Abstract

1,111,614. Measuring fluid flow. BRITISH OXYGEN CO. Ltd. July 28, 1965 [April 28, 1964], No.17647/64. Heading G1R. In a fluid flow indicating device in which a gas, such as oxygen, from a source 1 passes through a regulator 6 and a non-return valve 8 to a mask 2. The movable valve member 11 is pressed against a seating 12 by a spring 13 when exhalation occurs in the mask 2 but should a leak occur in the pipe 3 during such period gas will pass through a pressure responsive device 10 to complete an electrical circuit to a bulb 14.
