  • System for delivering materials to deposition site on optical waveguide blank
    Patent number: 4173305
    Abstract: A system for delivering a siliceous matrix material and selected dopants to an oxidizing reaction flame or the like. Each constituent is maintained in liquified form and transferred by means of an individually controlled metering pump to a nebulizing stage then passed to a burner or the like from which the materials are converted into appropriate soots. The soots are then applied to a starting member which is subsequently subjected to heat to fuse it into a drawing blank.

  • Method and apparatus for detection of inclusions in glass article or the like
    Patent number: 4136961
    Abstract: An automatic system for scanning a generally cylindrical member with a thin beam of light. Detectors are provided for sensing interruption or scattering of the light beam by inclusions within the member. When an inclusion is detected transverse scanning stops and the beam is fixed along a chord of the cylinder. The cylinder is then rotated to cause the inclusion to intercept the chordal beam, and the information thus generated is used to identify the type and position of inclusions within the blank.

  • Parabolic reflector including filament locating means
    Patent number: 4125890
    Abstract: A generally concave reflector member is provided with three or more bosses having flat outer surfaces. The surfaces define a plane perpendicular to the axis of the parabola so that specific points within the parabola can be located with great precision. By using the bosses as reference points, lamp filaments can be accurately placed within the lamp structure, regardless of variations in the reflector member which occur during the manufacturing process.
