The success of the e\periment was such that 80.000 sq. ft. of partitions made from porcelain enameled aluminum have been in stalled on the carrier L SS Saratoga and the LSS Forrestal is also being fitted out with the material, after her launching several months ago. Light ness. ease of working and no main tenance were important considera tions. of course, but so was the supe rior resistance to fire hazard and the friability of the vitreous coating. On one hand paint is eliminated, on the other the enameled aluminum has a higher melting point than the un coated stock, whose low melting point has been an objection to such use of aluminum by the Navy. Concerning friability, under severe impact or bending the coating breaks up into powder or small bits, avoiding schrapnel-like large pieces. The Navy is also sponsoring experiments in color harmony as an effective morale booster, particularly in submarines. Porcelain enameled aluminum figures prominently in this investigation. The variety of uses to which por celain enameled aluminum has been put may be further indicated by its use for traffic signs, colored storm sash and architectural tile. The bright red strips that signify to the motorist a Texaco service station are in many instances of enameled aluminum.

KAWNEER CO. just about to come onto the scene are products made from aluminum cast ings that have been porcelain enam eled--for instance, a line of cast alu minum cooking utensils whose out sides are pastel shaded with porcelain enamel. Lead, in the form of oxides and silicate, has long been used in the ceramic field. It imparts brilliance and clarity to glassware, it provides color in dinnerware and in the ce ramic labels on manv bottles, and it is a component of the enamel on power resistors. In the enamel for aluminum lead is prominent because of the lowtemperature requirement in working with aluminum. Enamel coatings are made from the product of pouring molten glass compounds into water, the glass shattering into fine particles which are called frit. The frit for the enameling of aluminum contains 30 to 50 percent lead. It fuses at a little above 950 deg. F. while the melting point of aluminum is 935 to 1215 deg. F. A typical porcelain enameling of aluminum operation might be sum marized so: The frit is ground in a ball mill in a water suspension. Mean while. the aluminum stock is pre treated. prefired and cooled. The suspension is then applied in a thin, smooth ground coat, which is gener ally unpigmented. by dipping, slush ing or spraying. The stock is dried at low temperature and fired. Finally, after the ground coated stock is cooled to room temperature the cover coat i sometimes more than one ) is applied bv spraying and is fired.

It L J A 2 6055 Lead Lining For Sulphur Dioxide Recovery Units SULPHURIC acid is an invaluable commodity in practically all indus tries. but often it poses problems. It is. for instance, not only highly cor rosive to practically all materials, with the notable exception of lead, but in even small amounts it can become a serious nuisance as an air or stream pollutant. One specialized form of sulphuric acid production, the recovery of waste sulphur dioxide gas from sulphuric acid plants and its conversion to acid, has become an increasingly important field--largely because of the growing emphasis on air pollution prevention. In this development the Olin Mathieson Chemical Corp. has recently an nounced the perfection of a two-stage exit gas scrubbing process which has permitted increases as high as 20 per cent in sulphuric acid plant operating rate. The process was developed originallv bv the Consolidated Mining and Smelting Co. of Canada. Ltd.. Towering into the on is the scrubbe' touer of the OUn Mathieson Chemical Corp.'s S0-2 recovery plant at Pasadena. Tex. The scrubber sump and the strip, per adjoining the tower are lead lined. Inert gas to atmosphere and is known as the Cominco SO2 Recovery Process. Even at the most efficient rates of operation, contact sulfuric acid plants normally sustain some economic loss in the sulphur which is discharged into the air as exit gases in the form of sulphur dioxide and suiphur trioxidc. The two-stage scrubber returns this sulphur to the production unit. Thus, not only are economic losses avoided but in areas where discharge of sul phur dioxide from the stacks could create an air pollution problem the process provides effective abatement while at the same time disposing of the recovered sulphur in such a man ner as to avoid the equally unwelcome nuisance of water pollution. The first system utilizing the pro cess in the United States was put into operation more than a year ago bv Olin Mathieson at its Pasadena. Texas plant. There the two-stage scrubber using ammonium sulphite-bisulphite scrubbing solution returns sulphur dioxide to the production unit and converts part of the acidic values in the exit gases to ammonium sulphate. The unit relies for corrosion pro tection of the steel and concrete con- Olin Mathieson's tun^mec exit gas scrubbing process lor the rrcoters at sulphur dioxide and rontcrsiun '>> tirin' has increased suiphunr ncid plant operating rote ns /ugh as 20 percent, unite ai oidmg air or stnuim pol lution.

The stripper is a steel vessel lined with 10-lb. chemical lead. In both cases the lead is strapped to the vessel: in the scrubber sump directly to the con crete; in the stripper to the steel. The steel straps used are. in the customarv fashion, covered with strips of lead burned to the lining to present a con tinuous lead surface. The recovery system has been in operation since August. 1953. Inspection after one year's service found the lead to be in excellent condition. How lead is effectively and effici ently being used to handle and control sulphuric acid in all concentrations up to 96 percent has been covered in many previous issues of Le a d as well as in Lead Chemical Construction Bulletins, available from the Lead In dustries .Association, which deal spe cifically with the characteristics of lead in use with sulphuric acid. Red Lead Protects Twin-Lift Bridge SOME 14.000 tons of steel are go ing into the New York Central Railroad's new 318.000.000 twin-lift bridge which spans the Harlem River in New York City. In keeping with the railroad's established practice, a red lead primer was called upon to do the job of first line protection of the steel against the ravages of cor rosion. The new vertical lift structure -- actually two almost identical bridges side by side, each carrying two tracks--is being constructed immedi ately to the west of, and then will re place. the present swing bridge be tween Manhattan and the Bronx. The first of the spans is already in opera tion. ^Vhen the bridge is completed in 1956 it will carry all of the heavy train movements to and from Grand Central Terminal. The new structure will be the fifth -- and finest -- of its line. Wooden bridges were erected originally, in 1841 (actually, a conversion of a Soon lo replace altogether the older bridge at right is the Sew York Central Railroad's twin-span lift bridge over the Harlem River in Sew York City. Like us predecessor, the new bridge depends upon red lead for first line protection against corrosion. highway bridge built in 1790) and in 1856. and the third structure, a double-track iron span, in 1871. The present steel bridge, constructed in 1897. has been modernized many times to care for the increasing size and weight of trains. The new bridge, built for the future, will be able to carry the heaviest foreseeable trains, and construction is being coordinated w 1 th various highway improvements in that immediate area. Raised, the new span will clear masts up to 135 ft. high. and will leave an open chan nel 225 ft. wide, compared with two present 100-foot channels. Overall, VOLUME 2 OF STEEL STRUCTURES PAINTING MANUAL AVAILABLE Now made possible by the publication of Volume 2 of the Steel Struc tures Painting Manual is thei. specification of the painting of a steel structure in the same easy, precise method as the steel itself is specified-- by reference to a specification number. Entitled "Systems and Speci fications" the new volume contains specific recommendations for paint ing a wide variety of steel -structures and surfaces in diversified exposures. The recommendations cover surface preparation, pretreatment, paint application, paints and paint systems. Very prominent in the recommen dations are red lead primers. Copies of the 292-page "Systems and Specifications" may be had at $6.00 each, postpaid, from the Steel Structures Painting Council, 4400 Fifth Ave,, Pittsburgh 13, Pa. Also available in separate volumes are the 20 SSPC Paint Specifications and the 9 SSPC Paint System Specifications at a price of $1.50 for each booklet. including approaches, the bridge will be 1.780 ft. long. The primer used on the Harlem River bridge wasapplied over a sur face which had been prepared by wire brushing.
