Patent number: 5297409Abstract: A hole is formed in a high-strength steel part and a lubricant consisting essentially of one or more metal powders, preferably of nickel or molybdenum; a metal powder which is more reactive than the steel of the workpiece such as zinc; and an organic medium is applied. A forming mandrel having a generally cylindrical shape with a frustoconical portion on either end is centered over the hole. The mandrel is pushed through the hole at a rate such that the steel adjacent the hole is coldworked and its microstructure is transformed from an austenitic to a normal tempered martensitic structure.Type: GrantFiled: June 22, 1992Date of Patent: March 29, 1994Inventors: Danny L. Beaman, Kenneth R. Christie, Dennis M. Cordy, Craig W. Graham, Steven W. Lightle, Michael L. Watts

Patent number: 4119941Abstract: An acoustic coupler is provided for extending the listening and signal garing capabilities of an existing cable connected hydrophone system. The acoustic coupler includes a sensor, such as an additional hydrophone, an acoustic projector, and a cable which electrically connects the acoustic projector to the additional hydrophone. A modulator is interconnected in the cable between the projector and the additional hydrophone for modulating signals received by the additional hydrophone on a carrier wave which is within the bandpass of the existing hydrophone. With this arrangement the acoustic projector can be placed in water within listening distance of the existing hydrophone so that signals from the additional hydrophone can be transmitted over the existing hydrophone and its cable system.Type: GrantFiled: August 8, 1977Date of Patent: October 10, 1978Assignee: The United States of America as represented by the Secretary of the NavyInventors: Donald K. Moore, George R. Beaman, John D. Hightower, Craig W. Graham, Jr.
