helium or argon having a liquefaction temperature substantially lower than the boiling temperature of the dielectric liquid is then drawn through the conduit 18 for preform construction. ~ith the engine application air, comprised of oxygen and nitrogen, is instead drawn through the conduit. Since the jet generator is enclosed in a dead space about the aperture 12 the dead space itself will also be filled with the carrier gas. A
stream or jet of droplets is then generated and propelled towards the aperture 20 from the ultrasonic drop generator 12 at a selected, preferably constant rate, by a control signal transmitted over line 26 between the control electronics and the drop generator. A constant electrostatic potential is established across plates 16 and 16' by means of line 27. Digital signals are generated by the control electronics and applied to the charge tunnel 1 over line 28. During the application of a voltage to the tunnel 1~, the liquid droplets then passing there through become charged. In the intervals between the digital voltage pulses, the liquid droplets passing through the 3~ tunnel are not charged. Since only some of the droplets become charged, only some are deflected (upwardly, in this embodiment) as they pass through the electrostatic field between the deflection plates 16 and 16'. In this arrangement,only the uncharged and undeflected portions of the jet or train of droplets emitted by the ultrasonic drop generator are introduced into conduit 18 through aperture 20 where they vaporize. The charged portions of the jet .
~. :~ : : . . : : : ~
~ 2~
are deflected by the charge plates 16 and 16' over -the conduit and into the funnel 22. These droplets then gravitate downwardly and illtO conduit 2~ to be pumped back to the drop generator 12.
The ratio of vapor to carrier gas ~ay be nonitored downstream withir) conduit 1~ so that deviatiorls Erom a desired ratio may be corrected by the control electronics. For example, should a sensecl ratio of vapor to carrier gas required to deliver a desired vapor mass flow rate to an optical fiber preform construction si-te at a given carrier gas flow rate deviate from that ratio desired, a correction signal may be fed back to the control electronics. Through conventional control circuitry the control electronics then adjusts the digital signal applied to the charge tunnel whereupon a greater or lesser portion of the jet is then injected into the carrier gas stream.
In an engine application such control signals would ordinarily be generated in response to throttle and engine cycle changes. A typical flow rate for constructing a pre~orm would be one liter of carrier gas per minute into which 400 milligrams of droplets are injected per minute and 400 milligrams of droplets recirculated per minute.
~ith an engine fuel application some 1~5 grams of fuel may be injected per minute into an airstream flowing at a rate of some 2180 grams per minute.
Since the dead space about aperture 20 is filled with the carrier gas, at startup some portion of the droplets may vaporize within the dead space. However, as this space becomes more saturated most of the jet will then pass through the dead space and enter the conduit with little loss due to transit vaporization. In any event system stabilization is rapidly achieved.
The apparatus just described may assume other forms. For example, rather than have a signal applied to the charge tunnel, a constant DC charge may be placed thereon to charge all of the liquid particles passing therethrough. In this case a signal, digital or analog/ is ::

~2~3759 appli~d to the plate 16 to effect deflection of selected portions of the stream of droplets passing there-through.
Then too, the conduit aper-ture 20 may be loca~ec] either within the flight path of the charyed or the un~harged particles, or within the path of those charged particles which have or have not been deflected. That the collectec~
droplets within the funnel 22 are recirculated is, of course, also optional.
A further modification is to place the entire jet generator (10) within the conduit 18 so as to maintain one stream of droplets within the carrier gas stream for a sufficient time in which to be vaporized while directing other droplets within the jet out of the carrier gas stream as through an aperture in a conduit side before they have had sufficient time in which to become vaporized. In the embodiment illustrated, however, the droplets vaporize after passing through aperture 20 before striking the opposite wall of conduit 18. The time of transit across the inside of the conduit may be varied by alteration in the inside diameter of the conductor, the orientation of the conduit relative to the flight path of the droplets entering the conduit, or by changing the velocity of -the jet emitted by the drop generator. If desired, a group of generators may be employed so as to create mixtures of vapors with variable mixture ratio control.
In addition, it may not always be necessary that the droplets ~e propelled into a carrier gas. For example, the droplets may be metered into a vaporizer of the type having a hot plate. Upon striking the plate the droplets are vaporized and create pressure sufficient to cause a vapor stream to be emitted from the vaporizer.
