This black and white film is one of a 1950-1960 television series Industry on Parade, produced by the National Association of Manufacturers. It contains four segments. “Kentucky.” The American Air Filter Company in Louisville is shown as an office full of desks and workers. The air is cleaned through a glass fiber filter mounted like a paper towel roll. The dirty section is pulled down to expose a new clean section. A worker shovels from a tall pile of glass cullet, obtained from automobile window factories. It is dried, melted, and formed into strands of glass thread, shown on giant rolls. When thick enough, it is pulled off in a sheet, stretched by hand, heat treated, and cut to size (:38-3:05). To make air filters, the frames are made from waste paper board and the metal grids are scrap from a bottle cap factory. The fiberglass is cut to size and manually inserted into the frame. A label is hand-applied. A very long air filter is inserted at a hospital and smaller ones in the attic of a house by a woman wearing a 1950s head scarf. Children in 1950s clothing sit and play with metal cars and trucks (3:06-4:56). “Pennsylvania.” At the Midland Works Crucible Steel Company of America, Ronn straddle carriers and forklifts are used to move and stack heavy steel beams (4:57-7:33). “Connecticut.” Women workers at Waterman Pen Company in Seymour handle ink cartridges for fountain pens as they move on a conveyer. Another group hand-assembles the many parts that make up a fountain pen. The pen point, ink reservoir, and feed are heat molded together. The proper tension is put on the tines of the pen point by hand. Each pen is tested without and with the ink cartridge. Researchers are shown in its laboratory testing new inks. Writing machines test the life of an ink cartridge. Women package the final product of pen and cartridges into a boxed set on a moving conveyer (7:34-10:39). “Michigan.” A radio engineer uses a screwdriver, a stenographer wears a 1950s dress with large white collar lapels and cuffs, and a large flower pin. Adult students take part-time classes at Michigan State College’s educational TV station WKAR TV station. A desk top has multiple skulls and jaws on it, shown being filmed as an episode for an Anthropology class. The Professor takes it to a student for handling. The class is viewed by students at home on a flickering television. Final tests are administered at the College (11:20-13:10).
