Title: Casting and stretching during manufacture of medical x-ray film
Date(s): 1955, 1955~
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: Molten polymer enters one end of this 300 foot long casting and stretching machine and emerges as a continuous sheet of Cronar polyester film base for medical x-ray film at DuPont's new Brevard, North Carolina plant. On its way through, the film base is stretched longitudinally and laterally to about 10 times its original size, inspected and wound on large mill rolls. The rolls are then stored to await emulation coating and finishing, The operator in the foreground is making precise...

Title: Brevard plant
Date(s): 1955, 1955~
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: The nation's first full scale plant for the manufacture of hyper pure silicon constructed by the DuPont Company at Brevard, North Carolina. Silicon, developed by the DuPont for use in radar during Worked War II, is a vital raw material in the electronics industry. Located at the western tip of North Carolina, the 10,500 acre plant offers protection against air borne contamination from industry or agriculture. Since impurities in silicon are measured in parts per billion, extremely pure air is...

Title: Making medical x-ray film
Date(s): 1955, 1955~
Contributor(s): E.I. du Pont de Nemours & Company (originator)
Description: Medical x-ray film is made in wide mill rolls at DuPont's new plant at Brevard, North Carolina. It is then slit into desired widths under safe light conditions on machine like this. A single mill roll will contain over a mile of film, slit rolls are inspected, cut into sheets and packaged for shipment. At the Brevard plant, DuPont manufactures only X-ray film. At other locations it makes motion picture, graphic arts and drafting films; photographic papers; chemicals and other photographic...

Description: Operator at DuPont's new silicon plant at Brevard, North Carolina 'picking' silicon needles. This method of inspection helps maintain high purity standards of DuPont silicon. The material, a non metallic element, is used in such devices as transistors, diodes and rectifiers, which in turn are used in manufacturing more compact, more efficient communication and electronic equipment. While silicon and its compound are well known in the industry, it is the pure element developed by DuPont...
