JfcePutmeHfrï Ν EWS ETHYL CORPORATION CUTS TEL TEST TIME WITH G-E X-RAY PHOTOMETER General Electric's X-Ray P h o t o m e t e r h a s enabled Ethyl Corpora t i o n , Yonkers, Ν . Υ. to cut time and expense in determining the tetrae t h y l 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 m i n u t e s of o p e r a t o r t i m e ; whereas t h e G-E X-Ray P h o t o m e t e r requires only 15 minutes for the entire test. T h e rapid analysis possible w i t h t h e X-Ray Photometer has enabled closer control and has freed the c h e m i s t from routine work. Sturdy shielding and interlocks provide adequate protection for the operator. T h e General Electric X-Ray P h o t o m eter has maintained h i g h accuracy of results, and t h e 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, W a s h i n g t o n , D . C . , finds a w i d e variety of experimental applications

for t h e G-E Electron Diffraction Instrument. In operation for approxi mately t w o years, the instrument enables t h e Laboratory to conduct studies and experiments on all types of surfaces. W i t h t h e 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 of the Chemis try Division. This is one of t h e units used a t the Naval Research Labora tory a t this time (left). A leading feature of the instru ment is its large specimen chamber. This m a k e s it unnecessary t o cut up specimens. Testing is non-destructive and valuable samples are preserved. The unit enables t h e study of systems at various stages of the experiments. G r e a t versatility is achieved by variable beam voltage, w h i c h can be adjusted t o a maximum of 50,000 volts. T h e Naval Research Labora tory finds i t advantageous t o operate at 35,000 volts., for their w o r k .
