    摘要: A device for treating fluids, such as automotive exhaust gases is provided, as well as a method of manufacturing such a device. The device provides a honeycomb structure, a matrix of ceramic walls that defines a plurality of parallel, fluid-conducting cells oriented along an axis, arranged in a stacked or discontinuous configuration between an inlet and outlet, where adjacent layers of honeycomb structure are separated by layers of air spaces. Each matrix layer has opposing faces that defines the inlets and outlets of the cells, and a peripheral portion or peripheral region including an outer skin. The peripheral portions or peripheral regions of adjacent stacked ceramic layers are mutually contiguous to prevent fluid flowing through the stacked ceramic layers from leaking between said outer skins.

    摘要: An optical fiber having optical characteristics that systematically vary along its length is made by inserting a plurality of cylindrical tablets into a cladding glass tube and overcladding the tube with particles of cladding glass. Each tablet contains a core region, and it optionally contains a layer of cladding glass Adjacent tablets are capable of forming optical fiber sections having different optical properties. Prior to consolidating the glass particles, chlorine flows through the tube and over the tablets. When the tube begins to sinter, the chlorine flow is stopped and the sintering particles generate an inwardly directed force that causes the tube to collapse inwardly onto the tablets which concurrently become fused to each other. The resultant draw blank can be drawn into a low loss optical fiber. This method is particularly useful for making dispersion managed single-mode optical fibers.

    摘要: A method of making a segmented core optical waveguide preform for making fiber that is resistant to attenuation increases due to hydrogen and heat aging. A first core region comprising a silica glass rod containing at least a first dopant is inserted into a central opening of a second core region comprising silica soot containing a second dopant. The first core region and second core region are consolidated together to form a segmented core region and cladding is deposited on the outer surface of the segmented core region.

    摘要: An optical fiber having optical characteristics that vary along its length is made by assembling a plurality of cylindrical glass or soot tablets into or along a glass tablet alignment device, then fused into monolithic assembly. If desired, additional glass may be applied to the assembly before or after the fusing step. A vacuum is preferably applied during the fusing step. Each tablet preferably contains a core region, and it optionally contains a layer of cladding glass. Adjacent tablets are capable of forming optical fiber sections having different optical properties. Prior to consolidating the glass particles, chlorine preferably flows through or around the tablets and alignment device. The resultant draw blank can be drawn into a low loss optical fiber having short transition regions between adjacent areas of fiber. This method is particularly useful for making dispersion managed single-mode optical fibers.

    摘要: A fiber optic coupler is formed by providing a glass tube having a longitudinal aperture extending therethrough. Protective coating is removed from a region of a first optical fiber intermediate the ends thereof. Protective coating is removed from an end region of at least one other optical fiber. The coated portion of the first fiber is threaded through the tube until the uncoated region thereof is near the tube end. The size of the aperture is insufficient for simultaneously receiving the coated portions of the first and second fibers in side-by-side relationship at the coated portion of both. The uncoated region of the second fiber is placed adjacent that of the first fiber, and both uncoated regions are simultaneously fed into the tube aperture. After the threading operation has continued until the uncoated regions extend through the midregion of the tube, the midregion is heated to collapse it about the fibers, and the central portion of the midregion is drawn to reduce the diameter thereof over a predetermined length.
