Î University of Arkansas Section Gets PR Award The University' of Arkansas Section is this year's winner of the Local Section Public Relations Award. Here, M. H. Arverson, a national director of ACS, presents the award to Lowell F. Bailey, chairman of the section's science educa­tion committee. The section has been active in encouraging high school science education. When it learned that the high school in Fayette ville, Ark., lacked laboratory facilities, it set u p a committee which consulted with the school offi­cials and drew up plans for a lab. These plans were presented to the school board, and funds were allocated to outfit both biological and phvsical science labs. Now, the section has helped get labs under way for three more schools. The section has also been active with many other public relations projects.

"^ v. JEFFERSON CHEMICAL'S ETHYLENE CARBONATE PROPYLENE CARBONATE SS^fe MINIMUM PURITY

Jefferson has been a leader in the commercial devel­opment of these alkylene carbonates and, in order to meet the growing demand for these highly versatile materials, now maintains a minimum inventory of 10,000 pounds of each. The purity of both products

J u m u i i i c d α ι ν available o n three weeks' notice. These carbonates possess outstanding solvent prop­erties for numerous polymeric and other relatively insoluble organic compounds. Their miscibility with many common solvents suggests selective or extrac­tive solvent applications. Carbamates are formed easily with ammonia and ali­phatic amines, leading to applications in agricultural chemicals, plasticizers and resins. To effect alkoxy-lation, ethylene carbonate and propylene carbonate can b e frequently substituted where the respective oxides are inconvenient to handle. Because of its ability to produce carbon dioxide si­multaneously with its reaction with many different substances, ethylene carbonate may find application as a blowing agent for plastic or eiastomeric compo­

sitions. The low viscosity, high boiling point, and low freezing point of propylene carbonate suggest its use in hydraulic and other functional fluids. Samples of ethylene carbonate and propylene carbon­ate will be supplied on request. Write for Jefferson technical bulletins on these carbonates to Jefferson Chemical Company, Inc., 1121 Walker Avenue, Houston 2, Texas.

Constant uniformity iin every grade of Celite assures consistent results, less down- t ime

For mineral f̂ Ser use—Super Floss grade is made up of carefully sized fines air-floated off in the bag house.

•Pypical J-M bag house equipment.

A s THE MICROSCOPE SHOWS, each grade of Celite* diatomite has its own distinctive particle size dis­tribution. Yet no matter where or when purchased, each remains uni­form from bag to bag—your assur­ance of top production results with minimum down-time.

Three examples of flux-eaicined Celites are shown here. Hyflo® Super Cel is widely used for filtra­tion in many industries. I t has just the right combination of coarse and fine particles t o assure optimum clarity and flow rates. Celite 545, with a higher percentage of coarse particles, is used to achieve maxi­mum clarity and faster flow rates with liquids tha t have larger sus­pended particles.

Super Floss, one of several bag house grades, has fine particle size distribution. A white powder, it is processed within very narrow toler­ances (2-4 microns). I t is a popular mineral filler in fine products such as silver polishes.

Johns-Man ville can precision-produce so many different grades of Celite because it mines the material from the world's largest and purest commercially available deposit. For assistance with specific filtration or mineral filler problems, talk to a nearby Celite engineer. Or write direct to Johns-Man ville, Box 14, New York 16, Ν . Υ.

This plastic radome houses a radar antenna constantly scanning the skies to detect the presence of a i rcraf t . A line of these radars provides early warning of any threatening approach to the North American cont inent .

The Distant Early Warning Line is now on perpetual guard duty. Spanning the Arctic from Baffin Island to Alaska, this great system was conceived at the Lincoln Laboratory of M. I .T. and produced under the leadership of Western Electric.

But first the DEW Line had to be engineered into a workable system. This was done at Bell Telephone Laboratories.

The obstacles were formidable. Conventional means of communication —telephone poles, cables and even line-of-sight microwave radio —weren't feasible. A complicated system had to be made to operate reliably in a climate so cold that outdoor maintenance is impracticable farther than a few hundred feet from heated habitation.

Whenever possible, Bell Laboratories engineers utilized well-proven art. But as it became necessary, they innovated. For example, they designed and directed the devel­opment of a new and superior radar which automatically scans the skies, pinpoints a plane and alerts the operator.

To reach around the horizon from one radar station to another, they applied on a massive scale a development which they pioneered —transmission by tropospheric scatter. Result: at a DEW Line Station you can dial directly a station more than a thousand miles away and converse as clearly as with your home telephone.

Bell Laboratories ' contribution to the DEW Line demonstrates again how telephone science works for the defense of America.
