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 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, 1913, Vol. 6 The recovery of the gluten and the bran was an important step forward, but one of the most valuable parts of the corn was still allowed to go to waste, viz., the germ, which yields the oil. There was no incentive to recover it, since no one seemed to want the oil. Had it been produced on a large scale, there would not have been a market for it, although it was realized, even in' those early days, that a vegetable oil of the character of that obtained from corn must eventually become a valuable article of commerce; so it did, but it took many years of hard work to bring about this condition. Shortly before I entered the business, less than 15 years ago they had just started producing corn oil on a large scale but had no market for it - the oil went begging; that was a serious condition. The Chicago factory produced at that time about pounds of oil per day and selling as it did for less than 15 cents a gallon, the revenue from this production was but two hundred and fifty dollars. To-day the value of a gallon of corn oil is nearly 50 cents, and the amount of oil recovered from the same number of bushels as in the Chicago factory is worth This is not due altogether to the increased selling price, but also to the greater efficiency prevailing in the separation of the germ, and the extraction of the oil resulting in a yield three times larger than in the days of the Chicago factory. To-day the gross value of the oil recovered from one bushel of corn, together with that of the oil cake obtained as a by-product, is equivalent to 25 per cent of the purchase price of the corn. The ingenuity of the chemical engineer did not stop there. The price of glycerine was rising steadily, hence the proposition suggested itself of separating the glycerine from the fatty acids. What this meant is evidenced when I recite that glycerine to-day sells at 18 cents per pound and corn oil at about 6'/z cents, 'and that 100 pounds of corn oil yield twelve pounds of glycerine; the price of crude oil and fatty acid is substantially the same.

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. 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.
