  • Patent number: 10656024
    Abstract: A molten material apparatus can include a container including a wall at least partially defining a containment area and an opening extending through the wall. The molten material apparatus can include a protective sleeve mounted at least partially within the opening of the wall of the container. A thermocouple can be positioned within an internal bore of the protective sleeve. A method of processing molten material can include inserting a thermocouple into a protective sleeve fabricated from a refractory ceramic material, and measuring a temperature of material within a containment area of a container with the thermocouple.

  • Publication number: 20190161377
    Abstract: A method of melting glass and glass-ceramics that includes the steps: conveying a batch of raw materials into a submerged combustion melting apparatus, the melting apparatus having liquid-cooled walls and a floor; directing a flame into the batch of raw materials and the melted batch with sufficient energy to form the raw materials into the melted batch; and heating a delivery orifice assembly in the floor of the submerged melting apparatus to convey the melted batch through the orifice assembly into a containment vessel. The melted batch has a glass or glass-ceramic composition that is substantially reactive to a refractory material comprising one or more of silica, zirconia, alumina, platinum and platinum alloys.

  • Publication number: 20190101694
    Abstract: Methods of manufacturing multi-mode optical fiber, and multi-mode optical fiber produced thereby, are disclosed. According to embodiments, a method for forming an optical fiber may include heating a multi-mode optical fiber preform and applying a draw tension to a root of the multi-mode optical fiber preform on a long axis of the multi-mode optical fiber preform thereby drawing a multi-mode optical fiber from the root of the multi-mode optical fiber preform. The draw tension may be modulated while the multi-mode optical fiber is drawn from the root of the multi-mode optical fiber preform. Modulating the draw tension introduces stress perturbations in the multi-mode optical fiber and corresponding refractive index perturbations in a core of the multi-mode optical fiber.

  • Patent number: 9643871
    Abstract: A submerged combustion melter and burner therefor. The burner may include a first tube having a scaled distal end and a second tube concentric to the first tube, the second tube having a partially sealed distal end with an opening for receiving the first tube, where an annular space is defined between the first and second tubes. The burner further includes a first gas port in the sealed distal end of the first tube, the first gas port supplying a first gas, a second gas port in a distal end of the second tube, the second gas port supplying a second gas to the annular space, and a nozzle on the proximate ends of the first and second tubes.

  • Publication number: 20160060154
    Abstract: A burner for submerged combustion melting that mixes a first gas and a second gas inside the burner and emits the mixed gas through a nozzle for combustion below the surface of the material being melted. The burner includes a hollow tube and a static mixer inside the tube that mixes the first gas and the second gas as they travel through the tube. The mixed first and second gas exits a nozzle on a top end of the tube and is ignited to generate a flame below the surface of the material being melted, which may be a glass material.

  • Publication number: 20150291465
    Abstract: A swirling burner 100 for submerged combustion melting that swirls at least one of a first gas and a second gas exiting the burner. The burner includes a central tube for delivering the first gas a nozzle and an outer tube for delivering a second gas to the nozzle. Helical vanes or channels are provided in at least one of the central tube and the outer tube to cause a least one of the first gas and the second gas exiting the burner to swirl.
