    摘要： Method and apparatus for supplying a gaseous raw material to plural users. A liquid raw material is evaporated by a single evaporation means and supplied to a gaseous raw material takeout portion provided with a plurality of takeout ports. The gas pressure is varied according to amounts of the gaseous raw material taken out of the takeout ports. The pressure variations are regulated by a main pressure-adjusting means mounted downstream of the gaseous raw material takeout portion. Extra gaseous raw material is sent to a gaseous raw material -condensing means, where the material is liquified. Then, the liquified material is fed back to the evaporation means. Thus, a closed circulatory loop circuit is formed. The gas pressure in the gaseous raw material takeout portion is regulated. The gaseous raw material is distributed to plural users at any desired time at their respective flow rates such that supply of the raw material to each individual user is carried out independent of supply to other users.

    摘要： The previous methods of controlling the flow of vapor transported by a carrier gas from a bubbler (10) to a using system have customarily been the thermal-conductivity mass flow meter and the temperature controlled vaporizer bubbler (10). However, such control methods have the disadvantage that fluctuations occur in the vapor mass flow.
    In accordance with the present invention the flow of vapor transported by a carrier gas from a bubbler (10) to a using system is controlled to provide on uninterrupted uniform mass flow ofthevaporto the using system. Control of the flow of vapor is achieved by controlling the temperature (48) and pressure (50) within the bubbler (10).

    摘要： A system for delivering a liquid reactant (2) at high flow rates to an oxidation/flame hydrolysis glass soot deposition site (10). A first liquid only reactant (2) is delivered (7,4) to a vaporization chamber (1) to form a thin film and mixed with oxygen (20) after vaporization. Additional vaporized reactants (30) are thereafter mixed (11) with the vaporized first liquid (1) prior to delivery to an oxidation/flame hydrolysis burner (10) to form a glass soot outer cladding layer on a soot preform. The soot preform is subsequently fused to form a high quality glass blank for drawing into optical fiber.
