Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineers, 1912, Vol. 5 If we first produce the pure crystalline phenol-alcohol, contain ing no excess Of phenol, for instance crystalline saligenin or oxybenzyl-alcohol, and if we heat it gently, it will simply dehydrate and be transformed in a fusible mass which on cooling, solidifies to a resinous product - a fusible saliretin resin. The latter, submitted to the further action of heat, polymerizes and becomes an infusible, insoluble saliretin. This polymerization is facilitated, by the pres ence of small amounts of catalyzers, for instance, hydrochloric acid. The presence of an excess of phenol retards polymerization; hence the infusibility induced by polymerization will be retarded, and this, until some way or another the excess Of phenol has been expelled. The infusible polymerized saliretin obtained by heating phenol-alcohols containing no free phenol, or by heating fusible saliretin containing no free phenol, is insoluble in alcohol, but swells in acetone; it softens decidedly on heating, although it is no longer fusible. Longer heating does not harden it further, nor make it more resistive. It is harder, stronger, and more resistant to physical and chemical agents than the fusible saliretin from which it is derived; in this respect, it surpasses even more the soluble fusible resins described by Blumer, delaire, Baekeland, and called phenol resin by Aylesworth. But even after polymerization or hardening has been carried as far as possible, it is considerably less hard and less strong and less resistant to physical and chemical agents than the polymerization products resulting from the reaction of phenol on a sufficiently large proportion of formaldehyde or equivalent substances. In order to obtain the latter polymerization products of maxi mum strength. Hardness, and maximum resistivity, an adequately larger amount of methylen group must be introduced before or dur ing the act of polymerization. The introduction of this methylen group may be accomplished by at least three distinct methods. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 12: Part II, 1919 The American Institute of Chemical Engineers is composed of men who are, above all, intensely practical: men who make it their like work to apply chemistry to useful ends. We have come to Savannah not merely to enjoy a proverbial and graciously extended hospitality, but chie y because we recognize that here there is much for us to learn. Your cotton oil mills, your great fertilizer fac tories, the secrets of your naval stores industry, the doors of many plants distinctively Southern in their type have been generously Opened to us. We Shall take with us on our return new and endur ing impressions of Southern courtesy and kindliness, convincing evi dence of the magnitude of industrial achievement in the South, and a new appreciation of the wealth of resource and of opportunity in this supremely favored section of our country, but our mission will have failed unless we leave behind us a message so vital and direct in its importance that it secures and holds your attention and thereafter in uences your action. It is no new message: it is the same in import as that carried by the American Electrochemical Society on its Southern tour in 1918; it was voiced and developed by many authorities of national reputation in the remarkable issue of September 14, 1916, of the Manufacturers Record; it has appeared on many editorial pages and in many government publications, and I myself have had the privi lege of bringing it to representative bodies of Southern scientists and business men. And that message in a word is this: The Future of the South is in Chemistry. To ensure acceptance any such general thesis properly requires demonstration. Suppose we begin by considering for a moment what the South already owes to chemistry. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineers, 1920, Vol. 13: Part I The paths of the early workers on electrolytic cells were not strewn with roses. They were very rocky. I speak from experience for I think I have been continuously in the business longer than any other man in this country. In September, 1894, I went to work for the old Electrochemical Company of Rumford Falls, Maine, as a laborer, 20 months later I was made superintendent of the plant, and have held that position there, and subsequently in Berlin for the Brown Company. That makes 26 years of experience. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 13: Part II, 1920-21 Sulphur plays a more basic role in chemical industry than any other element. Either as elementary sulphur or combined as a metallic sulphide, it is the source of all sulphuric acid. Hence any changes in the sulphur industry Should be of great interest to the chemical engineering profession. America now dominates the sulphur industry and virtually all the American sulphur is produced by three companies - viz., the Union Sulphur Co., the Freeport Sulphur co. And the Texas Gulf Sulphur Co. These three companies produce not only virtually all the sulphur used in the United States but also a considerable surplus which is exported. The only other sulphur which normally enters the American market in quantity comes from Japan1 and its per centage calculated on the consumption of the United States is small and is not likely to increase. Rising costs of living have meant much higher wages in Japan, as well as in other parts Of the world; in fact, the percentage increase has probably been greatest in Japan, due not only to world conditions affecting all countries but to the rising standards of living of the Japanese. These facts, together with present higher transportation costs, will make it increasingly difficult for Japanese sulphur to compete on our Pacific Coast with the American product.

Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 14: 1921-22 Sulphuric acid is universally concentrated by the application of heat. The first interest of the designer of apparatus to concentrate sulphuric acid must hence lie in the thermal properties of sulphuric acid. Several articles have been written on this subject, and one of them at least has treated the subject very thoroughly and comprehensively. The results, however, are not most conveniently expressed, and the original article is not particularly accessible. This, then, must be the excuse for the present attempt to present an old subject from a different viewpoint. The first thermal property of sulphuric acid which interests us is its specific heat.

This book was released on 2015-07-05 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 11: 1918 Gentlemen: Your secretary has asked me to write a few introductory remarks concerning the mills of the Brown Company located in Berlin, N. H., and I have chosen as my subject "The Human Element in the Mill." In order that these remarks may be clear, it will be understood that the Brown Company is a consolidation of two distinct companies which were under two distinct systems of management. One has always been under the Brown management. As it would take too much space to go into the separate activities of each, and as it is not my object to write a history but to lay down certain principles and show how they are applied, I am writing of the Company as if it had always existed as one organized entirety instead of two separate institutions. However, it must be borne in mind that the unfavorable facts herein mentioned took place in one of our mills before it came under the Brown management. In writing this paper certain things do not appear in plain English, and for the true meaning of a part of my message one will have to read between the lines correlating the principles with the facts laid down. I have arranged this paper in regard to sequence of principles, and consequently, the facts are not arranged in accordance with sequence of events. The charts submitted are illustrative of principles, and if they contain any other information such information is of only secondary importance. Lest I become tedious I shall confine myself to one illustration of each principle. Undoubtedly the most important factor in the development and operation of a mill is the human element. In this mill we have thirty-six nationalities and I do not know how many religions. We have Republicans, Democrats, Socialists, Prohibitionists.

Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineering, 1914, Vol. 7 Chemical engineering as an organized profession is comparatively new, although many men have been engaged in this class Of work since the beginning of large-scale manufacture. Since the organiza tion Of this Institute, various definitions have been given to outline the scope of our professional activities, many schemes have been suggested to improve the training of our apprentices, some advances have been made towards standardization in our engineering practice, a code defining the ethical standards of our profession has been formulated and adopted, and we have shown our aims, with some results, in constructive patent reform. Work of such a character is of the greatest importance, and is far in advance of that heretofore undertaken by any other organization in our field. It can never be regarded as completed, and the best thought and effort Of well constituted committees will continue to be given to advancement along these lines, with great resultant benefit to the profession.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 9: 1916 When by unforeseen circumstances a nation is suddenly plunged into conditions depriving it of materials necessary for its welfare, it becomes an eminent duty of such a people to take immediate steps to attempt to restore the supply of the wanting essentials. Since history ever repeats itself, the assumption can at once be made that such conditions must have been taken under advisement long before there was any evidence of their becoming actualities, but the presumable optimistic trait in human nature and without which we would not be able to live through a happy existence, will procrastinate the evil day, with the intention of relying on the strength of the country when the necessity arises. Recent events, however, have proved that this is no easy matter and the effort made in this direction, by making an inventory of our supplies, brings us to face the question of crude material, a question which is of the utmost importance in order that our stocks may be sustained. The United States is a country of immense resources, but owing to territorial advantages or seasonal conditions, it follows that some of the basic needs are entirely wanting or so limited that they may be considered a negligible quantity. No matter if we are surrounded by a high protective duty or laboring under a tariff for revenue simply, at least that in name, which obviously means nothing at all, instances will always remain where desirable commodities are lacking.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Transactions of the American Institute of Chemical Engineering, Vol. 10: 1917 When we speak of resources we usually have in mind material things, such as financial resources, mineral resources, agricultural resources, etc. It would appear, however, that this is a rather limited construction of the meaning of the word "resources," for with all of these material resources there is the presupposition that one has the ability to use them. Wealth owned by an idiot may not be to him a resource, but rather a liability. A mining deposit that no one knows how to work is hardly worth calling a resource. Wonderfully fertile fields in the center of Africa are not resources, to the extent that they are removed from the intelligent use of civilized men. In our own country it is true that wealth, mineral deposits, and fertile fields are resources, but they are such because there are resourceful men in our country who can use them. If the present war teaches us anything, it is this: In these days wars cannot be won because a nation has great material resources only, but rather because a nation has resourceful men. Let us consider this carefully and see whether what I have said is true and what, if it is true, it implies. Mexico is a country that is wonderfully rich in possibilities. Unfortunately for Mexico, whatever the cause may be, the Mexicans have not, themselves, so far developed their possible resources to their country's full advantage. In so far as these resources have been well developed, it has been because resourceful men have gone to Mexico and endeavored to turn mineral and agricultural resources to profitable ends.

It is entirely impractical for use on alloys high in zinc. The only installation used for copper alloys is used on leaded bearing bronze, the new lead being added in the ladle. Much lead is volatilized from the scrap in the charge, and much fume results, giving bad working conditions. The installation of Snyder furnaces has a very poor power factor, though this is not necessary in a direct arc furnace.
