ETHYL CORPORATION CUTS TEL TEST TIME WITH G-E X-RAY PHOTOMETER
G-enera.1 Electric's X-Ray Pho tometer has enabled Ethyl Corpora tion, Yonkers, Ν. Υ. to cut time and expense in determining the tetraethyl lead (TEL) content of gasoline. Previous standard methods of anal ysis require three hours to complete, i n c l u d i n g 20 minutes of operator time; whereas the G-E X-Ray Pho tometer requires only 15 minutes for the entire test. The rapid analysis possible with the X-Ray Photometer has enabled closer control and has freed the chemist from routine work. Sturdy shielding and interlocks provide adequate protection for the operator. The General Electric X-Ray Photom eter has maintained high accuracy of results, and the test is non-destruc tive in nature.
NAVAL RESEARCH LABORATORY STUDIES SURFACES WITH G-E ELECTRON DIFFRACTION INSTRUMENT The U.S. Naval Research Labora tory, Washington, D.C., finds a wide variety of experimental applications

for the G-E Electron Diffraction Instrument. In operation for approxi mately two years, the instrument enables the Laboratory to conduct studies and experiments on all types of surfaces. With the General Electric Elec tron Diffraction Instrument, surface studies of corrosion, and organic film adsorption are made, leading to the development of new materials by the Lubrication Branch ot the Chemis try Division. This is one of the units used at the Naval Research Labora tory at this time (left). A leading feature of the instru ment is its large specimen chamber. This makes it unnecessary to cut up specimens. Testing is non-destructive and valuable samples are preserved. The unit enables the study of systems at various stages of the experiments. Great versatility is achieved by variable beam voltage, which can be adjusted to a maximum of 50,000 volts. The Naval Research Labora tory finds it advantageous to operate at 35,000 volts, for their work.

ESSO INSTALLS A G-E MASS SPECTROMETER
Operator inserts test cell in X-Ray Pho tometer at Ethyl Corporation, Yonkers, New York.
A t the Esso Research Center, Linden, NT. J., t h e G-E mass spectrometer has proven valuable in t h e solution of difficult analytical problems a r i s i n g in connection w i t h petroleum processes, products and derivatives. Advantage is t a k e n of its h i g h resolving power in t h e analysis of a wide variety of materials. Direct recording is a very useful feature.
DEWPOINT RECORDER CHECKS MOISTURE FOR CHRYSLER AIRTEMP Better moisture control of air used for drying refrigerator coils, has been achieved with a G-E Dew point Recorder, installed at Chrysler Airtemp Division, Chrysler Corpora tion, Dayton, Ohio. Large dehydrating equipment sup plies dry air for this operation. With
the Dewpoint Recorder, a continuous check and permanent record is kept of the moisture content of the air before it enters the coils, resulting in savings in material and labor. The G-E device replaced a test which was slow and used large amounts of C0 2 -
