Excerpt from Transactions of the American Institute of Chemical Engineering, Vol. 1 of 12 The Snyder or any other direct arc furnace is applicable only to true bronzes or other alloys low in zinc, 5% zinc being the probable limit. 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.

Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 9: 1916 Numerous writers and Speakers have called frequent attention to the great service which chemistry has rendered to humanity. In every field of industry she has been active, every product of man's labor has felt her magic touch. Modern civilization can be meas ured most accurately by considering the influence which chemistry has had upon industry and industrial operations. It is unnecessary here to tell what she has done. We are more concerned with the future than with the past, and judging the future by the past, the benefits which chemistry during the coming years will confer upon humanity will be infinitely valuable. On us, her votaries, is imposed the task of laying out the course of her progress, preparing and making the way easy for her and heralding her triumphant march. It is the purpose of this paper to indicate how this may best be done. It should be perfectly obvious that the purpose of all industry is to satisfy the desires of human beings. This is as true of chemical industry as it is of any other industry. The chemist renders human service. He is a human being himself and his service to human beings makes him a part of a great democratic commonwealth in which every member is a factor in the development of the whole. The Chemist is only a fraction in this commonwealth but the more he is organically a part of it the greater is his power of service. Like everyone else he does not exist by himself alone but is depend ent for his existence upon every other human being that is a part of the social organism.

Excerpt from Transactions of the American Institute of Chemical Engineers, 1908, Vol. 1 First - The proposed organization should be called the American Institute of Chemical Engineers. Second - The Institute should not attempt the publication of a journal, but should confine its publications to a volume or volumes of transactions.

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.

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.

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.

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.
