sold under the trade name Nevillac. This series of plasticizing oils and resins range from viscous oils to hard resins and from pale amber to amber in color. They are soluble in almost all liquids except water, glycerols and the higher polyhydricalcohols, and compatible with most synthetic and natural resins including cellulose esters and ethers, vinyl acetate, vinyl butyral, zein and nylon. They are easily emulsified. The Nevillacs are used in the manufacture of adhesives, paper coatings, paints, varnishes, inks, artificial leather, stripping compounds, and in products requiring plasticizers having low voialilify and a wide range of compatibilities and solubilities.

RESEARCH SWRI Gets Lab Addition A mounting demand for research in the field of mechanisms has forced Southwest Research Institute to provide n e w and larger quarters for its mechanical laboratory. Under the direction of Charles E. Balleisen, research specialist Ln automatic machinery a n d kinematic synthesis, the new laboratory', now being fully equipped, is set up to make basic determinations of strength, dimension, and motion, and to study industrial machinery and manufacturing processes. To perform this work the laboratory equipment includes a high speed motion picture camera, various types of static and dynamic testing machines, a n d precision measuring instruments accurate to millionths of an inch. T h e laboratory is undertaking programs to analyze mechanical processes leading to improved production methods, applying quality control methods to inspection problems, a n d developing both full scale equipment a n d functional models.

NYU Has Acetylene Research Project Prof. John Kappel reads the dials as Prof. Charles Marsel of the chemical engineering department, New York University college of engineering, adjusts controls during preliminary tests on a pilot plant Hypersorber unit for purifying acetylene. This unit is part of an over-all research project covering acetylene production, purification, and utilization. It is believed that acetylene and acetylene chemicals can b e produced more economically by this method than by standard calcium carbide process Manufacturers' Association and cooperat ing agencies. T w o ice manufacturers are serving with W . R. Woolrich, dean of the engineering school, on a special advisory committee for t h e project. Graduate Student G u y Z. Moore of San Augustine will assist in the study.
N a v y G r a n t s Funds For Research on Burns Ten universities and medical schools have received funds from the Navy De partment to carry out a new program oi research on flash burns which might re sult from exposure to an atom blast. T h e new program, sponsored by the Office of Naval Research, will encompass the chemical, physiological, and biophysi cal aspects of burns. All distortions of natural processes of the body, such as might occur in the wake of blasts, will come under investigation. From the rcseareh, it is hoped, will emerge new means of protecting military and civilian person nel from b u r n injuries and new methods of treating flash burn casualties.

THE CHEMICAL WORLD THIS WEEK Raw M a t e r i a l s A v a i l a b l e For T e x a s Ceramic i n d u s t r y Discover)' of raw material sources of sufficient magnitude to make San Antonio a ceramic manulactunng center, as well as to permit development of a sizable mineral processing industry in south Texas, has been reported b y Southwest Research Institute. These facts came to light upon completion of a six-month preliminary survey of the area's ceramic production potentials by the institute's mineralogy department. Authorized by a city government bureau, the surve'v was conducted by John F u n nell. Among facts uncovered by the ceramic engineer "were the existence of substantial quantities of kaolin, plastic clays, talc and feldspar in die immediate San Antonio area. La"boratory tests showed the kaolin compared favorably with Georgia kaolins imported into Texas.
