E41R1 POINT SOURCE GAS ALARM
Abstract
Further research and development tests and engineering developments have taken place in the following portions of the alarm: (1) experimental and original design air pump tests; (2) several areas of electronics have been modified and tested, including the tape transport drive system, radio interference studies, and engineering studies of the low-voltages cutoff, the regulated voltage, and the alarm light oscillator circuits; (3) new materials and designs of the fluid pump were tested; (4) improvements to the alarm case to enhance water-tightness and ruggedness; (5) investigation into alarm transportability; (6) impact tests and correction of tape drive retraction snubber; (7) development of modified vacuum sensor switch; and (8) analysis of photometer head problems.
