Abstract

1,261,048. Pressure indicators. JOUVENEL & CORDIER S.A. March 26, 1969 [March 26, 1968], No.15932/69. Heading G1L. In a fluid-pressure indicator having a first diaphragm 4 overlaid by a second diaphragm 5 having one or more slits therein the arrangement is such than application of pressure through a bore 2 expands the first diaphragm 4 which distorts the second diaphragm 5 to open the slits to expose part of the surface of the first diaphragm 4 which is visually distinctive from the second diaphragm 5.
