Abstract : Progress was extremely limited in the second quarter of FY82 because of the delay in funding which resulted from the very late approval of a national budget. However, there was significant progress in several of the work units as summarized below: A preliminary specification for a Navy-formulated neoprene rubber has been developed and is being exercised on SQS-56 transducers. Electrical resistivity in neoprene rubber has been quantitatively linked to carbon black content. The dependence of the corona inception voltage upon electrode dimensions, gas gap dimensions within the transducer, and gas type and pressure is reported. The instruction entitled 'O-ring Installation for Underwater Components and Applications,' by C. J. Sandwith, has been published as NRL Memorandum Report 4809. A report entitled ' A Generalized Handbook Reliability Description of the DT-513A Preamplifier,' by R. L. Smith, has been issued as Texas Research Institute Report No. 8185. (Author)
