Urban redevelopment projects are occurring more frequently than ever before as urban greenfield sites become limited and city planners and devel- opers attempt to revitalize existing underdeveloped neighborhoods. How- ever, because of the past usage of many urban sites (some dating back 100 years or more), designers and construction teams have to not only engineer founda- tions to accommodate the subsurface soil and ground water conditions, but also to work around the relic founda- tions or structures that have been left behind from previous developments. In these cases, a one-size-fits-all approach to foundations may not yield the most cost- and schedule-effective approach, and hybrid foundation systems have to be evaluated.

Faulty insulators on mine trolley/track haulageways may allow the flow of leakage currents into the mine roof and ultimately result in combustion of the local roof material. The National Institute for Occupational Safety and Health (NIOSH), Pittsburgh Research Laboratory (PRL), has devised a passive means to detect overheating insulators on direct current systems. The detector consists of a spring-loaded cartridge that ejects a reflective streamer of white Teflon tape when subjected to elevated temperatures. The cartridge assembly can be easily installed over the outer metallic shell of an existing trolley line insulator. If an insulator overheats due to ground leakage currents, the visible streamer alerts mine personnel traveling on the haulageway.

The sum of $250 was appropriated to the Chicago Section. The President was authorized to appoint five members of the Board of Directors, including himself as Chairman, to discuss with other technical societies the proper organization for handling all matters of joint interest to the profession of engineering as distinct from purely technical activities, and to submit its findings in the form of recommendations to the Board of-Directors. Charles F. Rand was appointed a Trustee of the United Engineering Society to succeed himself. John H. Janeway was elected a member of the Library Board, vice Karl Eilers, resigned. Alexander C. Humphreys was elected a member of the Library Board to succeed himself.

This paper discusses design and construction aspects of shaft construction through rock saturated with petroleum hydrocarbons (crude oil). During the subsurface exploration phase for design of the Hilltop Interceptor project in Cleveland, Ohio natural crude oil was encountered at depths between 6.1 and 61 m below ground surface. The oil-saturated Euclid sandstone contained up to 12,000 mg/kg total petroleum hydrocarbons (TPH), various volatile organics, and had flash points as low as 18.9°C. Interceptor hydraulic design required that construction of access and/or drop shafts penetrate the layer of petroleum hydrocarbon saturated rock. This led to the design of a special lining and some special handling procedures for the excavated material.

The United States Department of Energy, through its contractor Lawrence Livermore National Laboratory, has entered into a contract with Alpha-IRECO, Inc. for the emplacement of approximately 2.9 million pounds of a 50% RX-MD emulsion 50% ANFO blend into an underground chamber for initiation to produce the 12 trillion caloric equivalent of 1,000 metric tons of TNT. The detonation will be closely monitored to determine the characteristics of a large chemical explosion for comparison with data collected from previous like-sized nuclear events in the same location. This data will be shared with former Soviet block countries to facilitate enforcement of the various non-proliferation treaties currently being negotiated between the countries.

World demand for metallized iron continues to increase, keeping pace with steelmaking requirements for lower-cost hot metal. Virgin iron ore and in-plant oxide fines can be reduced to direct reduced iron (DRI) and hot-briquetted iron (HBI). Maumee Research & Engineering Inc. (MR&E) developed an improved coal-based process for the cost-effective production of either DRI or HBI. Starting with dry compaction, the process combines the latest technology for material preparation, rotary hearth furnace construction and environmental control. Coarse iron ore fines are blended with pulverized nonmetallurgical coal to produce a highly metallized (>90%) product. This paper presents production and installation cost data based on operating and under-construction iron oxide reduction facilities.

For the last several years, a systematic investigation of the equilibrium extraction behavior of selective tervalent lanthanides with representative chelating extractions of a variety of chelating agent families has been undertaken for the purpose of learning how to obtain chelating extractants of improved selectivity for separating individual lanthanide ions. The equilibrium extraction data (expressed as log Kex) for each reagent system are linearly related to the reciprocal ionic radius of the tervalent lanthanide ions. The role of adduct formation, steric hindrance, as well as the nature of the bonding atom in the chelate ring, represent some of the factors affecting selectivity arising out of our database of over 200 individual extraction systems, which will be discussed.
