INDUSTRIAL NEWS Synthetic p-Cymene
D e e p - W e l l Turbine Pumps
CRODUCTIOX of synthetic p-oymene (structurally p-methylisopro?>\'l benzene) from liquid terpenes is announced by t h e Hercules Powder Co., Wilmington, Del. A hew unit for the production of the material is nearing completion at Che Brunswick Ga., naval stores plant of t h e company. An important use of p-cymene has been as an intermediate in the manufacture of phenols, carvacrol, thymol, and the cyclic alcohol, menthol. The essential oil industry consumes substantial quantities of carvacrol in the m a - a f a c ture of odorants used in soaps.
Jr KOVIDING the main source of water supply for the §63,000,000 Basic Magnesium reduction plant near Boulder City, Xev., the Peerless Pump Division of t h e Food Machinery Corp., San Jose, Calif., reports the novel design of 6 high-capacity deep-well turbine pumps. Each of these pumps, mounted on steel piers extending 200 feet out into Lake Mead, is capable of delivering 3,800 gallons of water per minute, or a combined potential capacity of 32,000,000 gallons daily. Basic Magnesium, Inc., plans to have the Boulder D a m reduction plant deliver 112,000,000 pounds of metallic magnesium a year. The plan is to mine the ore at Gabbs and Mead, Nev., and truck it about 200 miles to the reduction plant. T h e plant needs 196,000 kilowatts of cheap power and 9,000,000 gallons of water daily. T h e power is available only at the Boulder D a m Power House and the only water source in the whole dry area is Lake Mead, formed by the trapped waters of the Colorado River. T h e selection of these pumps follows t h e installation of 30 giant Peerless HydroFoil propeller-type pumps by the D o w Chemical Co. in the magnesium plant at Houston, Tex. These huge pumps individually deliver up to 100,000 gallons per minute against heads of up to 6 0 feet and are being used in extracting magnesium from sea water. This was the process that earned D o w the 1941 Chemical Award for the outstanding achievement of the year.
Portable Water Purifier
V i b r e x Vibrating Screens
A PORTABLE, automatic unit that produces pure, clear, colorless, tasteless, odorless water without the use of chlorine or other chemicals has been developed by the Technicraft Engineering Co., 5610 South Soto St., Los Angeles, Calif. T h e unit, known as the Sterozone Model B , has a capacity in excess of 1,200 gallons per hour and can be installed on any tank or water storage container. For field use a 250gallon canvas bag is used. Power is supplied from 110-volt, 50- to 60-cycle outlet or by a portable gasoline-electric generator. Operation is entirely electrical. N o chlorine or other chemicals now restricted for military requirements are needed. Strip W e l d e r A LOW-COST installation for welding t o gether ends of strips has recently been developed by the Progressive Welder Co., East Outer Drive, Detroit, Mich. It consists of two air-operated series connected guns for spot welding, a notched bar to locate welds, and a control handle to move the gun along, the entire assembly being supported from an I-beam section above which the welding transformer is located.

T h e new screen has a number of features designed to save power, lubricant, screen cloth, and general maintenance costs. Oil-lubricated bearings are supersealed by means of double-action flingers and completely welded splash and dust guards. Inclination of screen, amplitude of vibration, and operating speed m a y all be varied in order to obtain maximum flexibility of application.

and equipment. Already in use on certain government properties, the new paint meets tentative Navy specifications for infrared reflecting paints for use on fuel storage tanks, buildings, and certain types of equipment where dark colors as well as heat-reflecting qualities are required. It is offered commercially under the trade name "Infray" and is being manufactured in green, tan, black, and four intermediate shades.
