George C. Krug, company president, "and we will save $5 a ton by using barges/* Asphalt presently supplied to the Knoxville area comes from Louisi­ana, Mississippi, Arkansas, and Texas, according to company officials.

"Our plans for the future include ex­pansion into the asphalt roofing busi­ness," says Krug, "and we hope to open a felt saturating unit (heavy cardboard which serves as a base for roofing paper and shingling)/* Krug indicated that Volunteer may eventually have its own felt mill.

Volunteer will distribute the roofing material; later on the plant will blend and store "cold" asphalts for road use, mixtures of asphalt and naphtha in six different grades.

Survey Nuclear Energy From Industrial Viewpoint

A survey of the nuclear energy field for industries has been completed by the University of Michigan. Results have been published and are now be­ing distributed.

The survey seeks to portray "the vast area of opportunity and effort confronting American industry in the rapidly expanding nuclear field/* The study is published as A Peacetime Sur­

vey of Nuclear Energy from an Indus­trial Viewpoint. It is a condensation of information from many unclassified publications, as well as from original investigations.

The survey shows where every in­dustry can find a role in the nuclear power field, be it in the mining and preparation of fuel ores, utilization of power from nuclear reactors, use of radioactive materials produced in the reactors, chemical processing of "used" fuels or the manufacture of instruments to measure ,and control atomic energy. At the same time, the study points out those places where industry can expect to encounter difficulties, such as in the handling and storage of intensely radio­active by-products.

This survey is the first contribution of the university's industry program, launched this past fall to open direct channels of communication between its college of engineering and industry. Under it the college will disseminate nonconfidential information to, and ar­range technical meetings for, industries enrolled for a fee of $5000 a year for three years. At the same time, the university expects to enrich its own educational program through increased contact and cooperation with indus­try's representatives, and through the

undertaking of sponsored research projects.

A second manual—which will treat the welding of new metals and alloys— and preprints of technical papers pro­duced by university faculty members are scheduled to be distributed early this year.

Consolidated Chemical Industries Ships First Aluminum Sulfate

First shipments of aluminum sulfate liquor are being made this month from a new unit at Consolidated Chemical Industries* Houston plant. To supply raw materials for the new aluminum sulfate liquor production, sulfuric acid will come from CCFs plant in Hous­ton, and bauxite will be shipped from its Arkansas mines.

Aluminum sulfate liquor is used largely in manufacture of paper, as a fiber binder, and as a coagulate in treatment of surface water for indus­try and for sanitary water supplies. Shipments are made either in rubber-lined tank cars or in tank trucks for overnight delivery to water-treating plants. CCI has two similar plants at Springhill and Bastrop, La .

In April C C I expects to open still another new unit at its Houston plant: a sludge acid plant. The regeneration unit will produce new sulfuric acid from spent sulfuric.

Hercules Adds Resin Facilities a t Holyoke

Additional manufacturing facilities for the production of wet-strength res­ins for paper will be built at Hercules* Holyoke, Mass., plant. The new pro­duction unit is expected to be in opera­tion in April or May. The wet-strength resins will be available in tank car, tank truck, and d rum quantities from the new unit.

The Holyoke plant also produces wax emulsions, resin emulsions, and de-foamers for the paper industry and is a distribution point for dry rosin size and paste rosin size.

National Starch Contracts For PVA Adhesives Plant

Blaw-Knox's chemical plants division has been awarded a contract by Na­tional Starch Products for engineering, procurement, and construction of a polyvinyl acetate polymer plant to pro­duce vinyl adhesives. Erection of the plant on a recently acquired 120 acre site at Meredosia, 111., will start early this year; completion is scheduled dur­ing the summer.

Since the adhesives are tailored to suit individual customers' require­ments, maximum flexibility of opera­tion has been incorporated in the plant design. Process facilities, warehouse, tank farm, utilities, and auxiliaries will be installed with provisions for pos­sible future expansion.

Products from the new facility will be shipped by truck or rail to comple­ment production from a similar in­stallation at Plainfield, N . J.

Consolidated Wi l l Make Phillips Control Equipment

An agreement has been reached by Consolidated Engineering and Phillips Petroleum. Under it Consolidated will make and market continuous plant analysis and control instruments devel­oped by Phillips.

Consolidated calls this one of the most significant milestones in its his­tory as designer and manufacturer of electronic data processing and control instrumentation.

Instruments proposed for immediate marketing include infrared gas analyz­ers, differential refractometers, ultra­violet analyzers, and oxygen analyzers. Housed in explosion-proof enclosures, all of the devices are capable of con­tinuous and automatic control of such operations as fractionation, blending, and chemical synthesis, to improve product quality and increase yields.

AFL Engineers Launch Apprenticeship Program

In a move to alleviate the nation's shortage of trained draftsmen and tech­nicians for industry and defense, the American Federation of Technical En­gineers, AFL, has launched a nation­wide apprenticeship program. This is being done in cooperation with the De­partment of Labor.

Members of the federation's locals-draftsmen and technicians employed

by local industry—will participate in the program, establishing local appren­ticeship committees. These will work with government representatives to es­tablish apprenticeship schools.

Object of the program: training of subprofessional employees to release more highly skilled professional engi­neers for more technical work.

21,482 Feet Is Far Enough Drilling has stopped at 21,482 feet

on the deepest dry-hole ever drilled. Down the hole: $2,225,000. After more than 38 months, probing previ­ously unexplored formations below the Paloma oil field about 25 miles from Bakersfield, Calif., has ceased. Ohio Oil bears the brunt of the cost, about $1.9 million. The rest will b e split by Texaco, Western Gulf, Lloyd Corp., Hancock Oil, General Petro­leum, and Pacific Western Oil.

"If we did not find oil, at least w e proved that modern rotary equip­ment in the hands of skilled crews is capable of drilling to depths of 21,000 feet plus," J. C. Donnell II, Ohio Oil's president, comments.

Solar's novel c'kmk prevents pressure

thrust in 11/2 mile steam line

}?

THIS HINGED EXPANSION LOOP was designed by Solar engineers to solve an unusual problem at Lion Oil Company's Barton Plant, in Lul ing , La. The steam line shown above runs more than VA miles, operates at 200 psi and a temperature of 560 Ε The problem was to stop pressure thrust and accommodate a large amount of pipe expansion.

Hinged expansion joint

The expansion loop employs four Sola-Flex hinged bellows joints, each requiring only 4 degrees of angulation. Yet three of these loops permit twenty-seven feet of expansion, thus accommo­dating the expansion of the entire 1% mile steam line!

E x p e r i e n c e d Solar e n g i n e e r i n g teams are always ready to help solve your high and low pressure piping prob­lems. And Solar can follow through — with standard or custom-built expansion joints and convoluted couplings for all your piping needs. Send for Sola-Flex catalogs today.
