United States Naval Applied Science Laboratory has been installing and retrieving deep sea mooring installations in southeastern part of Tongue of Ocean (TOTO), Bahamas since 1965;conventional moorings, such as vertical "taut-wire" rope moorings, as well as moorings of more complex design have been used to expose variety of metallic and nonmetallic materials;because of loss of one mooring, multiple recovery systems was designed;new array, materials under exposure, and operations connected with installation are described.

Birnbaum, L.S.Bukzin, E.A.Saroyan, J.R.Leon S. Birnbaum holds a B.S. degree in Chemistry from City College of New York. He has completed graduate work in Chemistry at the University of Maryland and Temple University
and in Technology and Management at American University. He has been with the Navy Department Washington since 1949 and is currently Head of the Coatings and Chemistry Branch of the Materials Development and Application Office of the Naval Ship Engineering Center. Responsibilities of this Branch include such items as coatings corrosion control techniques insulation chemical cleaning water treatment toxicology and detection and decontamination of biological and chemical warfare agents. Prior to this Mr. Birnbaum was employed in the Industrial Test Laboratory Philadelphia Naval Shipyard from 1938 to 1949. Work during this period included supervision of a section which inspected paints and allied materials and petroleum products to determine their suitability for Naval use and direction of research in fire retardant treatments. He is a member of the American Chemical Society
Washington Paint Technical Group. National Association of Corrosion Engineers and the American Society of Naval Engineers. Mr. Bukzin is a research and development program manager in the Naval Ship Systems Command of the Department of the Navy in the fields of non-metallic materials
fuels lubricants cold weather operations and several other areas. He is a graduate chemical engineer from New York University with additional training in naval architecture and management which culminated in his participation in the Senior Development Program at Cornell University during the summer of 1960. He has been employed by the Command and its predecessor for the past 2b years and has been in his present position of R&D planning and programming for the past six years. Prior to that his major technical responsibilities were in the field of elastomers and their applications. He received several awards and published a number of papers during those years. Mr. Bukzin is a me

Dynamic walking on bipedal robots has evolved from an idea in science fiction to a practical reality. This is due to continued progress in three key areas: a mathematical understanding of locomotion, the computational ability to encode this mathematics through optimization, and the hardware capable of realizing this understanding in practice. In this context, this review outlines the end-to-end process of methods that have proven effective in the literature for achieving dynamic walking on bipedal robots. We begin by introducing mathematical models of locomotion, from reduced-order models that capture essential walking behaviors to hybrid dynamical systems that encode the full-order continuous dynamics along with discrete foot-strike dynamics. These models form the basis for gait generation via (nonlinear) optimization problems. Finally, models and their generated gaits merge in the context of real-time control, wherein walking behaviors are translated to hardware. The concepts presented are illustrated throughout in simulation, and experimental instantiations on multiple walking platforms are highlighted to demonstrate the ability to realize dynamic walking on bipedal robots that is both agile and efficient.

HANSEN, O. RICHARDUHLER, DALE G.O. Richard Hansen obtained a BSCE from Colorado State University in 1950 and has participated in continuing educational courses at the University of Washington
Wayne State University and the University of Michigan. He was employed at Puget Sound Naval Shipyard for five years as a Mechanical Engineer and Project leader in industrial gases and cryogenic O2. Producers for Shipboard Applications followed by seven years at Chrysler Corporation initially as a project engineer in the FBM program subsequently assigned to Mechanical Laboratory achieving Managing Engineer status of a department therein which contained the facilities group instrumentation group and an experimental machine shop. This was followed by employment at Westinghouse Astronuclear Laboratories as a senior engineer conducting studies in two phase liquid hydrogen flow in simulated NERVA cores. Following this he served two years of employment with the Lockheed Georgia Company conducting material studies in combined nuclear cryogenic environments at the NASA 60 megawatt test reactor located in Sandusky Ohio. Joined NAVSEC in 1966 as a mechanical engineer in the compressed air systems group and has been assigned to the Supervisor of Diving Salvage and Ocean Engineering conducting analysis and evaluation of compressed air and gas systems associated with diving and salvage operations. Dale G. Uhler received BSCE degree from Carnegie Institute of Technology in 1964. He spent two years as a construction engineer before entering graduate school at the University of Miami
Florida where he received his MS degree in applied mechanics with a minor in Ocean Engineering in 1968. He is now employed as an Ocean Engineer in the office of the U. S. Navy Director of Diving Salvage and Ocean Engineering where he is the project manager for the Large Object Salvage System and related development programs and concurrently working toward his Ph. D. at Catholic University.
The advent of deep ocean technology has created a need of buoyancy at ever increasing depths. This paper concerns itself with two most widely used techniques for dewatering/deballasting, compressed air supplied by sur...
