Abstract
969,679. Leak testing. BELEGGINGSMAATSCHAPPIJ MARGARITA N.V. May 11, 1962, No. 18229/62. Heading G1S. Apparatus for detecting leaks comprises a resiliently-edged cup 10 for applying over the suspected area of a surface 12 and an indicator tube 14 containing a foam plug 16. This may move in either direction past a scale 17 to indicate leakage in either direction. The indicator tube may include a flexible portion or, as shown in Fig. 4, be provided with a universal ball joint for use with non- horizontal surfaces:reduction of dead space in the cup increases sensitivity. The cup may be shaped for application to special forms of surface e.g. pipe joints (Fig. 10) or acute angles (Fig. 12), a resilient gasket being provided around the contacting edges. For ferrous metal surface the cup may be provided with holding magnets. The embodiment of Fig. 13, for use with corrosive &c. gases, includes an expansible bellows 85 for trapping the gas, expelled air moving the foam plug.
