Abstract

1,187,926. Pressure gauges. SAMUEL JONES & CO. (ENG.) Ltd. Feb.27, 1969 [March 1, 1968], No. 10074/68. Heading G1L. In a visual indicator 1, secured in the wall of a pressure filled vessel, an element 10, 11 is held in a central position in an aperture 9 by the pressure within the vessel distorting a diaphragm 7 to press the portion 11, of the element 10, 11, against a cup-shaped member 8 and release the element 10, 11, to fall under gravity, when the diaphragm 7 flattens owing to the pressure drop within the vessel.
