    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： 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.

    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).
