Metropolitan Section SNAME Hears Technical Paper On Finite Element Analysis Techniques The New York Metropolitan Section of The Society of Naval Architects and Marine Engineers held its February meeting at the Whitehall Club in New York City. The technical paper presented at the meeting was entitled "Prac- tical Procedures for Technical and Economic Investigation of Ship Structural Details." The authors were Donald Liu and Abe Bakker of the American Bureau of Ship- ping. Mr. Liu gave the paper, which included a slide presenta- tion. The paper brought to the atten- tion of the marine industry that costly repairs and lay-up time of a vessel due to structural failures can often be prevented, provided that problem areas are recognized and investigated in the ship de- sign stages. In this regard, local structural problems and resultant failures are frequently the result of stress concentrations. It was shown that the application of fi- nite element analysis techniques can be economically employed in the investigation of structural de- tails. Additionally, practical pro- cedures for analyzing structural details, including cost analyses, were presented in the paper.

(N62794-70-C-0010) Portable Ventilation Equipment Catalog Offered By Coppus A new 38-page catalog covering performance, dimensional, techni- cal and application data on 33 dif- ferent models of Coppus portable blower exhausters and accessory equipment, plus welding fume arm systems designed for use with portable welding fume exhausters is now available. The catalog contains detailed descriptions of air, steam and water-driven turbine types, gaso- line engine and electric motor- driven units, Venturi blowers with no moving parts that operate on air or steam, and a unique air- driven reaction fan blower exhauster. Performance tables and techni- cal data make it easy to select the "just-right" ventilator for a specific application. Performance tables show free air capacities, performance at various static pressures, and air flow through flexible duct. Technical data in- cludes sound levels for each type unit and friction loss curves for flexible duct, water and com- pressed air hose. Coppus's broad line of blowers, blower Exhausters and ventilators include designs that are specifi- cally engineered to help meet OSHA and local ventilation safety requirements established for re- fineries, petrochemical, chemical processing, manufacturing, fab- ricating plants, construction sites and onboard ship applications. All Coppus portable ventilators are constructed to withstand the abuse associated with rigorous in- dustrial use. The catalog is profusely illus- trated with application photo- graphs and drawings showing air flow patterns in typical ventilat- ing applications. A listing of the company's worldwide sales office and service center locations is also provided. For a copy of Catalog No. 100, write Anthony Pandiscio, Coppus Engineering Corporation, 344 Park Avenue, Worcester, Mass. 01610. Harry R. Kraus Appointed VP At Dravo Division Harry R. Kraus Harry R.
