Mining | In ore dressing, smelting, and refining, a person who melts and fumesantimony in oil-fired kettles to make antimony oxide. (references) |
Occupations | Controls reactor vessels to polymerize raw resin materials to form phenolic, acrylic, or polyester resins: Pumps specified amount of raw material into calibrated tank according to formula and transfers materials into reactor. Starts mixers and pumps reagents and catalysts into reactor. Starts circulation and vacuum pumps. Adjusts valves to regulate flow of preheated or cooled fluid around jacket of reactor and to start and regulate polymerization reaction. Adjusts valves to regulate pressure and temperature in reactor. Tests viscosity and pH of resins to determine length of polymerization time, using pH meters and viscosimeters. Turns valves to discharge processed materials from kettles into cooling pans. Records processing time, pressure, temperature, and test results in log; and writes daily reports on amounts of raw materials used and finished product barreled or stored. May dump compounds into polymerized resins to thicken product. May pump polymerized resin from storage tanks to tank trucks or cars for shipment. May cast liquid plastics in molds. May analyze sample of plastics materials to determine clarity, acidity, fusibility, or brittleness, using slide rule, torsion balance, and other testing equipment. (references) |
| Controls automatic or semiautomatic equipment to polymerize solutions in reaction kettles to produce synthetic-rubber polymers, such as silicone or neoprene, following written specifications: Weighs solid or liquid chemical additives, using balance or floor scale. Dumps ingredients into kettle, using overhead hoist. Turns valves to load kettles with monomer, catalyst, and modifier solutions. Starts agitator and turns steam or water valves to activate and control polymerization. Observes and records dial and gauge readings, and draws and tests samples to determine degree of completion of polymerization. Turns valves to release vacuum and to cool batch to terminate polymerization. Starts pumps to transfer nonreacted materials to rerun tank. Flushes kettle with water and changes filter socks, or cleans kettle, using brushes and cleaning solvents. May remove reactor cover and manually dump catalyst in reactor. (references) | |
| Tends oil-fired kettles that melt and fume antimony to make antimony oxide: Charges antimony crystals into melting kettle with hoist, and fires burners. Regulates temperature according to thermometer readings and color and appearance of metal. Skims slag from surface of kettle. Connects trough from melting to fuming kettle, and pours metal into trough by tilting kettle. Heats metal to specified temperature to vaporize antimony which is drawn to baghouse and condensed as oxide dust. Fills buggy with antimony oxide from hoppers, and weighs filled buggy on floor scale. Empties buggy onto conveyor leading to rotating drum in which oxides from different charges are blended. Transfers blended dust to conveyor leading to automatic bagging machine. Determines antimony content by casting sample into rod of specified size, weighing it, and referring to standard chart. (references) | |
| Controls equipment to cook grain mash and boil resulting liquor (wort) with hops to flavor it preparatory to fermentation, following written or oral specifications: Mixes and cooks specified amounts of malt, corn, and rice in water, maintaining temperatures for designated periods of time. Turns valves to transfer mash to lautertub to strain and extract wort, and to control flow of wort from lautertub to brew kettle. Adds specified amounts of hops to wort in brew kettle and cooks mixture [KETTLE TENDER (beverage)]. Drains wort through hop-extractor into hot-wort tank and starts pump to transfer wort to cooler. May add hop extract to mixture in brew kettle. (references) | |
