New thermodynamic data center formed
130 GE GETS EPRI CONTRACT TO DEVELOP SUPERBATTERY A $2.5 million, 32-month contract for developing a superbattery that could be used by the nation’s electric utllltles for bulkenerav storaae has been awarded to the GenGal Electric Research and Development Center by the Electric Power ‘Research Institute. The objective Is to develop a recharge able sodium-sulfur storage battery that potentially offers five times more storage capacity per pound than a standard lead-acid battery. Scientists hope to develop a unit about the size of a file drawer with a storage capacity of about 10 kWh of electricity. Addltlonal testlng Includes assembling several of these units Into a desk-elzed module capable of storlng more than 100 kWh. . Excess energy could be stored durlng periods of low usage and discharged at times of peak demand to make more efflclent use of a utility’s generating capacity.

NEW THERMODYNAMIC DATA CENTER FORMED The U.S. Geological Survey has establlshed a National Center for Thermodynamics Data of Minerals. It will acquire and provide, on a continuing basis, critically evaluated descriptions of the thermodynamic properties of minerals and other geologic materials at tempe ratures, pressures and composltlons observed in the geological environment.

He was responsible for the establishment of the High Temperature Materials section in 1968, and Is now a vice-chairman of this section in the Ceramic Society of Japan. He was honored to receive the Basic Ceramic Award from the Ceramic Sot. of Japan in 1972. He stayed, as an exchanae research worker -at C.N.R.S.. BelIeGe. in France in 1964- 1965 and visited 20 countries including Sovlet Russia. Con. tinental China, and Korea. Dr. Sata _is the author or cc-author of over 100 papers, and 2 books. His research area was on catalysts for oxidatlon and polymerlzatlon till 1945 and then it extended to include basic re fractories (dolomite, magnesia, magne sia chromitej for fused phosphate fertilizer and steel manufacturing. oxlde cermets, and uranium-thorium oxide nuclear fuel. His present basic research are on rare earth oxide materials, high temperature behaviour of oxide compounds, and amorphous ceramics.

A 2%inch (63.5 mm) diameter disc of Macor machinable glassceramic manufactured by Corning serves as the circuit base that is the heart of a new angle transducer In a surveylng instrument produced by Hewlett-Packard Co., Palo Alto, Calif. The parts made from Macor glassceramic are cut from bar stock with conventional metalworking tools in onetenth the time It takes to form and flnlsh the other materlals. Previously, the part might have been made from alumlna or beryljia In a time-consuming. costly process that involves casting or pressing in a mold, then grinding and polishing to a desired flatness.
OPTICAL WAVEGUIDES USED IN AIR FORCE’S DATA-CARRYING CABLE Optical waveguldes made by Corning are an essential part of a cable Installed at the U.S. Alr Force Arnold Engineering Development Center In Tennessee. The cable contains six waveguldes, along with several copper conductors. Each waveguide may be employed independently for transmitting, at high-speed, data signals or any other information, including voice and video slgnals. The waveguides transmit data from the englne test sltes to the base computer center, located approximately two kilometers away. The optical waveguldes were chosen for the installation because of their large datacarrylng capablllty. and because they are Immune to hostile environments. particularly electrome gnetic Interference. The cable consists of a welded tubular aluminum sheath surrounding the fibers and their support structure, a polyethylene inner jacket, a corrugated steel wrapping and a polyethylene outer jacket. The cable is suitable for installation in ducts or can be buried directly in the ground. The installation at the Arnold Center is particularly significant because it is intended as an operational system, not an experimental one. The complete
