Abstract: The elongated burner is described which is capable of providing a ribbon of flame through which particulate material as small as 1 micron is uniformly dispersed and transported onto a rotating forming surface for formation of an ingot. In a preferred embodiment the burner is provided with a hollow interior defined by a cylindrical surface interrupted by a longitudinal groove in communication with a longitudinal discharge slot. The sides of the groove are sloped at an angle steeper than the angle of repose of the particulate material. In the preferred embodiment the exterior surface of the burner is likewise provided with a longitudinal groove in communication with the discharge slot and providing two surfaces angled toward each other and toward the path through which the discharged material travels. At least one linear array of orifices is spaced along each of the angled surfaces so that flame emanating from the orifices in one angled surface will converge with the flame emanating from the orifices of the opposite angled surface at a point within the path of the discharged material.

Abstract: The invention relates to a glass lathe for producing preforms which may be drawn into energy transmitting fibers. The apparatus includes a head stock and a tail stock for rotatably holding a starter tube and the preform as it is built from the starter tube. The tail stock is movable along the lathe bed with respect to the head stock so that a preform may be drawn down to approximately the diameter of the starter tube. A carriage is provided on the lathe bed which carries at least one burner for melting a particulate quartz feed and depositing it onto the rotating surface of the starter tube. A slide member mounted on the carriage supports a container for catching particulate quartz which does not adhere to the tube and a coolant reservoir adapted to produce a fountain for contacting and cooling the tube downstream of the burner. Layers of silica and doped silica are first deposited on the tube interior by introducing reactant vapors into the tube interior while traversing the length of the starter tube with the burner. Subsequent to the internal deposition step, the OD of the tube is built up by deposition of successive layers of fused quartz by feeding particulate quartz through the burner flame onto the rotating outer tube surface. After building the tubular preform to suitable diameter, it is drawn down to approximately the OD of the starter tube and cut into suitable lengths for use as preforms.

Abstract: The disclosed invention provides method and apparatus for the separation of diamagnetic and paramagnetic particulate material. The invention utilizes a magnetic roll formed of either alternating permanent magnet and nonmagnetic spacer disc elements or alternating saperdisc elements and disc elements in which magnetism is induced. The dry admixture to be separated into magnetically homogeneous fractions is fed as a plurality of discrete streams onto spaced points on the upper surface of the rotating roll. The feed material undergoes lateral separation on the face of the roll and the materials of different properties part from the surface of the roll at different angular positions, thereby enabling their separate collection. For this purpose a plurality of receptacles are provided in a horizontally spaced relationship to collect the individual streams of diamagnetic material as they leave the surface of the rotating roll. In the preferred embodiments the streams of diamagnetic material off of the last roll pass through a high voltage field whereby they undergo an electrostatic separation.

Abstract: The disclosed process separates impurities, including admixed minerals other than quartz and quartz particles having relatively high levels of lattice impurities, from a quartz containing particulate material to recover a high purity quartz product. The process involves treatment with a solvent to reduce the size of the impurities relative to the quartz product and the thus treated material is then classified by size to recover the purified product. If impurities less soluble than the quartz product are also present, a second solvent treatment is conducted to reduce the size of the quartz particles relative to the less soluble impurity and a second classification by size is conducted. In a preferred embodiment, the quartz is subjected to a heat/quench cycle to fracture quartz particles thereby exposing occluded and interstitial impurities to the solvent leach. The intermediate product exiting the final solvent treatment and classification steps is dried, blended and roasted in a vacuum to remove gases.

A feeding device introduces the SiO.sub.2 feed through the open bore of one of the electrodes for melting by the plasma arc.

Abstract: A high pressure reaction vessel has a container portion and a removable head portion which houses a flow channel or channels, valve members and valve operators and which seals and covers the container portion. Each channel terminates at a tapered valve seat angled at at least 36.degree. with respect to the horizontal and each of the valve members is provided with a mating tapered surface which is wedged more tightly within the valve seat as pressure within the vessel increases. A port and a chute are provided for introducing a particulate solid feed through at least one of the channels into the interior of the vessel. In one embodiment a dip tube depends from a second valve seat (in communication with a second channel) and extends to a point adjacent the bottom of the container portion. In the preferred embodiments the head portion is surrounded by a removable flange having a central tapered opening and is in the form of a plug member in which the channels are formed and which carries the valve seats, valve members and valve operators. The circumference of the plug member is tapered to mate with the tapered surface of the removable flange in such a way that increasing pressure within the vessel enhances the seal between the plug member and the central opening of the removable flange. In one embodiment the body portion of the reaction vessel is provided with a liner of a halogenated hydrocarbon resin which extends upward to a seal between the tapered surfaces of the plug member and the central opening of the removable flange and is pinched more tightly therebetween as pressure within the vessel increases. In another embodiment the liner is tubular and similar removable flanges, with mating plug members, are provided at the top and the bottom of the container with a wedged valve and valve seat providing for solids discharge through the bottom plug member.
