Abstract

1,105,861. Respiratory appliances. LONGWORTH SCIENTIFIC INSTRUMENTS CO. Ltd. 21 Feb., 1967 [9 March, 1966], No. 10377/ 66. Heading A5T. [Also in Division G1] In a gas pressure warning device, such as for use with medical gases, gas normally passes through a port 6, in a gas supply line between a supply cylinder and a patients mask, to enter a reservoir 8 through a spring loaded valve 9 but sould the gas pressure at the port 6 drop the valve 9 will close and the pressure difference through ducts 10, 11 on the upper and lower sides of a diaphragm 5 will cause the diaphragm to move againt a spring 14 and allow gas, under pressure from a reservoir 8, to operate a whistle 13.
