<p>1,119,687. Jet propulsion. BUEHLER CORP. 21 Nov., 1966, No. 52005/66. Heading B7V. [Also in Division F1] A boat 10, Fig. 1, is driven by a pump 13 (see Group F1) receiving water through an opening 12 and discharging it as a jet through a convergent outlet (100A), Fig. 2 (not shown). The pump is driven by a marine engine 14 through a shaft 15 and a universal joint 24. The convergent outlet may be closed by a conical valve (111) so that the pumped water can be delivered for other applications, e.g. fire-fighting.</p> |
