Acid-proof masonry can be ready for use within 24 to 36 hours after the last brick is laid, with U.S. Stoneware's "Vitric-10" —the remarkable quick-setting, chemical-hardening cement. "Vi tr ic -10" is resistant to a l l mineral acids, salts, solvents and hydrocarbons (hot or cold ), with the one exception of hydrofluoric acid. "Vitric-10" possesses strong bonding and adhesive properties; is highly resistant to abrasion; i s unaffected by abrupt temperature changes; and is simple to handle.
Acid-proof masonry is built entirely from non-critical materials. In addition to its instant availability, acid-proof masonry offers other very definite advantages fo« chemical plant construction: (1 ) Its initial cost is low; (2 ) properly installed, the maintenance cost is practically nil; (3 ) solution contamination is non-existent; (4 ) acid-proof masonry operates perfectly
at high temperatures or under abrupt temperature changes .
OTHER U. S. STONEWARE CEMENTS In addition to "Vitric-iO", U.S. Stoneware manufactures other highly specialized cements, including: "Pre-MixtM— requires only the addition
o f water. "Portite**— sulphur· base heat-and-pour
type cement. **Vitric*' Fire-proof cement — for acid
cond i t ions cont inuous ly above 5 0 0 degrees F.
"Duralon"—a new synthetic resin cement, completely non-porous with high compressive and tensile strength.
With U.S. Stoneware's "USSCO" acid-brick and U.S. Stoneware's wide range o f acid-proof cements, suitable combinations can be found to work satisfactorily under the most severe operating conditions.

FOR THE PROCESS INDUSTRIES
η the cause of victory few things are more vital than conservation of the nation's dwindling rubber supplies. But fortunately there are hundreds of thousands of tons of scrap rubber available. Fortunately, too, there is no shortage of Barrett Car-bonex* S. When used in reclaim rubber stocks this improved coal-tar compounding material displays a number of significant properties. Extender—up to 15% of the rubber
hydrocarbon. Reinforcing Softener—A highly
practical control of toughness. Rapid Extrusion—Minimizes swell
ing, sagging and flattening. Improved Tear Resistance—An im
portant factor to increase wear. Promotes Better Processing—Calen
dering and extruding properties greatly improved.
Excellent Aging Qualities—A final great help in conservation.
The staff of the Barrett Research Laboratories will be glad to cooperate with you in using Carbonex S and other Barrett rubber compounding materials to meet your requirements. Wire or write today for full information.

Experiments Made in Eucalyptus O i l Production
T H E largest eucalyptus troc plantations in Brazil are found in the State of Sâo Paulo, according to a recent survey, and this state is also the principal center of eucalyptus oil production. Started in 1937, the industry has not gone beyond the cxi>crimental stage. Of the 100,000,000 eucaipytus trees in Sâo Paulo, only 1,000,000 are of a type suitable for distillation of the oil.
Several Brazilian companies have produced oil experiment ally but the results have not come up to the standard of oils imported from Australia. Unfortunately for the essential oil industry, the tall eucalyptus tree is valued chiefly in Brazil for its use :is a fuel and in construction. Usually leaves from felled trees are removed for distillation with little regard for the age oi the tree, selection and maturity of the leaves, time of year, and weather conditions. The resultant oils, therefore, lack uniformity.
Potash Produced from Alunite Deposits
T I I E Commonwealth Supply and Development Minister recently announced that the government of Western Australia will produce potash from the alunite deposits in Lake Campion, according to a report received by the Department of Commerce. It is expected that Australia will eventually supply its total requirements from this source; production will begin with 5,000 tons a year.
Sales of Industrial Chemicals Decrease
W H O I «ESAUSIIS* sales of industrial chemicals of 20 establishments decreased 10 per cent this August, as compared with August a year ago, according to a report of the Bureau of Census. Sales decreased 7 per cent over those made in July; total August sales were S 1,477,000.
Sales of chemicals for the first eight months of this year were reported at $10,216,000. Inventories at the end of August, as reported by 15 establishments, were valued at $916,000, 35 per cent more than those of the previous August. Stock sales ratio for August was 7G; for July, 72 ; fur August, 1941,49.
Sweden Reveals Insecticide Shortage
JKECENT reports from Sweden to our Government indicate an increasing shortage of insecticides. There are still substantial stocks of arsenic powder, but nicotine preparations cover only two thirds of the requirements. Supplies of copper sulfate for the treatment of potatoes against plant mold are sufficient for only 10 per cent of the potato acreage.
1 HE annual consumption of phenol in Mexico amounts to approximately 10,000 kg., it is stated in an industrial report to the Department of Commerce. The United States, and formerly Germany and the Netherlands, have been the chief suppliers.
Venezuela Develops N e w Asbestos Deposit
A PROMISING asbestos deposit has been found near Tinaquillo in the State of Cojedes, Venezuela, and is being developed by Cia. Anon Minas de Amianto de Tinaquillo of Caracas, Venezuela. Most of the asbestos is in irregular cross-fiber veins similar to those in Quebec, Canada.
A mill capable of handling 6,000 tons of asbestos fiber a year is now under construction and is scheduled to be put into operation by the end of 1942.
Germany Studies Masnesite Industry
G E R M A N controlling interests are studying methods of bolstering Austria's mag-nesite industry, according to a report to the Department of Commerce. Within the past year a research group has been looking into the production and treatment of magnesium metal, and a company has been organized to investigate the use of magnesite refractories.
F I V E known deposits of alunite in Australia have been reported by investigators appointed by the South Australian Chemical Institute to study the state's alunite possibilities, says an unofficial report to the government. One of the deposits merits particular attention because of its location close to Port Pirie, where adequate shipping and transport facilities are available.

Tungsten Production in Americas Increased C H I E F producers of tungsten are Bolivia and Argentina, both of which have signed agreements for sale of their exportable tungsten to the United States. Argentina is expected to increase her tungsten production to about 3,000 tons a year, according to a release from the Office of the Coordinator of Inter-American Affairs. Some tungsten is produced in Peru, Mexico, Brazil, and Chile.
Algin Used in Waterproofing Agents
T H E Industrial Research Council in Eire has been experimenting with the utilization of algin in making waterproofing agents and plastic materials. A product was prepared which proved upon testing to be a satisfactory substitute for sago flour in the sizing of twine. The possibilities of this material as a substitute for starch are also being investigated.
Syrian Alcohol Production Decreases
ALCOHOL was formerly manufactured in Syria from molasses imported from Czecho-Slovakia, and the cutting off of imports from that country obliged manufacturers to use seeds and grains obtainable locally. The higher cost of these materials resulted in a considerable increase in the price of alcohol, which rose to about $2.75 per gallon at the end « ' last year. This caused a decreased demand, and the output for 1941 dropped to 130 tons, about 50 per cent of the normal annual production.
New Franco-German Dyestuffs Company Created CREATION of a new Franco-German dye-stuffs company has been approved by the Vichy government, according to an unofficial report.

ALTHOUGH the extension of the war and the shortage of tonnage destroyed many former markets, unofficial reports received from Chile by the Department of Commerce indicate the nitrate industry maintained a high level of activity during the past year. For the first time since 1933 stocks on hand were low enough to require extra production to build them up as a reserve against possible heavy sales.
HAITIAN· trade statistics, obtained through a Department of Commerce report, show 18,673 kg. of chemical and pharmaceutical products imported during May, valued at $6,489. For the 8 months October 1941 to May 1942, imports were 471,758 kg., with a value of $133,074.

Foundation Appointments Γ Ϊ ^ Η Ε uppointments to fellowships under
the sixth annual series of fellowship awards of trie Lalor Foundation, which covers the academic year 1942-43, are:
A. Calvin Bratton from the University of Texas to work with Ε. Κ. Marshall at Johns Hopkins University Medical School.
Edward H. Frieden from the University of California to work with Roger J. Williams at the University of Texas.
Francis J. Reithel from the University of Oregon to work with Edward A. Doisy at St. Louis University School of Medicine.
James R. Weisiger from Johns Hopkins University to work with A. Baird Hastings at Harvard University Medical School.
The work of these men is in fields closely associated with problems related to the war.
Owing to war conditions, appointments to the five remaining fellowships originally scheduled for the 1942-43 series have been postponed.
The present plan of the foundation is to discontinue its regular program of fellowship awards until the demobilization of scientific personnel a t the end of the war. Thus the usual fellowship awards will go into a reserve t o form an accumulation for post-war assignment. To date 15 such awards are scheduled to be made available at that time for post-doctorate research in chemistry. T h e standard annual stipend of a Lalor Foundation award is $2,000.

Isopropyl Ether Explosion
Ι τ is well known that isopropyl ether forms jieroxides very readily, and that
these peroxides may cause an explosion if the ether is distilled or an ether extract is taken to dryness on a hot plate. It seems less well known that an old sample of isopropyl ether may detonate if jarred.
A ")-gallon can, about one quarter full of isopropyl ether, was placed on the floor under a shelf in the stockroom several years ago and apparently forgotten. One morning a janitor decided to move it when he swept. As soon as he lifted the can, it exploded. The detonation occurred in the liquid phase, not in the vapor. The upper part of the can was uninjured. The tin in contact with the liquid showed no evidence of great force outward, but the metal was stretched severe!}'. The tin was pulled thin, and many small tears appeared, a few millimeters in length. The two largest tears were 4 and 14 cm. long.
Fortunately, the ether did not catch fire, and the janitor was uninjured.

Second Annual Science Talent Search
r I "WEXTY-FIVE thousand high school principals and teachers have been in
vited to take part in a nation-wide search among the country's 1,G50,000 high school seniors for the 40 most taiented young scientists of that age in America.
The 40 are to be singled out for special honors and opportunities including attendance at a five-day Science Talent Institute at Washington next February, and up to §14,000 in scholarships.
The invitation was sent by Science Clubs of America, an organization fostered by Science Service. The Science Talent Search, second to be held, is made financially possible by the Westinghouse Elec
tric «fc Manufacturing Co., which will award WoMinghouse Science Scholarships to at le:i>t 10, and possibly 40, of the young scientists of the future.
During the institute the contestants will compete in final examinations for the scholarships, which will result in the awarding of eight four-year Westinghouse Science Scholarships of $40O eacli and two four-year Westinghouse Science Grand Scholarships of $2,400 each, worth $60O per year. One boy and one girl will be selected as winners of the Grand Scholarships. Alternates will b e named. Additional $100 scholarships will be awarded at the discretion of the judges.
The Science Talent Search is administered by a committee of four: Harlow Shîipley, director, Harvard Observatory»
a n d chairman of Science Service's execut ive committee; Watson Davis, director, Science Service; G. Edward Pendray, assistant to president, Wrestinghouse Electric & Manufacturing Co.; and Ε. Β. Roberts, assistant to vice president of Westinghouse.

Conservation of Critical Materials APPLICATION to the war production ef-
" ^ fort of all the skill and management "'know how" acquired by General Motors through many years of manufacturing experience is resulting in the conservation of thousands of tons of critical materials, in important savings in man hours (thus releasing men and machines for further -vital work), in sharply reduced costs, in the organization of new methods in maintenance and service, and u substantial contributions to an advancing military technology, Alfred P. Sloan, Jr., chairman o f the corporation, states.
M?\ tl-oan says that production rates have beci. accelerated, engines have been increased in aorsepower, guns have been simplified and given longer life, and improvements have been made in tank construction, in airplane propeller design, and in the manufacture of shells. New devices have been developed, new characteristics built into old devices. Meanwhile, a sound basis has been established for continued advance in war production techniques.

Eliminate MANIFOLDING
Multiclone's exclusive vane design permits any number of tubes to be installed with one inlet header and one outlet header simplifying construction and eliminating the complications of manifolding. Less material is needed. Less floor area and less headroom are required. Because the gas travels over a smaller surface there is less surface subject to wear and because of the vane type of construction, should wear occur, it can affect only parts that are easily and readily replaceable without dismantling the entire unit. In the Multiclone, the simplified header construction together with the enclosure of the tubes by the hopper greatly reduces heat radiation. This facilitates temperature control and where condensation might occur reduces insulation requirements to a minimum. The Multi-clone design makes possible its installation in existing structures in what would otherwise be wasM- spare J»:.«J m t>laces where manifold· . . v o Id be impossiL,/·· The smgle manhole ι trough which all tube* can be reached sim^ ! ;f es inspection. Thus the elimination of mai». '-"·»»» simplifies installation, saves space, decreases v u u n g surface, reduces heat radiation and gives better temperature control.

Portraying the extra contribution that H-B INSTRUMENT COMPANY makes in the temperature field is the fact that its Certified Standard Thermometers are constantly checked and rechecked against the International Temperatures Scale with a Platinum Resistance Thermometer. This insures a continuing guarantee of accuracy for critical H-B thermometers and thermostats.
The use of the Platinum Resistance Thermometer and Mueller Bridge Circuit, through application of the Callendar Formula, makes possible the manufacturing of thermometers in a new temperature range. In tliis way, a new mercury or mercury-alloy thermometer is developed. It is then checked against the Platinum Resistance Thermometer to determine the accuracy of this first instrument and thus construct a dependable standard for the new line. With this instrument reading temperatures to .001° H-B INSTRUMENT COMPANY can make standards enabling them to guarantee new or special thermometers accurate to .01°.
This is why today's vital Ordinance plants turn first t o H-B INSTRUMENT COMPANY for special temperature instruments for TNT, Toluene, and other explosives and for radio transmission thermometers and thermostats.
Let H-B Instruments solve your unusual Thermometer problems.

Great Jumping JEEPS!
MEET THE ARMY'S MECHANICAL MULE . . .
The Jeep—our Army's mechanical mule, has achieved a reputation of out-climbing, out-pulling and out-maneuvering anything of its weight ever put on four wheels . O n every war front in the world, the Jeep i s now the pride and joy of Brass Hats and Buck Privates alike.
But remember the men who build the Jeeps—those w h o train to operate and foll ow them—and the millions of others -who are engaged in our war effort. For all, there had to be an abundance of water. It w a s the Layne Organization, who in the majority of cases , drilled the wells and built the systems that provide water b y the millions of gallons. To a well water system, the name Layne is as famed as i s the name Jeep to a four wheel vehicle.
Layne's reputation like that of the Jeep has been w o n on the f i e l d of a c t i o n . Throughout the entire Nation. Layne wells and pumps are doing a magnificent job —providing water for ordnance plants, munition factories, t r a i n i n g camps, air fields, ship yards and all kinds of war m a t e r i a l producers.

Lead Substituted for Critical Materials
X ^ V B R since the Bureau of Industrial ^ Conservation of the War Production
Board several months ago placed lead in the group of materials available in sufficient quantity t o be used as a substitute for more critical materials, the WPB, Army and N a v y officials, as well as industry, have been searching diligently for uses of lead that would relieve more critical materials. Lead is the only common metal classified in the least critical group. Already considerable progress has been made.
The use of lead to save critical materials falls naturally into two categories. First, there are many purposes for which lead is normally used t o a greater or lesser extent in competition with other materials now critical, for example, in plumbing and for sheet metal work on buildings. Lead-base bearing alloys are rapidly supplanting tin-base alloys in ship construction, Diesel engines, and many other places. Lead-base die-casting alloys are supplanting zinc-base alloys for many purposes when high strength is not important but where good casting qualities are. The lead-base alloys, in addition, are generally superior for corrosion resistance.
Lead pipe and tank linings are taking the place of rubber in many industrial operations. Lead gaskets are, in many instances, proving superior to rubber gaskets used for a multitude of purposes. Lead collapsible tubes have largely displaced those made of tin and aluminum, and lead foil laminated wrappings are finding wide use. Lead coatings are saving much zinc, tin, cadmium, and nickel, formerly used to protect iron and steel products.
In the paint field, considerable savings of critical materials are also possible through wider use of lead pigments.
Lead alloy name plates, hard lead drum trap covers and rings, and water closet floor flanges take the place of brass. Lead alloy couplings are being employed in place of copper and bronze on certain types of cement-asbestos pipe.

Soap Dispersions Speed Production
(~\F DEFINITE importance in large-scale ^ ^ industrial and war work is a revolutionary type of paint recently developed. It consists essentially of a suspension of synthetic resins and pigment in soapy water. This paint is nonflammable, quick drying, and eliminates noxious vapors. Resin emulsion paints are being used to camouflage gun emplacements, munitions depots, and large war plants. The dull finish for many Army vehicles is supplied by emulsion paints.
Soap is applied to other war problems in a modern method for the preparation of building blocks from clayey soil and a bitumen emulsion (U. S. Patent 2,275,087). Large numbers of field structures must be put up quickly in modern warfare, and any method which eases the strain on transportation facilities is of obvious value. In this new process only a portable mixer-extruoer and a small amount of soap bitumen emulsion need be transported. The main component of the blocks can usually be obtained from the ground around the building area. Another advantage is that the blocks dry within 24 hours, so that fast construction with little storage space is possible.
Asphaltic emulsions will also help alleviate the rubber tire shortage when the new "wrap-around" substitutes are ready for sale. These consist essentially of a heavy ruglike cloth coated with an asphalt emulsion, which can literally be wrapped around the worn-out tires. While the mileage obtainable from these coatings is not great in comparison with rubber treads i t is reported that their use is justified by their low cost.
Soap as a Road Builder r Ι ΛΗΕ value of soap as a road-building
material was tested recently in experiments made by the Michigan State Highway Department. Soap was mixed with fine sand and used in an effort to resist surface scaling resulting from the use of calcium chloride and sodium chloride spread to remove ice in winter.
Soap a Black-Out A i d Γ Ν BRITAIN where enemy bombers can
be guided to their objectives by light-colored roads visible from the air, bituminous emulsions made with soap are being considered t o black-out these conspicuous surfaces. B y painting a dilute bitumen emulsion on the roadway and dusting with pulverized coal, a cheap and durable blackening effect is obtained (British Patent 534,889).

By the simple expediency of embodying α BOWEN spray-dryer within a furnace, so that the walls of the chamber are radiant, the rate of evaporation is speeded tremendously. A drop of water under such conditions becomes similar to a "Black Body** because the radiant heat is all absorbed, and none is given out. The products o f combustion enter the drying chamber in the usual manner and perform their drying operation by conduction and convection, but in addition, the radiant walls of the drying chamber adds heat to the particle of water with the speed of light. This heat penetrates to the center o f every particle, vastly increasing its enternal energy and rate of evaporation. Inquiries are invited.

Live and Learn
A FTER thirty-odd years of experience in • ^ the chemistry and technology of foods I recently have had two experiences which suggest that a specialist may be surrounded by everyday facts connected with his speciality but concerning which he is utterly ignorant.
1. I have long deemed it expedient to order poached eggs at restaurants of questionable standing in view of the fact that only a first-class egg will poach successfully. A short time ago at a restaurant of reasonably high grade I was served a "sour" poached egg and on complaining was informed that they always put vinegar in the water in which eggs were to be poached and that an apology (and another egg) were due me because this time the chef had overdone the acidification. I wonder whether this custom is due to an accidental discovery or to expert professional advice.
2. On the diner recently I was served ice cream, the taste of which brought me up standing almost literally. There was an acrid pungency to it utterly foreign to my experience with this favorite delicacy. Instantly I was flooded with thoughts of toxic bacterial activity. I called the steward and reported, expecting him to register at least mild excitement. Not at all. He explained quite casually that the strange taste was that of the dry-ice in which the ice cream had been packed and that my experience was a common one. I tasted again gingerly and was convinced it was the flavor of the useful, necessary-carbon dioxide and none other, obviously highly soluble in ice cream mix at freezing temperatures.

T. F. Bradley, a research group leader at the laboratory, is leader of the squad there and is instructor of the city squad, as well as gas identification expert for the Auxiliary Police.
The laboratory squad numbers ten, all trained in how to combat the effects of gas, and equipped with masks and gasproof clothing.
Cellophane Protecting Army Rations
/ ^ E L L O P H A N E is among the materials ^ tested and approved by the U. S. Army Quartermaster Corps for the protection of emergency rations, and tons of cellophane have gone into this use. The packaging must keep foods satisfactorily for a year, protecting them from snow and subzero temperature as well as the sun, heat, and high atmospheric humidity of the tropics. The Κ ration, formerly called "parachute ration", is now intended for general use in training maneuvers and in many fighting areas. It consists of three meals, weighing slightly more than 2 pounds and providing more than 3,700 calories of energy.
