for NOVEMBER 30, 1929

Tantalum, Molybdenum, Tungsten— Something of the vision of the pioneer, and the romance of discovery, is contained in the booklet “Rare Metals,” published by the Fansteel Products Company, Inc., North Chicago, Illinois. The booklet was particularly designed to acquaint the reader with the rare metals of tantalum, tungsten and molybdenum; to show how they are now being used commercially; and to suggest possible uses in the reader’s own plant or product. “Rare” is only a comparative term, and the metallurgist and chemist, by their painstaking and tireless research work, have placed many of the former “rare” metals into everyday use.

The demand for new metals almost always has exceeded the progress made in making them available for commercial use. Aviation cries for an engine-metal lighter than aluminum, stronger than steel; industries needs a metal that is proofed against “fatigue,” and another against rust; television, just around the corner, demands a new set of metals.

It is the policy of the Fansteel Company to look ahead, to foresee the demands of industry five, ten, twenty-five years from now, and make the necessary efforts to have metals ready when new demands appear. It is also Fansteel’s policy to invite industry to submit its metallurgical problems to Fansteel research men, who will gladly cooperate with any industry in discovering, and developing suitable metals and alloys for current and future needs.

Fansteel’s is a quest for the treasure of new knowledge —for that treasure far greater and far more useful, than all the treasures buried in sand by the buccaneers of old.

Float at Edison Jubilee—

Five hundred thousand people are estimated to have lined the route of march to witness a gigantic parade of illuminated floats, in Pittsburgh, October 23, as a fitting climax to the celebration of Light’s Golden Jubilee, in honor of Thomas A. Edison and his invention of the incandescent lamp. In addition to honoring Mr. Edison, the memory of four of Pittsburgh’s sons were likewise honored; namely, Andrew Carnegie, H. C. Prick, H. J. Heinz, and George W. Westinghouse.

Conspicuous among these floats was that of the Mine Safety Appliances Company, which depicted the use of the Edison Electric Safety Mine Lamp. The M-S-A float was built so as to represent a mine entrance, and just outside of the entrance, was a pit wagon filled with coal, surrounded by four miners wearing the Edison Safety Cap Lamp, his great contribution to mine safety. For many years, the Mine Safety Appliances Company has been exclusive distributor of these lamps for Mr. Edison.

An unusual bit of romance is attached to the development of the Edison lamp. Back in 1911, when the Edison nickel-iron alkaline storage battery had passed the development stage, and was being successfully used, certain executives of the Philadelphia and Reading Coal and Iron Company interviewed Mr. Edison, and told him of their intense interest in electric lamps for underground workmen in order to provide better illumination and safety against the ignition of gas.

This humanitarian appeal interested Edison greatly, and although deeply absorbed in other lines of research work, he found time to devote to the development of the miners’ lamp, and made up a number of lamps operated by miniature storage batteries, which were subsequently approved by the United States Bureau of Mines. Mr. Edison at the time, did not realize that the lamp had any commercial value, but since this great invention, the Mine Safety Appliances Company of Pittsburgh, Pennsylvania, has distributed more than 850,000 Edison Cap Lamps in the United States and Canada.

IMPORTANT DESERT LIBRARY DONATED TO MACKAY SCHOOL

Led in the course of his studies, to the question of the formation of the deserts of the world, Dr. Johannes Walther of Halle, Germany, became, through his knowledge of the arid regions of the earth, the greatest authority on the subject. During the 60 years of his activity, Dr. Walther, originally a paleontologist, exchanged papers with the foremost geologists of the world, and gathered together a library which covers practically all branches of science. It is especially rich in papers on the formations of deserts, and the recent geological periods, as well as many of the older monographs on paleontology, and fossils, that are almost impossible to obtain in any other way except in the older libraries.
This library, composed of between six and seven thousand papers, published in the past 60 years, has been purchased by Clarence H. Mackay, for the Mackay School of Mines. It is now being catalogued and will soon be available for use at the school library, Reno, Nevada.

LARGE INCREASE IN LIGHTING FACILITIES IS RECOMMENDED

The people of the United States can use to advantage, more than five times as much light as they are using at present, electrical engineers stated at a meeting of the New York Section of the American Institute of Electrical Engineers, which was held in New York City recently, at the Westinghouse Lighting Institute, Grand Central Palace.

The amount of electric light being used today is only 17 percent of the minimum recommended level, and but 13 percent of the probable level of greatest economic advantage, were the conclusions of a report on “How Much Light?”, the first ever prepared on the subject, submitted to the meeting by Frank W. Smith, chairman of the lamp committee of the National Electric Light Association, Arthur E. Allen, vice-president Westinghouse Lamp Company, and E. E. Free, consulting engineer. These figures apply only to the indoor lighting of homes, factories, offices,
etc., and take no account of the lighting of streets, highways, etc.

With outdoor lighting included, it is evident that a very large field for expansion, lies before the electric light, and power companies, in the present lighting field alone, without reference to future developments or other fields.

The report analyzed the light needs of the human eye from the standpoints of perceiving objects; doing special work such as typesetting; doing regular productive work in factories; comparisons with daylight, for which the eye was created; and computations from the characteristics of the light perceiving elements in the retina of the eye.

With data secured in these ways, as a basis, the amount of light needed for each human occupation was determined, then the needs for the average family, and finally for all the families in the country.

It was estimated that the present consumption of electricity for lighting purposes was 20 billion kilowatt-hours a year, but to secure the probable illumination level of greatest economic advantage, the consumption at present would be approximately 151 billion kilowatt-hours annually. In other words, the American people would find it to their advantage if they increased the intensity of their present indoor lighting for all purposes by 7 ½ times.

“Our present lighting is far too dim, to suit the known characteristics of the human eye,” stated the authors of the report. “If the general illumination level is brought up to that recommended by the data which have been compiled, there will be gains in comfort, in lessened eye-strain, in economic efficiency, and in the attractiveness of our homes, offices. etc. A noticeable step in the right direction will be a very considerable decrease in glare, and all of its undesirable features, because glare is due, in most cases, to an effort to overcome darkness by a high local illumination of one’s surroundings. By correcting the general level of illumination, glare will tend to disappear, just as draughts (drafts) disappear in a properly heated and ventilated building.”

NEVADA CONSOLIDATED SMOKESTACK BLASTED AT McGILL

An irregular heap of bricks and mortar was all that remained on June 6 of the huge smokestack of the Nevada Consolidated Copper Company, at McGill, Nevada. As a feature of the Lincoln Highway celebration, a blast of 200 pounds of dynamite was fired, a column of black smoke rose from the foot of the stack, and two clouds of red-brown dust puffed out at either side, as the stack avalanched to the ground.

Built in 1913, the smokestack was 800 feet high, 80 feet in diameter at the base, and 20 feet at the top. Since installation of the new Cottrell precipitator in the spring, the old stack has not been in use.

MERCURY PRODUCTION WAS INCREASED IN 1929

The production of mercury in the United States in 1929, amounted to 23,862 flasks of 76 pounds each, according to the United States Bureau of Mines. The calculated value of the production, using the average price of mercury during the year, is $2,892,688. This is the largest domestic production since 1918, when 32,450 flasks were produced, but is only about 78 percent of the average annual production from 1850 to 1921, inclusive. The incentive to produce was greater in 1929 than during the period 1850 to 1921, as the average quoted price was approximately $122 a flask, compared with $48 a flask for the period 1850 to 1921. The production of mercury in 1928 was 17,870 flasks of 76 pounds each, having a calculated total value of $2,207,003.

California again led the mercury-producing states in production in 1929, with an output of 10,139 flasks. Nevada was second with 4,764 flasks, followed by Oregon with 3,657 flasks. Washington produced 1,397 flasks, and Texas, Arizona and Alaska, together, 8,725 flasks. In addition to the above, 171 flasks of mercury was produced in Nevada from gold and silver pan-amalgamation tailings. In 1928 the production, by states, was as follows: California, 6,977 flasks; Nevada, 2,867 flasks; Oregon, 3,710 flasks; and Texas, Washington and Arizona, together, 4,816 flasks. Secondary mercury, from pan-amalgamation tailings, in Idaho and Nevada, in 1928, ammounted to 414 flasks.

The principal mercury-producing mines in 1929, were:
The mines of the Arizona Quicksilver Corporation, and Mercury Mines of America, Gila County, Arizona.
The Sulphur Bank Mine, Lake County; La Joya, Knoxville, and Aetna Mines, Napa County; New Idria Mine, San Benito County; Oceanic Mine, San Luis Obispo County; New Almaden Mine, Santa Clara County, and the Cloverdale Mine, Sonoma County, in California.
The B & B and Red Rock properties, Esmeralda County, Juniper (Nevada Quicksilver), and Pershing Mines, Pershing County, and the Castle Peak Mine, Storey County, in Nevada.
The Black Butte Mine, Lane County, and the Opalite Mine, Malheur County, in Oregon.
The Big Bend, and Chisos Mines, Brewster County, Texas.
The mines of the Barnum-McDonell Mercury Company, and Morton Cinnabar Company, Lewis County, Washington.

In 1929, 14,292 flasks, valued at $1,441,142, were imported, compared with 15,378 flasks, valued at $1,572,017, in 1928. Of the quantity imported in 1929, 9,412 flasks were received from Spain, 1,249 flasks from Belgium, 892 flasks from Italy, 701 flasks from Germany, 323 flasks from France, 1,209 flasks from Mexico, 498 flasks from Canada, and 13 flasks from Peru. In 1928, 6,108 flasks came from Spain, 5,642 flasks from Italy, and the remainder from other countries.

Production in the United States plus imports indicated 37,974 flasks of mercury, made available in 1929, compared with 88,248 flasks in 1928.
