摘要:
A method for coating glass gobs (30) with a liquid-based lubricating dispersion during their drop, preferably in free fall, to blank glass container molds (34), which provides sufficient lubrication to the glass container molds without requiring swabbing of the glass container molds. The lubricating dispersion may comprise a solid lubricant having a d 90 of below 150 mm, and in particular may comprise graphite.

An apparatus for forming a lubricant layer on the surface of a glass prevents scratches from occurring at the surface of a glass and decrease corrosion of glass manufacturing equipment and may be included in an annealing furnace or a glass manufacturing apparatus. The apparatus includes a SO 2 supply unit for supplying SO 2 gas, a O 2 supply unit for supplying O 2 gas, and a catalyst retaining unit for retaining a SO 2 gas oxidation catalyst, the catalyst retaining unit receiving SO 2 gas and O 2 gas from the SO 2 supply unit and the O 2 supply unit to generate SO 3 gas and supplying the generated SO 3 gas to a glass.

摘要:
A burner (16, 116, 216) of a surface-mixing type receives a carbonaceous fuel, for example, an acetylene-based fuel, from a fuel line (20) and an oxidant, such as relatively pure oxygen, from an oxidant line (18), the oxidant being supplied to the burner at a rate insufficient to result in complete combustion of the fuel, to thereby produced a sooty flame that is useful in applying lubricating soot particles to a molten glass contacting surface of a glass manufacturing machine. The burner, which is intermittently operated by a solenoid valve (38) in the oxidant line and by a solenoid valve (40) in the fuel line, has a fuel inlet passage (60) that extends along a longitudinal central axis of a tip element (56) of the burner, and an annular inlet passage (64) that surrounds the fuel inlet passage. The fuel inlet passage, which is otherwise closed at its downstream end, terminates in a multiplicity of separate passages (62) that are arranged in an annular array and through which fuel exits from a burner tip in an annular pattern on an interior of oxidant exiting from the burner in an annular pattern through a passage (66) in an annulus between the tip element and a cap element (58) of the burner. The burner serves to ensure rapid mixing of the fuel and oxidant streams downstream of the burner, to thereby rapidly form an ignitable mixture that can be ignited by a spark igniter (54). 2-way solenoid valves (38, 40) are provided in the oxidant and fuel lines, respectively, to permit the burner to be operated intermittently.
摘要:
A die for press-molding glass optical elements which can press-mold glass optical elements having high melting points and various shapes repeatedly, which includes a base material 11 having high strength on which a cutting layer 12 having heat resistance and free cutting machinability is formed. After cutting the cutting layer 12 into the desired shape with high accuracy, the die is coated with a surface protective film 13.
