NITRIC OXIDE W e are now manufacturing Nitric Oxide in our East Rutherford, N. J., plant. This gas was added to our line at the insistent request of many research laboratories. Our Nitric Oxide has a purity of 98.7% and is available in four different sizes of cylinders at a pressure of 480 pounds per square inch. Ample stocks are carried at both our East Rutherford, N. J., and Joliet, 111., plants.
Pure Organic Chemicals Over 2500 organic chemicals stocked for immediate delivery. Included are all the building blocks needed by the chemist in industry, the research labo ratory or the university. The purity of each Matheson organic chemical is guaranteed by our strict l*V>nratorv controls. p'h f:V~4

CONTAINERS AND TRANSPORTATION Pipeline Pumps Heated Oil to Tankers Gulf Refining Co. has pioneered a new field in low-gravity, highly viscous oil traasportation in the construction of its heated pipeline now carrying oil from South Mississippi fields to its terminal on the iMobile River. The company's 152-mile pipeline is unique in that it marks the first attempt to move such highly viscous oil such a great distance. The heavy oil is gathered from the Heidelberg, Eucutta, Yellow Creek, and Baxterville fields by the Interstate Pipeline Co.'s gathering system and delivered to Gulf at Eucutta. At Eucutta, Gulf has four 10,000-barrel storage tanks to receive this oil. In these tanks the oil is heated and pumped into GulFs line located abopt*20 inches under ground for the trip to the coast. The oil is heated in the storage tanks by steam coils, then flows through the pumps, after which it is warmed again in twin heat ex changers, 20-foot horizontal installations filled with many feet of steam-charged three-quarter inch tubing, and then driven into the 10-inch pipeline under heavy pres sure. The oil then travels 64 miles through the pipe to Lumberton. On the way it is heated again at an intermediary station, where is flows through heat exchangers. At Lumberton it is placed in huge storage tanks and again warmed in a heater coil assembly. From the Lumberton storage tanks the oil is again run through heat ex changers and into the main 14-inch line that runs to Mobile, a distance of 88 miles. Eight heater stations and a combination heater-pumping station aj:e located along this line at 10-mile intervals. At each sta tion the oil is run through heat exchangers to increase temperature from 40° to 50° F. The job of warming the oil on its long journey involves a labyrinth of pipes and equipment and an immense amount of ma chinery and fuel. The heating is done with steam generated by boilers fired with nat ural gas. About 4 million cubic feet of natural gas and thousands of gallons of water daily are required to heat the oil.

Tin conservation methods with sheet metal materials currently available to the manufacturers of metal cans have been virtually exhausted, stated R. R. Hartwell of American Can Co.'s research and tech nical department in a paper presented be fore the 45th annual convention of the Na tional Canners Association in Atlantic City. "While tin conservation studies employing currently available materials are under way, any further substantial savings are dependent on the availability of materials not yet in large scale production, namely, chemically treated steel and differentially coated tin plate. For nonacid foods, CHEMICAL

chemically treated steel plate, a tinless material, offers the greatest possibilities, Hartwell pointed out. For acid fruits and evaporated milk, an entirely new material, differentially coated electrolytic tin plate, carrying a relatively heavy tin coating on the inside of the can and light coating on the outside, will reduce amount of tin re quired for this segment of the industry by 30 to 35%. Production of differentially coated plate in adequate quality and quantity is dependent upon some costly revamping of current tin mill practices in order to produce a product possessing adequate resistance, he stated. "With the material currendy available the can manufacturers are directing their efforts to the extension of the use of the so-called "combination can," that is, a con tainer with a plain, hot clipped tin plate body and enameled electrolytic tin plate ends," Mr. Hartwell stated. This type can perform equally as well as the cans made of heavily coated hot dipped tin plate throughout, and it may be expected that this type will be further exploited. Another means of tin saving mentioned in Mr. HartwelTs paper is that of side seam stripping, which is an application .of an enamel coat to the side seam of the can body after fabrication of the container— an effective way to extend shelf life of con tainers constructed with light-coated elec trolytic tin plate in the body of the can.
Mercury Dispenser Bethlehem Apparatus Co., Inc., is now marketing instrument mercury in an un breakable 5-pound polyethylene bottle with a flexible dispensing tip. The tip delivers the mercury directly to the in struments, such as manometers, polarographs, and thermometers. Transfer con tainers, spillage, and exposure of mercury to impurities in the air are thus elimi nated. The instrument mercury is claimed to be purified of contaminants. C1
Plastic Vials Plastic vials, which consist of poly styrene containers and .polyethylene clo sures, are being manufactured by New York Plastics Corp. They are shatter proof and uniform in dimensions. They are also less breakable, more economical, and about one fourth the weight of similar glass vials. These containers are avail able in crystal clear, opaque, and gemlite colors and can be permanently printed and decorated. Many types of products can be packaged in these vials, such as drugs and pharmaceuticals, cosmetics, and industrial parts. C2 AND
