American Institute of Chemists was characterized by Mars ton T. Bogert as a man "who makes hay out of the grass that grows under the other fellow's feet" at a dinner given by the institute in his honor at The Chemists' Club, New York, on October 23. Speakers a t the dinner in addition to Dr. Egloff were: Robert J. Moore, Bakélite Corp.; George A. Burrell, Atlantic States Gas Co.; Robert E . Wilson, Pan-American Petroleum and Transport Co.; Marston T . Bogert, Columbia University; and H . J. Halley, Universal O i l P r o d u c t s C o . Ε . Η . Northoy, of the Calco Chemical Division of American Cyanamid Co. and chairman of the institute's N e w York Chapter, pre sided. Dr. Egloff, director of research of the Universal Oil Products Co., Chicago, looked into the future of petroleum prod ucts in an address entitled "Wartime Chemicals from Natural Gas". Synthetic tires having lives equal t o that of the ve hicle on which they are used, synthetic rubber a t a price which will ensure its permanent place in our economy, and many other vital products of natural hydrocarbons were foreseen b y Dr. Egloff as probable immediate outcomes of present research and development.

Training for Safety Auditors Π Π Η Β third class of safety auditors has begun work in the headquarters of t h e Safety & Security Branch, Office of the Chief of Ordnance, 333 North Michigan Ave., Chicago, 111., and includes eight women, the first to take explosives safety training in a class which also includes men. The intensive 6-week course prepares students to become explosives safety auditors in munitions and explosives plants.

At a recent meeting of the Associa tion of Iron and Steel Engineers, E. S. Harman, production manager of the Lof tus Engineering Co., said that his company a t the request of the War Production Board was preparing preliminary plans to con struct the country's first commercial plant to use a process which he developed. This plant, it is estimated, would produce six times as much scrap as the sponge iron produced by other means and would b e the only one with commercial possibilities as to capacity.

T h e RCA Electron Microscope now offers re search experts two different approaches to the mystery of sub-microscopic particles. First, it enables them to study physical appearances at magnifications never before obtainable. Sec ondly, it enables them to penetrate deeper, to peer into t h e atomic lattice itself and study the actual composition and structure. B y its inherent high resolving power making possible useful magnifications up to 100,000 diameters, the RCA Electron Microscope re veals details that furnish the scientist with invaluable clues. And by the use of an "adapter", it can quickly be converted

A c i d Treatment Shows Increase in Turpentine Yield C^OR some time the Forest Service of the U. S. Department of Agriculture has been experimenting with acid solutions applied directly to fresh streaks on slash pine trees immediately following chipping. The research work has been carried on at the Olustee Experimental Forest, 13 miles east of Lake City, Fia., where foresters found a 40 per cent solution of sulfuric acid most effective in increasing gum flow yields. At the beginning of this year's naval stores season, a number of private opera tors in Florida and Georgia cooperated in tests with the sulfuric acid solution on slash pine. Their records show an average increase of 25 per cent gum flow. These commercial tests, conducted for the pur pose of increasing turpentine and rosin yield for war needs, were sponsored by the Forest Service with the cooperation of the Agricultural Adjustment Agency. Foresters tried out more than 100 pos sible stimulants but sulfuric acid has given the best results. They are still attempting to improve on the sulfuric acid solution by conducting tests with some 40 substances that might possibly provide greater stimu lation. Experiments also are under way look ing to methods that will increase gum yield from longleaf pine as well as slash.
New Patented Rosin Process Available / ^ LEAN and brilliant rosin, unusually free ^ ^ from impurities, is possible through a new producing process for which a patent (U. S. Patent 2,295,235) has been issued to Jesse O. Reed, U. S. Department of Agriculture. The patent has been assigned to the Secretary of Agriculture. An essential part of the process is that the crude oleoresin is made "dry" or water-free by adding turpentine near the end of the normal distillation period so that the whole mass can be readily filtered through media of various types, including paper. B y driving out the water in the rosin, the inventor has found that impurities can be easily filtered out, with the result that the final rosin is clean and brilliant. The tur pentine added to the rosin to drive out the water need not be distilled off to produce a solid rosin, but may be retained to form a liquid product that can be handled in the same manner as other sticky materials. Persons in the naval stores industry who wish to use this new process should apply t o the Secretary of Agriculture for a license. Further information may be ob tained b y writing to the Naval Stores Division of the Bureau of Agricultural Chemistry and Engineering, United States Department of Agriculture, Washington,

Awards for War Production T P H E International Nickel Co. plant at Huntington, West Va., has received its third war production award, giving it the right t o fly the Army-Navy " E " with two stars. The Army-Navy Production Award has been presented to the Victory Plastics Co., which makes a scabbard of Tenite, for high achievement in the production of war materials. On September 25 Rear Admiral E. J. O'Brien, chief of the British Admiralty Technical Mission, paid tribute t o the part which employees of The Foxboro Co. are playing in war production. John T . Nevitt, Jr., has received the first-prize war bond in a productionslogan contest for employees of Leeds & Northrup. His slogan was "V Depends on Me". Tube-Turns, Inc., was the first company in the state of Kentucky to receive the Army-Navy " E " , at a ceremony which took place on September 18. The September issue of Kodak is de voted to an account of the presentation of the Army-Navy Production Award to the Eastman Kodak Co. Receipt of the Army-Navy " E " by the Rustless Iron and Steel Corp. of Balti more, Md., has focused attention on the company's special process which enables use of submetallurgical grade chromite in the making of stainless steel, resulting in savings of chromium and nickel nearly 5 0 per cent greater than those obtained with other processes.
Presentation of the Army-Navy "E"*flag to the American Machine & Metals, Inc., East Moline, 111., was made on October 1. The company doubled its original pro duction quota of 20-mm. antiaircraft gun mounts and exceeded quotas on other war items. The seventh and eighth awards of an Army-Navy " E " to plants owned or operated by the du Pont company for outstanding accomplishment in produc tion of war materials were made jointly on November 6 to the local plants of the Electrochemicals Department and the Chemical Warfare Service.

Steel and Wire Reinforce Conveyor Belt Although apparently no different from any other conveyor belt, this section of a new belt for the Olive Iron Mining Co. in Duluth, Minn., actually represents an epochal advance for belts of this type in that it has a steel-wire carcass instead of the con ventional cord or fabric carcasses. It was developed by the Goodyear Tire & Rubber Co. of Akron, Ohio, to speed the flow of iron ore to the nation's war-humming mills, in addition to other tasks where extra-strong belts are required for the war effort CHEMICAL
