A comprehensive finite element formulation for thermo-elastic consolidation based on a general variational principle is presented Sample one dimensional problems associated with isothermal consolidation, heat conduct ion, and thermo-elastic consolidation are presented. In addition, evaluations of thermo-elastic consolidation for an underground coal conversion field site are conducted.

Fear of inflation is one important reason for the rebirth of interest in the stock market, and natural resources are the best investment in an era of rapid inflation.

Two different types of filtration methods for in-situ gasification of coal are described. The different factors, i.e., geological, technological, and others, which affect in-situ gasification are given. The layout and operation of filtration methods of in-situ gasification are described in detail. The results of a case history are described.

The Circuitron herein described applies current from the classifier motor circuit and energy from the sound of grinding media to move an oscillating disc. The disc through a photoelectric cell controls the speed of the ore feeder and consequently the amount of ore delivered to the mill.

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 out- standing 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.

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

A fast, easy, and inexpensive method of determining the consolidation of overburden in surface mining operations through seismic analysis has been developed. The method involves use of a refraction seismograph which measures overall consolidation of subsurface materials, including such factors as rock hardness, stratification or lamination, fracturing or jointing, and the degree of weathering or decomposition. It also is possible to determine the thickness of various layers of subsurface materials to depths exceeding 100 ft.

ALTHOUGH previous work1 has shown the compo- sition range of the complex face-centered cubic phase,2 Ti2Ni, to be narrow, no precise limits were established. The purpose of this investigation was to prepare homogeneous alloys on either side of the stoichio-

A properly designed pre- and post-grouting program aided with coherent construction sequence and adoption of flexible design approach provide a practical combination to solve excavation problems in a hostile rock environment: intensely fractured and sheared. The Pacheco Pumping Plant demonstrates the utility of an engineered grouting program.

The use of point load test data by the authors to estimate rock mass cohesion is a very ingenious approach. It must be emphasized that this estimate is indeed only an estimate since the point load strength index employed to predict the uniaxial compressive strength (and subsequently predict the cohesion) is likewise only an estimate.

Current theories of fracture maintain that brittle materials contain flaws or regions of weakness at which fracture originates. Whether a particular flaw grows depends upon the stress distribution in its vicinity and upon the presence of other stress relieving mechanisms capable of absorbing the applied energy. Under load, therefore, certain of these flaws will be activated, and the resulting fragments will have a size distribution determined by the spatial distribution of active flaws. Gaudin and Meloy,1 assuming a random occurrence of flaws, have derived the size distribution of fragments as

In the Carlsbad area potash is dry-mined and wet- concentrated. Wet concentration involves recirculation of saturated brines, with resultant difficulties of brine disposal and inherent losses in recovery through solution of the KC1. A dry beneficiation process for potash minerals would offer many advantages over present methods. International Minerals & Chemical Corp. has been working on development of a dry process for some time. This article is a progress report.

THE etch-pit technique for revealing dislocations in bulk samples allows one to determine dislocation densities and to study their behavior under various mechanical and thermal treatments. We have developed a chemical polish-etch for the development of etch pits on the (1100) plane of Cd which appear to
