    摘要: A burner module for delivering a flow of chemical reactants to a combustion site of a chemical vapor deposition process includes a plurality of substantially planar layers. The substantially planar layers are arranged in a generally parallel and fixed relationship and define an inlet, an outlet and a passage fluidly connecting the inlet and outlet. At least one of the layers is a distribution layer having a plurality of apertures therethrough and fluidly communicating with the passage. The plurality of apertures collectively define a non-uniform pattern arranged and configured to improve the uniformity of a flow out through the outlet. Burner adapter and assembly embodiments are also included.

    摘要: The present invention is directed to a method and apparatus for forming soot used in making glass, and in particular, optical waveguides. A liquid precursor (66) is first fed into orifice (52) of a liquid orifice insert (48) within an injector (44) positioned within an atomizing burner assembly, and is thereafter discharged from the injector into a pressurization chamber (56). An atomization gas (70) is also fed into the pressurization chamber (56) to mix with the liquid precursor liquid stream (68) which breaks into droplets (76). The liquid precursor and atomization gas arm forced under pressure out of an atomization orifice (32) on the face of the burner (30) assembly. Flame gas (74), reaction gas (84) and shield gas (82) are ejected from burner orifices (40, 38, 36 and 34) to produce the flame. The atomized liquid precursor thus discharged is fed into the flame (72) produced at the face of the burner assembly where the atomized liquid precursor reacts with the flame to form soot (78) on a rotating mandrel (80).

    摘要: A burner manifold apparatus (10) for delivering reactants to a combustion site of a chemical vapor deposition process includes fluid inlets (32a, 32b), fluid outlets (49), and a plurality of fluid passages (50) extending therebetween. The fluid passages (50) converge toward each other from the fluid inlets to the fluid outlets. One embodiment includes a manifold base (12), a pressure plate (14), and a manifold burner mount (16) for mounting thereto a micromachined burner (58). The fluid passages (50) internal to the manifold base are configured to distribute symmetrically the fluid to the manifold burner mount. The fluid is then channeled through fluid passages in the manifold burner mount. The fluid passages converge, yet remain fluidly isolated from each other, and the fluid passages create a linear array for producing linear streams of fluid. Alternatively, the burner manifold apparatus may include a plurality of manifold elements in a stacked arrangement. In this alternative embodiment, the manifold elements are configured to produce a linear array of fluid passages at the top of the stack, increasing the number of fluid passages at each level of the stack closer to the top. As yet a further alternative, the burner manifold may be produced by extruding a particulate composite through a die to produce a manifold having fluid passages therein. This extruded manifold generally has a tapered section to which a burner may be mounted.

    摘要: The present invention is directed to a system and method for delivering liquid reactants through a burner assembly to form soot used in the manufacture of glass, and in particular, optical waveguides. Due to the tendency of liquid reactants to react to form solids when exposed to water in the air, an evaporative liquid is first delivered through the burner assembly to the combustion zone. Once steady state liquid flow has been achieved in the system, the evaporative liquid is transitioned to the liquid reactant. The liquid reactant is delivered along the same path to the burner assembly, which discharges the liquid reactant into the combustion zone as an atomized liquid to form soot used in the manufacture of glass. Once the desired quantity of soot has been formed, the liquid reactant is transitioned back to the evaporative liquid while maintaining steady state flow. After the liquid reactant has cleared the system, flow of the evaporative liquid is terminated and the burner assembly flame turned off. Because the evaporative liquid is the last liquid to leave the burner assembly, no reactants are present to form solids and the burner assembly remains plug free. Preferably, the liquid reactants are housed within a dry environment to provide a reaction free area for staging the liquid reactants prior to delivery, thus facilitating and expediting multiple system runs with different liquid reactants.

    摘要翻译: 本发明涉及一种用于通过燃烧器组件输送液体反应物以形成用于制造玻璃,特别是光波导的烟灰的系统和方法。 由于当暴露于空气中的水时液体反应物反应形成固体的倾向,首先通过燃烧器组件将蒸发的液体输送到燃烧区。 一旦在系统中达到稳态液体流动,则蒸发液体转变为液体反应物。 液体反应物沿着相同的路径输送到燃烧器组件,其将液体反应物作为雾化液体排放到燃烧区中,以形成用于制造玻璃的烟炱。 一旦已经形成所需量的烟灰,液体反应物在保持稳态流动的同时转移回蒸发液体。 在液体反应物已经清除系统之后,蒸发液体的流动被终止并且燃烧器组件的火焰被关闭。 因为蒸发液体是离开燃烧器组件的最后一个液体,所以不存在反应物以形成固体并且燃烧器组件保持无堵塞。 优选地,液体反应物容纳在干燥环境中以提供反应自由区域,用于在输送之前分级液体反应物,从而促进并加速与不同液体反应物的多次系统运行。

    摘要: A method and apparatus for drawing an optical waveguide fiber which minimizes fiber bow caused by differential stresses in the cladding layer of the fiber are disclosed. The fiber is drawn from a preform which is heated in a draw furnace. Gases introduced at the top of the furnace form a boundary layer adjacent to the fiber which passes through the furnace, along with the fiber, into a tube. The tube isolates the fiber from the ambient atmosphere so that the boundary layer of gases established in the furnace remains substantially uniform until the viscosity of the cladding layer of the fiber is high enough to minimize differential stresses around the circumference of the fiber.

    摘要: A yad-mezuzah casement includes a yad, at least a portion of which serves as a mezuzah casement. A mezuzah may be contained within the mezuzah casement. The mezuzah casement may be contained within the yad, attached to an outer surface of the yad or interposed between the yad and a bracket that includes an attachment fixture used for mounting the yad-mezuzah casement to a doorpost of a building or a room. The yad-mezuzah casement, which itself includes no attachment fixture, provides an opportunity for continuous display of a yad that may be received by a Jewish youth participant at a B'nai Mitzvah ceremony. Together, the yad-mezuzah casement and the mounting bracket provide a yad-mezuzah casement kit.
