| Proposed Work. It is proposed to try various manifolds as shown in Fig. (6) on a standard Bentley, and to try an interference scheme similar to No... special system, having various lengths of interference pipe. It will then be necessary to obtain silence on a par with standard Bentley without materially increasing the power loss if this can be done. Ea/Ed. {J. L. Edwards} | ||
