A Series for Chemists and Executives of the Solvents and Chemical Consuming Industries
Ralph Knight Appointed U.S.I. Vice President Ralph M. Knight, Manager of Polyolefin Planning for U.S.I., was recently appoint ed a Vice President. In his new position, Mr. Knight will inten sify U.S.I's long-range polyolefin develop ment p r o g r a m , lie will continue to direct the Polymer Service Lahoratory as well as to coordinate ils efforts with other plastics activities within the company. The newly created post is a reflection of the expanding role of polyolefin plastics in U.S.I.'s long-range growth plans. U.S.I, is currently the country's third largest producer of poly ethylene, which it markets under the trade name PETROTHENB®. The company has under way an extensive expansion program which is expected to make it the second largest pro ducer of polyethylene in the world by mid1960. Since joining the company in 1953, Mr. Knight has served as Polyethylene Manager, Polyethylene Production Manager, Assistant to the Vice President for Production, and Manager of Polyolefin Planning.

Comprehensive Study Provides Data o n Corrosion Resistance of Commercial Titanium-Base Alloys Alloys Generally Corrode More Than Commercially Pure Titanium An intensive research program to determine the corrosion resistance of seven of the most commonly used titanium alloys has recently been completed. Results indicate that in strong acids such as sulfuric and hydrochloric, the alloys generally have less corrosion resistance than commercially pure titanium itself. One •xception—an alloy containing about 3 % alu minum and 2.5% vanadium—has about the same degree of corrosion resistance as the unalloyed metal.
Methionine Indicated for Schizophrenia Treatment
Russian researchers have made a prelim inary study which indicates that the sulfur amino acid, methionine, has a therapeutic effect in the treatment of schizophrenics. The treatment seems to give best results in the early stages of the illness. The study was made with 20 patients, eight of whom had been ill for only a short time, with the disease in an acute form. The others had been afflicted for a long period. Methionine treatment was beneficial and helped normalize conditional and absolute reflex activity. In some cases the return of normal vascular reflexes preceded clinical im provements. Blood studies showed sharp changes in the index of thymol reaction and glutamine content of the serum after methio nine treatment. The researchers analyzed the urine of the patients and confirmed improved nitrogen metabolism when methionine was administered. It was noticed that patients become more communicative after treatment. Their ap petite and sleep improved, along with their ability to take care of themselves. Psychopathological symptoms leveled off.
All seven alloys are reported to be com pletely resistant to solutions of ferric chloride, sodium chloride and sodium hydroxide and, with very few exceptions, to formic acid— under test conditions. Test results in alumi num chloride solutions were very erratic. However, they do indicate that under some conditions, these solutions can attack both titanium and its alloys very severely. In oxalic acid, all alloys corrode excessively. The program revealed that polished sur faces are more corrosion r e s i s t a n t than pickled-finish surfaces, and that a high dis solved oxygen content in acid solutions slows corrosive action on both the metal and its alloys. The alloys tested, and their chemical analyses, are shown in table 2. They were immersed for 336 hours in the following corrodents at 95°F. and/or 190°F. : 1, 3 and 5 % hydrochloric acid, 5 % sulfuric acid, 5% oxalic acid, 25% formic acid, 25% aluminum chloride, 25% ferric chloride, satu rated sodium chloride and 25% sodium hy droxide. Studies were made without agitation of the cor rosive solution, with air agita-
