Occupations | Controls continuous-treating or batch-treating equipment to process petroleum products, such as gasoline, kerosene, and lubricating oils, with chemicals, solvents, steam, clay, and hydrogen to remove impurities and to improve color, odor, and stability, according to specifications: Moves and sets levers, switches, dials, and handwheels to admit products and treating agents to processing units in specified ratio; to direct flow of products through treating stages, such as mixing, precipitating, and neutralizing; and to regulate temperatures, pressures, and circulation rates of treating equipment. Observes temperature gauges, pressure gauges, and flowmeters; records readings; and compiles operating records. Patrols unit to detect malfunctions and leaks. Opens bleeder valves to sample products and tests them for chemical characteristics, specific gravity, and color, or sends sample to laboratory for analysis. Reprocesses products or pumps them to storage tanks, according to test results and laboratory recommendations. Opens valves to drain sludge from units. May repair and lubricate equipment. May treat products, using hydrogen-catalytic process. May operate refrigerating equipment [REFRIGERATING ENGINEER (any industry)]. May add dyes or fortifying chemicals to product [BLENDER (petrol. refin.)]. May be designated according to product treated as Crude-Oil Treater (petrol. refin.); Wax Treater (petrol. refin.); treating agent used as Acid Treater (petrol. refin.); Hydrogen Treater (petrol. refin.); plant operated as Clay-Plant Treater (petrol. refin.); Naphtha-Plant Treater (petrol. refin.); Solvent-Plant Treater (petrol. refin.); or type of operation as Batch-Unit Treater (petrol. refin.).

| Controls oven, humidifier unit, and auxiliary equipment to temper pressed hardboard by heat and moisture: Observes gauges and chart recorders on instrument panel and adjusts controls to start fans, set oven temperature, and regulate moisture conditions in humidifier unit according to plant specifications. Tends machine that immerses hardboard sheets in oil to impart smooth finish on both sides. Pushes hardboard sheets to be tempered onto roller conveyor leading from oiling machine to tilting device that dumps sheets into electric transfer cart. Drives loaded cart to oven. Pulls overhead wire to position loaded cart in oven to cure board. Drives cart from oven to humidifier unit after prescribed time and back to tilting device for unloading board after tempering. Starts mechanism that dumps tempered board from cart. Inspects board for defects, such as scratches, streaks, and discoloration. Verifies adherence of board to specifications, using viscometer to determine resilience of sheet to known stress, and coating machine that applies varnish to board surface to test sealing qualities of finish. Delivers samples of tempered board to control laboratory for exhaustive testing. Keeps records of gauge readings, test results, and shift production. Labels ticket attached to each lot of tempered board to facilitate work of inventory control and shipping personnel. (references) | |
| Controls one or more cylinder retorts to impregnate wood products, such as railroad ties, piling, telephone poles, and fenceposts, with preserving or fireproofing chemicals: Turns valves to admit treating solution into retort and steam into heating coils. Presses buttons to activate vacuum- and hydraulic-pressure pumps that remove air and steam from retort and force treating solution into pores of wood to accelerate treatment process. Observes gauges and turns valves to maintain specified heat, vacuum and hydraulic pressure, and level of solution in retort during each phase of treatment cycle, according to treating schedule. Pumps treating solution back into storage tank at end of treating cycle. Opens, or signals TREATING-ENGINEER HELPER (wood prod., nec) 561.685-010 to open, retort doors. Heats unseasoned wood in retort to remove moisture preparatory to treating process. May operate locomotive or winch to move tram loads of wood products in and out of retort. May take and test sample borings, using laboratory equipment, to determine if treatment meets customers' specifications or standard chemical-analysis requirements. May be required to hold license.
