Abstract
25,572. Crick, E. H. Nov. 7. Direct gas-pressure apparatus, non-automatic.- For admitting gas to a closed vessel for delivering the liquid contents under pressure, a gas-container 7 is supported by the stopper 1 within the vessel, and the valve of the gas container is opened by hand by pressure on a flexible diaphragm 4. If the pressure inside the vessel is too high, the diaphragm 4 becomes distended so as to prevent the valve from being opened.
