Chicopee MA-Spring is here and hard on its heels is the season for baseball, Americas favorite sport. Already the factories that manufacture baseballs are busily turning out a supply to meet the demand. These photographs, made at the A.G. Spalding...
An engineering drawing, when microfilmed, takes up little space as pictured here in a visual comparison. The distance between two thumbs is the indicated measure of one frame.
A laboratory technician places a disc of Teflon tetrafluoroethylene resin, a DuPont industrial plastic, in a high voltage testing set to measure its dielectric strength. The transformer oil bath serves as an insulator to prevent voltage flash over...
This Geiger-Muller counter is mounted on a stand of Lucite acrylic resin. Described as the most sensitive instruments known to man, such counters measure the degree of radiation from radioactive substances. They were used widely in determining...
Recently designed and constructed by the DuPont Chemicals division is this new 'Raintester' which duplicates the effect of rain on garments and fabrics and makes it possible to measure their water repellent qualities. By adjusting the nozzle at the...
To determine the degree of gloss in a lacquer or finish, du Pont chemists use a device that measures the amount of light reflected. The light from a constant source is thrown back from the panel into the telescope tube. One half of the 'eyepiece'...
Mirrors are being arranged by DuPont research physicists preparatory to making preliminary studies in infrared microspectroscopy. The measure of light absorbed by a tiny sample will help determine the molecular structure of the material being...
Experimental tunnel at DuPont Company's plant at Pompton Lakes, New Jersey is used by Eastern Laboratory technicians to duplicate conditions in underground mines. Tunnel is drilled 100 feet into face of a stone cliff. It enables researchers to...
The Pioneering Section of the DuPont Company's Textile Fibers Department developed this equipment to measure the insulation value of clothing fabrics. It is one of the instruments in use at the company's Experimental Station near Wilmington,...
