Four engineering drawings for an in-plant vacuum dust cleanup system for "All Plants": a material list and system ratings (drawing 30386-4) and two sheets of "Typical Methods, Dust Disposal" (30384-4 and 30385-4), drawn by Vigneron at the Johns-Manville Products Corporation Research and Engineering Center in Manville, New Jersey, and dated August 30, 1972, with a fourth drawing of the "Dust Trap, Vacuum System." They show vacuum stations with floor hoses feeding a dust trap and blower, with the collected dust discharged by rotary valve to the plant's dust collector or to a steel barrel with a plastic liner.
