written on back of print: "Studebaker 1942." typed on back of print: "Compact grouping of modern radio and Climatizer controls in center of the instrument panel adds carm to the 1942 Studebakers. Lever at center bottom is the Climatizer...
This afternoon for the first time Paris spoke to New York on the telephone when the service was opened at the office of the Minister of Commerce M. Bokanowski. He spoke to America at 3 pm this afternoon also did General Pershing and others. The...
The instruments in the control room at DuPont's Victoria Texas plant serve both as a reporter and regulator. A meter, for example, controlling the flow of a liquid sends a report to another device set to the required standard. A third instrument...
One of the instrument panels at the DuPont Company's Tecumseh, Kansas cellophane plant, which permits precise control of every step of the manufacture process of viscose, a syrupy liquid which is then converted in the casting process into clear,...
Illumination of the sinus is achieved by the use of Lucite acrylic resin in this surgical instrument. Lucite conducts very little heat. It therefore is ideal for surgical purposes. This is one of many surgical instruments made from the plastic...
A laboratory technician places a piece of Teflon tetrafluoroethylene resin, a DuPont industrial plastic, in an instrument which measures the plastic's dielectric constant and power factor at 3000 megacycles. Because its dielectric loss factor is...
A circular piece of Teflon tetrafluoroethylene resin, a DuPont industrial plastic, placed between tinfoil electrodes, is being measured for its dielectric constant and power factor at 60 to 15,000 cycles. A laboratory technician adjusts the...
By measuring the angle through which a beam of plane polarized light is rotated, the polarimeter makes possible of this instrument saves a great amount of time in analytical procedures. In this picture, a laboratory assistant records results of...
Highly ingenious laboratory tools and instruments help DuPont scientists uncover many secrets of nature ordinarily hidden from the human senses. This 'Breath meter' is so sensitive that mere blowing on the steel bar can easily be registered. This...
This photograph illustrates the wide variety of training and skill necessary to carry out research efficiently on the large scale on which it is conducted at DuPont's Experimental Station. Many specialists, in addition to research chemists,...
The exceptionally high magnification of the most modern type of electron microscope helps solve the research problems of industrial chemistry at the Experimental Station. Electronic images produced by magnetic �lenses� of this instrument reveal...
Ultracentrifuge in laboratory of DuPont�s Chemical Department a the company�s Experimental Station rotates solutions at such high speeds as to exert a centrifugal force 270,000 times the force of gravity. By use of this instrument, the physical...
