R. B. Sosman, * Kearny, N. J.—Mr. Sweetser brought out that in certain blastfurnace slag compositions a change of one or two tenths of a per cent may be quite significant. That is true not only of blast-furnace slags but of other compositions as well. We have all been up against the necessity of having to plot out equilibrium diagrams of this kind on a big enough scale so that we could actually use them, the

The control of dusts and fumes of submicron size is involved in many process industries. This paper presents in tabular form the quantitative data from a number of metallurgical operations and discusses allowable discharge in terms of effluent-weight ratio. Typical installations for recovery of stack effluents are cited.

Although previous studies l,2,3 have been made, no correlations for pressure drop have been proposed. This is probably because severe particle breakage occurred and pressure drops changed substantially with time. A quantitative statement of the relationship of pressure drop to the parameters of the system is desirable for lignite since, unlike higher rank coals, lignite slurries are thixotropic. The present investigation was undertaken to quantify the pipeline behavior and required continuous monitoring of pressure drop and size distribution.

The late Dr. Ebenezer Emmons of Albany, one of the geologists of the Survey of New York and the author of The Taconic System, brought to notice as early as 1838" a peculiar concretionary and lamellar form of phosphate of lime, to which he gave the name Eupyrchroite, from the Greek words for fire and color, with the pefix

CERTAIN titanium alloys when quenched to retain the 0 phase at room temperature show extensive transformation of 0 to martensitic a during deformation. Alloys of this type are usually characterized by low tensile yield strength, a large spread between yield strength and ultimate strength, and high uniform elongation. A previous investigation of this phenomenon concluded that the principal contribution of the martensitic transformation was to increase the amount of deformation prior to fail-

Higher education is in serious trouble in the United States. With increasing costs threatening to create a taxpayer's revolt, serious thought must be given to determining whether or not we can continue to afford our present educational policies. Disinterested students with little aptitude are pushed into over- crowded universities by well-meaning parents, but they lack real objectives beyond achieving that great status symbol-the degree. Advanced degrees are heaped upon the baccalaureate degree, and the pursuit of the pure and social sciences continues at the expense of engineering and technology.

Howe Memorial Lecture The Howe Memorial Lecture, in memory of Henry Marion Howe, Past President of the Institute, was authorized in April, 1923, as an annual address to be delivered by invitation under the auspices of the Institute by an individual of recognized and outstanding attainment in the science and -practice of iron and steel metallurgy- or-metallography, chosen -by-the Board-of Directors upon recommendation of the Iron and Steel Division. The following were the Howe lectures and lecturers for the years indicated 1924 What is Steel'., By Albert Sauveur.

MetALLOGRAPHIC investigations of composites of zinc alloys and aluminum have been made to study the effects of various thermal treatments on the zinc-alloy grain size and diffusion of zinc into the core material. The use of various alloys of zinc has necessitated the development of a universal etchant which will allow microscopic examination of the zinc grain size regardless of the composition.

First actual production of titanium metal at the newly constructed Henderson, Nev., plant of Titanium Metals Corp. of America occurred in mid-October. Production will be expanded rapidly until the initial goal of 10-tons per day is reached. This will be equivalent to eight times the present world production of titanium metal. W. Eberstady & Co., New York City, has announced plans for construction of a $400 million plant for the manufacture of synthetic liquid fuels from coal in southern Illinois, if the Government will guarantee a minimum price for the gasoline and other products to be produced.

In a recent publication in the SME Transactions of September, 1975, Volume 258, entitled “Potential for Further Lowering Sulfur in Intensively Cleaned Coal at Mines,” the writer discussed: (1) technical findings useful for the management of reserves to further lower sulfur in intensively cleaned coal and (2) a future coal preparation plant concept for the intensive cleaning of sulfur. The purpose of this technical note is to (1) illustrate the nomographs that can be formed when recovery is phased in with previous work, (2) make note of the powerful potential for predicting future cleaning performance in unmined areas, and (3) discuss resulting mathematical interrelationships.
